LAWN SPRINKLER.

Application filed June 1, 1927. Serial No. 195,707.

the head being such that when the parts are arranged in one position the water will be discharged in a circular spray. V In utilizing the ordinary type of sprinkler for lawns or gardens, such sprinklers throw the water on a path, sidewalk or roadway, this being disagreeable for the passcrsby, as well as wasting the water. With my improved sprinkler, the proper sprinkler head may be'chosen to throw the water to drop parallel to paths or sidewalks and to dischargew'ater on a parkway parallel-to a sidewalk and roadway.

.Another important object of the invention isthe provision of a sprinkler-head which is adjustable so that the proper spray may-be obtained in case of vanation in the pressure of the water. supply and so that either a qoarse or a fine spray may be ob- T tained... l v

Another object is the provision of a sprinklerhead of this character which is so 1 constructedthat-when properly adjusted the flow of water therethrough will be cut off, the advantage or this being that in cases plurality of the sprinkler heads-are used in connection with a buried irrigating pipe,

any one or more of them may be cutout without interfering in any way with the operation of the remaining-ones. Another object is the provision of a sprinkler head of this character WhlChdS so constructed that the water will rise higher into the air before being converted into spray, this feature being "important inasmuch as'ittends to prevent the formation of a puddle in the immediate vicinity of 'the sprinkler head. 1

An' additional objectisthe provision .of a device of this character which will be extremely simple and-inex nsive in manu- --fa'cture,=easi1y converted om one form for roduclng a circular-spray into. the other orm for producing a strip spray, and to 'athird form if so desired, to produce a semi-circular spray, which will be highly eflicient in use, durable in service and a general improvement art.

With these and many other objects in through. I

view which will morereadily appear as the nature of the'invention is better understood, the same consists in the novel construction, combination and arrangement of parts, which will hereinafter be more fully described, illustrated, and claimed.

The essential features of the invention involved in the. carrying out of the objects indicated are susce tible to modification; but a preferred 'em, odiment of the invention is shown in the accompanying drawings, in which:

PATENT OFFICE.

Figure 1 is atop plan view of the device showing the same'in assembled relationship when a circular spray. is desired.

Fig. 2 is a. sectional view taken substantially along the lines 2- 2 of Figure 1.

-Fig. '3 is a sectional view taken substantially along the lines 3-3 of- Figure 2.

' Fig. 4is a view similar to Figure 1, showing the partsv in assembledv relationship when a semi-circular spray is desired.

" Fig. 5 is a sectional view taken substantially along the lines 5-5 of Figuret, and Fig. 6 is a sectional view of a still further arrangementof parts that are contemplated when a vertical strip spray is required.

The various figures described above adequately illustratev my invention, and the followin detailed description is commensurate with t e above mentioned drawings in enabling an artisan to construct and assemble the constituent parts of the same.

Referring more particularly to the drawings' and especially tie-Figures 1, 2 and 3, my vsprinkling device comprises a body 10 preferably of cylindrical form having a tion 13 shown in dotted'lines in Figure 2,

and the upper end of which is provided with a valve seat 14. When my sprinkler is mstalled, it is designed that the top of the portion 11 be flush with-thesurface of the ground so that when the lawn is cut the sprinkler-will not be in the way of a lawn mower or the like. 'A' web 15 is provided within 'the'body portion 10, which web has a threaded aperture 16 extending there- Screwed within the upper portion of the bore 12 is a bafile mem er formed'as of a conical disc 17 having a conical seat 18 on the under side thereof. This bafile member is provided with a reduced shank 19 threaded as at 20 to be received Within the threaded portion 16 of the web 15. This 5 discis provided with a head 21 having a ternal marginal flange is provided above the web 15 for a p'u'rnoseto be described hereinafter. Y The operation of this form of the device is as follows:

Assuming that a circular spray is des red, the bafie member 17 is screwed into position in such a manner as to obtain the desired I thickness of spray. If a thin spray 15 demag-ace insure full protection to the building by keeping the same dry so that the plaster of the same will not become damaged through sediment or rust that may lurk in the pipes.

The formshown in Figure 6 is. adapted for use when a vertical spray is used as between sidewalks in a park or between buildings that are close together and the like. In this case, a small cup designated as at 17" is frictionally inserted within the recess in the body member 10. Thissmall cup 17" has an outwardly extending annular flange 18" and a slot 19 is formed within the same so that water issuing from the pipe 13 will pass around andthrough the spider 15 and through the slot 19 where it will be projected upwardly, forwardly and rearwardly in the shape of a narrow Web.

sired, thebaflie member 17 may closed upon the valve seat 14 to such a position as to obtain a narrow circular outlet for fluid;

From the foregoing description and a study of the drawings it will be apparent that I have thus provided a very simply 45 the tubular member.

50 180 'aroun and if a thicker spray is desired, the baflle member 17 may be elevated from the valve seat 14. -When water is turned on in the pipe 13, the same will pass around the web 16 a the internal annular flange 30 and ou tv ari ily between the valve seat 14 and the surface 18 in the form of a conical spray.

. This form of the device is particularly useilll ful for irrigating large areas of lawn, flowers, shrubbery and the -l1ke.

When it is desired to form a spray of semi-circular form, the device shown in Figures 4 and 5 is employed. The same bod 35" portion 10 is used, but the bafiie member 1 is removed and a modified form of baflle member 17' is substituted therefor. TlllS member comprises a tubular member 20 which is firmlyfi pressed Within the depres- 40 sion in the body portion IO-and rests against the flange 30 where it is held frictionallym position. The tubular member 20 is in; ternally threaded as at 21 and a plug having threads thereon 1s dlsposed within The plug 22 has a conical surface 23 and a conical valve seat 14 is formed within the tubular'member. A slot 25' is out within the side of :the tubula member and this slot may be out either d the tubular member, or more or less as may be desired. Adjustment of the plug 22 will secure the roper degree of thickness of the. spray. his 'devlce 1 s particularly useful when it is desired to llll- 66 gate lawns adjacent the side of a building or the like, and the spra may be directed outwardly from the buil ing so that water may not be thrown against the building where it will trickle down the s1de of the (W same and form puddles adjacent the building. Furthermore, this'type of spray will constructed and consequently inex ensive sprinkler head which is convertible or use either in producing .a circular spray or a strip like spray, the device therefore having the great advantage of being capable of use under a wide variety of circumstances. Owing to the simplicity it is to be observed that there is practically nothing to get out of order and that the device should consequently have an extremelylong life.

' While I have shown and described the preferred embodiment of the invention, it is of course to be readily understood that I reserve the right to make such changes in the form, construction and arrangement of parts as will not depart from the spirit of the invention or the scope of the subjoined claim.

Having thus described my invention, what I claim, is:

A sprinkler comprising in combination a body portion having a passage therethrough terminating in a cylindrical discharge opening, a web in said passage, a conical valve seat flaring from said discharge opening, a baflie member comprising a conical head and a shank removably carried by said web. and adjustable to position said head with respect to said seat, and an annular flange in said passage between said discharge opening and web and cooperating with-the wall of said discharge opening to form a seat for the reception, on removal of said conical head and shank, of any one of a plurality of variant nozzles, each having its inlet end sha ed to be frictionallyre'celved and retained in the discharge opening against the flange.

In testimony whereof I have signed my name to this specification.
