A mortise lockset incorporates an electrically actuated clutch (88,90,92) within the lock case (100). The clutch (88,90,92) selectively engages one latch operator (80) to permit access through a door equipped with the lockset. The lockset further includes a key rotatable cam (62) for retracting the latch (12;13). The lockset includes a lock bar (50) that permits retraction of the latch (12;13) by means external to the lockset. An extended throw deadbolt-like latch (12) is held in a retracted position by an auxiliary latch (40) and hook (42) until released by retraction of the auxiliary latch (40). The latch (12) incorporates a recessed roller (16) in the projected end (14) of the latch (12) to facilitate latch deployment. <IMAGE> |
