SPRAYING DEVICE.
Application med April s, 1925. Serin No. 20,323.
The invention relates to improvements in pneumatic sprayers, particularly paint sprayers such as the one disclosed in my copending application Serial No. 20,322, filing date April 3,1925.
The primary object of the invention is to provide a novel spraying 'device adapted to apply paints of a multiplicity of colors to surfaces such as those of ceramic tile to obtain a mottled color effect.
A more specific object resides in the provision of a spraying device of the above charucter of novel means for mixing the differently colored paints in the spray head.
A further object is to provide a spraying device which can be adapted to either project the features of my invention. Fig. 2 is a sectional view thereof taken substantially along line 2-2 o Fig. 1.
Fig. 3 is a view taken along line 3-3 of Fig. 1 of the front plate forming part of the spray head.
Fig. 4 1s a front end view of the spraying device.

Fig. 6 is a rear view takenalong line 6 6 of ig11 of the casing forming part of the spray Fig. 7 is a perspective view of the mixing cone. v
Fig. 8 is a fragmentary sectional view of the means for controlling the supply of paint to the spray head.
While the invention is susceptible of various modifications and alternative constructions, I have shown in the drawings and will herein describe in detail the preferred em- .bodiment, but it is to be understood that I do not thereby intend to limit the invention to the specific form disclosed, but aim in the accompanying drawings to cove-r all modilications and alternative constructions falling withm the spirit and scope of the invention.
Referring to the exemplary embodiment of the drawings, the spraying device consists of a flat base pla-te 10 substantially rectangular 55 1n shape and on the front end of which the spray head 11 is mounted. The spray head consists of a casing 12 which is preferably rectangular and box shape in construction, and which extends across and is longitudinally secured to the base plate 10 by bolts 13. The interior of the casing 12 constitutes a large cylindrical chamber 14, the lower side of which opens through a hole 15 in the lower wall of the casing into a port 16 in a fitting 17 65 extending through the 'base plate 10. Formed in the front- Wall of the casing 12 and adapted to discharge pressure fluid such as compressed air in-small streams from the chamber 14 are a plurality ofvrestricted air ports or orifices 18. v'l0 These ports are. arranged in a group at equal distances about a central conical opening 19. The rear-wall of the casing 12 is formed with a large conical opening 20 in alinement with the opening 19. h
Extending through the chamber 14 and having its opposite ends fit-ting tightly into the openings 19 and 2O and its front and rear surfaces iush with the front and rear .outer surfaces of the casing 12 is a conical block'21 hav- 80 ing a plurality of small longitudinal passages 22 extending therethrough. In the present instance, four passages 22 are provided which diverge rearwardly so that the front ends of said passages are closely spaced together and the rear ends of said passages are spaced relatively far apart.
Secured to the rear wall of the casing 12 is a plate. 28 having tapped holes 24 spaced apart to open next to the rear ends of the passages 22. A plurality of paint conduits 25, one for each passage 22 and opening thereto, are threaded into the holes 24, and are provided with hose attaching nipples 26.
A front plate 27 is secured to the base plate 05 10 and fits tightly against the front of the casing 12. The front plate is formed with a cylindrical chamber 28 in its inner surface,
and is provided with a paint nozzle 29 having a restricted jet passage 30 opening centrally )0o therethrough. A plurality ofsmall ports or orifices 31;'are; formedI in the `front .wall of the chamber` 2,8about the jet passage 30. The inner end oftheenozzlel 29 is provided with a 1 peripheral.; flange {i2-.which fits tightly over the, ports or orifices; 18 Y, in; thefront wall of theingfland whichserves to seal Said orifices.y against; the flow,l of pressure fluid thenethrough. ,Thev innerend of the jet passagey is flared toiprovide an enlargement communicatingfwith.allofthe passages 22 extending through ik the frustrated cone 21.

A valve member 36 having a diametrical; passage 37 and an; operating lever 38 is rotatablymounted in thetitting 17 ybej 0tween the passages 16:and 3'4, and is'adapted to :out oi` the chamber 28. y Y.

When the front plate 27 is secured in ,place the air ports 18 are closed, and the jets ofy aint from the passages 22are commigled in the jet passage 30 in the nozzle 29, but are not mixed suiliciently to form a homogeneous mixture. and compressed air is discharged through the ports 31 to create a suction' at the outer end of the jet passage 3() to induce the flow of paint. 1 The supply of paint can be cut off whenLdesired by rotating the clamping bar 48 into a vertical position ,thereby collapsing the hose The valve member 36 is opened,-
