Abstract
A window operator for repositioning a window sash within a window frame. The window operator includes a crank handle for rotating a shaft with a pinion gear. The pinion gear operably engages with a rack containing cutouts, the rack having oppositely disposed first and second ends. The rack is translatable within a track disposed within the window frame. The window operator also includes an operator arm connectable between a first end of the rack and the sash wherein rotation of the shaft by the handle imparts movement to the rack and the operator arm, the rack and operator arm movement capable of transitioning the sash between a window open and a window closed position.
