invention, such as will enable others skilledin the art to which it appertains to make and use the same, reference being had to the accompanying drawings, ters of reference marked thereon, which form a part of this specification.

Our invention relates to improvements in lawn sprinklers, in which but two sprinkler arms are employed, the said arms being arranged adjacent each other and parallel for a short distance, then curved away from each other, and finally curved toward each other at their outer extremities, adapted to oscillate in unison and operate alternately instead of simultaneously. Adjustable fingers are mounted upon the stationary stem of the device which coperate with a valve member located in a casing, the latter having horizontally disposed sprinklin arms projecting therefrom and being rigi ly connected with a sleeve rotatably mounted u on the said stationary stem, whereby w en water is introduced, the valve is reciprocated to direct the stream of one sprinkler arm then shut it off from that arm` and direct the stream through the other sprinkler arm, thus rotating the said sleeve back and forth and producing an oscillating movement to the sprinkler arms and valve mechanism.

An important feature` of our invention lies in the fact that the adjustable fingers can be set so that the sprinkler arm and valve mechanism can oscillate in an arc of any redetermined length, said arc having a ra ius equal to the distance from the center of the stationary stem to the outer extremities of the sprinkler arms. It must, of course, be understood that the water can be discharged from the extremities of the sprinkler arms in a corresponding arc of and to the charac- 'on an enlarged scale.

both arms much greater radius, depending entirely upon the form of defiectors or nozzles employed.

Having briefly outlined our improved construction, we will proceed to describe the same in detail, reference being made to the accompanying drawing, in which is illustrated an embodiment thereof.

In this drawing,-Figure 1 is a top plan view of the device, showing one adjustment of the fingers and the sprinkling mechanism at its opposite extremities of travel. Fig. 2 is a section taken on the line 2-2, Fig. 1, looking in the direction of the arrow, but Fig. 3 is a section 2, looking in taken on the line 33, Fi

ig. 4 is an end the direction of the arrow. view of a nozzle and dei-lector, looking in the direction of arrow 4, Fig. 1, said nozzle and deector being mounted upon the outer extremity of each sprinkler arm, the said deflector shown in full lines above the nozzle and in dotted lines below the same.

The same reference characters indicate the same parts in all the views.

Let the numeral 5 designate a supporting bracket comprising a plate 6 and depending members 7 Formed integral with the plate 6 and projecting above and below the same, is a hollow elbow 8, the said elbow being curved`laterally below the plate as shown at 9 and its outer extremity threaded to receive a swivel nut 10, which in turn is connected with a. hose 11 for supplying water thereto. The portion 12 of the elbow above the late 6 is perpendicular and offset invwar ly a short distance above said plate,

said offset part being exteriorly threaded to receive the lower extremity of a stem 13, which extremity is interiorly threaded for this purpose. The stem 13 is stationary and has an inwardly offset portion 14, said offset portion having a passage 4 therethrough, which registers with the opening through the hollow elbow 8. An interior shoulder 15 and an exterior shoulder 16 are formed by the offset portion 14. A washer 17 is located between the interior shoulder 15 and the upper extremity of the elbow portion 12, whereb a water-tight joint 1s formed. Upon the exterior shoulder 16 and surrounding the offset portion 14 of the stem 13, is

of the o set portion 24, whereby mounted a casing 18 adapted to rotate thereon. The central portion of the casing 18 is enlarged at 19 to form an annular chamber 20, which is in communication with the interior of the stem 13 by means of openings 21 formed in the offset portion 14 of said stem.

Above and below the enlargement 19, the casing 18 is provided interiorly with circumferential grooves 22 and 23, which are filled with suitable packing material to form a Water tight joint between the casing and the stationary stem. The upper extremity of the stem 13 is formed solid and has au in# wardly offset projection 24 forming a shoulder 25 slightlyabove the upper extremity of the casing 18, whereby the manipulation of the thumb nut 29, hereinafter described, will not Vhinder the casing 18 from rotating upon the stem. The exterior of the oset portion 24 is smooth for a short distance above the shoulder 25, and then exteriorlyl threaded for the rest of its distance. Surrounding a part of this smooth portion and adjacent the shoulder 25, is placed a washer 26. Mounted above the washer 26 are two fingers 27 and 28 provided with perforations at their inner extremities and ada ted to fit loosely one above the other aroun' the remaining portion of the smooth surface and a sli ht portion of the threaded surface they may be turned to any desired position. The thumb nut 29 is screwed upon the threaded extremity of the stem 13, and is adapted to lock the fingers in the desired position. The enlarged portion 19 of the casing 18 is provided with an opening 30 whose wall is threaded to receive the inner extremity 31 of a valve casing 32, said extremity being exteriorly threaded for this purpose, and having a assage 33 therethrough, one extremity o which opens into the chamber 20. The opposite extremity of the passage 32 opens into a chamber 34 located in the valve casing 32. The chamber 34 is in communication with a cylindrical chamber 35 located in the forward portion of the valve casing 32, by means of openings 36 and 37, the opposite ends of the chamber 35 protruding beyond the end Walls of the chamber 34 as disclosed at 38 and 39, and having caps 40 and 41 respectively applied thereto, the caps having perforations therein as shown at 42 and 43. A cylindrical valve member 44 provided with two passages 64 and 65 is fitted in the chamber 35 and adapted to reciprocate therein, the said valve member being of suitable length for this purpose. The valve casing 32 is provided with openings 47 and 48 having forwardly projecting interiorly threaded collars 49 and 50 respectively, surrounding the same.

The inner extremity of a hollow sprinkler arm 51 is threaded into the collar 49 and the inner extremit of a second sprinkler arm 52 is threadedy arms project horizontally therefrom and are approximately parallel to each other for a short distance, then curved away from each other, and finally curved toward each other at their outer extremities, the said extremities having nozzles 53 applied thereto and each nozzle provided with a perforation 54 eccentricall arranged in their outer extremities. eiectors 55 and 56 are adjustably mounted upon the arms 50 and 51, respectivel in the rear of the nozzles by means of lips 57 bent around said arms and the said defiectors extend forwardly beyond the outer extremities of the said nozzles and are bent as shown at 58 in such a manner that when the deflectors are arranged under the nozzles, these bent extremities will extend above the perforations 54, thus directing the stream of water upwardly, While, when the said deflectors are arranged above the nozzles, the bent extremities will terminate above the said erforations and not obstruct the Water. rlghis construction is best illustrated in Fig. 4.

The central portion of the valve member 44 is provided with an upwardly projecting pin 59 extending through and above an elongated slot 60 formed in the top of thevalve casing 32. This pin is adapted to be engaged by the outer extremities of the fingers 27 and 28, which are fashioned as shown at 61 for this purpose to reciprocate the valve member 44 back and forth in the chamber 35, thereby moving the valve passage 64 from alinement with the opening 37 and the hollow sprinkler arm 51, and moving the valve passage 65 into alinement with the opening 36 and the hollow sprinkler arm 52, or vice versa, as disclosed in Fig. 3.

The side of the casing 18 opposite the opening 30 is provided with a projection 62 having a weight 63 mounted upon its outer extremity to counterbalance the weight of the valve casing and sprinkler arms.

In view of the foregoing description, the operation of our improved device will be readily understood. If the fingers 27 and 28 are adjusted as disclosed in Fig. 1, the

.water will flow'from the hose 11 into the elbow 8 upward through the stationary stem 13 through the openings 21 in said stem, into the chamber 20 formed in the rotatable casing 18. From the chamber 20 the water will How through the passage 33 of the valve casing into the chamber 34 through the opening 36, the valve passage 65, opening 48, through the sprinkler arm 52 and out of its nozzle 53, thereby causing the casing 18 to rotate upon the stationary stem 13 and the sprinkler arms to move from the full line position in Fig. 1 through an arc disclosed by the dotted lines in said figure, in the direction of the arrow A. When the into the collar 50. TheseY sprinkler arms and valve mechanism have reached the dotted line position in Fig. 1, the pin 59 will strike the finger 27 and the valve member 44 will be moved from the dotted line position in Fig. 3 to the full line position in said figure, whereby the water will then flow froln the chamber 34 through the opening 37, the valve passage 64, the sprinkler arm 51 and out of its nozzle 53, whereby the casing 18 is rotated in the reverse direction and the sprinkler arm and valve mechanism travel back through the are just described, the weight 63 at all times counterbalancing the device and preventing the casing 18 from binding upon the stationary stem 13.
