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.

Dependent claims

An automatic shoe polisher, comprising:

a housing formed with an interior space;
a battery disposed at said interior space of said housing;
a container of polish disposed at said interior space of said housing;
a panel pivotally connected to said housing for permitting access to said interior space of said housing, said panel formed with a protrusion facing said interior space and for contacting said container;
a shaft disposed for reciprocating movement with respect to said housing, said shaft comprising a first end terminating at an exterior of said housing, a second end opposed to said first end and terminating at said interior space of said housing for coaction with said container, and a bore extending between said first and second ends;
a universal joint disposed on said first end of said shaft, said universal joint including a passage extending therethrough for communication with said bore of said shaft;
a polishing head removably mounted to said universal joint;
a valve disposed at said second end of said shaft for coaction with said bore and in communication with said container for providing a passage for the polish to flow from said container through said bore;
a spring mounted on said shaft between said polishing head and said housing for biasing said shaft;
a variable speed motor disposed at said interior space of said housing and connected to said battery and to said shaft for actuating said polishing head;
a switch connected to said variable speed motor and to said shaft;
and
a shoe horn pivotally connected to said housing;
wherein said shaft is movable to open said valve for said polish to flow through said bore to said polishing head, and to actuate said switch to adjust speed of said variable speed motor.
