A keyed lever handle for a cylindrical lock comprises a handle body which is rotatably mounted by its neck on the knob sleeve of the lock and is removably held by a retainer and is connected for rotation with the sleeve by a driver which releases under excess torque, either yieldingly or by break-away of a driver lug. An outward-extending body shell telescopically receives and supports an outer handle shell integral with a handle lever. The outer shell has an inward-extending end flange spaced from the end face of the body shell to define therebetween an inward-opening groove which receives a retainer for an end face closure mounted in the cylindrical open end of the assembled shells. The retainer may be a separate snap ring or an integral flange on the closure. The closure member receives a key-operated and removable core, and its rotative mounting permits different orientations to suit the hand of the door, and also permits the lever handle to rotate when drive is released under excess torque.

A door handle adapted to contain a key-operated lock mechanism comprising a hollow body having a neck adapted to be mounted on a knob sleeve or the like and having an outward-extending body shell terminating at a circular end face surrounding a circular body opening, an outer shell telescopically received over said body shell, fixed thereto, and having an end flange defining a circular opening, said flange being axially spaced from said end face of the body shell and defining therewith an inward-opening circumferential groove, means for rigidly interconnecting the body shell and the outer shell, an end closure member rotatably received within the end opening formed by said rigidly interconnected shells and containing or adapted to contain key-operated lock mechanism, and means engaged in said inward-opening circumferential groove for securing said end closure member in axially fixed rotatable relation with said assembled rigidly interconnected shells.
