Retrofit lock

A lockset mounted on a door having a transverse bore and another bore opening through an edge of said door and communicating with said transverse bore, said lockset having a bolt unit including a bolt housing supported in said other bore and a first bolt supported in said bolt housing for movement between projected and retracted positions relative to said one edge, said lockset having inside and outside operating assemblies respectively mounted on the inside and outside faces of said door, said lockset having a second bolt supported by one of said operating assemblies for movement between projected and retracted positions relative to the one edge, one of the bolts comprising said first and second bolt being a latch bolt and the other of said bolts being a dead bolt, said outside operating assembly including a rose having a bearing surface for engaging said outside face and means for maintaining said rose in alignment with said transverse bore, said outside operating assembly including an outside dead bolt operating unit having a cylindrical shell supported on said rose and projecting axially therefrom in a direction away from said door, a cylindrical dead bolt operator journaled in said shell, and means restraining said shell against rotation relative to said rose, said outside operating assembly including an outside latch bolt operator journaled on the projection portion of said shell and having a cylindrical bore receiving said projecting portion, said projecting portion being wholly contained within said outside operator.

A lockset for a door having a transverse bore therethrough and another bore opening through one edge of the door and communicating with the transverse bore, said lockset comprising a dead bolt and a latch bolt, one of the bolts comprising said dead bolt and said latch bolt being adapted for mounting in said other bore for movement between projected and retracted positions relative to the one edge, the other of said bolts being adapted for mounting in side-by-side relation to said one bolt and generally adjacent a face of the door for movement between projected and retracted positions relative to the one edge, a first latch bolt operator, a first housing for supporting said first latch bolt operator on one face of the door and in alignment with the transverse bore to move relative to the door and the first housing, a second latch bolt operator, a second housing for mounting said second latch bolt operator on another face of the door opposite the one face and in alignment with the transverse bore to move relative to the door and the second housing, said latch bolt being movable to a retracted position in response to movement of either of the latch bolt operators, and a first dead bolt operating unit operably connected to said dead bolt for moving said dead bolt between projected and retracted positions in response to operation of said first dead bolt operating unit, the improvement comprising said first dead bolt operating unit being mounted in fixed position on said first housing, said first latch bolt operator being journalled on said first dead bolt operating unit for angular movement relative thereto, and said first housing cooperating with said first latch bolt operator to define an envelope containing said first dead bolt operating unit.
