ABSTRACT:
An automatic shoe polisher includes a casing having an internal chamber for a rechargeable battery and a liquid cartridge. A pair of doors provide for access to the battery and liquid cartridge. The door for the liquid cartridge is provided with a protrusion or biasing element to maintain the position of the liquid cartridge in the casing. A motor assembly is connected to a pinion which coacts with a shaft assembly to drive the cleaning/polishing element which is mounted to the shaft by a universal coupling. The coupling permits the polishing element to be pivoted about the shaft. A spring is arranged around the shaft to bias the shaft. A valve with an inlet is arranged on the shaft to move into the chamber so that the polishing fluid is directed through the shaft to the polishing element. The apparatus can be automatically actuated upon contact of the polishing head against the surface to be polished, such as a shoe, with the speed being variable depending upon the amount of pressure exerted on the polishing head. When pressure is removed from the polishing head, the valve is displaced so that the fluid in the chamber is retained in the chamber and the rotational speed of the shaft slows.
