LAWN-SPRINKLER.

SPECIFICATION forming part of Letters Patent No. 530,620, dat d December 11, 1894.

Application filed August 1, 1894. Serial No. 519,187. (No model.)

.To all whom it may concern:

Be it known that I, THOMAS MAHER,a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Lawn-Sprinklers, of which the following is a full, clear, and exact description. a

My invention consists of a case having within it an annular chamber with an opening oroutlet at the top, a post rising from the center of the floor of said chamber, and an external extension projected from the wallof said chamber and 0d of the center, with a threaded opening therein for the attachment .of a hose, said extension opening into the inthrough the sprinkler naturally varies in ex-' tent, according to the amount of water permitted 'to enter the same and the pressure behind said water, so that a large or small surface of spray may be obtained by regulating the flow of-liquid through the hose as desired.

That my invention may beseen and fully understood by others, reference will be had to the following specification and annexed drawings forming a part thereof, in which- Figure 1 is a side view of my sprinkler;

j Fig. 2, a front view of the same Fig. 3, a vertical section on'lines x, as, Fig.0; Fig. 4, a similar section showing a modified form of post; Fig. 5, a plan View of said sprinkler, and Fig. 6, a horizontal section on lines 3 y, Fig. 1. V

Similar figures of reference designate like parts in the drawingsand specification.

The case 1 is constructed of iron, glass, porcelain, or other suitable material and consists of the flange 2, the floor 3, the cylindrical wall 4, the oval top 5, and the'extension 6.

The external shape of the case 1 mayvary from that shown in the drawings, provided Directly above representing the horizontal center of the extension considerably in advance of or remote from a parallel linepassing through the center of the chamber 7. In the forward end.

of theextension 6 is the threaded opening 10 to receive the end of a hose or other supply pipe, and said opening terminates atthe back in the contracted orifice 11, close to the tangent side of said extension.

In operation the case 1 is connected to a supply pipe by means of the extension 6, and placed on the ground in the locality which it is desired to sprinkle, the flange 2 assisting to retain said base in an upright posit-ion, or it may be held in the handto spray vines and other forms of vegetation that have a more extensive vertical growth than grass and the like. The water is turned on, enters the chamber 7 through the extension 6 with great force owing to the fact that the orificell is so much smaller than the extension opening 10, passes around said chamber in the direction of the arrows in Fig. 5, encounters the incoming stream, and then escapes through the hole 9 in the formof spray. Theimpact of the water in the chamber 7causes thesame to leave thecase l in the formof spray which spreads out. umbrella-like, limited in extent only by the force or pressure behindthe fluid. The tapering post 8 serves as a pivot around which the water passes andsaid post further directs the upward rush of the same toward the hole 9. The post 8 is not an absolutely essential member of myinvention', but better results are produced by its use. I

In Fig. 4 a modified form of the post8 is shown at 8*,in which appear the vertical passage 12 and the lateral passages 13 at or near the base of said post, opening into said vertical passage at the bottom of the same. The

post 8 is threaded at the base and screwed into a. threaded opening in. the floor 3. By

using the perforated post 8, a portion of the water entering the chamber 7 is forced into.

the passages 13 and escapes through the central passage 12 in an unbroken stream, about which the spray from the balance of said water is disseminated.

What I claim as my invention, and desire to secure by Letters Patent, is

As a new article of manufacture, a sprinkler consisting of a case having within it an annular chamber opening through the top of said case, a central post rising from the floor of said chamber and provided with lateral, basic passages opening into a vertical passage in said post, and an external extension pro- THOMAS MAHER.
