Serial No. 525,099. This invention @elates to automatic lawn spri.:nklers, @nd inore particularly to a sprinkler of the above nature adapted to producb an atomiz6d "rose" spra@ for uniformly. dis5 tribtitin cr a stream of water froin a, hose over a, lai@ge Wrea of a lawn. One object of the invention is to provide a lawn sprinkler of the ,tb6ve na-ture, iii which the water to be distributed is first b@oken up 10 by a, rotpting turbiiie, and then passed out of the sprinkler c@sing tlirough an ap6rtured @ap co ver:L . ng s d r ine w ereb-v a s-oreading ced. S!pf-rLi'rythiserp 'dct is to provide a lawn 15 sprinkler of t above na-tur'e h@.ving improved means for supporting it in raised position above the surface of the ground. A further object is'to provide a lawn sprinkler of the ,tbove nature which may be 20 used alone or in series with other sir@ilar sprinkler units, the ftclja6ent units being connected together by a pluralit.@ of 'hose seetions. A f Lirther object is to provide a lawn 25 sprinklier o'L the above nature which will be le in construction, inexpensive to manu=0, easy to inst,,tll ,tlid manipulate, free from vibration, compact, ornaimental in appearaiiee, and verv efficient and durable in 30 tise. IVith 'ul-iese ind other objects in -view th:ere h,Lve been illustrated on the accompanyindr.awings, five forn-is ii, which the inventio-n may be conveniently embodied in practice. 3,5 In 'uhe drqwin(-Ys: Fig. I represents a perspective view; of the first form of lawn sprinkler embodyink the iiivei.ition as it appears in operating position supported above tl-ie ground with ,t hose noz40 zle connected tl-iereto.

Fig. 6 is an e-nd view@of the sprinkler.showli in Fig, 4. Fig . 7 is a perspective @vi6w of -a foiirth r)5 form of the invention, having flat side wings for sup'poriting the n6zzle clos6 to t,he groiind. Fig . 8 is a longitudinal @sectional view of the same. Fig . 9 is a pe@spective view of one of the 60 @turbi ne members em'Ployed i,n each for@a of the invention. Fig . 10 is a top plan view of the spri-n'kler chsing of the first form of the invention, with the turbine and cap removed to show the in- 65 terior construction. Fig . 11 is a perspective view similar to Fig. 7 of a fifth form of the inve'-ntion having open si.de wings constructed of heavy wire. R @eferring now to the drawliws il'i which 70 like reference nun-ierals denotle correspojiding parts throughout the several views, the first form of lawm sprinkler showii in Figs. 1, 2, and 10, consists of a hollow @po6l-shape4 cylind rical vertical casiiig 10 having a;n c-n- 75 la;rge d knurled lower flanoe 11 ancl an annular @ bead 12 at its uppe; end. . Extending inward ly from and inte@),,rally connected to the bead 12 . is a flat annular section 13 havino, a depressed central inv6rted dome 14 80 formed therein, said doine beino- provided ivith ,i @lurality 6f angular'de'pr-essions 15, each of which has a slit 16 on one side thereof', there beiii three of such depressions @15 in the ptesent instance. 85 Motinted- upon the top of the casing 10 is a cap member 17 having a rai@ed flat top 8ecn w tio - 18 ithin -which is a eircul,,tr olitlet aperture@19. Theflatt6psectionl8is-integr,,@lly 90 connected at its o-Liter peiiphery @vith a conical downwardlv-inclined section 20 having an inturned knurled annular bead 21 2at its lo-wer end bent tightly about the bead 12 at the top of the ca,sing I . 0. Within the space between the dome 14 and top section 18 of 95 ti-le cap member 17, a, turbine disc 23 is molintod. As most clearly sho@vn in Fig. 9 said tu@bine disc is provided -with a plurality of flat radial sections 24 five in this @, I f100 iiistance, separafed b-v an equal number o

,-Iownwardly spiral-sh,-tpecl convex ribs, the oliter ed@-res 25 of said ribs i-iormally resting up()n the -Lipper wall of the.dome 14. The ttirbine d;.sc @3 has t central aperttire 26 for looselv fitting arolind a vertical spindle 27 -which has a reduced lo-wer end pas ino, throu _gh @ an- apertiire at the @b6tt6iTi of tl-ie dome 1,1 and he-acled over at 28 under the lower wall tlie@.,eof. The dian-ieter 6f the -d' 23 is s'li(,htly less t-haii that of the iipper -part of th---dom6 14 as @hown in Fio,. 2 I 'n The tipper el-id of the spirldle 27 is @roih-e ii vided with a flange 29 f or limiting pNvard inovement of the turbii-ie clise 23 under the press-Lire of the -,vlter -I)a@@iiio,, tlir6uoh the-sprinlcler.

In order to sul,3@ort the sprinkler at an elesio vated position above-the lawn, provi n is inacte of a -vertical gio-Lind-en-aging ridd 34 zn having a ointed lower extr-erqity 35 and p hori7-aiital tipper, section 36, stid,upper seetion ineltiding a resilliept clip 37 adapted to :,@1) fi@ snugly and d(,@tachably around the casi@o, 16 betweeii the fl,,in-es 11 and 12 thereof, 0 po a zon in the operi.tion of th.e first forin of tllie 9,5 inventi6n, the water, from th,e hose 321 ill passiiio- -Lipwardly tlirough the slits 16 of the depressions 15, will impinge against the turb-Ane disc, 23 and be deflected outwardl-Y into,t-he space 22. The wal'or will then move 1-.iNvardly and pass upwardly out of the nozzle tlirough the central aperttire 19,,elii6rgiii, fron@ the s rinkler in aii interrup'ued stream p ,of fir,.ely divided aton-iized drops of water, which will spread outwardly @6yer a- wide 45 area due to 'the rotative energy stored up therein. The modifi6d forli-i of sprinkler shown,.in Figs. 3,,4, And 6 comprises a hori2ontal shell 38 ha-ving,.one end 39 closed a d the, other - n end 40 threadecl for receivipg a couplin 41 9 fastened to,.the end of a hose 42, as sl-iown in Fig. 3.

The curved section, 43 is ed,intearal a downwdrdl ex@ y t strip 45 sectired to the top of a, woodcii groun,d-engagitig post 46, as by a pair of screw s 47. The top of the sliell, 38 is pro-@,,-ded@ with an@ inverted dome 48 siiiiilar in all, respects to the dome- 14 shown i-,i the first. form of the in,7-Ilt ion-. @Thii@, the dome 48 is perforated at tliree poiiits 49,@ as before, to perinit the - passao,e of wate,r upwardly therethrough for in rotatiny a turbine disc 50 identical. with t@e tlirbine 23 previously O-esc@ibed.
