SPRINKLER Filed Feb. 18, 1930 r anoento a LW. GREER Patented Dec. 2, 1930 UNITED STATES LESLIE w. GREEK, or rnonmx, ARIZONA SPRINKLER Application filed February 18, 1930. Serial No. 429,887.

This invention relates to a sprinkler or ir rigating device, particularly adapted for use in sprinkling lawns, but capable of use in any relation, such as upon'golf courses, in public parks, and the like.

It is a primary object of the invention to provide a device of very simple and inexpensivc nature, constructed in such manner as to distribute water in equal volume and density I" to square spaces or into square corners.

In the accon'lpanying drawing:

Fig. 1 is a perspective view of a sprinkler constructed in accordance with the invention,

Fig. 2 is a verticalsectional view therethrough, and 1 Fig. 3 is a fragmentary sectional view upon line 33 of Fig. 2.

Like numerals designate corresponding parts in all of the figures of the drawing.

The sprinkler of the present invention comprises a threaded base 5, to adapt it for attachment to any suitable water supply pipe. It is, preferably, provided with an angular shaped portion 6, to which a wrench or like tool may be applied. The base 5 carries a vertically elongated head 7, which is substantially square in horizontal cross section. That is to say, its fiat outer faces lie at angles of 90 with respect to each other. The inter- I!" nal bore 8 of the head 7 is also preferably square in cross section, and the flow of water therethrough may be increased or diminished by the proper setting of an adjusting screw 9. Oblique slots 1010 are cut through the walls of the head 7, from the internal boreto the opposite outer faces 1111 of the head 7, and oblique slots 12-12 are cut through the wall of the head 7, from the bore 8 thereof, to the opposite outer faces 11"11. It will be seen that by virtue of this structure the sprinkler will discharge the water in the form of a wide, flat band from each of the slots, and that there will be a slot facing in all four di- 5 rections, so that the water may be caused to cover a square plot or to be discharged up into square corners. This result is achieved by making the slots in elongated straight form, and this, in turn, is rendered possible by forming the slots in the plane faces of the head. This result could not be secured by a round head, for example.

It is to be understood that the invention is not limited to the precise arrangement shown, but that it includes within its purview whatever changes fairly come within either the terms or the spirit of the appended claims.

Having described my invention, what I claim is:

1. A sprinkler of the character described, comprising a part having an internal bore for the reception of water, and a plurality of flat outer faces, there being slots formed obliquely through the walls of said part from said bore to said flat outer faces, and extending transversely across said faces in elongated form.

2. A device of the character described, comprising a vertically elongated tubular head that is substantially square in horizontal cross section to present four flat outer faces, there being oblique slots formed in each of the walls of said head extending from the bore thereof to the outer faces thereof.

3. A structure as recited in claim 2, wherein the slots upon opposed faces of said headare in substantial alignment with each other.

4. A structure as recited in claim 2, wherein the slots upon opposed faces of said head are in substantial alignment with each other, but at a different level from the slots upon the other faces of said head.

In testimony whereof I affix my signature.
