Abstract: 648,390. Accounting-machines. NATIONAL CASH REGISTER CO. July 28, 1947, No. 20285. Convention date, March 24, 1941. [Class, 106 (i)] [Also in Group XVI] An accounting machine comprises a plurality of differential mechanisms, certain of which are settable under the control of more than one row of control keys, a group of selecting devices settable by the differential mechanisms to control a linespacing mechanism for a record material, an additional selecting device set by an automatic stepping mechanism under the control of certain control keys to cause line-spacing only after a predetermined number of prints have been made, each in a different column, and a mechanism advanced with the automatic stepping mechanism and controlled by certain other control keys, in a machine operation initiated by depression of one of the latter keys, to restore the automatic stepping mechanism to an initial position. General. The invention is applied to a motor-operated machine of the Shipley type adapted for pay-roll transactions. The machine prints all items entered and totals taken on an audit strip and certain of these amounts, in known manner, on a combined cheque and statement for an employee and on a ledger card. A set of type wheels is provided for each column of the three record materials and the type wheels are positioned through ring gears by the differential mechanisms in known manner. Totalizers. The machine has a line of ten interspersed add totalizers, a line of five interspersed add totalizers and one balance totalizer and a line on which are mounted one add totalizer and one balance totalizer. Keyboard. The keyboard, Fig. 1, comprises seven rows of amount keys on which the number of hours worked by an employee and his clock number may be set up simultaneously on the four right-hand and three left-hand rows respectively or on which an amount may be set up, three rows of transaction keys and one row of total keys. Transaction differential mechanisms. The three transaction differential mechanisms are of the Shipley type and each is adapted to control one or both of the other differential mechanisms automatically in certain operations. Detents 205, 208, Figs. 3 and 4, mounted on a shaft 174 have arms 251, 247 which are connected by links 250, 240 to arms of a yoke 245 mounted on a shaft 246. When a key-locking shaft 61 is rocked at the beginning of a cycle, an arm 258 rocks a yoke 256 through a link 259 and a stud 255 in the yoke 256 is lowered beyond a shoulder on the arm 251 of the detent 205 to permit the latter and the connected parts to be rocked clockwise by a spring 252. When the " Clock Number-Hours Worked " key, in the fourth position of the first row, is depressed, a lug on the detent 205 engages a pin in the key-stem so that the detent moves through one step. Ah arm 248 secured to the yoke 245 is thus moved into the path of a block 233, Fig. 6, secured in a segment 231 integral with an arm 226 having a slot which embraces the pin 225 of the latch carried by the differential arm of the second transaction row, so that the latch is broken with this differential arm in its fifth position. If any key in the third row is depressed, the corresponding one of a series of lugs on the detent 208 engages a pin in the key-stem to permit two steps of movement of the detent so that the arm 248 enters the path of a block 234 on the segment 231 so as to break the latch of the second transaction differential mechanism in the sixth position. An arm 241 also secured to the yoke 245 is also moved into the path of a block 224, Fig. 5, mounted in a segment 221 integral with an arm 186 which has a slot embracing the latch-pin 187 of the first transaction differential mechanism so that the latch is broken in the fifth position. Finally, if the " Pick-up Earnings to Date '' key, in the third position of the second row, is depressed, a lug on the detent 208 engages a pin in the key-stem when the detent has moved three steps and the arm 241 has entered the path of a block 223 on the segment 221 so as to break the first transaction differential mechanism latch in the sixth position. When the " Gross Earnings " key, in the fourth position of the second row, is depressed, a pin 276 therein cams a link 277 downwardly so that a supporting arm 280 therefor rocks a zero stop 184 out of the path of the first differential arm which is then driven until it reaches its eigth position. A shoulder 293 on the segment 221 then engages a stud 291 in a lever 288 released into an operative position by a lever 284 engaged by a stud in the upper supporting arm of the link 277. The zero stop 184, Fig. 4, for the first transaction differential mechanism is held in an inoperative position by an arm of the detent 205 except when the latter is permitted its full movement into engagement with a stud 298. A detent 200, Fig. 6, connected by links 265, 272 and a yoke 267 to an arm 1270, is also released for clockwise movement by the downward movement of the stud 255 and lugs thereon co-operate with pins in the stems of the " Net Check " and " Earnings-to-date " keys so that if the former is depressed, the detent moves through one step while if the latter is depressed, it moves through two steps. A block secured to an arm 268 carried by the yoke 267 is thus moved into the path of a block 236 or 235 respectively, which blocks are mounted in a segment 232 integral with the arm 226, so as to break the latch of the second transaction differential mechanism in the second or zero position. If the corresponding detents are permitted full movements, the arms 268, 241 and 248 move to inoperative positions. Audit-strip frame. The audit-strip supply roll 355, Fig. 18, has trunnions which are held in V-shaped notches in blocks, mounted on a pair of plates 331, by a pair of latches 357, Fig. 17, against which the trunnions are formed by a spring 358 which engages the roll. The plates 331 are joined by a rod 333 and a plate 441 and, on a pin 340 in each plate 331, is pivoted 'an arm 341 having studs 343, 344, which embrace a slotted plate 342 secured to the machine base 56. By rocking a hand lever (not shown), a stud in the lever and a stud in an arm 395 fast on a shaft 387, to which the lever is secured, are raised to release a pair of latches 385 from engagement with studs 388 in the main machine frame. The audit-strip framework may then be slid forwardly until the front studs 344 strike a fixed rib 399, when the frame may be rocked about the pins 340 into a vertical position. A cover 345 pivoted on the rod 333 may then be rocked downwardly on release of a latch 349. The audit-strip is passed round rollers 363, 364, 367, 368 and 369 and round a pair of feed rollers 370 journalled on a shaft 372 out through a slot 380. It is pressed by a sprung lever 374 against the feed rollers. The rollers 364, 367 and 368 are mounted on a pair of plates 365 slidably supported by studs 381. Operation of an arm described below to shift these plates carries a stud in the arm into co-operation with a fixed plate so as to prevent withdrawal of the auditstrip frame during operation of the machine. Autographic arrangements. Autographic entries may be made on the strip through an aperture 346, Fig. 18, in the cover 345, and at the beginning of either a single cycle or the second of two cycles of an operation, an arm (not shown), which is fast on the shaft 372 and has a slot which embraces a stud in one of the plates 365, is rocked by cams so as to slide the plates 365 rearwardly to carry that part of the strip visible through the aperture 346 into the printing position. Printing driving mechanism. A gear 301, Fig. 7, on the main shaft 62 drives a first printing drive shaft 309, through gears 302, 306 and 308, once per revolution of the main shaft. A collar on the shaft 62 forms a bearing for an axially-aligned shaft 312 to which is secured a collar 314 having shoulders engaged by sprung pawls 313, 315 pivoted on a plate 310 secured to the shaft 62 so that the latter normally drives the shaft 312 and, through a gear 316 fast thereon and gears 317, 319, a second printing drive shaft 320. However, during the first cycle of a total-taking operation, an arm 321 is rocked by known means to engage a finger 322 of the pawl 313 so as to rock the latter to break the drive through the shaft 312 to the shaft 320 after only a partial rotation which is completed during the second cycle of the operation.. Audit-strip printing hammers. A hammer 483, Fig. 11, is provided for each of the five columns of the audit-strip, Fig. 36. During each operation of the machine, the hammers are partially raised by cams 487 on the second printing drive shaft 320 which initially rock a shaft 450, through a link 493 and an arm 494, in a counter-clockwise direction. Each of five arms 495 on the shaft 450 then engages a stud 498 in a corresponding lever 499 and rocks the lever, to which a corresponding hammer is connected by a link 500. Associated with each hammer is an arm 514, Fig. 12, on a shaft 465 which is rocked in a counter-clockwise direction by cams (not shown) on the shaft 320 and then restored during each machine operation. Connected to each arm 514 by a spring is an arm 511, which, if selected by the means described below, also rocks so as to lower, through a link 510, a link 503 until a notch therein engages a stud 501 in the associated lever 499. Cams 508 on the shaft 320 then shift the links 503 so that the lever 499 of the selected hammer is rocked further in a counter-clockwise direction to operate the selected hammer, such additional movement of the lever 499 being permitted by virtue of a space between the fingers of the arm 495 in which the stud 498 can move. Audit-strip column-spacing. Each of the arms 511, Fig. 12, associated with the printing hammers for the second, third and fourth columns carries a pivoted block of feelers which co-operate with control discs 565,
