Abstract
A window lock having a base with a rotatable cam member engageable with a keeper for locking windows, such as a double hung window and a handle member rotatable in generally the same direction as the cam member for moving the cam member between retracted and extended lock positions with motion-transmitting means between the handle member and cam member providing for movement of the handle member through a greater arc of movement than the cam member. Structurally interengaging parts function when the cam member is in extended locked position to prevent any movement of the cam member from the locked position by a force applied thereto other than by rotation of the handle member. The window lock, by means of connecting link means to a second cam member, provides a dual window lock with operation of both cam members from a single handle member.
