a housing of a generally flat circular configuration having a top surface, a bottom surface, and depending cylindrical side wall surface forming

a brush receiving compartment of a circular diameter formed integrally in said housing member substantially centrally thereof and opening out of said bottom surface,

an opening adapted to receive said flexible cord therethrough, said opening extending through said housing member side wall surfaces normal to the axis of said brush compartment and interconnecting exterior of said housing member to the interior of said brush receiving compartment;

a threaded cylindrical recess formed integrally in said housing member concentric with the axis of said brush receiving compartment and opening out of said brush receiving compartment top surface; and

means engaging said threaded cylindrical recess to rotatively support said brush thereon.

3. A scrubbing brush as set forth in claim 2 wherein said valve means and said means interconnecting said handle member to said head member comprises:

an elongated generally cylindrically shaped body member formed integrally with said handle member housing portion and extending radially outwardly and upwardly therefrom and terminating at a back end spaced outwardly from said handle member housing portion;

a bore of a circular diameter formed integrally in said outermost end of said body member and opening outwardly therefrom;

an elongated passageway extending from said bore through said body member and into said head member housing where it opens into said brush receiving compartment through the top surface thereof;

a slot formed integrally in a side wall of said body member extending parallel to said passageway and placing said passageway in communication with exterior of said body member;

a knob of a width to be guided by opposite edges of said slot and of a length less than said slot being slidably received in said slot for longitudinal movement therealong between opposite ends of said slot;

a truncated conically shaped piston member having a truncated forward apex end, a base end, and conical side walls, the piston slidably received in said passageway between a position opening said passageway and a position closing said passageway;

a threaded aperture disposed in a sidewall of the piston adjacent said slot; and

a threaded bolt adapted to pass through an aperture in said knob and be threadedly received in said threaded aperture of said piston for attaching said knob to said piston for controlling the movement of said piston by said knob exteriorly of said body member between said open and said closed positions.

4. A scrubbing brush as set forth in claim 3 wherein said handle member comprises:

an elongated hollow cylindrical body member having an open front end, an open back end, cylindrical side walls, and a cylindrical compartment extending completely therethrough;

a reduced diameter flange member formed integrally with said front end and projecting axially outwardly therefrom and having an exterior diameter substantially equal to the interior diameter of said body member bore and adapted to be telescopically received in said bore with said front end of said handle member in abutting relationship with said back end of said handle member;

screw threads disposed about the interior side walls of said compartment adjacent said back end thereof; and

a cap having a body portion with screw threads disposed about the periphery thereof and adapted to be threadedly received on said threaded portion of said compartment to sealingly close said compartment while permitting access thereto for the insertion of liquid soap thereinto.

5. A scrubbing brush as set forth in claim 4 wherein said brush member comprises:

a flat disc shaped base member having a flat top surface and a flat bottom surface;

a cylindrical collar member affixed to the periphery of said base member and projecting upwardly from the top surface thereof to define with said top surface a brush chamber;

an aperture extending through the axis of said base member;

a cylindrical boss member formed integrally with said top surface of said base member concentric with said aperture and extending upwardly therefrom a distance equal to the distance of projection of said collar member and having an aperture extending therethrough in alignment with said base member aperture;

an annular groove disposed about said collar member and adapted to receive said cord therein, said groove disposed in registration with said side wall opening of said housing member when said brush is received in said brush compartment;

a pin extending through said annular groove for having one end of said cord affixed thereto;

a multiplicity of flexible brush forming bristles each having one end affixed to the bottom surface of said base member with said bristles projecting downwardly and outwardly therefrom;

a multiplicity of openings disposed completely about said base member in said brush chamber and extending through said base member to place said top surface of said base member in communication with said bristles; and

said collar member being of a diameter less than the diameter of said housing member brush receiving compartment so as to be received concentrically therein for rotation relative thereto.

6. A scrubbing brush as set forth in claim 5 wherein said means rotatively mounting said brush member in said housing member comprises an elongated bolt having a threaded shank and an enlarged head portion, the shank being of a diameter to be received through said axially extending aperture of said brush base member and to be threadedly received in said threaded recess of said housing member, said bolt head member being of a diameter larger than said apertures to engage said base member bottom surface to rotatively support said brush member in said brush receiving compartment.
