ABSTRACT:
A mechanism for immobilizing an arming shaft to preclude axial movement of he shaft until its release is desired, comprising a base and rotor mounted thereon. The rotor holds hardened metal balls in engagement with a circumferential groove on the shaft to lock the shaft in position. The base, rotor and shaft are held in locked position by an arming wire. Compression springs acting between the base and rotor cause relative rotation thereof, when the arming wire is removed, to an unlocked position where the balls can be forced into apertures in the base and release the shaft for axial movement.
