ABSTRACT:
A horizontal top brush for a vehicle laundering or finishing plant wherein a brush rotated by an hydraulic motor is mounted between the free ends of pivot arms carried by spaced vertical stanchions flanking a vehicle treatment location. Counterweight arms on the left and right sides of the wash lane have an axis of rotation which is spaced from the axis of rotation of the brush pivot arms. The counterweight arms are mechanically interconnected with the brush arms by sector gears, an arrangement which permits all of the brush and counterweight arms to lie on one side of the vertical support stanchions. The brush arms are slotted to permit the counterweight arms to pass through them. Brush position relative to the vehicle is varied as a function of brush motor reaction which in turn is a function of brush contact pressure or depth. Electromagnetic sensors on a torque arm carrying the brush motor casing sense angular displacement of the torque arm relative to the brush support arm and vary brush position to maintain a desired contact pressure.
