Abstract: An electrical brush contact apparatus for conveying electrical power from a vehicle power source to the wheels of vehicles having dual-tandem pairs of wheels includes a brush ring positioned at the juncture between the inner and outer rims of the front pair of dual-tandem vehicle wheels and the inner and outer rims of the rear pair of dual-tandem vehicle wheels. Each of the brush rings is electrically insulated from the rims with which it is associated by a flat insulating member or an insulating extrusion. Each pair of insulating extrusions and brush ring are coupled for rotation in concert with the wheels of the vehicle. Front and rear support members having idler pulleys thereon are suspended between the inner and outer pair of dual wheels and between the front and rear pair of tandem wheels. A belt, coupled between each one of the brush rings and an adjacent one of the idler pulleys, is driven by the brush ring.

Abstract: The invention relates to a lighting system for vehicle wheels and comprises a disk assembly which facilitates the electrical attachment of a rotating light with a stationary electrical power source of a vehicle. Further, the invention includes a mounting system for mounting a disk to the lugs of the vehicle on the inside of the wheel. The disk comprises first and second coaxially mounted electrically conductive rings which remain in continuous electrical contact when rotated relative to each other. The mounting system includes an electrically conductive portion and an insulator portion which electrically separates the mounting assembly from the first and second rings; the electrically conductive portion of the mounting means being used to electrically ground the rotating lights.
