SPRINKLER NOZZLE Filed Dec. 3, 1951 gmnmtoi Patented June 6, 1933 UNITEDISTA i WALTER B. IVEY. or isournimcizsonvirrn, FLORIDA sr mxm fimzm Application filed December a, 19 Serial no. 578,808.

This invention relates to new and useful improvements in water sprinkler nozzles and its object is to provide an improved sprinkler nozzle which due to its construc- 5 tion will offer little resistance to water and will insure an even distribution of water. Another object is to provide a sprinkler nozzle which is simple in construction and easily adjusted from a light spray to heavy dropsand one which may be manipulated to project water in half spraying circle when desired. 1 y

Referring to theaccompanying drawing, which is made a part hereof and on which similar reference characters indicate similar parts, 5

Figure 1 is a sectional view in elevation showing the improved sprinkler nozzle,

Figure 2, a" perspective view of the distributor head whichis used to produce a complete spraying circle,

Figure 3, a perspective view of the distributor head which is used to produce a half spraying circle, and

Figure 4, a modified form of the sprinkler nozzle.

In the drawing reference character 10. indicates the casing of the sprinkler nozzle, the upper portion 11 being reduced in size and provided with threads 12 on its interior surface. A deflecting element 13 comprising a plate 14 and a depending portion 15 is secured to the casing by means of,

threads 16 on the portion 15. Instead of having the element 13 and the casing 10 of separate parts it may be desired to form these parts of a single casting which would reduce the cost of manufacture considerably. The deflecting element 13 is further provided with a bore 17 in communication with the interior ofthe casing 10. The center of plate 14: is provided with a cone-shaped depression 18 and a flat rim 19 on its upper side.

The lower portion of the casing 10 has tributor heads 22 and 23 are threaded. The bolt 21 is threaded through member 20 and is held in fixed position by a nut 241 resting against the lower; side of the member 20.

The bolt 21 is small enough to allow water to flow through the bore 17. V

The distributor head 22 is provided with acone-Shaped depression 25 in one end and a flat surface 26 on "the other. The head 23 is similiar in construction to the head 2 2 and is further provided witha cut down edge indicated at 27 and extending a distance equal to one-half the circumference of the head for a use which will later be described.

The casing 10 may be secured to a supply line by the threads 28 formed on the in terior surface below the member 20. l Figure 4 is a modified form of the improved sprinkler nozzle which is adapted tobe attachedto a garden hose or the like and-held in position by a support driven inthe ground. i

i This form comprises a casing 28 having a deflecting plate formed integrally on its upper end and similar to that shown in Figure l at 14. The casing 28 is provided with a bore extending from the top, downwardly and outwardly through the side.

The casing isalso threaded at 29 for the so hose connection. 1 v y A pinor rod 30tl1readedon its upper end isturnedthrough the'bottom portion of the finFigures l and 4. To operate the sprin- 3 lrler,the topmost head which always serves as a lock for the head adjacent the deflecting element isloosened. The lower head is then rotated in either direction until thedesired opening is obtained. The upper head is tightened against the lower to hold it in -fixe-dposition and a spray from a light mist to very heavy drops can be produced -de pending on the position of the lower head even distribution of water and tends to inv crease the area covered by the spray circle.- In using a fiat end head as is usually the case the water is thrown in a manner similar to a stream from a hose as it strikes a fiat surface; the water is deflected in a very irregular manner. The structure described overcomes such a condition and the results produced are quite an improvement over other sprinkler nozzles. I 7 By simply reversing and interchanging the heads 22 and 23 a half spraying circle is produced. The edge of the cone-shaped depression in the head 23 is engaged by the deflecting clementleaving an outlet formed by the cut-down edge 27 through which the Water is forced producing a half spray circle. In this case the head 22 serves as a lock for the head 23.

In the above described sprinkler head it is clearly seen that a device results bywhich water may be projected in a variety of forms varying from a fine mist to heavy drops and so constructed that it is also possible to produce a half circle spray when desired.

It will be obvious to those skilled in the art that various changes may be made in my device without departing from the spirit of the invention and therefore I do not limit Having thus fully described my said invention, what I claim as new and desire to secure by Letters Patent, is:

l. A spray nozzle comprising a casing,

a deflecting element mounted on said casing,

the upper surface of said element having a cone-shaped depression therein and an axial bore in communication with said casing, a support mounted in said casing having a rod adjustably secured therein, said rod extending upwardly through said bore, a pair of interchangeable and reversible adjustable heads mounted on said rod, each head being flat on. one end and having a cone-shaped depression in the other, part of the edge of the cone-shaped depression of one head being reduced to provide an opening when said head is positioned in contactwith'said deflecting element, the upper head serving as a lock nutfor the lower head 'whenthe fiat surface ends are positioned to contact one another, substantially as set forth,

2. In a spray nozzle, a casing having intact with said casing for producing a variationof sprays, substantially as set forth.

In Witness whereof, I have hereunto set my hand at South Jacksonville, Florida this 4th day of November, A. D. nineteen hundred and thirty-one.
