Abstract: A vehicle washing system. The vehicle washing system includes a vehicle washing system component. Also, provided is an apparatus for moving the vehicle relative to vehicle washing system component. The speed of the relative motor of the vehicle is selected either by an operator automatically or may be varied to vary the vehicle throughput through the vehicle wash. A control unit is provided. The control unit senses the speed of movement of the vehicle with respect to the vehicle washing system. The control unit adjusts the vehicle washing system component for coordinating the vehicle washing system component in accordance with the speed of the vehicle.

Abstract: A car wash brush is constructed by sliding multi-layered, wheel-shaped foam plastic cartridges onto a hub with three keyways formed in the outer surfaces thereof. The cartridges use spacers interspersed with foam layers and adhesively bonded to the foam layers. The spacers have keys which fit into die hub keyways to prevent relative rotation while allowing, longitudinal sliding motion. Multiple cartridges are used to produce a brush of desired length. Old style hubs can be salvaged for use in this construction.

Abstract: An auto-laundry conveyor of three-tier design using upper, lower and intermediate track rails with a narrow slot between them. Dollies are provided in an endless loop conveyor chain and each dolly comprises a combination of a center link, a pair of reversely similar tire engaging rollers, a pair of reversely similar track engaging rollers outboard of the tire engaging rollers and a pair of reversely similar stabilizing rollers outboard of the track engaging rollers. The stabilizing rollers are effectively larger in diameter; i.e., higher than the track engaging rollers so as to prevent rolling contact between the stabilizing rollers and the track surface and to receive the tread surface of an off-center tire and keep the tread surface from interfering with rolling movement of the track engaging rollers. The conveyor is manufactured in 10-foot lengths except for the entry and exit sections which are of lengths X and Y wherein X plus Y equals 10 feet.

Abstract: A vehicle tire entry guide for transitioning vehicles into a car wash lane comprises a pair of smoothly-curved, reversely similar tire guide rails covered with plastic. Each curved guide rail comprises a curved angle iron with stanchions which can be bolted to the car wash floor and an extruded polyethylene cover which eliminates the need for moving parts and smoothly transitions into a conveyor tire guide lane. A roller grid or the like may be floor-mounted between the curved guide rails.

Abstract: An automotive wheel washer comprising a circular conduit having a diameter of approximately 12 to 20 inches and further provided with a plurality of circumferentially spaced nozzles which direct cleaning fluid and chemicals laterally of the wheel washer and toward the adjacent wheel in an inwardly converging fashion. An additional 360° center nozzle produces an outwardly diverging spray pattern which, in combination with the plurality of spaced outer nozzles, is effective to cause direct application of cleaning chemicals to all surfaces of a wheel and reduce the shadowing effect caused by intricate wheel structure patterns. Foaming is created by a porous material in a foaming chamber serving as a common inlet to all nozzles and further having a high pressure air inlet. The circular conduit may be made of plastic or stainless steel or any of a number of essentially equivalent materials.

Abstract: A drive-through vehicle wash of the type including a plurality of gantries defining a tunnel through which the vehicle passes and including a plurality of longitudinally spaced work stations along the tunnel for performing respective operations associated with the washing of the vehicle. A utility carrier is provided to facilitate delivery of the various utility lines (such as soapy water, clear water, electric power, hydraulic power, and hot air) to the various work stations. The utility carrier comprises a ladder structure positioned above the gantries and a plurality of U-shaped brackets positioned on top of the gantries. The ladder structure has a closed loop configuration overlying the gantries and includes an entry section.

Abstract: A dryer is provided for automatically drying the upper contour surface of a vehicle. The dryer includes a frame, a nozzle for directing a stream of air against the vehicle, and an arm pivotally connecting the nozzle to the frame. A drive mechanism raises and lowers the arm to enable the nozzle to follow the contour of the vehicle. The drive mechanism includes a follower affixed to the arm, a rotary drive member cooperating with the follower and a drive motor operably connected to the drive member. The nozzle and arm are lowered by the force of gravity which urges a follower into engagement with the drive member. The follower is capable of being lifted free of the drive member to enable the nozzle to rise up in the event of contact with the vehicle thereby minimizing damage thereto.

Abstract: A horizontal top brush for a vehicle laundering or finishing plant wherein a brush rotated by an hydraulic motor is mounted between the free ends of pivot arms carried by spaced vertical stanchions flanking a vehicle treatment location. Counterweight arms on the left and right sides of the wash lane have an axis of rotation which is spaced from the axis of rotation of the brush pivot arms. The counterweight arms are mechanically interconnected with the brush arms by sector gears, an arrangement which permits all of the brush and counterweight arms to lie on one side of the vertical support stanchions. The brush arms are slotted to permit the counterweight arms to pass through them. Brush position relative to the vehicle is varied as a function of brush motor reaction which in turn is a function of brush contact pressure or depth.

Abstract: An above the floor conveyor is provided for transporting a wheeled vehicle having a plurality of tires across a floor surface with a pair of the vehicle's tires oriented in a guided track. The conveyor includes a drive and idle sprocket which are spaced apart and have an endless tensile member extending in a loop thereabout to define a drive and a return flight. A series of dolly assemblies are attached to the endless conveyor tensile member in spaced apart orientation. The dolly assemblies have an elongated dolly roller for engaging a tire of a vehicle located within the guided track. The dollies are pivotable about a generally vertical dolly axis between an inactive position in which the dolly roller is pivoted rearwardly out of the guided tracks and an active position in which a dolly roller extends inwardly into the guided track. The dolly assembly has an arm extending outwardly from the pivot axis providing a follower spaced from the axis.

Abstract: A drive-through wash of a type in which a vehicle is translated forwardly along a longitudinal axis is disclosed. The wash includes a frame affixed to the floor and sized to allow the vehicle to pass therethrough. Right and left side washers are attached to the frame and are longitudinally aligned with one another for washing the right and left sides of the vehicle. A curtain washer is attached to the frame in lateral alignment with the right and left side washers and extends into the path of the vehicle. Right and left wraparound washers, each respectively having an elongated right and left booms are horizontally, pivotably attached to the frame on opposite sides, above the path of the vehicle, and extend rearwardly therefrom. Rotatable right and left wraparound wheels are supported on a pair of carriages that slide upon the elongated booms. The elongated booms pivot relative to the frame allowing the wraparound wheels to follow the contour of the vehicle passing through the wash.
