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. rotation of the boom there is provided a locating device comprising a heart-shaped cam and a spring biased roller which acts to bias the cam and thus the rotatable hub to the cusp of the heart-shape.
