2 Claims. (Cl. .29969) The present invention relates to new and useful improvements in lawn sprinkler Thev primary object of the inven ion is to provide a sprinkler best adapted for use in spraying lawns that can be readily moved from place t place, as desired; and which is adjustable vertidecreasing the distribution `of water therefrom. Y

Another object of the invention is to provide a lawn sprinkler including a sprinkler head which will be operated or rotated by the force of the water, said sprinkler head being mounted in suitare practically unexpcsed to the ow of water through the sprinkler head.

The invention also consists in certain other features of construction and in the combination several parts, to be hereinafter fullydescribed, illustrated in the accompanying drawings and specifically pointed out in the appended claims.

In describing my invention in detail, reference I will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which:

, Figure 1 is a side elevational view of alawn sprinkler. embodying the featureso the present invention.

Figure 2 is a top plan view thereof.

Figure 3 is a vertical sectional view Figure 1.

ent invention, a means has been provided for taken subf Figure 4v is a horizontal sectional view takenl substantially on the line 4 4 of Figue. I

Figure 5 is a detailed sectional view of the lower end of the sprinkler illustrating the connecf tion with the nozzle of a hose. Figure 6 isa detailed sectional view of one 0 the sprinkler arms taken substantially on the line 6-6 of Figure 1.

Referring to the drawings for a more detailed -description thereof, the improved numeral is supported on legs 'Il which are secured to the tube l0', a's indicated I2, the opposed ends of which are connected, as indicated at I3, -to a. coupling' Il mounted onthe lower end of the tube Il. The legs Il present substantially 'the shape of a tripod and are moved over a lawn. as desired. 'Y As I have indicated, the tubular section 9. telescopes,within'the section Ill and isreadily extensible for increasing r decreasing the height 'of the sprinkler. In accordance with the presvided with exteriorly the tubel l n on the supported a leather,

rectly above the washer Awasher I8 and packing I9 will provide locking the upper section 9 in its adjusted position and referring more particularly to Figure 3 of the drawings, it will be observed that the lower end of the tube 9 flares outwardly, as indicated at I5, for contactual engagement with the wall of the interior of the tube I0. 'I'he upper end of the tube Il! is provided with exteriorly formed threads I6 which-receive a cap nut I1, said nut adapted to lock the tube 9 in its adjusted position, as will hereinafter appear. The upper end of interior thereof is formed with indicated at I8, on which is or the like, washer I9. Di- I9 is positioned a exible packing member 20 which is retained in place by means of the cap nut l1. When desiring to raise or within the tubular member I0 the packing nut I1 is rst released and the'tubular member ,"9 moved to its desired position. frightening the packing nutywill then securely retain thetubular member 9 in its adusted position. Use of the a water a convexed seat, as

tight connection within the cap nut l1. The sprinkler reference numeral 2l is rotatably mounted -on the upper end o'i the tubular member 9. The

upper end of the tubular member 9 is provided with exterlorly formed threads 22 which receive 23, the latter being also pro- I an extension collar formed threads 24. Adjustment of the head 2l is accomplished by loosening or tightening the extension collar 23. A diskshaped washer 25 is held on the upper end of the collar 23, said' washer being formed with a censprinkler which at 4t from water,

tire assembly including be readily tral opening 28 which communicates with the Pipe 21. The lower outwardly, as indicated at 28, and rests upon the washer 25, said pipe revolving within roller bearings 29. 'A relatively thin metal retaining member 30 surrounds the pipe v21 and is disposed'over the roller bearings 29 for protecting the same dirt, dust, and the like, and the enthe roller bearings 29 held in position by means said nuty beingl interiorly and retainer 30 are of the cap nut 3l,

Athreadedvifory engagement with the threads 2l of the collar 23. By this construction the discharge 9 and I0 and into of water through the sections attached therethe pipe`21 and its sprinkler arms tofwill cause the pipe 21 to rotate retaining' memberl 3l will protect the bearings lower the tubular member 9 Y head-generally deposited by the end ofthe pipe 24 is flanged within theu bearings 22.* -Provision of the washer .25 and,

' upwardly through the sections 9,v

` per end of the pipe 21 is formed with an angular which extends upwardly and section of tubing 34 laterally therefrom, said section being also formed with a series of openings through which water is discharged. The action of 21 and outwardly through the arms 32 will effect a rotary motion to the entire head 2| in a manner well known in the art, and as I have indicated Water will also be discharged through the end of the section 34 which will be revolving with the pipe 21. The construction of the head 2| is such that the leakage of water is substantially precluded.

The sprinkler s is adapted to be connected with.'

a water outlet through a section of hose 35, such as is shown in Figure 1 of the drawings. For attaching the hose to the sprinkler, the lower end of the tubular section I is provided with exteriorly Aformed threads 36 by means of which an elbow coupling 31 may be attached thereto. The end 38 of the hose 35 threadedly engages vthe coupling 31 thus providingv a free passage of water from the hose 35.

If desired, the cap nut I1 may be formed with a pair of laterally extending arms 39 adapted to be engaged for tightening and loosening said nut in the adjustment of the sprinkler.

It is thought that the operation and advantages of the sprinkler are readily apparent from the above description when taken in connection with the accompanying drawings.

Also it will be understood, of course, by those skilled in the art that variations in the herethe water passing I0 and pipe inabove-described device involving the substitution of substantial equivalents for the devices described are intended to be comprehended within'.

the spirit of the present invention and that the invention is capable of extended' application and is not conflnedto the exact showing of the draw- A ings nor to the precise construction described and, therefore, such changes and modications may be made therein as do not affect the spirit of the invention nor exceed the scope thereof as, expressed in the appended claims.

What is claimed is:

1. In a lawn sprinkling device, a tubular head of approximately semicircular formation 'having the ends closed, the said head having its end portions depending and provided with a plurality of longitudinally spaced discharge apertures at one side thereof, a vertically depending pipe having communicative connection with the center of the said head and adapted for connection with a, supv ply conduit, and an angular discharge tube pro- Vfeed pipe having -end of the said pipe and jecting upwardly from the center portion ofthe head. I

A 2. In a sprinkling device, a vertically supported tube, a tubular section slidably mounted in the rst mentioned tube for vertical adjustment, a cap nut mounted on the upwardly projecting end of the adjustable tube section, an upstanding mounted within the cap nut, a tubular sprinkler head of approximately4 semicircular curvature having communicative connectionwith the upper having its ends closed and depending with relation to its center pdrtion, the said depending end portions of the head having a plurality of longitudinally spaced disand a tubular projection having communicative connection with the center portion of the `head and extending upwardly therefrom..
