Abstract: A reversible and quick change nozzle holding tip assembly for spray guns is provided with a base member for attachment to the outlet end of the spray gun which rotatably mounts an adapter piece. A gasket member extends from the outlet end of the spray gun through the base member and adapter piece into contact with a nozzle mount holding a nozzle in a recess in the adapter piece. The nozzle mount is contained in a nozzle mount holder having a bridge portion projecting radially outwardly of the adapter and terminating in a second nozzle mount containing a second nozzle. The nozzle mount holder is both reversible to invert a given nozzle and invertible to insert the second nozzle. A clamping or cover nut includes a quick lock thread mesh with the adapter piece to clamp the nozzle mount in position in the adapter piece in engagement with the gasket.

Abstract: A powder spray chamber balances the downward forces of gravity on the coating particles with upward exhaust forces to suspend the coating materials adjacent the work piece for a longer period of time than would otherwise be possible.

Abstract: A diode-capacitor multiplier circuit usable with an electro-static spray gun has two different values of capacitors. By changing the ratio of the number of larger size capacitors to the number of smaller size capacitors, the amount of energy stored in the multiplier circuit may be increased or decreased changing the probability of ignition, and also the quality of the coating received by the subject article.

Abstract: An electrostatic hand-held spray gun with a body consisting of a barrel affixed at a selected angle to a handle. The barrel has a boring which terminates at an atomizer. The handle contains a boring which at a lower end terminates in a hose connection and at an upper end at a control valve. A second end of the barrel boring also terminates at the valve. The control valve is operable by a trigger rotatably affixed to the handle and controls the flow of color material through the boring in the barrel. A spray electrode is located adjacent the atomizer. A tubular trigger guard structure is located near the second end of the barrel in front of the trigger and is oriented at a selected angle with respect to the barrel. A high voltage cascade multiplier module and a step-up transformer module are removably mounted within the trigger guard. A low voltage cable brought into a lower end of the trigger guard provides power to drive the step-up transformer.

Abstract: An atomizer head for use with a spray gun has a centrally located paint spray orifice with an essentially elliptical cross-section and a pair of compressed air output orifices offset from the paint spray orifice. The output air forms a screen, with an elliptical cross-section, that prevents the paint spray from breaking up.
