  • Patent number: 8465594
    Abstract: Motor vehicle jumper cables comprising an integral wire brush mounted on an interior portion of the clamp assemblies is herein disclosed. The jumper cables with the wire brush are to be motioned to remove battery terminal corrosion, thereby providing for a better electrical connection. The device resembles a standard pair of jumper cables used to aid in jump-starting a motor vehicle with a dead battery and comprises a small wire brush located inside of each jaw area. The bristles are made of conductive steel or copper of a sufficient stiffness to clean any corrosion from the battery terminals as the clamps are being installed. Due to the conductive nature of the bristles, current will flow through the bristles as well as the clamp body, thus improving charging and starting ability.

In this invention, the battery and the cables are incorporated into one unit which includes the battery, the cables and protective holsters (housing) to lodge the cables. The holsters are an integral part of the unit and swivel at 90.degree. (degrees) to permit easy access. In this way, everything can be carried in one hand. Also, because the unit can be easily placed close to the engine, the cables can be much shorter than regular booster cables. It is easier to use since there are only two connections to make instead of four. Finally, the holsters, which house the booster clips protect the user from short circuits.
