Germany October 14, 1932 10 Claims.

This invention relates to improvements in printing mechanisms of the type generally shown and described in Letters Patent of the United States, granted to B. M. Shipley, Nos. 1,747,397 and 1,761,542, dated February 18, 1930 and June 3, 1930, respectively; and particularly to the carriage mechanism and control of the same to effect or not, as desired, a step-by-step shifting of the same to select the next blank line or lines upon which printing is to be done.

More specifically, the invention is an improvement relating to the mechanism shown and described in an application for Letters Patent of the United States, of Herbert Kaufmann, Serial Number 603,559, filed April 6, 1932.

One object of the present invention is to provide mechanism to control a carriage of the type shown and described in the above mentioned Shipley patents, so that after the first blank line of the printing medium has been selected by the depression of one of the line selecting keys of the carriage, the entire carriage may be shifted automatically step by step toward its normal position whereby printing may be effected in successive lines on the printing medium carried by said carriage under control of a bank of manipulative control devices.

Another object of this invention is to provide a locking device under control of special manipulative devices to render the automatic step-bystep feeding device of the carriage ineffective, thus preventing any feed of the carriage upon operation of certain of said special manipulative devices.

Another object of this invention is to provide means intermediate the above mentioned special manipulative devices and locking device, which means is set under control of said devices to prevent or permit operation of the automatic stepby-step feeding device for the carriage as desired.

With these and incidental objects in view, the invention consists in certain novel features of construction and combinations of parts, the essential elements of which are set forth in the appended claims, and a preferred form of embodiment of which is hereinafter described with reference to the drawings which accompany and form part of this specification.

General description The present invention, described in general 30 terms, involves mechanism for automatically line-spacing the record material carriages of accounting and posting machines of the type shown and described in the above mentioned Shipley Patents Nos. 1,747,397 and 1,761,542. It also involves mechanism for controlling such automatic line-spacing mechanism under control of a bank of special manipulative devices or keys.

Machines of the above mentioned Shipley type are at present extensively used in hotels to post the accounts of the guests, and also in banking institutions to post depositors accounts.

Machines are also in use which do not embody the set of ledger or account keys usually arranged at the right side of the keyboard. Such types of machines are shown in the application for United States Letters Patent of B. M. Shipley, Serial Number 42,458, filed July 9, 1925, allowed December 10, 1932, Patent No. 1,916,535, issued on July 4, 1933.

To give a general idea of how the machine is used at present, a brief explanation of an operation of the machine when posting a depositor's account in a banking institution will be given.

In making a complete posting of such accounts,

the ledger card and book are used. However, in the present case I have illustrated only a ledger card, it being thought that it is suflicient to show how the printing appears when the carriage is shifted automatically step by step on the entry of the several successive amounts of the same account. This card also shows that the first amount is printed on the same line which bears the account number, which account number may be set up by the regular amount keys, as is fully illustrated and described in the last mentioned Shipley application, Serial Number 42,458.

The teller first takes the depositors ledger card from the filing box and sets up the ledger number or account number on the amount keyboard, at the same time depressing, in the present instance the bottom one of the keys of the special bank of keys illustrated in Fig. 9, which may have the designation Account No. on the key tip. This operation of printing the account number is a separate operation of the machine. After printing the account number, the amount of the deposit or withdrawal, as the case may be, is set up on the amount keyboard and upon operation of the machine the same is printed, as for example in Fig. 10, on the same line that carries the account number printed in the previous operation.

During the set-up of the items, depending upon whether or not it is a deposit or withdrawal, a corresponding Deposit or "Withdrawal key is depressed which is allotted to the particular teller operating the machine so that such amount is properly added or subtracted to or from the old balance.

After placing the card and book in the machine the operator selects the first blank line on the card by depressing one of the line-selecting keys and moving the record material carriage to the right until it comes to a stop, which of course is controlled by the number of the key depressed. The cards have lines on them which are numbered in accordance with the numbers on. the line selecting keys.

After the several deposits have been entered, or a withdrawal subtracted from the old balance, the teller operates the usual total-taking lever to put the machine in a condition to print the new balance. During this operation the new balance is printed upon the ledger card and the depositors passbook and the computing device is cleared during such operations.

In such machines, however, the carriage remains in that position to which it has been moved by the operator upon the depression of the desired line selecting key until the new balance has been printed.

It may, however, be very desirable to list several deposits of one depositor on successive lines, for instance, currency, checks, and gold; or it may be desirable to list each of the checks being deposited on a separate line.

With the type of machines shown in the 'Shipley patents and application, it would be necessary, to accomplish such printing, for the operator. to depress a line selecting key for the entry of each one of such deposits, which of course requires a great deal of time and is somewhat of an annoyance to the operator, as it slows up his work considerably and also keeps the depositor standing an undue length of time at the window. To avoid all of this time-wasting manipulation which is also very inconvenient for the user, a novel mechanism has been provided in the instant case, which effects an automatic shift the flanges 43 of the guide 42.

of the carriage one step or one line at the end of each operation of the machine so that the next imprint is effected on the following line of the card or book respectively, with the exception of the operation during which the account number 5 is printed.

Usually the account number is printed at the beginning and therefore it is during this operation that mechanism is brought into play which will render the automatic line spacing mechanism ineffective so that it cannot funrtion during the account number printing operation, and therefore, during the next operation of the machine which operation is either the entering of a deposit or withdrawal, that deposit or withdrawal can be printed on the same line which carries the account number.

In the present case provision has been made, through the control'of the special bank of keys, to set up a mechanism which in turn controls a locking device to positively lock the automatic line spacing mechanism during the operation in which a certain one of the special control keys, in the present instance the lowermost one, is operated.

DETAILED DESCRIPTION Carriage mechanism in general Only so much of the carriage will be described as is necessary for a complete understanding of the present invention. If a further detailed description of the carriage is desired, reference may be had to the above mentioned Shipley patents. The carriage includes a plate or table 30 (Figs.

- 1, 2, 3 and 6) secured to a U-shaped frame 3| '5 having four rollers 32 running on a rail 33 fastened to a base 34. To prevent the carriage from tipping over and to retain it in a constant level position one side of the U-shaped frame 3| carries a pair of rollers 35 (Figs. 3 and 6) which 0 engage the rail 33 along the underside thereof.

To guide a ledger card (Fig. 10) (shown in dot and dash lines in Fig. 6) and a passbook ll (shown only in dot and dash lines in Fig. 6) the carriage is provided with the usual guiding means. a The book guide 42 (Figs. 2 and 6) is secured to the table 30 and has inwardly bent flanges 43. To guide the ledger card 40 a pair of flanges H are provided. which flanges are integral with As is usual, the front ends of both guides 44 are flared to facilitate the insertion of the card 40.

Normally the first blank line on the ledger card, as well as of the passbook, is printed upon. To easily set the card and book so that the printing will fall in the right place, a keyboard consisting of twenty-six keys 50 (Figs. 1, 2, 3 and 6) is arranged directly on the lefthand side of the table 30. The number of keys 50 correspond to the number of lines which are on the card and passbook, which number may be varied as the occasion demands.

After the key 50, appropriate to the line on which it is desired to print has been depressed, the carriage is moved bodily by hand to the right, until the lower end of the depressed key comes into contact with a stop.

When a key 5|! is depressed to select any one of the lines on the card, it is held in depressed position by a detent 5| (Fig. 3) of the type shown and described in the above mentioned Shipley patents. This detent is normally drawn to the right by a spring 52.

The above mentioned stop with which the depressed key is adapted to contact to stop the carriage in the proper position includes a pair of hinged plates 53 and 54, pivotally supported by flanges 55 (only one of which is shown) extending upwardly from a slidable bar 58. Each plate 53 and 54 has a stud 51 connected by a spring 58. This spring 58 tends to rock the plate 53 counterclockwise and the plate 54 clockwise. The movements of these plates are limited by a pair of studs 59 (only one of which is shown) secured to the slidable bar 58.

In Fig. 3 the carriage 38 is shown in its righthand position. Assuming that one of the keys 58 is depressed, the operator manually moves the carriage toward the left whereupon the lower end of the depressed key strikes the plate 54, rocking the same counterclockwise until said lower end of the depressed key strikes the plate 53, whereupon the carriage is stopped. Upon the contact by the key with the plate 53, the plate 54 then snaps upwardly under the action of the spring 58, thus locking the key between the two plates, which consequently locks the carriage in the position to which it has been set.

In Figs. 1 and 2 the carriage 38 is shown in position to print on line H of the card and book.

The normal position of the carriage table 38 is at the extreme left, just the reverse of the position in which it is shown in Fig. 3. When the carriage is moved by hand from the left to the right to select the first blank line to receive the printing. then the depressed key 58 rides over the plate 83 and comes to a stop against the edge of the plate 54. Then the plate 53 snaps upwardly to its normal position, thus locking the carriage in its selected position.

K ey release As is fully explained in the above mentioned Shipley patents, after the taking of the new balance the detent 5| is moved toward the left (Fig. 3) thus releasing the depressed key whereupon a heavy spring 88 restores the carriage to its normal lefthand position.

Upon the taking of the new balance in the machine of the type with which the present invention is used, it is well known that such machines make two cycles of movement during such balancing operations. It is also well known that the printer shaft, shown at 8| (Figs. 1 and 2) herein is idle during the first of such cycles of movement but receives one counterclockwise rotation during the second cycle thereof.

It is through the medium of this shaft 8| that the depressed line selecting key is released. Such mechanism will be but briefly described herein. For a more detailed description and illustration reference may be had to the previously mentioned Shipley patents.

Cooperating with the key detent 5| (Figs. 3 and 4) is a release bar 82 (Figs. 2 and 5) mounted by means of angular slots 83 on studs 84 carried by lugs 85 extending downwardly from the carriage frame. Contacting the underside of the bar 82 is a pin 88 carried by one arm of a bell crank 81 secured to a short shaft 88 (Figs. 1, 2 and 5) mounted in a bearing 89 supported on a lug 18' of the base 34.

Also secured to the shaft 88 is an arm 8 (Figs. 1 and 2) forked to embrace a stud 8| of an arm 82 slidably and pivotally mounted on a shaft 83 (Fig. 2) supported by the printer front frame 84 and a bracket (not shown) carried thereby. The arm 82 is connected by a ball 88 to an arm 81 also freely mounted on the shaft 83. A spring 88 maintains the parts normally in the positions shown in Fig. 1.

The printer shaft 8| has secured thereto an arm 89 in the path of the arm 81. Therefore, the arm 89 upon the counterclockwise movement of .15 the shaft 8| rocks the arms 81 and 82 clockwise, and the stud 8| rocks the arm 88, shaft 88 and bell crank 81 counterclockwise, whereupon the pin 88 (Fig. 5) raises the bar 82. Due to the angular slots 83 the bar 82 also moves to the left 10 and shifts the detent 5| far enough to release the depressed unlatched key 58. When the arm 89 passes on the arm 81, the spring 88 lowers the pin 88 and the spring 52 restores the detent 5| and bar 82 to normal position. The spring 88 15 also returns the arms 88, 82 and 81 to their normal positions.

Attention is called to the fact that in the Shipley structure previously referred to the line selecting key 58 is not released during adding go or any single cycle operations, since during such operations the arm 81 is out of the path of the arm 89 on the printer shaft as is fully set forth in the patents above mentioned.

Shock ab'sorber When the carriage is moved either by hand or by the spring 88 to any of its selected positions or to its normal position, respectively, there will be a certain amount of shock when the carso riage comes to a certain stop. Therefore, means is provided for absorbing this blow so as to prevent any damage to the mechanism.

The previously mentioned bar 58 (Fig. 3) is slidably mounted on studs 98, carried by the rail 33. The right end of the bar 58 is formed with a. downwardly projecting flange 9| to guide and support a screw stud 92, screwed into a bracket 93 secured to the rail 33. A pair of lock nuts 94 holds the screw stud 92 in any position to which it is adjusted. A compression spring 95 is located between a washer 98 and the head of the screw stud 92, and another compression spring 91 surrounds the screw stud 92 between a washer 98 and a collar 99 pinned to the stud. 5 When the carriage 38 is moved to the right rapidly by the operator when adjusting the same to select a particular line, and the key 58 strikes the plate 54 the shock of such stop will be absorbed by the spring 95. 50 When the carriage 38 is moved to the left by the spring 88 with no key 58 depressed, a pin I88, carried by the carriage 38 contacts the right end of the flange 55 to stop the carriage in its normal position. At this time the shock is absorbed by 55 the spring 91. When the carriage is moved to the left with a key 58 depressed, the depressed key stops against the plate 53, then the shock of stopping the carriage is also absorbed by the spring 91. 60

Printing mechanism Automatic line-spacing mechanism 70 As has been prevously stated at the outset of this specification, it may be desirable to enter the several items of a single item transaction in lieu of the sum thereof as a single item. For 75 will be printed on the next line.

example, when the machine is being used in a banking institution several separate credits of a single transaction may be entered one after the other, such as illustrated in Fig. 10.

Therefore, in order to do away with the former necessity of manipulating the keyboard by the depression of one of the line selecting keys 58 for the entry of each of such items, the present invention provides mechanism for automatically t'abulating or shifting the carriage one line at the end of each item-entry operation of the machine so that the next imprint is effected on the following line of the card or book, respectively, or both, as is desired.

During the first of such item-entry operations the depressed line selecting key 58 will be released and the carriage 38 will be automatically spaced one step by means to be later described, so that on the subsequent item-entry operation the item The carriage is thereafter shifted one space upon the entry of each subsequent item, but there will be no key released since none is depressed for such subsequent items of the same transaction.

It might be well to state here that in connection with this automatic shifting or line-spacing of the carriage, the present invention also contemplates a control over the automatic shifting under certain conditions, which controlis effected by certain of the manipulative devices in thespecial or control bank in the machine of the type with which the present invention is adapted to be used.

.Such control over the automatic line-spacing or carriage shifting mechanism will be later described in detail under a separate heading.

The automatic carriage spacing or shifting mechanism per se will now be described. Pivoted to the bell crank 81 (Figs. 1 and 2) is a link I48 carrying two pins I II projecting through a slot I42 of a link I43. The link I48 also carries a spring stud I44 and the link I43 carries a spring stud I45. A spring I49 normally holds the links in the positions shown in Figs. 1 and 2. The purpose of this flexible connection between the two links will be hereinafter explained. The link I43 is supported at its right end (Figs. 1, '7 and 8) by a stud I41 carried by an L-shaped bracket I48 secured to the base 34. This link I43 also carries a roller I58 adapted to cooperate with the upper left corner of a plate II pivoted on a stud I56 carried by the bracket I48. A spring I53 tends to rock the plate I5I counterclockwise, always maintaining it in contact with a stud I54 of the bracket I48.

Pivoted on stud I55 carried by the plate I5I and on stud I56, are pawls I51 and I58, respectively. These pawls are under the action of a spring I 59 coiled about the stud I52. The spring I59 always tends to rockthe pawls I51 and I58 in counterclockwise direction, which movement of the pawls is limited by the studs I68 and IEI, respectively. These pawls I51 and I 58 are adapted to cooperate in a manner to be later described, with a notched bar I18 secured by studs III (Fig, l) to the frame 3|.

Let it be assumed that the carriage has been moved manually to the positions shown in Figs. 1 and 2 and that there are a plurality of items relating to the transaction to be recorded and that this transaction consists of several credits to be entered in connection with an account numbered 132,674. These credits are to be recorded on the record material but in different lines, the

desired line selecting key 58 is depressed and the carriage is shifted by hand until it occupies accurately the selected position shown, in which the first impression is made. The first operation consists of setting up the account number 132,674 on the regular amount keyboard and printing that account number as shown in Fig. 10. During this operation the automatic line-spacing mechanism is rendered ineffective by means to be later de scribed, or in other words controlled so that it will not automatically line-space during the operation in which the account number is set up and printed. Therefore, for the present we will pass over that particular operation of the machine and go to the second operation wherein the operator sets up the first credit, which in the present instance is shown as $33.50.

During the entry of the inst credit item or $33.50 the printer shaft BI is, as has been previously described, located once in a counterclockwise direction. During such movement of the shaft 8I (Figs. 1 and 2) the arm 89 strikes the arm 81, rocking the same clockwise, which through the stud 8| rocks the arm 88, shaft 68 and the bell crank 81 counterclockwise, thus moving the links I48 and I43 toward the right.

It will be recalled that these two links are connected by the spring I49 and therefore when the 7 link I48 is moved toward the right the link I43 is, under the influence of the spring I49, moved likewise. Upon such movement the roller I58 by its contact with the upper left corner of the plate [5| rocks the same clockwise about the stud I58. This clockwise movement of the plate I5I through stud IGI, effects a disengagement of the pawl I58 from the notched bar I18 and causes the pawl I51 to engage the notched bar I18. The nose of the pawl I51 enters the notch, opposite the same, in the bar I18 before the nose of the pawl I58 is entirely withdrawn from its associated notch. The pawl I5! is located to arrest the carriage 38 after it has moved less than a line space. As soon as the nose of the pawl I58 leaves its notch, the spring 68 draws the carriage '88 toward the left just a portion of one tooth or line space, until the right side of the wall of the notch entered by the nose of the pawl I5'I strikes said nose thus preventing further movement of the carriage in this instance. The pawl I5'I therefore holds the carriage in the partially line spaced position.

Now, when the arm 89 passes off the arm 81, the springs 88 and I53 restore the arms 81, 88, bell crank 61, links I48 and I43, and plate |5I to their normal positions. Thus, the pawl I58 is again engaged with said notched bar I18 at the same time that the pawl I51 is disengaged therefrom. As the pawl I51 leaves the notched bar I18 the spring 68 shifts the bar and the carriage 38 the remaining part of the line space until the nose of the pawl I58 arrests said bar, at which point the card and book are in position to receive the print on the next line.

From the above it can be clearly seen that the notched bar I18 and the carriage 38 are automatically spaced one step toward the left, thus bringing the subsequent'line on the ledger card 48 into printing position opposite the type wheels I88.

The operation set forth above may be repeated until all of the credits to be entered into one account have been printed on the ledger card and in the pass-book, if such is desirable.

After all of the credits and debits if there are any, have been entered as above described, the new balance is taken, which operation is a total operation, which in the machines of the class to which the present invention is applied, as is wellknown, requires two cycles of movement.

It is also well known that the printer shaft 6| does not function during the first of said two cycles; consequently the carriage is not shifted Temporary release for automatic shifting means If desirable, the operator may release the pawl I58 from the notched bar I10 thus allowing the spring 80 to restore the carriage 30 to its normal lefthand position at any time that it is desired to do so.

To accomplish this result the machine is provided with a handle or lever I13 (Figs. 1, 2 and 6) secured to a shaft I14 carried by the front flange of the frame 3| and a plate I16 secured to the rear flange of the frame 3I. Also secured to the shaft I14 is an arm I11 having connected thereto a link I18 which in turn is connected to a slidable bar I19. This bar I19 has diagonal slots I80 into which project studs I8I secured to the notched bar I10. The plate I19 is adapted to be moved toward the left by a spring I82.

Depression of the lever I13 by the operator rocks the same and the shaft I14 and also the am In counter-clockwise, thus moving the link I18 and plate I19 toward the right. Due to the diagonal slots I80 the plate I19 is also lowered, and through its contact with a stud I83 carried by the pawl I58, said pawl is rocked clockwise,

thus disengaging it from the bar I10 whereupon on the lever I13 the spring I82 restores the parts I19, I18, I11, I14 and I13 to their normal positions and at the same time the spring I59 rocks the pawl I58 counter clockwise, thus reengaging the same with the notch in the bar I10 now out of said pawl.

Control of automatic spacing mechanism As previously stated, it is customary when entering the several debits or credits of a single transaction that-the account number be printed first. Such an illustration is shown in Fig. 10 wherein the account number 132,674 is shown printed in the righthand column. This account number, as previously stated, is set up on the regular amount keys. A special key having a designation such as Account No." is placed in one of the banks of special or control keys, such as shown in the above mentioned Shipley Patent No. 1,916,535.

It is during this operation, that is, the operation which prints the account number, that it is highly desirable to render the automatic feeding or shifting mechanism of the carriage ineffective and maintain the carriage in a position so that the first debit or credit, as the case may be,

will be entered on the same line that the account number is printed on.

The mechanism for so disabling the automatic line-feeding mechanism is shown in Figs. 1, 2, '1,

8 and 9 and will now be described. 5

A shaft 200 adapted to be adjusted by a differ ential device of a special key bank, to be hereinafter described, has secured thereto a disk 20I carrying a pin 202 adapted to cooperate and control a lever 203 pivotally mounted onv the end of a shaft 204 supported near its front end by the printer front frame 84 and near its back end by the printer back frame (not shown). This lever 203 is normally held in the position shown in Figs. 1 and 7 by a spring 205. The left end of the lever 203 has a slot 206 into which projects a pin 201 carried by a pawl 208 pivoted on a stud 209, to which the previously described spring I53 is attached. This stud 209 is carried by the bracket I48. The right end of the pawl 208 has 20 a hook 2 I adapted to cooperate with a stud 2I I, to which the other end of the spring I53 is attached. This stud 2I I is carried by the plate II, which it will be recalled carries the pawls I51 and I58.

When the disk I and pin 202 are in the positions shown in Figs. 1 and 7 the automatic linespacing or carriage shifting mechanism functions in the normal way so that for each successive operation the printing will be effected upon the succeeding line.

However, when the disk 20I and pin 202 have been moved into the position shown in Fig. 8 through the medium of the differential mechanism under control of the special bank of keys to be hereinafter described the movement of the disk 20I from the position shown in Fig. 7 into the position shown in Fig. 8 through the cooperation of the pin 202 with the right end of the lever 203 rocks the lever clockwise whereupon 0 the pin 201 rocks the pawl 208 clockwise and the hook 2 I0 engages the stud 2| I as shown in Fig. 8.

With the parts in these positions, when the shaft BI is rotated counter clockwise in the manner previously described, which shaft rocks the 5 arms 81, 82, lever 80 and bell crank 81 so as to move the links I40 and I43 toward the right, the fact that the hook of the pawl 208 is holding the plate I5I, the movement of the link I40 toward the right merely stretches the spring I49 as the 50 link I43 at this time cannot be moved since the plate I5I is prevented, by the pawl 208, from any movement.

Therefore, it can be clearly seen that when the special key in the control bank has been depressed to control the positioning of the disk 20I so that the latter will set in the position as shown in Fig. 8, the automatic line-spacing or carriage shifting mechanism is positively disabled.

It might be well to state here that the spring 80 I49 must of necessity be stronger than the spring I53 so that when the pawl 208 is not in engagement or in cooperation with the stud 2I I the movement of the link I40 toward the right will, through the spring I49 move the link I43 like- 85 wise, overpowering the spring I53 and rocking the plate I5I to effect the automatic line-spacing of the carriage 30.

During the subsequent operation of the machine, that is, during that operation in which 10 either the first debit or credit, as thecase may be, is entered, a diiferent key of the hereinafter described control bank is depressed whereupon the disk 20I during the movement of the differ-; ential mechanism will assume a different position than that shown in Fig. 7, the position assumed being in accordance with the position of the key which has been depressed, and the spring 205 will rock the lever 203 counterclockwise from the position shown in Fig. 8 to that shown in Fig. 7 whereby the pin 20! will immediately rock the pawl 208 counterclockwise, thus disengaging its hook 2) from the stud 2 so that during this operation, upon movement of the links I40 and 10 I43 toward the right as viewed in Fig. l, the plate l5l will be rocked in the usual manner to effect the automatic line-spacing of the carriage 30.

Control of arutomatic line-space disabling mechanism In Fig. 9 there is shown a differential mechanism adapted to be controlled by a bank of keys to determine the positioning of the previously described shaft 200 and disk 21.

Key bank The special key bank for determining or controlling the positioning of the differential mechanism shown in Fig. 9 is of the usual type shown and described in the above mentioned Shipley patents and application and therefore will be but briefly described in this case. There are eight keys 220 of the usual control type and for the purposes of illustrating this case, one special key 221 bearing the caption Account No.. This latter key, for the purpose of illustration in this case, is shownin the first position. These keys 220 and 22f are carried by the usual key frame 222 supported on rods 223 which rods are in turn 35 supported by the side frames 224 of the machine (only one side frame being shown). Keys 220 and 22I are each provided with a pin 225 adapted tocooperate with a retaining detent 226- only partially shown in this case. The usual zero stop pawl 22! is shown in a position to stop the differential mechanism, to be hereinafter described, in the zero position. However, when any one of the keys 220 or 221 is depressed the zerostop pawl through the detent 226 is moved into an in-- effective position in the usual manner.

Difierential mechanism The differential unit associated with bank ofspecial keys is supported by the usual hanger P 233 mounted on rods 23f and guided at its top end by the key frame 222. Pivoted on a hollow stud 232 supported by the hanger 230 is a differentially adjustable arm 233 carrying an arm 234 and a bell crank 235, which in turn supports the usual type of latch 236 having a foot 23'! held in contact by a spring 239 with a shoulder on a driving segment 238. This driving segment 238 is pivoted on the stud 232 and is connected by a link 24!! with a Y-shaped lever 24I pivoted at 242 to the hanger 230. This lever 24lcarries a pair of rollers 243 cooperating with a pair of cams 244 secured to a main drive shaft 245.

Pivoted at 246 to the differentially adjustable arm 233 is the usual beam 241 having its other 65 end slotted to embrace a stud 248 carried by a link 249 the lower end of which is pivoted to an arm 250 secured to a spiral segment 25I meshing with a spiral pinion 252 secured to the previously described shaft 200.

The upper end of the link 249 is connected to the usual alining segment 253 having cooperating therewith the usual aliner 254.

If none of the keys 220 or 22I is depressed, the zero stop pawl 22! will in the usual manner 75 cause the differentially adjusted arm 233 to be stopped and disconnected from the driving segment 238 in the zero position upon movement of the segment 238 by the lever 24| and cams 244;

Let us assume that the account number key 22l is depressed and the machine started through 4 its operation. In this instance the latch 236 by the cooperation of the front end thereof in the usual manner with the inner end of the depressed key 22l will be disengaged from the driving segment 238 as it is being rocked clockwise to by the lever 24I and cams 244. As the arm 233 is stopped in the first position the left end of the beam 241 will be likewise stopped in that position and as the lever 24I nears the completion of its clockwise movement a roller 255 carried thereby 15 will contact the underside of the beam and position it in the usual manner, whereby its right end through the stud 248 will lower the link 249 and rock the arm 250 and spiral segment 25| clockwise, which in turn through the spiral pinion 252 will rock the shaft 200 and disk 20I to move said disk from the position shown in Fig. 7 to that shown in Fig. 8. Near the end of the operation of the machine, as the driving segment 238 is being restored to its normal position it will 25 contact a stud 256 carried by the differentially adjustable arm 233 and restore that arm to its normal position shown in Fig. 9. However, the right end of the beam 24! and consequently the link 249 and disk 20 I will remain in the positions to which they were set at the end of this operation and until this differential mechanism assumes another position under control of either the zero stop pawl 22'! or one of the keys 220.

From the above description it can be clearly seen that the automatic line-spacing or carriage shifting mechanism is directly under control of the keys of the special bank shown in Fig. 9. In other words when, in the case as illustrated, the key 22| is depressed the automatic line-spacing 40 mechanism is disabled but when any of the other keys 220 are depressed, the automatic line-spacing mechanism functions in the usual manner. It might be well to state here that the positionof the key 22I may vary in accordance with the position of the pin 202. In other words, if it is desirable to have the upper key 220 control the disabling of the automatic line-spacing mechanism' then the pin 202 would be located accordingly on the disk 201.

Since the operations of the various mechanisms have been fully and clearly described under their separate several headings it is thought that it is unnecessary to give any detailed description of a complete operation at this time.
