  • Vehicle reciprocating spray washing apparatus
    Patent number: 4788993
    Abstract: Vehicle washing apparatus positioned above or at the side of the path followed by a vehicle to be washed. For side washing apparatus, pairs of spaced nozzles are reciprocated in a vertical plane to provide vertical coverage. The nozzles of a pair are angled toward each other, so that one nozzle sprays the front of the vehicle as the vehicle approaches, both nozzles spray the side of the vehicle as the vehicle passes, and the other nozzle sprays the rear of the vehicle as it departs. For top washing apparatus, the pairs of spaced nozzles are reciprocated in a horizontal plane to provide horizontal coverage. The angle nozzles contribute to the washing of the front and rear of a vehicle in addition to washing the top surfaces.
