ABSTRACT:
A guide structure straddling the path of a vehicle to be washed carries a vertically movable horizontal rotary brush, a pair of laterally displaceable first vertical rotary brushes moving in a first transverse plane perpendicular to that path, a pair of second vertical rotary brushes with shafts tiltably mounted on horizontally swingable main supporting arms pivoted to the structure downstream of the first pair, and a pair of vertical third rotary brushes mounted on horizontally swingable ancillary arms which intersect the main arms and are also pivoted to the structure downstream of the first pair. The first vertical brushes counterrotate in a sense tending to drive them apart on contact with a front surface of the vehicle; the initially separated second vertical brushes counterrotate in the opposite sense, so as to move toward each other, and their bristles interpenetrate in their position of closest approach, with their arms lying in a second transverse plane parallel to the first plane, into which they are urged by the relatively advancing vehicle. Upon the further advance of the front of the vehicle beyond that second plane, the second vertical brushes again separate; this separating movement is assisted by a pair of stationary guide rails, curving along arcs centered on the fulcra of the main arms, which are engaged by friction rollers on the tiltable shafts of the second brushes whenever the latter are deflected from their vertical attitude toward each other. The third brushes, hanging down to a lower level than the first and second brushes, normally rest against the sides of the guide structure and are held in that withdrawn position by interengagement of the main and ancillary arms until the second brushes are displaced from their normal position by the thrust of an oncoming vehicle whereupon the third brushes are free to engage the sides of the vehicle at the level of its wheels and also to sweep part of the vehicular rear surface.
