Abstract: 447,263. Cash registers. BURROUGHS ADDING MACHINE CO., 6071, 2nd Boulevard, Detroit, Michigan, U.S.A. Sept. 14, 1934, No. 26396. Convention date, Sept. 15, 1933. [Class 106 (i)] Tablet indicators.-The displayed indicator tablets of a key-operated cash register are restored into magazines upon the down-stroke of a key or keys, the up-stroke serving, first to position the magazines in accordance with the key or keys depressed and then to withdraw the tablet or tablets thus selected to visible position. The invention is described as applied to the key set and operated cash register forming the subject-matter of Specifications 445,540 and 449,004, wherein the key levers 4, Figs. 3 and 5, are coupled, after partial depression to " preset " position, by a key coupler 30 pivoted on a universal bail 10 that is engaged by the keys and rockable with its supporting levers 12 about the axis of the key shaft 5. The tablet indicators 96 are stored in magazines 97 formed of synthetic resin or other light material and are raised in pairs, one on each side of the machine, by hooks 94 depending from a pair of bails 93 extending across the full width of the machine. The zero tablets 96‹ and cash tablets are permanently in position, other selected tablets being raised in front of them. The bails are raised with selected tablets at the end of an operation and lowered to restore the tablets to their magazines at the beginning of a succeeding operation. A pair of magazines is provided for each denomination of the amount and for the characterizing tablets, the pairs being supported by arms 110 rockable about a shaft 84 and so connected by yokes 111 as to enable the figures of the amount to appear in correct order at each side of the machine. The tablets are selected by the differential positioning of the pairs of magazines by the keys prior to the elevation of the bails 93. Tablets, raising and lowering. The tablet raising and lowering bails 93 are rigidly connected by arms 89 to guide forks 92 that extend downwardly and embrace the shafts of pinions 87, studs 95 projecting from these guides extending into upwardly directed guide forks 921 secured to the frame. The bails, thus guided, are connected for operation by links 91 to arms 88 rigid with pinions 87. Toothed sectors 86 on the upwardly extending arms of levers 56 mesh with the pinions 87, and are actuated by studs 81 that project from the universal bail levers 12 into cam slots 82 formed in the horizontal arms of the levers 56. The cam slots are so shaped that the first step of movement of the bail 10 to " preset " position, lowers the indicator bails 93 to the position shown in Fig. 4, wherein the coloured surfaces of the bails indicate that an operation has been begun but not completed. Immediately upon the movement of the universal bail from " preset " position, the tablets are completely lowered into their magazines which are thus freed to receive their new setting unobstructed by the hooks 94 which are positioned in the path of slots in the upper ends of the tablets. At the end of the operation, the return of the bail 10 raises the indicator bails to elevate the selected tablets to indicating position. Tablets, selecting. The yoke 111 connecting each pair of tablet magazines is provided with an arm 113, Figs. 3 and 5, that in the zero position of the magazines rests by its foot 114 on a cross-shaft 2 of the machine. A toothed sector 115 extends upwardly from the arm 113 and is engageable differentially by a pin 116 projecting from a link 117 pivoted to an arm 119 of a yoke 120 rockable about the shaft 84. This yoke 120 is connected by a second arm 121 to a bail 122 that is differentially positioned by cam slots 11 in the key levers 4 of the associated bank. After the tablets have been returned to their magazines at the beginning of an operation in the manner described above, a stud 141 on one of the universal bail levers 12 rocks a lever 136 counterclockwise by engagement with a byepass pawl 139 thereon. A shaft 130, controlled by a cam-slot 135 in the lever 136, is thus rocked counterclockwise and by means of slotted arms 131 embracing the pins 116 rocks the pins clockwise out of engagement with the sectors 115. The magazines, thus freed, move by gravity to zero position. The pins 116 are now differentially positioned by the depressed keys and, at the end of the downward movement of the keys, the stud 141 by engagement with a tail 142 of the lever 136 rocks the shaft 130 and arms 131 clockwise to re-engage the pins with selected teeth of the rack. During the return of the keys, the bails 122, yokes 120, arms 119 and pins 116 are restored to normal position and angularly position the magazines for selection of the appropriate tablets by the hooks 94 of the indicator bails 93. A restoring bail 146 carried by bell-cranks 147, 148 is given a left and right excursion at each operation by the engagement of the pins 81 within cam slots 149 in the bell-cranks. This bail serves on its left-hand excursion positively to restore the magazines by engaging arms 145 depending from their yokes, and on its right-hand excursion to restore the differential bails 122 by engaging arms 157 depending from their yokes 120. Totalizers. The machine is provided with a totalizer 155 operated by the arms 157 in the manner described in Specification 449,005.
