i Y This invention relates to lawn sprinklers and more particularly to lawn sprinklers including a rotatable sprinkler head mounted on a base, rotation ofthe sprinkler head being effected as an incident to the discharge of water from one or more nozzles.

. An important object of the present invention is to provide a lawn sprinkler of the type yabove referred to in which the rotary element is mountedon the base vin an improved manner so as to be freely rotatable.

Another importantv object of the invention is to provide means whereby the rotatable sprinkler head may be locked against rotatien when desired so as to convert the rotating sprinkler to a stationary sprinkler.

Still another object of the invention'is to provide an improved nozzle construction whereby the kind ot stream discharged by the sprinkler may be adjusted to suit various requirements and also to provide a nozzle mounted on the rotatable'sprinkler head in such a way that it may be readily adjusted to any4 desired positionrelative to the sprinkler head.

' The invention also contemplates the production of a lawn sprinkler of the type above referred to at a minimum of expense while at the same time producing a highquality, neat appearing sprinkler, and in general, it is the object of the invention to provide an improved sprinkler of the class described.

ther objects and advantages of the invention will be understood by reference to the following specification and accompanying drawings in which I have illustrated a lawn sprinkler embodying a selected form or" my invention.

In the drawings: v Fig. 1 is a side elevation. l Fig. 2 is a vertical section through the axis of the rotating sprinkler head and the base. Fig. 3 is a section through the axis of one ot the nozzles shown in Fig. 1.

` Fig. 4.- is a plan of a detail of construction shown also in Figs. 1 and 2, and

Fig. 5 is a view partly in elevation and parti ly in section corresponding to a part of Fig.

2, but showing a modified construction.

Referring now to the drawings, I provide to tit corresponding threads in the outletV aperture 13 ot the base as indicated at 15. 'the tubular post 14 extends upwardly from the base, as clearly shown in the drawings, and a hollow stem 16 is rotatably mounted in the tubular post, bearings 17 and 18 adjacent 'the upper` andlower ends respectively ot' the tubularpost being provided tor so supporting the hollow stein. Adjacent` its upper end, the hollow stem 16 is provided with a vlaterally outwardly projecting flange 19 which provides a downwardly facing, outwardly extending shoulder 20 which is adapted to engage the upper end oit' the tubular post 14 to position the stem in the post.

For preventing upward displacement of the hollow stem ktrom the post, I provide the lower end portion of the hollow stem with a reduced end portion 21, thereby forming a downwardlyV facing seat or shoulder 22 adapted lto receive anannular stop member 23, as clearly shown in Fig. 2. The stop member 23 extendslaterally outwardly beyond .the periphery ot the stem 16 and overlaps the lower end portion ot the post, as indica-ted at 24. The annular stop member 23 may be secured in place on the stem in any convenient manner and in the present in stance, I find it convenient to provide vthe reduced end portion 21 of the stem of such length that a portion thereof may be swaged over the stop member as shown at 25.

The upper end of the hollow stem 16 is provided with screw threading 26 and a sprinkler head 27 including a downwardly vprojecting connecting boss 28, is mounted on bored out andprovided with screw threading fitting the screw threading 'end of the stem.

26 on the upper of the opening The sprinkler head 27 includes hollow arms 28 and 29 which communicate with the interior of the hollow stem 16 and which arms terminate at their outer ends in upwardly projecting end portions 30 and 31. Nozzles such as shown at 32 and 33 are mounted on the ends 30 and 31 respectively of the sprinkler head arms. Y Y

The nozzles 32 and 33 are preferably of an adjustable type so that various kinds of streams canY be discharged by the sprinkler and the nozzles are preferably mounted on,

`locking the head against rotation, I provide a slidable pawl or locking device 34 which is slidably mounted in an opening 35 provided in a laterally outwardly extending flange 36 which is formed as an integral part of the post 14. @ne convenient manner of providing the opening 35 is to cut'or otherwise forma crosswise extending notch or groove in thev periphery of the flange 36.V A

wide ring-like member 37 is then slipped overV the flange 36 so as to close the outer sideof Vthe said groove and the ring 37 may be an! chored in place by identing the same in one or more places, as indicated at 38.V The locking device 34 is provided adjacent-its upper end with a laterally inwardly projecting ridge-like boss or part 39 which is adapted to engage a milled or serrated periphery of the flange 19 of the rotatable stem 16. The lower end of the locking device 34 is bent outwardly to` provide a flange or tab-like Vportion 40 for facilitating adjustment ofY the locking device into or out of engagement with the serrations of the flange 19. The 1n- 'wardl r ro'ectino' ridOfe art 39 valso serves to prevent loss of, or accidental removal of the locking member 34 from the'opening 35, the combined thickness of the projection 39 and member 34 being greater than the width Obviously,- the lange part 40 prevents removal of the locking member from the slot by upward movement in the slot. v

For some purposes, I nd it convenient to provide serrations such as shown at 41 (Fig. 5), in the periphery of the downwardly extending connecting boss 28 of the Vsprinkler head, such serrations being substituted .for similar serrations provided in the flange 19 of `the stem 16, as previously described. When the serrations are provided in the boss instance; with a laterally outwardly extending annular 28 of the rotatable head, the stem 16 may be the pawl will be sprung outwardly slightly at its upperfend so that there will be suilicient frictional engagement between the upper end of thepaw] and the serrations, and between the pawl andwallsof the opening35, to maintain the pawl in such operative position of adjustment. When it is desired to unlock the sprinkler head, the pawl is merely pressed downwardly so that the upper end thereof is disengaged from thesaid serra-` tions.Y

Asshown in Fig. the pawl l34 may be slidably mounted'on a Vflange or `boss 36a which projects laterallyy from the post.14 insteadof in an annular flange such as flange '36 of Figs. 1 and'2. I n this casefthe outer end of theboss 36a is a flat surface provided witlrarecessfor slidably receiving the pawl 34, and ka plate37a overlying the pawl, is securedto the boss so as to retain" the pawl inthe recess.l Also, a pin such as shown at 67 may be provided forpreventing the pawl from dropping downwardlythrough therel cess. The pinelimnates the possibility ot the projecting ridge 39 Ventering intothe recess whereby the pawl might possibly ybefcome jammed in inoperative position.

The nozzles 32 and 33 may be of any conventional form, but f I prefer to `provide nozzlesof the constructionshown in Fig. 3. rThis construction includes a bent, hollow `stem 42 having its lower end 43 rotatably fitting in yor telescoping into, the upwardly` projecting end of the arm,.31 inthe present The hollow` stem 42 is. provided stop flange 44 which is adapted to `be seated on lthe upperend of the part 31 oi the' arm, a gasket V45 of-compressible material being preferably interposed soY as to facilitatethe provision of a water tight oint. A clamping nut 46 having an inwardly extending flange 47 overlying the flange 44 clampsthe flange V44towards-the upper end of the part 31, it

.being understood that theclamping nut 46 vis provided with-internal screw threading 48 which is adapted to engage the external screw threading on the upper end of the part 31. Clamping action of the nut 46 is limit-ed by engagement Ythereof with the end or" the arm part V31, so that the gasket 45is efectivelycompressed sufficiently toV insure :the 'provisionoiiaj' water. tight joint between eff;

'movedA into engagement with the serrations,

iso

the bent stem part Ll2andthe end ofthe Sprinkler arm while permitting rotation-of the hollow stein in the openingof the part 3l, while also serving to frictionally hold the hollow stem in any desired fixed position of adjustment.

The upper end of the stem 4t2 is provided with a tip member which is preferably shaped at its outer end as indicated at 5l, for a purpose which will presently appear. The tip member 50 is mounted on the outer end of the stem 42, preferably by means of'.

a tubular tongue-like part 52 which fits in a. counter bore 53 provided in the outer end of the said stem. The tubular tongue 52 may be a drive tit in the counter bore 53 or it may be otherwise ixedly securedin place, for instance by means of soldering. The tip part 50 is bored out axially, as indicated at 54, and transversely as shown at 55, so that water may pass from the hollow arm 29 through the stem 42, through the bore 5-1 of the tip, and out through the transverse bore 55. Intermediate the transverse bore 55 and the tubular tongue 52, the tip 5() is provided with an enlarged portion 56 having exterior screw threading 57 provided thereon.

A sleeve 58 provided with interior screw threading 59 is rotatably mounted on the tip 50, the screw threading 59 of the sleeve engaging thescrew threading 57 of the tip so vthat by rotation of the sleeve, the same will be adjusted axially of the tip. The outer end portion of the sleeve is provided with an inwardly extending flange part 60 which cooperates with the shaped outer end 5l of the tip to control the kind of stream discharge from the nozzle. The opposite end of the sleeve 58 is provided with exterior screw threading 6l which receives a packing nut 62 which serves to compress packing material 63 between the inwardly chamferred end 6l of the sleeve and the opposite wall '65 of the packing nut. Thepacking 63 prevents leal;n age out of the rear end of the sleeve and also serves to frictionally hold the sleeve 58 in the desired position of adjustment. rl`he nozzle structure above described is such that each nozzle may be completely shut off by screwing the sleeve downwardly on the tip until the inner edge of the flange 60 of th-e sleeve engages the tapered portion 66 of the tip. These parts, being preferably made of brass, will readily seat themselves so as Vto form a substantially water tight joint. The

construction shown is obviously very simple and easy to manufacture so that the cost of production is maintained at a minimum.

The above described sprinkler construction is, in its entirety, quite simple to manufacture, there being nocomplicated parts which require great skill to produce. l am aware that changes may be made in the form and construction of parts and in the manner of assembling same, without departing from `the' spirit of the invention, the scope of which should be determined by reference to the fol lowing claims, the same being construed as broadly as possible consistent with the state of the art.
