Application filed January 3, 1922. Serial No, 526,473.

To all whom it may concern:

Be itknown that I, FINIS E. RoAoE, a citizen of the United States, and resident of Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Sprinkler Apparatus, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings forming a part of this specification.

This invention relates to sprinkling apparatus, and particularly to that type in which the nozzle is given a slow rotary motion in order that the sprinkling device may distribute the water to a comparatively large area, and in which automatically op' erating means are provided for shutting off the flowof water to the nozzle and stopping the rotation of the device at the end of any predetermined amount of rotation of the nozzle.

-One of the features of the invention is of an automatically operated valve timing device which is actuated solely by the water flowing through the sprinkler apparatus, and which. is capable of being set so as to shut off the water at the end of a desired number of revolutions or at the end of any desired of the nozzle.

Another feature of the invention is the valve in the diswhich upon closure, acts to definitely stop the flow of water from the nozzle and incidentally stops the rotation of the nozzle.

Another feature is the provision of an improved structure which permits the cut-off valve to be actuated, due to the pressure of water in the apparatus.

Other features and advantages of the invention will appear as the description of the device progresses.

In the drawings which illustrate one form of the device:

Figure 1 is a side elevation of the outside of'the complete sprinkler device;

"Figure 2 is a sectional view on the line 12 2 of Figure 1, looking upwardly;

, Figu re 3 is a cross sectional view on the 1 line-3-3 of Figure 2;

Figure lis a vertical section showing the structure of the shut-ofl valve;

re 5 is a cross section on the line 55 of Figure 4, looking in the direction of the arrows;

.move during the s fraction of a revolution Figure 6 is a section on the line 6-45 of Figure 3; and

Figure 7 is a section on the line 77 of Fi ure 3.

Similar reference characters refer to similar parts throughout the several views.

Before giving a detail description of the device, a general description of the operation of the arrangement will be given. The water under pressure enters the base af the sprinkler receptacle and acts on a spider or star wheel to cause rotation of the star wheel. The sprinkler base and receptacle are stationary in the sense that they do not one area althoug moved to sprinkle This operation is quite similar to the operation of the usual water turbine. arrie by the star wheel is a shaft provided with a worm gear which operates through reducing mechanism to cause a slow rotation of the the sprinkler may be rinkling operation in any different areas as desired.

portion of the sprinkler upon which the nozzle and related parts are mounted. The timing element of the nozzle is set by the operator grasping the nozzle and depressing it and then rotating it a fraction 0 revolutions, as de-,

lution, or a plurality of sired, thus causing a .fixed lug to trave around'in the threads of the timing device. Between the timing device which carries the nozzle and the gear mechanism previously referred to, there is a friction engagement which permits-the longitudinal and rotary movement of the timing device, but whic normally causes the timing device and nozzle to rotate with the last element of the reducing train of gearing. Now assuming that the timing device has been setas above explained, and water is flowing through the sprinkler, a gradual rotary motion of the timing device and valve of the nozzle will take place. When this timing device and the nozzle thereon have rotated a suflicient distance to cause the fixed lug to travel back to the end of the spiral groove or thread in which it was moved during the setting operation, the timing device and the shut-off valve carried thereby will be released and the water pressure within the sprinkler receptacle will cause the valve to seat and thus cut off the water from the sprinkler nozzle.

Referring now to the drawings, 10 indicates the bottom of the stationary basinlike sprinkler receptacle, which is provided. about its outer circumference with the up-' means of theserews "17,- isstanding" annular. flange Integral with:

Thus "the sleeve 37 is rotatable about the member '36, but is prevented from longitudinal movement by its flange. 38.

Slidablyand also, rotatably. arranged- .withinthe member 36 is the c linder-like member 46, Member 46 is 'provi' ed with "an enlarged head 47 at the lower end thereof, which is secured to-the cylinder 46'by means of the tie members 48 (see Figure 4) Thus it will be obvious that water under pressure in the sprinkler receptacle may pass through the spring fingers 41, then through the openings between theftie the opening through the centerof the member 46. v

' The member 46, adjacent to its upper end, is provided with the screw threads'49, which are arranged to receive cooperating screw threads on the inlet branch 50 of. a nozzle 52. The, branch'50 communicates with an angular-1y extending member 52. The member 52 is'provided with screw threads at 53, with which co-operates the screw-threaded portion 54 on the nozzle opening controlling member 55. lhe rear end of the member 55 is provided with a knurled hand-piece 56 by means of which the member rotated to .cause the enlarged portion 57 of the nozzle controlling member 55 to approach or recede from the nozzle opening 58. The member 52, at the rear of the screw-threaded portion 53, is formed with l the recess 59, within which is positioned the coil spring 60. The nozzle contr lling. mem-, ber 55 is provided with a shoulder 61 and the spring is arranged to be compressed between the shoulder 61 and the .end ofthe 1 ()0. threaded portions are kept in firm engagement by the spring 60, the leakage of water between the n'iembers past the screwthre'aded. portions is also very much reduced.

-The inlet portion 50 of the nozzle-is providod ondiametrically opposite sides with thelugs or bosses 62 and 63. An opening 64 is formed through the bOfnliilQ and substantially through the boss 63, as by drilling. 1

Slots then formed in the forward portions of the lugs 62 and 63, as by saw- These slots 64' and 65 communicate with the opening 64, which, in turn, communicates with the opening through the inlet member 50. Thus the water un er premure in the sprinkler receptacle not onlypasses l0 out through the space between the nozzle opening 58 and the adjusting member 57, of fish tail sprays pass from the openings 64' and 65, respectively. This arrangement tends to insure that the spray from the nozzle will all be directed away from the sprinkler device. Thus the user can handle the sprayer with little danger of being wet.

permit the water to pass to the nozzle, Wlll be in the position, such asindicated in Figure 4,-that is, it will be in its lower position.

The automatic shutoff and timing means will now be described. The cylinder-like member 36 is provided with the inwardly extending lug 66. vThe member 46-is provided with the screw-threaded portion 67 j and two slots 68 and 69, which are formed-- face of the member 46 and,

in the outer sur communicate with the threaded portion 67; Thus, when the member 46 is inserted from below, 36, the lug 66 may be caused to pass through the slot 68 to the screw-threaded portion 67 Then, by rotating the member 46, thelug 66 will pass around through the threads of the threaded portion 67 until the longitudinally extending slot 69 at the end of the last thread is reached. Then the member 46 may be moved upwardly into the position shown in Figure 3. In this position, 70 will engage the packing ring 43 and close the opening through to the spray nozzle. if the nozzle is grasped by the operator and forced downwardly so as to cause the'lug 66 to-engage the screw-threaded portion 67, and the associated part is then rotated in a counter-clockwise direction, the lug 66 will enter the first thread of the screw-threaded portion 67 and the screw-threaded portion may be moved around over the lug until the lug is positioned any desired fraction or. number of turns from the slot 69. As long as the lug 66 is in engagement with the screw-threaded portion 67, the member 46 will be maintained in its lowered position, such as shown in Figure 4, and water will be permitted to flow to the sprinkler nozzle.

The spring fingers. 41, carried by the sleeve 37, are arranged to frictionally engage the enlarged portion 47 carried by the control member 46. The engagement between the fingers 41 and member 47 is such that 46 may be caused to move longitudi The member 46, when in a pos1- 4 under ;,free to moveJlfngitudinally,"'i'it isobviou'e that as soonest as seen in Figure 3, into the member" turbine spider 26 will .stopthe shoulder which water may pass It will now be seen that nally or in a rotary direction by the operator, but, when freed, will be caused to ro tate with the sleeve 37. It will be remembered that the water rushing into the 70 member 46, and the nozzle .5 51 mounted thereon, will be caused toimove-in the same the nozzle-and'attached partsarerotated I manner and direction'as thelsleeve 37 As of the control member, the
