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.
