ABSTRACT:
A scrubbing unit for a vehicle-washing station, designed particularly for vehicles with vertically fluted sides, comprises an array of vertically superposed cylindrical brushes corotating on an upright support about horizontal axes which are parallel to the vehicular surface to be washed. The mutual spacing of the brush axes equals the diameter of their cylindrical bodies in the undeformed state of their bristles whereby these, on being urged against the vehicular surface to be scrubbed, are deflected against their direction of rotation to form a nearly continuous working area. Two such units mounted on the support alongside each other, with vertical staggering of their brush axes, insure uniform scrubbing over the height of the engaged surface. The support is swingable about a pivotal axis parallel to the brush axis, thus allowing the scrubbing of inclined surfaces, and is mounted on an overhead carriage reciprocable along the lintel of a portal frame with freedom of rotation about a vertical axis to let the brushes sweep both the lateral and the transverse surfaces.
