  • Patent number: 5711485
    Abstract: The invention is directed to an improved pneumatic valve for use in paint spray guns of the type having a pneumatic trigger operating mode. When actuated by a trigger, the valve vents a pressurized chamber in the spray gun, causing a piston to move to open air and fluid valves for initiate spraying. The pneumatic valve is in the form of a snap in module which is easily replaced without the need to remove the spray gun from the spray booth and without the need to replace a number of small parts. A small return spring and the pressurized air urge a valve poppet to a closed position. When the trigger is operated, the poppet is unseated to vent the pressurized chamber in the spray gun. The flow of air through the valve during painting prevents dirt and paint overspray from accumulating on the valve.

  • Patent number: 5395054
    Abstract: Light weight fluid and compressed air supply hoses are attached to a hand held paint spray gun. The heavier air hose is attached through a swivel fitting to permit the gun to rotate relative to the air hose. One or more generally e-shaped clips secured along the air hose retain the smaller fluid hose next to the air hose, while permitting the fluid hose to move in an axial direction relative to the air hose without kinking as the spray gun is manipulated during use. The light weight fluid hose is attached through fittings to a heavier fluid supply hose. An S-shaped clip supports the fluid hose fitting from the air hose to relieve stress on the end of the light weight fluid hose.

  • Patent number: 5332156
    Abstract: A removable cover for a paint spray gun and similar tools. The cover is formed into two halves which enclose opposite sides of the gun. A tab on the front of each cover half is retained in a notch in the gun. Rear ends of the cover halves are releasable secured together by a first spring clip positioned in aligned grooves in the cover halves. Ends of the cover halves which extend over a gun handle are releasable secured together by a second spring clip positioned in aligned grooves in the cover halves.

  • Patent number: 5289974
    Abstract: An improved hand held spray gun. The spray gun includes at least one manual trigger which when squeezed moves a valve needle to initiate fluid flow. A knob is provided to adjust the maximum fluid flow when the trigger is squeezed. When the trigger is released, a compression spring returns the valve needle to its closed position. An over travel spring is compressed only if an excessive force is applied to the trigger to prevent damage to the spray gun. The over travel spring is stronger than the valve needle return spring so that it compresses only after the spray gun is fully on. If the maximum fluid flow adjustment knob is turned too far, compressed air is vented through the knob as a tactile warning to the spray gun operator to not turn the knob further. The vented air also may whistle to provide an audible warning that the knob should not be turned further.

  • Patent number: 5137434
    Abstract: An improved oilless air compressor which is driven by a high speed universal motor. A sprocket and belt driven pulley are arranged to reduce the compressor speed. A motor driven fan and baffles are provided to direct cooling air in predetermined sequences over the motor and compressor components to increase the operating life of the compressor components, to optimize the compressor efficiency and to reduce the temperature of the compressed air output. The compressor is provided with improved intake and exhaust valves.

  • Patent number: 5054740
    Abstract: An improved air compressor tank mount. Grooves are formed along opposite sides of the bottom of the air compressor housing. Two brackets are welded to the top of the air tank. Each bracket has two upwardly and inwardly facing hooked ends which are spaced to engage the air compressor housing grooves. The air compressor slides onto the hooked bracket ends until one or more bracket end abuts a flange and the compressor may be retained on the brackets by a single screw.

  • Patent number: 4760962
    Abstract: A paint cup and lid assembly for a spray gun of the type operated from a source of compressed air. A shroud connects the paint cup to the spray gun. The shroud is indexed between a first position which provides for pressure assisted paint feed and a second position which provides for suction paint feed.

  • Patent number: 4712353
    Abstract: A hydraulic shock absorber is formed as a sealed assembly and subsequently, at a desired time, an opening is non-contaminantly pierced in the outer shell and the shock absorber is pressurized by passing a pressurized fluid through the opening and the opening is then non-contaminantly sealed with a metal ball by welding to make the hydraulic shock absorber permanently gas pressurized. The shock absorber assembly, the method of making it and the apparatus for making it are disclosed in this specification.
