Retractable brush with rotatable actuating mechanism

Image Number 3 for United States Patent #4214340.

A retractable brush (10) is provided and includes a housing (12). Housing (12) includes sidewalls (18, 30), end walls (20, 22, 32, 34), a top wall (26, 38) and a bottom wall (24, 36). A bristle carrier (60) is provided and includes a plurality of bristles (50) mounted within housing (12) for slidable movement therein. The bristle carrier (60) is movable between a retracted position wherein the bristle carrier (60) and the plurality of bristles (50) are contained within housing (12) and an extended position wherein bristle carrier (60) is contained within housing (12) and the plurality of bristles (50) extend beyond the top wall (26, 38) of housing (12). The bristle carrier (60) includes an elongated slot (48). The first sidewall (18) of housing (12) includes a rotatable structure (42) for engaging the elongated slot (48), such that upon rotation of the rotatable structure (42) the bristle carrier (60) and the plurality of bristles (50) move between the retracted position and the extended position to positively retract and extend the plurality of bristles (50) from the housing (12).
