Abstract
Abstract A vehicle washing apparatus is disclosed which systematically regulates the cleaning operation to produce optimum results. The apparatus comprises a frame member having an opening to receive the vehicle with means provided to move one of said frame member and vehicle relative to each other. A horizontal cleaning brush is rotatably disposed within the frame member. A brush control system is provided for regulating the positioning of the brush relative to the vehicle during the cleaning cycle.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
286 words
A vehicle washing apparatus, comprising: a frame member having an opening adapted to receive a vehicle; a horizontal cleaning brush rotatable about a horizontal axis of rotation disposed in said frame member; contant speed motor means for rotating said brush at a constant speed; current sensing means for sensing an increase in current above a predetermined value drawn by said constant speed motor means, said increased current being caused by a greater than desired pressure contact between said brush and said vehicle; vertically adjustable mounting means for adjustably mounting said brush in said opening; counterweight means for partially counterweighting said brush and said vertically adjustable mounting means wherein said brush naturally descends under the force of gravity and contacts said vehicle being washed, said counterweight means allowing said rotating brush to descend into contact with said vehicle to achieve desired pressure contact between said brush and said vehicle; a brush lifting motor responsive to said current sensing means for lifting said vertically adjustable mounting means against the excess weight of said counterweight means when said current exceeds said predetermined value; clutch means responsive to said current sensing means for operably connecting said brush lifting motor with said vertically adjustable mounting means, said clutch means being actuated to transmit torque from said brush lifting motor to said vertically adjustable mounting means when said current exceeds said predetermined value; and movement means responsive to said current sensing means for causing relative movement in a first horizontal direction between said frame member and said vehicle during a representative cleaning cycle wherein said movement means is actuated when said current is below said predetermined value and said movement means is not actuated when said current is above said predetermined value.
Claim 2
Dependent Claim
286 words
A vehicle washing apparatus, comprising: a frame member having an opening adapted to receive a vehicle; a horizontal cleaning brush rotatable about a horizontal axis of rotation disposed in said frame member; contant speed motor means for rotating said brush at a constant speed; current sensing means for sensing an increase in current above a predetermined value drawn by said constant speed motor means, said increased current being caused by a greater than desired pressure contact between said brush and said vehicle; vertically adjustable mounting means for adjustably mounting said brush in said opening; counterweight means for partially counterweighting said brush and said vertically adjustable mounting means wherein said brush naturally descends under the force of gravity and contacts said vehicle being washed, said counterweight means allowing said rotating brush to descend into contact with said vehicle to achieve desired pressure contact between said brush and said vehicle; a brush lifting motor responsive to said current sensing means for lifting said vertically adjustable mounting means against the excess weight of said counterweight means when said current exceeds said predetermined value; clutch means responsive to said current sensing means for operably connecting said brush lifting motor with said vertically adjustable mounting means, said clutch means being actuated to transmit torque from said brush lifting motor to said vertically adjustable mounting means when said current exceeds said predetermined value; and movement means responsive to said current sensing means for causing relative movement in a first horizontal direction between said frame member and said vehicle during a representative cleaning cycle wherein said movement means is actuated when said current is below said predetermined value and said movement means is not actuated when said current is above said predetermined value.
Claim 3
Dependent Claim
38 words
The vehicle washing apparatus of claim 1, wherein said frame member comprises a horizontal top portion supported by a pair of lateral leg portions and said frame member is moved in a horizontal direction by said movement means.
Claim 4
Dependent Claim
291 words
A vehicle washing apparatus comprising: a frame member having an opening adapted to receive a vehicle; a horizontal cleaning brush rotatable about a horizontal axis of rotation disposed in said frame member; constant speed motor means for rotating said brush at a constant speed; current sensing means for sensing an increase in current above a predetermined value drawn by said constant speed motor means, said increased current being caused by a greater than desired pressure contact between said brush and said vehicle; vertically adjustable mounting means for adjustably mounting said brush in said opening; counterweight means for partially counterweighting said brush and said vertically adjustable mounting means wherein said brush naturally descends under the force of gravity and contacts said vehicle being washed, said counterweight means allowing said rotating brush to descend into contact with said vehicle to achieve desired pressure contact between said brush and said vehicle; a brush lifting motor responsive to said current sensing means for lifting said vertically adjustable mounting means against the excess weight of said counterweight means when said current exceeds said predetermined value; an air actuated clutch operably connecting said brush lifting motor with said vertically adjustable mounting means, said air clutch being actuated simultaneously with said brush lifting motor by an air supply to transmit torque from said brush lifting motor to said vertically adjustable mounting means when said current exceeds said predetermied value; and movement means responsive to said current sensing means for causing relative movement in a first horizontal direction between said frame member and said vehicle during a representative cleaning cycle wherein said movement means is actuated when said current is below said predetermined value and said movement means is not actuated when said current is above said predetermined value.
Claim 5
Dependent Claim
291 words
A vehicle washing apparatus comprising: a frame member having an opening adapted to receive a vehicle; a horizontal cleaning brush rotatable about a horizontal axis of rotation disposed in said frame member; constant speed motor means for rotating said brush at a constant speed; current sensing means for sensing an increase in current above a predetermined value drawn by said constant speed motor means, said increased current being caused by a greater than desired pressure contact between said brush and said vehicle; vertically adjustable mounting means for adjustably mounting said brush in said opening; counterweight means for partially counterweighting said brush and said vertically adjustable mounting means wherein said brush naturally descends under the force of gravity and contacts said vehicle being washed, said counterweight means allowing said rotating brush to descend into contact with said vehicle to achieve desired pressure contact between said brush and said vehicle; a brush lifting motor responsive to said current sensing means for lifting said vertically adjustable mounting means against the excess weight of said counterweight means when said current exceeds said predetermined value; an air actuated clutch operably connecting said brush lifting motor with said vertically adjustable mounting means, said air clutch being actuated simultaneously with said brush lifting motor by an air supply to transmit torque from said brush lifting motor to said vertically adjustable mounting means when said current exceeds said predetermied value; and movement means responsive to said current sensing means for causing relative movement in a first horizontal direction between said frame member and said vehicle during a representative cleaning cycle wherein said movement means is actuated when said current is below said predetermined value and said movement means is not actuated when said current is above said predetermined value.
