  The machine shown is of a well-known type. It is fitted with a device, placed at the front of the machine, for the simultaneous entry of identical articles in one or more columns of a form or of an invoice inserted into the machine, this entry being performed during a cycle of printing mechanism operations. Machines of this kind are used by banks, utility companies and similar trading houses for preparing invoices or statements of account.

   These invoices or statements are divided into several vertical columns, so that the same item can be entered in different columns, or else different items may be entered in different columns. These statements or invoices can be divided into two separable parts containing the same material, one of which is provided to the customer and the other is put in filing.



  The specific example chosen to illustrate the application of the machine. represented is the preparation by a bank of statements of current accounts of a number - of customers of that bank.



  The machine described by way of example is provided with several rows of upright keys; these keys register the amounts in the various totalizers of the machine; they also order character wheels for printing this amount on an inscription medium. The machine also has a row of transaction keys for carrying positive and negative items to the totalisers, and a row of symbol keys for printing identification symbols next to the various items.

   The usual totals control crank is replaced by the soot row of totals control keys controlling machine operations, including addition, subtraction, read and reset operations. A key release lever, placed on the right side of the keyboard, is used to release any key pressed.



  The machine shown is provided with a positive device for counting one, under automatic conditions, each time a certain key is pressed - in this case, the check key - during. a ma chine operation. The check counter wheels occupy the first two positions of the scale totalizer row; however, there is no connection between these wheels and the scale totalizer; the check counter automatically counts up to 99 checks. One of the transaction keys, in this case the check correction key, is provided for correcting checks or debits entered in error.

   Pressing this key subtracts 1 from the check counter wheels by adding the additional number 99 to these wheels. Besides the automatic check counter, there is. two rows of keys provided on the left side of the keyboard, and they are used to dial the number of checks in a bundle when the total amount of these checks is entered in a single item during a single transaction of the ma China. Various interlocks control the automatic check counter.



  The machine comprises two lines of totalisers, namely the upper line, called N 1, and a rear line, called N 2. Line N 1 of the totalisers contains the balance totalizer, often called balancer, which calculates positive amounts. and negatives to establish new balances. Line N 2 includes four totalizers, two of which are addition / subtraction totalizers; the third is a debits totalizer, and the last is a credit totalizer.

   It is necessary to provide addition / subtraction totalizers for totaling checks and deposits in view of the need for subtraction operations in the correction of checks and deposits.



  One of the totalisers of line N 2 is used to accumulate a final total of new active balances, and the other to accumulate a final total of new passive balances. During the said new balance operations, these final totals are transferred from the balance totalizer to the corresponding addition wheels of the totalizer line N 2.



  The calculations relating to the updating of particular current accounts are entered on a sheet shown, by way of example, in fig. 2 and 3; this sheet is divided into two parts, one of which is a statement of account, and the other, the stub part, constitutes a sheet of the bank ledger. The statement part is divided into three vertical columns with the respective headings: Debits, Credits and Balance. The heel part has a column for duplicate registration of the scale.

   The Debits portion of the statement is divided into two columns for recording passive items, eg checks, service charges, and so on. The Credits part has a column for entering credits or deposits, while the Balance part consists of two vertical columns for entering the date and the new balance.

   The stub part of the sheet is divided into three vertical columns: the first for the date, the second for entering the total number of checks debited to the account during any update operation, and the third for the inscription of the. new balance.



  Apart from the entries on the statement sheet, a duplicate entry of all transactions is made on a verification strip shown in fig. 18. This verification strip is divided into four vertical columns: the first of these columns must be entered for debits or checks; the second includes loans or deposits; the third column indicates the total number of checks debited to the account during any update operation, and the fourth is used to register new balances.

   It will be seen that the articles are written on this verification strip in reverse order; that is, the number corresponding to the first item on the journal sheet is printed at the bottom of the verification strip, and so on.



  Referring to Figs. 2 and 3, it will be seen that the two parts of the combined sheet are divided into 39 horizontal lines for the item inscriptions; these lines are clicked by numbers in the right margin of the heel part of the sheet. It will also be seen that a space above the first line is provided for the entry of the balance again.



  A table at the front of the machine, capable of horizontal displacement, is provided to bring the sheet. To the printing mechanism. This table presents 39 row positions corresponding to the 39 rows of the sheet, and in addition a normal position or starting position corresponding to the balance position again.

   Nine line selection keys are provided for the ones and three - those of 10, 20 and 30 - for the tens: these keys select the line of the writing medium on which the first entry is made, and after this selection The initial selection, the consecutive advancement of the table and of the sheet continues under conditions of automaticity under the control of the transaction and totals keys.



  When it is necessary to carry over a scale, the old scale is first taken from a previous sheet. Since the balance to be transferred key will have been pressed at the start of this operation, the positioning of the table and the sheet under the influence of the searcher keys will be prevented and the balance again will be printed on. the sheet at the appropriate right above the first line. After this bank carry forward operation, the line finder key N 1 is pressed to select the first line of the sheet, after which the account update operation can be started.

   In general, the rates are entered first, and it will be seen that the Rates part of the sheet is divided into two vertical columns. The first debit item is printed in the first column, the left one, and the second item of debits is printed in the second column on the same row as the first. A third item would be printed on the second line of the first column, and so on until all of the liability items were entered.



  In the following transaction, the credits or deposits are entered on the appropriate part of the sheet. If there is more than one article to be written, the table is advanced automatically, so that these articles are. printed in consecutive order.



  After recording all debits and credits, the new balance is established; this new balance is. printed, with the date, in the appropriate part of the two sections up and heel of the sheet.



  In subsequent entry operations, it is only necessary to press the row search keys which correspond to the first available row of the sheet. After the registration of the first article, the advancement of the sheet is fully automatic, as explained above. At the end of the new balance operation, the table is returned forward to its normal or starting position. The sheet can thus be removed from the table and a new sheet placed in position.



  Referring to fig. 2, it will be seen that the machine shown is arranged to print on 39 lines of a sheet. Immediately after printing the first item on the 39th line, the table is automatically returned to its starting position to draw the operator's attention to the fact that the machine is printing on the last line of the line. leaf. If the operator wants to make subsequent entries on this line, it will be necessary to dial 39 on the search-line keys before each entry, since the table is automatically reset to the starting position after each entry.



  Referring to line 37 of FIG. 2, it will be seen that two debits, one credit and a new balance are printed on the same horizontal line of the registration medium. As already explained, if there are more than two debits to enter, the sheet is advanced and, similarly, the sheet is advanced if there is more than one credit to be entered.



  The Read-scale, Read-uncovered, New scale and Soüs-total New scale keys cause the table to be automatically reset to the starting position (see fig. 1). When the Report-Balance or Report-Overdraft key is used in conjunction with the Balance to be carried over key, the amount of the old balance is printed in the Balance position again on the sheet.

   The Raise-scale and Raise-Discover keys also cause the table to be returned to its starting position, this position being the suitable position for writing the old scale.

   When one of the Balance statement or Bank statement keys is used to read old balances which are not to be printed on the new account statement sheet, the.

   Transfer scale key is not pressed together with this key, so that the old scale is transferred to the scale totalizer without being printed on the sheet. In other words, the Report Balance key is the printing key for the Read-Balance and Read-Overdraft keys, and pressing this Report Balance key in conjunction with these latter keys prints the old balance on the line called Balance again of the sheet.

      When an account is overdrawn, the New Balance key is locked to draw the operator's attention to the fact that the account is overdrawn. In this case, the operator has a choice of several possibilities. If you wish to clear the balance totalizer of this overdraft by printing the overdraft amount on the sheet, the Overdraft key (fig. 1) is pressed first to unlock the New Balance key, after which this key can be in the dark to perform a new balance operation;

   or, if the overdraft subtotal is desired, the Overdraft key is dark first to unlock the New Balance Subtotal key, after which this key can be pressed. A third possibility is to warn the customer that his account is overdrawn, by asking him not to give the bank a deposit in an amount sufficient to cover this overdraft; or, you can use the Correction checks key to cancel the entry of a number of checks already entered, of an amount sufficient to cover the overdraft.

      A sheet feeler device is provided to prevent the movement of the table out of the normal position, or starting position, under the influence of the row search keys, unless a writing medium is suitably put on the table. A mechanism for interlocking the line finder keys and the machine triggers is provided to prevent operation of the machine when a line finder button is partially pressed.

       <I> Built and </I> inecanism <I> command </I> The main frame of the machine comprises a left part 60 (fig. 4 and 5) and a right part (not shown) of similar construction. This frame supports most parts of the machine, and the two parts of this frame are connected to each other by a number of frames, rods and crossbars. Said parts of the frame rest on a base plate 61; this basic pla that 61 is fixed to four pressure frames by which it is supported.

   Three keys, these printing frames 62, 63 and 64 are shown in FIGS. 4, 5, 19 and 46. The printing frames are fixed relatively to each other by a front tie-rod 65 (Fig. 20, 26A and 26B), a middle tie-rod 66 and a rear tie-rod 67 and by a number. other bars, rods and trees. The pressure frames are also fixed to the upper surface of a sub-base (not shown), and the mechanisms of the machine are enclosed in a case 68 (Figs. 4 and 48).



       Normally, the machine is operated electrically by means of a motor; there is also provided a crank (not shown) for the hand control of the machine in case this is necessary. The machine is started by pressing any of a number of operator keys, described later in detail, of the totals control row and the transaction row.



  The depression of any one of the operating keys subjects a key locking shaft 69 (fig. 4 and 31) to the action of a spring (not shown) which causes this shaft to tilt a short distance in. the dextrorsum direction to actuate the clutch mechanism which connects the engine to a main shaft 70 (fig. 4 and 5) journalled in the main frame 60. The depression. an operator key activates at the same time the mechanism -a switch to close the motor circuit, thus starting the motor.

   Once the machine has executed the desired number of cycles, for a determined type of operation, the key locking shaft 69 is returned in the senestorsum direction, so as to disengage the clutch mechanism and simultaneously open. the electric motor switch. When the machine is operated by hand, the operating keys trigger the machine in a manner fully consistent with the operation by electric means.



       Keyboard. Referring to fig. 1, which is a schematic view of the keyboard, it will be seen that there are nine rows of upright keys 71 and two rows of check count keys 52 and 72. These keys are similar in many respects to the keys of my tants 71, except that they have their own addition wheels on the totalizer line N 1, to count the number of checks entered during the updating of an account.

     The machine is provided with a totals control plate 73 (fig. 6) to effect the engagement and disengagement of the two pendant totalizer lines. the operations of addition, subtraction, printing of totals and printing of subtotals. The setting of this totals control panel is effected by a number of totaLix control keys (fig. 1) numbered 74 to 78 inclusive and placed on the right side of the keyboard. The total control keys 74, 75 and 78 are operator keys and are used to set the. my machine running.



  The present machine is provided with two totalizer key lines which are selected and engaged with the amount drivers, using keys of a row of transaction keys (fig. 1 and 5) located near keys of transaction keys. order totals and numbered from 79 to 84 inclusive; all of these keys are operator keys.

   In addition to the operator keys 79 to 84, the row of transactions also includes a Space key 85 to effect the key advancement movement of the table carrying the writing medium; a Discovery key 86 to unlock the New scale 74 key when the totalizer -of the scales contains an overdraft, and an Unblock-deco-Llvert key 87 to unlock the Raised-Overdraft 79 and Raised-scale 84 keys when the totalizer contains any amount.

   Once an old scale has been read and saved by the machine, by pressing the Raised-Overdraft 79 or Raised-scale 84 key, these keys are locked and cannot be pressed until a new Line has been entered. which ensures that an old ba lance is raised only once. The Unlock-uncovered key 87 unlocks these keys in the event that it is necessary to use keys 79 and 84 more than once. Key 81 relates to: Deposits >>.



  In the normal case, the Report & Covered keys 79 and 84 are not printing keys; however, in the event that it would be advantageous to print the old scale, a Carry-over scale key 88, in the totals key row, can be pressed in conjunction with these keys to print the year. this balance on .the Balance line to be transferred from .the sheet. A recall key 89 is provided for releasing the Postponement balance key which is not released automatically at the end of machine operations.

   The Space key 85 is an operator key, like the transaction keys 7 9 to 84.



  To the left of the transaction keys is a row of symbol keys comprising ten keys 90 for printing identification symbols next to items inscribed under the influence of the transaction keys. Normally, the symbol keys 90 do not automatically return to their starting position; however, a recall key 91 placed at the top of this row of keys is provided for the release of these keys.

   The NC symbol key is depressed in conjunction with the Checks key 82 in cases where it is not desired that the item to be charged to the account is simultaneously charged to the automatic check counter. In other words, the NC key, which means not counted, disengages the mechanism of the automatic check counter, while at the same time printing the NC symbol next to the debit, or @ of the check, which was not counted.



  The monthly service charge is subtracted from any customer's account by entering the amount of such charge on the amount keys 71 and pressing the Checks key 82. When the service charge is subtracted from the account, a key symbol SC 90 is pressed in conjunction with the Checks key 82 to print, next to the amount of the bank service charge, the symbol SC (Service Charge) and at the same time disengage the automatic check counter , so that this item is not counted.



  All of the symbol keys 90, except the NC and SC keys, are simply printing keys for printing identification symbols alongside the corresponding items. For example, the IN (Interest) key prints the IN symbol next to the interest amount. The LS (Symbol List) key is dark when a single entry represents the total amount of a bundle of checks, the LS symbol being printed next to this amount.

   When the total amount of a bundle of checks is entered in this way, the number of checks in the bundle is dialed on the check counter keys 52 and 72 to record that number in the check counter wheels. Depression of the keys 52 and 72 to .compose the number of checks in a bundle disengages the automatic check counter.



  The position occupied by the Recall 91 key of the symbol keys (fig. 1) is also an automatic position used to automatically print the EC symbol, indicating Error correction. This operation is carried out by pressing the Deposit correction key 80 or the Check correction key 83. A Key recall lever 02 (fig. 1), at the far right of the keypad, unlocks all the keys except for those which do not return to their starting position after being knocked down; namely the symbol keys 90 and the Balance transfer key 88.

   The way in which the total control keys 74 to 78 inclusive control the selection of the different totalizers will be detailed below in connection with the description of the totalizers.



  It is well known how the totals control keys 74 to 78 inclusive and the totals control board 73 (Fig. 6) control the engagement and disengagement of the two lines of totalizers. Rows <I> keys </I> amount <I> and </I> their mechanisms <I> differentials. </I>



  The nine rows of post keys 71 and the differential devices associated with these keys are identical in all respects and are similar to well known mechanisms. Considering the similarity of the rows of upright keys, the description of one of these rows and of the associated differential mechanism will be sufficient to understand all of these rows.



  Fig. 4 is a cross section of the machine taken to the right of one of the rows of upright keys, showing the upright row and its differential mechanism. This row and mechanism will be described as representative of all rows of upright keys.



  The post keys 71 are carried by a key frame 93 supported by rods 94 and 95 which pass from one side of the main frame 60 of the machine to the other. Depression of any one of the upright keys 71 causes a zero stop pawl 06 of this particular denomination to swing in the senestorsum direction, carrying it out of the path of a zero reset spider 97 on the hub of a driver 98 of the differential mechanism of the uprights, pressed on and rotating in a bearing 99 extending between two similar plates 100 (only one of which is shown here),

   the plates being in turn supported on rods 101 and 102 extending between the two parts of the main frame 60. A pair of bearing plates are provided for each post differential mechanism, and a tie rod 103 passes through. openings at the centers of the bearings 99 to form a compact unit with all the differential mechanisms of the uprights.



  A notch in the anterior end of the spider 97 is engaged with a pin 1.04 of the anterior extension of an angled lever 105 pivoted on an extension of the trainer 98. The angled lever 105 and another angled lever 106, swiveling also on the extension of the trainer 98, serve. assembly to support a differential lock 107 capable of horizontal displacement. A spring 108 drives the bent levers 105 and 106 and the latch 107 backwards, so as to normally hold a foot-shaped extension 109 of this latch engaged with the shoulder 110 of a segment of the latch. drive of the differential mechanism 111, pressed and rotated on the hub of the driver 98.

   A connecting rod 112 pivotally connects the drag segment 111 to a cam lever 113 pi voting on a stud 114 carried by the left plate 100; this lever also carries rollers 115 and 116 which are in engagement respectively with the peripheries of two cams 117 and 118 fixed on the main shaft 70. The depression of any one of the upright keys 71 brings the lower end of the shank of this button on the path of a rounded surface 119. of an extension of the elbow lever 105.



  During the addition operations, the main shaft 70 and the cams 117 and 118 rotate in the dextrorsum direction, thus forcing the lever 113 to tilt the drag segment. <B> 111 </B> first in the dextror- sum direction and then. Back to its normal position according to the distribution shown in line 1 of the graph in fig. 47.

   The dextrorsal movement of segment 111 causes segment shoulder 110, in engagement with extension 109 of latch 107, to carry latch and driver 98 dextrorally until the surface rounded 119 comes into contact with the rod of the upright key 71 pressed. This swings the elbow levers 105 and 106 in the senestorsum direction to disengage the extension 109 from the shoulder 110, thus preventing the dextrorsum movement of the driver 98, and positioning the driver according to the key. upright 71 pressed.

   The movement of the latch 107 out of engagement brings a rounded extension 120 of this latch into engagement with the corresponding notch of a series of notches 121 in a plate 122 mounted between the rod. <B> 101 </B> and an upward extension of the left support plate 100.



  After releasing latch 107 from shoulder 110, an arcuate surface 125 of segment 111 moves to face extension 109 to hold the latch in position.



  When the lever 113 has reached the limit of its movement in the dextrorsal direction, a roller 126 carried by this lever comes into contact with an arcuate surface 127 of a pendulum 128 pivoted on it pin 129 provided in the driver 98, and brings a concave surface of the upper edge of this balance in contact with the hub of the driver 98 to position the balance, according to the depressed upright key.



  The balance 128 (fig. 4) has a notch 130 engaged with a pin 131 .a connecting rod 132; the upper end of this connecting rod pivots on an alignment segment 134 mounted on a tube of a series of telescopic tubes 135, mounted on a shaft 136 rotated in the main frame 60. The lower end of the connecting rod 132 is articulated to a segment 137 idle on a shaft 138 journalled in the frame 60. The segment 137 carries a stud 139 engaged in a cam notch of a cam plate 140 of the mechanism for eliminating the impression of zeros.

   This plate pivots on a pin 141 of toothed segment 142 mounted loosely on a shaft 143 journaled in the main frame 60. The teeth of the segment 142 mesh with the outer teeth of an outer-inner gear 144 (fig. . 4, 6 and 22).

   The internal teeth of this gear are engaged with the periphery of a disc 145 fixed on a shaft 146 carried by supports 147 fixed to a transverse bar 148 and to the frame of the machine, forming a rotary support for this gear 144. fia bar 148 (fig. 6) is fixed to the main frame 60 of the machine. The internal teeth of the outer-inner gear 144 (Fig. 4) are engaged with it pinion 149 rotating in an opening made in. the disc 145, and fixed to a square shaft 150.

    The pinion 149 and the square shaft in turn drive pinions 151 (FIG. 22) similar to pinion 149, which drive outer-inner gears 152 corresponding to this designation. The outer teeth of these grained wheels drive character wheels 153, idle on 1m shaft 154 supported by supports 147 (fig. 6). Provision is made for a character wheel and a control device for each of the columns of the sheet in which an amount will have to be printed.



  The control of the character wheels by means of outer-inner gears is well known. The plate 140 (Fig. 4) has a pin 155 engaged in a notch provided in the end of a drive slide 156 for the elimination of zeros. This slide. has two parallel notches respectively engaging with a shaft 157 journalled in support pieces 158 fixed to the base plate 61, and with a rod 159 held by arms 160 (only one shown) fixed to the shaft 157.

   A spring 161, tensioned between segment 137 and plate 140, normally holds the lower end of the plate cam notch in engagement with pin 139 as shown in FIG. 4.



  The zero deletion device shown here is similar in construction and function to well known key zero deletion mechanisms. An abridged description of this device, as shown in FIG. 4, will therefore suffice for an understanding of the operation of this device.



  Slider 156 carries a roller 162 which engages with the arcuate surface 163 of an idle control arm 164 on a shaft 165 twisted in the brackets 158. The arm 164 is attached to a idle hub on the shaft 165. , which connects it to an arm 167 engaged with a stud 168 of the arm 164 for the lower denomination. Likewise, the arm 164 for the denomination described herein has a stud 168 which engages with the arm 167 of the upper denomination, and so on.

    The pin 168 of the arm 164 for the highest denomination engages with an arm similar to the arm 167 attached to the shaft 165, so that this shaft is tilted first in the dextrorsal direction at the beginning of the operation. ration of the machine, and then back to the normal position.

   The dextrorsal movement of the shaft 165 and the arm 167 of the highest denomination is communicated by the pin 168 to the arm 164 of that highest denomination, and so on through the whole series of denominations, to make finally tilt the arm 164 shown here .first in the dextrorsum direction to move the slide 156 backwards, which releases the notch of this slide from the stud 155 carried by the cam 140.



  Suppose that one of the keys of the row of uprights shown in fig. 4 is depressed, which causes a rearward movement of the slide 156 to release the slide from the stud 155. The driver 98 is positioned under the influence of the depressed key 71. The roller 126 engages with the arcuate surface 127 to position the balance 128, the connecting rod 132 and the segments 134 and 137 in correspondence with the upright key pressed.

   Before positioning the segment 134 in the manner described above, an alignment device 169 (fig. 4), fixed to the shaft 170 journalled in the main frame 60, is tilted in the dextrorsun direction for bring it out of engagement with teeth 171 of segment 134; after the positioning of this segment under the influence of the balance 128, the alignment device 169 is brought into engagement with the teeth 171 to maintain the segments 134 and 137 against any displacement.



  The positioning of the segment 137 brings an arcuate surface 172 of this segment on the path of a roller 173 carried by the arm 164 for the denomination in question. As a result, the forward return movement of the slider 156 under the influence of a spring 174 is prevented, and the slider is retained in its rear position. The stud 168 of the arm 164 for the denomination shown in FIG. 4 prevents the return movement in the senestorsum direction of the arm 164 for the lower denomination, and so on down the line, to retain the slides 156 for all the lower denominations in their rear positions.

   As a result, the notches in these sliders are retained out of engagement with the studs 155, so that no movement is imparted to the cam plate 140 when the shaft 157 and the arms 160 are tilted in the senestorsum direction. and returned to the normal position after positioning, as explained above, the segments 137 under the influence of the depressed upright keys.



  When no key 71 is pressed, the row of amount keys shown in fig. 4 or of a row of a higher denomination, the segment 137 is positioned at zero, as shown here. In this position, a released part of this segment is located vis-à-vis the roller 173, so that the spring 174 can bring the arm 164 and the slide 156 forward, the notch in the end of the slider re-engages pin 155, after which shaft 157 receives movement in the senestrorsum direction, along with arms 160 and slider 156.

   The movement in the senestorsum direction of the slider 156 causes the cam plate 140 of the zero impression eliminator to reverse in the dextrorsum direction, so that the notch of this plate engages with the stud 139 , kept motionless during this time, to tilt segment 172 in the senestrorsum direction against the tension of spring 1.61, causing gear 144 in the dextrorsum direction out of the zero position into the position next, which in this case is a non-printing position.

   The movement in the dextrorsal direction of the gear 144 (fig. 4 and 22) causes a similar movement of the gears 152 corresponding to this denomination, by means of the pinions 149, the shaft 150 and the pinions 151 The character wheels are driven in the senestorsum direction out of the zero position shown in fig. 22 to a non-printing position, so that the zeros in the row of amount keys shown in fig. 4 are not printed. It is obvious that the printing of zeros will be eliminated in a similar manner in all higher denominations.

   In other words, the mechanism for removing the printing of zeros is activated when a key 71 is pressed in row 5 of the amount keys (Fig. 1) to effect printing of zeros in the four denos. lower minations and deletion of zeros in the four upper denominations.



  When the differential driver 98 of the uprights has been put into position under the influence of the depressed upright key 71, as explained above, the wheels of the selected totalizer engage with the corresponding gear of the two. gears 175 and 176 of the driver, whereupon the return movement of cam lever 113 and segment 111 brings the arched surface 125 of the segment past the foot of extension 109 of latch 107 to allow latch , under the influence of the spring 108, to fall behind the shoulder 110 to disengage the rounded extension 120 of the latch from the notch 121 of the plate 122.

   At the same time, a larger surface of segment 111 engages with nui stud 179 of the trainer 98, to bring the trainer back in senestrorsum direction, at the same time as <B> the </B> segment, towards the zero position. This movement in the senestorsum sense of the trainer 98 rotates the wheels of the totalizer or totalizers engaged, in proportion to the value of the key of my count 71 pressed, to make the addition or subtraction in the totalizer or the totals. - readers, of the amount represented by the amount key 71 pressed.



  If none of the upright keys 71 are depressed, the zero stop pawl 96 remains in the path of the spider 97; the initial movement of the spider and driver 98 forces the pawl to engage with a prolongation of the spider, which causes the latch 107 to come out of the zero position, after which the roller 126 engages with the spider. pendulum 128 to position segments 134 and 137, tan say that an associated proportional mechanism resets the character-bearing wheels 153 (fig. 22) of this row of keys to zero.



  At the end of any operation, the drive 98 (fig. 4) is returned to the starting position as shown here; however, connecting rod 132, segments 134 and 137 and the printing mechanism controlled by these organs are not reset. their starting position; they go directly to their new position for the next machine operation.

   The conventional transfer mechanism is provided to transfer the numbers of tens of lower denominations to higher denominations in addition and subtraction operations. <I> Totalizers. </I>



  As has already been explained, the machine shown has two lines of totalisers; namely an upper line called N 1, and a rear line called N 2. The totalizer N 1 is a balance totalizer, often called a balance; it comprises two series of wheels plus 180 (fig. 4 and 17) and minus 181 for the different denominations. The plus and minus wheels for each denomination mesh with each other, so that they turn in opposite directions. The balance totalizer is mounted on a frame 183 (FIG. 4) capable of being moved, this frame being mounted in the main frame 60.

   The frame 183 of the balance totalizer carries a shaft 184 (fig. 4 and 12) at the ends of which are fixed rollers 185 which engage with such milar guide slots made in two movable cam plates 186 (only one shown here) (fig. 12) respectively attached to the two right and left parts of the main frame 60. Similar cranks 187 are attached to the opposite ends of the shaft 184; these cranks carry rollers 188 respectively engaged in similar notches 189 made in the two cam plates 186.

    The right crank is articulated at one end of an engagement rod 190, the other end of which carries a stud 191 which engages with a corresponding hook of an engagement spider 192 rotating on a fixed stud 193.



  A movement is communicated to the engagement cross-groove 192 by a totalizer engagement slide 194; a notch in an anterior extension of the slide engages a stud 195 of an idle cam plate 196 on a fixed stud 197. Plate 196 has a notch 198 connected by a stud 199 to an approximately vertical notch 200 prevails in one of the arms of a caliper 201 also pivoting on the stud 797. The stud 199 is mounted on the upper end of a connecting rod 202, the lower end of which is articulated to a crank 203 fixed to a shaft. uncoupling of the zeros 204 (fig. 5).

   Another arm of the caliper carries a stud 205 which engages a cam notch of the totals control plate 73 (Fig. 6); this notch is not shown here.



  The way the totals control plate 73 controls the movements of the caliper 201, and the way the zero decoupling shaft 204 controls the. crank 203 which brings the slide 194 into engagement with the pin 192 are well known. Consequently, we will only give here a general description of this mechanism.



  A rearward extension of smooth neck 194 is hinged to the top end of a cam lever 206 slack on a fixed stud 207. Lever 206 (Fig. 12) carries a roller 208 engaged in a pin. cam groove 209 provided in one of the faces of a cam 210 fixed to the shaft 70.



  The movement of the connecting rod 190 to effect the engagement of the stud 191 with the hook of the spider 192 is carried out in the addition operations by mutilated control discs already well known; these disks are in turn controlled by the transaction keys, while the engaging movement of the connecting rod is effected, with regard to the totals and sub-totals printing operations, by one in check mark in the totals control plate 73 (fig. 6) in the usual way.



  When the totals control plate 73 is in the add position, a notch 211 of the slide 194 engages a stud 212 of the spider 192 as shown in FIG. 12; when the pin 191 engages the hook of the cross-groove 192, the lever 206 is driven by the cam-groove 209 to move the slide backwards or to the right, according to the distribution shown on line 4 of the graphi clue of fig. 47,

   which turns the cross 19'2 in the dextrorsal direction. This movement of the spider causes the crank 187 and the shaft 184 also to tilt in the dextrorsum direction under the influence of the connecting rod 190, so that the rollers 188, engaged with the notches 189, move the shaft 184 and the shaft 184. totalizer frame 183 (fig. 4) to bring the 180 or 181 series of balance totalizer wheels, depending on the series selected, into engagement with the coaches 98.



  As already explained, the engagement (the set of wheels with the coaches, in the addition and subtraction operations, does not take place until these coaches have been put in position as a result of the pressing of an upright key 71. The return movement in the senestror- sum direction of the coaches rotates the selected wheels in relation to the upright keys pressed, so that the amount entered on the keypad is recorded by these wheels.

   After the return movement in the senestorsum direction of the coaches 98, the cam 210 (fig. 12) brings the slide 194 forward to return the spider <B> 1.92 </B> in the senestrorsum direction, which brings the wheels of the tota liser of the scales out of engagement with the coaches 98.



  In the subtotal printing operation, the totals control plate 73 (fig. 6 and 12) moves from the add position to the subtotal position according to the distribution shown in line 3 of the graph of fig. 47.

   This movement of the plate communicates to the zero decoupling shaft 204 (fig. 5) an initial movement in the dextrorsum direction, thus preestablishing a condition in which an additional movement in the dextrorsum direction will be communicated to this shaft. during the subtotal operation. The initial movement in the dextrorsal direction of the shaft 204 brings the stud 199 down relative to the notches 198 and 200;

   however, this downward movement of the stud is limited by the curved portion of the notch 198, so that the notch 211 of the slide 194 remains in engagement with the stud 212 as shown herein.



  As already explained, the main shaft 70 and the cams attached to this shaft are given two turns in the dextrorsum direction during the printing of rates and sub-totals operations, and one revolution in the operations of. addition and subtraction.

   During the first revolution of the cam 210, the groove 209 causes the lever 206 to swing in the dextrorsum direction. to move the slide 194 rearward, thereby engaging the wheels of the selected tiller in engagement with the upright draggers prior to their initial dextrorsal movement; the drivers are held at the zero position during the first cycle of the total or subtotal print operation. This first printing cycle is used to perform the lateral displacement of the totalizer lines, in order to select the series of wheels necessary for the read or reset operations, as the case may be.

   During the second print cycle, the drivers 98, during their initial forward movement, drive the wheels of the selected totalizer rearward until the long teeth of these wheels secure the wheels in the wheel. zero position to position the post 98 coaches according to the value recorded by these wheels.

   When the drivers 98 are in the position corresponding to the amount recorded by the totalizer, the roller 126 (fig. 4) engages with the rocker 128 to bring the segment 137 and the printing mechanism into the position corresponding to the amount accumulated in the wheels of the totalizer.



  In the sub-total printing operation, when the slide 194 has completed its initial rearward movement to engage the selected totalizer wheels with the upright drivers, additional movement is imparted to the post. the ar ber 204, so that the stud 199, in conjunction with the cam notches 198 and 200, communicates to the plate 196 a movement in the dextrorsal direction to release the notch 211 from the stud 212,

   so that the wheels of the selected totalizer are not released from the drivers 98 at the end of the first cycle of operations. During the operation of printing a subtotal, the notch 211 thus remains clear of the stud 212 until almost the end of the second cycle of operations.

   Consequently, the wheels of the selected totalizer remain in engagement with the draggers during their return movement in the senestorsum direction to return these wheels to their original positions. After the reset of the wheels of the to talisator, that is to say towards the end of the second cycle of operations, the shaft 204 is returned in the senestorsum direction to put the notch 211 in engagement with the stud 212, so that the forward return movement of the slide 194, which occurs towards the end of the second cycle of operations,

       comm-only a return movement in the senestrar- siun direction to the spider 192 to put the wheels of the selected totalizer out of engagement with the coaches 98.



  In the printing of totals, or resetting the totalisers, the movement of the totals control plate from its addition position to its reset position communicates to the shaft 204 a movement. initial in the dextrorsum direction in an entirely analogous manner to subtotal printing operations. The totals control plate engages with stud 205 to tilt yoke 201 and plate 196 dextrorsum.

   The slide 194 is also tilted in the senestorsum direction: by the pin 195, so that the notch 211 of the plate is taken out of engagement with the pin 212. Towards the end of the first cycle of the printing operation of the to rate, and after the rearward movement of the slide 19-1 under the influence of the cam 210, an additional movement in the dextrorsiun direction of the shaft 204 forces the pin 199, in engagement with the cam notches 198 and 200, to tilt the plate 196 again over a distance in the dextrorsum direction,

       to engage a notch 213 of the slide 1.94 with a stud 214 carried by the spider 192. When the notch 213 engages the stud 214, the return movement of the lever 206 moves the slide 194 forward to give the engagement spider 7.9'_ 'a movement in the dextrorsum direction, so that the wheels of the selected totalizer engage with the drivers 98 at the end of the first cycle. In the second cycle, trainers reset these wheels to zero in exactly the manner specified for subtotal or read operations.

    While the wheels of the totalizer are at zero, and before the return movement in the senestorsuin direction of the coaches 98 (fig. 4 and 12), an initial movement of the cam 210 in the second cycle of operations moves the slide 194 towards the rear to communicate a disengagement movement in the senestrorsum direction to the spider 192, which puts the wheels of the selected totalizer out of engagement with the coaches and resets the wheels to zero.



  After the spider 192 has been returned to its normal position following a turn in the senestrorsum direction, and before the forward reverse movement of the slide 194, the shaft 204 is brought back partially back in the senestrorsum direction for forcing the stud 199 to return the plate 196 a sufficient distance in the dextrorsum direction to put the notch 213 out of engagement with the stud 214.

   When the slide 194 is thus disengaged from the engagement spider 192, the cam 210 returns the slide forward to its normal position, after which the return movement of the caliper 201 and of the plate 196 in the senestorsum direction. engages the notch 211 with the stud 212 in the manner shown in FIG. 12.



  A pawl 215 (fig, 12), controlled by a notch-cam 216 of the plate 196, engages it with notches 177 and 178 of the cross 192 during the printing operations of totals and sub-totals, of so that the spider is held stationary while the slide 194 is brought out of engagement with the studs 212 and 214. The roses 180 and 181 of the balance totalizer (fig. 4) are hand held against any movement in their disengaged position by an alignment device 236 driven by cams 237 (only one shown), fixed to the shaft 184.



  The rear row N 2 of totalizers (fig. 4 and 17) has two addition / subtraction totalizers, one for the accumulation of check keys and the other for the accumulation of deposits. It is necessary to provide addition / subtraction totalizers in these two cases, given the key necessity to provide a key means of correcting checks and deposits. The addition / subtraction totalizer for check accumulation comprises addition 217 and subtraction 218 wheels meshed to rotate in opposite directions to each other: analogously to the wheels of the scale totalizer No. 1 described above.

    The deposit totalizer includes addition 219 and subtraction 220 wheels similarly geared. Apart from the addition and subtraction totalizers, line N 2. Totalizer comprises a series of addition wheels 221 for the accumulation of new definitive plus scales and a series of addition wheels 222 for the accumulation of new definitive minus scales.



  In the operations of new balance, and if the totalizer. of scales contains a plus amount, the plus side of this totalizer is reset to zero and the amount transferred at the same time to the wheels 221; if the scale totalizer contains a negative amount, the wheels minus 181 are reset to zero and the amount carried by these wheels is transferred at the same time to the wheels 222 of the totalizer line N 2. This totalizer line N 2 is mounted in a movable frame 223 (fig. 4, 12 and 14) similar in all respects to the frame 183 of the balance totalizer, this frame carries a shaft 224 similar to the shaft 184 of the balance totalizer.

   The two ends of this shaft 224 carry rollers 225 (Him alone shown) which engage in guide notches made in cam plates 226, controlling the engagement (read totalizer, mounted on the inner side of the main frame 60 , as shown in Fig. 16. Engaging cranks 227 (only one shown) are attached to both ends of shaft 224, each crank carrying a roller 228 engaged in a cam slot 229 of the corresponding plate 226. <I> transfer of totals. </I>



  Since it is advantageous to transfer amounts from the balance totalizer to the two addition totalizers on line N 2 during new balance operations, it is necessary to provide a means other than the normal totalizer engagement device. , to control the engagement and disengagement movements of row N 2 of totalizers. This mechanism is shown in fi-. 12 to 16 inclusive.



  The engagement crank 227, mounted at the left end of the shaft 224 seen in the direction of FIG. 16, is connected by a hub 230 to an arm 231 having at its lower end a notch 232 (FIG. 14), in which a pad 233 is fixed to a stud 234, this stud being fixed in a movable plate 235 of which one forked part is pledged with -Lin hub 238 loose on shaft 224 (fig. 13).

   Stud 234 goes to. through the plate 235, and its upper end carries a roller 239 which. is normally held in engagement with a notch of a plate 240 integral with the hub 238, by a spring 1241 held in tension between the plate 235 and a stud of the arm 231. One end of an engagement rod 241 swivels on plate 240; the other end of this connecting rod carries a flattened stud 242 engaged with a notch provided in a hook-shaped projection 243 of the spider 192 (Figs. 12 and 13).



  The connecting rod 241 for the totalizer line N02 is controlled analogously to the connecting rod 190 for the totalizer line N 1 in the addition and subtraction operations, by selection discs, in turn controlled by the control keys. transactions. In totals and sub-totals printing operations, this link is controlled by the totals control plate 73, so as to ensure the engagement of the pin 242 with the notch in the hook 243 of the cross groove. engagement 192.

   Under normal conditions, the roller 239 remains in engagement with the notch of the plate 240 to connect this plate to the arm 231, which is in turn connected to the crank 227 and to the shaft 224; under these conditions, the row N 2 of totalisers receives its engagement and disengagement movements via the engagement spider 192 in a manner analogous to the mode of engagement of the: row of totalisers N 1.

   However, in new balance operations, it is necessary that the total accumulated in the balance totalizer is transferred to the uui of addition totalisers 221 or 222 (fig. 17.) of the totalizer line N 2. during the new ba lance operation. In order to transfer these totals, a means of passing has been provided: the control of the movement for engaging and disengaging the line N 2 of totalisers, from the spider 192 to the cam 210.

   As a result, this line of totalisers is engaged and cleared in the addition period, that is to say, as will be seen with reference to line 4 of the graph of FIG. 47, in the period represented by the timing of the cam 210.



  The bearing 233 (fig. 14 and 16) is engaged with a V-notch 244 of one of the arms of a bracket 245 on a pin 246 fixed in the right part of the frame 60. The other arm of the The bracket 245 carries the lower end: of a connecting rod 247 (fig. 12, 14 and 16) pi voted on this arm. The upper end of this connecting rod pivots on one of the arms of an elbow 248 idle on a shaft 249 fixed to the main frame 60.

   A spring 250 drives the crank lever in the senestorsum direction to engage a roller 251 attached to the other arm of the crank lever with a cam surface 252 on the periphery of the totals control plate 73 (see also fig. 6).



       When the totals control plate 73 is in any position other than that of the new scale, the roller 251 engages a concentric portion of the surface 252 (see fig. 12) and holds the plate 235 in its normal position. (Fig. 13) from above, in which position the roller 239 engages with the notch of the plate 240; this plate is controlled by the spider 192, as has already been explained.

   As the totals control plate moves from the new scale position, a protrusion 253 (Figs. 12 and 14) formed on the cam surface 252 engages with the roller 251 to swing the lever 248 and the caliper 245 in the dextrorsum direction. The dextrorsal movement of the caliper 245 moves the pin 234 and plate 235 downward to bring the roller 239 out of engagement with the notch in the plate 240, and to engage this roller 239 with a notch in. <B> U </B> 290 (fig. 15 and 16) provided: in a semi-circular block 254 fixed to one of the faces of an engagement arm 255 loose on the shaft 224.



  The arm 255 is connected by a connecting rod 256 to an idle crank 257 on the rod 102; this crank 257 has a notch which engages with a stud 258 of another crank 259 fixed to a hub 261 idle on a stud. 260 of the frame 60. Also fixed to the hub 261 is an arm 262 having a notch 263 engaged with a stud 264 fixed in an extension of the cam lever 206 (FIG. 12); it will be remembered that this cam lever is tilted in the dextrorsum direction and brought back to the normal position, during the addition time, by the cam 210.

   When the lever 206 is in the starting position shown in fig. 12, an extension 265 of the arm 255 is held in engagement with the stud 246 to align the notch in <B> U </B> 290 with the roller 239.



  Movement of the totals control plate 73 to the new balancing position brings the roller 239 into engagement with the notch 290, after which rotation of the cam 210 switches the lever 206 first in the dextrorsum direction. , to communicate a movement in the senestrorsum sense to the. plate 255 by means of the connecting members shown in fig. 15 and 16.

   This movement in the senestrorsum direction is communicated by the pin 234 to the arm 231., to the level 227 and to the shaft 224, so that the series of addition wheels selected, on the line N 2 of totalizers , is engaged with the up drivers 98 in the addition time, while the scale totalizer is being engaged with these drivers in the reset time.

   When the amount contained in the balance totalizer has been transferred to the series of addition wheels 221 or 222 (fig. 17) selected according to the character, positive or negative, of the amount in question, the cam 210 continues to operate. turn to return the lever 206 in the senestrorsum direction to release the line N 2 of totalizers.



  Whereas the main shaft 70 (fig. 12) and the cam 210 receive two turns during the new balance operations; it is obvious that the row N 2 of totalisers will be subjected to an engagement and disengagement movement during each revolution of the cam 210. However, this does not in any way prevent the proper operation of the machine, because the coaches 98 remain in the zero position during the first revolution of this shaft 70 and of the cam 210.



  When the totals control plate 73 leaves the new scale position to assume any other position, under the influence of the totals control keys, the projection 253 on the cam surface 252 of this plate disengages the roller 251, thus allows the spring 250 to return the elbow 248 and the bracket 245 (fig. 12 and 14) in the senestrorsum direction to drive the plate 235 and the pin 234 upwards, thus releasing the roller 239 from the 'notch 290, after which the roller re-engages with the notch in the periphery of plate 240.

    When the plate 235 (fig. 13 and 14) receives movement in the senestrorsum direction under the influence of either the plate 240 or the arm 255 (fig. 15), the stud 234 and the bush 233 disengage from the notch in <B> V </B> 244 of the caliper arm \ .345. Spring 1241 prevents plate 235 and stud 234 from moving when the stud is disengaged from notch 244 in caliper 245, and this spring holds roller 239 in engagement with notch in plate 240.

    When the roller 239 is in mesh with the in.- size in <B> U </B> 290 of the arm 255, an arcuate surface 266 of the plate 240 prevents the roller from coming out of engagement with the notch 290 when the pad 233 is disengaged from the notch. <B> V </B> 244 of the caliper 245. A stud 267 (Fig. 13) of the arm 231 engages with a shoulder of the plate 240 and helps the plate to impart an engaging motion to the shaft 224 and to the frame of the totalizer line N 2, and also helps. retain the plate 240 in its starting position, or normal position, shown here.



  The lateral displacement of the totalizer N 1, that of the scales, in order to bring the plus or minus side of this totalizer into engagement with the upright coaches, occurs under the influence of a transposition cam 268, shown schematically in fig. 17. Lateral movement of row N 2 of totalisers to select the plus or minus side of the two addition / subtraction totalisers and the two addition totalisers of this row N 2 occurs under the control of a control cam. transposition 269, shown in diagrammatic form in FIG. 17.

   The two cams 268 and 269 are maintained in a fixed relationship to each other, and the positioning of these two cams is controlled by the transaction keys 79 to 84 inclusive. <I> Transaction keys and </I> differential mechanism- <I> associated with these keys. </I>



  The way in which the cams 268 and 269 (fig. 17) are placed in position by the differential mechanism associated with the buttons. transactions is well known. A short description will be given here of this mechanism, with reference to FIG. 5.



  All the transaction keys, with the exception of the Overdraft 86 (fig. 1) and Unlock - Overdraft 87 keys, command the setting of the transaction differential shown in fig. 5. However, only the Deposits 81, Deposit correction 80, Checks 82 and Check correction 83 keys are effective, during check entry operations, to select their corresponding sides of the two addition / subtraction totalisers of the row. of totalizers N 2.

   As has already been explained, the two addition totalisers, of line N 2, for the accumulation of new positive and negative balances, do not come into contact with the trainers of my team during the registration operations. checks, but only during new balance operations to accumulate the amount of the new balance. The differential transaction mechanism controlled by the transaction keys selects the totalizers of row N 2 corresponding to the keys pressed, and also selects the side of the scale totalizer to be engaged with the trainers.

   This differential mechanism also controls the. positioning of the character wheels to print, next to the amount entered, characters indicative of the type of operation in question.



  Depressing any of the transaction keys except keys 86 and 87 (Fig. 5) causes a zero stop pawl 271 out of the path of the anterior end of the transaction. a spider 272 rotating on a hub 273 carried by an arm 274 of the differential mechanism of the transactions; this hub 273 rotates on a stud 275 which extends between two identical support plates 276 (only one shown here), mounted on the rods 101 and 102.



  The front end of the spider 272 has a notch through which a pin 277 of a control arm passes. <B> 278 </B> a latch pivoted on the arm 274 of the differential mechanism. This arm, in cooperation with an arm 279 articulated in the same way to the arm 274, allows the horizontal displacement movement of a latch 280 of the transaction differential. The latch 280 has a projection in the form of a foot 281, this projection being held normally in engagement, by a spring, with a shoulder of a driving segment 282 of the transaction differential, attached to the stud 275. The segment 282 is connected by -a connecting rod 283 to a cam lever 284 loose on a stud 285 supported by the plate 276.

   The vier 284 carries rollers 286 and 287 respectively cooperating with the peripheries of cam plates 288 and 289 fixed to the main shaft 70.



  The depression of any one of the transaction keys, with the exception of keys 86 and 87, carries the lower end of this key on the path of a rounded extension 292 of the latch arm 278; at the same time, the zero stop pawl 271 is pulled out of the way of the crisscross 272. Operation of the machine forces the cams 288 and 289 to swing the lever 284 and the differential drive segment 282 first in the extrorsal direction according to the distribution indicated in line 2 (fig. 47).

   The shoulder of the segment 282, in engagement with the projection 281, carries the latch 280 in the dextrorsum direction integrally with the shoulder until the rounded extension 292 engages with the shank of the depressed key to tilt the arm 278 in the senestror- sum direction, releasing the projection <B> 281 </B> of the shoulder of segment 282 and putting a rounded extension 293 of the anterior part of this latch 280 in engagement with a corresponding notch 294 of an alignment plate 295 supported by the rod 101 and by the plates 276. These members determine the position of the differential arm 274 in correspondence with the transaction key which has been pressed.

    Continuing its forward movement, segment 282 causes an arcuate surface, formed on this segment, to engage with foot-like projection 281 to lock latch 280.



  When the lever 284 (fig. 5) approaches the limit of its initial dextror- sum movement, a roller 297 carried by lever engages a rounded surface 298 of a differential bay 299 articulated to the arm 274, for bring an arcuate surface of the upper edge of this balance in contact with a cut part of the hub <B> 273, </B> so that the balance is positioned in relation to the pressed transaction key.

   The balance 299 carries a fork engaged with a stud 301 carried by a connecting rod 302 whose upper end is articulated to. a segment 303 fixed to one of the tubes 135 of the shaft 136. The lower end of this rod is articulated to a segment 304 idle on the shaft 138 and connected by a rod 305 to a gear 306 fixed on shaft 143. Gear 306 engages the outer teeth of an outer / inner gear 307 rotatably mounted on a disk supported in turn by shaft 146. This gear 307 is attached to an annular gear 308 meshing with a pinion 309 attached to a shaft 310 spiraled in the supports 147.

   Other pins 309 (Fig. 6) attached to shaft 310 drag other external / internal gears similar to gear 307; these gears position character-carrying wheels for transactions; these wheels are placed so as to correspond to the various columns of the registration medium on which they print symbols indicative of the transaction in question. A toothed sector 311, engaged with a gear 312 idle on a stud 313 fixed in the base 61, is also fixed to the shaft 143 (FIG. 5).

   Gear 312 engages gear 314 attached to a shaft 315 journalled in the print frame; This shaft 315 positions selection discs which control the operation of the printing hammers and the movement of the writing support table. The mechanism of these disks will be described in more detail below in connection with the mechanism for positioning the table.



  The tube 135 (fig. 5), while being dragged by the segment 303, is connected to another segment (not shown) connected by a connecting rod to the cams 268 and 269 (fig. 17) for setting the totalizers. to position these cams in relation to the transaction key pressed.



  The numbers from 0 to 9 inclusive placed next to the horizontal lines in the schematic views of the selection cams of the totals 268 and 269 (fig. 1 and 17) correspond to the different transaction keys and to the positions of the transaction differential. . For example, the zero position corresponds to the automatic position indicated at zero.

   This position is automatically selected when the balance totalizer contains a negative amount, and the Uncover key 86. is used in conjunction with the New Scale 74 key to clear the scale totalizers, to print the new negative scale and to transfer this new negative scale to the new negative scale totalizer 222 (TNB-). The ninth position of cams 268 and 269 is also an automatic position, selected when the scale totalizer contains a positive amount;

   in this case, the New scale key 74 is used alone to empty the balance totalizer and to transfer this positive amount at the same time to the totalizer of new total scales plus 221 (TNB +) (fig. 17) in the totalizer line N 2. The Raised-uncovered key 79 also selects the first position of cams 268 and 269, but since this key does not communicate to any clutching and disengaging movement at line N 2 of totalizers, the wheels 222 of the new scale total less are not engaged with the coaches of my students.

   The same is true with the Lift-balancing button 84, which selects the ninth position of cams 268 and 269, but since the Lift-balance button does not communicate an engagement and disengagement movement to line N 2 totalizers, the wheels of the new total scale plus are not engaged with the upward rollers when this key is pressed.



  In other words, it is necessary to use the New Scale 74 key to select one or the other of the new scale totalizers and to engage and disengage these totalizers relative to the coaches. amount.



  When the. New balance key 74 is only pressed, it chooses the new total balance wheels plus 221; when the New Scale key is used in conjunction with the Overdraft key 86, for example when the scale totalizer has an overdraft, the combined action of these two keys automatically selects the wheels of the new total scale minus 222 , and these wheels are subjected to an engagement and disengagement movement relative to the upright drivers.



  In other words, when the totalizer of the new phis total scale is selected as a result of pressing the New scale key 74, the engagement cams 268 and 269 are automatically set to the ninth position, that is to say say the position where the plus side of the totalizer N 1, or totalizer of scales, is emptied; this ninth position also selects the new total balance totalizer plus 221 for the addition operation necessary to transfer the amount plus from the balance totalizer to the new total balance totalizer plus.

    Likewise, when the new total scale minus totalizer is selected by pressing the New Scale key 74 and the Open key 86, the cams of. selection 268 and 269 are reset; the minus side of the scale totalizer is selected, this side is emptied, and at the same time the new total scale minus totalizer is selected for the addition operations necessary to transfer the total minus from the scale totalizer to the new totalizer total balance minus. The Deposits key 81 (fig. 1 and 17) corresponds to the fourth position of cams 268 and 269.

   Pressing this key forces cam 269 to choose @the plus side of totalizer N 3, or deposit totalizer (+ 3D) on the line. <B> NI ' </B> 2 totalizers. Depression of this key also forces cam 268 to select the plus side of totalizer N 1 or balance totalizer, so that the amount of the deposit is added to the amount contained in this totalizer.



  When the deposit correction button 80 (fig. 1) is used to correct an error, the differential mechanism of the transactions puts the cams 268 and 269 in their second position; in this position, the cam 269 chooses the wheels minus the totalizer N 3 of the deposits (-3D); these wheels are brought into engagement with the upright drivers, and at the same time, cam 268 selects the minus wheels of the balance totalizer, so that the deposit amount is subtracted from the two totalizers.



  When the Checks key 82 (fig. 1) is used during check writing operations, pressing this key puts cams 268 and 269 in the sixth position (fig. 17); in this position, the cam 269 chooses the plus wheels of the check totalizer N 2 (-2C) of the line N 2 for the accumulation of the total amounts of the checks; at the same time, cam 268 selects the negative side of the balance totalizer to subtract the check amount therefrom.

        When it is necessary to make a correction in the entry of a check, the key. Check correction 83 (fig. 1) is used. This key places cams 268 and 269 in eighth position (fig. 17). In this position, cam 269 selects the minus side 218 of check totalizer N 2 (-2C) and forces cam 268 to select the positive side of the scale totalizer, so that the canceled check amount, which represents a credit, be credited to the check totalizer <B> N </B> 2 and also to the balance totalizer.



  The Space key 85 (fig. 1) causes the differential mechanism of transactions and cams 268 and 269 to be placed in third position; however, it will be seen, with reference to FIG. 17, that this position is a zero position for the cams 268 and 269.

   However, this movement of the transaction differential is used to control the writing medium table space in a manner which will be described in more detail below. As already explained, the Discovery keys 86 and Unlock-Discovery 87 are short keys; they do not position the transaction differential and do not release the zero stop pawl for this differential, so that this differential remains in the zero position when one of these keys is pressed.

           Mechanism <I> of the </I> plate <I> of </I> command <I> of </I> totals.



  Referring to fig. 6, it will be remembered that the normal position of the totals control plate 73 is the add position, that is, the position suitable for addition and subtraction operations. In these operations, the transaction keys control selection discs, to bring the different totalizers of lines N 9 1 and 2 into engagement with the upright drivers.

   However, in printing totals and sub-totals operations, it is necessary to use the totals keys 74 to 78 to select the different totalis lines for the engage and disengage movements. . The use of the New scale key,> was explained in detail above with regard to the transaction keys.



  The Subtotal New Scale key >> 75 (fion-. 1) places the totals control panel 73 in a position for reading or sub-totalizing the scale totalizer. The Transaction Subtotal key 76 is a non-operator key;

   it is used in conjunction with the Checks key 82 and the Deposits key 81 to select the addition / subtraction totalizers 2C and 3D of row N 2 of the totalizers (fig. 1,7), for read or sub-total operations - lization. Said key 76 is also used in conjunction with the Read-Balance 84 and Read-Overdraft 79 keys to select the new total balance plus and new total balance minus totalisers of line N 2 of the totalisers,

       when it is advantageous to read said totalizers.



  The Total transactions key 77 is also a non-operator key; it is used in conjunction with the Check 82 and Deposit 81 keys to reset the 2C and 3D addition / subtraction totalizers to zero, and also, in conjunction with the Relevé-bajlance 84 and Relevé-Découvert 79 keys, to reset the totalizers of the new total scale to zero. plus and .of the new total balance minus of line N 2 of the totalisers.

   The Total old balance key 78 is an operator key used to reset the totalizer N 1, that of the scales, to zero at the end of a series of balance transfer operations. In this connection, said key functions in a manner analogous to the New scale key 74, except that said key 78 does not cause the selection of the totalizers of the new plus scale / new scale minus scale for the totals transfer operations, like the New Balance key 74.



  It will be remembered that the Balance transfer key 88 (fig. 1) is not an operator key and does not control the setting of the totals control panel 73 (fig. 6). It is used in conjunction with the RL-Balance 84 and RL-RL 79 keys to print under the New Balance heading, the amount of the old balance.



  We will remember that in the way. the New scale key 74 forces the totalizer to add new scales. positive totals 221 (TNB +) (fig. 17) or the totalizer of the new negative total balances 222 (TNB-) to engage with the upright drives during the addition time during the new ba lance a. been explained previously with respect to the mechanism of FIGS. 12 to 17 inclusive.



  Apart from the selection of the totalizers for the addition, reading and resetting operations, the setting of the control plate - totals 73, under the influence of the total keys 74 to 78 inclusive , by means of the mechanism shown in fig. 6, controls the setting in position of the character-carrying wheels of the totals corresponding to these keys, for the printing of the identification symbols next to the totals and sub-totals.



  The totals control plate 73 (fig. 6) is connected by a connecting rod 316 to an elbow lever 317 fixed to the shaft 138; this elbow lever 317 is also connected by a connecting rod 318 to a loose gear 319 on the shaft 143. The grit 319 is engaged with the outer / inner gear 320 supported, so as to be able to turn, by a disc on the shaft. 'shaft 146, in a manner fully consistent with gear 144 for the row of uprights shown in. fig. 4.

   An annular gear 321, integral with the gear 320, engages with a. pinion 322 fixed to a shaft 323 journaled in the supports 7.47. The outer teeth of gear 320 engage with a totals and subtotals character wheel 324, causing this idle wheel to spin on shaft 154.

   Shaft 323, in cooperation with similar pinions at pinion 322, and with gears similar to gears 321 and 320, sets other character wheels to totals and. Subtotals in position, in relation to the position of the totals control plate 73, to effect the printing of identification characters in the various columns of the sheet.



  Attached to the shaft 138 (fig. 6) is a toothed sector 325 in mesh with a gear 326 idle on the stud 313; this gear 326 in turn engages with a gear 327 on the shaft 315. The gear 327 is fixed to a gear 328 in mesh with a gear 329 fixed on a shaft 330 (fig. 4) journalled in the frame printing.

   The mechanism just described communicates the positioning of the totals control plate 73 to the shaft 330 and puts the selection discs, idle on the shaft 315, in position according to the position of. the totals control plate, so that the discs can control the printing and sheet feeding members in a manner which will be described in detail hereinafter.



  The outer / inner gears attached to shaft 146 (fig. 4, 5 and 6) and the character wheels positioned by these gears are held against movement by an alignment device 331 attached to a shaft 332 journaled in the gears. supports 147, and the usual device is provided for disengaging this alignment device 331 during the positioning of these external / internal gears.



       Mechanism <I> from the table of </I> registration support ,. A movable table 335 (fig. 19 and 48) is provided at the front of the machine to carry the inscription support 343 or 344 (fig. 2 and 3) to the printing members. The table is capable of being positioned at any one of 39 row positions, i.e. the number of rows of the heel raised sheet 343 and 344.

   The appropriate row for printing the first item during a write-in operation is always selected by pressing one of the appropriate row-finder keys, after which the table setting is fully automatic and not does not require operator intervention. In the case of registering an account, the final operation is always an operation (I new balance, during which the table is released automatically to return to its original position, where the sheet can be removed from the machine.

           When. the first entry is made on the thirty-ninth and last row, the table is released automatically and returned to its original position. If it is necessary to make subsequent entries on this row, the row-finder keys 39 must be lowered to make the selection of said row for each item thus entered, since the table is automatically set to the original position after registration of each item.



  When there is a question of a registration transaction, it is understood that the said transaction comprises several machine operations, during which the old balance is raised, the debits are subtracted from the said balance, the credits are therein. added, and a zeroing operation is performed to establish a new balance. A detailed description will now be made of the mechanism of the sheet support table and associated mechanisms. Table 335 is conveniently placed at the front of the machine (fig. 1.9, 20 and 48).

   Said table is carried by rails 336 and 337, so that it can move sideways on the rails and between upper 338 and lower 339 rollers mounted on the printing frames 62 and 63. The opposing edges rails 336 and 337 engage without play in frames 62 and 63 to prevent excessive lateral movement of table 335. Table 335 has three openings 340, 341 and 342 (Figs. 19 and 22), so that the Printing hammers, during their printing movement, can bring the sheet and the ink ribbon in contact with the type wheels to effect the printing of the various articles on the sheet. <I> Device for positioning and </I> retained <I> of the sheet. </I>



  The sheets 343 and 344, shown respectively in FIGS. 2 and 3, are placed on the table 335 between guide bars 345 and 346 at both sides of the table (Figs. 19 and 48); the leaves are pushed backwards or upwards, as shown in fig. 19, until they engage a number of stops 347 attached to table 335.



  During the movement of the upper edge of the sheet engaged with the stops 347 (fig. 19, 20 and 21), this upper edge passes between two pressure blocks 348 and 349 carried by pressure arms 350 and 351, each of which has two bent arms loosely attached to a tree <B> 352 </B> rotating in two supports 353 and 354 fixed to the upper face of the table 335. Two dragging arms 357 and 358 of the pressure blocks, fixed at the opposite ends of the shaft 352, are resiliently connected to their -respective pressure arms 350 and 351 by torsion springs 359 and 360 kept under tension between the studs of the arms 357 and 358 and the arms 350 and 351.

   Referring to Figs. 20 and 21., the first being a profile projection seen from the left side of the machine and the other being a profile projection seen from the right side of the machine, it will be seen that the springs 359 and 360 force their respective arms 350 and 351 to engage with the upper surface of the driving arms 357 and 358. Slots are made in the table 335 to admit the arms 350, 351, 357 and 358.



  An arm 361, likewise attached to the shaft 352 (fig. 19 and 21), extends through an opening 362 of the table 335. This arm is dragged in the direction of the extrorsum by a res sort of torsion 363 maintained. under tension between the arm and the table, so that a roller 364 carried by the arm is normally kept in contact with one end of a lever 365.

   The lever 365 is pivoted on a stud 366 of a plate 367 forming part of the printing frame, and this lever is driven in the senestorsum direction by a spring 368, to normally maintain a roller 369 carried by the lever in engagement with the periphery of a cam plate 370 fixed to a shaft 371 journalled in the printing frame. The shaft 371 is driven on one rotation in the dextrorsum direction by one cycle of operation of the machine, in a manner which will be described in detail below.

   It will be seen that, when the table 335 is in the starting position, shown in FIG. 21, the roller 364 is in contact with a shoulder formed on the plate 367, and which serves to lock the table in its starting position. The initial movement of the cam 370 causes the lever 365 to swing in the dextrorsiun direction to lower the arm 361 and the shaft 352 in the senestorsum direction against the action of the res sort 363,

   and this movement in the se nestrorsum direction is communicated by the arms 357 and 358 and by the springs 359 and 3606 to the pressure arms 350 and 351 to force the pressure blocks 348 and 349 to resiliently squeeze the count sheet-343 in contact with the upper surface of the table 335, so as to hold the sheet against any displacement from its proper position.



  As explained above, the starting position of the table is the position suitable for printing the balance again (fig. 2 and 3) on the line provided for this purpose immediately above the first line of the sheet. For this reason, the pressure blocks 348 and 349, controlled by the cam 370 and the lever 365, retain this sheet during the registration of the balance again.

   A senestrous movement of arm 361 (Fig. 21) under the control of cam lever 365, brings roller 364 out of engagement with the shoulder of plate 367 to align it with horizontal surface 372. of the upper part of said plate 367. When said table 335 is moved rearwardly from the starting position, under the influence of the table setting device, described in detail below, the roller 364 is carried on the horizontal surface 372 to retain the pressure blocks 348 and 349 in engagement with the sheet when said table 335 is moved to any of its 39 different row positions.

   At the end of the new balance operation and certain other operations, the table is brought forward to the starting position, while the spring 363 (fig. 19 and 21) drives the arm 361 and the shaft 352 in the dextrorsum direction, causing roller 364 to come into contact with the shoulder abutting surface 372 to disengage pressure blocks 348 and 349 and to lock table 335 in the starting position. Mechanism <I> of </I> command <I> of the table. </I> Referring to fig. 19 and 20, we will find a series of rectangular holes 373 and 374 made near each of the edges of the table 335.

   Said orifices are of equal size and spacing, so that the solids between the orifices form, so to speak, rack teeth which are respectively engaged with similar gears 375 and 376 mounted on a shaft 377 journalled in the print frame. Likewise, the rack teeth formed by the orifices 373 and 374 are respectively engaged with similar gears 378 and 379 respectively mounted on one of the ends of sleeves 380 and 382, supported so as to be able to rotate by means of studs 383 and 384 fixed respectively in the frames 62 and 63.

   Gear 378 (Fig. 19) carries a stud 385, which is engaged by one end of a coil spring 386 as loosely rolled around the circumference of sleeve 380, the other end said. spring being arranged in such a way that it engages with a pin of a flat 388 plate on the sleeve 380. The plate 388 forms the pivot of a pawl 389, driven in the senestrorsum direction to engage with the teeth of a ratchet 391 fixed on the stud 383.

   Similar members, namely a spring 392, a plate 393, a pawl 394 and a ratchet 395 are provided for the gear 379 (Figs. 19 and 20). The mechanisms just described constitute a spring-actuated device for driving the table 335 constantly forward, said device also serving to return said table to the starting position of any one of its 39 line positions.

   The ratchets 391 and 395, in cooperation with their pawls 389 and 394 and their respective plates 388 and 393, form a winding or tensioning means of the springs 386 and 392 to ensure that the table Q35 is returned properly to its position of departure after being released from any of her line positions. It is obvious that the springs 386 and 392 are also useful in maintaining the table in the starting position.



  * <I> Indicator </I> the <I> table. </I>



  Uri flag is intended to give a visual indication of the row number to which table 335 has been positioned. This mechanism comprises a gear 396 (Figs. 20 and 46) engaged with and driven by gear 379, said gear 396 being fixed to one end of a short shaft 397 journalled in a bearing 398 fixed in the frame. 63. Attached to the other end of shaft 397 is a disc 399 attached in turn to the face of a drum 400 forming an indicator. The flanged part of the drum 400 carries, engraved on its circumference, the letters BF and the numbers from 1 to 39 corresponding to the different line positions of the table 335 and of the sheet.

   The letters BF and the numbers are visible through an opening in a cover (fig. 48) attached to the printing frame. When the table 335 is in the starting position, as shown in fig. 46, the letters BF standing for Balance to be transferred are visible through the opening of the cover.



  An auxiliary control shaft 402 of the table is aligned with the axis of the shaft 377 (Figs. 19 and 46) hereinafter referred to as the main control shaft of the table 335. Said auxiliary shaft 402 is journaled in the frames 63 and 64, and the positioning of this. auxiliary tree is controlled by the row finder keys, in a manner which will be described below.

   Attached to gear 376, which is attached to shaft 377, as previously explained, is gear 403 and bevel gear 404, the latter being connected by two pinions 405 to an attached bevel gear 406. in turn to a positioner 407 pivoting disc with gear 406 on shaft 402. Pinions 405 rotate on a pin 408 mounted in auxiliary drive shaft 402. Identical gears 404 and 406 and their coupling pinions 405 form a planetary or differential gear for coupling the auxiliary drive shaft 402 with the main shaft <B> 377. </B>



  A gear 409 integral with a conical gear 410 is mounted idle on the shaft 402 (FIGS. 25B, 26B, 27B and 46). Said bevel gear 410 is connected, by means of a bevel gear 411 idle on a pin 412 fixed in the shaft 402, to a bevel gear 413 fixed to a gear 414 idle on the shaft 402.

   The differential mechanism comprising the identical bevel gears 410 and 413 and their coupling pinion 411 forms a device for transmitting the value of the pressed line search keys to the auxiliary shaft 402, and the positioning of said auxiliary shaft is communicated by the differential mechanism, namely the gears 404, 405 and 406, to the main shaft 377, for the. establishment of the. table 335 proportionally to the value of the row search keys pressed.



       Complementary slides for <I> the keys </I> line finder. The gear 414 (fig. 25A, 25B, 27A and 27B) meshes with the teeth of a 1st rack provided on the upper edge of a main slide 417 sliding horizontally by means of a flat surface 418 at its part. lower in cooperation with a rod 419 supported on the frames 63 and 64 and by means of a horizontal notch 420 provided in the front part of said slide,

   cooperating with a rod 421 supported in the same way on the frames 63 - and 64. A plate 422 carrying rack teeth - is fixed to the slide 417; said rack teeth are engaged with a pinion 423 which also meshes with teeth of a similar plate 424 attached to an auxiliary slide 425 mounted next to the main slide 417 and capable of lateral sliding by means of a flat surface of its lower part in cooperation with the rod 419 and by means of a notch similar to the notch 420 cooperating with the rod 421.

   Pinion 423 is mounted on a stud 426 which extends through parallel notches 427 in sliders 417 and 425, and the opposite ends of said stud 426 engage with similar notches in similar arms 428 and 429 which straddle them. slides 417 and 425, said arms being linked together by a hub 430 idle on a rod 431 supported on frames 63 and 64.



  A crank 432 is attached to the hub 430 (Fig. 25A, 25B, 27A and 27B). Said crank is fixed with the arms 428 and 429 and, in co-operation with said arm 429, it supports an idle pin 433 on a slide 434 sliding in a slot 435 of a connecting rod 436 articulated with an idle cam lever 437 on a rod 438 resting on the printing frame. Rollers 439 and 440, mounted on the cam lever 437, respectively engage with the peripheries of cam plates 441 and 442 attached to the camshaft 371 of the printing mechanism.

   Compression springs 443 and 444 stretched between the slider 434 and the ends of the slot 435 form a damping connection between the stud 433 and the connecting rod 436. The sliders 417 and 425 respectively have removable plates 445 and 4.46 with steps 447 and 44.8, which engage with the lower parts of the rods of nine line finder keys of units 449 (fig. 25A, 28, 29 and 30) mounted in a frame 450-supported by rods 451 and 479 supported on the printing frame.



  When any of the unit row 449 keys are depressed, the dextrorsum - movement of shaft 371 and cams 441 and 442 during machine operations causes lever 437 to move the lever. connecting rod 436, crank 432 and arms 428 and 429 forward or in the dextrorsal direction according to the distribution indicated on line 12 of the graph (fig. 47).

   The coupling pin 423 of the slides 417 and 425 moves forward integrally with the arms 428 and 429, while taking said slides 417 and 425 to. that steps 447 or 448, corresponding to the depressed units key 449, come into contact with the end of the depressed key. The other slider moves independently of the slider which has already been put in position until the two sliders are put in position in proportion to the line search key pressed. This movement of the slides 417 and 425, under the influence of the arms 428 and 429 and of the pinion 423, constitutes what is called the action of the complementary bucket slides.

      The complementary movement of two organs coupled in this way is well known. While the combined motion of the coupled members is the same, the motion of one of said members is likely to vary relative to the motion of the other; it is this variation that is used to communicate the value of the pressed row search keys to table 335.

      The movement of the slide 417 by means of the rack teeth carried by said slide engaged with the gear 414 (fig. 25B and 46), by the differential mechanism which comprises the bevel gears 410 and 413 and their coupling pinion 411, and in cooperation with the complementary sliders of the row search keys of the tens, causes the positioning of the shaft 402 in proportion to the pressed row search keys.



  To properly explain the operation of the complementary slides for the positioning of the table 335 in proportion to the pressed row search keys, it is necessary to move on to a description of the complementary slides for the tens keys, best represented at the end. <B> 26-11, </B> 26B, 27A and 27B.



  The tens line finder key mechanism comprises a main slider 452 and an auxiliary slider 453 mounted so as to allow horizontal movement, exactly. same way as the sliders 417 and 425 for the keys of the units, by means of flat surfaces at the lower part of said sliders 452 and 453 in cooperation with the rod 419 and by means of horizontal slots 454 at the front ends of said sliders in operation with rod 421.

   The slides 452 and 453, respectively, carry plates 455 and 456 provided with opposing rack teeth engaged with a pinion 457 forming a coupling means of said slides 452 and 453. The pinion 457 is mounted on a stud 458 which extends through slots 459 of sliders 452 and 9.53, and said stud also extends through similar arm slots 460 and 461, connected by a hub 462 loose on rod 431. A crank 463 is attached to hub 462 in fixed ratio with arms 460 and 461.

    Said crank, in cooperation with the arm 461, supports a stud 464 loosely engaged with a loose block 465 in a slot 466 at the front end of a connecting rod 467 whose rear end is hinged to an idle cam lever 468 on the rod 438. The cam lever 468 carries rollers 469 and 470 which engage respectively with the peripheries of cams 471 and 472 fixed to the camshaft 371 of the printing mechanism. Compression springs 4721 and 4731, compressed between the block 465 and the ends of the slot 466, establish a damping connection between this block and the connecting rod 467.

    The slides 452 and 453 (fig. 26A and 26B) carry removable plates 473 and 474 respectively provided with steps 475 and 476 which engage with the lower ends of three line finder keys 477 of the tens, mounted in a frame 478 supported by the rods 451 and 479. The depression of a tens line finder key 477 moves the lower end of the rod of this key, which comes on the path of the corresponding steps 475 and 4'76 of the slides 452 and 453.

   The rotation of the shaft 371 and of the cams 471 and 472 during the operation of the. The machine swings the cam lever 468 in the senestorsum direction to drive the forward. connecting rod 467, crank 463, arms 461 and 460 and pinion 457.

   This forward movement of the pinion 457 drives the sliders 452 and 453 of the pinion, exactly in the manner already described for the sliders of the units 417 and 425, until the grits of these slides come. in contact with the pressed key, which puts the sliders in proportional positions.



  The setting in differential position of the main slide 452 under the influence of the tens line finder keys 477 is transmitted, by the rack teeth provided at the upper edge of this slide, to the gear 409 ( Fig. 26A, 26B and 46) and to the auxiliary shaft 402;

   as a result, this tree is positioned in proportion to the expensive key in tens row 477 which has been pressed. After printing and towards the end of the operation of the. machine, the slides of units 417 and 425 and tens 452 and 453 are brought to zero, the position in which they are shown in fig. 25 <B> -A </B>, 25B, 26A and <B> 2613. </B>



  In the event that none of the line finder keys of units 449 (fig. 25A and 25B) are not pressed, a zero stop pawl 481., slipped on rod 421, cooperating with a pin 482 on main slide 417 , retains this slide at the zero position. As a result, the operation of the connecting rod 436 communicates full movement to the auxiliary slide 425 while the main slide 417 remains stationary, so that no movement is imparted to the gear 414 or to the shaft 402. .

   If no tens line finder key 477 is depressed (Figs. 26A and 26B), a zero stop pawl 483 for these keys, in cooperation with a stud 484 in the main slide 452, retains this slide. zero position;

   as a result, the full forward movement of connecting rod 467 caused by machine operation is communicated to auxiliary slide 453, while main slide 452 remains stationary, so that no movement is communicated to gear 409 nor to the auxiliary drive shaft 402.

   Depression of any one of the keys of the units 449 causes the zero stop pawl 481 out of engagement with the stud 482, while the depression of any of the three tens keys 477 toggles. the zero stop pawl 483 out of engagement with the stud 484 in a manner which will be discussed in detail hereinafter.



  For example, assume that one of the units 449 line finder keys has been darkened and none of the tens keys 477 has been pressed. In this case, the main slide 452 and gear 409 for those tens keys remain stationary, and the movement of the slide of units 417 in contact with the lower end of the key shank which has been pressed. This drives the gear 414, thus forcing the bevel gear 413 (fig. 46)

   driving the coupling pinion 411; but, as the bevel gear 410 is held stationary, the pinion 411 travels around the said bevel gear to rotate the pin 412 and the shaft 402 in the dextrorswn direction, as shown in FIGS. 25A, 25B, 26A and 26B,

      pro portional to the value of the 449 units key pressed. If a tens line finder key 447 has been pressed without pressing one of the units keys 449, the entry 414 remains stationary.

   In this case, the tens slider 452 and the gear 409 drive the shaft 402 in the dextrorsum direction in proportion to the value of the tens key pressed. When a 4.49 ones line find key and 477 tens key are pressed in a single operation - say 5 on 449 and 20 on 477 - to set the table 335 on line 25,

   the combined movements of the main sliders 417 and 452 are communicated by the gears 414 and 409 (see also fig. 46), by the differential gear comprising the bevel gears 410 and 413, the pinion 411 and by the pin 412 at. the shaft 402 to turn said shaft in the dextrorsum direction in proportion to the value of the keys of the dark units and tens.



  The differential position of the auxiliary shaft 402 under the influence of the line finder keys is communicated to the main shaft 377 by means of the differential gear (fig. 46) comprising the bevel gears 404 and 406 and the pinions 405. To transmit this movement to said shaft it is necessary to fix the disc 407 and the bevel gear 406 (fig. 39 and 46) stationary, in a manner which will be described below, so that said bevel gear forms a device for driving the pins 405, which are rotated around the axis of the shaft 402 by the pin 408 which is fixed, as will be remembered, in the shaft 402.

    Because bevel gear 406 is held in a fixed position at this time, the movement of auxiliary shaft 402 can be communicated by pinions 405 to bevel gear 404, gears 403 and 376 and to The main drive shaft 377 of the table 335, thus transmitting to this shaft a movement in the senestorsum direction, as shown in fig. 20, and in the dextror- sum direction, as shown in fig. 25A, 25B, 26A and 26B, in proportion to the value of the line finder keys pressed.

   Movement in the senestrorsum direction of shaft 377 (fig. 20) and gears 376 and 375 moves table 335 rearward to the row position corresponding to the pressed row seekers, so that the amount dialed on the amount keys is entered on the desired line of the sheet. <I> Ratchet locking the table. </I>



  A ratchet connected to the main shaft 377 holds the table in the position in which it was placed under the influence of the search-line keys. As already explained, after the selection of a row of the sheet by means of a row finder key, the movement of the table becomes fully automatic during the subsequent write operations, from one source to the next. manner which will be explained below.



  Referring to Figs. 43, 45 and 46, it will be seen that the gear 403 meshes with a gear 485 fixed to one end of a shaft 486 journalled in the frames 63 and 64. Also fixed to the shaft 486 is a gear 487. meshing with a gear 488 solidly connected to a table locking ratchet 489, a table advancement ratchet 490 and counter-boost key ratchets 491 and 492 of the table; all these components are attached to a hub 493 loose on the shaft 402. A retaining pawl 494 (fig. 38, 43 and 46), loose on the shaft 486, is driven in the dextrorsum direction by a spring 495 to be engage with locking ratchet 489.



  When the main shaft 377 is positioned by the search-line keys, as explained above, the gear 403 drives the gear 485, the shaft 486 and the gear 487 integrally in the senestorsum direction; this movement is communicated, by the gear 487, to the gear 488 and to the other organs, including the locking ratchet 489, integral with the gear 488, so that this gear and these organs are obliged to turn in the dextrorsal direction when considering fig. 43.

   The teeth of the ratchet 489, cooperating with the pawl 494, prevent any retrograde or return movement of the table 335 (fig. 19) under the influence of the springs 386 and 392, thus retaining the table in the position in which it has. been placed by the search line keys.



  It is now necessary to move on to the description of the device provided to hold the disc 407 (fig. 39 and 46) and the conical gear 406 stationary, so that the rotation of the auxiliary shaft 402, under the control search keys, is communicated to main shaft 377 and, therefore, to table 335. Disc 407 (Fig. 39) has a V-shaped notch 496 in mesh with a rusting worm lug 497 on a rod 498 supported by the printing frame.

   The lug 497 is connected by a hub 499 to a projection 500 which is driven in the dextrorsal direction by a spring 501 fixed to the tie rod 66, so that the lug 497 is normally kept out of engagement with the notch 496. The projection 500 has a hook 502 cooperating with a pin 503 provided in the front end of a rod 504, the rear end of which is articulated to a V-shaped lever 505 loose on the rod 438. The lever 505 carries rollers 506 and 507 respectively co-operating with the peripheries of cam plates 508 and 509 attached to the camshaft 371 of the printing mechanism.



  The forward end of link 504 is connected by a link 510 to the selector lever of a disc 511 idle on a shaft 512 journalled in the print frame. A res out 513 drives the lever 511 in the senestorsum direction to maintain a high surface of the lower edge of said lever in engagement with a stud 514 of an arm 515 slack on the shaft 512.

   The lever 511 has a rounded finger 516 able to cooperate with the periphery of a control segment 517 of the feeler mechanism of the sheet, mounted idle on the shaft 315.



  The arm 515 (fig. 39) carries an arm 897 connected by a connecting rod 898 to a cam lever 899 loose on the rod 438. A spring 900 drags the taras 515 and 897 in the senestrorsum direction and the connecting rod 898. and lever 899 rearwardly, such that a roller 901. carried by lever 899 normally engages the periphery of a cam 902 attached to camshaft 371 of the printing mechanism.

   The timing diagram of cam 902 is given on line 9 of the graph (Fig. 47); it will be seen that, immediately after the start of the operations of the machine, the projecting part of said cam descends from the roller 901 and from the point 903 of the lever 899, thus delivering the lever 899 and the members associated with the action of the spring 900, so that said members are driven immediately rearward: -arm 515 carries lever 511 by means of spring 513 to force finger 516 to engage with the periphery of segment 517.



  The rod 504 carries a pin 518 arranged to be engaged with the tooth of a latch 519 loose on the shaft 512, said latch being driven in the dextrorsum direction by a spring 520, so that in the normal case an extension upwardly of said latch is held in engagement with a stopper 521 attached to the lower surface of the table 335.



  As long as the table 335 is in the starting position shown in fig. 39.1a stopper 521 retains the tooth of the latch 519 out of engagement with the pin 518. However, when said table 335 is moved from the starting position, the tooth of the latch no longer impedes the movement of the lever 511;

   as a result, the stud 503 engages the hook 502, after which the operation of the cams 508 and 509, according to the distribution indicated on line 10 of the graph (fig. 47), causes the engagement of the lug 497 with the notch 496 in the form of <B> V of </B> disk 407, so that the auxiliary shaft 402 is coupled to the main shaft 377 to effect the positioning of the table 335 under the influence of the pressed row search keys.

   If the sheet is not properly placed on the table, or in the event that no sheet is placed on the table, a sheet scanning device described below forces the periphery of segment 517 to come in. the path of the finger pal fear 516 to prevent engagement of the stud 503 in the hook 502. Consequently, the pin 497 remains clear of the notch in the form of a <B> V </B> 496 of: disk 407, which prevents the setting in position of the table 335 under the influence of the search-row keys, the table thus remaining in the starting position.



  As the link 504 moves downward to engage the stud 503 with the hook 502, the stud 518 carried by said link drops and moves in front of an angular surface 522 of the latch 519 before the table 335 moves upward. right, when considering fig. 39, that is to say out of the starting position. The movement of the table 335 controlled by the line finder keys disengages the stopper 521 from the upward extension of the latch 519, thus allowing the face 522 to elastically engage the stud 518 under the influence of the spring 520. .

   After the table 335 has been placed in position under the influence of the row finder keys, the cam 902 returns the arms 897 and 515 and the lever 511 in the dextrorsum direction to release the pin 503 of the hook 502 from the projection 500 and to urge stud 518 over the latching surface of latch 519, such that said latch, under the influence of spring 520, passes below said stud 518 to impede any movement of engagement of the latch. link 504 and stud 503. As a result, pin 497 is prevented from re-engaging with the V-shaped notch 496 of disc 407 during the remainder of the recording operation to be performed. acts.

   Therefore, if, during this registration operation, the line finder keys are inadvertently or accidentally pressed, the movement of the auxiliary shaft 402 caused by the depression of said keys will be damped by means of the rotation to. empty of bevel gear 406 and disc 407, and will not be communicated to mainshaft 377.



       11 'feeler mechanism <I> of </I> da <I> sheet. </I>



  A feeler mechanism for the account statement sheet, shown in fig. 40 and 41, is provided for controlling the segment <B> 517 </B> (fig. 39) to prevent the positioning of the table 335 under the influence of the search-line keys. In the event that no record 343 has been placed on said table. This mechanism comprises a feeler device 525 moving vertically in that parallel notches are freely engaged on the shaft 377 and the rod 498. Collars attached to the shaft 377 and the rod 9:98 determine. the lateral position of the feeler device 525 on said shaft and on said rod.

   The feeler device 525 has a pin 526 engaged in a notch of one end of a lever 527 idle on a rod 52 $ supported by the printing frame. A notch on the opposite end of lever 527 is engaged with rod 529 connecting segment 517 (Fig. 39), hammer control segment 530 (Fig. 40), and other segments 531 (Fig. 22). for controlling the hammers or the printing mechanism, said members being all mounted freely on the shaft 315.

   Segment 530 (fig. 40) is connected by a connecting rod 532 to one of the arms of a cam lever 533 (see also fig. 41) slid on the rod 438. Another arm of the cam lever 533 supports a roller 534 co-operating with the periphery of a control cam 535 of the feeler device, fixed to the camshaft 371 of the printing mechanism. When the cam 535 approaches its starting position, at which it is shown in fig. 41, the roller 534 descends from a steep shoulder formed at the periphery of said cam, thus allowing a point 536 to engage with said shoulder to obtain a more rapid exploration action by the feeler device 525 than would be possible with roller 534.

   A spring 523 (fig. 40 and 41) drives the cam lever 533 in the senestorsum direction, so that the gait 534 and the point 536 are held normally in engagement with the periphery of the cam 535.



  Referring to line 18 of the distribution graph (fig. 47), it will be seen that immediately after starting the machine, the movement in the dextror sum direction of shaft 371 and cam 535 (fig. 40 and 41) moves the steep shoulder of said cam to beyond point 536, thus releasing lever 533 to the action of spring 523.

   By means of the coupling members shown in FIG. 40 and described above, the feeler device 525 is moved immediately upwards, so that an upward extension of said feeler device passes through an opening in the table 335 to look up a plug 343. If a plug 343 is suitably placed on table 335, the complete movement of the feeler device is prevented by said plug, which prevents movement in the senestorsum direction of segment 517 under the influence of spring 523.



       When the upward movement of the exploration device is prevented by a plug 343, means are provided for the immediate return of said device 525 and the associated members to their starting position. The tension of said device against the plug 343 is immediately released, which ensures the return to the normal position, shown here, of segment 517 (fig. 39), so that the arcuate surface of said segment does not come into engagement with it. the feeler finger 516.



  The return mechanism of the pal fear device comprises an elbow lever 537 (fig. 40) which is slid on the shaft 315. One of the arms of the elbow lever engages freely with the rod 529. The other arm of the elbow lever 537 is connected by a connecting rod 538 to a return disc 539 loose on the rod 438. The return disc 539 has a shoulder 540 cooperating with a return pawl 541 articulated to one of the arms of a cam lever 542 and driven. in the senestrorsum direction by a spring 543.

   A curved extension 544 of the pawl 541 resiliently engages a stud 545 of a support 546 supported by the rod 438 and by the shaft 371, so that said pawl 541 is retained away from the path of the shoulder. 540 when the lever 542 is in the start position as shown in Eig. 40. A spring 547 (Fig. 40) drives the lever 542 in the dextrorsum direction to maintain elastic contact between a roller 548 carried by said lever and the periphery of a cam 549 fixed to the camshaft 371.

   When said cam 549 is in the starting position shown here, the tension of spring 547 is sufficient to overcome the action of spring 543 and, therefore, to retain pawl 541 out of the path of shoulder 540.



  In the event that the complete upward movement of the feeler device 525 and the associated organs is prevented by the plug 343, the rotation of the cam 549 causes the lever 542 and the pawl 541 to tilt first in the senestorsum direction and then to the normal position, according to the distribution indicated on line 19 of the graph (fig. 47).

   When the lever 542 begins its initial movement in the senestorsum direction, the extension 544 of the pawl 541 is withdrawn from the fixed stud 545 to allow the spring 543 to support said pawl on the path of the shoulder 540. By turning further in the pin. direction senestr or sum, the lever 542 forces the pawl 541 to engage with the shoulder 540 and, consequently, to put back the elbow lever 537, the rod 529, the segment 517 (fig. 39) and the device. probe 525 in the normal or starting positions, shown here.



       When no plug 343 is on the table 335, the complete movement of the pal device 525 under the influence of the cam 535 is not prevented; therefore, this upward movement causes, by means of lever 527, rod 529, segment 517, and elbow lever 537 all their way in the senestrorsum direction to drive the arcuate surface of segment 517 into the path of the finger 516 (fig. 39). As a result, the movement in the senestorsum direction of the lever 511 is interlocked, which prevents the engagement of the stud 503 with the hook 502 of the projection 500.

   In this way, the lug 497 is prevented from engaging with the notch in the form of a <B> V </B> 496 of said 407. Therefore, said disc and tapered gear 406 are free to rotate, with the result that the positioning of the shaft 402 is the influence of the keys sought in the row. will not be transmitted to the feed shaft 377 of the table, which will therefore remain in the starting position.



  When the upward movement of the positive feeler device 525 is not hindered by a plug, the movement in the senestorsum direction of the bent lever 537, communicated by the connecting rod 538, causes the deflection disc 539 to tilt in the dextrorsum direction to move the shoulder 540 formed on said disc beyond the pawl 541. The pawl 541 is thus prevented from engaging with said shoulder 540 during the operation of the cam 549 and, consequently, the feelers will not be not returned to the normal position at the start of machine operation.

   In this case, the cam 525 (fig. 41), in cooperation with the roller 534, returns the lever 533 and the associated members, namely the segment 530, the elbow lever 537, the return disc 539 and the feeler device. 525, in the normal positions shown in fig. 40. The way in which segments 531 (fig. 22) impede the action of the printing hammers when no card has been placed on the table 335 will be explained below with respect to the check printing mechanism. .



   <I> Construction of </I> rows <I> keys </I> line finder. It will be seen, with reference to FIGS. 25A and 25B, that the duplicate search keys 449 are supported in frame 450, mounted on rods 451 and 479 in the print frame. Each of the keys of the units 449 has a projection 551 cooperating with a wedge 552, these wedges being freely mounted on a support 553 supported by studs 554 and 555 attached to the frame 450. The instructions for use of the tight wedges 552 in order to preventing more than one key from being pressed at a time is well known.

   When any of the keys of the units 449 is depressed, the projection 551 squeezes the corners against each other to prevent the depressing of a second key in the same row at the same time. 11. It is not necessary to describe this well known method of key locking in more detail.



  Referring to fig. 29, it will be seen that the searcher keys of units 449 are arranged in two groups, of which the right group comprises the even keys and the left group the odd keys. It will also be seen, with reference to FIG. 30, that the row finder keys of the units have projections 556 on their left side, analogous in all respects to projections 551 on the right side. It will also be seen that the right projections 551 of the even keys and the left projections 556 of the odd keys are longer than the corresponding projections of the keys of the opposite group.

    The long projections 551 of the even keys and the long projections 556 of the odd keys, in cooperation with compression springs 557 mounted on four fingers removed from the retainers 558 which are mounted on the frame 450, normally keep the keys 449 in place. the position no. pressed. The projections 556 of the keys of the units 449 cooperate with hooks 559 of a trigger 560 (Figs. 28 and 31) slidable through slots in cooperation with studs 554 and 555.

   A spring 561 drives the detent 560 rearward or to the right, when considering FIG. 28, so that an angular, cam-shaped ridge of hooks 559 is normally in contact with projections 556. The depression of any of the keys of units 449 (Figs. 25A, 28, 29) , 30 and 31) forces the projection 556 of said key, in cooperation with the angular surface of the corresponding hook 559, to move the trigger 560 forward or to the left, against the action of the spring 561.

   As the projection 556 passes past the hook 559, the spring 561 pulls the trigger 560 rearward to force the hook to pass over the projection, thereby locking the key in the depressed position. J1 should be noted that these keys are not elastic keys, that is, a pressed one cannot be released by pressing another key and so on, because the wedges 552 prevent sinking. more than one 449 key at a time. At the end of the machine operation, the trigger 560 (fig. 28 and 31) is automatically moved forward to unlock the units line search button which has been pressed.

   A manual means is also provided for moving the trigger 560 forward to unlock the depressed key 449 before starting the machine, in the event that a wrong key has been depressed. This manual means will be explained below. The short projections 551 of the odd keys 449 (Figs. 28 and 30) cooperate with angular surfaces of the projections 562 of a control bar 563 moving horizontally by means of horizontal slots cooperating with the studs 554 and 555,

         while the short projections 556 of the even keys 449 cooperate with like surfaces of like projections 564 of a like control bar 565 which also moves horizontally by means of slots carried by the bar and engaging with the studs 554 and 555. Similar springs 566 (Fig. 28) drive control bars 563 and 565 forward to keep the rear ends or right ends of horizontal slots in the bars in contact with studs 554 and 555.

   Similar control rods 563 and 565 (fig. 28 and 25A) have lower extensions 567 and 568 cooperating with a pin 569 of the zero stop pawl of units 481. This pawl is driven in the senestorsum direction by a spring 570 until it engages with a stopper 571, a position in which the hook of said stopper 481 is normally in the path of the square stud 482 of the main slider of units 417.



       The depression of one of the keys 449 (fig. 25A and 28) forces the projection 551 or 556 of said key, in cooperation with the angular surface of the projection 562 or 564 of the corresponding bar 563 or 565, to move. said slider rearwardly against the action of the spring 566, which causes the extension 567 or 568 of the slider, in cooperation with the pin 569, to swing the zero stop pawl 481 in the dextrorsum direction against spring tension 570.

   As a result, the hook of the zero stop pawl is moved away from the path of the square stud 482, so that the main slide is released for its forward movement and can be brought into position by the pressing button 449. When pressing button 449; is released towards the end of the machine's operation, the control bar 563 or 565 is returned to the front by the action of the spring 566, thus releasing the zero stop pawl 481 which engages with the stud 482 to reset the main slide 417 to zero during subsequent machine operations.



  The trigger 560 has a hanging finger 573 (fig. 25g, 25B, 27g, 27B, 28 and 30) cooperating with a stud 574 of a trigger bar 575 sliding by means of parallel slots 576 and 577 made in said bar in cooperation with rods 1420 and 421.

   A connecting rod 578 connects the bar 575 to a cam arm 579 idle on the rod 438; said arm carries a roller 580 cooperating with the periphery of a cam 581 for unlocking the keys, mounted on the camshaft 371 of the print. A spring 582 drives the cam arm 579 in the dextrorsum direction to normally maintain the roller 580 in contact with the periphery of the cam 581 and, therefore, to hold the bar 575 in its rear position, shown here.

   The rotation of the camshaft 371 in the dextrorsal direction during the operation of the machine forces a projection 583 formed on the cam 581, in cooperation with the roller 580, to tilt the arm 579 in the senes direction. - trorsum according to the distribution indicated on line 17 of the graph (fig. 47).

   The movement in the senestrorsum direction of the cam arm 579 drives the trigger bar 575 forward; during this movement, the stud 574 engages with the finger 573 to move the trigger 560 forward, or to the left in fig. 28 and 31, so that the hook 559 is released from the projection of the depressed key 449, thus delivering said key to the action of the spring 557, which immediately returns the key to the normal position.



  A manually operated device is also provided to move the bar 575 and to release the depressed units key 449.



  Referring to Figs. 25g and 27g, it will be seen that a slot in the anterior end of the trigger bar 575 engages a stud 584 of an arm 585 loose on a stud 586 fixed to the frame 64, the arm 585 being resiliently connected by a spring 588 with an arm 587 also loose on the stud 586.

   A projection 589 of the arm 587 is engaged with a downward extension 590 of a slider 591 moving vertically by means of vertical slots cooperating with studs 592 fixed in a plate 593 fixed to the frames 63 and 64. The upper surface of the slider 591 carries a trigger bar 594 mounted in the hand of the operator in front of the keys 449 and 477. A spring 595 retains the; bar and slide 591 in the starting position shown here.

   Depressing the trip bar 594 against the action of the spring 595 moves the bar and slider downward, thereby forcing the extension 590 to engage with the projection 589, causing the arms 587 and 585 to swing. in the sec- nestrorsum direction to move the release bar 575 forward. Stud 574 engages finger 573, thereby pulling trigger 560 forward to release the depressed unit key 449. The spring 588 constitutes a damping device protecting the bar 575 and the trigger 560 against any damage as a consequence of a too slow blow on the trigger bar 594.



  A device controlled by trigger 560 (fig. 25g, 28 and 31) is also provided for locking the machine if any of the line finder keys of units 449 is partially depressed. As he has. been already explained, the partial depression of one of the keys 449 forces the projection 556 of said key, in cooperation with the angular surface of the corresponding hook 559, j to move the trigger 560 forwards against of the action of the spring 561.

   This forward movement of the trigger 560 engages a vertical notch, forming the front part of a notch made in the tent, with a pin 596 of a crank 597 mounted on a shaft 598 journalled in the frame of 'impression. This causes a tilting in the dextrorsum direction of the crank and the shaft.

   A second crank 599 i is also fixed to the shaft 598; this crank rotates in the dextrorsum direction integrally with the shaft to tilt an elbow lever 601, to which it is connected by a connecting rod 600, in the dextrorsum direction, said. bent lever being pivoted at a fixed fulcrum 602. The bent lever 601 also has a pin 603 which engages with a foot-shaped extension of a connecting rod 604; a slot in said connecting rod engages with a fixed stud 605, while the upper end of the connecting rod is hinged to a crank 606 attached to a shaft 607 journalled in the left frame 60.

   The shaft 607 also carries a crank 608 connected by a connecting rod 60.9 to a latch 610 loose on a stud 611 fixed in the left frame 60. A spring 612 drives the connecting rod 604 downwards, which normally takes a notch. 613 of the latch 610 out of the path of a stud 614 of a machine release lever 615 attached to the key lock shaft 69.



  The dextrorsal movement of the angled lever 601 moves the connecting rod 604 upward, rocking the crank 606, shaft 607 and 1a. crank 608; this dextror- sum tilting is communicated to the latch 610 by means of the connecting rod 609, so that the notch 613 of said latch comes on the path of the stud 614 to prevent the release movement in the dextrorsum direction of the lever 615 and of the key lock shaft 69, therefore preventing operation of the machine when one of the keys 449 is partially depressed.

   Depression of any one of the line finder keys of units 449 all the way through allows the trigger 560 to return rearwardly under the influence of spring 561. Spring 612 rocks the trigger. latch 610 in the senestrorsum direction to move the surface 613 of the path of the stud 614 to allow the release of the machine. <I> Device </I> preventing <i> a </I> niouveme7at <I> excessive </I> table.



  A retainer under the control of the line finder keys is provided to prevent excessive displacement of table 335 when it is moved to the first print position by the members shown in Figs. 25A, 25B, 26A and 26p. The control bar 563, operated by the odd-numbered keys 449 (Fig. 28), has a slot in its rear end; the slot in the fork a pin 617 of an extension of a bracket 618 loose on the shaft 598.

   A curved part 619 of the caliper 618 is placed below an extension of a retaining pawl 620 (fig. 42), loose on the shaft 486, when the bar 563 is in its previous position. as shown in FIG. 28. Depressing one of the odd-numbered keys 9-49 moves the control bar 563 rearward (fig. 28), tilting the yoke 618 in the senestorsum direction to move the curved extension 619 out of the way. pawl 620 and to drive it in the path of a retaining pawl 621 loose on the shaft 486.



  The eliquet 620 engages with the retaining ratchet 491 (fig. 42 and 46) which comprises a number of teeth corresponding to the odd lines of the table 335 and of the sheet 3-13 (fig. 2 and 19), while that the pawl 621 engages with the ratchet 492 which has teeth corresponding to the even lines of the table 335 and of the plug 343. Downward extensions of the pawls 620 and 621 have similar slots 622 cooperating with a pin 623 provided in the front end of a connecting rod 624, the rear end of which is articulated to a cam arm 625 loose on the rod 438.

   A spring 626 drives the cam arm 625 in the dextrorsum direction so that a roller 627 carried by said cam arm is normally in contact with the periphery of a cam plate 628 in adjustable connection with a disc. drive 629 mounted on shaft 371. Springs 630 (Fig. 42) drive pawls 620 and 621 in senestorsum direction to hold the front ends of slots 622 in contact with pin 623.



  The timing diagram of cam 628 is shown on line 11 of the graph (fig. 47) and, comparing this diagram with that of cams 441 and 442 (fig. 25A and $ 25) controlling slides 417 and 425 which move table 335 to.

   row position corresponding to the depressed key 449, it will be seen that immediately before the table arrives at the selected row position, a point of the cam arm 625 falls from a steep shoulder of the cam 628 to allow the arm 625 to move the connecting rod 624 backwards, delivering the pawls 620 and 621 to the action of their springs 630, which immediately drive the pawl, the path of which is not obstructed by the curved extension 619 of the caliper 618.

   The pawl engages with the teeth of the corresponding ratchet 491 or 492, thus stopping the rotation of said ratchet, which rotates in the dextrorsum direction by means of the gears shown in FIG. 46, namely the gears 488 and 487, the shaft 486 and the gears 485 and 403 which are driven, as we will recall, by the shaft 377 which positions the table 335 so as to stop the table at the chosen row position.



  This retainer is particularly essential and effective when the table is moved to the higher number lines, for example to position 39. The movement acquired by the table during such a prolonged forward movement could very well drag it out. table in a position higher than the chosen position. When none of the odd-numbered keys 449 (fig. 28) is pressed, the caliper 618 remains in the position shown in fig. 42 to prevent the pawl movement 620. Therefore, the pawl 621 is effective in this case and cooperates with the ratchet 492 corresponding to the even lines, as already explained, to prevent excessive displacement of the table 335.

    When one of the odd-numbered keys 449 is dark, the yoke 618 is tilted in the senestorsum direction to bring the extension 619 on the path of the pawl 621 and to release the pawl 620. Therefore, said pawl 620 becomes effective after the machine start-up, to prevent excessive displacement of table 335 in cooperation with the teeth of ratchet 491 corresponding to the odd rows of table 335.



   <I> Keys </I> line finder <I> tens. </I>



  Referring to Figs. 26A, 26B and 29, it will be recalled that the keys 477 are used in conjunction with the keys of the units 449 to position the table 335 at rows greater than the ninth. If you want to choose the tenth line, key 10 is pressed alone, and this is the case for keys 20 and 30. The tens keys 477 are mounted so that they can slide into the key frame 478 next to the row of unit keys, said frame being supported by the rods 451 and 479.

   The construction of the tens row 477 is similar to that of the units 449; therefore, the following description of the row of tens keys is less detailed than that already given of the ones keys.



  Each of the tens keys 477 (fig. 26A, 29 and 30) has an extension 633 cooperating with a compression spring 634 attached to forked extensions of a retaining plate 635 fixed to the frame 478, said members serving to retain the keys in their raised position shown here. The depression of one of the keys 477 forces the extension 633 to trigger a trigger 637 forwards against the action of a spring 640.

    The movement of the trigger is effected by the extension 633 in cooperation with an edge of a corresponding hook 636 mounted on said trigger which is slidable by means of horizontal slots engaged with studs 638 and 639 in the. frame 478. When the extension 633 passes past the hook 636, the spring 640 withdraws the trigger 637 rearwardly, which brings said hook onto the extension 633 to lock the key 477 in the depressed position. Cam 581 (fig. 25A and 25B) drives the key release slide forward a little before the end of machine operation.

    The pin 574 is engaged with an extension 641 of the trigger 637 to move said trigger forward against the action of the spring 640. This releases the hook 636 from the projection 633 of the tens key. pressed 477, and the key is immediately returned to its starting position by the action of the spring 634 (fig. 30). The forward movement of the slider 575, caused by the manual release bar 594 also causes the pin 574 to move the trigger 637 forward to unlock the depressed tens key 477.



  Depression of key 477 (Figs. 26A and 29) engages projection 633 with a ridge of an upward extension 642 of control bar 643 sliding into frame 478 by means of slots engaged with. studs 638 and 639; therefore, the control bar 643 is moved rearward. This rearward movement of the control bar 643 brings a downward extension 644 of said bar in contact with a stud 645 mounted on the zero stop pawl 483 for key 10 477. Said pawl is tilted in. the dextrorsum direction against the action of a spring 646 to move a notch carried by said pawl away from the path of the square stud 484 provided on the main slide 452 for the tens keys.

   Depression of key 477 (Fig. 26A) causes projection 633 to engage with a ridge of an upward extension 647 of control bar 643, which moves said control bar rearward to release. the zero stop pawl 483 as shown above. Depression of either key 20 or key 477 brings the projection 633 of the key into contact with the ridges of the upward extensions 648 and 649 of a control bar 650, mounted in the frame 488 in such a manner. to be able to slide thanks to slots cooperating with the studs 638 and 639.

   This causes rearward movement of the control bar 650, during which a downward extension 651 of the control bar, in cooperation with the stud 645, moves the zero stop pawl 483 out of the path of the stud. 484 to allow the positioning of the main slide 452 of the material indicated above.



  Depression of key 10477 brings extension 633 into the path of a projection 655 of control bar 650. Rearward movement of the control bar being prevented in this way, extensions 648 and 649 prevent the depressing of the keys 20 and 30 477. Similarly, the depressing of the key 20 477 causes extension 633 of this key on the path of a projection 652 of the control bar 643 to prevent movement. towards the rear of this bar, so that the extensions 642 and 647 of the control bar, in cooperation with the extensions 633 of the keys 10 and 477, prevent the depression of these keys.

    Depression of key 30 477 forces the extension 633 of this key, in cooperation with the cam surfaces of the extensions 647 and 649, to drive the control rods 643 and 650 backwards, so that the projection 652 of the control bar 643 passes below the extension 633 of the key 477, to prevent the depressing of this key. The projection 655 similarly passes below the extension 633 of the key 477, to prevent the depression of this key.



  When the trigger 637 (fig. 26A) is moved forward under the influence of a partially depressed key 477, a notch of a rearward extension of the trigger engages with a pin 653 of a crank 654 fixed to the shaft 598. It follows that this crank and this shaft are tilted in the dextrorsum direction to carry the latch 610 (fig. 31) on the path of a pin 614 to prevent the unlocking movement of the key release shaft 69.

    When key 477 is depressed all the way, trigger 637 is returned rearward by spring 640, thereby allowing spring 612 to swing latch 610 out of the path of stud 614, so that the machine can be moved. released.



  The three tens keys 477 (fig. 29) select the even lines and, therefore, pressing these keys has no influence on the caliper 618 (fig. 42). When any of the keys 477 is used alone to select lines 10, 20, or 30, the pawl 621 kicks in and, in co-operation with the ratchet 492 of the even lines, this pawl prevents excessive table movement. as indicated above. The same is true when the 477 keys are used in conjunction with the 449 unit keys for even lines.

   When the tens keys 477 are used in conjunction with the odd keys 449, the file depression of the odd keys causes the caliper 618 to tilt in the senestorsum direction to ineffect the pawl 621. At the same time, the pawl 620 , which has become effective, engages with the odd-line ratchet 491 to prevent excessive displacement of table 335 in the manner indicated above.



   <I> Device </I> automatic <I> positioning </I> <I> of the </I> table.



  Referring to fig. 39, it will be seen that it is necessary for the lug 497 to engage with the notch 496 of the disc 407 in order to hold this disc and the bevel gear 406 stationary, so that the positioning of the shaft auxiliary 402 under the influence of the line finder keys is communicated to the main shaft 377 which in turn positions the table 335 (Figs. 19 and 46).

   It will also be remembered that the movement of the table 335 out of its normal position, caused by the search-row keys, forces the latch 519 to be placed below the stud 518 to prevent the lug 497 from holding the disc. 407 and gear 406 stationary, which would prevent the transmission to the shaft 377 of the positioning movements of the shaft 402.

    Subsequent action of the table set-up row finder keys 335 is, therefore, prevented, and control of the table proceeds to an automatic device, controlled by the transaction and totals keys, in a row. manner which will be described below.



  The automatic or consecutive advance of the table 335 is effected by the advancement ratchet 490 (fig. 43, 44, 45 and 46). Referring to fig. 45, it will be seen that the rocket is part of an assembly comprising the retaining ratchet 489, the gear 488 and the retaining ratchets 491 and 492, mounted in a fixed relationship with each other on the rotating hub 493. on shaft 402, a drive pawl 656 is engaged by a spring 658, with the teeth of the drive ratchet 490, the pawl pivoting on an elbow lever 657 loose on the shaft 402.

   The spring 658 drives the pawl 656 in the dextror- sum direction to bring it into normal engagement with the teeth of the ratchet 490. The elbow lever 657 is connected by a connecting rod 659 to a cam arm 660 loose on the rod 438 and driven. in the dextrorsum direction by a spring 661, so that a point of said arm is normally in contact with the periphery of an advancing cam of the table 662 fixed to the shaft 371.

         When rearward movement of connecting rod 659 is not inhibited, rotation of shaft 371 and cam 662 causes the point of arm 660 to be driven by spring 661 down a steep shoulder. 663 formed in a recess of the cam 662. These last movements occur according to the distribution indicated on line 13 of the graph (fig. 47). The dextrorsum movement of the arm 660 moves the connecting rod 659 rearward to swing the elbow lever 657 in the senestorsum direction, causing the feed pawl 656 to move rearward a distance d. 'a tooth of the ratchet 490.

   It should be noted that the retaining pawl 494 (fig. 43) cooperates with the teeth of the retaining ratchet 489, integral with the advancement ratchet 490, to prevent any rearward movement of the advancement ratchet 490 while the advancement pawl 656 is moved rearward in the manner described above.



  By continuing its rotation, the cam 662 forces a surface of the recess 663 to engage with the point of the arm 660 to cause said arm to tilt in the senestorsum direction against the tension of the spring 661. The connecting rod 659 is thus returned forward, so that the advancing pawl 656 advances the advancing ratchet 490 by one tooth in the dextrorsum direction. The gear 488 (fig. 43, 45 and 46) is fixed to the ratchet 49d and turns independently with this ratchet to drive the gear 487 and the shaft 486 in the senestorsum direction, thus forcing the gear 485, fixed to tree 486,

   driving the gear 403, the shaft 377 and, the drive gears 375 and 376 of the table (Fig. 19) in the dextrorsum direction, so that the table 335 is advanced on a line space.



  The rearward movement of connecting rod 659 (fig. 43) is controlled by various devices to ensure the proper alignment of table 335. For example, it is necessary that the totals control plate 73 be in the d position. 'addition before the connecting rod 659 can move rearward to actuate the drive pawl 656, which means that the drive pawl never operates when the totals control plate 73 is not in position. addition position.

   In the same way, the depression of certain keys of the transactions prevents the operation of the connecting rod 659 and the pawl 656, and a means is also provided to prevent the operation of the connecting rod 659 when the table 335 is in the process of being operated. move towards the selected line, under the influence of the search-line keys and associated devices.



  Referring to fig. 43, it will be seen that an angular extension of the connecting rod 659 carries a pin 664 cooperating with a notch 665 provided in a total control disc 666 idle on the shaft 315. The control disc 666 carries a gear 667 in mesh with a gear 668 attached to the shaft, 330. Referring to FIG. 6, it will be remembered that the shaft 330 is driven, by means of the gear train shown here, by the total control plate 73 in proportion to the total keys 74 to 78 inclusive, pressed (fig. 1).



  When the totals control plate 73 is in the add position, the control disc 666 is positioned, as shown in FIG. 43, so that the notch 665 of the disc is located vis-à-vis the stud 664. The result is that the connecting rod 659 has a free reciprocation, under the influence of the cam 662, to activate the rocket 490 for setting up the table.

   When the totals control board 73 leaves the add position, under the influence of one of the totals keys, during the totals and subtotals printing operations, the periphery of the disc 666 cooperates with the stud 664 to prevent rearward movement of connecting rod 659 and, therefore, to prevent operation of pawl 656 and ratchet 490. Connecting rod 659 (figs, 43 and 44) has a curved extension 669 which can engage with a loose ratchet 670 on a stud 671 fixed to a support 672 fixed to the frame of the machine.

   The pawl 670 is attached to a cam arm 673 driven in the senestorsum direction by a spring 674 to normally hold a roller 675 carried by said cam arm in contact with the periphery of a cam 676 attached to the shaft 315. A bracket 677 formed on the arm 673 is arranged to be engaged by a latch 678 attached to a hub 679 idle on the shaft 330. A cam lever 680, also attached to the hub 679, has a V-shaped surface disposed. to engage with a stud 681 attached to the cam 662.



  Referring to fig. 5, it will be seen that the shaft 315, which carries the cam 676, is connected by means of the gears shown here to the differential mechanism of the row of transactions <B> 270 </B> and that, therefore, said tree 315 is positioned in proportion to the transaction keys pressed. It will also be noted that the: cam 676 is divided into ten parts numbered from 0 to 9 inclusive, these spacings corresponding to the ten positions of the differential mechanism of the transactions.



  Let us assume, by way of example, that the latch 678 (fig. 44) is released from the square 677. It will be seen that the projecting parts of the cam 676, corresponding to positions 0, 1, 5 and 9 of the differential mechanism, engage with roller 675 to retain pawl 670 in the path of curved extension 669, to prevent any actuation movement of connecting rod 659.

   When the differential transaction mechanism is at zero (fig. 1 and 5) - for example, when no key in the row of transactions is pressed, or when the Statement = overdraft key 79 which takes position 1 is pressed, or when the Open key 86 in position 5 is dark, or when the Raise-scale key 84 which assumes position 9 is pressed a protruding part of the periphery of the cam 676 will be opposite the roller 675,

    holding the pawl 670 in the path of the curved extension 669 to prevent the operation of the automatic advance mechanism. When one of the keys Correct deposits 80, Space 85, Deposits 81, Checks 82, Unlock-deconvert 87 or Correct checks 83, in other words, the keys corresponding respectively to positions 2, 3, 4, 6, 7 and 8 of the cam 676, is depressed, this cam 676 is positioned by the differential transaction mechanism, so that the lower part of the periphery of said cam is vis-à-vis the roller 675,

   thus allowing the spring 674 to tilt the pawl 670 out of the path of the extension 669 to allow movement to the right of the connecting rod 659.



  Latch 678 and associated members are provided to hold pawl 670 in the path of extension 669 (fig. 43 and 44) during the first of a series of recording operations during which table 335 is advanced to the position chosen by pressing the search keys.



  It will be remembered that the first operation in a series of operations relating to the entry of checks consists in raising either a balance or an overdraft (Figs. 1, 2 and 3). During this operation the old balance is read and recorded in the balance totalizer, but normally this old balance is not printed on the statement sheet unless it is a transfer from this old scale to a new sheet.

       In this case, the Report balance key 88 is used in conjunction with the Balance report 84 or Report-overdraft keys 79 to print this balance at the place provided for this purpose, just above the first one. line of the statement sheet.

   After the operation to lift the old scale, the appropriate line finder keys are pressed to select the first available line of the sheet; the amount is dialed on the amount keys 71, and the transaction key corresponding to the item to be entered on the sheet is pressed.



  The Transaction key used in this latter operation is invariably one that selects a low portion of the periphery of cam 676, so that, without latch 678, pawl 670 would move out of the path of extension 669 to allow the connecting rod 659 to operate the automatic advancement device. But, since the latch 678 is effective during this second write operation, it prevents the release of the pawl 670, and the connecting rod 659 does not operate.

   Towards the end of the machine's operation, the stud 681, in cooperation with the cam-shaped projection <B> V </B> at the end of lever 680, swings said lever, and with it the hub <B> 679 </B> and the latch 678 in the senestrorsum direction against the tension of the spring 674 to disengage said latch from the bracket 677. This allows the spring 674 to immediately swing the arm 673 and the pawl 670 in. the senestrorsum direction out of the path of the extension 669 to bring them into contact with the lower part of the periphery of the cam 676.



  When the protruding part vis-à-vis the fifth position of the cam 676 (fig. 44) protrudes beyond the roller 675 - namely, during the 1-me depositing operation (where the 4-position of the cam is selected), after a check writing operation (where position 6 of the cam is chosen), or when the pawl 670 and the arm 673 are reset by this protruding part vis-à-vis the fifth position -, the latch 678 again engages the bracket 677 to prevent the feeding movement of the connecting rod during the next operation.

   However, this does not interfere with the operation of @la machine, since the items Checks and Deposits are always entered on the same line of the statement sheet when it is. necessary to move from one article to another. The same applies to positions 2 and 8 of cam 676, these positions corresponding respectively to Correction of deposits and Correction of checks. <B> He </B> has already been explained that a re-launch operation is invariably performed at the end of each set of enrollment operations.

   Pressing New Balance key 74 automatically selects positions 0 or 9 of cam 676, and since these positions are opposite a protruding part of the periphery of said cam, pawl 670 is returned. to its effective position, shown here, to prevent operation of connecting rod 659 and to return latch 678 and lever 680 to their effective positions, shown here.



  Referring to fig. 43, it will be seen that the cam 662 has at its periphery a slightly raised part 685, which communicates to the ratchet 490 a slight excess dental displacement, after which the pawl 656 is partially released from the tooth of said ratchet. This ensures that the ratchets 490 and 489 are advanced a sufficient distance to allow the retaining pawl 494 to engage properly with its corresponding tooth of the rock 489.



  A device which operates immediately after the excessive displacement of the rocks 489 and 490, indicated above, is provided to elastically drive said ratchets in a retrograde direction or in the senestorsum direction, when considering fig. 43, to ensure engagement of the teeth of rocks 489 and 490 with their respective pawls 494 and 656, so that table 335 is suitably set to the selected row position prior to operation of the imager. pressure.

   The device provided for putting the ratchets 489 and 490 back into engagement with their respective pawls 494 and 656 comprises a rocker 683 (fig. 23 and 24) connected, so as to be adjustable, to a spider 684 fixed to an extension of the latch. 'tree <B> 377 </B> which extends beyond the left frame 62. An operating arm 686 of the ratchet 683 is capable of rotating on a stud 687 aligned with the axis of the shaft 377 and mounted on a support 688 supported on a number of pins 689 fixed in the frame 62. The arm 686 carries a ratchet pawl 690 driven in the senestrorsum direction by a spring 691.

   The arm 686 also carries a stud 692 which is engaged with a notch 693 provided in the front end of a connecting rod 694, the rear end of which is articulated to one of the arms of a cam lever 695 idle on the shaft. rod 438. The cam lever 695 carries rollers 696 and 697, respectively cooperating with the peripheries of cam plates 698 and 699 mounted on the camshaft 371 of the print. A spring 700, maintained under tension between the stud 692 and a stud of the connecting rod 694, forms an elastic connection between the arm 686 and the connecting rod 694.

   When the mechanism is in the starting position shown here, an extension 701 of the pawl 690, in cooperation with a stud 702 fixed in the frame 62, retains said pawl out of engagement with the teeth of the ratchet 683.



  After advancing pawl 656 (fig. 43) has performed its forward and return movement, under the influence of cam 662, cam plates 698 and 699 (fig. 23) tilt lever 695 in the dextrorsal direction according to the distribution indicated in line 6 of the graph (fig. 47).

   This tilting of the lever 695 causes a movement to the right of the connecting rod 694 (fig. 23), lowering the arm 686 in the senestorsum direction to bring the pawl 690 into engagement with the teeth of the ratchet 683, and.

   'the subsequent movement of the cam lever 695 and of the connecting rod 694 forces the spring 700 to elastically drive the arm 686, the pawl 690 and the rocker 683 in the senestorsum direction to put the teeth of the ratchets 489 and 490 (Fig. 43) engaged with their respective pawls 494 and 656 to ensure that table 335 is set to exactly the row position that has been selected.



  Print drive shaft 371 (fig. 23 and 46) does. Lin turns in the dextrorsum direction during each machine operation, as has already been explained. This printing control shaft is connected to the main control shaft 70 by a gear train. During the add operations, the print drive shaft 371 rotates in synchronism with the main shaft 70. However, it will be remembered that during the total and sub print operations totals, the main shaft 70 turns twice.

   Considering the need for the printing mechanism control shaft 371 to make only one revolution during these operations, a clutch device is provided between the main shaft 70 and the connecting gears connecting this shaft to the shaft. print control tree 371. This clutch device is automatically disengaged at the beginning of the first cycle of the totals and sub-totals printing operations, so that the movement of the main shaft 70 is not communicated to the mechanism control shaft 371. printing during this first cycle.

   At the beginning of the second cycle of operations, said device is engaged to rolie the main control shaft to the control shaft of the printing mechanism, so that said printing control shaft makes one turn integrally. the main shaft during this second cycle of the totals and subtotals printing operation. Mechanism <I> of </I> unlocking <I> of the </I> table.



  Organs .represented in FIG. 38 are provided to release the feed and retainer pawls 656 and 494 of the table from their respective ratchets 490 and 489, so that the springs 386 and 392 (fig. 19) can return the table 335 to its position of. departure. This ratchet release device com takes a triggering cam 703 (fig. 38, 45 and 46) loose on the hub 493 and located between the two ratchets 489 and 490.

   Cam 703 carries trigger protrusions 704 and 705 co-operating with the teeth of pawls 656 and 494, respectively. Cam 703 has gear teeth which engage with like teeth of a segment 706 attached to a ring. shaft 707 journalled in frames 63 and 64.

   A crank 708 is also attached to the shaft 707; this crank is articulated at one of the ends of a rod 709 for controlling the release cam, this rod being provided with a slot in the form of <B> L </B> 710 which cooperates with a pin 711 provided on one of the arms of a lever with two arms 712 which is loose on the rod 438. Each of the arms of the lever 712 carries a roller 713 and 714 cooperating with the peripheries of cam plates 715 and 716 mounted on the camshaft 371 of the printing mechanism.



  The connecting rod 709 carries a square stud 717 arranged to be engaged by a latch 718 fixed to a shaft 719 journalled in the frames 63 and 64. An arm 720 is also fixed to the shaft 719, said arm being arranged to cooperate with a stud 721 protruding under the. table 335. A spring 722 (fig. 38) drives the latch 718 in the senestrorsum direction to normally hold a pin 724 carried by this latch in contact with the periphery of a cam 723 for driving the latch, fixed to the shaft. 315; it will be remembered that this tree is positioned by the differential mechanism of the rows of transaction keys in proportion to the keys of this dark row.

   Cam 723 is divided into ten parts corresponding to the ten positions of the differential of transactions, and the gaps are numbered from 0 to 9 inclusive. Cam 723 has a lower part which corresponds to positions 2 to 8 inclusive of the row of transactions, and said cam also has a protruding part corresponding to positions 0, 1 and 9 of said row of transaction keys.

   With reference. in fig. 1, it will be seen that positions 2 to 8 inclusive correspond to keys 80, 85, 81, 86, 82, 87 and 83, and that positions 0, 1 and 9 correspond to the automatic position and to the Statement-Overdraft keys. 79 and Survey 84.



  When the bottom of the cam 723 is opposite the stud 724, the spring 722 maintains the engagement surface of the latch 718 below the square stud 717, so that the horizontal branch of the slot forms of <B> L </B> 710 is in alignment with the stud <B> 711. </B> When the slot is in this position, the cam arm 712 has a reciprocating idle motion during the rotation of the cams 715 and 716, so that no movement is communicated to the connecting rod 709.

    When the protruding portion of the cam 723, corresponding to positions 0, 1 and 9, comes opposite the stud 724, the latch 718 is tilted in the outward direction to release its engagement surface from the square stud 717, which delivers the link 709 to the action of a spring 725 which drives said link down.

   It will be seen from the distribution shown in line 15 of the graph (fig. 47) that the initial forward movement of the cam lever 712, when the cams 715 and 716 begin to rotate, aligns the stud. <B> 711 </B> with the vertical arm of the L-shaped slot 710, so that the res exits 725 can immediately drive the link 709 down to engage the vertical arm of the slot with the stud 711.

   The dextrorally backward movement of cam lever 712 causes pin 711 to cooperate with the vertical portion of slot 710 to move link 709 rearward, causing crank 708 to swing counterclockwise. , the shaft 707 and the segment 706, so that the segment 706 switches the trigger cam 703 in the senestorsum direction.

   This movement in the senestorsum direction of the cam 703 engages the projections 704 and 705 with the teeth of the pawls 656 and 494 to swing said pawls out of engagement with their respective ratchets 490 and 489. The table 335 is immediately placed. delivered to action: springs 386 and 392 which return the table to the starting position.



  During the following operation, after the displacement in the sentrorsum direction of the vier 712 by the cams 715 and 716, a stud 726 (fig. 38) carried by the cam 715 engages with a flat surface 727 of the connecting rod 709 and raises this rod to put the horizontal part of the slot 710 vis-à-vis the pin 711.

   If, during this operation, the latch 718 is retained in the position indicated in fig. 38 by the protrusion of the cam 723, the link 709 is driven down by the tension of the spring 725 as the stud 726 descends from the flat surface 727 to bring the vertical part of the slot 710 back into engagement. stud 711 and, in this case, cam 703 releases pawls 656 and 494 out of engagement to return table 335 to the starting position.

   But if, during the second operation of the. machine, the cam 723 is positioned so that (the lower part is vis-à-vis the stud 724, the spring 722 acts immediately to return the latch 718 in the senestorsum direction to pass the engagement surface of said latch below the square stud 717 and in this case the horizontal branch of the slot 710 remains in alignment with the stud 711 as the stud 726 passes past the flat surface 727.

   In this case, the backward movement in the right direction of the lever 712 does not impart any movement to the link 709 and, therefore, the pawls 656 and 494 remain in engagement with their corresponding ratchets.

   If the latch 718 moves from its disengaged position, shown in fig. 38, to put itself in the engagement position under the influence of the cam 723 and the spring 722 when the rod 709-is in its bottom position, a flat formed on the beak of the latch 718 stops to the left side of stud 717, and latch engagement surface 718 engages with stud 717 when link 709 is returned upward through stud 726, as shown above.



  Note that the pin 726 always returns the link 709 upward immediately after the lever 712 has received its initial movement in the senestross direction. However, if the latch 718 is in its disengaged position, the link 709 moves downward as the stud 726 releases the flat surface 727 to bring the vertical leg of the slot 710 back into engagement with the stud 711.

   A device is also provided for ensuring the operation of the table delivery members when the first entry is made at line 39m0, so that table 335 is immediately returned to its starting position after this entry operation. This device comprises the pin 721, placed so that it can engage with the arm 720 to tilt it, with the shaft 719 and the latch 718, in the dextrorsum direction, when the table 335 is moved to the 39- line position by the feed pawl 656.

   The latch engagement surface 718 is removed from below the stud 717 to allow the vertical portion of the [. 710 engages with the stud 711, under the influence of the spring 725, at the end of the initial movement in the secestorsum direction of the arm 712.

   It should be noted that the cams 715 and 716 have a slightly raised profile, so that a stopping period occurs, so to speak, during which the lever 712 remains stationary at the limit of its travel in the sense senestrorsum and during which, also, the printing mechanism works to make the printing of the first article at the 39m0 line (see line 8-of the graph fig. 47).

   This printing operation finished, the cams 715 and 716 return the lever 712 in the dextrorsum direction and the rod 709 towards the rear, forcing the ears 704 and 705 to release the pawls 656 and 494 from their respective ratchets. 489 and 490 to allow springs 386 and 392 (fig. 19) to return table 335 to the starting position.



  In the event that it is necessary to print iul. Subsequent article to the 39-th line, it would be necessary to press the search-line keys 39 - that is to say the key 30 of the tens and the key 9 of the units - to put the table 335 back to the 39m0 position under the influence of these search-line keys.

   The mechanism shown in fig. 38 and described above operates whenever table 335 is moved to its 39m0 or last position, so that table 335 is returned to the starting position each time an item is carried to the journal sheet.

           Intermittent spacing <I> of the table </I> during <I> check entry operations. </I> Referring to fig. 2 and 3, it will be seen that the Debits part of the sheet combining an account statement and a bank ledger sheet comprises two columns for the entry of two articles one at a time. next to the other, entry after which the table is automatically spaced if there are still checks to be entered.

   It will also be seen that the Credits part of the sheet has only one column, so that only credits or deposits item can be entered in each row of the sheet. Therefore, when there is more than one credit item to be entered, it is necessary for the table to advance the sheet after entering each of these credit items. The automatic mechanism for controlling this automatic advance of the table 335 is controlled by the Checks 82, Deposits 81, Check Correction 83 and Deposit Correction 80 keys. This mechanism will be described in detail below.



  Referring to Figs. 32, 34, 35, 43 and 46, it will be seen that the stud 664 of the connecting rod 659 cooperates with the control disc 666 (fig. 43) which is controlled by the totals control plate 73 in the manner explained above. above. It will also be seen that the stud 664 also cooperates with a control disc 728 (Fig. 32) which controls the intermittent advance of the table 335 during check entry operations. The control disc 728 is integral with a gear 729 and a ratchet 730, said members being all idle on the shaft 315.

   The gear 729 is engaged with a gear 731 fixed to an intermittent feed shaft 732 journalled in the frames 63 and 64. The shaft 732 also carries a gear 733 (fig. 35) in engagement with an integral gear 734. a ratchet 735 loose on the shaft 315. An advancing pawl 763 (fig. 32, 34 and 46) engages with the teeth of the ratchet 730; this pawl pivots on a pin 764 of an arm 736 idle on shaft 315. A spring 737 drives the pawl 763 in the seneStrorsum direction in resilient engagement with the teeth of the ratchet 730. The pin 764 is engaged with a notch provided in one of the arms of a lever 738 idle on the shaft 330.

   The other arm of this lever has one in size engaged with a stud 739 of a cam lever 740 slack on the rod 438. The cam lever 740 carries a roller 741 which is resiliently in engagement with the periphery of the rod. a cam 742 fixed to the shaft 371, the roller being hand held in engagement with the periphery of the cam by a spring 743. The lever 738 carries a pin 744 (fig. 33) cooperating with a control disc 745 fixed to the 'tree 315; it will be remembered that said tree is positioned under the influence of the transaction keys. The selection disc 745 has notches 746 and 747 corresponding respectively to positions 6 and 8 of the differential mechanism of the transactions.

   It follows that the depression either of the Checks key 82, in the sixth position, or of the Check Correction key 83 in the eighth position, positions the notches 746 and 747 respectively of these keys vis-à-vis the stud 744 to allow the operation of the lever 738 and of the advancing pawl 763 by the cam 742. A retaining pawl 748, loose on the shaft 330, is driven in the senestorsum direction by a spring 749 to come into engagement with the teeth of the ratchet 730. The order disk has six notches of equal spacing. 750, and the feed ratchet 730 has twelve teeth.

   This ratchet is turned tooth. by tooth in the senestorsum direction by the cam 742 according to the distribution indicated in line 14 of the graph (fig. 47), so that a notch 750 and a solid part of the disc 728 between two notches are brought in turn -à -vis the stud 664. The ratchet 735 (fig. 35), which is connected with the ratchet 730, comprises a device for advancing it tooth by tooth, this device being similar in all respects to the positive di.ç- advancement of the ratchet 730 described above.

   This mechanism comprises an arm 751 loose on the shaft 315 and which carries a pin 752 forming the pivot of a pawl 753 driven in the senestorsum direction by a spring 754 to engage it with the teeth of the ratchet 735 The stud 752 engages a notch in one end of a lever 755 idle on the shaft 330. This lever 755 has a second in size which engages a stud 756 on one of the arms. a lever 757 mad on the rod 438.

   A spring 758 drives the lever 757 in the senestorsum direction, so that a roller 759 carried by said lever is normally engaged with the periphery of a cam 760 similar in all respects to the cam 742 (fig. 32). . This cam 760 operates the advancement mechanism, including the lever 755, in synchronism with the advancement mechanism for the ratchet 730. The lever 755 (fig. 36) carries a pin 761 placed so as to be able to cooperate with it. a control disc 762 fixed on the shaft 315, that is. positioned, as already explained, under the influence of the transaction keys.

   The control disk 762 has lower parts corresponding to positions 0, 1, 2, 3, 4 and 9 of the transaction differential; this disc also has protruding parts from its periphery corresponding to positions 5, 6, 7 and 8 of the differential transaction mechanism.



  Referring to fig. 35, it will be seen that the ratchet 735 has six teeth corresponding to the six notches 750 of the control disc 728. This ratchet and this disc are arranged relative to one another so that each forward movement on a distance of a tooth, communicated to the ratchet 735 by the mechanism indicated in fig. 35, brings a notch 750 vis-à-vis the stud 664 of the control rod of the advancement ratchet 659.

   Referring to fig. 1, it will be seen that the lower parts of the control disc 762 (FIG. 36) correspond to the transaction keys 79, 80, 85, 81 and 84; it will also be seen that when said disc 762 operates to advance the ratchet 735 by the lever 755, the control disc 745 is positioned so that its periphery blocks the stud 744, which prevents the forward movement of the lever. 738 to drive ratchet 730 (fig. 32).



  When the operation of the ratchet 735 is controlled by the disc 762 (Fig. 36), one of the notches 750 of the disc 728 (Fig. 32) is invariably brought opposite the stud 664. As a result, , when the disc 762 operates, the connecting rod 659 is not prevented in its reciprocating movement that it receives -the members shown in FIG. 43 and described above. This back and forth motion causes pawl 656 to advance ratchet 490 a distance of one tooth for each machine operation, to space table 335 and the statement sheet.

   It is evident that when the control disc 745 (fig. 33) controls the operation of the ratchet 730, the protruding parts and the notches 750 of the control disc 728 will be brought successively vis-à-vis the stud 664, so that the connecting rod 659 operates once in every two machine operations to advance the ratchet 490 by one tooth and, therefore, to advance the table 335 and the sheet.



  It will be recalled, with reference to FIG. 1, that during the registration of an account, the Balance statement key 84 is used first to read. the old scale. This key forces the differential transaction mechanism to position the control disks 745 and 762 so that the projecting portion of the disk 745 is opposite the pin 744 and a lower part, or notch, of the disk. 762 is vis-à-vis the pin 761. In this case, the ratchet 730, which has twelve teeth, does not work; but the six-tooth ratchet 735 operates to cause one of the notches 750 of the drive disc 728 to be brought opposite the stud 664.

   In this case, however, the connecting rod 659 is prevented by the cam 676 (fig. 44), this cam having reached its position 9, the position in which a protruding part of the cam is brought opposite the roller. 675 to retain pawl 670 in the path of re-curved extension 669, thereby preventing operator movement of connecting rod 659.

      The balance reading operation can be followed by a debit entry operation, for example checks. In this case, the amount of the first item of debits is dialed on the amount keys (fig. 1); the appropriate line finder key is pressed to select the first available line of the report sheet, after which the Checks key 82 is pressed to initiate machine operations. Check key 82 corresponds to position 6 of cam 676 and discs 745 and 762 (fig. 33,, 36 and 44) and, therefore, said members are brought to this position 6.

   In this position, a lower part of the cam 676 is located vis-à-vis the roller 675, the notch 746 of the disc 745 is vis-à-vis the pin 744 to release the advancement mechanism of the ratchet 730, and a protruding portion of the disc 762 is opposite the stud 761 to prevent the advancement mechanism of the ratchet 735. Usually, the lower portion of the cam 676 allows movement of the pawl 670 out of the shaft. path of extension 669. However, in this operation line finder keys were used to make the selection of the first print line; therefore, latch 678 prevents disengaging movement of said pawl 670 in the manner explained above.

   During. In previous balance raising operations, it will be recalled that the disc 728 was positioned such that one of the notches 750 was opposite the stud 664. Since the. cam 742 (fig. 32) operates after cam 662 (fig. 43) for controlling the feed ratchet 490, the connecting rod 659 would be free to operate during this check writing operation, and the table would be spaced if lo quet 678 was not (fig. 43) in position to prevent any movement of the table.



  Toward the end of the first check writing operation, cam 742 engages lever 738 so that ratchet 730 is advanced one tooth to bring a solid portion of disc 728 opposite stud 664. If there are still checks to be charged to the account, pressing the Checks key 82 at the start of this second entry operation forces cam 676 and discs 745 and 762 to remain in their positions of the first operation, which means that a protruding part of the disc 728 is opposite the stud 664.

   The movement of the connecting rod 659 is thus prevented, no movement is communicated to the feed ratchet 490 and the table remains in its pitch line position.



  It will be recalled, with reference to fig. 2 and 3, that the part of the sheet reserved for debits or checks is divided into two columns, so that two items can be entered on the same line. The two printing hammers which print these articles at alternating rates in the two columns are controlled by selection discs driven by the ratchets 730 and 735, in a manner entirely analogous to the disc 728. These hammers print the first article checks in the left column, the second in the right column, and so on. The control mechanism of these printing hammers will be explained below.



  After the printing movement, cam 742 moves lever 738 to cause pawl 763 to advance ratchet 730 to rotate disc 728, so that one key notch 750 is facing the 66-k stud. If there is another item to be entered in the checks during a subsequent operation, the connecting rod 659 is free to move the pawl 656 to advance the ratchet 490 by one tooth to bring the next line of the sheet to the position d. 'printing, so that the third item is entered in the left column of the debits section (fig. 2)

   immediately below the first article. This intermittent advance of the sheet is repeated as long as you want using the Checks key 82.



  Referring to the drawing, it will be seen that the Check Correction key 83 operates in a completely analogous manner to the Checks key 82 to position the cam 676, so that a lower part of this cam is opposite the roller 675, to position the disc 745, so that the notch 747 of this disc is opposite the stud 744, and finally to position the disc 762, so that a protruding part of this disc is facing to stud 761. As a result, the intermittent feed mechanism operates exactly as explained with respect to Checks key 82.



  Let's say, for example, that updating an account requires recording a series of deposits other than checks. Pressing the Deposits key 81 at the start of a deposit operation moves the cam 676 (Fig. 44) from the sixth position, through the fifth position, to the fourth position.

   When the. cam is in the fifth position, the projecting part of the cam in this fifth position, in cooperation with the roller 675, brings the pawl 670 into the path of the extension 669; latch 678 re-engages with bracket 677 and retains pawl 670 in the path of said extension 669 when the cam moves to the fourth position, which is a down position.



  Positioning the differential transaction mechanism under the influence of the Deposits key also moves disks 745 and <B> 762, </B> so that the fourth positions of these discs are opposite key studs 744 and 1t 761, to disengage the ratchet control mechanism 730 and to engage the ratchet control mechanism 735. Considering that the articles of the deposits are printed on a part of the sheet quite different from that of the checks, it is advantageous to enter the first of these articles in the. same line as last of check items.

   During this first deposit registration operation, the latch 678 (fig. 44) functions to prevent the advancement of the table, and this also when a notch 750 or a solid part of the disc 728 is opposite. stud screw 664. During this first deposit registration operation, cam 760 (fig. 35) operates pawl 753 to advance ratchet 735.

   It makes no difference whether, in the next operation, one of the notches 750 or one of the solid parts of the disc 728 was opposite the stud 664;

   the movement of the ratchet 735 brings one of the notches 750 vis-à-vis the stud 664 during the latter part of the first registration-of the deposits operation. Towards the end of this first deposition registration operation, the device shown in FIG. 43 and explained above releases the lo quet 678, so that the -patch 670 can deviate from the path of the extension 669.



  If it is necessary to carry a second item of the deposits to the account, pressing the Deposits key 81 at the start of this second operation causes the cam 676 and the discs 745 and 762 to remain in the positions they were put in during the first operation. Towards the end of this second operation, the mechanism shown in FIG. 35 advances disc 728 to bring the next notch on the disc opposite stud 664.

   However, the mechanism shown in FIG. 43 operates prior to displacement of disk 728, as. that we have just indicated. Since a notch 750 is opposite the stud 664, and the pawl 670 (fig. 44) no longer prevents the connecting rod 659, this connecting rod functions to move the table 335 and, with it, the sheet, one line before the operation of the printing mechanism. As a result, the next item in the deposits prints immediately below the first item, and the table and sheet move as shown for each of the subsequent items.



  Referring to the drawing, it will be seen that the deposit correction key 80 (fig. 1) functions in a manner analogous to the deposits key 81 to advance the sheet after each entry of this kind. It would be necessary to explain that bank charges and other debit items are charged to the Debit portion of the sheet, exactly as noted above with respect to checks, using the Checks 82 key.

   With regard to credits other than deposits, the entry of these items is done in exactly the same way as the entry of deposits using the symbol keys 90 (fig. 1) to indicate the different items. articles.



  After all debits and credits have been entered, the next operation during an account update is a new balance operation. One will recall that pressing the New Balance key 74 positions the differential transaction key mechanism in the ninth position. If the balances totalizer is. When uncovered, the New Balance key is locked and can only be unlocked by first pressing the Overdraft key 86, which resets the differential mechanism of the transaction keys to zero.

   During so-called new balance operations, cam 676 (fig. 44) is positioned at 9 or 0; these two positions cause a projection of the cam vis-à-vis the roller 675 to bring the pawl 670 in the path of the extension 669, preventing. thus the action of the connecting rod 659 and of the mechanism for advancing the table. The printing of the new balance is made, therefore, on the same line as the last of the articles of the deposits, but in a different column; this balance is also printed at the same time on the part of the sheet which represents a ledger sheet.



  If the operations necessary to bring a particular current account into use include two entries of debits or checks, one entry of credits or deposits and a new balance, all these entries shall be made on the same line in the manner indicated. on line 37 of sheet 343 (fig. 2).

   Both debits or checks are written exactly as above. The movement of the cam 676 (fig. 44) from the Checks position;> to the Deposits position before the registration of the deposit forces the projecting part vis-à-vis 5 of said cam to. put back the ratchet <B> 670. </B> During this reset movement, latch 678 maintains this pawl in an effective position when the protruding portion of cam 676 leaves roller 675, so that the item of credits or deposits is entered. on the same line as the two debits items.



  Depression of the New Ba lance key at the start of the next operation rotates cam 676 to the ninth position, where a protruding portion of the periphery of this cam returns pawl 670 to the path of extension 669 to counter square the forward movement of the connecting rod 659, so that the new scale is printed at, the same line as the two debits and the credit.



  It is necessary to underline that the Rolevé-uncovered key 79 (fig. 1) turns the cam 676 to position 1; in this position, the pawl 670 prevents the forward movement of the connecting rod 659. The Raise-balance key 84 causes the displacement of the cam 676 to position 9. In this position too, the pawl 670 prevents the advancement of the table and the sheet.



   <I> Device </I> alignment <I> disks </I> <I> of </I> command <I> and the associated mechanism </I> to these disks.



  A device shown in FIG. 37, and which will be discussed below, is intended to hold the shafts 315, 330 and 732 and the control disks positioned by these shafts in alignment and to guarantee them against any displacement during the operations of the machine. This device includes three identical discs, or star wheels <B> 765, </B> 766 and 767, each of which has twelve V-notches corresponding to the twelve teeth of the ratchet 730 and, of course, every second tooth of these discs corresponds to the teeth of the ratchet 735. The disc 765 is fixed on the shaft 315 controlled by the transaction keys. Disk 766 is crazy on shaft 315; a gear 768, attached to the disc 766, is engaged with a gear 769 attached to the shaft 330 controlled by the totals control plate 73.

   Disc 767 is also insane on shaft 315; a gear 770, integral with the said 767, is engaged with a gear <B> 771 </B> fixed to the shaft 732 controlled by the ratchet system shown in fig. 32 and 35. The alignment V-notches in the discs 765, 766 and 767 are arranged to be engaged by an alignment V-bar 772 attached to a curved portion of one of the arms of a lever. 773 idle on a fixed pin 774 and driven in the outward direction by a spring 775, so that a roller 776 carried by said lever comes into contact with the periphery of a cam 777.

   When the shafts 315, 330 and 732 (fig. 37) and the disks associated with these shafts have been put in position, the cam 777 allows the spring 775 to tilt the lever 773 according to the distribution indicated in line 5 of the graph (Fig. 47), so that the alignment bar 772 engages the teeth of the discs 765, 766 and 767 to hold the shafts and control discs associated with these shafts against displacement.

   After the printing movement, the cam 777 releases the alignment bar 772 from the discs 765, 766 and 767. 'Mechanism <I> of </I> counting <I> of </I> checks. An automatic and manual device is provided for counting checks. This arrangement consists of a row of unit keys 72 and a row of tens keys 52. These rows, located at the far left of the keyboard (Fig. 1), are similar in many respects to the rows of upright keys. 71, although there is no connection between the check counter keys and the amount keys.

   This automatic check counter is controlled by the Checks key 82. Depression of this key controls the zero stop pawl for the check counter unit row. This zero stop pawl carries, apart from the usual zero stop, a stop located at position 1 of the row of units 72. Depression of the Checks key 82 brings this second stop to the path of. differential spider for the row of check counter units, to add 1 to the check totalizing wheels.



  The Check Correction key .83 is used to withdraw or cancel a check entered in error. This key also controls the rows 72 and 52 of the automatic check counter to effect the under traction of 1 to the wheels of the check counter in compensation for the cancellation of a check. This subtraction of 1 from the wheels of the check counter is carried out by adding the complementary number 99 to these wheels.

   Pressing the Check Correct key releases the zero stop pawls of the ones and tens so that the differential mechanism of the check counter key rows is free to move to the ninth position for perform this subtraction.



  It is standard practice to put all checks of some kind or designation in a bundle; the amount of the checks is entered on the amount keys and recorded as a single item using the Checks key 82. In this case, the keys 72 and 52 of the two rows of the check counter are used to compose the total number of checks in a bundle. Depression of these keys disengages the automatic mechanism of the check counter and records the total number of checks in a bundle on the wheels of the check counter. This check counter mechanism will be explained more fully below.



  The rows of check counter keys 72 and 52 (fig. 1) are similar in construction to the rows of upright keys 71 (fig. 4). Each row comprises a differential mechanism with a cross 778 (fig. 9) for the keys of the units 72 and a cross 779 (fig. 11) for the tens keys 52. These crosses are analogous, in construction and in function, to brace <B> 97, </B> for the row of upright keys, shown in fig. 4.

   The spider 778 for the row of units has a pin 780 with a flat cooperating with a zero stop surface 781 and with a surface 782 corresponding to position 1 of the differential mechanism of the units. These surfaces form part of a zero stop pawl 783 mad on a shaft 784 journalled in the frame of the machine. A torsion spring 785 is wound around the shaft 784; the opposite ends of this spring engage respectively with. a stud 786 of the stopper 783 and with a bushing mounted on the rod 101.

   This spring drives the detent pawls in the forward direction so that a shank 787 'of the pawls is normally in contact with the net cushion on the rod 101.



  The differential spider 779 for the tens keys 52 carries a pin 788 with a flat cooperating with a zero stop surface 789 of a zero stop pawl 790 mad on the shaft 784. This pawl. is driven in the dextrorsum direction by a torsion spring 791 wound around the shaft 784. The opposite ends of this spring engage respectively with a stud 792 of the pawl 790 and with the bearing on the rod 101, of dewlap that a tail 793 formed on said pawl 790 is in contact with the bearing on the rod 101. The stud 786 carried by the zero stop pawl 783 of the row of keys of the units cooperates with a lever 795 to which it is superimposed.

   This lever 795 is fixed in a constant ratio with a finger 796 (fig. 9 <B>) </B> by a hub 797 loose on the rod 101: The finger 796 (fig. 9) cooperates with a stud 798 provided in an upward extension of an arm 799 loose on a stud 800 mounted in the frame of the rows of keys. The arm 799 has an extension finger 801 cooperating with a rod 802 supported by a number of cranks 803 attached to the disconnection shaft 204 of the zero stop pawl (see also FIG. 4).



  Devices similar to those just described are also provided for the tens keys 52 (FIG. 11) of the check counter. The stud 792 of the zero stop pawl 790 is superimposed on an arm 804 with which said stud cooperates. The 804 arm is connected by an 805 hub, loose on the rod <B> 101, </B> to iln finger 806 which cooperates with a stud 807 provided in the upper extension of an arm 808 loose on a stud 809 mounted in the framework of the tens keys. An extension finger 810 of the arm 808 cooperates with the rod 802 in exactly the same way as the finger 801 of the arm 799 (Fig. 9).

   The studs 798 and 807 (Figs. 9 and 11) of the arms 799 and 808 also cooperate with similar cam surfaces formed on corresponding pivoting levers 811 and 812 respectively. on studs 813 and 814, these studs being mounted respectively. in the frames of the units and tens keys. A lever control bar 815 is freely connected to the lever 811; the upper end of this bar is loosely connected to the key frame, so that the bar can be moved. This bar 815 has a number of cam surfaces 817 which cooperate with studs 818 in each of the keys of the units 72.



  Depression of one of the keys of the units 72 causes the stud 818, in cooperation with the cam surface 817, to move the bar 815 downward to tilt the lever 811 in the forward direction. This movement in the dextrorsum direction of the lever 811 forces the cam surface of this lever, in cooperation with the stud 798, to tilt the finger 796, the hub 797 and the lever 795 in the senestrorsum direction. This movement in the senestorsum direction of lever 795 is communicated by stud 786 to zero stop pawl 783.

   As a result, said pawl is tilted to the second position, represented by a dashed line; in this position, surface 0 781, as well as surface 1. 782, are spaced from the path of the stud 780, so that the spider 778 and its associated differential mechanism are positioned under the influence of the key 72 pressed.



  The lever 812 for the tens row of the check counter 52 is loosely connected to the lower end of a control bar 816, similar in all respects to the control bar 815; this bar has a number of cam surfaces 819 which cooperate with studs 820 in each of the tens keys 52 of the check counter.

   Depression of any one of the keys 52 causes the lever 812 to tilt, causing the zero stop pawl 790 to tilt for the row of tens; this stop pawl is tilted in the senestrorsum direction against the tension of the spring 791 towards the position shown in phantom in fig. 11. The zero stop surface 789 of this pawl is thus spaced from the path of the stud 788, so that the crossbar 779 and its associated differential mechanism are positioned under the influence of the tens key 52 of the check counter. that has been pressed.



  In the printing operations of totals and subtotals, the shaft 204 (fig. 9) is tilted in the dextrorsum direction. This movement is communicated to the cranks 803 and to the rod 802, forcing said rod to engage with the fingers 801 and 810 of the arms 799 and 808 (fig. 9 and 11),

   so as to make the said arms swing in the senestrorsum direction. This movement in the senestorsum direction of the arms 799 and 808 and transmitted by the studs 7 98 and 807 to tilt the fingers 796 and 806 and the levers 795 and 804 also in the senestorsum direction jointly with the arms 799 and 808.

   The senestrorsal movement of the levers 795 and 804 is transmitted by the studs 786 and 792 to the respective zero stop pawls 783 and 790 to switch these pawls to the non-operating position explained below. above. The spiders 778 and 779 are therefore free to be placed in position by the check counter wheels for the purpose of recording the total number of checks, as described below.



  * Lever 795 (fig. 9) for the keys of the check key counter units has a slot in <B> L </B> 821; a stud 822 that goes to. through this slot is engaged with a projection 823 of the zero stop pawl 783. The stud 822 (fig. 9 and 10) is fixed in a crank 824 fixed to the shaft 784. The lever 804 (fig. 10 and 11) has an L-slot 825; a stud 826 which passes through this slot cooperates with a projection 827 of the zero stop pawl 790 for the tens keys 52.

   This stud 826 is fixed in a crank 828 fixed to the shaft 784. It will be remembered that the shaft 784 extends over the entire length of the machine. A crank 829 is attached to this shaft near its right end; this crank is connected by a connecting rod 830 to a control segment 831 for the transaction keys; this segment is supported and rotates on a pad 832 aligned with the axis of the pad 99 (fia. 4) for the row of uprights shown.

   A spring 833 drives the segment 831 in the dextrorsal direction to maintain a cam surface 834 of this segment (fia. 8 and 1.0) in contact with a stud 835 provided in one of the arms of a caliper 836 loose on a rod 837 pressed on the support plates of the rows of keys. The caliper 836 is. connected by a connecting rod 838 with a crank 839 fixed to the key locking shaft 69.



  When the machine is triggered in the manner indicated in connection with the fia. 4, the movement in the dextrorsum direction of the key locking shaft 69 is communicated by the connecting rod 838 to the yoke 836 (fia. 8) which swings in the senestrorsum direction to move the pin 835 away from the re-part. lifting of the. cam surface 834.

   This allows the spring 833 to drive the segment 831 elastically in the dextrorsum direction. Each of the transaction keys 79, 80, 85, 81 and 87 has a pin (fia. 1 and 8);

   when any one of these keys is pressed, the pin which it carries engages in a corresponding notch 841 made in the periphery of segment 831, so as to prevent the drive in the dextrorsal direction of said segment by the spring 833 when the key locking ar ber 69 is tilted in the dextrorsum direction by the triggering operation of the machine.



  Transaction key 84 has a stud that moves in the path of a shoulder 842 formed at the right end. from the periphery of segment 831 ,. to prevent forward movement of segment 831. Therefore, when any ale of the named keys is pressed, segment 831 does not operate. The Checks key 82 has a stud arranged to cooperate with a checkmark 843 in the periphery of the segment 831.

    This notch 843 is appreciably larger than the notches 841, so that there is between the left side of the notch 843 and the stud of the Checks key 82 a sufficient offset to allow the partial displacement of the segment 831 by the spring. 833 when the key lock shaft 69 is tilted at the start of machine operation. This partial displacement in the dextrorsum direction of the segment. 831 is transmitted by the connecting rod 830 to tilt in the senestorsum direction the crank 829, the shaft 784 (fia. 8, 9 and 10), the crank 824, and the pin 822. All these members tilt.

    in the senestrorsum direction a sufficient distance to allow the pin 822, in cooperation with the projection 823 of the stop pawl at zero 783, to swing this pawl in the senestrorsum direction against the action of the spring 785, so that the stop surface 781 of this pawl is moved away from the path of the stud 780, while the stop surface 1782 is brought into the path of said stud.

   It follows that when the. Checks key is pressed during the operation of the machine, the differential mechanism of the keys of the check counter 72, with the spider 778, will be brought to position 1 under the influence of the surface 782, instead of be stopped at zero; in this way, 1 is automatically added to the check counter wheels.



  There is a transfer mechanism from the unit wheels to the tens wheels of the check counter; this device transfers the tens digit when the units wheel crosses the 0 position. The check counter wheels are mounted on line N 1 of totalizers, or line of balance totalizers (fia. 4). The check counter is an addition / subtraction totalizer capable of being moved sideways, so as to bring the plus or minus side into engagement with the post drivers. It is therefore necessary to provide two wheels in each series of rows of the check counter.

   These two wheels are not meshed so as to rotate in opposite directions, like the wheels of the balance totalizer; on the contrary, they are fixed in a constant relation to each other and in effect they function as a single addition wheel. It is thus possible to add checks to the wheels of the check counter when the scale counter is in the subtraction position under the influence of the Checks key 82; it is also possible, in this way, to read the total or the subtotal of the check counter wheels at the same time as the total or the subtotal is read on the plus or minus side of the counter. scales.



  Movement of shaft 784 a partial distance, caused by depressing the Checks key 82 as explained above, also drives crank 828 (Figs. 10 and 11) and pin 826 for the keys. tens of the check counter 52; this crank and this pin move integrally with the shaft 784.

   It will be seen, however, by referring to FIG. 11, that there is sufficient clearance between this stud 826 and the extension 827 of the zero stop pawl 790 of the tens keys; thus, no movement is communicated to this stop pawl at zero 790; stop surface 789 remains in the path of stud 788 to position the differential mechanism of the tens row of the check counter to zero.



  The Check Correction key 83 is used in the manner explained above for the correction of a check or debit item entered in error during a previous transaction; since this check, entered in error and which must be canceled, was counted automatically by the mechanism of the check counter, it is therefore necessary to subtract 1 from the wheels of the check counter during a check operation. correction of checks. Referring to fig. 10, we'll see. that the Check Correction key 83 does not have a stud like the other transaction keys, and no notch is provided for this key in the periphery of segment 831.

   Therefore, pressing the Check Correction key allows full forward movement of segment 831 when the machine is tripped. This complete movement is communicated to the shaft 784, the crank 824 and the pin 822 (fig. 9, 10 and 11) to switch the stop pawl to zero 783 of the keys of the units 72 of the check counter a sufficient distance to bring the surfaces 781 and 782 out of the path of the stud 780.

   The movement of the shaft 784, the crank 828 and the stud 826 forces said stud 826, in cooperation with the. projection 827, in moving the zero stop pawl 790 over the full distance of its path in the senes- trorsum direction, to move the zero stop surface 789 of this pawl away from the path of the stud 788. This releases the differential mechanism of the row of units and tens of the check counter; this mechanism moves to the ninth position to add the complementary number 99 to the check counter wheels, which is the same as subtracting 1.



  It is sometimes necessary to use the Checks key 82 (fig. 1) in conjunction with the Amount keys 71 for entering items other than checks; in this case, it becomes necessary to disengage the automatic mechanism of the check counter.

   With regard to current accounts, the most common item of this kind represents bank charges; when this article is registered, the automatic mechanism of the check counter is disengaged by the depressing of the key SC of the symbol keys 90, this symbol always indicating an article of bank charges. It is sometimes necessary to disengage the check counter in connection with the entry of checks or other debits. Pressing the key <B> NC </B> 90 disengages the automatic check counter so that these items are not counted.



  A crank 844 is attached to the shaft 784 (Fig. 10); this crank is connected by a connecting rod 845 to a control segment 846 of the symbol keys 90; this segment, adjacent to the control segment 831, pivots on the bush 832. A spring 847 drives the segment 846 in the dextrorsum direction, so that a cam surface 848 of an extension of this segment engages the stud 835 exactly as shown for segment 831.

   The symbol key SC 90 (fig. 1 and 10), indicating Ban c Fees, and the NC key, meaning Not counted, each carry a stud arranged to cooperate with corresponding projections 849 and 850 formed at the periphery of the segment. 846.



  The way in which the segment 846 is connected to the shaft 784 causes the movement - of this segment integrally with <B> - </B> segment 831 when the key lock shaft 69 (fig. 8) is driven in the dextrorsum direction at the start of machine operation. Pressing the SC key or also. the NC key of the symbol keys 90 drives the pin carried by the pressed key on the path of the corresponding projection 849 or 850.

   The dextrorsal movement of segments 846 and 831 is inhibited, preventing the operation of the automatic check counter mechanism even when the Checks key 82 is pressed. The depression of one or the other of these keys also causes the printing of a symbol next to the corresponding amount on the sheet.



  Since the Checks key 82 (fig. 1) is used in conjunction with the Sub-total transactions 76 and Total transactions 77 keys for reading or resetting the totalizer of checks on line N 2; of the totalizers, it It is necessary to provide a means controlled by the keys 76 and 77 and by the other totals keys to prevent the operation of the automatic mechanism of the check counter during these read and reset operations.



  Referring to Figs. 1, 7 and 10, a totaling row control bar 857 is mounted on two studs 858 in the frame of the totals keys. These studs are engaged in grooves of the control bar, so that the bar is capable of movement. circular. The bar 857 has a number of cam projections 851 cooperating respectively with studs of each of the control keys 74 to 78 inclusive and of the carry-over key 88.

   The lower end of bar 857 has a notch which engages a stud 852 of a latch 853 loose on the rod 101; a slit in <B> L </B> 854 is formed in an extension. to the right of this latch; a pin 855 of a crank 856 fixed to the shaft 784 passes through this slot in <B> L. </B>



  Depression of any one of the control keys 74 to 78 inclusive, or of the Balance carry key 88, pledges the stud carried by the key with the corresponding projection 851, so as to move the bar downwards. control 857, tilting the latch 853 in the senestrorsum direction. The vertical part of the slit in <B> L </B> 854 engages with stud 855 to hold crank 856 and shaft 784 against movement, preventing operation of automatic check counter mechanism.

   When none of the totals control keys are pressed, the horizontal part of L-slot 854 is opposite stud 855, as shown in fig. 7, to allow free movement of shaft 784.



  Depression of any one of the keys of the check counter units 72 (fig. 9) causes the pin 818 of this key, in cooperation with the cam surface 817 of the control bar 815, to tilt the lever 811 in the dextror- sum direction, which forces the cam surface of this screw, in cooperation with the stud 798 and the finger 796,

   to tilt lever 795 in the senestrorsum direction. This latter movement brings the vertical portion of the L-slot 821 of said lever into engagement with the stud 822 to lock the shaft 784 and to disengage the automatic check counter when a key of the units 72 of the check counter is pressed. A similar device shown in fig. 11 and described above is provided for the tens keys of the check counter 52.

   The depression of any one of these keys causes a tilting in the senestorsum direction of the arm 804 for this key, so that the vertical part of the slot in <B> L </B> 825 is brought into engagement with pin 826 to lock shaft 784, thereby rendering the automatic check counter mechanism inoperative when any of the tens keys are pressed, even if the key Check 82 (fig. 1) is used to start the machine.



  The locking mechanism just described is essential to prevent operation of shaft 784 when check counter keys 72 and 52 are pressed. Let us say, for example, that it is necessary to dial the number 20 on the keys of the check counter. In this case, the 2 key in the tens row is pressed, and no key is pressed in the ones row.

   Since the Checks key 82 is used to initiate such an operation, the surface 1782 of the zero stop pawl 783 of the row of units would be brought into the path of the stud 780 to perform the automatic addition from 1 to the row of check counter wheel units; but this addition is prevented by the locking mechanism shown in fig. 11. This mechanism locks the shaft 784 so that the 781 surface of the zero stop pawl 783 remains in the path of the pin 780 to set the differential of the check counter unit row to zero.



  In the to rate and subtotal printing operations, the operation of the decoupling shaft 204 and the rod 802 causes the slots 821 and 825 to engage with the studs 822 and 826.

   This triggering is fortuitous and relates to the construction of the machine; Obviously, a locking of this kind is not of primary importance, since the depressing of any of the control keys for the totals, 74 to 78 inclusive, or of the Balance to be transferred key 88 will have already locked the shaft 784, and this before the shaft 204 has received a movement in the dextr orsum direction sufficient to lock the shaft 784. <I> Control mechanism </I> alternative <I> from the printer of </I> checks.



  Referring to Figs. 2 and 3, it will be remembered that passive items and checks are printed in two columns in the debits portion of the combined sheet. It is necessary for this to arrange the two printing hammers so that one operates during the first printing operation and the other during the following printing operation and so on. Fig. 22 shows the reciprocating hammer drive mechanism that prints in the left column of the sheet feed portion.

   Since this mechanism is largely identical to the printing mechanism for the right column, a description of the mechanism shown in fig. 22 is sufficient for understanding the mechanism.



  The intermittent advance control shaft 732 is driven by the ratchets shown in FIGS. 32, 34 and 35 as indicated above. A gear <B> 859 </B> (fig. 22), attached to this shaft 732, is engaged with another gear 860 attached to an intermittent control disc <B> 861 </B> crazy on). 'Shaft 315. The say 861 has six notches 862 spaced evenly apart from each other in exactly the same way as notches 750 in drive disc 728 (Fig. 32).

   The totals drive shaft 330, which is controlled by the rate control keys as explained above, carries a gear 863 in mesh with a similar gear (not shown) attached to a drive disc. Totals 864 crazy on shaft 315. Disk 864 has a notch 865 corresponding to the addition position of the totals control plate 73. This disk 864 is similar in all respects to disk 666 (Fig. 43). that notch 865 corresponds to the addition position of the totals control board 73.

   Attached to shaft 315 - this shaft being put in position, we will remember, by the keys of the transactions - is a control disc 866 which has two notches (not shown) corresponding respectively to positions 6 and 8 of the differential transactions. It will be remembered that these positions 6 and 8 are respectively the Checks and Checks Correction positions.



  The three control discs 861, 864 and 866 (Fig. 22) cooperate with three of four upper feeler fingers 867 and, furthermore, the totals control disc 864 is in cooperation with a lower feeler finger 868.

   These feeler fingers are assembled in a unit and pivot on a stud 869 carried by a crank. <B> 870 </B> connected by an idle hub on shaft 512 to an arm 871. A spring 872 drives arm 871 into engagement with a stud 873 of a drive arm 874 idle on shaft 512 and connected to a drive arm 875 controlled by a cam as shown in line 7 (fig. 47). A connecting rod 876 connects the arm 871 to a connecting rod 877; a stud 878 in the front end of this link 877 may engage a notch 879 provided in a hammer control lever 880 slack on the rod 498.

    The lever 880 has at its upper end a pin 881 slack in one end of a hinged lever 882. The upper end of this lever is hinged with a hammer for printing checks 883 slack on the handle. shaft 528. Print hammer 883 carries print block 884. Operation of the hammer moves block 884 upwardly through one of the openings 340 of table 335 to feed sheet 343 and ink ribbon 885 superimposed on the sheet in contact with the character-carrying wheels of the uprights 153 corresponding to the first column, the one on the left, of the Debits part of the sheet.

   An adjustment by means of an eccentric 886 is provided between the lever 880 and the articulated lever 882 to adjust the position of the printing unit 884 with respect to the character wheels of the uprights 153, to ensure a low pressure. suitable. The other end of the drive rod 877 is articulated to an arm 887 connected by a hub 888, loose on the rod 438, to an arm 889.

   The arms 887 and 889 respectively carry rollers 890 and 891 which cooperate with the peripheries of cam plates 892 and 893 fixed to the printing shaft 371, these cams. operating according to the distribution shown in line 8 of the graph (Fig. 47).



  The movement in the senestorsum direction of the arms 875 and 874, under the influence of their cams and of the spring 872, carries the arm 871 together with these arms to force the feeler fingers 867 and 868 to feel the control discs 861 , 864 and 866.

   Since the periphery of the drive disk 864 is always opposite the feeler finger 868, this finger never engages with a notch, so that it always functions to prevent the operation of the printing hammers. unless three notches of the discs 861, 864 and 866 are opposite the three corresponding fingers 867, which allows the arm 871 to receive sufficient movement to bring the stud 878 into engagement with the notch 879, after whereby the operation of cams 892 and 893 forces the hammer mechanism to operate.



  The fourth feeler finger 867 cooperates with a curved surface of the segment 531 (Fig. 22). It will be remembered that this segment is controlled by the feeler mechanism of the sheet shown in FIG. 40 and described above. Therefore, in the absence of a sheet on the table 335, the curved surface of the segment 531 moves in front of the corresponding feeler finger 867 to prevent the engagement of the stud 878 with the notch 879, so that the printing hammer does not work.

   As the notches of the transaction control disk 866 correspond to the Checks and Check Correction keys, it is necessary to press one or the other of these keys to bring the corresponding notch opposite the corresponding probe finger. responder 867 before stud 878 can engage with notch 879. It is also necessary for the totals control plate 73 to be in the add position to bring the notch of the totals control disc 864 screw -to the corresponding finger 867 before the stud 878 can engage with the notch 879.



  Since inward movement of finger 868 is always prevented by the totals control disc 864, it is necessary that all four fingers 867 be free before stud 878 can engage notch 879 to make operate hammer 883.

   The control disc 861 (fig. 22) is meshed with the intermittent control shaft, in such a way that with each operation carried out in order to raise a balance or an overdraft, the ratchet 735 (fig. 35) , which is effective during these operations, brings one of the notches 862 of the disc 861 vis-à.-vis the corresponding feeler finger 867. - During the next check writing operation, this notch remains in front of the corresponding feeler finger for a long enough time to allow the operation of the arm 871. Since the feeler fingers 867 are all free to move. move inwards, the stud 878 will engage with the notch 879.

   Consequently, the impression hammer 883 will be pushed by the cams 892 and 893, so as to effect the printing of the amount of the first flow or check that in the first column, the one on the left, of the flow section of the flow. leaf.



  After printing, the ratchet 730 (fig. 32), made effective by depressing the Checks key 82, is advanced by one tooth to move the notch 862 away from the path of the corresponding feeler finger 867 and to bring the solid part of the periphery of the control disc 861 on the path of this finger pale fear. Therefore, the hammer mechanism shown in fig. 22-is rendered inoperative during the next check writing operation, because the inward movement of the upper feeler fingers is prevented, so that the pin 878 does not engage in the notch 879 .

   Note that the stud 878 engages a cam surface 894 of the lever 880 to tilt this lever in the dextrorsal direction when the link 877 is moved upward. This brings a surface of the anterior edge of this lever into engagement with tie rod 66 to rock hammer 883 into the down position, shown here, which brings print block 884 below. table 335.



  It becomes evident, by comparing lines 7, 8 and 14 of the graph (fig. 47), that the cams, according to line 7, control the forward movement of arm 871 to engage stud 878 with the notch. 879; that the cams, according to line 8, control the movement of the rod 877 to actuate the May: printing plate 883; while line 14 indicates the timing of cam 742 (fig. 32) for driving ratchet 730.

   It emerges from this comparison that the cams: (lines 7 and 8) which control the palpation action of the arm 871 (fig. 22) and the operation of the hammer 883 operate before the cam 742 (line 14) which controls the mechanism. ratchet drive 730.

   It follows that the notch 862 of the control disc 861 (fig. 22), which has been brought opposite the corresponding feeler finger 867 by the ratchet mechanism shown in fig. 35, during the statement-balance or statement-overdraft prior to the first check entry transaction, remains vis-à-vis the finger <B> 867 </B> until after the printing mechanism has operated.



  The printing mechanism for the. second column, the one on the right, of the Flow rates part of the sheet (fig: 2), fully conforms to the mechanism just described for the first series of flow rates, with the exception that the control disc of the The reciprocating feed for the right hammer, although fully conforming to said 861 and having six notches, is placed in a relationship with the intermittent feed shaft 732- such as when one of the notches 862 of disc 861 is screwed on. -with respect to the corresponding feeler finger 867,

   a solid part of the right hammer control disc is located opposite the corresponding feeler finger for the right printing mechanism. This staggering of the discs controlled by the intermittent feed shaft 732 for the right and left printing hammers ensures the alternating operation of these hammers as long as the Checks 82 or Check Correction 83 keys are used for the registration of flow rates or rate corrections. Since the difference that we have just indicated is the only perceptible difference that there is between the printing mechanisms for the columns

  right and left of the flow section, and since it is obvious that the staggering of the discs - of the two hammers for these columns must cause the alternating operation of these hammers, one of the more extended description of the mechanism of the Check hammers are not required. Operation. The operation of the machine will now be indicated, in abbreviated form, with reference to the schematic view of the keyboard shown in FIG. 1, and the combined sheets shown in Figs. 2 and 3.

      It is customary in most banks to balance current accounts at least once a day. This operation is carried out on the combined sheet shown in Figs. 2 and 3; at the end of the month, the stub of the leaf is detached from the part that gives a. Bank statement;

   the stub is retained by the bank, while the portion of the statement is passed to the interested customer. This current account update operation includes the operations of recording old balances, subtracting debits, for example checks, bank charges, etc., adding credits, such as deposits, interest, etc. and raise the new scale.



  Let us say, by way of example, that the account of Jean Blanc has just been balanced for the previous month of December 1939. It is necessary, in this case, to transfer the balance of this old sheet to the new sheet represented in fig. 2 for the month of January 1940. The operator places the new sheet 343 on the table 335 (fig. 19) between the guide bars 345 and 346, while pushing the upper part of the sheet into contact with the stops 347 , so as to put the sheet in the appropriate position vis-à-vis the printing mechanism.

   Then, the amount of the old scale is read from the old sheet and dialed on the amount keys 71 (fig. 1) and the Carry-over balance key 88 is pressed. In the case of an active scale, the Scale Reading 84 key is pressed; in the case of a negative balance, the RL-overdraft key 79 is pressed. These two keys 79 and 84 are operator keys and are used to start the machine.



  Depression of the Balance key to be carried 88, in conjunction with one of the keys 79 or 84, engages the printing mechanism, so that the balance - say Fr. 5000.00 - is carried over to the appropriate line of two parts of sheet 343. At the same time as the report balance is printed, the date - January 1, 1940 - is printed in the Balance column of both parts of sheet 343. Pressing the Balance key to be transferred 88 print the symbol F - meaning postponed balance - to the right of the lying of the old balance. It will be seen that the reported balance is printed in a compartment provided just above the first line of the sheet.

   It will also be seen that the sheet is not advanced during this postponed balance operation.



  During the next operation, the operator dials the amount of the first debit using the amount keys 71. - Fr. 25.00 - and the. key 1 of the caller ID keys 449 (fig. 29) is pressed, after which the. Checks key 82 is pressed to start the machine. During this machine operation, the mechanism controlled by the line finder keys, and shown in figs. 25A, 25B, 26A and 26B, causes table 335 to position sheet 343 so that the first row of the sheet is in the desired position vis-à-vis the printing mechanism.

   After that, the printing mechanism prints the amount of the check, Fr. 25.00, in line 1 of the left column, i.e. the first column, of the reserved part of the sheet. at debits. During this operation also, the amount of the check, Fr. 25.00, is recorded in the check totalizer of line N 2 at the same time as it is subtracted from the old balance of Fr. 5000.00 which was recorded at the side. positive of totalizer N 1, or balance totalizer, during the balance transfer operation.



  The second of the check items - Fr. 25.00 - is composed on the keys of the amounts 71 and the. Checks key 82 is pressed to start the machine. During this operation, the amount of the check is subtracted from the amount accumulated in the balance totalizer, while being entered at the same time on the first row of the right column, or second column, of the Debits part of the sheet.

   The intermittent control mechanism shown in fig. 22 performs the operation with the hammers on the right and left in turn to print the same checks for Fr. 25.00, one in the right column and the other in the left column of the debit section. leaf. The intermittent control mechanism for the advancement of the table, shown in fig. 32, 35 and 43, controls the automatic table feed mechanism, so that the two articles in question are printed on line 1 of the sheet.



  During the following operation, the amount of the third check - Fr. 50.00 - is dialed on the amount keys 71 and the Checks key is pressed at the start of the machine operation. During this operation, the intermittent advancement mechanism of the. table moves table 335 and sheet 3-13 to the second row, after which the left hammer operates to print the check amount, Fr. 50.00, on the second row of the left column of the debits part of the sheet, while the amount of the check, Fr. 50.00, is subtracted from the balance in the balance totalizer.



  Let us say that the following article is a deposit of Fr. 100.00; . the operator dials this amount using the amount keys 71, after which he presses the Deposits key 81 to start the operation of the machine. During this operation, the deposit amount, Fr. 100.00, is printed on line 2 of the credits part of the sheet, while at the same time being added to the amount in the balance totalizer, and recorded in the totalizer scales on Ja line N 2.

   The intermittent advancement device. brings the printing of the credit or deposit to the. same line (line 2) on which the last of the checks (, that of Fr. 50.00) has been entered, as described in relation to fig. 32 to 36 inclusive, and in fig. 43 and 44.



  The three checks and this deposit represent all entries made in this account for the day in question. The account update operation is thus terminated by pressing key 74 New balance (fig. 1). During the new scale operation, the totalizer N 1 of the scales is reset to zero, and the amount recorded in the totalizer, in this case Fr. 5000.00, is printed on line 2 of the Scale part of the sheet. and the heel of the leaf. While printing this new balance of Fr. 5000.00, the date, January 2, 1940, previously entered by hand on the date device, is printed at the same time.

   Given that pressing the New Balance key 74 automatically causes the differential mechanism of the transaction row to be placed in the ninth position, 1a. cam 676 (fig. 44) prevents the operation of the advancement mechanism. Therefore, the new balance is printed on the same line (line 2) as the last of the checks and deposits. An identification symbol is printed to the right of the new scale on both sides, statement and heel, of the sheet.



  The automatic check counter, best represented in fig. 9, 10 and 11, adds 1 to the check counter wheels for each entry of a debit item. During the new balance operation, the check counter wheels, which are on line N 1, are reset to zero, and the total number of checks recorded by these wheels - in this case three - is printed between the date and the new scale on the heel of the sheet.

   At the end of the new balance operation, the mechanism shown in fig. 38 leaves the table 335 to the action of the springs, so that the table is immediately returned to the starting position, the position where it is shown in FIG. 19.



  The next update of Jean Blanc's account is made on January 3; sheet 343 for this account is placed on table 335, and the amount of the old balance, Fr. 5000.00, is entered on the amount keys. 71 (fig. 1); since this is a positive balance, machine operation is obtained by pressing the 84 Raise-balance key. During this operation, the amount of the balance; Fr. 5000.00, is recorded in the balance totalizer which was reset to zero previously.

   Since the 88 Report balance key was not used in conjunction with the Read balance key, the old balance of Fr. 5000.00 is not printed on the sheet.



  The first article, the deposit of Fr. 100.00, is then dialed on the amount keys 71, and the Deposits key 81 is pressed, so that the amount of this article is added to the balance and deposit totalisers while by being printed at the same time in the credit column of the sheet. After registering the first deposit of Fr. 100.00, the operator realizes an error and decides that the item should not have been registered.

   To correct this error, the deposit amount entered in error, Fr. 100.00, is dialed again on the amount keys 71, after which the Deposit correction key 80 is pressed to start the next machine operation, during in which the deposit amount entered in error, Fr. 100.00, is subtracted from the amount in the balance totalizer and in the balance totalizer of line N 2. Pressing: of the Deposit correction key 80 also produces the printing in the credits part of the sheet of the amount entered in error, but with the symbol EC, meaning Error correction, printed to the left of the amount.



  The amount of a second deposit, Fr. 300.00, is then dialed on the amount keys, and the Deposits key 81 is. depressed to begin the operations of the machine a. during which this deposit is carried to the balance and deposit totalisers while at the same time being entered in the credit column on the sheet.

   Since this credit is the last item to be posted to this account during this day, January 3, the operator presses the New Balance key 74 to initiate the new balance operation during which the balance totalizer is reset to zero and the amount accumulated in this totalizer is printed, with the date, January 3, in the balance column of the two parts, heel and statement, of the sheet.



  A correction of a debit, or check, entered in error, is shown as an example on line 6 (Fig. 2). In this case, the amount of the check entered in error is dialed on the amount keys and the Check Correction key 83 is pressed to begin the machine operation in which the amount of the check entered in error, either Fr. 35.00, is carried in the balance totalizer and subtracted from the checks totalizer in the second row.



  Recall that there are two addition / subtraction totalisers in row N 2 of totalisers, 1'1,1n for accumulating a total of checks and the other for accumulating a total. deposits. The debits are entered on the sheet and subtracted in the balance totalizer, while being added at the same time in the check totalizer. Likewise, credits and deposits are added up in the balance totalizer and in the deposit totalizer. In a deposit correction operation, the amount of the item to be corrected is subtracted in the deposit totalizer of line Ne 2 at the same time as it is subtracted in the balance totalizer.

   In the case of check corrections, the amount of the check to be corrected is subtracted from the check totalizer in line N 2 at the same instant as it is carried to the key balance totalizer. It is possible to print on one line of the sheet two debits, a deposit and a new balance, in the event that these entries are the only ones necessary for updating an account. This condition is shown, by way of example, on line 37 of sheet 343 (Fig. 2).

      It will be recalled, with reference to FIG. 38, that when table 335 reaches its 39'11th or last position, stud 721 swings latch 718 out of engagement with stud 717 to disengage the pawls. After the first item has been entered on the 39 "1st line, the pawl release mechanism operates to release the table 335 to the action of the reset springs, which immediately return it to the starting position. is shown on line 39 of sheet 343.

   During the January 27 update of Jean Blanc's account, the operator notes the old balance in the usual way, say Fr. 5000.00; thick he dials the amount of the first de bit, Fr. 100.00, on the amount keys, press the appropriate line finder key for the selection of the 39th line of the sheet and put. with the machine running by depressing the Checks key 82. Moving to the 391th row position, table 335 causes pin 721 to swing latch 718 to the non-operating position, as explained. above.

   At the end of the machine's operating cycle, and after printing the flow rate of Fr. 100.00, the mechanism shown in fig. 38 releases the pawls 656 and 494 to allow the table and sheet to be returned to the starting position. Before preparing a new sheet relating to this account of Jean Blanc, the operator in this case presses the selection key of the 39th line and at the same time presses key 75 controlling the sub-totalization of the new scale. (fig. 1).

   This results in a subtotal operation, in which the subtotal of the. scale, Fr. 4400.00, recorded in the scale totalizer, is printed in the scales section on the 39th line of the two parts, statement and heel, of the sheet. Pressing the Subtotal new balance key 75 causes the differential mechanism of the transaction row to be reset to zero. Referring to fig. 38, it will be seen that in this position, the raised part of the cam 723 operates to release the latch 718, so that the table 335 is released and returned to the starting position at the end of this sub-totalization operation.

   During. When the subtotal is printed on the 39th line, the pin 721 operates as before to release the latch 718. In the subtotal operation explained above, the symbol S is printed to the right of the amount of the subtotal in both parts, uplift and heel, of the leaf.

   After returning to the starting position of the table and of the sheet 343, at the end of the sub-totalization operation explained above, the operator removes the sheet which has just been completed from the table and , after inserting a new sheet 344 (fig. 3), he presses the Soi-total New scale 75 key again to print the subtotal of the old scale, Fr. 4400.00, at a point above the first line of the Balance part of both parts of the sheet. The inscriptions on lines 1 and 2 of sheet 344 represent the mode of inscription of a covered die.



  The entries on line 38 of sheet 343 represent, by way of example, the entry of a bundle of checks. In the case shown, the package includes 36 checks for a total amount of Fr. 544.00. This amount is dialed on the amount keys 71 (FIG. 1), and the LS key of the symbol keys 90 is pressed to provide the printing of a symbol indicating that this operation relates to a list of checks. The number of checks in the bundle, namely 36, is dialed on the check counter keys 52 and 72, after which pressing the Checks key 82 serves to turn the machine on.

   During the following operation, the total amount of the check list, Fr. 544.00, is subtracted from the balance and the total number of checks in the bundle, 36, is simultaneously recorded by the wheels of the check counter. . In the next operation of a new balance, the balance totalizer is emptied, and the amount that has accumulated in this totalizer is printed on the read line of the sheet and stub, so that the number of checks 36 is printed on the lifting part of the heel.

   It will be remembered that the pressing of the keys 52 and 72 of the check counter, while composing the number of checks in a bundle, disengages the automatic mechanism of the check counter; obviously running the counter during such a transaction would give im a false check total.



  All entries on the sheet and on the stub, including postponed balances, debits, credits, debit numbering and new balances, are printed in duplicate on a 906 verification tape, a fragmentary part of which is shown. in fig. 18. This duplicate entry is useful not only as a reference, but also as a means of checking your rate at the end of any period.
