Abstract
Abstract A car wash installation comprising a housing having a suspended guide track for mounting an inverted U-shaped frame carrying a spray conduit reciprocable relative to a stationary vehicle. Four corner posts extend upwardly above the deck of the housing and are provided with horizontally extending spray wands normally extending parallel to the longitudinal axis of the vehicle in an inoperative position and pivotable approximately 90* to a position of use in front of and behind the vehicle for vertically traversing the front and rear ends of the vehicle. Two of the laterally spaced posts are carried by a carriage mounted beneath the deck of the housing. The carriage is movable lengthwise of the vehicle for positioning such posts in close proximity to one end of the vehicle for accommodating vehicles of various lengths.
