The `foregoing,,const'tuting the actuating f vmeans forrotatingythe nozzle, is similarlto thatfshown in my above,.-identified applica-yl tion and 1I have generally, referred to .it in this case in order toshow a completely op?,`

I'"erative structure.

.f The topA of nozzle 1 0, labovev nozzle por-y l tion 11, is recessed at 13 therebyl providing pivot rlips l14,- between which means, vpreferably in the lform of "a lever l15, `is disposed.v

A substantially'horizontal .pivot pin 16, `ex` `tends through saidlips and levery and per-k mits therlatterto be rocked a's'the nozzle l0y rotates, or 'permits 'ofrv rocking, adjusting positions, a'sfwill A'presently appear.

Said" lever `:15, yhas 'a deflecting end 17,1

projecting from ,one side of pivot 16 and v terminal 18, of said nozzle portion 11. The

` outer stream delecting face 19, ofsaid de'-v flecting end 17 is vsubstantially and' preferably hat andthe margin l20 'is semi-circular, as shownv in Fig.4. This form 'of face,

Aim

vWhen advancedinto contact with the stream issuingfrom' end18, not only attensfthe longitudinal4 arch of the vstream,butv also `spreads thelatter, and in addition, trans- .,versely, arches the same, as will be flater described. `Immediatel in the rear *of the kouter liat face 19, vthe efl'ecting end is provided with laterally notched lportions which are'v preferably in the form of arecess 21 extending throughout the width of'lthe deilectingend; 17, the kbase portion .22, of

` said recess, being inclined to the "normal plane of yface 19, andl merging into a shoul der 23, of vsaid lever 15. A lpreferably re-l silient plate 24,. proportioned to have an anchored" thereto at 25. An4 adjustment, in the form of aj screw26, threaded in said leflecting end 17, provides means foriieX- ingsaid p1ate24'to vthe right of Fig. 5,V Y A' 11o.

to variously decrease the'eii'ective depth of they recessedportion 21,,With fwhichthe stream engages*- v'l[n" l ?ig. 5, the plate I' 2.4,

liesV in fiat abutting relation lwith the base 22, of said recess, so that shoulder 21, opening through the lateral edges of end 19,

forms laterally disposed notched portions4 .on the opposite side of pivot 16 in overhanging relation to the base 1, and the same is preferably provided with an extensionl 31, forming stock vfor an adjustment screw 32. A cam follower or rod 33, extends through the actuating end 30, and may be provided with a cranked end 34, to facilitate swivelled adjustment of said rod. The screw 32, serves to hold said rod in' its adjusted position. Thelower end 35,depends downwardly into the path of a cam, which I will next describe.

- I have shown a cam fixed or cast integrall v on the lid 2, of base 1, the cam being substantially concentrically disposed about the nozzle 10. or rather about the axis of rotation of said nozzle. 'Said cam includes hill portions 36 and vale portions 37 symmetri# cally disposed and arranged to provide for control of the sprinkling stream so that the latter will be confined tol an area bounded by straight-lines. In the present construction, thek cam is. designed. to control the stream 'so-that a square area will be sprin-l kled. The lower end vof rod 33, traverses the periphery vof the cam and when riding againstthev hill portions 36, the deflection end`17 is depressed to flatten the stream to a relatively extreme vextent whereas when the rod enters the vales 37, the lever 15 is rocked by the stream and releases the latter -for a further projection so that the stream will reach corner portions of the area. It will be noted that the major portions of the hills 36, are concentric with nozzle l0. Now with different pressures, and different extents of areas to be sprinkled, I provide a compensating adjustment to correspondingly vary the rocking movement of lever 15. Thus, it will be seen from Fig. 3, that rod 33, is offset at 38, so that by rotative adjustment of said rod 33, the extent ot rocking movement of lever 15, can be changed. y

In some cases, it may not be desired to sprinkle a square area although it is desired t( take full advantage ot the functions of deflection, in which case,I provide the tollowing means.

lThe rod 33,l mayv beeitherl removed or j i adjusted upwardly out vof lrange ofthe cam V so that it will not be actuated thereby. fA

screw 39, threaded. through lever 15,. atl the 7 right of pivot 16, viewing Fig.'2, impinges on the base 40, so as to hold lever 15 in the desired stream deflecting adjustment so that" the nozzle 10 will revolve' and sprinkle a circular area, the stream having the lsame` spread and projection atl all times. Of course, when the cam rod is active,.scre\v 39, will be adjusted high enough not to contactk withl base 40 and thereby interfere vwith actuation of the lever. 1 5 bythe cam.

I will next describe the novel means for localizing the stream on ay single area there# by converting 'the rotary sprinkler into. a

st ation ary sprinkler.

The cam has interior cavities 41, there bein'g shown, four in all. The nozzle 10 is provided with a lug 42 which carries a stop rod 43, .the 5 latter being loosely 1 hooked through the lug. 42. as clearly shown. Rotation of the nozzle is always in the directionl41, ,as shown in Fig. 1, and this adjustment would prevent rotation of. the nozzle. the ball idlytraversing the hollow-basel.

In Fig. 6, I have diagrammatically shown a square area 45, with the main stream 46 v projecting to one of the Vshorter radial limits of the area. This plan view shows lthe spread of the main-stream, as a result of deflection, and in Fig. 8, I have indicated the manner vin which the stream is arched.

' It'will be noted thatthe vales 37, lineup with the corners 47, of the area. Nowas the stream 46 approaches a corner, therod 33 will gradually recede into a vale 37, thereby permitting lever 15 to be rocked 4by the stream so as to release the latter -to a higher arch and a greater extent of projec.-

tion. However, this releasing action is not suicient to eliminate iiattening the streams lease the same.

In Fig. 7, I have diagrammatically shown the main stream in side elevation, the spread of drop -from the outermostto the innermost limits being indicated 48 and `49, respectively, due to deflection of the stream by lever 15. Now it will be clear that such a spread of water Iwould .leave the radially innermost area from 49to 50, comparatively dry, except tor the falling mist.` Hence the'lateral streams El. make up vthis defiarch, entirely but only to veryslightly-re-l ciency aud thmoughla' irrigate the radially innermost area not only `nbecause .theyl run -ing m-eans 39, effective.

constantly, but also because they rotate at a, much less rate of speed by reasonof their nearer proximity to the sprinkler. Thus,

springs in connection with holding or rock-V ing lever 15, the latter being reacted upon by the Water, to renderv the cam and adjust- It is believed that my invention will be fully understood from the foregoin description, and while I have herein siovvn and described one form of my invention, I

do not wish to be limited theret0exceptj -tor p razdial half beingsprin led, and said desuch limitations as the claims may import.' I claim 1. In a sprinkler, a base having a nozzle revoluble about a substantially vertical axis and having a nozzle portion inclined to the' vertical, a stream defiecting lever pivotally mounted on the top of said nozzle above said nozzle portion to rock about a substantially horizontal axis and revolve with said nozzle, said lever having a stream deflecting end overhanging said' nozzle portion on one side of the pivotal mounting of said. leven,

and said lever having an actuating end overhanging said base on another side of said pivotalV mounting of said lever, a' ltollovver rod having its upper end xed to the actuating end of said lever and said rod depend'-v vertically therefrom, and

ing substantially having hills and vales 1n a cam on said base thev path of the lovver end of said follower rod to rock said lever and alter the character of stream discharged by said nozzl portion as said nozzle revolves.l l

2.' In a sprinkling devicevfor'sp'rinkling a square area, a base, a sprinkling nozzle rotatable on said base, stream ydeflecting means on said nozzle and `rotatable therewith, a cam on said' base and havin hills and vales, and means ony said deecting means cooperating with said cam for actuating said deflecting means to seriall releaseand restrict the stream in a pre eterrnined manner to a square area when said base is located with respect tol said area to dispose the hills and vales of said cam in determined relation to said area. v 3. Ina sprinkler, a base, a, nozzle rotata able on said base for directing a main stream, a stream deflecting lever mounted on said nozzle and' having a lmain stream. deflect-ing end for flattening the arch of the' streamto distribute the Water'of they main stream over substantialll all of the outer fleeting end having a stream deiecting notch l a rounded edge for spreading the main stream, said face having a transversely disposed groove opening 'at the edges of said t'acefor deiecting lateral streamsvfrom the `main stream, and means for varying the action of said groove or rendering said groove ineffective. l

In testimony that I claim the foregoing as myown, I hereby aix my signature,
