LAWN-SPRINKLER.

Specification of Letters Patent.

Patented Apr. 16, 1917..

Application filed May 20, 1916. Serial No. 98,829.

To all whom it may concern:

Be it known that I, FLETCHER W. YoNeE, a citizen of the United States, residing at Tampa, in the county of Hillsborough and State of Florida, have invented new and useful Improvements in Lawn- Sprinklers, of which the following is a specification.

This invention relates to lawn sprinklers and the like, and it has for its object to produce a new and improved nozzle of simple and efficient construction, whereby a whirling spray will be produced.

A further object of the invention is to produce a sprinkler nozzle of the character described whereby the dimensions of the spray may be regulated.

A further object of the invention is to produce a sprinkler nozzle of simple and improved construction by the action whereof two distinct sprays whirling in opposite directions may be formed, the coaction or intersection of said sprays serving to atomize the water, thereby producing an extremely fine and effective liquid spray.

With these and other ends in View which will readily appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described and particularly pointed out in the claim.

In the accompanying drawings has been illustrated a simple and preferred form of the invention, it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations and modifications within the scope of the claim may be resorted to when desired.

In the drawings,-

Figure 1 is a plan view of one form of the device.

Fig. 2 is a vertical sectional view taken through the bulb on the line 22 in Fig. 1.

Fig. 3 is a plan view illustrating a modified form of the device.

Corresponding parts in the several figures are denoted by like characters of reference.

The improved device in its most simple form consists of a tube 15 having at one end an interiorly threaded socket 16 constituting a coupling whereby it may be connected with a pipe, hose or other duct communicating with a source of water supply. At the opposite end of the tube 15 is formed a semispherical bulb 17 the same lying mostly to one side of the tube which latter occupies a substantially tangential position with respect to the bulb. The bulb has a removable bottom plate 18 which may be secured in position by fastening members such as screws 19. The bottom plate 18, is provided with an upwardly bulged central portion 23 forming a cavity 24 in the underside of the plate. The plate is centrally apertured for the passage of a screw threaded stem 25 carrying an approximately conical member designated as a cone 26, the apex of which projects through an aperture, 27, in the semispherical casing. The stem 25 is Provided with a lock nut 29 located, adjacent to the lower face of the bulged swelled portion of the body plate. The lower end of the stem has a thumb piece 30 locatedwithin the re cess 24 which is sufficiently large to accommodate said thumb piece when the cone is adjusted vertically; the parts being secured at various adjustments by the lock nut 29. A guide 31 for the cone is arranged within the chamber formed by the casing and the bottom plate. It is obvious that by this construction the cone 26 may be vertically adjusted to vary the dimensions of the exit 27. It will be readily seen that when water under pressure is introduced through the tube 15 into the chamber formed by the bulb it will, in seeking to escape through the aperture 27, receive a whirling or rotary motion around the walls of the cone 26. The opening 27 is partly obstructed by the tip of the cone leaving only a narrow annular exit, the dimensions of which may be governed by adjustment of the cone and through which the whirling body of water is expelled in the formation of a hollow cone.

Under the modified construction illustrated in Fig. 3 the tube 15 is provided with two separate semi-spherical bulbs 33, 34 having discharge apertures, here designated by 38, 39, through which the apices of the cones 36, 37 project, said cones being mounted and arranged, as hereinbefore described. By this construction the water issuing through the apertures 38, 39 will be whirled in opposite directions, and the whirling columns of water will intersect and be forcibly thrown against each other, thus producing an atomizing action, resulting in an extremely fine spray which, when the water pressure is sufficient,may be thrown a considerable distance and disseminated over a large area with most excellent results.

A tubular nozzle, a semi-spherical casing connected and communicating therewith,

said casing being positioned mainly at one side of the nozzle and said casing having a central opening in the top portion thereof, a

detachable bottom platefor said casing, said 7 bottom plate having an upwardly 10 portion and anupwardly' extending guide, a

bulged conical member guided by the guide and having a threaded stem extending through the bottom plate, the tip portion of the cone extending into the opening of the casing, a lock nut on the threaded stem, and a thumb piece on the stem accommodated Within the cavity formed by the upwardly bulging portion of the bottom plate.

In testimony whereof I afliX my signature.

FLETCHER WILMER YONGE.
