ABSTRACT:
An electrostatic spray device having a gun barrel formed with a powder delivery passageway connected to a source of particulate powder material, a nozzle mounted at the forward end of the gun barrel which is formed with a discharge opening for emitting coating particles, a deflector carrying an electrode which produces an electrostatic field in the path of the coating particles emitted from the discharge opening and a pattern adjustment sleeve carried by the gun barrel which is radially outwardly spaced from the deflector and discharge opening. Both the deflector and pattern adjustment sleeve are axially movable relative to one another, and relative to the discharge opening, to vary the width of the spray pattern of coating particle emitted from the discharge opening while controlling the concentration of the electrostatic field produced by the electrode, and, accordingly, the level of ionic bombardment of the powder particles, so as to obtain an optimum electrostatic charge on the coating particles emitted from the discharge opening.
