ABSTRACT:
A brush with automatic water shut-off is disclosed. The brush includes a handle portion pivotally connected to a body portion with a valve chamber intermediate to control water flow through the brush. A flutter valve is loosely positioned within the valve chamber and is continuously biased toward the valve chamber seat by the water pressure. An operating rod is movable within the body portion and extends past the plane of the seat. When the brush is not in use, water pressure forces the flutter valve toward the seat and contact between the flutter valve and the operating rod causes the body portion and handle portion to be pivotally offset with no water flowing. When the brush bristles contact the surface to be cleaned, the body and brush portions are urged into axial alignment about the pivot whereby the operating rod will force the flutter valve off of its seat, thereby automatically causing water flow through the brush. In one embodiment, axial movement of the operating rod is controlled by an external lever to vary the position of the operating rod relative to the seat to thereby adjust the volume of flow.
