Abstract: An improved, key-operated locking device using an axially fixed rotating arm, employing the anvil and rotating keeper arm concept with the anvil extending laterally from the housing. The keeper arm, with lock cylinder assembly, is firmly retained within the housing through the use of a retaining pin, and is rotatable within the lock housing to move from the lock-closed to lock-opened positions in order to confine or release the slide of a slide fastener on a zipper-type closing fabric bag, utilizing a lower detent pin having a stepped cylinder shape located axially in the tubular bore in the lock housing, which is resiliently biased against the distal end of the lock cylinder assembly, with the smaller diameter end projecting along the axis into the axial keyway just past the lowermost tumbler of the lock cylinder assembly. This pins serves to defeat attempts at unauthorized access by lock picking.

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
