Patent ID: 7665422

Claim:
A self cleaning rotary brush for cleaning the fur of an animal while protecting the underlying skin, the brush comprising: a housing including a proximal end with a handle and a distal end; an electric motor positioned within the housing; a primary cleaning cylinder with an outer surface and opposing ends, the opposing ends being rotatably coupled to the distal end of the housing, the primary cleaning cylinder being powered by the electric motor for rotation in a first direction, the primary cleaning cylinder including a series of primary tines extending from the outer surface, the primary tines functioning to clean the fur of the animal; an arcuate guard having opposing sides that are rotatably coupled to the opposing ends of the primary cleaning cylinder, the arcuate guard further including a shield integrally formed between the opposing sides, the shield functioning to protect the skin of the animal while the fur is being cleaned; a secondary cleaning cylinder with an outer surface and opposed ends, the opposed ends being rotatably coupled to the distal end of the housing at a position intermediate the handle and the primary cleaning cylinder, the secondary cylinder being powered by the electric motor for rotation in a second direction, the second direction being opposite to the first direction, the secondary cleaning cylinder including a series of secondary tines extending from the outer surface, the primary and secondary cylinders being positioned such that the primary and secondary tines intermesh; a collection tray with a serrated leading edge, the collection tray positioned within the housing at a location intermediate the handle and the secondary cleaning cylinder, the collection tray being positioned such that the secondary tines intermesh with the serrated leading edge, whereby rotation of the primary cylinder causes the primary tines to collect fur from the animal being cleaned and whereby the intermeshing of the primary and secondary tines causes the collected fur to be taken up by the secondary tines and whereby the intermeshing of the secondary tines with the serrated leading edge causes the collected fur to be deposited in the collection tray.
