ABSTRACT:
A utility brush, usable in car or window washing, includes a hollow, cylindrical handle which communicates through a passageway to a brush head, and has been improved whereby a piston is manually operated within the cylinder, by a handle extending through the side wall of the cylinder, the movement of this handle along a slot in the cylinder definingthe stroke of the piston; a collapsible diaphragm-type valve at the passageway connection end of the cylinder opens to allow a large flow of fluid on the piston vacuum stroke and is otherwise closed to divert fluid flow through small by-pass ports leading to the brush head passageway.
