ABSTRACT:
A mirror cleaning system includes a mirror with an exposed front surface and a mirror support assembly. A pair of vertically extending hollow, fiberglass pipes include an interior actuator and an exterior guide secured with respect to the support assembly. A cross piece has interior and exterior end blocks. Each block has a vertical aperture slidably received on the pipes for reciprocal movement upwardly and downwardly along the pipes. An elongated wiper arm of an elastomeric material is positioned in sliding contact with the front surface of the mirror during reciprocation of the cross piece. The interior actuator constitutes a magnetic rodless actuator with an internal magnet movable by air pressure for reciprocating the cross piece and wiper arm with respect to the front surface of the mirror. The interior actuator also includes an upper air line and a lower air line and a source of pressurized air and valve to effect the motion of the magnet. Upper and lower sensors at the opposite ends of the interior actuator function to reverse the air valve and the direction of air flow. When not in operation, the cross piece and wiper arms are at one end of the mirror with no visual impairment so as not to encumber the normal use of the mirror for maximum safety.
