ADOLPH WEBER, OF DETROIT, MICHIGAN, ASSIGNOR OF ONE-HALF TO HENRY IV. ROOD, OF SAME PLACE.

ROTARY SPRINKLER.

SPECIFICATION forming part of Letters Patent No. 245,421, dated August 9, 1881.

Application filed March 8, 1881.

To all whom tt may concern Be it known that I, ADOLPI-I WEBER, of Detroit, in the county of Wayne and State of Michigan, have invented an Improvement in Rotary Sprinklers, of which the following is a specification.

The nature of my invention relates to certain new and useful improvements in the construction of what are usually denominated rotary lawn-sprinklers.

The invention consists in the peculiar construction of the various parts and their combinations and operation, as more fully hereinafter described.-

Figure l is an elevation. Fig. 2 is a horizontal section in theline z z in Fig. 1. Fig. 3 is a vertical central section.

In the accompanying drawings, which form a part of this specification, A represents the pipe, which, being connected with a suitable source of water-supply, will convey the water, which is under a suitable pressure, to the pipe B, which is provided with suitable screwthreads, a, with which it is secured to the pipe A. This pipe B is preferably slightly conical in form and in its bore, as shown, and its upper end is threaded, as shown, to engage with the threaded lower end of the flaring or bell-mouth-shaped pipe 0. The pipe B is also provided with openings 1), opposite each other, through which the water will be discharged into the chamber 0, which is formed by the outer tube, D, which is sleeved on the tube B with a tight joint at d, and also at c, and is held in place by the tube 0 when the parts are put together. The tube 1) is so titted and constructed that while the joints are water-tight, they will not interfere with the free rotation of said tube, which is provided with two branches, E, one being opposite the other, as shown. These branches are screwthreaded, to enable them to be engaged with channels it, which open into the bottom of the (No model.)

comically-shaped chambers t, which are formed within a suitably-shaped casting, F, preferably cast with the branches. The edges of these castings, as well as the upper end of the tube (J, are provided with an external thread, It, to engage with the internally-thrcaded ring-nuts 1, within each of which is secured the perforated disk m, which close the chambers, except so far as the perforations are concerned.

In practice the disks at the ends of the branches are presented in opposite directions, as shown, and nearly in a vertical position, their front faces looking slightly upward. Water under pressure being admitted through the pipe A will partially escape through the rose at top, while the balance ill escape through the openings 1) into the annular chamber c, and thence through the branches E to the chambers t and the disks m. As the wa ter leaves these disks its pressure is resisted by the atmosphere, which, reacting upon the device, compelsaa rotation, which is increased or diminished in velocity by any changes in the pressure.

What I claim as my invention i.---

1. In a rotary sprinkler, the tapering pipe B, provided with a sprinkler, O, and the tube D, fitted to the pipe B, and having screwthreaded branch pipes E, in combination with the rose-sprinkler F, provided with threaded openings at one side for screwing on said branch pipes, substantially as and for the purpose specified.

2. In a rotary sprinkler, a rose-discharge consisting of the casting F, having at one side a screwthreaded opening, and having its rim screw-threaded to receive the ring-nut l of the perforated disk m, substantially as described.

ADOLPH WEBER.
