Abstract: 547,954. Cash registers. NATIONAL CASH REGISTER CO. March 17, 1941, No. 3647. Convention date, March 18, 1940. [Class 106 (i)] A plurality of selectively operable members are connected to the record feeding means so as to cause the record material automatically to be fed to the line corresponding to the member operated. The machine is to be used by telephone &c. companies for preparing statement slips comprising a customer's bill and a plurality of detachable stubs. The machine is of the type described in Specification 447,481. Any line may be selected in the first operation and the remaining lines in any order, but entries must be made in the first line during the first operation. As shown, normally the machine prints a six line bill, but if a five line bill is required, the second item is omitted and all succeeding items are moved up one line. The machine is key-set and independently operated by motor but may be operated by hand. Key-board. The machine has seven rows of amount keys 52, four rows of printing keys 53 and a combination row 54 which may be used with keys 53 or 52. The machine has the usual Shipley control plate 64 controlled by keys 55 to 60 and three lines of totalizers. Differential mechanism. The machine is of the well-known type in which the actuator 71 is normally latched to a constant excursion driving segment 83 operated through members 85, 84 from double cams 89, 90 and a main shaft 51, the latch 79 being broken by the stem of a depressed key and the actuator held by a part of the latch engaging one of a set of fixed notches 93. At the completion of outward movement of the driving segment, a roller 96 on the member 85 moves the beam 98 to engage the hub of the actuator and thus through slot and roller 101, 102 and rod 103 to position indicator and totalizer selecting segments 104 and also segments 107 to position the printing mechanism. Zero-elimination mechanism. The cents and dimes banks have zeros printed at all times but all other banks have zero-elimination. Near the beginning of the revolution of the main shaft 51, the shaft 133 is rocked clockwise. This through arm 134 and the stud 135 rocks the arm of the next lower bank and so on The arm 151 through roller 125 also shifts slide 116 to disengage its notch from pin 115 in the zeroelimination cam 110. When a key 52 is depressed. the segment 107 prevents return of slide 116 with return of shaft 133. If no key is depressed, the slide can return. After this the shaft 117 is rocked by cam and link mechanism from shaft 51 and the segment 110 is rocked so that through its cam slot, the segment 112 is rocked to one position beyond zero which is blank and the zero is not printed. The printing keys 53, 54 have their similar zero-elimination mechanism. When any one of the total keys 56, 57, 58 is depressed, the control plate described in the Specifications referred to causes the bank 54 to be connected to the highest order of the bank 52 for zero elimination in the lower denominations. Keys 55, 59 and 60 break this connection. Transaction keys. Depression of a key 62 positions sectors through a latch differential mechanism similar to that described above and the selected totalizers are placed in alignment with actuators 71. Another segment similar to the segment 107 positions printing and indicating mechanism. The same applies to bank 63. The external teeth of gear 236 drive a second transaction bank type wheel 241 for one column and the shaft 239 by pinions and ring gear drive type wheels for the other columns and an indicator gear 240 is visible in an opening in the casing. Statement slip feeding mechanism. The slip is presented to the throat between a guide 245 and table 243 and under type wheels 186 to feed and pressure rollers 247, 248 up to a stop 250. The roller 247 and stop 250 are fast on the shaft 251 and the flat on the roller is uppermost when the machine is at rest. After printing, the roller 247 feeds the slip through the opening 261, the guide 245 being now reversed, to ejecting rollers 263, 264. A gear 267 on the shaft 251 meshes with a rack 268 guided by slots and rollers 269 on studs 270, 271. The rack has a stud 272 pivotally supporting a lever 273 provided with rollers 274, 275 adapted to co-operate with camming slots 276, 277 in a rack 278 and a " first line " control slide 279 respectively guided by slots on rollers 269. The rack 278 meshes with a pinion 280 on a shaft 281 carrying a segment gear 282 meshing with a gear 283 on the control shaft 284 for the second transaction bank. This is connected through gears 285, 286 with a sector 290 free on shaft 113 having camming slots 291, 292 co-operating with studs 293, 294 on a shifting plate 295 slotted to straddle shaft 113. The studs extend at one end into parallel driving slots 296, 297 in a plate 298 fixed to shaft 113. The other ends of the studs bear by rollers 299, 300 on a cam 301 free on shaft 113 and having a gear 302 meshing with a sector 303 connected by a link 305 with the shifting lever 306. A stud 309 on a detent 310 engages one of two notches in a cross slot 308 to locate the lever. A pawl prevents release of key lock shaft 50 while the lever 306 is being changed from a six-line position to a five-line position. Movement to the five-line position causes rack 278 to advance one line space. Operation of first-line control slide. This slide, 279 is pulled to the right, Fig. 16, by a spring 322 and carries a square stud 323 adapted to engage a shoulder 324 on a driving slide 325 moved by the lever 327 and cam 330 on the shaft 332. This shaft is connected by gears 333, 334, 336 to a shaft 320 in alignment with the main shaft 51 to which it is connected by a clutch not shown. In addition and subtraction, the shaft 51 makes one revolution clockwise, and in total and sub-total operations two revolutions. The shaft 332 is connected to the shaft 51 and makes one revolution during adding. In total and subtotal operations, the shaft 320 is clutched in for the second cycle only. Clockwise movement of shaft 332 moves the slide 325 forwardly and through shoulder 324 and stud 323 moves slide 279 which via slot 277 and roller 275 moves rack 268 to feed the slip rearwardly. The shoulder 337 on slide 279 moves past a spring pawl 338 and overfeeds the slip beyond the opening 261. Next, the springs 322, 331 return slides 279, 325 and the rack until the pawl 338 arrests the slide 279 and rack with the first line of the slip at printing position, the slide 325 continuing home. The slide 279 pivotally carries at 343 a spring pawl 344, Fig. 17, a roller on which is adapted to engage a flat 347 on a lever 348 pivoting on stud 270. A roller 349 on the lever 348 engages a cam 350 on the second transaction shaft 284. A tooth 351 on pawl 344 may engage a shoulder 352 on a booster slide 353 worked by a lever 355 from a cam 358 on shaft 332. Depression of a local-service key 62 or 63 causes the second transaction differential to position the cam 350 so that a high portion is opposite the roller 349 in home position. A flat on pawl 344 engages an undercut surface on slide 353 and the roller 346 is at this time out of the path of the surface 347 of lever 348. Positioning of slide 279 then causes roller 346 to ride on to surface 347 depressing the pawl to move the tooth 351 out of the path of the shoulder 352 and forward movement of slide 353 will not be imparted to slide 279. Line-selecting by second transaction bank. Depressing the " additional messages" key 63 selects the second line of the slip by positioning the cam 350 to bring the low portion opposite stud 349. The tooth 351 moves into path of shoulder 352 prior to forward movement of the booster slide 353 ; the engagement of pawl 344 with the shoulder 352 is limited by the stud 321 in conjunction with an extension of slide 279. The rotation of cam 358 moves slide 353 forward and by pawl and shoulder 352, 344 the slide 279. During this movement, the camming action of slots 276, 277 in co-operation with rollers 274, 275 on lever 273 disengages the roller 275 from slot 277 and engages roller 274 with slot 276 in rack 278. This shifts control of feeding from the rack 268 to the rack 278 which is positioned by the " additional messages key" 63. The slide 279 returns with slide 353 until a shoulder 362 engages the retaining pawl 338 where it remains until ejection. A surface 363 on slide 279 in co-operation with the roller 275 retains roller 274 in engagement with slot 276 when the slide is held by pawl 338 and a similar surface 364 on the rack 278 in co-operation with roller 274 retains the roller 275 in engagement with the slot 277. Slip-ejecting mechanism. An extension of the control lever 348 has a camming surface 373 adapted to co-operate with a stud 374 on a lever 375 free on shaft 281. A crank 378 fast on shaft 281 has a surface 377 held by spring 379 against the stud 376 on lever 375. The lever 375 is connected by a hub 382 to an arm 383 free on shaft 281 and having a surface 381 held by a spring 340 against a stud on pawl 338. A downward extension of arm 383 pivotally supports selecting disc feelers 384, 385 of which there are two feelers 384 feeling control discs 386 and 387 and one feeler 385 feeling disc 387. The disc 386 is connected by gear and link to the control plate while the disc 387 is geared up to a sector positioned by the differential mechanism for the first transaction bank. According to the position of the discs 386 and 387 by the keys therefore the feed of the slip is controlled by positioning of the various slides so that the slip is ejected or not ejected according to which keys are depressed.
