LATCH BOLT OPERATING DEVICE HAVING IMPROVED SHIELD CONSTRUCTION TO DETER PROBE MANIPULATION Abstract of the Disclosure: A door latch construction has exterior and interior operators connected through a latch driving mechanism operable for extending a bolt from a door edge. The exterior operator includes a lock cylinder telescoped by a thickened, hardened metal guard collar with the guard collar longitudinally inwardly abutting a metal shield retaining the shield in- wardly against an exterior face of the door. The shield also extends inwardly of the door interior at least partially annularly around a portion of the latch driving mechanism thereby detering manipulation of the latch driving mechanism by penetration through the door exterior face. The lock cylinder longitudinally inwardly abuts the guard collar so that the guard collar retained between its lock cylinder abutment and its shield abutment is rotatable to deter exterior attack against the overall exterior operator.
