ABSTRACT:
An axial-split pin tumbler-like lock mechanism for a pop-out lock of the type including a lock cylinder, a forwardly disposed operating spindle part rotatable in the cylinder, a rearwardly disposed sleeve held stationary in the cylinder and adjoining the operating spindle part defining a transverse interfacial plane, the operating spindle part including a shaft extending axially through the stationary sleeve, key operated spring pressed axially movable split-pin tumblers carried in bores in the operating spindle part and the stationary sleeve part and movable into positions ultimately serving to secure the operating spindle part and the stationary sleeve part against relative rotation and to free the operating sleeve part for rotation to operate the lock mechanism with the insertion of the proper key, includes a bolt holder removeably attachable with the stationary sleeve part and disposed rearwardly thereof, the holder having a bolt race extending transversely therein, and a lock bolt mounted in the race for transverse sliding movement therein between unlocking and locking positions, the bolt having means cooperating with coupling means on the distal end of the shaft for moving the bolt between such positions in response to rotation of the spindle operating part, the bolt holder being provided with means for affixedly securing by pins to the lock cylinder with the cooperating attachment between the bolt holder and stationary sleeve part maintaining the stationary sleeve fixed when assembled in the lock cylinder.
