A combination door latch and deadbolt assembly includes an improved latch mechanism and deadbolt mechanism designed for use with doors having a variety of standard size backset and cross bore dimensions. The latch and deadbolt mechanisms are carried by escutcheons havings breakaway tabs at varying diametric positions to fit securely within door cross bores of different standard sizes. The latch mechanism further includes an improved mounting arrangement for left- or right-hand mounting and positive centering of lever-type door handles, together with a simplified cam-actuated latch retractor. The deadbolt mechanism includes an improved bolt linkage which provides a desired bolt throw when a relatively small door backset and/or cross bore size is used. The deadbolt mechanism further includes an improved thumb turn rotatable through ninety degrees between orientations representative of deadbolt position.

A combination door latch and deadbolt assembly, comprising: an inner escutcheon and an outer escutcheon; means for mounting said inner and outer escutcheons respectively on the inner and outer sides of a door in overlying relation with at least one cross bore formed in the door; a latch mechanism carried by said inner and outer escutcheons and including a retractable latch and means accessibly operable from at least one side of the door for retracting said latch; and breakaway tabs on said inner and outer escutcheons, said tabs being oriented to fit snugly into a door cross bore of a first diametric size and adapted to be broken off to permit assembly mounting onto a door having a cross bore of a second smaller size.
