Abstract: 614,346. Accounting-machines. NATIONAL CASH REGISTER CO. July 11, 1946, No. 20728. Convention date; June 3, 1943. [Class 106 (i)] A cash register or similar accounting-machine includes a number of coaxially-mounted totalizers, actuators therefor, means to shift the totalizers axially in relation to the actuators to align a selected totalizer therewith, engaging means for the totalizers, manipulative means adapted to select a particular totalizer for actuation, and means controlling the type of machine operation to be performed and adapted, in a certain position of adjustment, to shift the totalizers and control the engaging means to cause a different totalizer to be selected for actuation from that selected by the manipulative means. As described, there are two totalizers.. A number of depressible control keys, certain of which control the operation of an item totalizer when the machine is used as a cash register, are provided so that the various items comprised in each transaction may be entered, a sub-total printed, the amounts then added, and the total cleared therefrom printed and transferred to a group totalizer. If the transaction involves a single item, then the group totalizer is selected by a control key. For use as an adding machine, a control key is depressed to clear the item totalizer, which amount is automatically transferred to the group totalizer. The machine is conditioned for use either as a cash register or an adding machine according to the position of a control slide 72, Figs. 1 and 9, and is provided with an item totalizer 170 and a group totalizer 171, Fig. 22. The control slide has five positions of adjustment and is provided with a lock operated by two types of insertible keys : one key (reset key) permits the slide to be moved to reset total (i.e. total taking) position and the other key (read key) does not permit the slide to be moved beyond the read total (i.e. sub-total) position. The control slide 72 also controls the engaging and disengaging of the two totalizers with and from the actuators. The cash register involves the use of both totalizers. The item totalizer accumulates the items of a multiple item transaction before transferring the total thereof to the group totalizer. The control slide has a series of notches 279, Fig. 9, co-operating with a stud 280 in a spring-pulled arm 281 having a finger 283 adapted to cooperate with a shoulder on an arm 285 on the key-lock shaft 286 to obstruct clockwise releasing movement of the shaft when the slide 72 is moved from one position to another. With the slide in lock register position, a stud 287 thereon is positioned over a finger on the arm 285 to lock the shaft 286. A cam slot 289 on the slide moves an arm 290 to rock a shaft 258 to shift a detent when the slide is in all positions except register position. The slide also, through a cam 293 and locking bail 275, can lock the keys against depression when it is in all positions except register and adding positions. The mechanism of the machine is supported by two main frames 60, 61 on a base, the indicator and some of the printer mechanism being supported in auxiliary frames secured to the main frames, and a cabinet for the cash drawer supports the base. The keyboard comprises four rows of amount keys 80, and an additional row 81 when the machine is used as an adding machine; four rows of printing control keys 82 ; one row of transaction keys 83 to control the position of the printing wheels 421 and the engagement and disengagement and the selection of the totalizer; and a row of column selecting keys 84 which selectively control the shifting of the four lower order amount type wheels to cause printing in appropriate columns of the record web; a space key 85 ; and a drawer release key 86. The amount keys 80, Fig. 5, are supported in slots in plates 91, 92, retaining-rods 93 engage slots in the keys, and coil springs 101 extending horizontally of the keyboard resist depression of the keys. A detent 102 for each row of keys 80 locks them in depressed condition, and a control plate 103 releases the zero stop pawls so that the differential mechanism can be moved away from zero position and be arrested by the depressed amount keys. Depression of a key 80 releases a previously depressed key. The transaction keys 83 are similarly mounted, and any key, except the list key, may be released by depression of another transaction key. The column selection keys 84 are also similarly mounted, but can only be depressed when the control slide 72 is in register position. When a key 84 is not depressed, a zero stop mechanism causes the differential mechanism thereof to effect printing in a wide column on the left of the record web. The keyboard is readily removable. The amount differential mechanism is of known type and comprises a number of differential slides 104, Fig. 5, each having upward projections to co-operate with the keys, and movable actuators 123 controlled by the slides. The actuators are moved clockwise and counterclockwise by a segment 134 driven from a main shaft 79 which makes one complete clockwise revolution during a machine operation. Gear teeth 172 on the actuators are adapted to engage either of the two totalizers 170, 171. Totalizers. The item totalizer includes six wheels 170, Figs. 5 and 22, and the group totalizer also includes six wheels 171, arranged interspersed on a shiftable shaft 174 movable under the control of the slide 72 and transaction keys 83. The shaft 174 and an engaging shaft 177 are carried by a framework comprising plates 175, 176 having slots engaging studs in the frames 60, 61. The shaft 177 extends through the plates 175, 176 into slotted plates 184 engaging studs on the frames and having camming slots co-operating with rollers. An arm on the shaft 177 is pivoted to an actuating link 197, Fig. 14, by which the shaft is rotated to cause the selected totalizer to be engaged with the actuators 123. The link 197 has a slot into which projects a stud 386 on a cam lever 387 free on a stud 208. Rollers 388, 389 on the lever 387 co-operate, respectively, with plate cams 390, 391 secured on the main shaft 79. The link 197, which can be pivoted by the control slide 72 and transaction keys 83, carries a stud 198 co-operating with a link 199 connected to a shifting lever 202 which carries a stud 218 adapted to co-operate with control segments 219, 220. The lever 202 is pivoted to a lever 204 connected by a link 206 to a cam lever 207 rocked by plate cams 211, 212, Fig. 18, secured to the main shaft 79. Cash register operations. As a cash register for single cash items, depression of the transaction key results in the control segment 219, Fig. 14, positioning a surface 368, Fig. 18, of a control segment 363 below a stud 346 so that during the first clockwise movement of the lever 204 by the cams 211, 212 on the main shaft 79, a shifting lever 343 will operate idly and allow the group totalizer to remain opposite the stud 218 and control segment 220 will be below that stud, so that during return or counterclockwise movement of the lever 204 the movement of the stud is blocked, and the actuating link 197 of the totalizer is moved to the left to couple the link to a cam lever 387 to cause the group totalizer to be engaged with the actuators during their return stroke. This means that when the cash key is depressed the group totalizer remains in alignment with the actuators and will be engaged therewith to cause the amount set up on the keys to be entered therein. For single item charge transactions the amount is printed and set up on the indicators, but is not entered into the group totalizer. The key moves the control segment 219 to position the surface 368 on segment 363 below the stud 346, and a low portion on the segment will be below the stud 218. A projection 306 on an auxiliary control member 304, Figs. 9 and 14, will be opposite stud 218, but the member 304 can rock counterclockwise. When lever 204 is rocked clockwise and counterclockwise, the stud 218 will not be blocked in either direction and link 197 will not be coupled to the cam lever 387 to engage the totalizer with the actuators. Single item received on account transactions are accumulated in the group totalizer, but in no sale and paid out transactions no entry is made. In multiple item or list transactions the list key is depressed and will remain so during the entry of all items of the transaction until either the total cash list or total charge list key is depressed. The segment 219 is moved to position control segments 220 and 363, respectively, with a non-blocking portion in front of stud 218 and with a portion of the control surface 368 in front of stud 346. In this position an arm 348 is allowed to drop when the item totalizer is shifted to allow the latter to be retained in this position. The arm 348 positions a stud 378 thereon in front of an arm 377, Fig. 18, secured to a shaft 298 which is rotated by the movement of the control slide 72. The slide 72 is thus locked until either the total cash list or total charge list key is operated to clear the item totalizer, whereupon the arm 348 is restored to normal. On initial clockwise movement of lever 204, the lever 343 will be rocked on a stud 203 so that a stud 344 thereon will engage a member 336, Fig. 22, which rocks a shaft 331 to shift a slide 321 to position and lock the item totalizer opposite the actuators. The stud 218 is not blocked against movement during initial clockwise movement of lever 204 so that the link 197 is not moved, but on release of the lever 204 the stud is blocked and the item totalizer is engaged with the actuators 123. Sub-total of multiple item transactions is effected by depressing the sub-total key, whereby the sub-total of the amount standing in the item totalizer is removed and used to control the indicating and printing means and then returned to the item totalizer. Depression of the key adjusts
