A coupler (5) for connecting a variety of brushes (101) to handles (3) commonly used in the swimming pool industry comprises a generally cylindrical, hollow handle coupling end (25) and a tapered, threaded brush coupling end (23) at opposite ends of a body having a valve assembly (39) therein. The valve assembly (39) includes a generally cylindrical valve member (41) cooperable within a cavity (37) within the coupler body. As the valve member (41) is rotated by an external actuator (43), a duct (57), within the valve member (41) comes into and out of various degrees of alignment with a duct (38) in the body, the duct (38) being continuous from the handle coupling end (25) of the coupler to the brush coupling end (23). A dispensing tube (89) proximate the brush coupling end (23) directs fluid externally of the coupler (5) onto bristles (9) of the brush (101). The coupler (5) may also be used to couple handles (3) without reservoirs to brushes (101) having either threaded or unthreaded handle-receiving holes. In cases such as these in which no dispensing is required, the valve assembly (39) may readily be removed from the coupler (5). |
