Abstract: 449,004. Cash registers. BURROUGHS ADDING MACHINE CO., 6071, 2nd Boulevard, Detroit, Michigan, U.S.A. Sept. 14, 1934, No. 26394. Convention date, Sept. 15, 1933. [Class 106 (i)] A key-operated cash register is provided with a universal bail which is actuated by the depressed keys through non-sliding engagements and actuates all or most of the members and mechanisms which are operated without differential variations related to the values of the depressed keys. Keyboard and differential mechanism. The machine is provided with three banks of amount keys, " No Sale " and " Paid Out " keys, and a " preset " key 60 that is depressed. prior to each operation. Each amount and transaction key comprises a lever 9 pivoted on a shaft 5 and terminating at its upper end in a cam slot 11 adapted, upon depression of the key, differentially to position a bail 122, Fig. 4, for the associated bank. Each bail 122 is carried by arms 123 rockable about a shaft 84 and serves, through an arm 121 and yoke 120, to position indicator-tablet magazines 97 in the manner described in Specification 447,263 and, through an arm 157 depending from the yoke 120, to actuate a totalizer 155 in the manner described in Specification 449,005. Key - coupler. The coupler comprises a flanged plate 30 integral with arms 31 pivoted on a tubular bail 10. Both the coupler and bail extend across the full width of the machine, the bail being supported by two levers 12 rockable with the key shaft 5 and urged clockwise by a spring 14. The coupler, under the action of springs 34, tends to rock clockwise about the bail to engage its flange 32 over lugs 33 on the keys, but is normally restrained by the abutment with stops 37 of fingers 36 extending upwardly from the arms 31. However, upon the depression of a key or keys, the bail and coupler are rocked as a unit counterclockwise about the shaft 5, the fingers 36 disengage the studs 37 and the coupler rocks clockwise to coupling position. The coupler is more fully described in Specification 445,540. Full-stroke devices. To compel a full stroke of the depressed keys, the levers 12 carrying the bail 10 and key-coupler 30 are provided at their upper ends with teeth 16, Fig. 10, cooperating with full-stroke pawls 17. The pawls are pivoted on studs 18 and constantly urged towards an upright position by cam surfaces 23 on levers 21, the cam surfaces being pressed downwardly on to pins 24 on the pawls by springs 19. Selection of keys for depression. Upon the partial depression of a key to engage the fullstroke pawls 17 with the first tooth 16 of the levers 12, the bail 10 is rocked sufficiently to permit the key-coupler to move to coupling position with its flange 32 over the lug 33 of the partially depressed key. The machine is then said to be in " preset condition. Keys in other banks may now be partially depressed and coupled to the key first depressed. Upon the full depression of any one key, all the coupled keys are also fully depressed. " Preset " key. To facilitate the setting of the bail 10 and key-coupler 30 to "preset" position, a " preset " key 60 is provided, upon the depression of which the levers 12 are rocked through the desired angle by a lever 61, 63 pivoted to the key. Depression of the " preset " key also serves to release any keys that may have been incorrectly partiallydepressed. For this purpose, a lever 73 is provided that, upon depression of the " preset " key, rocks clockwise and by abutment with the finger 36 rocks the key-coupler counterclockwise to uncoupling position. In this position of the coupler, the ends 77 of its arms 31 abut fixed stops 78 to prevent overthrow of the levers 12 due to too rapid depression of the " preset " key. Upon release of the " preset " key the bail 10 is retained in " preset " condition by the full-stroke pawls and the coupler returns clockwise to couple the keys upon their subsequent partial depression. Locking undepressed keys. Upon the movement of the bail 10 and coupler 30 past the '' preset position, the undepressed keys are locked by the clockwise rocking of a plate 50, Fig. 4, about its pivot 51, whereby lugs 53 on the plate are positioned in the path of pins 52 on the keys. The plate is rocked by a pin on a crank 85, Fig. 3, actuated by the universal bail 10. Item-counters. Counters 170, 171, 172, Fig. 3, are provided to register the number of machine operations, " Paid Out " operations and " No Sale " operations, respectively. The counter 170 is actuated through arm 175, slide 174 and lever 176 by a bail 146 that is given a constant left-and-right excursion by the universal bail 10 at each machine operation to restore the tablet magazines and totalizer actuators. The counters 171 and 172 are similarly actuated by studs 183 on the " Paid Out " and " No Sale" key levers. Casing and cash drawer. The machine is provided with a casing of the kind described in Specification 447,264, a cash-drawer mounting of the kind described in Specification 444,246 and a cash-drawer latch mechanism of the kind described in Specification 444,247, [Group XXV]. Reference has been directed by the Comptroller to Specifications 18052/93, 2981/94, and 25241/97, [all in Class 106].
