Abstract
A transverse retaining plate in the lever handle shank fits in a circumferential groove on the inside of the handle body and holds the lever handle on the shank. A key cylinder in the body handle has a bible which fits in a longitudinal slot in the handle. A resilient block is disposed in the slot in a position between the bible and the shank hub to hold the cylinder in position. The block also serves as a spring, biasing the retaining plate toward the groove.
