Abstract: 545,120. Cash registers. PERCIVAL, S. (Kooperativa Forbundet Forening U.P.A.). Sept. 13, 1939, No. 25719. [A Specification was laid open to inspection under Sect. 91 of the Acts, March 16, 1940.] [Class 106 (i)] A cash register or like calculating machine provided with at least two totalizers and differential members actuatable in dependence upon keys, is characterized in that the machine is provided with members, by means of which one totalizer (the subsidiary totalizer) may individually, i.e. independently of the other totalizer (the total totalizer), be put into such driving connection with the key set differential members of the machine that an accumulation of a series of various amounts is obtained, and that the said subsidiary totalizer, still keeping the sum of said amounts, may be brought out of said driving connection, and that the total totalizer may then be individually put into driving connection with the key set differential members in order to receive the accumulated sum of the subsidiary totalizer by manually entering it upon said setting members, a zeroizing device adapted to cooperate with the subsidiary totalizer and driven by the machine being arranged, after further manual control, to return the totalizer wheels of the last-mentioned totalizer to zero positions after the calculating operation has been completed. Single-item transactions.-With the parts in normal positions, the amount keys 3 are depressed and the main shaft 38 rotated by the handle to. set the differential setting members 1 and the transaction setting rack 26, and cam disc C is rocked downwards to bring the wheels of total totalizer T into mesh with coupling wheels 51 and toothed wheels 55 through the operation of members 12, 13, 49, 48, 50 and 18, as described in Specifications 509,441, 509,450 and 523,687. Multiple-item transactions.-For entering and printing multiple items, finger grip 72, Figs. 2 and 4, projecting through the side of the casing, is moved in the direction indicated. This causes hook 80 to catch at offset 81 on portion 149 fixed to the transaction setting rack 26 which is thereby arrested in its upward movement at the next working stroke to put coupling wheel 51 into mesh with the wheels of subsidiary totalizer H. Record strip.-Two coaxial feed rollers are provided, the one 84 being continually driven from the main shaft 38 via gearing, the other roller 84 being intermittently rotated by shaft 82 via arm 86 and hook 85. For single-item transactions, feeding takes place when press-roller 94 on angle lever 93, under the influence of a spring and a recess in cam disc 96, is pressed against feed roller 84 at each working stroke of the machine to feed a voucher of the usual length. When finger grip 72 is rocked for listing multiple items, cam disc 75, Figs. 3 and 4, rocks lever 99 which blocks angle lever 93 through pin 100. At the same time, cam disc 75 operates link 102 to rock lever 104 counter-clockwise and through rodmember 107 presses roller 109 (not shown) against intermittently rotated roller 83, so that the voucher receives a much shorter feed. Cutting off record-strip.-For single-item transactions, cam disc 112 rocks arm 114 to lift rod 117 and so operate cutting-off member 111. For multiple-item transactions, however, the cutting operation is prevented by the lateral displacement of rod 117 through members 75, 102, 121, 122, 124 (Fig. 6, not shown). Printing.-For single item transactions, all four platens 126, 127, 128, 129, Fig. 9, are operated through member 133 by cam disc 195. For listing multiple-items, however, disc 73 attached to pin 72 moves platens 127, 128, 129 into inoperative position through members 130, 132 (Fig. 8, not shown), so that only the items are printed. For single-item transactions and when the total is entered, a total-indicating marking 137 is turned into printing position by arm 138 operated by angle lever 18 as it brings totalizer T into operation. Zeroizing totalizers.-Subsidiary totalizer H is zeroized, after the multiple-item total has been entered and printed, by the clockwise turning of wheel 239, Fig. 2, controlled by lock 139. This moves rails 142, 146 in the directions indicated and projections 147 on rails 146 enter guide grooves 193 in the differential setting racks 1 and in transaction setting rack 26 to prevent accidental operation of the racks at the subsequent working stroke of the machine. Alternatively, rack 26 may be locked by the engagement of rail 142 with parts 81, 149. The movement of rail 142 rocks members 152, 153 to bring coupling wheel 159 on cradle 154, Fig. 12, into mesh with wheels 160 and 163 (also Figs. 13, 14, not shown), so. that at the working stroke of the machine, shaft 63 of totalizer H is rotated via wheels 169, 170, 171, 160, 159, 163, 167 and 166 to zeroize the totalizer. To zeroize the total totalizer T, lock 179 is operated to free lock 139 and wheel 239 for clockwise rotation, cradle 154 being rocked counter-clockwise and shaft 62 of totalizer T is rotated via wheels 169, 170, 171, 160, 158, 162, 164, 168 to zeroize the totalizer. To keep the zeroizing device locked except when zeroizing is to take place, cradle 154 has projections 173, 174, which to some extent enter recesses 175, 176 in discs 177, 178 united with toothed wheels 162, 163. Rocking the cradle 154 releases one of the discs while more securely locking the other. Member 151, Figs. 2 and 3, prevents depression of the starting key 180 except when the zeroizing mechanisms are in exact or neutral positions. Indicators.-When the machine is set for listing multiple-items the indicators 182 turned towards the customer are covered by a screen 183 raised by link 102 through members 184, 185. At the same time, rod 78, Fig. 2, rocks disc 188 to display a warning mark 198 to the operator. Operation.-The machine is ordinarily set for single item transactions. For multiple-item transactions, finger grip 72 is moved as shown in Fig. 4 to disable platens 127, 128, 129 and the cutting- off device. Screen 183 covers the customer's indicators and warning mark 198 is displayed to the operator. The amounts are now entered on keys 3 into totalizer H, being visible on the operator's indicators. The record strip is fed only a short distance each time. After all items have been entered, finger grip 72 is returned to original position, totalizer H being disengaged and totalizer T being brought into operation. The total on subsidiary totalizer H is now read off through window X, Fig. 2, and re-entered manually as 'for a single item transaction. Lock 139 and wheel 239 are now turned counterclockwise and totalizer H is zeroized by a machine operation, after which lock 139 and wheel 239 are returned to neutral position, when the machine is ready for the next operation.
