Abstract
Abstract A scrubber for an automotive vehicle. The scrubber includes a brush, pivot and centering assembly. The brush scrubs the vehicle. The pivot allows the brush to change angular orientation. The centering means urges the brush toward a single predetermined angular orientation. In this way, should a vehicle drive into the brush, the brush may pivot with the force applied to it, reducing the chance that the brush or the vehicle will be damaged. The centering mechanism, however, urges the brush toward a predetermined angular orientation so that, absent an external force applied to the brush, the brush will be in a predetermined position ready for scrubbing the vehicle.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
118 words
A scrubber for an automotive vehicle comprising, in combination: a frame; brush means for wiping said vehicle, said brush defining an angular orientation; extension means for pushing said brush means toward said vehicle, said extension means including a first extension arm, interconnected to said brush means , and a second extension arm, interconnected to said frame, said angular orientation of said brush being defined by said first arm with respect to said frame, said first and second arms being slidably interconnected, whereby said first arm may slide along said second arm toward said automotve vehicle; pivot means for allowing said brush means to change angular orientation; and centering means to urge said brush toward a predetermined angular orientation.
Claim 2
Dependent Claim
118 words
A scrubber for an automotive vehicle comprising, in combination: a frame; brush means for wiping said vehicle, said brush defining an angular orientation; extension means for pushing said brush means toward said vehicle, said extension means including a first extension arm, interconnected to said brush means , and a second extension arm, interconnected to said frame, said angular orientation of said brush being defined by said first arm with respect to said frame, said first and second arms being slidably interconnected, whereby said first arm may slide along said second arm toward said automotve vehicle; pivot means for allowing said brush means to change angular orientation; and centering means to urge said brush toward a predetermined angular orientation.
Claim 3
Dependent Claim
54 words
A scrubber as claimed in claim 1 further comprising spindle bearing means interconnecting said second extension arm to said frame for allowing said second extension arm to pivot about said spindle bearing means, whereby said brush means may be moved substantially transversely to said predetermined angular orientation without causing substantial damage to said scrubber.
Claim 4
Dependent Claim
67 words
A scrubber as claimed in claim 2 wherein said centering means comprises a roller on a track, said roller interconnected to said second arm and said track being interconnected to said frame, said track including first and second downwardly inclined segments, said segments, defining upper and lower sections, and said lower sections of said first and second downwardly inclined segments meeting to cooperatively define a lower joint.
Claim 5
Dependent Claim
45 words
A scrubber as claimed in claim 3, wherein said track includes a central position and said scrubber further comprises a spring, interconnected to said roller, to further urge said roller toward said central position and thus urge said brush means toward said predetermined angular position.
Claim 6
Dependent Claim
24 words
A scrubber as claimed in claim 4 further comprising a pneumatic cylinder for moving said first extension arm toward a wheel of said vehicle.
Claim 7
Dependent Claim
28 words
A scrubber as claimed in claim 5 further comprising a pneumatic cylinder for sliding a first extension arm along said second arm toward said wheel of said vehicle.
Claim 8
Dependent Claim
101 words
A scrubber for an automotive vehicle, said vehicle having rotatable wheels and oriented for rectilinear motion comprising, in combination: rotating brush means for wiping said vehicle; a rotating member for rotating said rotating brush means; biasing means for orienting the axis of rotation of said rotating member substantially parallel to the axis of rotation of the wheels of said vehicle; and a single pivoting member for allowing angular displacement of said rotating member about a vertical axis, wherein said rotating member may be displaced to subtend an angle with respect to either side of said biased orientation of said rotating member.
Claim 9
Dependent Claim
101 words
A scrubber for an automotive vehicle, said vehicle having rotatable wheels and oriented for rectilinear motion comprising, in combination: rotating brush means for wiping said vehicle; a rotating member for rotating said rotating brush means; biasing means for orienting the axis of rotation of said rotating member substantially parallel to the axis of rotation of the wheels of said vehicle; and a single pivoting member for allowing angular displacement of said rotating member about a vertical axis, wherein said rotating member may be displaced to subtend an angle with respect to either side of said biased orientation of said rotating member.
Claim 10
Dependent Claim
134 words
A scrubber for an automotive vehicle, said vehicle having rotatable wheels and oriented for rectilinear motion, comprising, in combination: rotating brush means for wiping said vehicle; a rotating member for rotating said rotating brush means; support means for supporting said rotating member; biasing means for orienting the axis of rotation of said rotating member and said support means substantially parallel to the axis of rotation of the wheels of said vehicle; a single pivoting member connected to said support means for allowing angular displacement of said support means and said rotating member about a vertical axis, wherein said support means and rotating member may be displaced to subtend an angle with respect to either side of said biased orientation of said support means and rotating member; and a frame for supporting said pivoting member.
Claim 11
Dependent Claim
134 words
A scrubber for an automotive vehicle, said vehicle having rotatable wheels and oriented for rectilinear motion, comprising, in combination: rotating brush means for wiping said vehicle; a rotating member for rotating said rotating brush means; support means for supporting said rotating member; biasing means for orienting the axis of rotation of said rotating member and said support means substantially parallel to the axis of rotation of the wheels of said vehicle; a single pivoting member connected to said support means for allowing angular displacement of said support means and said rotating member about a vertical axis, wherein said support means and rotating member may be displaced to subtend an angle with respect to either side of said biased orientation of said support means and rotating member; and a frame for supporting said pivoting member.
Claim 12
Dependent Claim
24 words
A scrubber as claimed in claim 8 wherein said pivoting member further comprises spindle bearing means for interconnecting said pivoting member to said frame.
Claim 13
Dependent Claim
112 words
A scrubber as claimed in claim 8 wherein said biasing means comprises: two inclined members, said inclined members substantially forming a V-shaped track transversely mounted on said support means; roller means interconnected to said frame, said roller means being biasedly positioned to a rest position in a low portion of said V-shaped track when said rotating member and support means are in said biased orientation, whereby angular displacement of said rotating member and support means from said biased orientation causes displacement of said roller means along one of said inclined members, and said roller means returns said rotating member and support means to said biased orientation upon returning to said rest position.
Claim 14
Dependent Claim
49 words
A scrubber as claimed in claim 10 wherein said biasing means further comprises a spring interconnected to said roller, said spring urging said roller to said rest position in said track by positioning said rotating member and support means in said biased orientation in response to said angular displacement.

Dependent Claim
22 words
A scrubber as claimed in claim 8 wherein said support means includes extension means for pushing said brush means toward said vehicle.
