Patent GB-221812-A (GB)
Abstract: 221,812. Shipley, B. M. Sept. 12,1923, [Convention date]. Cash registers with operating-means.-In a machine of the " waiters " cash register type described in Specification 8119/15, having a grand-totalizer and an add-and-subtract totalizer the machine is released by depression of a key in any one of three banks namely two banks of keys denoting respectively odd and even multiples of five cents and a bank containing a five cents key and a release key.. Mechanism for releasing and controlling the various differential actuators to effect the necessary actuations of the totalizers under the control of these keys is also described. Keyboards.-There are three banks 25, Fig. 1, of waiter's keys, two banks of dollar keys, a bank 70 of keys denoting even multiples of 5 cents, an adjacent bank 69 for odd multiples of 5 cents, a bank containing a release key R, a " void " key and a 5 cents key, and a bank 96 of cashier's keys each adapted to be locked in normal and depressed positions by rotatable barrel locks 99. The 900 key 51 in the waiter's field of keys is used as an error-correcting key for cancelling a wrong setting of these keys. For this purpose the key is provided with a pin 52, Fig. 13, to depress a detent plate 54, having a foot to rock a yoke 60, the pin 58 of which is extended to overlie the tails of the zero trip pawls of all three banks. The rocking of these pawls effects the downward displacement of the usual detent plates and the release of the depressed keys. The waiter's keys are set at the beginning of an operation and normally remain set until released by the act of setting up another waiter's number. The two banks of double-figure cents keys are provided with the usual retaining detent plates 73, Fig. 9, and, as they serve also as release keys for the machine, with slotted plates 76 connected with the known release mechanism. The bank containing the release key proper, the " void key and the single 5 cents key is furnished with three slotted plates functioning as follows. One plate 82, Fig. 5, is moved only by the " void " key and when depressed latches with the notched end of a spring-controlled arm 87 loose on shaft 39. The plate is released at the end of the operation in the usual manner by the clockwise rocking of the shaft 39 which carries an arm 88 to depress a pin 89 on arm 87. Another plate 81, Fig. 11, is depressed only by the cents key for the purpose of removing the zero trip pawl 188 belonging to the odd cents bank 69 to enable the differential latch to move up and break on a fixed projection positioned at the point. The third of the three plates is moved by either the release key or the 5 cents key and operates similarly to the slotted plates 76 for effecting the release of the machine. Differential mechanism.-This is of the usual latch type but modified to meet the requirements of the particular arrangement of the lower amount keys described above. The differential mechanism for the even cents bank 70 is unaltered but that for the odd cents bank 69 is arranged so that its latch does not co-operate with any of the key-stems of this bank but, when allowed to travel along the bank, always breaks on the fixed projection previously referred to. Thus when, as previously stated, the 5 cents key is depressed to remove the zero trip pawl 188, Fig. 11, of the odd cents bank by means of a pin 185 and connections 186, 187, the differential mechanism of this bank moves to register 5. When, on the other hand, a key in the odd cents bank is depressed the slotted plate 76 of this bank releases the same zero trip pawl 188 to permit this registration of 5 cents and at the same time by means of a pin 194 connected with the zero trip pawl 189 of the even cents bank, this pawl also is disabled to allow the differential mechanism of this bank to register. The latch of this mechanism has a lateral extension projecting into the plane of the keys of the odd cents bank so that the latch breaks by contact with the key depressed in this bank. The Specification as open to inspection under Sect. 91 (3) (a) also contains the following. The cashier's keys 96 control, in the known manner, the corresponding indicating and printing elements and have each a lug to co-operate with a spring bolt 98, Fig. 12 (Cancelled), protruded by a cam groove in a rotatable barrel 99 provided with the usual tumblers 100. The keys 96 may thus be locked in their upper or lower positions by inserting the appropriate key in the barrel and rotating it to thrust the bolt 98 outwards. Known means are also described for printing the items and total upon a record-strip and an inserted slip. An item referring to a comestible returned is cancelled by printing a series of noughts over it and is re-printed together with the word " void " on the back of the slip. This subject-matter does not appear in the Specification as accepted.
