' This invention relates to improvements in the irrigating artand particularly with sprinklers used in connection" with portable,

underground and overhead and like irrigat' ing systems for all purposes. I

In a sprinkler used in these types of irrigating systems, it is essential that as' l arge' a radius of distribution of" th'e'wate'r as possible be had from the stand pipe, and also it is imperative that there be an even distribution of the water for the entire radius covered in order tom'ost econom'icallv and efiiciently carryout the irrigating processes. To th s end it has ordinarily been the practice to provide a sprinkler with one or more outlet nozzles arranged to prodiice' as great a throw as possible and tocover the complete circle of movement, means beingprovided to slowlv rotate tlie'sprinkler; the slower the rotation the more efficiently the water is distributed Heret'ofore, howev r, this mechanism hasbeeii moreior' less complicated and costly to operate and maintain;

It is the object of the presentinvention therefore to produce a 'sprinkler which is simple, cheap andjdurable andwhicltwilh cover as great or greatei' an area than-any" of the costly and complicated sprinklers now commonly in use; and one which wili reduce thecost of overhead installation to a minimum and yet give better results" than the other sprinklers noted.

These objects I accomplish by means or such structure and relatlve' arrangement of characters of reference on the drawings, the

numeral 1 designates the base coupling ar ranged for connection with the stand'pipe and provided with a. swivel cup 2 in its upper end. The numeral 3 designates the swivel or rotating pipe of the sprinkler head which projects into the swivel cup 2 and is provided at its lower end with an annular flange 4; to seat against the bottom of the cup 2. A swivel plug 5 screws into the cup 2, and there is a washer 6 of leather or the like interposed between the flange 4. and the plug 5 so that'when the sprinkler head is under the pressure of the water pass, ing therethrough there" is no metal to metal bearings, and a perfectlytight joint is as sur'ed 'to prevent the ingress of dirt or the like and the egress of water.

The swivel plug 5 is-in the form of a short cylindricalbody which fits closely around the pipe 3 for the full length ofs'aid p'ipe so as'to form an extending bearing for the pipe and thusprevent it from cant'ing or bind ing with" the rotation of the sprinkler head.

At the upper end of the pipe isthe coupling head 7 connected with which isfltlie primary outlet nozzle pipe 8 connected into the coupling 7 in direct central aliiienient with the vertical axistliereof'. bent at a substantial angle of 30'sdegrees. from the vertical, and provided with the discharge nozzle '9 at its outer endi The numeral 10 designates the. secondary dischange nozzle pipe which connects new the head 7 at substantially right angles thereto; and is provided at its? outer end" with a'discharge nozzle 11 mounted adjacent wh'ich'iis a bracket 12' having a projecting arm'1 3, on the outer end of which is a bearing sleeve 14.

A small shaft 15 projects through'the bear ing sleeve 14'. and on one end thereof is mounted asmall propeller 16 similar to an aeroplane'propeller in shap'e;and on the op posite end of the shaft 15 is a; siriallovershot water wheel 1'? mounted in the'path ofthe water to be discharged throug'lrtheiioz zle 11'. The blades or'paddles of the water wheell'l'have quitean abrupt. bevel as at 18; so as to scatter the wa ter discharge'd thereagainst .in' a" well distributed manner and alsoto set up a vibrationrelativeto'the water wheel 17 and the propeller 16 so as to thoroughly distribute it inside of the circle around the stand pipe. With the parts p0- sit-ioned as shown in Fig. Qthere will be a reactive efi'ectexerted by the issuing water on the nozzle 11 tending to move the arm 10 in a clockwise direction. The impact of the stream against the blades 18. however. will to some small extent neutralize this reactive effect. However, the driving of the propeller through the action of the wheel 17 will co-operate with the re-active ettcct of the issuing stream to drive the arm 10 and connected parts ina clockwise direction.

The vibration set up by the impact of the Water against the wheel 17 keeps the rotating head from binding in its hearmgs under the pressureof the water thereagainst and thus acilitates the rotating action, The speed of rotationis controlled by the angle at which the secondary nozzle is placed. The farther itis placed. to the left the greater will be the speed of rotation of the sprinkler headin a clock-wise,manner and vice versa as it is turned tothe right the speed will be slowed down. i t i It will. be seen from the description at the foregoing sprinkler that hile it very simple and inexpensive to manutacture.

inainta-in andoperate. nevertheless it is capable of performing the full functions for which a sprinkler ofthis type isdcsignml. namely, to throw the water to the greatest possible radius and to thoroughly discharge it over theentire area to be irrigated, doing all that the more expensive,complicated sprinklers now on the market can he pected to do.

readilyseen .thatI have produced such a de vice as substantiallyfulfills the objects of i the invention as set forth herein.

cure byLetters Patent is;

While thisspecification sets forth in detail the present and preferred constructitm of the device, still in practice such deviations from such detail may be resorted to as do not form a departure from the spirit of: the invention, as defined. by the appended claims. .Havmg thus ClQSCIIlJEd my invention what 1 claim as new and useful and closure to sel. A sprinkler comprising a rotatable head, discharge nozzles. arranged on the head, a propeller supported by the head, the propeller having a horizontal axls set at a tangent to an imaginary circle hav ng as its center a point in the vertical axis of the a secondary discharge nozzleat its outer end.

From the foregoingdescription it will he head, and means to impart rotation to the propeller whereby the action of the same against the air will tend to rotate the head.

2. A sprinker con'iprising a rotatable head including a primary d1scharge nozzle, a

pipe projecting from the head at an angle to the primary discharge nozzle and having a propeller jOIll'lltllt-ltltll? the end of the proprojecting from the head at anangle to tha primary discharge rmzzleand having a secondary dischargenozzleat ts outer end, a propeller journaled at the end ot. the; projecting pipe, the propeller havinga llOllZOll.

tal axis set at a tangentto an imaginm'v circle having as its ceut-cr a point in the var-f tical axis ofthe head, and means for driving the plOP-Elll through the medium of the is suing stream of Water from the secondary nozzle, whereby the action of the propeller on the air will tend to rotate the head. p

4. A sprinkler comprising a rotatable head including a primary discharge nozzle, a pipe projecting from the head at an angle to the. primary dischargenozzle and having a secondary discharge nozzle at itsouter end, a bracket fixed at the outer end of the pipe... a horizontal shaft journaled in the bracket at a tangent to an imaginary circle having as its center a point in the vertical axis ot the head, an overshot Water wheelfixed to one end of the shaft, and a propeller fixed to the opposite end of the shaft, the :secomlarv nozzle being arranged to discharge Water against the water wheel to drive the pro peller shaft. a
