Claims.

The invention relates tol cash registers and the like machines and more particularly to a printing mechanism for such machines which is adapted to selectively effect a variable number of im- 5 prints on various record materials by a printing hammer coacting with a plurality of groups of type wheels, including a group of amount type wheels. In such printing mechanisms, column selection has to be provided for, since certain l0 kinds of entries require imprints of the data and -amounts to be entered in separate columns on the said record materials.

Heretofore in column selection mechanisms, either the amount type wheels-see, for example,

U. S. A. Letters Patent No. 1,311,884 to Fuller-or the data type wheels and the printing table have been shiftably arranged. Such arrangements result in a complicated structure of the printing mechanism due to the shifting and controlling device necessary for at least one of the groups of type wheels.

Thus the main object of the present invention is to enable column selection with al1 the groups of type wheels arranged stationary.

Another object of the invention is to provide for simultaneous and successive actuation of printing hammers coacting with the various groups of type wheels.

Another object of the invention is to arrange means for properly shifting the printing table between successive printing hammer strokes.

Another object of the invention is to adapt the printing table shifting means for varying the extent of table shift.

Still another object of the invention is to arrange means for controlling the table movements in accordance with a transaction performed.

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

General description The invention is herein shown embodied in a cash register provided in a well known manner with a printing mechanism in which the printing hammers are actuated a plurality of times during a machine operation in order to make the same impression on several record materials which are inserted into the machine. Such machines provided with the novel arrangement are installed in a cashiers window of a savings bank, or the like establishment, especially in a small branch oice of it, where, due to the small number of customers and the low amounts handled, an installation of a posting or accounting machine may not be economical.

In such a case, record materials to be imprinted upon comprise an insertable deposit slip, a ledger card and a pass book. The deposit slip, of the kind shown in Fig. 15, is filled in and duly signed by the customer and handed to the cashier together with the pass book. After having secured the customers ledger card, of the usual type as shown in Fig. 14, the cashier first inserts the deposit slip, then the ledger card and then the pass book, to have the same data such as the date, consecutive number, ledger number and amount of the transaction, i. e. of the deposit or withdrawal as well as a symbol for signifying the amount, W for Withdrawal and D for deposit, printed thereon by the machine. Such small machines are usually not provided with an add and subtract or balance totalizer. Therefore when such la machine is used for the purpose above outlined, the new balance to be obtained from an old balance of an account and a deposit or withdrawal is not calculated by the machine, but by the cashier, who has to set up the new balance on the amount key board and operate the machine in order to have the new balance printed on all the three record materials.

With such accounting it is essential that the forms oi' ledger cards used in the branches and in the central oilice be the same. 'Ihis Is the more important, as the receipts have to be sent to the central olce, to have the customers main ledger cards properly made out. Only the duplicates are kept in the branch ofllces. In order to obtain identical imprints in the central office, by the highly efllcient accounting machines, and the small machines installed in the branch ofiloes, the latter are provided with the novel column selecting device according to the invention which is fully described hereinafter.

The machine in which the invention is shown embodied may be either electrically or hand operated. Such machine is provided with the usual ledger number keys and amount key banks (both not shown), the amount keys being used to enter amounts into the machine, which are, as the case may be, either deposits or withdrawals, and credit or debit balances. The key board further comprises a bank of transaction keys II, I2l and I3, of which the key II serves for deposit entries, the key I2 for withdrawal ones and the two keys I3 for credit and debit balances respectively. These transaction keys control, in addition, the selection of totalizers proper (not shown) into which the amounts set up on the amount key banks are entered, and also the machine release mechanism, which is provided with a well known automatic stopping device for interrupting machine cperation before completing its cycle. Such an automatic stopping and releasing mechanism is shown and described in U. S. A. Letters Patents Nos, 1,658,993 and 1,991,560 to Kmmling and No. 1,761,572 to Kropfl, to which reference may be had for a more detailed description.

In addition, these keys control the adjustment of a type wheel to print symbols (W, D, NC, ND) corresponding to transaction keys depressed.

The printing mechanism, as shown and described, comprises, in addition to the beforementioned type wheel and a group of amount type wheels, at least one group of type wheels for printing the date, another for the consecutive number, and still another for the ledger number. A printing hammer coacts with the date, consecutive number, and ledger number type wheels, and another printing hammer coacts with the amount group of type wheels and with the symbol type wheel. In accordance with the transaction keys depressed at the time, said hammers are actuated singly, simultaneously or successively, in the manner hereinafter described.

Special keys 'I'he special keys II, I2 and I3 (Figs. 1, 3, and 4), which function as transaction and machine release keys, are slidably mounted in a key frame 24 carried by

rods

25 and 26 supported at their ends in the side frames of the machine. The keys II, I2 and I3 carry laterally projecting studs I5, I1 and I8, I9 respectively, which, when said keys are depressed, coact with the inclined slots 20, 2|, 22 and 23 in a detent I5 and rock the latter upwardly against the action of a spring I4. The detent I5 is supported at both ends by a bifurcated portion thereof embracing a stud 21 and28, respectively, carried by the frame 24, while at its upper end it is pivotally connected to a zero stop pawl 29 pivoted on a stud IIB in the frame 24. Thus whenever the detent I5 is rocked upward in the manner just described it will rock the zero stop pawl 29 clockwise (Fig. 4) to an ineffective position.

Another detent I|0 (Figs. 1 and 4) oi an old and well known type, which cooperates, as will be specli'led below, with'the release and stop mechanism, retains the keys Il, I2 and I3 in their depressed positions until near the end of the operation of the machine, when said detent is caused to release the keys to the action of coiled springs (not shown) which return them to their normal undepressed positions. When this occurs the spring I4 then returns the detent I5 downwardly to its home position and, at the same time, moves the pawl 29 counter-clockwise to its normal eifective position.

There are arranged in this key bank four other detents I5| to |54 and also a detent 24U, the function of which will be described later in connection with the printing mechanism..

Dierential mechanism 'I'he differential mechanism associated with the special keys Il, I2 and I3 adjusts means for controlling operation of the machine, as will be hereinafter described. Such a differential mechanism is well known in the art and specified in the U. S. A. Letters Patent No, 2,139,719 to Breitling et al.

This differential mechanism includes a differentially movable actuator 30 (Figs. 3, 4 and 5) which, through a latch 3| pivoted thereon, is driven first counter-clockwise (Figs. 3 and 5) and then clockwise during each operation of the machine by a driving segment 32 fast on a shaft 33 journalled at its ends in the side frames of the machine. A foot 34 on the latch 3| is constantly held in cooperative relation with the periphery of the segment 32 by a spring 35. The driving segment 32 receives a constant excursion of movement, rst in a counter-clockwise direction and then in a clockwise direction, during each operation of the machine by means hereinafter described.

As the segment 32 is thus rocked counter-clockwise the foot 34 of the latch 3| will, near the end of such movement, be rocked into engagement with a shoulder 36 on said segment by the spring 35. Then as the segment 32 is returned clockwise to its home position it will, through the engagement of the shoulder 35 with the foot 34, carry the latch 3| and the actuator 3U along with it until a resilient pawl 31 on said latch strikes either the zero stop pawl 29 or the stem of a depressed key II, I2 or I3. When this occurs the pawl 31 is thereby rocked counter-clockwise and causes the latch 3| to be rocked likewise. This disengages the foot 34 from the shoulder 36 and. at the same time, engages a locking projection 38 on said latch with one of a series of notches 39 in a locking plate 40 attached to the frame 24. The actuator 30 is thus locked in its moved position, while the segment 32 continues its counterclockwise movement until it reaches its home position.

Secured to a main drive shaft 50, suitably journalled at its end in the machine side frames, is a cam 5| (Figs. 1 and 3) having a cam groove 66 coacting with a roller 61 on an arm 69 pivotally mounted on a rod 68 suitably supported in the machine. The shaft 50 and cam 5| receive one complete rotation in a counter-clockwise-direction (Fig. 3) .upon each operation of thc machine. When this occurs, the configuration of the groove 88 is such that the cam 5| will rock the arm 89 first clockwise and then counter-clockwise during each operation of the machine. The arm 89 has formed integral therewith a toothed rack I meshing with .a segment 1I secured to the shaft 23. It will thus be apparent that when the cam 8| rocks the arm 89 in the manner just described, the latter will, in turn, rock the gear 1|, shaft 33 and driving segment 32 lrst counter-clockwise and then clockwise.

The differentially movable actuator 30 is returned to its home position during the next succeeding operation of the machine by the surface 43 on the segment 32 coacting with the stud 44 on said actuator when the segment is rocked clockwise.

Machine stoppage and release device For starting machine operation either the deposit key II or the withdrawal key I2 or one of the two balance keys I3 (Figs. 1 and 4) has to be depressed. Upon depression of one of these three keys, its pin I8, I1, I8 or I9 respectively, coacts with an inclined slot III, II2, |I3, |I4, respectively, associated therewith in a detent IIO rockably arranged on the studs 21 and 28 and rocks this detent ||0 downwardly. Thereat, a shoulder II9 of the detent |I0 frees a projection |20 arranged on an arm II9 pivoted on a stud I|8 and connected by means of a rod |2I to the one arm |24 of a bell crank lever mounted on a machine release shaft |22. The other arm |25 of the lever embraces by its bifurcated end a stud |28 of a clutch control lever arm |28 rockably arranged on a shaft I2'I. The control lever arm |28, the end of which cooperates with a projection |32 of a clutch disc I3I, is connected by a sleeve to a clutch member |29 loaded by a strong spring |30. The disc |3I rotatably arranged on the machine main shaft 50 is connected to a gear |34 engaging a pinion |38, mounted on a shaft |35. When the machine is operated by means of an electric motor the clutch disc I3I forms a part of the driven member of a clutch mechanism on the machine main shaft 50.

On the arm II9 a spring actuated pawl |38 is rotatably arranged which is forced by its spring |39 in the path of the shoulder I|8 of the detent |I0 If now one of the transaction keys II, I2 or I3 is depressed, and the detent |I0 is moved downwardly, the shoulder II8 pushes the pawl |38 aside .against the action of its spring |39. As simultaneously the shoulder II8 leaves the path of the projection |20, the spring |30 becomes effective and rotates the arm II9 clockwise. Thereat, the projection |20 is moved above the shoulder |I8 and prevents restoration of the detent I I0 under the action of its spring |40 and also of the depressed transaction key. Fuiather, the clutch control lever arm I 28 is disengaged from the projection |32 of the clutch disc I3| and, by the spring |30, the arm |29 is rocked into the path of pins |42, |42 and |42" on a gear |4| mounted on the main shaft 50 and meshing with a gear |43 rigidly connected to the pinion |38. The ratio of the gearings is such that the disc I3| is rotating through two full revolutions, when the gear |4I, and thus the main shaft 50, is making one revolution.

I2 or I3.

In this manner the machine is locked at all events after half a revolution of the main shaft, and this locking takes place after the first operation of the printing mechanism. The operator now inserts the second record material to be imprinted into the machine, and presses once more the same transaction key II, I2 or` I8 to release the machine. This second revolution extends, however, only to 90 of the main shaft revolution. After this part-revolution, the pin |42' engages the arm |29 and forces the clutch member |28 into the path of the projection |32' of the locking disc 3|. Likewiie, in the manner already described, the depressed transaction key is released again. Now, the third record material is inserted into the machine, the same transaction key is depressed, and the machine is operated the third time, until the pin I 42" finally stops the machine.

In order to force the machine operator to depress for each part-revolution the same transaction key II, I2 or I3 with which he started machine operation, in the transaction key bank four more detents I| to |54 are provided (Figs. 1 and 5), each one having an inclined surface and a plurality of locking surfaces, which cooperate with the pins I6', I'I', I8', I9 of the transaction keys II, I2, and both the balance keys I3 respectively. By depressing one of the keys, say II, the pertinent detent I5I is lifted, whereby the other keys II and I3 are locked. In the same manner the keys II and I3 are locked by means of the detent |52 upon depressing the key I2. The upper end of each of the four detents I5I to |54 has a hook projection |55 to |58 which, when the detent moves upward, engages from behind the projection |80 of an arm |8| of a bell crank rotatably mounted on a shaft I 85, the other arm |82 of which is spring actuated and has a working surface |64 cooperating with a square pin |86 of a pitman |83. The pitman |83 is guided by the shaft |35 projecting into an elongated slot |88 of it and actuated by a cam |89 fast on the main shaft 50. The cam |89 cooperates with a pin |10 of the pitman |83. The bifurcated end of the pitman |83 embraces the shaft 50.

This arrangement for making it necessary to depress the same key for a number of successive operations is Well known in the art as may be taken from U. S. A. Letters Patent No. 2,116,779 to Breitling to which reference may be had for a more detailed description.

Printing mechanism In the printing mechanism there `are arranged one set of type Wheels 200 for the date printing, one set for printing the consecutive number, one set 202 for the ledger number and one type Wheel set 203 for the amounts and a type wheel 204 for the symbols (Figs. 1, 6, 12 and 13) vet The type wheel sets 202 to 204, mounted on the shaft |02, are differentiated by gearing: |03 to actuated by the associated diiferentials (Figs. 3 and 12), whereas the type wheels 20| for the consecutive number are adjusted by a device which will be described later. The date type wheels 200 are set by hand by means of the knobs |3I. The arrangement is well known in the art wherefore no detailed description is deemed necessary.

An impression hammer 206, freely mounted on a shaft 201 (Figs. 2 and 6), is common to and cooperates with the type wheel sets 200 to 202. The hammer 206 contacts by its stud 208, due to gravity, an actuating lever 209. The lever 209, pivotally mounted on the shaft 201, has a roller 2I0 coacting, under the action of a strong spring 2| I, with the periphery of a cam member 2|2 secured to a shaft 2| 4 driven by the main shaft 60 through a train of gears 2|6, 2|6, 2|1, 2I8 and 2|9 (Figs. 1, 2 and 6). Thus rotation of the shaft 2I4 is stopped whenever the main shaft 50 is arrested after a part-revolution of 180, 90 and 90 as explained above. The cam member 2|2 comprises three lobes 220, 22|, 222 (Fig, 6) by one of which the impression hammer 206 is actuated during one of the three partial operations, to print on the record material at the time inserted, the date, the consecutive number and the ledger number.

A separate impression hammer 226 (Figs. 1, 2 and 6) is provided for the amount type wheel set 203 and symbol type wheel 204, which hammer is driven by a lever 228 actuated by a cam member 23|. 'I'he cam member 23| also comprises three

lobes

232, 233, 234, the first one 232 actuating the hammer 226 at the same time as the first lobe 220 of the cam 2|2 does the hammer 206, while the two remaining

lobes

233, 234 of the cam member 23|, being staggered on the shaft 2I4, are rendered effective at a later instant than the corresponding lobes 22|, 222 of the cam member 2|2. Due to this arrangement of the hammer driving cam lobes, the two impression hammers 206 and 226 operate at the same time during the first partial operation, whereas during the second and third partial operations, the Wide impression hammer 206 operates first and, some time later, the amount impression hammer 226 operates. In that way after an impression of the date, consecutive and ledger number is taken, the record material inserted can be shifted to the desired amount co1- umn wherein the amount is to be printed (compare Figs. 14 and 15). 'I'he column to be imprinted among the three columns provided is determined by the kind of transaction, that is, whether the amount is a deposit, a withdrawal, or a balance. Consequently column selection is controlled by one of the transaction keys II, I2, I3 (Figs. 1 and 3) as described below.

For column selection the printing table has to .be shifted in the interval between the various hammerstrokes. The mode of shifting is determined by the transaction key depressed. For that purpose the before mentioned key detent 240 (Figs. 1 and 3) is provided in the transaction key bank. The detent 240 is normally held in its upper position by a spring 24|. The detent 240 is provided' with slots 242, 243, 244, 245, the form' of. which determines the kind of coacting with the key pins I6', I1', I8', I9', in such a way that the detent 240 is not moved at all by theidepression of the deposit key II, while it ismoved by one step upon the depression accessi of the withdrawal key I2 and by two steps upon the depression of each of the two balance keys' I3.

The detent 240 is connected by a crank. lever 246 and a link 241 to an arm 248 pinned to a shaft 250 (Fig. 3). A pin 249 of the arm projects in an elongated slot 249a of the link 241. The object of this arrangement will be to permit restoration of the detent 240 and to permit a transaction key to be depressed after a part machine operation without changing the adjustment of said shaft 250 effected by the said transaction key originally depressed. The other end of this shaft has fixed thereto an arm 25| the stud 262 of which engages a grooved sleeve 263 (Figs. 2 and 7). The sleeve 253 is shiftably but unrotatably mounted on a shaft 255 and is normally held in its left hand end position by a spring 256 (Fig. 7). 'I'he sleeve 253 is integral with an arm 251 having a roller 258 engaging, when the sleeve is in its normal (left) position, a groove 259 of a cam disc 260 (Fig. 9). The cam disc 260 is pinned toa shaft 26| (Figs. 'I and 8) rotating through one full revolution for each full cycle of a machine operation when .actuated by the shaft 2I4 through a train of

gears

262, 263, 264, 265, 266 (Figs. 2 and '1). But as mentioned before, the shaft 26|, due to its actuation by the main shaft 50 or rather by the shaft 2I4 connected to the latter, is also stopped when the main shaft is stopped and released respectively and thus any actuation of the cam disc 260 is controlled by the transaction key depressed and thus by the detent 240.

To the shaft 255 also an arm 261 (Figs. 1, 2 and 6) is secured to which a link 268 is pivoted. The link 268 is fixed at its other end to the printing table 210 arranged shiftably in the cross direction on rollers 21| (Fig. 7). A spring 212 holds normally the printing table 210 in its rest position (Figs. 1 and 2),. Thus the printing table 210 is moved whenever the shaft 255 and the arm 261 are rocked.

The rest or left hand end position of the sleeve 253 is maintained whenever the deposit key I I is depressed, since the detent is not moved during this machine operation. According to the configuration of the cam groove race of disc 260 (Fig. 9) the

arms

251 and 261 are not moved during the first partial operation, thus maintaining the printing table 210 in the initial position.

During the second partial operation, the printing table 210 first remains in its rest position but is then shifted by the first raise of the groove 259 of the cam disc 260 acting upon the roller 258 and thus actuating the

arms

251 and 261 by one step corresponding to the Width of a column towards the left, so that the print of the amount takes place in the second column provided for deposits in the ledger card (Fig. 14). Then the printing table is returned into its initial position by means of the cam disc 260.

During the third partial operation the same operative conditions prevail as in the second one, that is to say, after the date and consecutive number are printed by the impression hammer 206, the printing table 210 is shifted by one column towards the left, so that the print of the amount is effected, this time by the hammer 226 in the second amountcolumn of the third record material, the pass book. Thereafter the printing table is restored into the rest position.

When the withdrawal key I2 is depressed, the detent 240 is moved downwardly one step (Fig. 3) and the lever 25| shifts the sleeve 253 and the arm 251 one step towards the right (Figs. 1 and 8) to disengage the roller 258 from the groove 259 of the cam disc 260. In this position of the sleeve 253 neither the arm 251 nor the arm 261 is actuated and thus the printing table 210 is not moved at all during all the three partial operations.

In order to prevent in this position of sleeve 253 any movement of the table 210 by hand, a finger 215 rigidly arranged on the sleeve 253 contacts a fixed stop 216 (Figs. 1 and 8). All the amounts are therefore printed in the first amount column of the record materials (Figs. `14: and 15).

Upon depressing one of the balance keys I 3, the detent 240 is lowered two steps (Fig. 3) and the shaft 250 is rocked so far that the lever 25| shifts the sleeve 253 and its arm 251 by two steps into its right hand end position (Fig. '1) whereby another roller 213 of the arm 251 engages the periphery of a cam disc 214 pinned to the shaft 26| (Figs. l, 2, 1 and 10).

At the beginning of this operation, the

arms

251 and 261 are rocked counter-clockwise (Fig. 1) thus shifting the printing table by two steps, that is, by two columns towards the left. Owing to the configuration of the cam disc 214, the printing table is maintained in such a position during all three partial operations that the three strokes of the printing hammer 226 cause the print of the amount set up, in the right hand or balance column (Figs. 14 and 15).

The printing hammer 206 is not to be actuated during the registration of any balance, as this item is printed'on the same line as the previous deposit or withdrawal (Figs. 14 and 15) and, as said before, all the data such as date, consecutive number and ledger number have been already printed together with the amount of the deposit or withdrawal. For disabling the hammer 206 the printing table 210 is provided with a block 218 (Figs. 1, 2 and 6) which when the table has been moved by two steps engages the one arm of a crank lever 219 and rocks said lever in such a Way that its other arm locks the hammer 206. When the hammer driving lever 209 is actuated, the hammer 206 is prevented from following the lever 209 when released, so that no hammer stroke is initiated and no print is effected at all.

The transaction keys to I3 which determine the extent of shifting of the printing table are machine operation release keys as already mentioned and have to be released after each partial operation. 'Ihis is done by the rod |2| of the stopping and releasing mechanism after each partial operation. Restoration of the detent 240 into its rest position does not affect the adjustment of shaft 250 due to the slot and pin connection between link 241 and arm 248 (Fig. 3). In order to force, however, completion of any transaction started, the shaft 250 is latched in its initial adjustment during the whole machine operation by a locking segment 28| secured to the shaft 250 and provided with three notches (Fig. 2) each associated with one of the transaction keys II, I2 or |3. A locking pawl 282 plvoted on a stud 286 is adapted to enter one of said notches under the action of a roller 284 arranged on said pawl 282 which roller engages, by the pressure of a spring 283, the periphery of a cam discw285 pinned to the shaft 2 |4.

Upon depression of one of the transaction keys II, I2, I3, the shaft 250, the segment 26| and the

arms

251 and 261 are rocked counter-clockwise (Figs. 1 and 3) to an extent determined by the respective transaction key depressed, and the shaft 250 ls held adjusted during the whole cycle of machine operation by means of the locking pawl 282, engaging one of the notches of the segment 28| during all the three succeeding partial operations actuating it due to the configuration of the cam disc" 285.

Consecutive number device The consecutive number device is advanced by one step for each transaction performed. As entering a deposit or withdrawal and printing the balances are a part of a single transaction, the advancing movement of the consecutive number type wheels is suppressed in balance entering operations. The consecutive number type wheels 20| are advanced by a pawl 29| (Figs. 12 and 13), mounted on a yoke 292 actuated by a cam disc 294 by means of a lever 293. The cam disc 294 is connected, by means of

gears

295, 296, 291 with a shaft '298 rotatably and shiftably mounted in the machine frame. By means of a clutch 299-300, the shaft 298 is coupled with a driving shaft 30|, thus causing the advance movement of the consecutive number type wheels 20|. When the printing table 210 is shifted into the left hand end position, an' arm 302a of a yoke 302 secured to the table 210 contacts a collar 303 mounted on the shaft 298 and shifts the latter so far that the clutch 299--300 is disengaged, thus disconnecting the shaft 298 from the driving shaft 30|. Upon this movement, a stud 304 engages a notch 305 of a fixed wall 306 and the shaft 298 is locked against any rotation. During this shift the pinion 291 pinned to the shaft 298 remains in mesh with the wide pinion 296, although the driving member is separated from the driven member of the clutch and thus the consecutive number device is locked. When, after the print of the balance, the printing table 210 is restored into its rest position under the action of its spring 212, an arm 302D of the yoke 302 contacts the collar 303 and returns the shaft 298 into its initial position in which it is connected by the clutch 299-300 to its driving shaft 30|.

Line selection The printing table 210 is provided with a guiding frame 3| 0 (Figs. 1, 2 and 11) which is mounted shiftably thereon, in order to insert and set the record material to the line desired. Underneath the frame 3|0 a rail 3|| is fixed, provided with a series of holes 3|2 each corresponding to one of the lines. Below this rail 3| I, a bar 3|3 is fixed having mounted thereon a locking lever 3|4 which, under the action of a spring 3|8, engages, by its pointed stud 3|5, a bevelled groove 3|6 provided on the end of the shaft 2|4. This lever has also a pin 3|1 arranged to enter into a hole 3|2 of the rail 3| 'Ihe groove 3|6 of the shaft 2| 4 lies in the path of the stud 3|5 when the shaft 2|4 is in the home position (Fig. 11). Thereat, the stud 3|5 is positioned in the groove 3|6 and the lever 3|4 is lowered to such an extent that the pin 3|1 is disengaged from the holes 3|2 of the rail 3| I, thus allowing the guiding frame 3|0 to be moved by hand to select the desired line. Upon rotation of the shaft 2 I4 at the start of the machine operation the stud 3|5 leaves the groove 3|6. The lever 3|4 is raised thereby and the pin 3|1 enters the hole 3|2 representing the line selected. Therefore the printing table 210 is locked in the same line position until the shaft 2|4 has ended its full revolution, that is, after all the three partial operations are completed.

Operation To register a deposit, the transaction key I I is depressed. 'I'he detent 240 together with the sleeve 253 and the

arms

251 and 261 remain in their normal positions. The roller 258 of the arm 251 is kept in engagement with the cam groove 259 (Figs. 7 and 9) by which the printing table 210 is not moved during the rst partial operation, so that upon simultaneous actuation of both

hammers

206 and 226 on the receipt (Fig. 15)-which comprises only two amount columns--besides the date, consecutive number and ledger number, the amount and the symbol D are printed in the nrst amount column. After removal of the receipt the operator inserts the ledger card.

To release the second and the third partial operations, the same deposit key Il has to be depressed. When by inadvertence the operator tries to depress another transaction key I2 or I3, this is prevented by detent I5| associated with key II, which locks al1 the other keys, and also by shaft 250 which, at this time, is locked in the initial position by the pawl 282 engaging the iirst notch of segment 28|. 'Thus upon depressing the deposit key II the second time the second partial operation is initiated. At the beginning of the operation, the printing table 210 remains in its initial position until the impression hammer 206 has been actuated to print in the corresponding columns of the ledger card (Fig. 14) lthe date, the consecutive number and the ledger number. Then the printing table 21u is moved by one step towards the left by the cam disc 260 (Figs. 1, 7 and 9) and the printing hammer 226 is actuated. Thereby the amount is printed in the second amount column, the deposit column. Thereupon the table 210 is restored into its initial position.

During the third partial operation, the same working sequence is maintained, except that the imprint is made upon the pass book which has been inserted previously to depressing the key II the third time.

To register a withdrawal, the transaction key I2 is depressed, thus lowering the detent 240 by one step and rocking the shaft 250 through a certain angle counterclockwise (Fig. 3). The sleeve 253 as well as the

arms

251 and 261 are moved to the middle position (Fig. 8) in which neither the roller 258 nor the roller 213 engages its

cam disc

260 or 214 respectively. When the machine is released for operation, the printing table 210 remains stationary and as, in this case, the shaft 250 is locked in its second position during al1 three partial operations, the print of the amount set up takes place in the rst amount column, that is, the withdrawal column (Fig. 14) in each partial operation of this transaction. The release of the second and third partial operations can be accomplished by the Withdrawal key I2 only, because by the detent |52, pertinent to this key, all the others are locked, and by the pawl 282 engaging the second notch of segment 28|, shaft 250 is secured against any movement.

The new balance of an account, obtained from the old balance and a deposit or a withdrawal, is computed by the cashier and set up on the machine, as normally these types of machines have no add and subtract totalizer. The release of such an operation is obtained by the lower key I3, if the balance is positive, and by the upper key I3, if the balance is negative. In both cases, the detent 240 is lowered by two steps and the shaft 250 rotated through a corresponding angle. The sleeve 253 is moved thereby to its right hand end position in which the roller 213 engages the cam disc 214 (Fig. At the beginning of the operation the cam disc 214 shifts the printing table 210 two steps corresponding to the extent of two columns towards the left (Fig. 1). Thereby the block 218 disables by the lever 210 the printing hammer 206, whereas by the yoke 302 the clutch 299-300 is rendered ineffective to prevent any advance of the consecutive number type wheels Therefore, in each of the three partial operations of this transaction, only the hammer 226 is actuated to effect the imprint of the balance in the right hand amount column of each record material successively inserted. Towards the end of the third partial operation, the printing table 210 is restored into its initial position.

In the embodiment of the invention shown and described, the shifting of the printing table is effected automatically by the machine operation. It is of course also possible to obtain an automatic shifting movement of the printing table, during the machine operation from the Withdrawal position into the deposit position, while owing to a locking condition between the printing table 210 and the transaction keys I2 or I3. the printing table' would have to be positioned by hand, at the beginning of the operation, in the withdrawal column or in the balance column, before one of the transaction keys I2 or I3 may be depressed.
