ABSTRACT:
The latching bolt of a window lock is pivotally mounted on a slide to pivot between locked and unlocked positions. A reversible motor with a rotary drive shaft is adapted to reciprocate the slide outwardly and inwardly by means of a scotch yoke connection between the drive shaft and the slide, the scotch yoke being of the lost-motion type so as to permit the slide to shift independently of the drive. When the slide is shifted outwardly, the bolt is permitted to pivot to its unlocked position and, when the slide is shifted inwardly, the bolt is cammed to its locked position. A lever may be operated manually to unlock the bolt in the event there is a loss of power to the motor.
