Abstract
Abstract Roll-over car washing equipment is disclosed of the type having an inverted U-shaped frame adapted to travel over a car washing station and having air nozzles for directing drying air against the upwardly presented surfaces and also against the sides of the car in the washing station, the nozzles being supplied with air by one or more blowers mounted on the frame, with controllable means for alternatively delivering the air to the side nozzles and the top nozzle. The top nozzle is provided with mounting linkage providing for maximizing vertical movement of the nozzle while minimizing the dimension of the equipment lengthwise of the washing station.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
108 words
Roll-over type car drying equipment comprising a generally horizontally extended frame structure mounted to travel over a car washing station, an air discharge nozzle for directing air downwardly against upwardly presented surfaces of a car in said station, the nozzle having hollow hub parts at least in part of generally cylindrical form extended therefrom in opposite directions and both mounted on the frame structure with their axes generally horizontal and extended transversely of the direction of travel and providing for upward and downward pivotal movement of the nozzle, the equipment also including air supply ducts extended to the nozzle through both of the hub parts of cylindrical form.
Claim 2
Dependent Claim
108 words
Roll-over type car drying equipment comprising a generally horizontally extended frame structure mounted to travel over a car washing station, an air discharge nozzle for directing air downwardly against upwardly presented surfaces of a car in said station, the nozzle having hollow hub parts at least in part of generally cylindrical form extended therefrom in opposite directions and both mounted on the frame structure with their axes generally horizontal and extended transversely of the direction of travel and providing for upward and downward pivotal movement of the nozzle, the equipment also including air supply ducts extended to the nozzle through both of the hub parts of cylindrical form.
Claim 3
Dependent Claim
130 words
Equipment of the kind described comprising a generally horizontally extended frame structure mounted to travel over a car washing station, an air discharge nozzle having a discharge aperture toward one end for directing air downwardly against upwardly presented surfaces of a car in said station, said nozzle having a flexible air supply conduit connected with the nozzle toward the other end thereof, and means for suspending the nozzle from the frame structure comprising multiple linkage mechanism comprising a plurality of link devices each pivotally connected at one end with the frame and at its other end to the nozzle and providing for movement of the apertured end of the nozzle with respect to the frame structure in a virtually vertical plane during movement of the link mechanism between extreme positions.
Claim 4
Dependent Claim
