' Specification of Letters Patent.
Application filed December 28,1906. Serial No. 349.770.
Patented Oct. 22, 1907.
To all whom it may concern:
Be it known that I, CHARLES W. SKINNER, a citizen of the United States, residing at Troy, Miami county, Ohio, have invented certain new and useful Improvements in Nozzles, of which the following is a specification.
This invention pertains to improvements in that class of nozzles designed to pioject in longitudinal series from the side of a pipe to be employed for irrigating and other sprinkling purposes calling for extremely fine jets oi' water. The improved construction will be readily understood from the following description taken in connection with the accompanying drawing in which Figure l is a side elevation of my improved nozzle, and ,Fig. 2 a vertical diametrical section of the same on a very much enlarged scale.
In the drawing:-l, indicates the body of the nor,- zle, being that portion which is to project from the exterior oi the side of a pipe: 2, the threaded shank iorming a partoi the body and adaptedto be screwed into, a threaded hole in a pipe: 3, the jet hole disposed axially in the body, this hole in practice being minute, say one-twentieth of an inch or less: 4, a counterbore in the shank'end of the body, this counterbore being as large as is consistent with the diameter of the threaded shank and extending into the body to such depth as to leave a comparatively' thin portion of the body through which the jet hole 3 extends: 5, an angular shield carried by the body over the outer end of the jet hole, this shield being formed by extending the body outwardly beyond the outer end of the jet hole and then cutting the triangular notch across the side of the body so as to expose the jet hole to the notch: 6, a tube fitted tightly into one end of the counterbore in the body and projecting some distance from the end of the threaded shank, this tube having as large a bore as is consistent with its exterior diameter: 7, a reduced inlet aperture at the outer end 'of the tube: and 8, a plurality of apertures through the side wall of the tube, the apertures 7 and 8 being preferably of diameter not materially in excess of that of the jet hole 3.
When the threaded shank is screwed tightly into a threaded hole in the side of a pipe the tube projects well inside the pipe and .presents its inlet apertures 7 and 8 at some distance from the wall of the pipe. The
consequence is-that the nozzle-is supplied with water drawn from those regions in the pipe some distance from the inwall oi the pipe, these inlets therefore acting, not only as strainers but, also, in great measure, in preventing inflow of foreign particlesjound in practice to flow in excessive degree along or near the inwall of pipes. The water entering the inlets reaches the enlarged chamber formed by the tube and by the counterbore in the body, its velocity becoming reduced, whereby there is avoided a direct violent flow of foreign matter to the minute jet hole. The shield 5 deflects the jetting stream and breaks it up into a spray, and the shield at the same time forms a protection over the jet hole so that when the nozzle is idle no foreign matter can enter the jet hole in a direct line with its axis and no foreign matter can reach the noz- 'zle at all when coming from that side on which is disposedthe shield. The shield further protects the jet and spray from the disturbing effects of wind and thus permits the spray to be more satisfactorily directed.
In making the nozzle the body is counterbored, drilled, and threaded and then cut off from cylindrical rod stock, after which the triangular notch is cut across the body. The tube is bored from solid rod stock, then cut off and drilled and driven into the counterbore of the body. I
A nozzle comprising a cylindrical body having a triangujlar notch cut across its outer end and having a counterborcd shank at its inner end and having a jet hole lendingaxially from the counter-bore into the notch, and a tube sccured in the outer end of the counterbore and projecting therefrom and having a plurality of inlet-apertures, combined substantially as set forth.
