Abstract

A lock for windows or other structures having relatively movable parts and having a lock casing and a keeper separable therefrom. A handle pivotally mounted on the casing carries a cam finger rotatable by planetary gear means including a stationary arcuate gear and a gear rotatable with the cam finger whereby, as the handle is pivoted to a locking position, the cam finger is given bodily movement to a position in alignment with the keeper and is also rotated between outward and inward positions to pick up the keeper and move it to a locked position within the casing.
