324 words
A vehicle washing apparatus including: an overhead substantially rectangular track means; a carriage mounted for movement about said track means; a rotatable nozzle assembly mounted on said carriage below said track assembly, said nozzle assembly including a plurality of nozzles below said track means as said carriage moves about said track means; means for supplying liquid under pressure to said nozzles which issues as sprays from said nozzles and the reaction fOrces of the sprays on said nozzles causing rotation of said nozzle assembly; a drive wheel rotatably mounted on said carriage and engaging said track means; and transmission means connecting said nozzle assembly to said wheel for rotating said wheel when liquid under pressure is supplied to said nozzles and said nozzle assembly is rotated and for causing the carriage to be moved about said track, said track means comprising a bottom flange having horizontal top and bottom surfaces, said carriage having roller means engageable with the top surface of said bottom flange for movably supporting said carriage on said flange, said drive wheel being rotatable about a horizontal axis and having a peripheral surface engaging the bottom surface of said bottom flange, said carriage having a vertical support means depending therefrom, said rotatable nozzle assembly being rotatably mounted on said support means at a location spaced downwardly of said drive wheel, said drive wheel and said rotatable nozzle assembly having first and second shafts, respectively, rotatable therewith, a speed reducing transmission connecting said shafts, said speed reducing transmission including a third shaft secured to said support means, first flexible means connecting said second shaft to said third shaft for causing said third shaft to rotate when said second shaft is rotated at a slower speed than said second shaft, and second flexible means connecting said third shaft to said first shaft for causing said first shaft to rotate when said third shaft is rotated at a slower speed than said third shaft.
