ABSTRACT:
Apparatus for applying fluid to articles. The apparatus comprises an applicator head, an internally defined cylinder interconnected with a source of fluid pressure, and a reciprocally displaceable piston disposed within the cylinder for selectively engaging articles to directly apply fluid thereto. The piston includes an output orifice at the outer extremity thereof adapted to contact an article when the piston is moved through a predetermined dispensing stroke. The orifice is in fluid flow communication with a dispensing fluid input source. In a single action embodiment the apparatus includes a return spring for resetting the piston after each dispensing operation, and in an alternative double action embodiment fluid pressure is utilized to automatically reset the piston at a preselected instant.
A closure cap on the end of the applicator head opposite the output orifice carries a stop which limits the return stroke of the piston; and the cap is held in place by a mounting bracket used to support the applicator head.
