CA 2012329

A window operator and hinge structure for a casement window which can be simply factory pre-set for positioning of a window in either egress or wash modes, with switching between modes requiring no additional parts or special tools. The structure has a pivoted handle movable between a closed, inactive position flush with a sill cover and rotatable to an inclined, active position. The handle, in its pivoting movement, operates window locking structure and also controls the action of a brake, with release of the brake by raising of the handle to operative position. Motion-transmitting connections between the handle and linkage structure include the brake as well as the clutch, with the clutch effective to limit the torque that can be applied to the linkage. The handle can be moved to closed, inactive position with the window open so that no handle protrudes and this movement of the handle sets the brake so that a wind cannot move the window.
