  • Patent number: 4830279
    Abstract: A flat spray nozzle for a powder spray gun comprises a nozzle body formed with an axial powder flow passageway, a pair of spaced powder discharge slots intersecting the powder flow passageway and a bore located between the powder discharge slots. The bore in the nozzle body receives an electrode which extends forwardly of the spray nozzle, between the powder discharge slots for electrostatically charging particulate powder material emitted from the powder discharge slots without disrupting the spray pattern of particulate powder material.

  • Patent number: 4815666
    Abstract: A powder spray gun for use in spraying particulate powder material of different colors is constructed of a number of individual parts which are quickly and easily disassembled from one another so that each part which comes into contact with particulate powder material can be individually cleaned in changing over from one powder to another. The powder spray gun comprises a mounting block which carries a rearward barrel member and a powder inlet tube, a forward barrel member connected to the rearward barrel member, a nozzle and pattern adjustment sleeve both carried on the forward barrel member and an electrostatic cable assembly received within a barrel liner which extend axially along the length of the spray gun. All but one of the connections between these parts are made by O-rings which frictionally engage facing surfaces of the parts so that they are easily pulled apart, cleaned by a jet of air or the like and then reassembled in preparation for spraying another color of particulate powder material.
