ABSTRACT:
A unique bead dispensing gun for marking pavement, the gun being actuated between open and closed positions, using fluid pressure, and the beads being delivered to and through the gun, when open, also under fluid pressure, with the gun comprising a casing or body forming in part a cylinder in which a piston operates, the lower end of the piston comprising a shut off valve to selectively prevent or permit bead discharge from a bead chamber within the gun, to which beads are supplied by a relatively large external reservoir, through a discharge opening along a novel control chute to the atmosphere, the cylinder/piston arrangement being one way (to open the gun), a return spring returning the gun to the closed position, when the fluid pressure upon the piston is removed.
