ABSTRACT:
A locking mechanism used to secure any number of window sashes closed against a window frame includes one or more keepers mounted to the window sash, and a tie bar having thereon a corresponding number of rollers, and an actuator assembly mounted to the window frame. The actuator assembly is configured to reciprocally move the tie bar and includes a housing and a handle lever and actuator arm pivotally mounted to the housing. A camming pin is coupled to the handle lever so that the rotation of the handle lever rotates the camming pin along an arc of a circle centered on the handle pivot. The pin extends into a slot formed in the actuator arm remote from an end coupled to the tie bar. As the camming pin moves along its arcuate path, its engagement with the slot urges the actuator arm in pivotal movement which in turn moves the tie bar.
