ABSTRACT:
A lockset for a door has a strike on the door frame and a latch bolt on the door panel. The latch bolt is reciprocable and is projected by a spring and preferably has a deadlatch operation. The latch bolt is retractable by rotation of an inner knob or of an outer knob. The outer knob is locked by a key lock controlling an axially movable plate engaged with the outer knob and interengageable with an outer escutcheon adjacent the outer knob. The key lock can move the plate out of engagement with the outer escutcheon and into engagement with the inner knob. A turn button in the inner knob can also move the axially movable plate.
