Abstract: 414,714. Cash registers. WALLENTIN, S. M., Hojdgatan, M÷lndal, Sweden. Nov. 10, 1932, No. 31761. [Class 106 (i).] In a cash register having a separate amount indicating or registering system for each denomination, the actuating means for each system includes a series of bodies slidable as a unit in both directions of a guideway, and moved by a spring or the equivalent from zero position to a position determined by setting means. The invention is described as applied to a differentially set, independently operated machine, the mechanism for each denomination including a continuous tube 6-8 within which plungers 14, 15, 24, separated by balls 29, are slidable and maintained in compression by springs acting on the plungers 24. At the beginning of an operation, the balls and plungers are held in the positions they attained during the previous operation by the engagement of pawls 38 with rack teeth 16 formed on the plungers 14. The amount and transaction having been set up by adjustment of slidable finger plates G, the main shaft 35 which has been released by the setting of the transaction, is given one revolution by a hand crank or other means. A pair of cams 36 on the main shaft co-operate with arms 37 to rock a pair of levers 30 first upwardly and then downwardly. During the upward excursion a bail 31 co-operates with arms 32 projecting from the plungers 14 to return the slidable systems to zero position. During the return excursion, the pawls 38 are disabled to allow the slidable systems to descend until arrested by the setting means ; the pawls are then returned into engagement with their racks and the setting-means are released. Differentially-moved indicators.-The indicators for each denomination comprise a pair of cylindrical or prismatic drums A, B, viewable from opposite sides of the machine. The drums move axially with the plungers 14, 15 but are free to rotate relatively thereto on ball bearings 11. As the plungers move, the drums are rotated by helical members 9, 10 with the result that helically arranged numerals on the drums are presented serially at the reading positions 1, 2. Totalizers.-The machine is provided with a single totalizer comprising a series of wheels D connected by ratchet wheels 19 to racks 17 on the plungers 15. The amount set up during one operation is transmitted to the totalizer by the downward movement of the plungers 15 during the first part of the next succeeding operation. The racks are resiliently mounted on the plungers to enable them to wipe past the ratchet wheels during the upward movement. Setting-means.-The setting-means for each denomination of the amount and for the type of transaction comprises a slidable finger plate G held in set position against the action of a spring 58 by a rack 55. A pawl 46 is resiliently mounted on each finger plate and serves to intercept one of the teeth on a toothed disc 49 rigid with the indicator drum A, while the latter is moving downwardly. The teeth on the disc are so shaped as to wipe past the pawl during the zeroizing movement. Towards the end of an operation, the retaining racks 55 are rocked by the main shaft to permit the finger plates to return to normal position. Item-printing mechanism; voucherissuing.-The plungers 24 carry two sets of type E, F for printing on a voucher and a record strip, respectively. The voucher strip 63 passes from a roll 65 over a guide-plate 66 and between movable and stationary knives 69, 70 to the type. The strip is fed by a comb 77 projecting from a plunger 74 slidable within a pipe 73 into which the plunger is normally urged by a spring 79. The inner end of the pipe is curved to surround the main shaft 35 about which it is freely rotatable. An arm 81 projects from the main shaft into the pipe and during the rotation of the shaft engages the end ball of a series contained within the pipe to force the plunger outwardly and thus feed the strip. Towards the end of the rotation of the shaft, the arm wipes past the ball and the spring 79 causes the pipe to rock upwardly and the plunger to return thereinto. The rocking of the pipe, through a pin 87 and arm 84 operates the knife 69 to sever the voucher.
