Abstract: A self cleaning truck mirror has a housing which contains a tank for storing washer fluid. A wiper is mounted for reciprocation across the face of the mirror by a mechanism within the housing. The reciprocating mechansim includes a carriage screw provided with crossing helical opposite hand threads. The screw is rotated by a motor within the housing through a bevel gear arrangement. A limit switch is provided for parking the wiper. The mirror is provided with tubular supports for mounting on a truck body. The housing is rotatably mounted on the supports, and a motor driven gear drive within the housing allows the mirror to be rotatably adjusted with respect to the tubular supports. Limit switches control the range of adjustment. A pump motor within the housing supplies washer fluid from the tank to spray nozzles at the top of the mirror. All control wiring extends through the tubular supports for enabling control of all the motors from within the cab of the truck.
