ABSTRACT:
A windshield washer and wiper assembly for cleaning a windshield of an automobile. The assembly is generally comprised of an elongated housing, a source of windshield washer fluid under pressure, a perforated bladder within the housing, means for washing the windshield mounted through the housing in contact with the bladder, a wiper blade mounted on the housing and means for deflating the bladder. The bladder, upon actuation of the washer fluid source, inflates with washer fluid, urging the washing means against the windshield while simultaneously disengaging the wiper blade from the windshield and leaking washer fluid onto the windshield. The bladder returns to a contracted state by the deflating means upon deactivation of the washer fluid source to return the wiper blade to the windshield surface.
