Abstract
Abstract Car washing apparatus comprising an arch mounted for movement longitudinally of the car, and generally vertical brushes movable transversely across the arch from each side and supported from rails which are inclined downwardly toward the center of the arch. A brush which rotates about a horizontal axis is supported for vertical movement by the side posts of the arch.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
103 words
Car washing apparatus comprising an archway mounted for movement perpendicularly to the principal plane of the arch, a rotatable cylindrical brush mounted for vertical movement within the opening defined by the arch, rail means extending across the top of the arch, at least two generally vertical cylindrical brushes, and a carriage for each brush mounted to travel on said rail means, said rail means being inclined downwardly from the sides of said arch toward the center thereof, and said brushes being mounted to rotate about axes which are spaced from each other in a direction perpendicular to the principal plane of the arch.
Claim 2
Dependent Claim
103 words
Car washing apparatus comprising an archway mounted for movement perpendicularly to the principal plane of the arch, a rotatable cylindrical brush mounted for vertical movement within the opening defined by the arch, rail means extending across the top of the arch, at least two generally vertical cylindrical brushes, and a carriage for each brush mounted to travel on said rail means, said rail means being inclined downwardly from the sides of said arch toward the center thereof, and said brushes being mounted to rotate about axes which are spaced from each other in a direction perpendicular to the principal plane of the arch.
Claim 3
Dependent Claim
27 words
Car washing apparatus as claimed in claim 1 in which each carriage is equipped with an electrical motor connected to rotate the brush carried by that carriage.
Claim 4
Dependent Claim
64 words
Car washing apparatus as claimed in claim 1 in which said rail means comprises two rails which overlap each other at their inner ends, each pivotally and slidably attached at one end to the other rail and pivotally attached at the other end to one side of said archway, and power means for swinging said rails about the ends attached to said archway sides.
Claim 5
Dependent Claim
40 words
Car washing apparatus as claimed in claim 1 in which the weight of said vertical brushes and the inclination of said rails suffices to bring said vertical brushes to the inner ends of their paths of travel on the rails.
Claim 6
Dependent Claim
20 words
Car washing apparatus as claimed in claim 2 in which said electrical motors drive said vertical brushes in opposite directions.
Claim 7
Dependent Claim
30 words
Car washing apparatus as claimed in claim 1 comprising means near the center of said rail means for reversing the direction in which said electric motors drive said vertical brushes.
Claim 8
Dependent Claim
31 words
Car washing apparatus as claimed in claim 1 comprising means at the outer ends of said rail means for cushioning the impact of said carriages as they approach said outer ends.
Claim 9
Dependent Claim
24 words
Apparatus as claimed in claim 1 in which the slope of said rail means is steeper near its outer end than at the center.
Claim 10
Dependent Claim
33 words
Apparatus as claimed in claim 1 in which said rail means comprises vertically spaced upper and lower surfaces, and said carriages are mounted on rollers which travel between said upper and lower surfaces.
Claim 11
Dependent Claim
31 words
Apparatus as claimed in claim 8 in which each carriage is provided with a pair of auxiliary wheels and said rail is provided with vertical surfaces which engage said auxiliary wheels.
Claim 12
Dependent Claim
59 words
Apparatus as claimed in claim 1 comprising a switch positioned to be actuated by a carriage as it approaches the center of said archway, fluid pressure exerting means actuated by said switch, and an arm actuated by said fluid pressure means to return said carriage and the brush to the outside of said archway upon actuation of said switch.
