Description

W. F. STEINEN SPRAY NOZZLE May 23, 1961 Filed July 18, 1958 INV N R. MlJJ IM STE/IVE nrroy vo' United States Patent SPRAY NOZZLE William F. Steinen, Short Hills, NJ. (43 Bruen St., Newark 5, NJ.)

Filed July 18, 1958, Ser. No. 749,405 2 Claims. 01. 239-597 It is among the objects of the present invention to pro-.

vide a novel, readily formed spray nozzle which will be reliable in operation to produce a predetermined spray pattern for various types of liquid sprayvapplications,

particularly in industrial utilizaton.

Another object is to provide a readily machined spray nozzle device which may be utilized to produce a pre-- determined spray pattern of great accuracy with varying types of aqueous solutions, suspensions or dispersions.

Still further objects and advantages will appear in the more detailed description set forth below, it being understood, however, that this more detailed description is given by way of illustration and explanation only and not by way of limitation, since various changes therein may be made by those skilled in the art without departing from the scope and spirit of the;present invention.

In accomplishing the above objects according to one preferred embodiment of the present invention it has been found most satisfactory to form a relatively squat, short body of hexagonal stainless steel, brass, copper, hard rubber lead alloys (such as Uscolite) or aluminum stock which will have the hexagon shape cut oif abruptly at the mounting end with a tapered pipe thread and cut off gradually at the exit end and with the device then terminating in a cylindrical knob portion having a bevel edge.

Interiorly of the device there is a centrally located elongated cylindrical chamber or passageway having a diameter of about one-fourth to one-half of the maximum thickness of the brass from side to side of the hexagon shape which domes adjacent to the outlet end beyond the area of the gradual hexagon cutofi and terminates at the end of the cylindrical knob portion but short of the bevel.

The interior dome is traversed by a V-shape slot which cuts into the top of the dome, forming a double arcuate narrow opening.

The slot is designed to reach its maximum depth at the center or longitudinal axis of the nozzle extending below the cylindrical top portion and intercepting the gradual oblique cutoif of the hexagon portion at the outlet of the nozzle structure.

In the preferred form the V-slot has curved side portions which attain maximum divergence from one another as they approach the center axis of the nozzle and the base of the V is at all times below the cylindrical top portion of the nozzle.

With the foregoing and other objects in view, the invention consists of the novel construction, combination and arrangement of parts as hereinafter more specifically described and illustrated in the accompanying drawings, wherein is shown an embodiment of the invention, but it is to be understood that changes, variations and modifications can be resorted to which fall within the scope of the claims hereunto appended.

In the drawings wherein like reference characters denote corresponding parts throughout the several views:

Figure 1 is a side elevational view of the nozzle device according to the present invention showing the mounting therefor in dot and dash lines. I

Fig. 2 is a top plan view of the nozzle of Fig. 1.

Fig. 3 is a side vertical sectional view of the top of the.

- nozzle upon the line 3-3 of Fig. 2.

Fig. 4 is a side vertical sectional view of the top of the nozzle upon the line 44 of Fig. 2.

Referring to the nozzle of Figs. 1 to 4 there is shown a hexagon body \A at the upper open end of which is a. V-shaped slot with downwardly converging bottom edge portions C and an upper and outwardly diverging side wall section B, which side wall portions B diverge from the center of the nozzle but converge toward the side edges of the nozzle as shown in Fig. 2.

The lower end of the hexagon is cut ofi? at 10 to form a downwardly tapered pipe threaded portion which terminates in the bevel 11.. The tapered portion 10 is; screwedinto the mounting shown in dot and dash lines:

. in Fig. 1.

gon body portion 14.

At the other side of the bodyportion 14 is a gradual 10-oblique bevel portion 15 which terminates just as:

the'hexagonal sides disappear as shown in Fig. 1 in thecylindrical portion 18, the upper edge of which is beveledi at 19.

Interiorly and extending centrally on thelongitudinal'. axis is the central cylindrical chamber or bore 16 which terminates-in the parabolic dome portion 17 in the cylindrical head member 18.

The top of the dome 17 terminates below the upper flat: face of the top of the nozzle.

Extending transversely through the top of the nozzlefrom side to side and above the hexagon sides 14 is the. V-shaped slot.

The lower edges of this slot as indicated at C converge..- downwardly until they meet the bore 16 below or at the: beginning of the parabolic dome 17. The side walls B: of the slot are curved in such a way that they diverges upwardly and sidewardly from the central axis and con-- verge toward the side edges of the nozzle.

It will be noted by reference to Fig. 2 that the slot is: aligned with corners of the hexagon extending towards; but terminating short of the diametrically opposite coir ners. The sidewalls B (see Fig. 4) of the V-slot terminate and appear as notches 25 (see Fig. 2) in the beveled surface 15 (see Fig. 4) while the upper edges of the V-slot 21 (see Fig. 2) are arcuate on the upper flat surface 20 (Fig. 3) of the nozzle and reach a maximum separation at 22 (see Fig. 3) coincident with the longitudinal center axis of the device.

Since the sidewalls B (Fig. 4) of the V-slot always terminate in the beveled surface 15 (Fig. 4) the edges of the notches 25 (Fig. 2) are produced inherently sharp and practically burr-free and it is thereby possible to produce a spray stream that leaves the ends of the notches 25 (Fig. 2) clean and without the usual irregularities and lack of spray definition which extend themselves into the outermost ends of the projected spray pattern.

The diagonal position of the V-slot as well as its remote location and extent relative to the hexagonal wrenching area, affords maximum protection from damage during assembly and/or disassembly of the device.

It will be noted that the slot breaks through in the bevel portion.

It will be noted at the break through in Fig. 2 that the width of the transverse slot is about the same as the transverse width of the opening at 26 into the bore 16.

The upper edges of the .V-slot 21 (Fig. 2 converge radially. at either end until they intercept the-bevel: 19 (Fig. 4) and the cylindrical portion 18. I

The opening into the parabolic dome 17'as indicated at 26 in Fig. 2 has two arcuate portions which meet at points attopposite sides in the proximity of the full "cylindrical width of the bore.16 as shown in Fig. 2 and diverge apart as they approach the central axis or longitudinal axis of the nozzle. By this specified arrangement and proportionment of the nozzle a V-spray of great accuracy in predetermined area of coverage may be produced even at varying pressures through the inlet bore l6. V

The character of the central passage 16 with the para bolic dome'17 and the sidewalls B and the bottom of the V-slot C greatly influence the control of the spray dis tribution, however the sharp clean definition of spray character at the outer ends of the V-s'haped spray is attrib uted to'the fact that the spray. stream leaves the ends of.

the notches 25 (Fig. 2), cleanly because the V-slotbreaks through in bevel 15 therebyeliminating the usual irregularities of the spray pattern at the outermost ends of the projected spray stream in similar devices.

The purpose of the nozzle of the present invention is.

in the cylindrical element 18. The relief notches indicated at the end of the V-slotin Fig. 2, at 25, assure the elongated rectangular shape of the pattern.

While there has been herein described a preferred form of the invention, it should be understood that the same may be altered in details and ,in relative arrangement of parts within the scope of the appended claims.

Having now particularly described and ascertained the nature of the invention and in what manner the same is to be performed, whatis claimed is:

l. A spray nozzle having a hexagonal body, having a central cylindrical bore extending therethrough along the longitudinal axis thereof and'terminating in a parabolic to present a clean elongated spray flattened at the ends thereof which spray will have an approximately rectangular outline. It will *be noted that all wrench portions or hexagonal portions 14 are kept away from the spray so that there'will be no nicking or deforming of the spray controlled edges due to wrenching or application of a tool thereto.

In order to achieve the proper spray pattern, the bottom of the V-slot terminates onthe tapered portion 15 while the top of the V-slot at its widest portionterminates dome portion, the top of said hexagonal body having an integral beveled portion and a cylindrical portion integral with said beveled portion, the beveled and cylindrical portions having a V-shaped slot therein extending transversely thereof, said V-shaped slot having upper edges of arcuate shape, having maximum separation at the longitudinal axis of the hexagonal body, said upper edges converging t'oward the ends of the V-shaped slot, and lower edge'sconver'ging downwardly to said bore, the said lower edges of saidV-shaped slot terminating in sharp notches in the said beveled portion.

2. The spray nozzle of claim 1 wherein the hexagonal body has an upwardly extending conical portion terminating in a reduced diameter cylindrical head with a bevelled top edge and a bevelled lowerporton terminating in a threaded 'nipple for mounting.
