  • Patent number: 4225997
    Abstract: A self-cleaning brush comprises a body member having a hollow interior compartment and an anterior wall provided with a number of spaced apertures through which the bristles of the brush can project. A bristle supporting member, including a brush head to which the bristles are affixed, is located within the hollow compartment and has a brush head operating member attached to its upper surface which projects through an opening in a posterior wall. The brush head operating member is movable reciprocably within the hollow compartment from a first position, in which the bristles project through registering apertures in the anterior wall, to a second position, where the bristles are fully retracted within the brush body. The retraction of the bristles through the apertures in the anterior wall allows for easy removal of hair or debris from the bristles. The brush head operating member may be locked in any desired position by means of a reciprocable lever member which extends from the brush body.
