ABSTRACT:
An actuator assembly in which the actuator is usually the rotatable barrel of a key operated tumbler lock. The actuator assembly is connectable through a non-circular drive spindle to any conventional deadbolt assembly of the kind having a tubular housing securable to support, a lever rotatably mounted on the housing and a deadbolt slidably mounted within the housing and responsive to rotation of the lever. A body member of the actuator assembly is securable to the support separate from the deadbolt housing and the lock barrel is rotatable relative to that body member. A gear segment secured to the barrel for rotation therewith is engageable with another gear segment rotatably carried on the body member, but only during part of its possible 360.degree. movement from the rest or locked position of the barrel. The other or driven gear segment has a drive spindle secured to it and that spindle engages within a bore of the bolt assembly lever to transmit rotation of the driven gear segment of the lever.
