Claim 1
Independent Claim
288 words
Apparatus for washing vehicles in a streak-free process, consisting essentially of first, second and third arch-like body members each having top and side portions of height and width dimensions allowing a vehicle to move therethrough, support and quide means secured to said arches to support them upright and also to guide a vehicle through the arches, said three arches being spaced apart and in alignment with each other so that a vehicle can be driven therethrough, conduit means and inwardly directed nozzles on the top and side portions of each arch, first detergent means associated with said conduit means and nozzles of said first arch supplying an acidic detergent to said nozzles of said first arch in a pH range of 2 to 5 for initial washing of a vehicle, second detergent means associated with said conduit means and nozzles of said second arch supplying an alkaline detergent to said nozzles of said second arch in a pH range of 10 to 13 for further washing a vehicle and neutralizing said acidic detergent, water rinse means associated with said conduit means of said third arch supplying pressured water in a final step to said nozzles of said third arch for rinsing the detergents from the vehicle, containers for each of said first and second detergent means having communication with said conduit means and nozzles, electrically operated valved control means in said conduit means arranged to be energized at selected positions of a vehicle for sequential operation of said first detergent means, said second detergent means, and said water rinse means, pressure means associated with said conduit means for pressurizing said first and second detergent means and rinse means, and actuating means for said electrically operated valved control means.
