Abstract

An actuating cylinder having a fluid pressure operated piston member connected by a friction member to a push rod to which a brake shoe, or the like, may be attached as the output member. A force transfer lever is arranged between the piston and push rod to transmit the piston force to the output member with mechanical advantage only after the friction connection is overcome by resistance at the push rod, such as occurs by engagement of the brake shoe with the wheel of a railway vehicle.
