First Claim
1. An adjustable backset deadbolt including a sleeve assembly, a deadbolt movable within said sleeve assembly between extended and retracted positions, a rear case adjustably mounted onto said sleeve assembly, a swivel rotatably mounted in said rear case, a retractor movable in said rear case and in engagement with said swivel and adjustably attached to said bolt, rotation of said swivel causing translational movement of said retractor and bolt to thereby move said bolt between extended and retracted positions,backset adjustment means on said bolt and retractor including spaced openings on said bolt and a cooperating engagement means on said retractor positionable in either of said spaced openings, with each opening being arranged to provide for bolt extension at a specific backset,backset adjustment means on said sleeve assembly and rear case, operable independently of the backset adjustment means on said bolt and retractor, said sleeve assembly and rear case backset adjustment means including means thereon for permitting relative movement therebetween, independent of backset adjustment movement between said bolt and retractor, and for engaging said sleeve assembly and rear case in one of two backset positions in which the combined length of the engaged sleeve assembly and rear case is different.

Abstract
An adjustable backset deadbolt has a casing formed of a sleeve assembly and a rear case. These two elements are independently adjustable to two different backset positions. A deadbolt is movable within the sleeve assembly between extended and retracted positions. There is a swivel rotatably mounted in the rear case and connected by a retractor to a pair of spaced adjustable backset openings in a rearward extension of the deadbolt. Rotation of the swivel provides translational movement of both the retractor and the deadbolt between the extended and retracted positions. The backset adjustment of the deadbolt is brought about by moving the retractor to one of two openings in the deadbolt extension and this adjustment is independent of the adjustment of the backset length of the casing.
