Abstract: A mortise lockset apparatus (10) that includes a retractable bolt (20) movably supported within a case (12). A handle (18) is pivotally supported on a hub (16) supported in the case, the hub being operably connected to the retractable bolt. The bolt is retracted by turning the door handle. A lock-out mechanism (22) is configured to prevent the handle from being turned when the lock-out mechanism is in an engaged position. The handle lock-out mechanism also includes a cam (29) movably supported in the case and operably connected to a motor (30). A sliding stop (34) is movably supported in the case and is engageable with the handle hub to prevent the handle hub and the handle from turning. The sliding stop is also engageable with a cam surface (40) of the cam. The motor is configured to move the sliding stop by rotating the cam. The cam rotational axis (42) is disposed between diametrically opposed portions of the cam surface to minimize space requirements for the assembly.

Abstract: A mortise lock assembly is provided for mounting in a door opposite a strike plate on a door jamb. The assembly includes an automatic deadbolt feature with a bolt retractor arm that directly contacts and applies inward retraction pressure to a latch bolt and a deadbolt in response to bolt retractor hub rotation to retract the latch bolt and the deadbolt. Two deadbolt stops engage two housing stops when the deadbolt reaches the deadbolt extended position and restrain the deadbolt against further outward movement. Coil extension springs continuously bias the deadbolt and the latch bolt against retraction. A dead lock blocker releasably holds the deadbolt in the deadbolt extended position. The bolt retractor arm is additionally engageable with the blocker to release the blocker in response to bolt retractor hub rotation. A trigger releasably engages and retains the deadbolt in the deadbolt retracted position.
