Abstract: 605,591. Cash registers. NATIONAL CASH REGISTER CO. Dec. 21, 1945, No. 34788. Convention date, Jan. 22, 1943. [Class 106 (i)] A cash register or similar accounting machine includes a plurality of storage devices selectable for the accumulation of totals therein under control of manually operable means, individual means associated with each storage device and adapted to indicate which storage devices have been selected for receiving an entry, and means controlled by said indicating means automatically to select a related operated storage device for a total taking operation, if it has been previously selected to receive an entry. The embodiment is described as applied to a machine of the type described in Specification 537,503 and is for use in a bank, where the most active accounts are registered on the storage devices, which are arranged in a Shipley type of machine in the place of the usual indicators and the No. 1 totalizer line. A pin-board indicates which accounts have been active and which of those have been overdrawn since the last resetting of the storage devices and pin-board. The storage devices may be selected for resetting individually or automatically. Totalizers. General. The machine has the usual totalizers on Nos. 2 and 3 lines, selected for engagement with the actuators 63 by the respective rows of transaction keys 86, 89 to register the amounts set up on the amount keys 58, Figs. 1, 2. A balance totalizer occupies the No. 1 position, the adding or subtracting wheels of which are selected for engagement with the actuators 63 by a Deposit key 87 or Withdrawal key 88, respectively. All types of operations are initiated by depressing the start bar 91. The machine performs one cycle in adding or subtracting operations and two cycles in total or sub-total taking, under the control of the usual total control lever 92. The printing mechanism is of.known type. Balance totalizer. All computations of amounts stored in the various storage devices are performed in the balance totalizer. In entering positive or negative amounts, the selected set of storage wheels is first reversely rotated to zero to transfer the amount stored thereon to the plus side of the previously zeroized balance totalizer through a set of auxiliary actuators. The balance totalizer is then disengaged from the auxiliary actuators and engaged with the main actuators, and the amount set up on the keyboard is added or subtracted according to whether the Deposit or Withdrawal key has been depressed. The balance totalizer is disengaged from the main actuators and re-engaged. with the auxiliary actuators. At the beginning of the next operation, the auxiliary actuators are rotated to transfer the amount on the balance totalizer to the storage wheels. As described, the balance totalizer comprises nine denominational units, each comprising a plus wheel 166 (Figs. 2, 3) and a minus wheel 167 (not shown), free on a shaft carried by a framework 169 and secured to gears meshing with pinions 172, 173, Fig. 10, meshing with each other, these pinions being mounted on a plate 174 having an extension engaging a slot in a U-shaped. bracket 175. The plus wheel 166 is integral with a zero stop disc 176, Fig. 17, and a gear 177 which meshes with an intermediate gear 178 meshing with a long pinion 180. The frame 169 is positioned laterally by known differential mechanism controlled by the keys 87, 88 to align the add or subtract wheels 166 or 167 with the amount actuators 63. Engaging mechanism for the balance totalizer. When key 87 or 88 is depressed, a disc 221, Fig. 7, is positioned to act as a fulcrum for an arm 215 so that when a crank 217 is rocked counterclockwise in known manner, the arm 215 rocks clockwise to shift a link 208 upwards to engage a stud 209 with the hook of an engaging spider 213, which is rocked clockwise, after the actuators 63 have been positioned under the influence of the amount keys, to carry the stud 209 with it and to shift the link 208 downwards to rock arms 203, 200 and a shaft 189 counterclockwise, and through the action of rollers 201 in slots 202 to shift the framework 169 downwards. This disengages the gear 178, 17 from the long pinion 180 and engages the selected plus wheels 166 or minus wheels of the balance totalizer with the corresponding actuators 63, return movement of which enters the amount set up on the keyboard into the selected side of the balance totalizer. The engaging spider 213 then returns counterclockwise to lift the frame 169 to disengage the balance totalizer from the actuators 63 and to re-engage the intermediate gears 178 with the long pinions 180. If neither key 87 nor 88 is depressed, a low portion of the disc 221 is opposite the stud 220 and the stud 209 remains in the locking portion of an L-shaped slot 210 to prevent machine operation. In add and subtract operations, the stud 220 moves freely also in a camming slot 222, Fig. 7, in a plate 223 integral with the total control lever 92, but when the lever 92 is moved to No. 1 read or No. 1 reset position, the slot 222 acts on the stud 220 to rock the arm 215 clockwise to engage the stud 209 with a hook 212, whereupon the engaging spider causes the balance totalizer to be engaged and disengaged in the second cycle of a total-taking operation in the usual manner. Carry-over mechanism. In passing through zero, a long tooth on the wheel 166 or 167, as the case may be, rocks a pawl 224, Fig. 20, counterclockwise to trip the carry-over mechanism for the next higher denomination. Fugitive one mechanism. When the highest order plus wheel 166 of the balance totalizer passes through zero while being rotated subtractively, a finger 241 on said wheel, Fig. 18, rocks a disc 242, shaft 243 and cam 244, Fig. 20, clockwise to rock a tripping arm 245, adjacent the lowest order, counterclockwise against spring action, and as the frame 169 is in its downward position at this time, the arm 245 rocks a lever 247 clockwise to rock a finger 250, shaft 251 and arm 252 to release a transfer control arm 254. This arm rocks clockwise under spring action to release the usual transfer segment 256 which rotates the subtract wheel 167 of the lowest order one step to enter the fugitive one. When the balance changes from negative to positive in an additive operation, the finger 241 causes the entry of the fugitive one into the add wheel 166 in a similar manner. Aligner mechanism for balance totalizer. When the balance totalizer wheels are not operatively connected to the actuators 63 or pinions 180, they are engaged by aligners 262, Fig. 17, controlled by a cam 261, Fig. 7, which rocks a crank 260 and shaft 179 when the framework 169 moves up or down. Zero stop mechanism for the balance totalizer. When the balance totalizer is zeroized to transfer the amount into the selected storage device, it is disconnected from the main actuators, and therefore auxiliary zero stop mechanism is provided. Zero stop pawls 263, Fig. 17, are spring-pressed counterclockwise to lie in the path of stop teeth 176 secured to the wheels 166. When the frame 169 is lowered to engage the wheels 166 with the main actuations, extensions 265 of the pawls 263 engage a shaft 266 to rock the pawls 263 into ineffective, position. Storage devices. Selecting mechanism, general. As described, there are one hundred storage devices, arranged in ten sets of wheels 268, Fig. 2, supported in a circle about a shaft 270, and each line of wheels comprising ten storage devices arranged in nine denominational groups of wheels. The auxiliary actuators 269 are revolved and shifted laterally by the shaft 270, to which they are connected by friction clutches, and the actuators 269 mesh with the long pinions 180 for the appropriate denominations. The actuators 269 are shifted laterally under the control of the keys 271 to select the appropriate set of storage wheels 268 spaced across the register. A rod 267 carrying the selected line of wheels 268 is then shifted inwardly under the control of keys 272 to engage the appropriate wheels with the auxiliary actuators 269. Lateral selection of storage device. The keys 271, Figs. 1, 36, control a ledger type differential mechanism to position a segment 348 and via link 351 and segment 352, Fig. 3 (and Figs. 14, 16, not shown) positions a sleeve - 358, held against axial displacement. Rollers mounted in the sleeve 358 co-operate with helical camming grooves 363, 364 to shift a drum cam 365 and therefore the shaft 270 and auxiliary actuators 269 axially into alignment with the denominational set of storage wheels 268 corresponding to the depressed key 271. Radial selection mechanism. The keys 272 control similar differential mechanism, Fig. 23, to position a shaft 326 and, via linkage (Fig. 4, not, shown), a storage line selecting disc 379, Fig. 13, secured to an aligning disc 382, Fig. 17, arms 384, 386 (also Fig. 5) and an aligning disc 388. Levers- 390, 391, pivoted to arms 384, 386, carry studs 392, 393 co-operating with camming slots 394, 395 in a storage line engaging disc 396, Fig. 5, secured to a further disc 398, Fig. 13, a torsion spring forming a yieldable connection between the discs 379, 398. The levers 390, 391 carry studs 403, 404, Figs. 5, 17, and when the discs 379, 382, 388, 396 are rotated by the differential mechanism slots in the studs 403, 303 engage studs 405, 406 in a pair of arms 407, 408 corresponding to the selected line of storage wheels, the arms 407, 408 being mounted for radial sliding movement in fixed plates so as to move the corresponding storage device shaft 267. Zero stop and aligner mechanism for storage devices. Each storage device wheel 268 has a long tooth always in the path of a zero stop bar 419, Fig. 17, this being possible since the wheels never pass through zero, carry-over taking place only when the amount has been transferred to the balance totalizer. The storage wheels are held in set position when disengaged
