This invention relates to a sprinkler particularly applicable to large' commercial, 111- stallations such as -or'chards,'vineyards, truck gardens, and the like.

An object of my invention is to provide a sprinkler which will effectively cover a large 15 fective means of breaking up the stream of water passing out of one of the nozzles,so that it is distributed in a uniform manner close to the sprinkler itself. i

A further object is said bearing including a novel means of pre venting the accumulation ofsand therein;

Other objects, advantages and featuresof invention may appear from the accompanying drawings, the subjoineddetailed description and the appended claims. a

In the drawings Figure 1 is'a side elevation of my sprinkler.

Figure 2 1s a s1de elevation of the dispei a 30 sion element.

Figure 3 is a fragmentary, longitudinal, sectional view of one of the'nozzles.

Figure 4: is a sectional View taken on line 44 Figure 3. i Figure 5 "s a sectional View of the sprinkler body. 1

Referring more particularly to the'drawings, the numeral 1 indicates a stand-pipe upon which my sprinkler is mounted.- A coupling 2 screws on to the topof the stand pipe. A journal pipe 3 screws into the cou pling 2 and extends into thesprinkler. A;

On the p'late 19,1 'prowidea plurality of upstanding dispersion vanes consisting of'one long vane 20 which passes through the stream of water projecting from the tip 1 1 and breaks up this stream so that the water is thrown closely about the sprinkler. A driving vane21 is placed atright'angles to the stream of water from the nozzle 14: when the vane 20 is just entering that stream, thus forcing-the vane through the stream to effectively break up said stream. A rotating vane 22 extends in an opposite direction from the vane 21, and serves to. throw the plate 19 around so i that the larger vane 20 is againfbroiig lit into position as'sho'wn' in Figure 1". "Thereactance of the plate and the vanes creates a rotating-force,
