Abstract
The invention comprises a lever handle having a handle-shaft receiving cam which is used to displace a slider to effect the retraction of a latchbolt. A yoke is positioned between the cam and slider to accommodate, adjustably, for handle droop. The yoke has a tapped hole and receives a machine screw which also penetrates an arcuate slot in the slider. Displacement of the yoke relative to the slot, corrects the handle droop by causing the cam to be slightly tilted. Accordingly, the handle shaft in the cam is correspondingly rotated about its axis, and the handle is brought into alignment with the horizontal.
