Patent ID: 7032839

Claim:
A liquid spray gun comprising a body assembly including a nozzle portion with an outlet end, said nozzle portion having a liquid passageway extending from an inlet end to an outlet end opening through the outlet end of the nozzle portion, said body assembly having a connector portion at the inlet end of said liquid passageway adapted to be connected to a connector portion on a liquid container positioned above said body assembly, said body assembly having a first air passageway extending from an inlet end to an outlet end at the outlet end of said nozzle portion, said outlet end of said first air passageway extending around said outlet end of said liquid outlet passageway and being shaped to direct air under greater than atmospheric pressure against liquid flowing out of the outlet end of the liquid outlet passageway to propel the liquid away from the outlet end of the nozzle portion while shaping the liquid into a generally conical stream about an axis, said body assembly including horns projecting past the outlet end of the nozzle on opposite sides of said axis, said body assembly having a second air passageway extending from an inlet end to outlet passageways and apertures spaced along said horns from the outlet end of the nozzle and facing opposite sides of said axis, said outlet passageways and apertures being shaped to direct air under greater than atmospheric pressure flowing through said second air passageway against opposite sides of a stream of liquid formed by air flowing through the first air passageway to reshape that stream of liquid into a wide elongate stream, said liquid spray gun further including a platform portion having through air distribution passageways including an inlet opening adapted to be connected to a supply of air under greater than atmospheric pressure, first and second air outlet openings, means for separately regulating the flow of air through said first and second air outlet openings of said air distribution passageways, and manually operated means for stopping or allowing flow of air through said outlet openings of said air distribution passageways, and said platform portion and said nozzle portion having manually operable means for releasably mounting said nozzle portion on said platform portion with said first and second air outlet openings of said air distribution passageways communicating with the inlet ends of said first and second passageways.
