Abstract
Apparatus for causing a rotatable actuator to effect unlocking of a window latch and then to swing the window sash open when the actuator is rotated in one direction. When the actuator is rotated in the opposite direction, it first causes the sash to swing closed and then causes the latch to lock and hold the sash in its closed position. In one embodiment, the actuator is effective to swing an arm and shift a slide for purposes of moving the sash and operating the latch. In another embodiment, the actuator rotates a lead screw which advances nuts for moving the sash and operating the latch.
