Abstract: A double boom arrangement for use in a car wash includes a first and a second boom assembly mounted side by side on a respective rotatable coupling so that a horizontal portion of the hose of each boom can rotate about a vertical axis in a generally horizontal plane with the remainder of the hose extending downwardly from the horizontal plane at an outer end of the boom. Each boom has a parking arrangement for moving the boom and the hose to a parked location extending 180 degree away from the other boom. The boom includes a first inner and a second outer boom portion with the inner and outer portions connected by a second swivel coupling parallel to the first and spaced outwardly therefrom. The inner boom portion is mounted on a bracket for pivotal movement about a horizontal axis and constrained by two horizontal springs above the pivot axis. The springs are mounted at opposite ends of a rod bent around the pivot axis where each is compressed as the first boom portion pivots downwardly.

Abstract: A garment hanger of the wire frame type includes an anti-slip member engaged over the wire rail to provide increased friction on the garment to reduce the tendency of the garment to slip off the wire rail. The anti-slip member forms an elongate generally cylindrical member along the wire rail with longitudinal ribs on the top surface and two depending fins on the underside each on a respective side of a narrow slot by which the member is engaged over the wire.

Abstract: A mounting system is provided for adjustably mounting supporting surfaces in the form of shelves and the like at various relative heights. A plurality of uprights, having indentations therein, are arranged to support respective expandable clamping assemblies thereon. The clamping assemblies include respective indentations along respective inner surfaces thereof for alignment with the indentations of the uprights such that a retainer member can be received between the respective indentations for supporting the clamping assemblies on their respective uprights. The retainer members are spring wires which are biased outwardly to expand the clamping assemblies and release the retainer members from the respective uprights. A plurality of clamping assembly housings are provided for securing the respective clamping assemblies on the uprights in an engaged position.

Abstract: A swivel coupling for high pressure fluid of the type providing an axle through which fluid can pass to a rotary connector. The swivel coupling includes first and second mechanical bearings spaced apart and mounted along the axle, wherein each mechanical bearing has an inner and an outer bearing member. The inner bearing members are attached to the axle while a mounting member attaches to the outer bearings so that the bearings provide radial and axial support between the axle and the mounting member while allowing relative rotation between them. A fluid opening on the axle between the mechanical bearings communicates with the rotary connector. The rotary connector is supported by a pair of swivel bushings wherein each swivel bushing is mounted on an opposing end of the rotary connector for locating it between the mechanical bearings. High pressure seals are fitted into upper and lower annular recesses located on the axle in respective positions above and below the fluid opening for sealing the connector.

Abstract: A wooden structural member for use as a stud in the wall of a building is formed from two strips of wood separated simply by elongate pins at right angles to the length of the strips. Each pin has pointed ends which are punctured into the wood of the strips to provide a frictional engagement therewith. After formation of the structural element, it is formed into the wall of a building and services can be threaded through the space between the strips following which insulation material is applied between each stud and the next and in between the strips thus increasing the insulation value of the wall, reducing the amount of lumber required and simplifying construction.

Abstract: A garbage bag holder of the type manufactured from a wire frame for receiving the mouth of a garbage bag which is wrapped over the wire frame into an open position to receive garbage or other material. The wire frame is symmetrical so that the bag holder is operable in an inverted position. The wire frame has legs bent relative to the bottom bars at an angle greater than 90 degrees such that flexing of the legs are required during installation of a garbage bag over the wire frame.

Abstract: A boom for the supply hose of a fluid used in a car wash is rotatable around a vertical axis in a horizontal plane. Flexibilty of the boom out of the horizontal plane is provided by a spring wire having a loop turned through more than 360.degree. partway along the length of the wire with a leveller device engaging upper edges of inner and outer portions of the wire on either side of the loop and an underside of the inner turns of the loop so as to hold down the outer portion of the wire and locate the boom in the required horizontal plane. Rotation in one embodiment is provided by a vertical portion at the inner end of the wire mounted within a suitable bearing and provided with a coil spring acting to bias the boom to a required angular orientation around the vertical portion of the wire. In a second embodiment for use with 360.degree.

Abstract: A support device for supporting longitudinal rigid members in a poured layer for example rebar within concrete comprises two V-shaped wire elements which are inverted and have parallel rails welded across the elements. Two lower rails are spaced at the end of the legs of the elements to allow the ends of the legs to be inserted into the ground. The elongate members then rest across the upper rails between two apex portions of the elements which extend upwardly above the upper rails. The rails extend out beyond the elements to provide portions which can be inserted into the ground when the device is rotated through 90.degree. to support the elongate members at a different height from the base layer. The use of a wire structure enables the concrete to be poured around the device without the formation of voids. The use of four legs inserted into a sand or similar base provides great stability.

Abstract: A security container comprises two halves which can be slid together longitudinally to close the container and locked in the longitudinally closed position. Each half comprises a channel member and an associated end cap which is of a size to cover the whole of the end of the container. Edges of the side panels of each channel member include u-shape formations to that the two halves interlock for a longitudinal movement. A money compartment is defined in the bottom of the rear half by a transverse plate parallel to the lower end cap. A drawer is mounted in the compartment and can be locked by rotating a threaded rod into engagement with a nut welded on the rear face of the rear channel member. A locking mechanism for the above container includes a protective cover including two plates covering the front face of the lock barrel with four balls between the plates allowing a key to pan between the balls into the lock but resisting a punch force to the front of the lock.

Abstract: A hose arrangement for use in a car wash of the type which provides a hose with a spray nozzle on the end and means for mounting the hose for rotation around a central pivot point including a boom which extends away from the pivot point and rotates around the pivot point. The boom is formed of a pair of flexible wires arranged on either side of the central pivot and each having coils at a position intermediate the length so as to allow the wire to flex downwardly out of the horizontal plane when the hose is pulled. The central pivot can be arranged to pivot about an axis at a small angle to the vertical whereby the boom has a lowermost position at one point in its rotation to which it tends to rotate.
