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: A structural member is designed to define a fluid distribution conduit receiving cavity within its interior volume. An elongate extruded plastic cover snap-fits onto the member to conceal the conduit but permits nozzles and the like to extend therethrough so that fluid may be distributed from the conduit and/or serviced as necessary without removing the cover. The cover effectively supports the conduit by trapping it against a compression pad on the cavity floor.

Abstract: A rotary spray washer for heavy duty applications. Each spray device in the system comprises a rotary coupling and two sets of radially extending spray arms. Each set of arms has nozzles at the distal ends to direct water generally toward a target area but angled enough to produce a rotation-producing reaction torque. One set of arms is longer than the other whereby the shorter arms produce a reaction torque which limits the overall speed of rotation without the need for a friction brake or fluid pump brake.

Abstract: A car wash arch of inverted U-shape with a centrally mounted pendant on the overhead horizontal section, the pendant being of such size and shape as to accommodate a logo or other indicia therein. Light tubes, preferably containing LEDs extend upwardly along the vertical sections of the arch, inwardly along the horizontal section of the arch and into the pendant so as to at least partially frame and illuminate the pendant. A fluid conduit feeding a system of nozzles can be mounted to the arch and supply car wash fluids to spray nozzles inwardly from the vertical and horizontal arch sections.

Abstract: A touchless, automatic spray-type car wash system includes one or more arms delivering washing fluids wherein the arms are constructed with translucent plastic sleeves which can be illuminated from within by LEDs. Different colors for the arm or arms can be coordinated with wash process steps. Signage can be provided in the bay and can include panels which are illuminated in a sequential fashion coordinated with arm illumination colors to inform the driver as to each step being performed.

Abstract: A car wash system comprising at least one rotatable spray arm depending from an overhead carriage. The arm is equipped with a detent-type compound breakaway knuckle which permits the arm to be displaced upwardly from a lowest potential energy orientation by disengaging the detent but thereafter permitting a smooth essentially unresisted movement whereby when the force tending to cause angular displacement and the arm is removed, the arm returns to the normal operating, low potential energy position. A shaker function or a high pressure spray burst may be used to complement the gravitational resetting function as needed.

Abstract: A carwash system is disclosed wherein a spray arm dependingly mounted to an overhead longitudinally movable carriage for dispensing fluids onto the exterior surfaces of a vehicle in a wash bay unidirectionally circumnavigates the vehicle for multiple circuits while performing one or more wash functions by coordinating longitudinal and rotational movements of the arm through the selective operation of two independent motor drives. Electrical power and/or data is carried to and from electrical devices on the arm by way of a slip ring conductor which is mounted coaxially with the arm pivot on the bottom side of the carriage. The fluid supply conduit also passes concentrically through this pivot.

Abstract: A spray-type car wash system includes an overhead carriage which can move longitudinally the length of a wash bay. A pair of laterally opposed spray arms depend from the carriage. During vehicle entry into the bay, LED-based lights running down the length of each arm are caused to flash to help the driver center a vehicle between the arms. Cushioning and breakaway features protect the arms from damage. A single-arm system is also disclosed. A double-light, stationary support system is also disclosed.

Abstract: A single column or multiple column support structure for car wash installations. Each column is a hollow aluminum extrusion having a cross-section defining a smooth rounded figure such as an oval and a pair of longitudinally continuous external channels formed in opposite sides of the column to provide routes for wires and hoses. Snap in plastic covers are associated with the channels. Interior channels received fastener inserts for assembling the columns to base plates, top plates, cross-bridges and the like. Two or more columns may be assembled in parallel spaced relationship with spacers therebetween.

Abstract: A car wash brush comprising a motor and a rotatable vertically-depending brush shaft is provided with a spherical bearing which allows universal swivel movement of the brush shaft away from a normal, essentially vertical orientation. To limit the degree of swivel permitted, a plate with three angularly spaced bumpers is attached to the top of the swivel bearing and a C-shaped stop plate is arranged on a brush mount over the bumpers in fixed spaced relationship to the bearing seat such that excessive swivel motion brings one or more of the bumpers into contact with the under surface of the C-shaped plate. The bearing support structure is attached to a swing arm by means of an extra pivot which provides a breakaway function. An alarm and/or event recorder is provided to trigger an inspection in the event the breakaway function is brought into play.

Light tubes, preferably containing LEDs extend upwardly along the vertical sections of the arch, inwardly along the horizontal section of the arch and into the pendant so as to at least partially frame and illuminate the pendant. A fluid conduit feeding a system of nozzles can be mounted to the arch and supply car wash fluids to spray nozzles inwardly from the vertical and horizontal arch sections.

Abstract: A car wash dolly of the type used in connection with multi-tier car wash conveyors comprises, in mirror image arrangement, first and second pairs of stainless steel journals having external bearing surfaces and polymeric rollers mounted for rotation on said bearing surfaces wherein the journals are nitro carburized and mechanically polished prior to assembly.

Abstract: A structural member as designed to define a fluid distribution conduit receiving cavity within its interior volume. An elongate extruded plastic cover snap-fits onto the member to conceal the conduit but permits nozzles and the like to extend therethrough so that fluid may be distributed from the conduit and/or serviced as necessary without removing the cover. The cover effectively supports the conduit by trapping it against the cavity floor.

Abstract: A vehicle wash system using a light ribbon running along an adjacent wall to coach vehicle drivers as to the speed they should when transiting a multistation wash system. The light ribbon is made up of one or more rows of LED's and can be operated in any of several modes including multicolored displays as well as a “rabbit” mode. Sensors, timers, and digital processors are used to monitor vehicle location and speed and cause appropriate activation of the lighting system. An event log is maintained.

Abstract: A high velocity, multiple-jet spray nozzle for use in carwash systems. Each nozzle comprises the axial unitary combination of a base, a nozzle carrier and a face plate. An inlet and a chamber are formed in the body and axially aligned flow passages are formed in the nozzle carrier and face plate so that when the components are assembled, five parallel jets arranged in a circular pattern are defined between the chamber and the outer surface of the face plate. Stainless steel nozzle inserts are press fit into the flow passages of the nozzle carrier and are held in place by the face plate. Screws hold the assembly together. The nozzles are preferably used in multiples to define a wide stream of washing fluid which can be used to attach mud, ice and other debris on the surfaces of a vehicle as well as on wheels and undercarriage. Each nozzle has an alignment axis marked on the face plate along which the spacing between adjacent nozzle outlets is uniform.

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.
