Accessory used to keep outside rear view mirrors of vehicles clear of

Abstract

An accessory, via several embodiments, is used to keep vehicle outside rear view mirrors clear of water, snow, ice, and dirt, using many available components mountable on supports of present vehicle outside rear view mirrors. Each accessory installation includes controls located inside a vehicle within convenient reach of a driver. In a preferred accessory embodiment for large trucks, a weatherproof housing is secured to standard supports, and inside is an electrical wiper motor and optionally a mirror washer liquid tank. Electrical circuit leads and liquid conduits extend respectively from the electrical wiper motor and the washer liquid tank into the cab of the truck, where an electrical switch and a liquid valve are located within reach of a driver. Also electrical leads extend from a switch in the cab to the rear of the outside rear view mirrors, where accessory heaters are mounted for use in snow and ice removal. Alternatively, the washer liquid tank and/or a liquid pump are mounted at the rear of each outside rear view mirror. The electrical wiper motor pivotally drives a wiper arm back and forth. An adjacent horizontally spaced wiper arm, not driven, is arranged in a parallelogram configuration for pantograph movements with the driven wiper arm, by having a lower cross arm pivotally secured to both wiper arms. A vertically positioned wiper blade is secured to the cross arm and translates across and back over the outside rectangular surface of the outside rear view mirror.
