Abstract

A motorized operator drive is used with a window having a fixed frame and a movable sash, and a manually driven window operator mounted to the frame. The window operator includes an operator shaft rotatable to drive a linkage mechanism fastened to the sash to selectively move the sash relative to the frame to open or close the window. The drive comprises a housing having a motor end and an opposite nose end. A motor is mounted in the housing at the motor end and has an output shaft. A gear set is mounted in the housing including an input gear driven by the motor shaft and an output gear at the nose end. An adaptor is operatively engaged with both the output gear and the operator shaft to rotate the operator shaft in response to energization of the motor. A bracket is fixedly mounted to the window frame. A rubber grommet resiliently mounts a stud at the housing motor end to the bracket to provide isolation between the drive and the window.
