Abstract: A tire dressing applicator comprises a support and one or more foam plastic elements mounted on the support so as to contact a tire sidewall and transfer dressing onto the tire sidewall. A distribution system drips or drizzles dressing onto the element(s) after which it is spread over and into the element(s) surface. The elements can be toroidal or rectangular and have anti-distortion pins embedded therein.

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 car wash system for large vehicles, such as trucks and busses, in which the arrival of a vehicle initiates a process of directing hot water from a supply tank through a relatively long supply line to a spray system. Water standing in the supply line is prevented for a time from going to the spray nozzles and, instead, is directed back to the source. This allows the temperature in the line to reach a predetermined desired value before washing is started. Water is recirculated at a faster rater than it is dispensed once the desired temperature has been reached.

Abstract: A tire dressing applicator assembly comprises a linearly arranged series of toroidally-shaped plastic rollers having one or more beveled edges and reinforced for shape retaining purposes by pins which extend axially through the bodies of the elements outboard of a center opening which is adapted to receive a support shaft.

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 molded plastic mixing station housing for mixing water and chemical for car wash applications comprises a generally right hexahedron having a deep top recess which visually divides the housing into parallel spaced apart towers. A cylindrical mixing reservoir is recessed into the front of the housing such that a Hyrominder can be mounted in the top recess to overlie the open top of the mixing reservoir. A stand-off welt wraps around the entire housing just below the vertical center line to provide a stand-off feature for both wall mounting as well as the mounting of a control panel on one of the side surfaces of the housing. Mounting bracket slots are provided in the four upper corners of the housing for both wall mounting and control panel mounting. A deep recess runs down the back side to provide space for an overflow tube. The housing is preferably rotocast from high density polyethylene and may be color coded to match with the supply for a particular chemical.

Abstract: A tire dressing applicator comprises a support shaft mounted between the ends of a bracket and a plurality of tire dressing applicator foam rollers mounted on the shaft for rotation both with the shaft and in unison with one another and, as necessary when contacting a tire sidewall, relative to the shalt itself to prevent and/or reduce unnecessary roller wear. A drizzle-type system of dressing dispenser pipes drizzles dressing onto the outside surfaces of the rollers and a felt flap spreads the dressing and prevents waste which is characteristic of spray type systems. A quick-release mechanism associated with one end of the roller shaft where it is connected to the bracket permits the shaft to be released for the purpose of replacing worn rollers. Individual rollers are constructed using hard plastic cages which are adhesively bonded in toroidal foam volumes to prevent lateral scrunching or distortion of rollers during use.

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 vehicle washing system associated with a bay in which a vehicle is parked during the washing operation is equipped with a centering target which can be selectively deployed upon entry of a vehicle to assist the driver in placing the vehicle on the longitudinal centerline of the effective washing area in the bay. The target may be provided by a vertically-depending spray arm having internal LEDs which are illuminated in a flashing effect during vehicle entry and in constant colors during the washing program. Several alternative target arrangements are described.

Abstract: A vehicle wheel washer comprising a pair of spaced-apart, mirror image, depending spray arms with spray heads mounted at the lower ends and directed inwardly toward the wheels of a vehicle which passes between the spray heads. The spray arms are mounted pendulum-type from an overhead pivotal support to move in unison between angular displacement positions thereby to follow the wheels of the vehicle being washed for a considerable linear distance to increase the effectiveness of the wheel cleaning operation. A bi-directional hydraulic actuator controls the positions of the pendulum arms in combination with gravitational force.

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.

Abstract: A combination automotive floor mat cleaning and fragrance applying system comprising an elongate conveyor, an infeed station made up of opposed rollers, a wet scrubber station, a hot air drying station downstream of the wet scrubber station and a fragrance applying station for applying one of several selectable fragrances to the floor mats after they are cleaned and dried.

Abstract: A tire dressing applicator station for use in car wash installations wherein the applicators are tolerant of large degrees of vehicle misalignment, misorientation and entry contact shock. In each applicator structure, an additional pivot or “knuckle” is placed in one of two support arms which are pivotally connected between floor anchors and an elongate mounting carriage to which the dressing applicator elements are attached. Flared tire guides are located on the entry ends of the applicator structures to make contact with the tires of approaching vehicles whereby one or both of the two applicator structures is/are reoriented as necessary to accommodate the actual location of the vehicle, whether it be on the intended path of travel or off to one side and/or angularly misoriented relative to die intended path of vehicle travel.
