Abstract
Mechanism for a lock bolt assembly of the kind including a housing, a bolt mounted on the housing for movement into and out of a strike engaging position, an actuator rotatably mounted on the housing, and a drive connection between the actuator and the bolt whereby operation of the actuator causes movement of the bolt. The drive connection includes an override clutch which can be caused to adopt either an engaged condition or a disengaged condition by operation of a key operated lock. In the engaged condition the actuator is drivably connected to the bolt, whereas in the disengaged condition that connection is broken. The clutch operates to resist rotation of the actuator when in the disengaged condition, but that resistance can be overcome by forced operation of the actuator after which the actuator can be rotated freely relative to other parts of the mechanism.
