Abstract: 24,014. National Cash Register Co. Nov. 28, 1904, [date applied for under Patents Act, 1901]. Receipts; checking and recording ; counting- apparatus. -A key-set crankoperated cash-register in which at any time a "summary "total" and a "grand total" may be printed, and in which the various items for the different sets of transactions may be printed in separate columns, is shown in elevation in Fig. 1. The operation of the amount keys 30 sets the registering-segments 50, Fig. 2, to differential positions, and, upon the subsequent operation of the crank 35, these segments are restored to normal position. During this restoration, the counter is actuated through the pinions 52, and the printing- wheels are set by the idle pinions 142, Figs. 8 and 12. For each of the five registering-segments 50, there is a series of three companion wheels on the shaft 53, the operating gear-wheel 52, the printer gear-wheel 140, and the counter gear-wheel 141. The shaft 144 carrying the idle pinions 142 is displaced laterally by the operation of a specialtransaction key 32, so that the printer wheel only is coupled up to the operating-wheel, and the counter is thrown out of operation. The amount keys, the clerk's keys, and the special-transaction keys are connected with type - wheels, and the mechanism which prints both upon a detail strip and a check is returned to normal position at the end of each operation. A summary total printer setting-key 33, a grand total printer setting-key 34, and corresponding operating-keys 320, 340 are provided. Operation of the summary total key connect up the summary total counter to the amount printing-wheels, so that when the counter is reset to zero, the printing-wheels are positioned ready for the impression to be taken when the operating- handle is actuated. Each counter can be reset to zero independently. When the grand-total keys are depressed; the grand total counter is thrown into mesh with the summary' total counter, as at each operation, and the summary total keys are also depressed. To print the special transactions in a column separate from the cash transactions, the detail strip is mounted upon a shifting printing-carriage 281, Fig. 5, and the operation of any one of the special keys serves to set a pin and groove mechanism so that, upon the operation of the handle, the carriage 281 is shifted laterally, if not in position, so as to effect the printing in the proper column. Upon the registration of these transactions, the indicator flash is retained in concealing position and remains so until the next cash transaction. This is effected by the shifting laterally of the shaft 43, bringing a cotter thereon into the path of a horizontal arm on the flashoperating arm 442. The registering segments 50 are locked normally in forward position and are released by key detents, and are prevented from overthrow movements by key detents. A restoring- frame 63, and its bar 64, is raised vertically on the operation of the crank, and lifts the indicator segments 54 into engagement with the block 59 formed on the segments 50. A forward movement of the frame 63, effected by cam mechanism, restores the segments 50 to normal zero position, and the segments 54 are moved forward an extent corresponding to the previous displacement of the segment 50 by the amount keys. The indicator is not returned to the zero position before each indication, since the pivotal point 81 is a shifting one, and the bar 82 is positioned with respect to the cams 97, 99. The detent plates, Fig. 4, co-operating with the amount keys comprise the unlatching- plate 100, and the stop plate 101. The latching- plate 100 serves also to unlock the registering- segments 50, by withdrawing the tooth 109 on the plate 100 from the teeth 51 on the segment 50. The pin 48 of the key first unlocks the segment 50 and then moves it to the proper distance. In the keyboard, the keys are releasable by a key of higher denomination, except that the nine key is released by the eight key. Upon the operation of the crank and the consequent rotation of the shaft 38, all the arms 113 are rocked upward to release all the latching-plates 100, the release of, the keys taking place immediately after the operation has begun. Tho clerk's and special transaction keys are provided with latching detent-plates, and their release is effected at the end of the machine operation. The detent plates for these two series of keys are given a differential movement by the keys to set the printing-wheels. The pinions 155 of the grand total counter are carried into mesh with the pinions 152 of the summary total counter by the rocking frame-157, and since this frame at each operation disconnects the counters, the summary total counter can be reset to zero independently of the other counter. A cam effects the rocking of the shaft 158 and the frame 157. Suitable transfer mechanism is provided for both the summary and grand total counters. Upon the depression of one of the special transaction keys 32, the shaft 144 carrying the idle pinions 142 is shifted to such an extent that the counters are thrown out. The printing-wheels controlled by the amount keys are set by the nested sleeves 151 connected to the printer gear-wheels 140. To aline the amount type-wheels 213, the gear-wheels 211 have fast upon them disks 237 which are formed with teeth engaged by a series of alineing pawls 238 attached to a frame mounted upon a shaft. To ink the type-wheels, there are ink - pad holders 301, Fig. 15, on the lever 300, and the inking of the consecutive numbering and dating wheels is effected by the pad 312 carried by the arm 313. To effect the printing of the summary total, the operating-key 320 is depressed, the summary total counter is reset to zero, and the machine operated; The printing-wheels are held locked normally by an arm engaging a pin on the restoring-link 247. The summary key effects the unlocking of the wheels, and is latched in its depressed position, until it is unlatched and permitted to return to normal position upon the operation of the machine, whereby the idle pinions 325 are thrown out of mesh with the printer actuating-gears 140 so that the restoring of the printer wheels to zero by a yoke frame will leave the counter reset to zero. When the grand total operating-key 340 is depressed, the shaft 158 is rocked and the counters brought into mesh. The counter is then reset to zero, so that when the machine is operated, the grand total is printed upon the check and detail strip. The shaft 154 is turned by a suitable key, and the summary total counter shaft is turned by the knurled disk 356. The machine is locked while the summary total counter is being reset to zero, by the engagement of a pawl and a notch in the disk 365. A pawl-lock provides that the summary total counter must be reset to zero before the grand total counter is reset to zero. Retaining pawls 402, 407 for the counter gear-wheels 141 and for the counter wheels of the grand total counter are provided. To print zeros on the higher-denomination wheels only when such are required, the wheels are each provided with two depressible zero pawls.
