BY WW 8m nited States Patent SPRINKLER HEAD Walter J. Reed, Big Spring, Tex.

Application January 6, 1954, Serial No. 402,505

2 Claims. (Cl. 299-114) The present invention relates to new and useful improvements in sprinklers which may be used with various types of liquid as an improved sprinkler for industrial and other purposes.

An important object of the invention is to provide a sprinkler head of circular shape having an outlet at its center and feeding liquid under pressure to the head in a manner to set up a swirling action as the liquid is discharged to produce a conical swirling spray pattern having a centrifugal force to cover a Wide area.

Another object is to provide multiple inlets for the sprinkler head to accelerate the internal swirling action of the liquid for more effectively creating the centrifugal discharging action thereof.

A further object is to provide a device of this character of simple and practical construction, which is efficient in operation, relatively inexpensive to manufacture and otherwise well adapted for the purpose for which the same is intended.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure 1 is a top plan view;

Figure 2 is a side elevational view;

Figure 3 is a horizontal sectional view taken on a line 33 of Figure 2; and

Figure 4 is a vertical sectional view taken on a line 4-4 of Figure 2.

Referring now to the drawing in detail, wherein for the purpose of illustration I have disclosed a preferred embodiment of my invention, the numeral 5 designates .a substantially flat, hollow, circular sprinkler head having circumferentially extending slots 6 and 7 at diametrically opposite sides to form a pair of inlet openings.

A longitudinally divided nipple 8 which may comprise a pair of pipes 9 and 10 to form parallel passages 11 and 12 are united at one end to provide a common neck 13 to which a suitable coupling 14 is connected for coupling a hose 15 or other Water or liquid supply thereto. One pipe 9 is suitably connected tangentially to inlet 6 and the other pipe 10 is curved in the arc of the head 5 and tapers toward its extremity and is suitably connected tangentially to inlet 7, whereby the pipes 9 and 10 will supply liquid under pressure in a uniform tangential direction to diametrically opposite sides of the head to set up a circular swirling action of the liquid therein. A centrally disposed round outlet 16 is formed in the top of the head 5 and is of a diameter substantially 2,747,937 Patented May 29, 1956 less than the inlets 6 and 7 to maintain a relatively high velocity of liquid in the head.

When the device is constructed for use as a lawn sprinkler the head 5 is supported on downwardly diverging ovate runners or feet 17 to facilitate sliding the sprinkler over the ground.

In the operation of the device, the tangentially supplied liquid entering the head 5 of the sprinkler will set up a circular swirling action internally of the head and which will impart a similar action to the spray as it leaves the outlet 16 to produce a centrifugally influenced conical spray pattern to spread the liquid over a relative wide area.

When the sprinkler is used for industrial purposes the runners or feet 17 may be omitted.

The multiple inlets for the head prevent lagging of the circular swirling action of the liquid at any portion of the head by accelerating the swirling speed.

From theforegoing, the construction and operation of the device will be readily understood and further explanation is believed to be unnecessary. However, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the appended claims.

What is claimed as new is as follows:

1. A sprinkler head comprising a substantially fiat, hollow, circular body having a plurality of circumferentially elongated inlets at its side portions and a central outlet at its top portion, and a plurality of fluid supply lines connected in a tangential position to the respective inlets to set up a circular swirling action of the fluid internally of the head, said supply lines extending outwardly in parallel relation to each other at one side of the circular body and merging into a common neck having a coupling for attaching to a fluid supply source.

2. A sprinkler head comprising a substantially flat, hollow, circular body having a plurality of circumferentially elongated inlets at its side portions and a central outlet at its top portion, and a nipple having coupling means at one end for connecting to a source of fluid pressure, and a plurality of fluid lines diverging axially from the other end of said nipple and connected at their free ends to the respective inlets at a tangential position to set up a circular swirling action of the fluid internally of the head, ovate runners depending from the bottom of said body for supporting the body above a supporting surface, said runners being inclined outwardly in diverging relation to each other and arranged with their longitudinal axes parallel to the fluid lines to facilitate sliding the body over the ground by a pulling force subjected to the fluid lines.
