Abstract
A locking device for a reciprocating rod brake actuator movable between brake applying and brake releasing positions includes a pivoted pawl movable between locking and releasing positions for releasably locking the rod in its brake applying position. A spring normally biases the pawl to its locking position, and a fluid cylinder is operative when pressurized for moving the locking device to its releasing position. The rod is movable toward and away from the pawl, and is normally supported against movement away from the pawl by a releasable support. Release of the support frees the rod for free movement between its brake applying and releasing positions even though the pawl is in its locking position.
