Claim 4

A rollover car washer comprising an inverted U-shaped frame arranged to travel over a car washing station, a rotative brush for scrubbing top and end surfaces of cars positioned in the washing station, the brush having a horizontal mounting shaft, and mounting mechanism for the brush including a pair of arms spaced from each other at opposite sides of the washing station, and axially aligned stub shafts for mounting said arms, the stub shafts being mounted inside of the frame at opposite sides oF the washing station and providing an axis of swing motion at a predetermined elevation, the length of said arms being sufficient to provide freedom for swinging movement of the brush toward either side of a position vertically below the axis of swinging motion at said elevation through a range extended higher than the topmost surface of the car in the washing station.

Claim 5

A rollover car washer as defined in claim 2 in which the mounting mechanism provides for free swinging of the brush under the action of gravity, and controllable lifting means for upwardly swinging the brush.

Claim 6

A rollover car washer as defined in claim 3 and in which the lifting means comprises a manually operable control means.

Claim 7

A rollover car washer comprising an inverted U-shaped frame having wheels mounting the washer on a supporting surface and providing for travel of the washer over a car washing station adapted to accommodate cars to be washed, a rotative brush for scrubbing surfaces of cars positioned in the work station, the brush having a horizontal mounting shaft, mounting mechanism for the brush including a pair of arms pivotted to the frame and spaced from each other at opposite sides of the washing station and providing for pivotal movement of the brush to a position providing for scrubbing of end surfaces of a car in said station when the washer travels on said wheels, wheel drive means for effecting travel of the washer over the supporting surface, and means for restraining tilting of the frame when the brush engages end surfaces of a car under the influence of travel of the washer, the tilt restraining means comprising a stop device mounted on the frame and projecting horizontally beyond a driven wheel in a position adjacent to the supporting surface, the projection of the stop device and the proximity thereof to the supporting surface providing for lifting of said driven wheel from the supporting surface upon tilting of the frame and thereby effect termination of the drive effect of said wheel.

Claim 8

A rollover car washer comprising an inverted U-shaped frame having wheels mounting the washer on a supporting surface and providing for travel of the washer over a car washing station adapted to accommodate cars to be washed, a rotative brush for scrubbing surfaces of cars positioned in the work station, the brush having a horizontal mounting shaft, mounting mechanism for the brush including a pair of arms pivotted to the frame and spaced from each other at opposite sides of the washing station and providing for pivotal movement of the brush to a position providing for scrubbing of end surfaces of a car in said station when the washer travels on said wheels, wheel drive means for effecting travel of the washer over the supporting surface, and means for restraining tilting of the frame when the brush engages end surfaces of a car under the influence of travel of the washer, the tilt restraining means comprising a stop device mounted on the frame and projecting horizontally beyond a driven wheel in a position adjacent to the supporting surface, the projection of the stop device and the proximity thereof to the supporting surface providing for lifting of said driven wheel from the supporting surface upon tilting of the frame and thereby effect termination of the drive effect of said wheel.

Claim 9

A rollover car washer comprising an inverted U-shaped frame arranged to travel over a car washing station adapted to accommodate cars to be washed, a rotative brush for scrubbing top and end surfaces of cars positioned in the work station, the brush having a horizontal mounting shaft, and mounting mechanism for the brush including a pair of arms providing for upward and downward swinging of the brush, an operators station on the frame, and means for manually swinging the brush on its mounting mechanism including a manually operable control organ connected with the mounting mechanism and positioned on the frame for convenient access by an operator in the operators station.

Claim 10

A rollover car washer comprising an inverted U-shaped frame arranged to travel over a car washing station adapted to accommodate cars to be washed, a rotative brush for scrubbing top and end surfaces of cars positioned in the work station, the brush having a horizontal mounting shaft, and mounting mechanism for the brush including a pair of arms providing for upward and downward swinging of the brush, an operators station on the frame, and means for manually swinging the brush on its mounting mechanism including a manually operable control organ connected with the mounting mechanism and positioned on the frame for convenient access by an operator in the operators station.

Claim 11

A rollover car washer as defined in claim 6 and further including drive means for effecting travel of the washer, and a drive control on the frame positioned for convenient access by an operator in the operators station.

Claim 12

A rollover car washer comprising an inverted U-shaped frame arranged to travel over a car washing station, a rotative brush for scrubbing top and end surfaces of cars positioned in the washing station, the brush having a horizontal shaft, and mounting mechanism for the brush including a pair of arms positioned inside of the frame and spaced from each other at opposite sides of the washing station, and pivot means for mounting said pair of arms on the frame and providing a pivotal axis at a predetermined elevation and for pivotal movement of the arms about said axis at said elevation through a range extending from a bottom pivotal position upwardly in either direction to a position higher than the topmost surface of the car in the washing station.

Claim 13

A rollover car washer comprising an inverted U-shaped frame arranged to travel over a car washing station, a rotative brush for scrubbing top and end surfaces of cars positioned in the washing station, the brush having a horizontal shaft, and mounting mechanism for the brush including a pair of arms positioned inside of the frame and spaced from each other at opposite sides of the washing station, and pivot means for mounting said pair of arms on the frame and providing a pivotal axis at a predetermined elevation and for pivotal movement of the arms about said axis at said elevation through a range extending from a bottom pivotal position upwardly in either direction to a position higher than the topmost surface of the car in the washing station.
