Abstract

330,251. British Power Railway Signal Co., Ltd., Glenn, S. L., and Pierce, E. E. March 1, 1929. Divided on 330,241. Hand-levers, interlocking.-In an interlocking frame a push-button with a spring-pressed plunger is associated with each operating lever and is locked in normal position until the lever is moved to a definite position and when pushed inwardly to make the desired electrical contacts is then locked until the lever returns to normal. The pushbutton device 91 is shown associated with a miniature lever 1 of an interlocking frame as described in Specification 330,241. The push-button plunger 90 is locked by the engagement in locking faces 108 or 110 thereof of a spring-pressed collar 104 or 105 slidable on a rod 98 which is moved bv a cam web 102 on the electrical lock tappet or transmission bar 38 of the lever 1. The movement of the rod 98 disengages by means of a collar 106 that spring-pressed collar which is in engagement. The push-button 91 is returned by its spring 95 when the lever 1 is returned to normal.
