ABSTRACT:
A cylindrical lock has a casing mounted in a transverse opening in a door and includes an outer knob spindle sleeve which extends axially outwardly from the casing. An outer rose liner received on the sleeve has spurs which engage the outer face of the door to secure it against rotation relative to the door. A tab on the rose liner received in a groove in the sleeve prevents rotation of the sleeve and casing relative to the outer rose liner. An outer thimble threaded onto the sleeve retains the outer rose liner and an outer rose, which covers it, in assembly with the sleeve. A projection on the outer rose received in a recess in the outer rose liner prevents rotation of the rose relative to the rose liner. The thimble conceals the latter connection and has a slot in its inner end which receives a portion of the locking tab to secure the thimble against rotation relative to the rose liner and the sleeve.
