Abstract
An assembly for opening and closing a window sash from and against a window frame including a motor mounted to a window sash and having an output drive shaft, an operator arm having one portion pivotally connected to the sash and a second portion operably connected to the frame, and a drive train operably connecting the motor drive shaft to the output arm for controlling pivotal movement thereof in relation to the sash. A clutch mechanism permits the operator arm to be selectively disconnected from the drive train to allow the sash to be manually opened. A housing, disposable in a cavity defined in a generally rectangular box shape on a sash side, encloses the motor, drive train, and clutch mechanism. The housing has finger-jointed ends which are adhesively bonded to matching finger-joints formed on opposite sides of the sash cavity.
