Patent GB-214991-A (GB)
Abstract: 214,991. Shipley, B. M. April 23, 1923, [Convention date]. Cash registers with operating-means and several item-value totalizers; printing totals and sub-totals.-In a machine provided with banks of totalizer-selecting keys and a total lever differentially-positioned for taking totals or subtotals from any one of the totalizer lines, means are provided (1) for permitting the clerks to use the total lever in conjunction with a " List " key in order to obtain the total of a series of items accumulated on the listing totalizer but preventing them from taking totals from any other totalizers (2) for enabling the manager to take totals from any except the transaction totalizers and (3) for allowing the proprietor to take a total from anv totalizer. The machine to which the invention is described as applied is of the type described in Specification 8119/15. The control banks are as shown in Fig. 11 and the machine is released for operation by depression of a key in the clerk's bank which bank includes a " Read " key 34 for use by the proprietor only, and a " List " key 35 for listing or for release purposes. The total lever may be moved freely from adding position to the " clerks " totaltaking position but its movement otherwise is prevented by plates 150, 151 normally lying across the slot to obstruct the lever but removable by manipulation of the manager's key insertible in locks 182. When the total lever 60 is displaced to a total-taking position, a link 153, Fig. 7, effects through gearing 155, 156, 158, 159, 161, the corresponding positioning of a rack 164 formed with recesses 170 co-operating with the depending legs 167 of the lower links supporting the detent plates of the control banks. If the total lever is placed in the " clerks " position, say for listing purposes, it is necessary to prevent depression of any of the clerks' keys and this is effected by the provision in connection with the rack 164 of a plate 171 supported by slots on studs 173. 175. When the rack is moved to the right by adjustment of the total lever to the " clerks position, the stud 172 on the rack, by bearing on a cam portion of its slot tilts the plate 171 clockwise so that it obstructs the leg 167<1> of the clerks' detent plate link. The detent plate does not co-operate with the " List " key so that this key is free to be depressed. When the manager wishes to obtain a total from a clerks' or department totalizer, he inserts his key in the lock 182 and turns it in order, through an eccentric, to slide the obstructing plate out of the path of the total lever. The turning of the key barrel also effects, through the sliding of plate 150, the rocking of a shaft 191 to operate a counter 192 and to cause the descent of a, plate 176 carrying the pin 175 which by means of the inclined slot 177 slides the plate 171 farther to the right and 'out of obstructing position. If the total lever is moved to the clerks' position therefore the manager is able to depress any of the clerks' keys and the removal of the obstructing plate 150 also permits him to take a total from a department totalizer. If, however, he places the total lever in its lowest or transaction position, the depression of the " List " key to release the machine for total-taking is not permitted. For this purpose the- " List " key co-operates with a lever 203 having a depending tail 202 normally free to pass between two blocks 206, 207 slidable on shaft 205 and kept apart by a spring 208. When the rack 164 is moved' to the extreme right by the placing of the total lever in the transaction position, a lug 212 slides the block 207 to the right and thus prevents movement of the lever 203 and therefore of the " List " key. In order that, under such conditions, the proprietor may take a total from the transaction totalizers he is provided with a special key to unlock the " Read " key 34. This key normally is locked by a spring bolt 219, Fig. 2, bearing against the key barrel 220, but by turning the barrel by his special key to present a slot to the bolt the proprietor can free the key 34 for depression to release the machine for operation.
