Abstract

Abstract A vehicle wrap-around rotary brush-type cleaning assembly having a first arm pivotally mounted at one side of the path of a vehicle and a second arm pivoted thereto carrying rotatable brush means at one end. Spring tensioning means connect the first arm to the frame and the second arm to the first arm to maintain the arms in a normal open position. A compression spring is positioned between the two arms to limit relative movement in one direction and urge the arms back to their normal position. A damping cylinder connected between the arms by a pin and slotted plate connection permits relative initial movement between the arms prior to any damping taking effect. The brush moves across the front, along the side and across the back of a vehicle. Two brush assemblies may be disposed directly opposite each other on each side of the path with the brushes in overlapping relation to clean both sides of a vehicle.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 242 words
A vehicle washing apparatus comprising a. supporting frame means along a predetermined path of a vehicle to be washed, b. a first arm pivotally mounted at one end to said frame means at a point outside the path of the vehicle, c. a second arm pivotally connected adjacent one end to the opposite end of said first arm, d. rotatable brush means mounted at the opposite end of said second arm, said brush means being adapted to move across the front, along the side and across the back of a vehicle, e. a first tension means connected to said first arm and said frame means to normally maintain said first arm in a position extending generally along said path at one side thereof, f. a second tension means connected to said first arm and said second arm to normally maintain said second arm in a position extending generally transversely of said path whereby said brush means is in a position to be contacted by a vehicle moving along said path, g. and compression bearing means positioned between said one end of said second arm and said first arm to limit the relative movement between said arms in one direction and to urge said second arm back towards its normal position with respect to said first arm after said second arm has been moved out of its normal position through initial contact of said brush means by a vehicle moving along said path.
Claim 2
Dependent Claim 242 words
A vehicle washing apparatus comprising a. supporting frame means along a predetermined path of a vehicle to be washed, b. a first arm pivotally mounted at one end to said frame means at a point outside the path of the vehicle, c. a second arm pivotally connected adjacent one end to the opposite end of said first arm, d. rotatable brush means mounted at the opposite end of said second arm, said brush means being adapted to move across the front, along the side and across the back of a vehicle, e. a first tension means connected to said first arm and said frame means to normally maintain said first arm in a position extending generally along said path at one side thereof, f. a second tension means connected to said first arm and said second arm to normally maintain said second arm in a position extending generally transversely of said path whereby said brush means is in a position to be contacted by a vehicle moving along said path, g. and compression bearing means positioned between said one end of said second arm and said first arm to limit the relative movement between said arms in one direction and to urge said second arm back towards its normal position with respect to said first arm after said second arm has been moved out of its normal position through initial contact of said brush means by a vehicle moving along said path.
Claim 3
Dependent Claim 18 words
A vehicle washing apparatus according to claim 1 wherein said first and second tensioning means comprise tension springs.
Claim 4
Dependent Claim 24 words
A vehicle washing apparatus according to claim 2 which includes means for adjusting the tension of each of said first and second tension springs.
Claim 5
Dependent Claim 23 words
A vehicle washing apparatus according to claim 1 wherein said compression biasing means comprises a compression spring attached to one of said arms.
Claim 6
Dependent Claim 22 words
A vehicle washing apparatus according to claim 1 which includes a damping cylinder connected between said first arm and said second arm.
Claim 7
Dependent Claim 57 words
A vehicle washing apparatus according to claim 5 which includes a plate having an elongated slot therein mounted on one of said arms and means connecting one end of said cylinder to said slot to permit said second arm to move a distance corresponding to the length of said slot prior to said damping cylinder taking effect.
Claim 8
Dependent Claim 32 words
A vehicle washing apparatus according to claim 1 wherein said arms when in their normal position prior to contact with a vehicle are in generally perpendicular relation with respect to each other.
Claim 9
Dependent Claim 264 words
A vehicle washing apparatus comprising a. a supporting frame means extending along each side of a predetermined path of a vehicle to be washed, b. a pair or rotary brush assemblies disposed directly opposite each other along said path, c. each said brush assembly including a first arm pivotally mounted at one end to said frame means at a point outside said path, d. a second arm pivotally connected adjacent one end to the opposite end of said first arm, e. rotatable brush means mounted at the opposite end of said second arm, said brush means being adapted to move across the front, along the side and across the back of a vehicle, f. a first tension means connected to said first arm and said frame means to normally maintain said first arm in a position extending generally along said path at one side thereof, g. a second tension means connected to said first arm and said second arm to normally maintain said second arm in a position extending generally transversely of said path whereby said brush means is in a position to be contacted by a vehicle moving along said path, h. and compression bearing means positioned between said one end of said second arm and said first arm to limit the relative movement between said arms in one direction and to urge said second arm back towards its normal position with respect to said first arm after said second arm has been moved out of its normal position through initial contact of said brush means by a vehicle moving along said path.
Claim 10
Dependent Claim 264 words
A vehicle washing apparatus comprising a. a supporting frame means extending along each side of a predetermined path of a vehicle to be washed, b. a pair or rotary brush assemblies disposed directly opposite each other along said path, c. each said brush assembly including a first arm pivotally mounted at one end to said frame means at a point outside said path, d. a second arm pivotally connected adjacent one end to the opposite end of said first arm, e. rotatable brush means mounted at the opposite end of said second arm, said brush means being adapted to move across the front, along the side and across the back of a vehicle, f. a first tension means connected to said first arm and said frame means to normally maintain said first arm in a position extending generally along said path at one side thereof, g. a second tension means connected to said first arm and said second arm to normally maintain said second arm in a position extending generally transversely of said path whereby said brush means is in a position to be contacted by a vehicle moving along said path, h. and compression bearing means positioned between said one end of said second arm and said first arm to limit the relative movement between said arms in one direction and to urge said second arm back towards its normal position with respect to said first arm after said second arm has been moved out of its normal position through initial contact of said brush means by a vehicle moving along said path.
Claim 11
Dependent Claim 33 words
A vehicle washing apparatus according to claim 8 wherein said brush means are normally in overlapping relation with respect to each other prior to being contacted by a vehicle moving along said path.
