Abstract
A lock assembly with a lock spindle extending perpendicular from the internal lock mechanism and the door. A knob or lever is operably connected to the spindle such that rotation thereof operates the lock mechanism. In order to eliminate any movement between the spindle and knob or lever and thereby eliminate rattle or inoperative rotation of the knob, a bow spring is longitudinally mounted to the spindle. The ends of the spring are retained on the spindle as the spring bows radially outwardly from the spindle to frictionally engage an inner wall of the knob or lever.
