1954 J. K. LIVINGSTON PORTABLE SPRINKLING DEVICE Filed June 18, 1952 J, K. Lglqdn gsbon INVENTOR ATTORNEYS United States Patent PORTABLE SPRINKLING DEVICE Jay K. Livingston, Houston, Tex.

Application June 18, 1952, Serial No. 294,139

1 Claim. (Cl. 299-48) This invention relates to a lawn sprinkler and has for its primary object to water a selected area of narrow and elongated or extensive areas, as between buildings and street, between walkways, or as a matter of fact at any place wherein it is desirable to water narrow lanes.

Another important object of the invention is to provide means for watering narrow or extensive areas, confining the water to the narrow or extensive areas eliminating waste of water.

Another object is to facilitate the easy transportation of the sprinkler over a surface without requiring the dis continuance of the sprinkling operation.

A further object is to maintain the sprinkler in an upright position at all times and to enable it to readily ride over obstacles, up terraces and the like while remaining upright.

The above and other objects may be attained by employing this invention which embodies among its features a hollow body which is circular in plan and has an elliptical side wall which merges into a flat circular top and a flat circular bottom, said side wall having annular rows of circumferentially spaced openings extending through the portion thereof which lies between the circular top and the equatorial portion of said side wall, means for connecting the body to a source of water pressure, and the means for selectively regulating the issue of water from certain of the openings in the side wall.

Other features include a closed bottom portion in which water passing through the sprinkler is retained in order to weight the sprinkler and hold it in upright position.

Still other features include means for coupling a flexible member to the sprinkler diametrically opposite the Water supply to facilitate the movement of the sprinkler from one location to another.

In the drawings,

Figure 1 is a plan view of a lawn sprinkler embodying the features of this invention.

Fig. 2 is a side view of the sprinkler illustrated in Figure Fig. 3 is a transverse sectional view taken substantially on the line 3--3 of Figure 1.

Fig. 4 is an enlarged fragmentary sectional view taken substantially on the line 44 of Figure 2.

Referring to the drawings in detail the sprinkler comprises a hollow body designated generally which comprises a substantially fiat bottom of circular plan 12 and a similar flat top 14 which are joined by the circumferentially extending elliptical side wall 16. As illustrated in the drawings, the entire sprinkler 10 is circular in plan, and formed in the elliptical side wall 16 adjacent its junction with the bottom 12 is an opening 18 into which is soldered or otherwise secured a tubular nipple 20 carrying at its end remote from the sprinkler 10 a suitable hose coupling 22 to which a flexible hose is detachably coupled for supplying water to the interior of sprinkler. Carried by and extending outwardly from the side wall 16 below the equatorial portion thereof is a ring 24 to which a flexible member such as a rope or cable R is adapted to be connected.

Formed in the side wall 16 between the top 14 and the equatorial portion of the side wall are annular rows 26, 28, 30 and 32 of openings through which water admitted to the interior of the body passes in the forms of jets when the device is in use. It will thus be seen that when the sprinkler is connected through the medium of the hose to a source of water supply, the water flowing through the hose will enter the interior of the sprinkler to fill it and issue in the form of jets through the passages or openings 26, 28, 30 and 32 to sprinkle an area of a lawn or the like.

The structure so far described is capable of being used in the manner previously disclosed and may be moved by exerting pull on the hose or rope R to selective positions and owing to the fact that the device is filled with water, it will readily ride over level or inclined surfaces or obstructions, without tipping over.

In order to diminish the spread of water jets leaving the sprinkler, I provide on opposite sides of the rows 32 of openings, grooves 34 in which are received annular ribs 36 carried by an annular band 38 which is mounted within the body of the sprinkler to move in an arcuate path about vertical axis of the body. The band 38 is provided at spaced intervals with openings 40 which are adapted to be moved into registration openings 32 in the wall 16, and formed at spaced intervals in the wall 16 between the grooves 34 are elongated slots 42 through which are extended the shanks 44 of rivets designated generally 46 which extend through the band 38 and carry on their outer ends heads 48 by means of which the band 38 may be shifted to move the openings 4-0 into and out of registration with the openings 32. It will thus be seen that by shifting the band 38 the passage of water through the openings 32 may be selectively arrested so as to reduce the area covered by the sprinkler.

Obviously, owing to the weight of the water within the sprinkler, the sprinkler may be readily moved from one position to another by exerting pull either on the rope or cable R or on the hose without danger of tipping over, and when the sprinkling operation has been completed, and the hose disconnected from the coupling 22, the water remaining in the sprinkler will be discharged through the nipple 20 so that the sprinkler may be easily transported.

While in the foregoing there has been shown and described the preferred embodiment of this invention it is to be understood that minor changes in the details of construction, combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as claimed.

What is claimed is:

A lawn sprinkler comprising a hollow body circular in plan and having an elliptical side wall which merges into a flat circular bottom on which the hollow body rests and a fiat circular top, said side wall having spaced circular rows of circumferentially spaced openings extending through the portion thereof which lies between the circular top and the equatorial portion of said side wall, an elongated tubular nipple carried by and extending outwardly from the side wall adjacent its junction with the bottom and communicating with the interior of the body, a hose coupling carried by the nipple through which water is introduced into the body to weight it and pass through the openings in the form of upwardly projected jets, said body having annular grooves therein which open thereinto on opposite sides of the row of openings adjacent the equatorial portion of the side wall thereof, a perforated ring-shaped valve mounted between the grooves for movement in an arcuate path for closing the openings in said row, annular ribs carried by the valve adjacent opposite side edges thereof for entering the grooves and guiding the valve, a knob carried by the valve and projecting outwardly therefrom through the body for moving the valve in its arcuate path to open or close the openings, and a ring carried by the side of the body on the side thereof remote from the nipple.
