Abstract
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° 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.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
193 words
An actuator assembly for use with a bolt assembly of the kind having a tubular housing securable to a support, a lever rotatably mounted on said housing and a bolt slidably mounted within said housing and being responsive to rotation of said lever to move between an operative position and an inoperative position; said actuator assembly including a body member securable to said support separate from said housing, an actuator rotatably mounted on said body member, means releasably retaining said actuator in a rest position relative to said body member, a driving gear segment secured to said actuator for rotation therewith, mounting means secured to said body member against movement relative thereto, a driven gear member rotatably mounted on said mounting means, stop means on said mounting means limiting rotation of said driven gear member between two extreme positions, and a drive spindle connected to said driven gear member for rotation therewith and being connectable to said bolt assembly lever to cause rotation thereof, said driving gear segment engaging with and causing rotation of said driven gear member during part only of its rotation in either direction through 360° from said rest position.
Claim 2
Dependent Claim
193 words
An actuator assembly for use with a bolt assembly of the kind having a tubular housing securable to a support, a lever rotatably mounted on said housing and a bolt slidably mounted within said housing and being responsive to rotation of said lever to move between an operative position and an inoperative position; said actuator assembly including a body member securable to said support separate from said housing, an actuator rotatably mounted on said body member, means releasably retaining said actuator in a rest position relative to said body member, a driving gear segment secured to said actuator for rotation therewith, mounting means secured to said body member against movement relative thereto, a driven gear member rotatably mounted on said mounting means, stop means on said mounting means limiting rotation of said driven gear member between two extreme positions, and a drive spindle connected to said driven gear member for rotation therewith and being connectable to said bolt assembly lever to cause rotation thereof, said driving gear segment engaging with and causing rotation of said driven gear member during part only of its rotation in either direction through 360° from said rest position.
Claim 3
Dependent Claim
120 words
An actuator assembly according to claim 1, wherein said actuator is a rotatable barrel of a key operated tumbler lock, the keyway of said lock being accessible at one end of said body member, said mounting means comprises a plate secured to the end of said body member opposite said one end thereof, said barrel projects through and is rotatable relative to said plate, said driving gear segment is secured to said barrel to be located at the side of said plate remote from said body member, and said driven gear member is mounted on said plate at a location such that its rotational axis is laterally spaced from but is substantially parallel to the rotational axis of said barrel.
Claim 4
Dependent Claim
52 words
An actuator assembly according to claim 1, when co-operatively assembled with a said bolt assembly, said lever having a bore therein which receives said drive spindle, said drive spindle and lever bore having substantially complementary non-circular cross-sectional shape, and said drive spindle extends transverse to the line of movement of said deadbolt.
Claim 5
Dependent Claim
36 words
An actuator assembly according to claim 3, wherein said cross-sectional shape is such that said drive spindle is receivable within said lever bore at one rotational position only of said drive spindle relative to said lever.
Claim 6
Dependent Claim
27 words
An actuator assembly according to claim 3, wherein guide means on said actuator assembly co-operatively engages with said housing to retain said two assemblies in correct relationship.
