ABSTRACT:
Method and wrap around car wash apparatus are disclosed for maintaining uniform crush pressure of a rotary brush against a predetermined surface area of an advancing vehicle. A constant counterclockwise torque is produced on an outer arm by means of a rotating gear connected to the outer arm and a rack driven by a first pneumatic cylinder. After the rotary brush passes around the front edge of the vehicle, an inner arm pivotally connected to a support and the outer arm rotates counterclockwise until a maximum knuckled relationship between the inner and outer arms is attained. As the rotary brush, rotating clockwise, passes around the rear of the vehicle, the rotary brush bites into the rear corner producing a reaction force which causes the inner arm to be forced counterclockwise against a compression spring. The compression spring then boosts the inner arm in the clockwise direction, causing the rotary brush to be pushed into the rear end of the vehicle. The inner arm is then rotated clockwise to push the rotary brush against the rear end of the vehicle as the outer arm rotates counterclockwise, passing the rotary brush along the rear end of the vehicle. A telescoping member parallel to the inner arm and connected between an intermediate point of the outer arm and the support limits clockwise rotation of the outer arm as a function of clockwise rotation of the inner arm.
