Application filed January 5, 1915.

To all whom it may concern. Be it known that I, EARL V. CoULsToN, a

citizen of the United States, resident of Cleveland, county of Cuy'ahoga, and State of Ohio, have invented a new and useful Improvement in Lawn-Sprinklers, of which the following is a specification, the principle of the invention being herein explained and the best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions.

My invention relates to lawn sprinklers, its object being to provide a sprinkler which may be attached to a lawn hose in the usual manner, which will operate eliiciently and which may be manufactured at a comparatively low cost.

The said invention consists of means hereinafter fully described and particularly set forth in the claims.

The annexed drawing and the following description set forth in detail certain. means embodying my invention, the disclosed means, however, constituting but one of various mechanical forms in which the principle of the invention may be applied.

In said annexed drawings :Figure 1 represents a plan of a sprinkler embodying my invention, showing a fragmentary portion of the end of a hose to which it is attached. Fig. 2 represents a vertical axial section of the parts shown in Fig. 1. Fig. 3 represents a front elevation and Fig. 4 a side elevation.

The illustrated embodiment of my invention comprises a unitary structure having three main parts, a main or body portion 1 of general cylindrical form, an end wall 2, and lateral members 3. The main or body portion 1 is provided with interior threads 4 by means of which the sprinkler may be attached to the usual nipple 5 of an ordinary lawn hose. The end wall 2 consists of three parts, a lower part 6, an upper part 7 and an intermediate part 8. The upper part 7 is substantially plane and also substantially perpendicular to the main or body portion 1 and has an interior flat surface 9. The interior surface of the lower part 6 is concave and spherical in form and its upper end terminates substantially in a horizontal plane passing through the axis of the main or body portion 1. The upper end of the lower portion 6 and the lower end of the upper portion 7 of the outer wall are connected by the flat portion 8, as shown. The

Specification of Letters Patent.

ltiay 3t), 1916.

Serial No. 5%. 1

middle ofthe upper portion 7 and intermediate or connection portion 8 are pierced by a rectangular slot 12, as shown in Figs. 1, 2 and 3.

In using the above described device, it is attached in the usual manner to the hose and water and into the sprinkler, from which it emerges through the slot 12. The. lower spherical surface 10 being substantially inclined to the axis of the sprinkler and hence inclined water, it will be seen that the lower portion of the body of the water will be deflected so as to pass upwardly through the lower part of the slot 12, as shown in dotted lines in Fig. 2. The upper portion of the body of the water, however, passes straight through the upper part of the slot 12, with the result that two opposing and converging streams are formed which meet and cause a spatulate spreading of the water, as shown in Fig. 1, whereby such water is distributed in an economical and eflicient manner. The slot and the inner adjacent surface are so arranged that the plane of the spatulate body of water will be slightly and upwardly inclined with reference to the horizontal, as shown in Fig. 2.

In order to position the device upon the ground, the main or body portion has secured thereto, two laterally extending and integral legs 13, 13, Figs. 3 and 4, which rest upon the ground and hold the device in a position in which the major dimension of the slot 12 issubstantially perpendicular.

It will be seen from the above description that a very simple sprinkler is thus obtained, which may be made with all its parts integral with each other and hence may be manufactured at a low cost.

Having fully described my invention, what I claim and desire to secure by Letters Patent is 1. As a new article of manufacture, a sprinkler having a cylindrical portion adapted to be connected with a hose, and having an end wall comprising a portion inclined with reference to the axis of said cylindrical portion, a portion substantially perpendicular to said axis, and a portion joining said perpendicular and inclined portions; said end wallbeing provided with an opening intersecting said perpendicular and joining portions.

properly to the direction of entrance of the.

permitted to pass therethrough I 2. As a new article of manufacture, a lawn sprinkler comprising a main or cylindrical portion adapted to be connected with a hose; an end wall comprising three parts, a lower part, an upper part and an intermediate or connecting part; said upper and intermediate parts being provided with an interior surface of substantia 1y spherical form.

v 3, As a new article of manufacture, a

sprinkler having a cylindrical portion adapted to be connectedwith a hose, and an end wall comprising a lower portion inclined with reference tothe axis of the cylindrical portion a portion substantially perpendicular and transverse with respect to j a slot passing therethrough; ,"said lower part having EARL 'V. COULSTON.
