Abstract: A windshield wiper and wiper support frame for extended side view mirrors for trucks and the like. The windshield wiper is supported upon a U-shaped frame fitted between the mirror and the truck and having legs secured to the mirror on lugs which extend from the mirror and provide for a pivotal connection for a standard mirror support frame connected to a truck. The windshield wipe is comprised of a pneumatic cylinder supported on the wiper support frame. A reciprocable piston has an operating rod connected by a connecting head to the blade for quick connection. Push-pull single stroke operation of the wiper across the face of the mirror for reciprocal wiping action is provided by remote control valve means positioned inside the truck cab for control of pneumatic pressure provided through air lines connecting the cylinder with a standard source of pneumatic pressure.
