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.

Claims

1. 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.

2. A brush as set forth in claim 1 wherein said body comprises an upper body portion and a base attached to said upper body portion, said upper body portion and said conduit being integral.

3. A brush as set forth in claim 1 wherein said first outlet means comprises a plurality of holes positioned among the bristles.

4. A brush as set forth in claim 1 wherein said second outlet means comprises a nozzle positioned adjacent the front of said brush.

5. A brush as set forth in claim 1 wherein said means for reciprocating comprises a thumb switch extending above said body, said conduit serving as a handle for said brush and said thumb switch being positioned adjacent said conduit whereby said brush can be held and said thumb switch operated using only one hand.

6. A brush as set forth in claim 1 further comprising a layer of open cell sponge material covering said first outlet means, and means holding said layer over said first outlet means.

7. A brush as set forth in claim 1 wherein said body comprises an upper body portion which includes said elongate tube, said upper body portion including an elongate slot opening onto said tube, said means for reciprocating comprising a thumb switch having a thumb engagement piece and a mounting stem dependent therefrom, said stem extending through said slot.

8. A brush as set forth in claim 7 wherein said spool valve comprises a recess receiving said stem in an interference fit, said recess being defined by walls disposed inside said axial bore and isolating said recess from said bore.

9. A brush as set forth in claim 8 wherein said stem has a window and opposing ones of the walls defining said recess have protuberances which are received by said window when said stem is fully inserted into said recess.

10. A brush as set forth in claim 7 wherein said upper body portion and said thumb engagement piece include means providing a tactile indication when said spool valve is in the center position of its three positions.

11. A brush as set forth in claim 7 wherein said sealing means comprises a first O-ring and a second O-ring, said spool valve comprising flanges holding said O-rings flanking said spool valve opening.

12. A brush as set forth in claim 11 further comprising a third O-ring carried by said spool valve sealing the forward end of said spool valve from said compartments.

13. A brush as set forth in claim 11 further comprising a fourth O-ring carried by said spool valve sealing the slot from said conduit.

14. A brush as set forth in claim 11 further comprising a fifth O-ring carried by said spool valve sealing said slot from said first compartment.

15. A brush as set forth in claim 6 further comprising at least one pin extending into said first compartment from said tube, said means holding said layer comprising said pin.

16. A brush as set forth in claim 15 wherein said first aperture extends through said pin.

17. 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.

18. A brush as set forth in claim 17 further comprising a second sealing means carried by said spool valve for sealing the forward end of said valve from said second aperture, said means for reciprocating enabling movement of said valve to an off position in which neither of said apertures is in fluid communication with said valve.

19. A brush as set forth in claim 18 wherein said off position is forward of said rinse position.
