- a housing having a head, a hollow head chamber contained within said head and a handle attached to said head, said handle including an open-topped container receiving section;
a first bristle having a passageway passing therethrough attached to said head, said passageway including an inlet portion and an outlet portion, said inlet portion of said passageway intersecting said head chamber;
a shaft received by said head chamber having a longitudinal axis passing therethrough;
a cam attached to said shaft and received in said head chamber and positioned adjacent to said inlet portion of said bristle passageway;
an open-topped container for holding a fluid received by said handle in said container receiving section, said container having a flexible portion, whereby said flexible portion of said container exposed by said open-topped container receiving section, wherein said shaft is positioned externally of said open-topped container;
means for coupling said container to said head chamber so that said container is in fluid communication with said head chamber; and
means for rotating said shaft about the longitudinal axis and adjusting the cam position with respect to said inlet portion of said first bristle passageway positioned externally of said open-topped container, so that when said cam is in a first position, said cam blocks [and]said inlet portion of said passageway of said first bristle and when said cam is in a second position, said cam is spaced apart from said inlet portion of said first bristle passageway so that said container, said head chamber and said bristle passageway are in fluid communication and when said exposed flesible portion of said container is depressed, a fluid can be forced from said container through said chamber and said first bristle passageway so that the fluid can exit said outlet portion of said passageway.

Abstract
A brush dispenser designed to emit a controlled amount of liquid through and out the ends of or other opening in the middle set of bristles. Selection of the number of bristles being used as conductors can be achieved by adjusting the shaft to which cams are connected. Control of the amount of liquid flowing through the selected bristles can also be achieved by adjustment of the shaft to which the cams are connected. The liquid is contained in a removable container in the handle of the brush. Finger pressure on the removable container activates the liquid flow. A cutout in the handle allows the fingers to contact the liquid-holding container.
