Abstract
Abstract A wraparound brushing device 20 (FIGS. 1-4) has a linkage carrying a brush and urged toward a normal position by a spring and a counterweight. A top brushing device 120 (FIGS. 5 and 6) includes a pair of linkages at each side which fold as the brush rolls over the top of a car and then unfold to cause the brush to follow the rear surfaces of the car. Wraparound brushing devices 220 (FIG. 7), 320 (FIG. 8), 420 (FIG. 9) and 520 (FIG. 10) are moved around moving cars solely by the action of rotating brushes and constantly operative biasing means.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
156 words
In a wraparound brush device: a rotary brush, a frame adjacent a path of a car, a first arm pivotally mounted at a first end on the frame for movement between a normal position and a second position away from said path, second arm means carrying the brush at a first end thereof and mounted intermediate its ends to the second end of said first arm for movement between a normal position in which said brush is positioned in said path and a second position folded back along said first arm, holding means mounted adjustably on said frame, releasable means securing said holding means to said frame, elongated tension means helD by and extending from the holding means adjacent the first end of said first arm to the second end of said second arm, adjustment of said holding means on said frame serving to change the angle of the tension means relative to said second arm.
Claim 2
Dependent Claim
156 words
In a wraparound brush device: a rotary brush, a frame adjacent a path of a car, a first arm pivotally mounted at a first end on the frame for movement between a normal position and a second position away from said path, second arm means carrying the brush at a first end thereof and mounted intermediate its ends to the second end of said first arm for movement between a normal position in which said brush is positioned in said path and a second position folded back along said first arm, holding means mounted adjustably on said frame, releasable means securing said holding means to said frame, elongated tension means helD by and extending from the holding means adjacent the first end of said first arm to the second end of said second arm, adjustment of said holding means on said frame serving to change the angle of the tension means relative to said second arm.
Claim 3
Dependent Claim
15 words
The wraparound brush device of claim 1 wherein the tension means comprises a tension spring.
Claim 4
Dependent Claim
23 words
The wraparound brush of claim 1 wherein the tension means comprises a counterweight and a cable, the holding means comprising a cable guide.
Claim 5
Dependent Claim
27 words
The wraparound brush device of claim 1 wherein the first arm normally extends primarily transverse to said path, and the second arm extends primarily along said path.
Claim 6
Dependent Claim
29 words
The wraparound brush of claim 1 wherein the frame includes an overhead portion extending transversely of said path and the holding means is adjustably mounted on the overhead portion.
Claim 7
Dependent Claim
24 words
The wraparound brush of claim 1 wherein the first arm extends primarily along the path and the second arm extends primarily across the track.
Claim 8
Dependent Claim
15 words
The wraparound brush of claim 6 wherein the tension means extends across the first arm.
Claim 9
Dependent Claim
155 words
In a wraparound brush device, a rotary brush, a frame adjacent a path of a car, a first arm pivotally mounted on the frame for movement between a normal position extending primarily along one side of the path and a second position swung away from the path, a second arm carrying the brush on a free end thereof and pivotally mounted on the first arm at a point on the second arm intermediate the ends of the second arm for movement between a normal position extending primarily transversely of the first arm and a second position folded back along the first arm, and biasing means connected to the frame at a point between the first arm and said path and continuously urging the arms toward the normal positions thereof, the biasing means extending from the frame across the first arm and being secured to the end of the second arm remote from said free arm.
Claim 10
Dependent Claim
155 words
In a wraparound brush device, a rotary brush, a frame adjacent a path of a car, a first arm pivotally mounted on the frame for movement between a normal position extending primarily along one side of the path and a second position swung away from the path, a second arm carrying the brush on a free end thereof and pivotally mounted on the first arm at a point on the second arm intermediate the ends of the second arm for movement between a normal position extending primarily transversely of the first arm and a second position folded back along the first arm, and biasing means connected to the frame at a point between the first arm and said path and continuously urging the arms toward the normal positions thereof, the biasing means extending from the frame across the first arm and being secured to the end of the second arm remote from said free arm.
Claim 11
Dependent Claim
15 words
The wraparound brush device of claim 8 wherein the biasing means comprises a tension spring.
Claim 12
Dependent Claim
18 words
The wraparound brush of claim 8 wherein the first arm extends forwardly along said path from its pivot.
Claim 13
Dependent Claim
160 words
In a wraparound brush device, a rotary brush, a frame adjacent a path of a car, a first arm pivotally mounted on the frame for movement between a normal position extending primarily across said path and a second position swung away from said path, a second arm carrying the brush at one end thereof and pivotally mounted at a point intermediate the ends thereof on the first arm for movement between a normal position extending primarily transversely of the first arm and a second position folded back along the first arm, holding means mounted adjustably along the frame, elongated tension means extending from the holding means to the other end of the second arm and continuously urging the arms toward the normal positions thereof, and releasable means securing the holding means to the frame in adjusted position, adjustment of the holding means along the overhead portion serving to change the angle of the tension means relative to the second arm.
