Abstract: 215,749. Shipley, B. M. May 7, 1923, [Convention date]. Cash registers with item-printing mechanism; voucher-issuing; printing on bills.-In a machine provided with means for printing the item on a voucher and an inserted slip, the printing and issue of a voucher are controlled by a setting-knob, by a special key, by the "list" key, by the transaction &c. banks of keys, by the total lever and by the presence or absence of a slip. Voucher, feeding, perforating. printing and severing. The mechanism for effecting these operations under the control of setting-knobs is of known kind, the knobs being manipulated to produce a single voucher or a stub voucher or no voucher at all and the controls being effected through the medium of pin-carrying discs 31, 64, and cams 85 slidable axially to be operative or inoperative to drive geneva mechanism actuating the voucher-feed, severing, perforating and impression mechanisms. The sliding movements of the discs are derived from the main shaft 25 through a pitman 155 supported by a link 156 and pivotally carrying two bell-crank levers 153, 154 arranged side by side and each capable of being effective to seize a pin 151 on a shaft 90 and slide it lengthwise to shift the discs forward out of operative position. If both bell-crank levers are prevented from rising when they move with the pitman 155, the various mechanisms concerned in the voucher-issuing will be active but if either is allowed to rise, that is, to swing counterclockwise, its recess 152 will seize the pin 151 and, in the return movement of the pitman, will slide the discs forward to disable the drives and prevent a voucher-issue. Voucher-issue, control by special key. To issue a voucher a key 180, Fig. 1, may be depressed so as to slide a link 206 downwardly to bring its lower bent end against the extended upper edge of the lever 154. Provided lever 153 is also prevented from rising, this depression of key 180 will therefore ensure the issue of a voucher. A detent pawl 183 and a locking slide 185, both controlled by the main shaft, are provided to hold and lock the key during the operation of the machine. Voucher-issue, control by setting-knob 209. By turning this knob to the " on " position, an arm 218, Fig. 7, engaging a pin 219 swings a lever 220 counterclockwise to bring its bent end 222 against the lever 154 and thus prevent the latter from disabling the voucher-issuing mechanism. Voucher-issue, control by the machine control keys. There are three banks of these keys and each bank differentially controls the positions of racks 244, Figs. 7 and 8, furnished with recessed edges 245 co-operating with the bent end 247 of the lever 220 referred to in the preceding paragraph. Unless all three racks present a recess to the end 247, therefore, the lever 220 is constrained to maintain the position shown in Fig. 7 to allow a voucher to be issued. Voucher-issue, control by the " list " key. In order that the issue of a voucher shall not occur when " listing " is performed, the rack 244 of the bank containing the list key is provided with a pin 255, Fig. 8, adapted in the zero position and the first or list position of the rack to underlie an arm 257 fast on a shaft 221 carrying another arm 258 engaging by a pin 259 a spring- controlled lever 252. This location of pin 255 prevents clockwise rotation of the lever under the pull of its spring 254 and, therefore, the arm 253 of the lever does not obstruct the lever 153 which may therefore rise and disable the voucher-issuing mechanism. Movement of the rack to any other position liberates arm 257 and consequently lever 252 which is then turned to bring its arm 253 above lever 153. Voucher-issue, control by presence or absence of a slip. When a slip is present in the machine, the voucher-issuing mechanism is disabled. For this purpose the known slip-feeling arm 263, Fig. 5, and its controlling pitman 265 are in pin-andslot connection at 271 with a shaft 217 having an arm 274 carrying a pin 275 engaging an arm 260 of the lever 252. When no slip is present, the feeling-arm rises through the table and consequently arm 274 can rock counterclockwise and lever 252 is free to take up its position above lever 153 to permit the voucher-issue. If a slip is present the lever 252 is held in the position shown in Fig. 5 and the lever 153 is at liberty to rise and disable the issuing-mechanism. Voucher-issue, control by the total-taking mechanism. The movement of the total-taking lever out of adding-position to any one of its total-taking positions, causes in a known manner, a clockwise rotation of shaft 325, Figs. 1 and 7, to remove a pin 333 from obstructive engagement with a pivoted arm 330. The lower branch of this arm can thus no longer hold lever 252 which is therefore free to rotate from above lever 153 so that this may rise and disable the voucher-issuing mechanism. Slip-feeling mechanism. As stated above, the slip is felt by the arm 263, Fig. 5, connected to the pitman 265 controlled by a spring 267 and a cam 268. When a slip is present it prevents the arm from rising very far and consequently a pin 280, Fig. 6, carried by a spring-controlled slide 279 mounted on a lever 266 pivoted to the pitman 265, is not moved outside the path of a one-way pawl 281 pivoted on an arm 282 rocked from the main printer shaft 24. When this arm is rocked immediately after the feeling-operation, the pawl engages the pin 280 and restores the arm 263 and pitman 265 to normal position wherein they are held until the arm 282 and pawl 281 are rocked back again. If no slip is present, the arm 263 rises fully and therefore the pin 280 is carried up beyond the orbit of pawl 281 which therefore subsequently descends without effect. The Specification as open to inspection under Sect 91 (3) (a) also describes means for controlling the slip-printing mechanism in accordance with the keyboard setting and the total-lever position as well as by the presence or absence of a slip. This forms the subject-matter of Specification 224,535 and does not appear in the present Specification as accepted.
