TO THE AUTOMATIC IRRIGATION COMPANY, OF MU'SKEG'ON, MICHIGAN, A. COR- PORATION OF MICHIGAN.

NOZZLE.

Application filed January 10, 1923. Serial No. 611,742.

To all whom it may concern: 7

Be it known that I, HOMER B. MARCH, a citizen of the United States, residing at Muskegon, in the county of Muskegon and State of Michigan, have invented new and useful Improvements in Nozzles, of which the following is a specification.

The present inventionrelates to nozzles, particularly such as are. employed to vent water from the horizontally disposed water pipes of an irrigating or sprinkling system; and its object is to provide such a nozzle having a deflector adapted to be bent into a set position to direct the water issuing from the nozzle in a desired direction; and further to provide an improved screen for such a nozzle whereby any solid matter in suspension in the water may be prevented from stopping or interfering with the flow of the water through the nozzle.

Ihis and any other objects hereinafter appearing are attained by, and the invention finds preferable embodiment in, the structure hereinafter particularly described in the body of this specification and illus: trated by the accompanying drawings, in which Figure 1 is a vertical central longitudinal sectional view of a portion'of an irrigating pipe, to which my improved nozzles are applied, one of which isshown incentral longitudinal section taken on line 11 of Figure 2; V

Figure 2 is an under side view of the same, one of the nozzles being shown in transverse section taken on line 22 of Figure 1, and the other nozzle being shown in transverse section taken on line 2 -2 of Figure 1;

Figure 3 is a side View (reduced in size) of said pipe illustrating nozzles whose deflectors are bent to various set positions; and

Figure 4 is a transverse sectional view of the pipe taken on line 44 of Figure 3.

In the embodiment of 'my invention chosen for illustration by the drawings and for detailed description in the body of this specification, a portion of a horizontally disposed pipe 1 through which water for irrigating or sprinkling passes. is shown, to which pipe are applied a plurality of my nozzles 52, spaced apart at desired intervals.

As thus illustrated, these nozzles are threaded into openings through the wall of the pipe. Each nozzle has a passage theresage is seated thereinand, as shown, ex-

tends outwardly beyond the inner end 6 of the nozzle and into the interior of the pipe 1, and may be secured in position by a small lump of solder 7. It will be seen that by thus rolling the screen into the involute form shown the openings in one layer of the screen are disposed at varying distances from the openings in the adjacent layer or 7 layers, so that a very perfect screening out of any solid matter suspended in the water is efl ected, and such matter is prevented from entering the vent 4 and thus stopping or interfering with the flow of the water I therethrough.

'Ihe nozzle is furnished with a deflector 8, integral therewith and extending outwardly from the body portion 9 of the noz- 'zle adjacent its vent 4. 'This defiectoror its restricted portion 10 adjacent the nozzles body portionis bendable so that the deflector may be bent into a set position as desired, in. order that the stream issuing from the vent may be directed in a desired direction. As shown, the lateral surface 11 of the deflector is cross-sectionally convex and longitudinally concave, so that the water issuing from the vent may be not only deflected by-the concavity of the deflector into the desired direction, but also spread laterally by the deflectors convexity.

In Figure 3 positions of the deflectors bent into different set positions is illustrated.

It will be readily understood that the screen may be removed from the nozzle and unrolled into flat form in which form it may be readily cleaned of clogging substances, and may then be again rolled into involuted or other cross-sectionally curved form and inserted into the nozzle; and'that any bendable foraminous sheet, whether of mesh form or not, and whether involuted or bent into other cross-sectionally curved form, may be thus removed from the nozzle, fiattened out for cleaning and again bent into such curved form and reinserted into the nozzle.

I claim: 1. In a device of the character described: a pipe having an opening through its side;

a nozzle having a passage therethrough and seated in said openin a strainer formed from a toraininous sheet rolled into a substantially coinpact roll, its adjacent convolutions contacting each other, inserted into the nozzles passage.

2. In a device 01' the character described: a pipe having an opening through its side; a nozzle having a passage therethrough and seated in said openin 'g a strainer formed from a toraminous sheet rolled into a substantially compact roll, its adjacent convolntions contacting each other, inserted into the nozzles passage and axially extending into the pipe transversely thereof.

A liquid strainer formed from a toraininous sheet rolled into a substantially compact roll, its adjacent convolutions eontacting each other, and positioned axiallytransversely t0 the flow of liquid screened thereby.

In testimony whereof I have hereunto setmy hand atGrand Rapids, Michigan, this 12th day of December, 1922.
