Abstract
An operating mechanism of a casement window includes a handle for rotating a worm shaft, which in turn rotates an inner gear, an annular gear and a crank arm to open a window. The crank arm is mounted on spaced apart pins on a flange or extension of the outer gear, so that the arm can be reversed on the pins to change the direction of window opening.
