Patented Sept. l5, 1931 UNITED STATES PATENT OFFICE GUADALUPE BUELNA AND HENRI EUGENE JEREMI VACHER, OF SANTA BARBARA, CALIFORNIA SPRINKLER Application filed March 17, 1930. Serial No. 436,337.

Our invention relates to a water distributing device especially designed for use in Watering, sprinkling or irrigating cultivated or planted areas and it has particular reference to a water projecting device of the rotary type.

The prime object of the invention is to provide a sprinkler of this character from which water shall be discharged only within a defined arc of its rotative motion thereby to confine the distribution to a definite area and avoid water wastage.

Other objects will appear from the following specilication in connection with the accompanying drawings, which forms a part of this disclosure and in which Fig. 1 is a sectional elevation.

Fig. 2 is a section on line 2-2 Fig. 1, and

Fig. 3 is a section on line 3-3 Fig. 1.

In its broader aspect, our inventlon consists of a body or chamber connected with a water supply and provided with a water impelled means for imparting to said body or chamber a relatively slow rotative motion, the body or chamber being provided with water distributing nozzles and with means whereby the water entering into said chamber is alternately discharged through said nozzles only during the rotation thereof in a .o defined area. The invention is applicable also to that type of sprinkler head in which the rotation thereof is eected by the reactive eli'ect of the water discharging from the nozzles, but positive meansy for rotating the head are preferable because thereby the speed of rotation may be controlled and a more eficient wetting obtained.

In a more specic sense, and referring particularly to the form of embodiment of the device expressed in the accompanying drawings, which is a part of this disclosure, the invention comprises a hollow body or head 1, which for purposes of assembly and inspection, is preferably composed .of two sections 2 and 3 threadedly conjoined. The .section 2 is a chamber provided centrally thereof with a bored extension 2', for purposes to be stated later. The section 3, which forms a closure for the chamber or section l0 2, is provided with a housing 4, having an internal cylindrical cavity 4 that is in open communication with the section or chamber 2 to receive the water therefrom. Said housing is provided with oppositely disposed, preferably angular-ly related outlets orpipes 5 and 6, into which sprinkler nozzles 7 and 8 are arranged to be screwed. Inthe cavity 4 of the housing 4 is securely fitted a cylindrical body or sleeve 9, that is provided with relatively narrow and elongated vertical ports 10 and 11. These ports 10 and 11 respectively register or are alined with the passageways in the outlet pipes 5 and 6 and through them the water passes from chamber or section 2, eventually discharging through the sprinkler nozzles 7 and 8.

Within the chamber or section 2 is a horizontally disposed head 12, that is provided with a vertical bored extension 13, which is arranged to project through the extension 2 on the section or chamber 2 and the end of which extension 13 is threaded to receive a fitting 14, by which connection may be made with a water supply pipe 15. The head 12 is provided with a plurality of tangential 75 horizontal passageways 16 which communicate with the bore or passageway 13 in the extension 13. The passageways 16 project a plurality of jets tangentially against the inner face of an annulus 17 which surrounds said head 12; rests loosely and unconnectedly upon the bottom of the chamber or section 2 and is diametrically smaller than said chamber. The action of these jets is to rotate said annulus 17 continuously within said chamber, which, as said annulus engages one or the other of opposed indentations 18 and 19 in the wall of said chamber, is periodically moved therewith thereby producing an intermittent and relatively slow rotation of the sprinkler body.

Upon the head 12, is positioned a semicircular valve 2O which is disposed within the sleeve or cylindrical body 9 and the top of which is circular as seen at 21. By means of a spring 22, seated in a recess 23 in the top of the housing 4 and bearing upon the cir-z cular top 9 of the valve 20, the bottom of the chamber or section 2 is caused to be held in snug engagement with the bottom of the 100 water-jetting head 12, thereby insuring a water-tight metal-to-metal joint, which sand or other foreign substancescannot disturb, and obviating the need for packing. The spring 22 supports the entire sprinkler head or body 1 which is rotatable relatively to the Water jet-ting head 12. The rotative movement of said valve 20` with the 'sprinkler head 1 during operation is prevented by a pin or other device 24, which is arranged to abut against ay stop 25 provided on the waterjetting head 12. During therotation of the.

sprinkler headl 1, one or the other of the elongated vertical ports 10 and 11 will be closed by the stationary valve 20, thereby preventing any water from issuing from one of the nozzles 7 and 8, while thewater is freely projected from the other nozzle. The alternate projection ofthe water through the nozzles and the shut-olf occur during the rotation of the sprinkler head through substantially a half circle, the shutting olf of .the water from one nozzle taking place practically simultaneously with the admission of water to the other nozzle.l Y

`It will be observed that the valve 20 is ing the ports in said liner during the rotation of said chamber.

2. A sprinkler comprising a rotatable chamber provided in the top thereof with opposed outlets, sprinkler nozzles in said outlets, a water distributing head within said chamber and connected to a water supply, a valve loosely mounted upon said head, means yieldingly supporting said-.chamber from said valve and insuring a water tight joint between the bottom of said chamber and said head, and means to rotate said chamber g relatively to said valve thereby to cause the water to. be alternately discharged through saidnozzles only during approximately ahalf revolutionof said chamber.-

In testimony whereof we have set our hands.

loosely set upon the jetting head 12, that is, v

it is not connected with said head. Y The essential purpose of this arrangement is to cause a 'close and positive seating of the valve against the lining or sleeve 9 especially in the region of the ports 10 and 11 therein, this seating or contact of the valve being insured by the pressure of water against the plane surface of the valve and also by the partial vacuum created in the nozzle, the passageway of which is closedv by the valve 20.

In order to determine, when the sprinkler is assembled, 'which of the ports 10 and 11 in the lining o r sleeve 9.is closed by the valve 20, we provide an indication 26 on the tting 1-1 which is in verticalalinement With'the stop 25 on the jetting head 12. When this fitting 14 is therefore turned so that it registers with or is in line with one ofthe nozzles 7 and 8, the port in thel lining or sleeve 9.1eading to the particular nozzle 1s closed. In this wise the sprinkler may be set to irrigate the special area desired.

What we claim, is:

1. A sprinkler comprising a chamber having a housing provided with a cavity and with pipes, sprinkler nozzlestted in said pipes, a liner in said cavity provided with opposed elongated ports registering with the passageways in said pipes, a water distributing head within said chamber and connected to a water supply, a valve .loosely mounted' upon said head and disposed within said cavity, a yielding means carried by said valve to support said chamber and hold the bottom thereof in water tight engagement with said head, and means acted upon by the water issuing from said head to rotate said chamber, said valve alternately opening and clos-
