Oct. 25, 1949. E. H. LEDERER SPRAY NOZZLE Filed Sept. 10, 1945 INVENTOR. Eugene H Lender/5'7" il /4W1? W Patented Oct. 25, 1949 UNITED STATES PATENT OFFICE SPRAY NOZZLE Eugene H. Lederer, Brooklyn, N. Y. Application September 10, 1945, Serial No. 615,377

1 Claim. 1

This invention relates to spray nozzles and more particularly to a nozzle for forming a mist which may be produced from relatively high pressure liquid.

An object of this invention is to provide a spray nozzle which includes a pressure chamber and a plurality of jet openings radiating from the chamber, the nozzle being formed of tempered metal which will withstand relatively high pressures.

A further object of this invention is to provide a nozzle of this kind which includes a base plate of disc-shape and an apertured plate welded or otherwise fixed to the base plate and also includes a dome-shaped chamber forming member which is welded to the apertured nozzle plate, the entire assembly being of welded construction so as to provide a substantially unitary device which will withstand hard usage and can be used either in a horizontal position or any other desired position for forming a mist or fog which, when used in combat, may provide a cover for troops or the like.

To the foregoing objects, and others which may hereinafter more fully appear, the invention consists of the novel construction, combination and arrangement of parts, as will be more specifically referred to and illustrated in the accompanying drawings, but it is to be understood that changes, variations, and modifications may be resorted to which fall within the scope of the invention a claimed.

In the drawing:

Figure 1 is a detail top plan partly broken away and in section of a nozzle constructed according to an embodiment of this invention, and

Figure 2 is a sectional view taken on the line 22 of Figure 1.

Referring to the drawing, the numeral l designated generally a base plate which is of discshape and which has secured to the upper side thereof a nozzle plate, generally designated as I I. The nozzle plate II is substantially ring-shaped having a substantially smooth inner diameter 13 and the outer diameter or surface of the nozzle plate H is formed with projections or points [2, which merge with each other by means of a concave outer edge 14. The plate II is formed with a pair of jet openings l5 and It in each concave surface I4, the inner ends of the openings l6 opening through the annular inner edge 13 of the plate H. A dome-shaped top member I! is disposed on the upper side of the nozzle plate ll being secured thereto, as by welding l8 or the like.

The top member I! forms a pressure chamber 19 within which liquid under pressure is adapted so that an intake pipe 2| may be extended between theopen ends 20 of the plate II and is then formed on an angle, as indicated at 22, and welded or otherwise firmly secured to the plate H and to the dome-shaped member H. The intake nipple or pipe 2| may be of any desired length and may have coupling means at its outer end for coupling the pipe or nipple 2| to a source of liquid pressure supply. Under combat conditions the nozzle structure hereinbefore described may be used on a vessel being extended along the side of the vessel or at other suitable positions so as to form a fog in order to conceal the vessel. This device may also be used for other purposes for which a spray nozzle of this kind may be adapted.

The exact configuration illustrated is regarded as the optimum, but some of the desirable results inherent in this disclosure may be obtained by various slight modifications including some departure from the exact configuration shown, and it is therefore requested that the scope of the invention should be regarded as limited only by the terms of the claim.

What I claim is:

A spray device of the class described, comprising a disc-shaped base member, an annular fiat nozzle ring secured to the top surface of said base member and concentric therewith, the outer edge of said ring being formed with a plurality of circumferentially spaced apart concaved depressions, a dome member secured to the top surface of said ring to provide a pressure chamber, a plurality of pairs of outwardly converging horizontal nozzle bores formed through said ring, a pair of bores being provided for each of said concaved depressions and the outer ends of said pair of bores being disposed symmetrically with respect to the center of the related depression whereby the portions of said ring on the opposite sides of each of said depressions provide shields for the outer ends of said nozzle bores to prevent clogging thereof and premature admixture of the fluid ejected from the pairs of bores.
