Abstract

A brush for home use such as washing cars and patios. The brush includes a body having a plurality of dependent bristles and defining a first compartment for a receiving soap and a second compartment for receiving rinse water. The body also includes an elongate tube partially defining each of the compartments. The first compartment has an outlet for providing soapy water to the bristles while the second compartment has an outlet for providing rinse water. A spool valve is slidable back and forth in the tube with the valve having a tubular wall defining an axial bore open to the conduit and an opening extending through the wall for communicating water to either of the compartments. Seals are carried by the spool valves flanking the opening to provide watertight seals between the valve and the tube. The brush also includes a thumb switch for reciprocating the valve along a linear path among a soap position, a rinse position, and an off position where water is supplied to neither of the compartments.

Dependent claims

A washing, scrubbing and rinsing brush for home use such as washing cars and patios, said brush comprising:

a body having a plurality of dependent bristles, said body defining a first compartment for receiving soap and a second compartment for receiving rinse water, said first and second compartments being separated by a barrier wall, said body further including an elongate tube partially defining each of said compartments said first compartment having a first outlet means for providing soapy water to said bristles and said second compartment having a second outlet means for providing rinse water;
a conduit connected to said tube and adapted for connection to a garden hose;
a spool valve slidable back and forth in said tube, said valve having a substantially cylindrical wall defining an axial bore open to said conduit and an opening extending through said wall for communicating water to either of said compartments, said tube having a first aperture for providing water to said first compartment and a second aperture for providing water to said second compartment;
sealing means carried by said spool valve flanking said spool valve opening providing substantially watertight seals between said spool valve and said tube;
and
means for reciprocating said spool valve along a substantially linear path among a soap position wherein said first aperture is flanked by said sealing means so that said liquid can flow from said valve to said first compartment through said opening and said first aperture, a rinse position wherein said second aperture is flanked by said sealing means so that liquid can flow from said valve to said second compartment through said opening and said second aperture, and an off position wherein neither of said apertures is in fluid communication with said valve whereby movement of said spool valve to said soap position causes soapy water to be provided to said bristles, movement of said spool valve to said rinse position results in clear water being provided by the second outlet means, and movement of said spool valve to said off position shuts off the supply of water to said compartments.

3 more elements

A washing, scrubbing and rinsing brush adapted to be connected to a garden hose for home uses such as cleaning automobiles and patios, said brush comprising:

a body with a front end and a rear end and having a plurality of dependent tufts of bristles, said body defining a forward compartment for receiving rinse water and a rear compartment for receiving soap, said compartments being separated by a barrier wall, said body further including an elongate tube extending from said rear end and terminating in an end wall adjacent said front end and partially defining each of said compartments, said rear compartment having outlet means for providing soapy water to said bristles and inlet means for introducing soap into said rear compartment, said body further having nozzle means adjacent said front end for dispensing rinse water from said forward compartment;
a conduit extending from said rear end and connected to said tube, said conduit having a distal end for connection to a garden hose;
a spool valve slidable back and forth in said tube, said valve having a cylindrical wall defining an axial bore extending therethrough, said valve further having an opening extending through said cylindrical wall for communicating water to either of said compartments, said tube having a first aperture for providing water to said rear compartment and a second aperture for providing water to said forward compartment;
first sealing means carried by said spool valve flanking said spool valve opening providing substantially water tight seals between said valve and said tube;
and
means for reciprocating said valve along a substantially linear path between a rinse position wherein said second aperture is flanked by said sealing means and a rear soap position wherein said first aperture is flanked by said sealing means.
