DEFLECTOR-TYPE SPRAY NOZZLE BACKGROUND OF THE INVENTION 1. Field of the Invention These spray nozzles find wide application in refuse cleaning sprays for traveling water intake screens, for the sprays on vibrating screens, for cleaning vegetables and fruits, and in the rinsing and cleaning of materials in motion or at rest. They are also used for impregnating loose material with liquids, diffusing liquids, as in road sprinkling, or removing oil or scum in settling basins.

2. Description of the Prior Art Some nozzles of this general type have previously beenprovided with a tapered pipe thread which requires threading of the pipe on which it is mounted and'which is subject to deterioration through corrosion in the relatively thin wall thickness of small pipe sizes. These nozzles usually are fitted with a fixed size orifice so that different units must be stocked to provide for different flow rates and, accordingly, the inventory required to be maintained is relatively large. Other types require orifice holes to be drilled in the pipe, and these holes are subject to enlargement through wear and corrosion. Special separate orifice bushings have been used with the above nozzles but these are usually of hardened stainless steel and are relatively expensive. The nozzle assemblies of the above type have heretofore also been made to fit only one particular pipe size, and the provision of assemblies to fit these different sizes increases the inventory of parts to be maintained. Still another type requires a large tapered hole to be reamed in the pipe to obtain sealing, and the orifice is integral with the nozzle assembly. The latter then have to be stocked with different orifice sizes so the inventory problem is again present. The above types of nozzles are generally made in bronze for corros ion resistance or in other special hardenable alloys where abrasion is a problem so the material is relatively expensive.

SUMMARY OF THE INVENTION This invention covers a fluid spray nozzle for producing a wide relatively thin spray pattern which is adaptable to mounting on several sizes of pipe and has a replaceable self-locating bushing which may have different sizes of orifice to produce different flow rates. A single body and fastening means may be I used under a number of different situations and the desired capacity may be obtained from a choice of several small bushings with different orifice sizes.

One object of this invention is to provide a single nozzle assembly which fits several sizes of pipe and which has an interchangeable orifice bushing so that only the bushings have to be stocked in different orifice sizes. Since this is a relatively in which one surface of the orifice is always located so the stream of fluid passing through the orifice flows over the deflector without interruption regardless of'the size of this orifice and is so arranged it can only be assembled in the proper manner to accomplish this.

DETAILED DESCRIPTION OF THE INVENTION In the embodiment of this invention shown in FIGS. 1-3 the spray nozzle 20 is mounted on a manifold 21 which has a hole 22 through one wall. This manifold is most commonly made up of a piece of pipe which may be made of steel, brass, plastic or other suitable materials. It may be assembled from various pipe fittings connecting to a source of fluid under pressure, as from a pump, into a tee-shaped header of a length necessary to cover the width of the area to be cleaned by the sprays. Since each nozzle will produce a spray sheet of a width approximately equal to the distance from the hole in the manifold to the object being sprayed, the nozzles may be spaced on the manifold at distances which will give an overlap of the spray pattern on the object to be cleaned. All parts of this spray nozzle are made of an acetal type plastic, such as Delrin or Celecon, to provide a unit suitably resistant to salt water atmospheres, most solvents, and many chemicals.

The spray nozzle 20, as shown in FIGS. 2 and 3, is made up of an approximately rectangular mounting member 31 containing three apertures on its longitudinal axis 32. At the approximate midpoint of this axis there is a central aperture 33, and the with of the mounting member is enlarged at this point, as shown in FIG. 6, to provide sufficient material thickness around the central aperture 33. Also on this longitudinal axis, and approximately equidistant from the central aperture, are two slotted apertures 35 extending through the thickness of the mounting member 31.

As shown in FIG. 4 the central aperture 33 may be considered to comprise an upper cylindrical aperture 33a that extends part way through the thickness of the mounting member 31 and a lower recess 33b that is of enlarged diameter, approximately 127 percent of the diameter of the aperture 33a, and has a depth of about 19 percent of the total thickness of member 31. As shown in FIG. 9, the recess 33b is so formed that a chordal segment 39 is retained in the mounting member. The chord is perpendicular to the longitudinal axis 32 and is located at a distance from the center of aperture 33 just slightly larger than the radius of the diameter of hole 33. The resulting cross-sectional configuration of recess 33b is noncircular because of the chordal segment 39 and it provides a positive alignment for an orifice bushing 40 that is disposed in the aperture 33.

Orifice bushing 40 as shown in FIGS. 5, 7 8L 8, is essentially cylindrical in shape and its length is approximately 1% times the thickness of the mounting member 31. It has a longitudinal cylindrical aperture 41 extending therethrough and the diameter of this aperture may be varied depending on the flow capacity desired. The inner end portion 42 has an outside diameter that is approximately 5 percent greater than the thickness of the mounting member 31 it is cylindrical in shape; and its length is about five-sixth of the mounting members thickness. The inner end portion 42 is followed by a flanged section 43 having a thickness of about one-sixth of the mounting member's thickness and an outer diameter of about 127 percent of the diameter of the inner end portion. A chordal segment is removed from this flange approximately tangent to the inner end cylindrical portion 42 as seen in FIG. 7. The outer end portion 45 of the bushing extends beyond the flanged section approximately 50 percent of the combined length of the inner end portion 42 and the flanged section 43. It is also slightly tapered so that at its outer end its diameter is about 91 percent of that of the inner end portion 42. The longitudinal aperture 41 is not necessarily concentric with the inner cylindrical end portion 42. Depending upon the diameter DX of the orifice aperture 41, the actual centerline of the orifice is so located that the wall thickness T," on a diameter in line with the longitudinal axis 32 of the mounting member, is always constant as shown in FIG. 12. The chordal section 44 of the flange is also perpendicular to longitudinal axis 32. This orifice bushing 40 can thus only be assembled into the central aperture 33 of mounting member 31 so the chordal section 44 of the flanged section (FIG. 7) fits against the flat wall of the chordal segment of the recess 33 (Fig. 9). The frustoconical outer end portion 45 projects outwardly from the mounting member 31 as shown in FIG. 4.

A curved deflector 50 is formed integrally with the mounting member 31 and is approximately trapezoidal in outline. It projects approximately tangentially from the top surface of the mounting member 31 and perpendicular to the longitudinal axis 32. The deflectors width at its juncture with the mounting member, as shown in FIG. 2, is approximately that of the width of the mounting member 31 and, at its outer edge 52, its width is approximately 4% times that of the mounting member, being symmetrical about a plane P passing through the longitudinal axis 32. The deflector as shown in FIG. 4 is arcuate in longitudinal section, having a radius R" of its inner surface 53 about 4% times the thickness of the mounting member. The deflector is so positioned that at the top of the mounting member 31, the inner surface 53 is tangent to the orifice 41 at the longitudinal axis 32 so that the fluid moving upwardly along the inner surface of the longitudinal orifice 41 will flow smoothly onto the deflector. The outer edge 52 of the deflector is located approximately 3.42 times the thickness of the mounting member 31 vertically above the top surface of the member about 1.6 times its thickness.

The spray nozzle is assembled on the manifold 21 by pushing the projecting frustoconical outer end portion 45 of the orifice bushing into a straight predrilled hole 22 of the proper size in the manifold. A U-shaped bolt 60 is then placed around the manifold 21 so that its threaded projecting legs 61 fit up through the slotted apertures 35 in the mounting member as shown in FIG.'4. A nut 62 is then placed on each threaded leg 61 and tightened securely to hold the nozzle firmly on the manifold and to obtain a fluidtight fit of the bushing 40 in the hole 22 in the manifold. The threaded projecting legs 61 of the -U-shaped bolt 60 are circular in cross section, but the curved portions between these projecting legs are generally rectangular in cross section, as indicated in FIG. 2, to permit them to flex more easily around the various size manifolds on which they may be assembled.

While the most common orifice bushing 40 may have a straight cylindrical hole 41, as shown in FIG. 4, the rate of discharge may be increased by the alternate internal constructions shown in the embodiments of FIGS. and 11. In FIG. 10, the inlet end 71 of orifice bushing 70, has a converging section 72 gradually varying in cross section from its inlet end toward a very short cylindrical section 73 which is of the nominal orifice diameter. In one illustrative example of this construction, a bushing having a nominal 5/16-inch diameter orifice would have the longitudinal axis of this orifice at section 73 offset from the axis of its outer end by three thirtysecond inch. A conical tapering converging section having an included angle of 7 would result in an inlet diameter d! of approximately 0.44 inches and a cylindrical discharge section one-sixteenth inch long having a 5/1 6-inch diameter d2 where the overall length of the bushing is 1% inch and its cylindrical inner end outer diameter d3 is approximately 0.785 inch. The minimum thickness at the inner end 72 is about 0.14 inch.

In FIG. 11 the inlet end 86 of orifice bushing 85 has a converging section gradually varying in cross section from its enlarged inlet to a very short cylindrical section 87 having the nominal orifice diameter at approximately one-fourth to onethird of its length followed then by a diverging section enlarging towards its opposite end. In one illustrative example of this construction, a bushing having a nominal 5/ 16-inch diameter orifice, the same outside configuration and the same minimum wall thickness of about 0.14 inch at its inner end as the bushing of the previous example, would have the longitudinal axis A of this 5/16-inch orifice offset from the axis A1 of its outer diameter by three thirty-second inch and tilted about 3% relative to axis A1. A conical tapering converging section 88 having an included angle of about 13 would result in an inlet diameter of about 0.40 inch for a length of three-eighth inch to the inner cylindrical orifice section 87 which would have a length of one-sixteenth inch and a diameter of five-sixteenth inch. From the inner cylindrical section 87 the passageway would again gradually enlarge toward its discharge end 89 where its diameter would be approximately 0.40 inch and the included angle of the conical diverging section would be about 7.

It is to be noted that while conical sections were referred to in the above examples similar constructions covering converging and/or diverging sections in which the cross sections vary according to some exponential value resulting in smooth curved sections in lieu of the straight tapering sections shown are equally disclosed in this invention.

In one embodiment of this, invention, the mounting member 31 is seven-eighth inch wide by three-fourth inch thick. The

' slotted holes 35 are eleven thirty-second inch wide and as shown in FIG. 6 the centers Y of one slot are thirteen-sixteenth inch long with the distance 2X between the end radius center of one slot and the adjacent inner end radius of the next slot is 2% inch. The deflector is thirteen-sixteenth inchwide at the mounting member and 3% inch at its outer end with the inner radius R of the arcuate deflector being 3 17/64 inch and its outer radius Rl" of the stiffening ribs is 3% inch. The discharge edge 52 of the deflector is 2 9/16 inch above the top surface of the mounting member and projects 1% inch horizontally from the midpoint of the mounting member. The normal range of pipe sizes on which this nozzle is used is 1 inch to 3 inches inclusive and orifice diameters of three-sixteenth inch to one-half inch are provided.

It is to be understood that the form of this invention is to be taken as a preferred example of the same, and that various changes in the shape, size and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.
