Abstract: 24,965. American Cash Register Manufacturing Co., and Wells, B. B Oct. 31. Locking-devices.-The check-issuing apparatus of a cash register is adapted to be made operative on actuation of any predetermined special transaction keys, or to be independently rendered operative or inoperative for any transaction, means also being provided for ensuring action of the printing-mechanism before the operation of the register can be completed, in the cases in which a check is issued. The check-strip passes between an advertisement-printing roller 7 and a dating and numbering roller 6, and their impression rollers, and thence past a knife 66 to item-printing wheels 5 operated in the usual way, the various rollers being driven by a one-way ratchet drive from a pinion driven by a segment fast with an operating-lever 73, the adding-mechanism being actuated by the restoration of a weighted lever 88 as usual in this type of machine by the closing of the drawer. The feed-rollers are normally held locked by a shouldered cam-groove 80, Fig. 8, in one of them engaging a stud 79 on a sliding plate 78, the cam-disk having also a notch 84 engaged so as to be locked by a lever 81 until the usual yoke 86 of the adding-mechanism falls far enough to bring the shoulder 91 of a cam 85 attached to it past the end of the lever. The cam 85 of the yoke also has a projection 109, Fig. 3, adapted to wipe over a pawl 108 of a plate 102 pivoted at 103, if the plate has been initially set for such engagement, the plate being thereby rocked so that an arm 104 thereon pushes the slide 78 over to free the locking-cam 80 and allow the check-issuing apparatus to be operated. The slide 78 has a recess 121 engaging a stud on an arm 118 fast on a shaft 117, which carries an arm 119 which on being so freed is rocked by a spring into the path of the yoke 86, thus preventing completion of the addition on the totalizer before the check has been printed and the slide 78 restored to initial position. The slight setting movement of the plate 102 is effected by a sliding plate 92, which can be lowered by one of a number of selective controlling-pins 97, Fig. 18, when it is engaged by a bevelled feather on the stem of a special transaction key, the key rocking the pin about its bearing in an aperture on a fixed plate 95 and so rocking the sliding plate 92. The selective controlling-pins 97 are set as desired by an authorized person for issuing a check for any predetermined transactions. Unset pins 97 are not engaged by the corresponding keys, which consequently do not rock the plate 102 to free the check-issuing apparatus. The plate 92 rocks the plate 102 through the medium of an interposed lever 100 with a turned-over shoulder 101. This lever 100 can be moved by an external handle into an ' off' position so as to be clear of the plate 102, thereby disabling the check-issuing apparatus for all transactions, or the lever 100 may be lowered so as to hold the plate 102 permanently set for action, thus causing a check issue on every operation, this being the on' position. These movements are given by mounting the pivot of the lever 100 eccentrically on a shaft 112 having an external handle set to the three positions for 'off,' 'normal,' and ' on' positions. In order to finish an operation of the machine with or without a check issue at will, even after the adding- mechanism has been locked in readiness for a check issue, an " optional " fitting is provided comprising a link 126, Fig. 10, with an external plunger, connected by a pin and slot to an arm on the adder locking-shaft 117 so that this can be released and the operation of the machine completed without issuing a check. When the handle on the shaft 112 is set to the 'off ' position, a pin 405 on the shaft draws forward a bar 400 which has a bent end 402 to pull the slide 78 positively into locking position for the check-issuing apparatus. At the end of every operation of the machine the drawer 90 finally engages a lever 500, which also thrusts the slide 78 into locking position.
