Abstract
A fountain brush having a bristle carrier and a set of bristles thereon, a handle attached to the bristle carrier and forming a reservoir for a liquid or pasty medium, and an actuating device, attached to the end of the bristle carrier, remote from the bristles and comprising an actuating press-member, which is attachable to the inner wall of the handle via compressible bellows means is described. A channel is provided leading through the bristle carrier from the reservoir to an outlet orifice between the bristles, and an obturating member which either closes the orifice or clears it for the discharge of the medium therefrom. The obturating member is devised as a slide valve body guided in the interior of the channel and travels sealingly along the channel wall; the compressible bellows means is devised as a return spring member and is sealingly connected to the actuating press-member only after the medium has been filled into the reservoir; finally a connecting member, extending through the interior of the reservoir, is provided which rigidly connects the press-member and the slide valve body to one another and is of such length that, when the bellows means are relaxed, the slide valve body seals the outlet orifice, while it clears the orifice when the bellows means are compressed.
