Abstract

1,173,200. Lock actuators. WESTING- HOUSE BRAKE & SIGNAL CO. Ltd. 26 June, 1968 [30 June, 1967], No. 30305/67. Headings F2E and F2F. In a lock actuator of the kind described in Specification 29890/67, viz., the piston-rod 5 is locked by spring biased rollers 16 and released by an annular piston 12, this release piston is actuated through an hydraulic circuit including conduit 34 and a further piston 36 which is moved either by air pressure through inlet 38, or screw 39.
