Abstract

337,100. Barr & Stroud, Ltd., and Macgill, C. D. Aug. 20, 1929. Transfer-mechanism.-A transfer-mechanism for the drums of step-by-step indicators is constituted by parts of known type located within the drums and so arranged as to impart movement with little or no shock by reason of approximately zero acceleration being imparted at each step to the driven element at initial contact, with velocity after such contact rising to a maximum and then falling to zero where final contact takes place. As shown a Geneva type of transfer mechanism is used, the driving element C, Figs. 1 and 2, being carried by a sleeve loose on a fixed shaft A. The element C has one or more pins 2 for engaging slots 3 in a star wheel D rotatable about an axis fixed relatively to the shaft A. The wheel D has integral therewith a pinion 4 engaging a toothed wheel 5 on the driven drum E. The driving element has a disc member engaging concave surfaces on the wheel D and the wheel D has slots so disposed that the pin 2 on entering imparts little or no movement. Specification 267,285 is referred to.
