Abstract: A casement window operator includes a linear input mechanism configured to be mounted to a stationary frame of a casement window, a linear to rotary motion converter operably coupled to an output of the linear input mechanism, a gear reducer operably coupled to an output of the rotary motion converter, and a sash arm operably coupled to an output of the gear reducer to rotate in conjunction with the output of the gear reducer. The sash arm is configured to extend from the stationary frame of the casement window to a rotatable window sash of the casement window.

Abstract: A sliding operator handle includes an actuatable brake providing at least one braking position in which the actuatable brake is configured to contact a track and restrict sliding motion of the track mount along the track and at least one sliding position in which the actuatable brake is configured to reduce contact with the track and allow sliding motion of the track mount along the track, and a handle pivotably coupled to the track mount. The handle is configured to receive a manual input force to slide the track mount in either direction along the track, and being further configured to actuate the actuatable brake in response to the manual input force. The handle includes a neutral position corresponding to the at least one braking position of the actuatable brake and actuation positions to allow sliding motion of the track mount along the track in response to manual input forces.
