41 Claims.-

My invention relates to adjustable sprinklers and moreparticularly to a nozzle construction for such device.

The desirability of means for adjusting the spray of water sprinklers has long been recogniz d and is evidenced by the prior art in' this field. Numerous sprinklers of this type have here. tofore been manufactured: which permit adjustment of the spray from a fine'mist to large droplets of water. However, in. addition to adjustability of the quality. ortypesof spray, it is proposed to provide meansfor varying the direction ofa spray. from such devices. That is to say; in

most instances a high spray whichcovers a large area of ground is desired, but under: somecone ditions, such as water under small: trees and bu hes, a low directed spray" is most suitable.

It is thereforean object of the present invention to provide a water sprinkler having means for adjusting the'direction aswell as the quality of the spray produced. Another object is the provision of a nozzle whichaccomplishes this result which is simple in both construction and operation.

Fi ure- 9 illustrates the operation of a Water sprinkler of my-inven-tion.

Referring now. to Figure- 1' itwill be seen that a rotor type sprinkler is-shown having a base I I, a hose coupling- I2, a body IS, a vertical member i and tubular arms-I5 mounted to rotate freely above member It. Water enters the body I3 at the hose coupling I2, passes through the vertical member M to the arms I 5 from which it is angularly discharged to impart a rotating motion to said arms i 5. Since the details of construction of this type of sprinkler are generally known further description is believed to be unnecessary.

The principal ieatures of my invention reside in the nozzle construction provided at the ends of arms !5-. Into the discharge end of arms I5 are press fitted inserts it shown in Figures 5 and 6 having an annular groove IT and circular longitudinal passages I8 and. I2; The centers of said passages-are. preferably located within one of the lower quadrantsdefined by a horizontal and vertical line. through the center on the end face of said insert. I 6. Thereason therefore will bepresently explained.- As best shown in Figures 2 and 4, caps 20',,fitted over the end of armsIS; serve as nozzlesfor the spray. Said caps havea conical end portion 21., a knurled, portion 22, and an an- On the inside of said cap, the body 24 is adapted to. seat against the outer face of. insert-I 6.and isprovidedwith an angularly disposed orifice 25 which is adapted to cooperate with either ofsaidpassages I8 and. I9 when said cap is. rotated The. cap may also be rotated; to apositionwhere orifice 25is aligned with neither of. said passages toshutoff the discharge-from the nozzle...

Inorder to permitrotationof said cap 20 and yet firmly retain it.against the face of insert IS',

the flange 23 is indented at. 21. after. assembly to cooperate withthe annular groove I'i. on. the. insert I6. Theindenting pressure is controlled so that the cap. may be. rotated. by grasping, it at the knurled section 22 and yet is suflicient to provide a. relatively. leak-proof] connection between said cap and arm I5; To facilitate adjustment of. cap 20. suitable markings. are impressed on arm I5 an'dfiange 23 as. at28 and 29. respectively to indicate the relative position of said cap on, arm I5 when orifice 25. is aligned with passages I8 and I9.

It will thus be. seen thatlwhencap 20. is rotated to a. positionwhere orifice 25 is aligned. with passage. I8. a low spray willbedirectedfrom the nozzle and when orifice 2.5. cooperates with pas.- sage. I 9 ahigh spray will be. produced. Likewise, when. orifice. 25. is. in. complete. alignment. with either passage. I8. or I9 a heavy spray is obtained which canbe reduced to a fine or highly dis.- persed spray-by rotation of cap Zflso. that. the orifice 25.is slightly out of alignment witheither one. of said passages. I8 or I9.

By locating passages I8 and I9 in the same lower quadrant, asdescribedabova. capswzt may be adjusted so that a high spray will be produced byone nozzle and a low spray by the other,

as shown in Figure 9, and, at the same time, the impulse pressure on each nozzle will produce the j same direction of rotation of all armsl5. In the modified form of construction shown in Figures In this instance the tion in the same quadrant and therefore best results are obtained when both nozzles are adjusted to the same elevation.

To obtain a spray of greater intensity either nozzle may be rotated to shut off completely the spray therefrom. With this type of adjustment discharge of a high or low spray will continue at the other nozzle but with greater force and volume. This permits sprinkling at greater distances without movement of the sprinkler.

Thus it will be seen that the nozzle construcion herein described is simple in both construction and operation and the provision of selective water passages permits adjustment of the water spray in both quality and direction.

What is claimed is as follows:

1. A nozzle construction for a water sprinkler of the type having tubular arm members mounted to rotate freely on a water receiving body comprising plugs press fitted into the discharge ends of said tubular members, said plugs having a plurality of outlet openings in the outer end face thereof for the discharge of water therethrough, said openings being spaced eccentrically of the axis of said tubular members, and a head memher for controlling the discharge of water from said outlet openings, said head having a sleeve portion telescoped over the outer surface of said tubular member at the discharge end thereof and openings in said plug member to discharge water from said head at variable angles of elevation relative to the plane of rotation of said tubular members, and means for retaining said head member at the discharge end of said tubular member with said inner face of said body memher in coplanar engagement with the outer end face of said plug.

2. A nozzle construction for a sprinkler of the type having tubular arm members mounted to rotate freely on a water receiving body comprising plugs press fitted into the discharge ends of said tubular members, each of said plugs having an outer end face and a plurality of passages therethrough terminating in a plurality of offcenter, vertically spaced outlet openings in said end face, and head members for controlling the discharge from said outlet openings, each of said head members having a sleeve portion telescoped over the discharge end of one of said tubular members and a cap portion having an inner face in coplanar engagement with said end face of one of said plugs, said sleeve being annularly indented to cooperate with an annular groove adjacent the end of said tubular member for rotatably retaining said head on the end of said tubular member, said cap portion having a passage extending therethrough obliquely to the axis of the tubular member on which it is supported and terminating in an orifice at said inner face which, when said head is rotated, is adapted to be brought into registry with any of said outlet openings whereby the water in said tubular members may be discharged at variable angles of elevation relative to the plane of rotation of said tubular members.

3. A nozzle construction for a water sprinkling device of the type having tubular arm members mounted to rotate freely on a water receiving body comprising plugs press fitted into the discharge ends of said tubular members, each of said plugs having an outer end face and a plurality of discharge passages therethrough terminating in a plurality of eccentrically disposed and vertically spaced outlet openings in said face, and head members rotatably secured at the discharge ends of each of said tubular members for controlling the discharge of water from said outlet openings, each of said head members having an inner face in coplanar engagement with;

said end face of one of said plugs and having a discharge passage therethrough, said discharge passage extending obliquely to the axis of the tubular member on which the head is supported and terminating at the inner face of said head in an'off-center orifice which is adapted to be brought into and out of registry with any of said outlet openings in said plug and into partial registry with any of said openings and out of registry with all of said outlet openings whereby the water in said tubular members may be discharged from the ends thereof as a low spray when said orifice is brought into registry with one of said outlet openings, as a high spray when brought into registry with another of said outlet openings or as a highly dispersed spray when in partial registry with one of said openings and whereby the discharge may be prevented altogether by rotating said head so that said orifice is out of registry with all of said outlet openings.

4. The combination set forth in claim 3 wherein the outlet openings on each of said plugs are positioned relative to the axes of said tubular members such that, when said orifices on each of said heads are aligned with any of the outlet openings on said plugs, the water issuing from each of said oblique passages tends to rotate each of said tubular members in the same direction on said water receiving body.
