A lock assembly including a novel retaining strap for securing a lock cylinder within the assembly. The lock assembly is designed so that one of two different degrees of bolt extension can be chosen during assembly of the device. In addition the assembly incorporates a dowel pin to increase the strength of the joint between the lock bolt and a lock bolt extension connected to the lockbolt.

A lock assembly comprising: an exterior housing havng a circular opening on the front surface thereof, a substantially cylindrical bore concentric with the opening and having a diameter slightly greater than the opening so as to form a shoulder therebetween, a substantially rectangular bore extending radially from the cylindrical bore and a longitudinal groove formed in the cylindrical bore slightly offset from the rectangular bore, said housing including a first mounting surface adjacent one side of the rectangular bore and a second mounting surface adjacent the other side of the rectangular bore; a hardened cylinder cap having a stepped peripheral surface, said cap being located within the cylindrical bore and extending through the opening, whereby the stepped surface abuts the shoulder; a lock cylinder assembly including a cylindrical body disposed within the cylindrical bore, a first radial extension which is disposed within the rectangular bore and carries a plurality of cylinder pins and an alignment extension having a first surface which abuts the portion of the longitudinal groove and a second surface which is substantially adjacent to and extends inward beyond the first mounting surface of the housing; and a restraining strap secured to the first and second mounting surfaces, said restraining strap including a middle portion which contacts the rear surface of the first extension of the lock cylinder assembly and biases the lock cylinder assembly tightly against the inside surface of the cylinder cap, a downwardly extending flange adjacent to the end of the strap secured to the second mounting surface and having a curved lower surface which abuts the curved surface of the cylindrical body to bias the alignment extension into the groove, the lower surface of the end of the strap secured to the first mounting surface abutting the second surface of the second extension and forcing the first surface of the second extension against the groove, whereby the lock cylinder assembly is accurately and securely positioned both longitudinally and axially within the housing.
