Abstract
Abstract An apparatus and process for washing vehicles, particularly private sedans and station wagons. The apparatus comprises a carriage mounted about an enclosed track. The carriage moves about the periphery of a stationary vehicle. It supports a yieldable upright brush that engages the vehicle sides and a yieldable upper horizontal brush that engages the vehicle upper surfaces. Means is provided to lift the upper brush while the carriage moves across the rear of the vehicle. The washing process includes the step of lifting the brush and maintaining it at an elevated position as the brush traverses the rear of the vehicle.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
109 words
In an automatic washing facility for vehicles having a mobile unit that moves around the vehicle spraying a cleaning fluid onto the vehicle while a horizontally movable rotating side brush engages the side, back and front surfaces of the vehicle and a vertically movable rotating overhead brush engages the top surfaces of the vehicle; an actuator for raising the overhead brush to an up position and a control means responsive to the movement Of the mobile unit along the rear of the vehicle and operatively connected to the actuator for operating the actuator to raise the overhead brush as the mobile unit moves along the rear of the unit.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
201 words
An automatic washing facility for vehicles, particularly comprising: a floor surface for supporting the vehicle; an elongated continuous guide track fixed to the floor surface surrounding and spaced from the vehicle; a mobile unit supported by the floor surface and guided by the guide track for moving around the vehicle during each washing operation; a side frame pivotally mounted on the mobile unit for pivotal movement about a substantially vertical axis; an upright side brush rotatably mounted on the side frame for engaging the rear, side, and front surfaces of the vehicle as the unit moves around the vehicle a overhead frame pivotally mounted on the mobile unit for pivotal movement about a substantially horizontal axis; a horizontal brush rotatably mounted on the overhead frame for engaging the top surfaces of the vehicle as the unit moves around the vehicle; an actuator mounted on the unit operatively connected to the overhead frame for holding the horizontal brush in an elevated position, and control means responsive to the movement of the mobile unit along the rear of the vehicle for operating the actuator to hold the horizontal brush in the elevated position as the unit moves along the rear of the vehicle.
Claim 4
Dependent Claim
201 words
An automatic washing facility for vehicles, particularly comprising: a floor surface for supporting the vehicle; an elongated continuous guide track fixed to the floor surface surrounding and spaced from the vehicle; a mobile unit supported by the floor surface and guided by the guide track for moving around the vehicle during each washing operation; a side frame pivotally mounted on the mobile unit for pivotal movement about a substantially vertical axis; an upright side brush rotatably mounted on the side frame for engaging the rear, side, and front surfaces of the vehicle as the unit moves around the vehicle a overhead frame pivotally mounted on the mobile unit for pivotal movement about a substantially horizontal axis; a horizontal brush rotatably mounted on the overhead frame for engaging the top surfaces of the vehicle as the unit moves around the vehicle; an actuator mounted on the unit operatively connected to the overhead frame for holding the horizontal brush in an elevated position, and control means responsive to the movement of the mobile unit along the rear of the vehicle for operating the actuator to hold the horizontal brush in the elevated position as the unit moves along the rear of the vehicle.
Claim 5
Dependent Claim
127 words
An automatic washing facility as defined in claim 2 which further comprises a drive means mounted on the unit for propelling the unit around the vehicle in a selected direction and wherein the control means operates the drive means to stop and start the movement of the mobile unit adjacent one rear corner of the vehicle so that the mobile unit will first move along the rear of the unit before moving along the front of the vehicle during each washing operation and wherein the control means operates the actuator to move the horizontal brush to the elevated position when the unit stops and maintains the horizontal brush in the elevated position at the start and until the unit rounds the other rear corner of the vehicle.
