Patent GB-677934-A (GB)
Abstract: 677,934. Cash-registers. GROSS, H., and GROSS, S. March 8, 1951 [March 30, 1950], No. 7961/50. Class 106 (i). The key coupler bar 16 of a key-operated cash register is initially moved into a preset position, e.g. by operating a presetting key 21, and the tips 36 of the coupling notches 35 of preset (partially depressed) amount key levers 14 are then so disposed in relation to the tip of the coupler bar that any amount key preset in error can be individually restored. The notches 35 are wider than the chamfered tip of the coupler bar and, in the preset positions of a lever 14 and the bar, the tip 36 of the notch 35 lies above the intersection of its arc Y with the arc X traversed by the tip of the bar which itself lies below the intersection. The lever 14 is therefore free to be restored although operable by the bar to register an item. Spring-loaded detents 30 hold the amount levers 14 resiliently in their normal and preset positions. The notches 35 taper inwardly so that the operated lever 14 and those coupled to it by the bar complete their movements together. The lever 20 of the presetting key 21 lifts the bar 16 into the preset position against the action of a return spring 19. A pawl 27 then locks the lever 20 and is tripped by a pin 40 on a supporting arm 15 of the coupler bar as the stroke of the amount levers 14 is completed, so that the bar is then free to return under the action of its spring 19 and to restore the actuated levers 14. A full-stroke pawl 47 controls movement of the coupler bar beyond the preset position.
