Patent GB-926950-A (GB)
Abstract: 926,950. Cash registers; multiple-item operations. NATIONAL CASH REGISTER CO. March 14, 1962 [April 7, 1961], No. 9824/62. Class 106 (1). A cash register treats every item entry as part of a multiple-item entry and advances an item counter when any of a number of department keys is depressed to enter the item. Any of a number of clerk's keys have a double function. If such a key is depressed at the end of a multiple-item entry a total operation takes place, a customer counter is incremented by " one " and the item counter is conditioned to be reset by the next machine operation. If a clerk's key is depressed alone a no-scale operation takes place and a no-scale counter is incremented. Fig. 2 shows the arrangement of counters. Reset counter 64 is incremented each time a reset key is operated. Department counters 63 correspond to department keys and are incremented the first time a department key is depressed during a multiple-item operation. A tax counter 65 is incremented whenever a tax key is depressed to enter the tax into a main itemizer. The tax key also increments the item counter 66. The counters 67 correspond to clerk's keys and are incremented by depression of a clerk's key at the end of a multipleitem operation, when the total in the itemizer is printed, indicated and transferred to a group totalizer. At the same time a customer counter 70 is incremented. Tax item counter 68 records the number of taxable items entered into an auxiliary itemizer. No Sale counter 69 is incremented when a clerk's key is used alone. The number wheels of the counters are visible through the fascia of the register. A counter is selected by the rotation of shafts by known transaction differentials (one for each row of transaction keys) to bring counterbores on the shafts into register with operating levers of the selected counter. A typical department counter 63 has deep notch transfer mechanism and is operated by a tined pawl 95 carried by a yoke 96 which is maintained in either operated or restored position by a spring pawl 104. During a machine cycle rod 115 (Figs. 8, 14), is lowered releasing selecting lever 112 to sense for counterbore 132 in shaft 133. Full sensing movement is prevented unless operating lever 108 also senses counterbore 135 in shaft 136. The lever 108 in its clockwise sensing movement bears on stud 106 on yoke 96 and operates the counter. At a later stage in the machine cycle shaft 136 rocks clockwise returning levers 108, 112 to the position shown. The yoke 96 is held in operated position by pawl 104. If it is desired that the department counter be incremented each time the department key is depressed instead of, as preferred, only once in a multiple item operation, a stud 167 (Fig. 8), can be provided to engage projection 168 on yoke resetting arm 169 on the return movement of lever 108. The item counter 66 (Fig. 10), is similar to the department counter save that the operating lever 108 (Fig. 8), has two projections (Fig. 13, not shown), which engage the stud 106 on the counter yoke. One projection performs the function of projection 107, and the other resets the yoke as lever 108 is being reset. The item counter is reset in the first machine operation following the item total operation of a multiple item transaction. A cam 202 rocks segment 197 anti-clockwise to rotate shaft 196 shoulders on which are engaged by pawls 205 on the resetting wheels. Segment 197 remains in this position until the next final item total operation of the next multiple-item transaction. Operation of customer and no-sale counters by clerk's keys.-In the resetting item counter operation first described a roller at the end of lever 199 operates a pawl (Fig. 12, not shown), to rock a lever 292 (Fig. 14), so that a pin 291 locks customer counter selecting lever 264 against sensing the position of shaft 250. It is necessary to operate a department key to release lever 292. In fact, the registering movement of the yoke 96 (Fig. 8), is used to rock arm 169 and thereby (Fig. 12, not shown), lever 292. A second lever fast on shaft 293 with lever 292 is used to release the no-sale counter for selection over the period that the customer counter is blocked. When the customer counter 70 is selected by a clerk's key a pin 275 (Fig. 10), on the counter operating lever 263 returns the segment 197 from its operationed position to the position shown in Fig. 10 ready for resetting the item counter in the first machine operation (rotation of cam 202) after the multiple-item transaction just concluded. A reset key is provided whereby all the counters, save the reset counter which is incremented, are zeroized by motor action (Figs. 3 to 5, not shown).
