B/LLY L VV0005 AT T 0R1VEY SPRAY GUN BACKGROUND OF THE INVENTION This invention pertains to spraying equipment for paint and chemicals, and is particularly directed to dual-spray guns for mixing a plurality of chemically interactive materials and spraying as mixed on a work surface.
Heretofore, in spray gun apparatus which mixed interacting materials as the material was sprayed, it was necessary to completely clean and wash with solvent the materials remaining after the spraying operation so that it would not clog up the unit. This entailed considerable time and cost in keeping the gun constantly washed out and much delay between each painting operation. The use of complicated solvent rinsing apparatus was also involved.
SUMMARY OF THE INVENTION One of the objects of this invention is to provide a spray gun form delivering, mixing and spraying interacting liquids which is easy and quick to maintain in cleaned-up condition and does not become clogged when the gun is not in use.
Still another object is to provide a multiple-spray gun having a flexible and disposable combined mixing chamber and nozzle.
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a side elevation of spray gun incorporating the features of this invention.
FIG. 2 is a top view, partly in section on the line 4-4 of FIG, 1.
FIG. 3 is a circuit diagram showing the supply and pumping system associated with the spray gun.
FIG. 4 is a section on the line 4-4 of FIG. 2.
DESCRIPTION OF THE PREFERRED, EMBODIMENT As an example of one embodiment of this invention, there is shown a dualor multiple-spray gun having a frame with a downwardly extending'front portion 11 in which is carried a plurality of material flow control valves 12 and 13 of conventional construction, each having an operating stem 14 actuated by a common trigger 15 associated with the usual pistol grip 16.
The material supply lines 17 and 18 connected to the respective flow control valves 12 and 13, are connected to the discharge ports of appropriate positive displacement pumps, the pump 21 having an intake line 23 connected to a supply reservoir 24 containing one kind of material while the pump 22 has an intake line 25 connected to a supply reservoir 26 having another kind of material interactive with the material in reservoir 24.
Both of the pumps 21 and 22 are simultaneously driven by any suitable means such as by an appropriate air-operated motor 27 connected through a line 28 and pressure regulator 29 to an air pressure supply line 30. A further air supply line 31 is connected to the compressed air input tube 32 terminating in the air passageway 33 on the discharge manifold block 34. Discharge tubes 35 and 36 from the respective valves 12 and 13 also connect to the material passageways 37 and 38 of the discharge manifold block 34.
The passageways 33, 37 and 38 discharge through the front face surface 39 of the discharge manifold block 34. A nozzle 40 has a suitable discharge tip 41 and an enlarged bell-shaped portion 42 demountably supported on the outer periphery 43 of the discharge manifold block 34 fonning with the front face surface 39 a mixing chamber 44 for intermixing of materials and the air from the passageways 33, 37 and 38 prior to the discharge of the mixture out through the nozzle passageway 45 and the tip 41.
With the air supply constantly issuing from the passageway 33, manipulation of the trigger 15 turns on and off and regulates the flow of the material into the mixing chamber 44 and out through the nozzle tip 41 At the conclusion of a spra operation, the nozzle 40 IS simply pulled from the penp ery 43 of the discharge manifold 34 and the face 39 thereof wiped clean and a wiping cloth or paper towel. A new clean nozzle is then reinstalled on the periphery 43 ready for the next spraying operation. Thus no intermixed materials from reservoirs 24 and 26, which would set up rapidly in any difficult-to-get-at passageways or cavities, is present in this unique arrangement.
Iclaim:
l. A spray gun for initially mixing and spraying a plurality of interacting materials comprising:
A. a discharge manifold block having a front face surface,
B. an air passageway in the manifold block discharging through the front face surface of the block,
C. a plurality of material passageways extending parallel with said air passageway in the block discharging through the front surface of the block,
said air passageway and each of said material passageways individually discharging through said front face surface of said block at spaced positions from each other,
E. a disposable nozzle having a mounting shank forming a mixing chamber with the front face surface of the block when demountably secured over the front face of the block,
F. a plurality of material supply reservoirs,
G. an individual pump connected to each supply reservoir and each discharging into one of the material passageways,
H. an air pressure supply connected into the air passageway,
and
I. a common manual control device for simultaneously regulating the flow from the pumps to the material passageways and mixing chamber.
