Abstract: Mechanical release means for a spring-applied actuator comprising a threaded rod carried by the actuator and extending rearwardly into a fixed cylindrical socket of greater diameter than the rod and having a shoulder at the forward end of the socket, a rotatable hexagonal sleeve extending into the socket and engaging a hexagonal nut threaded onto the rod, the outer end of the sleeve being engaged by a cup-shaped, hexagonal cover member having an annular flange rotatably secured to the actuator housing, the cover member being rotatable so as to rotate the sleeve and drive the nut against the shoulder to draw the rod and actuator against the opposing force of the spring, the cover member serving also to exclude dirt and moisture from the housing. The release means including jam-type lock means releasable by mere rotation of the cover in a brake-releasing direction.
