NONCLOGGING SPRAY NOZZLE.
Application filed August 21', 1926. Serial No. 130,647.
My invention relates to spray nozzles and more particularly to a non-clogging spray nozzle for cooling purposes.
It is a purpose of my invention to provide a nozzle for use in connection with spray ponds for cooling water in connection with same will not clog easily but will at the same time give a very uniform spraying action. In order to accomplish this, my i1nproved nozzle is made with all the passages these can possibly be made and still obtain etticient'spraying action. Furthermore in order to prevent clogging, the passages are made free and open without any projections into the same or any inserted parts to obtain the spraying action of the nozzle. In other words, the spraying action is obtained entirely due to the contour of the walls of the passages themselves, and the contour of these walls is smooth so as to avoid any narrow passages or protuberances into the interior of the nozzle that might collect foreign mat-- ter and clog the nozzle. It is more particularly a purpose of my invention to provide a spray nozzle wherein the spraying action is obtained by setting up a whirling action of the water within the chamber of the nozzle by introducing the stream of water into the nozzle tangentially of the wallet said" chamber and discharging thesame from a wide orifice located in a dome shaped end portion of said chamber. The inlet into said chamber is preferably in the form of a narrowmouth nozzle having walls that gradually converge toward the chamber, said walls be ing curved and being so formed that the entrance tothe inlet passage to the chamber is substantially rectangular and is elongated in the direction of'the. axis of the chamber and has the one wallthereof substantially coincident with theisidewall of the chamber sothat the streamof liquid entering the chamber enters substantially tangentially of said wall. Furthermore the main body portion'of the nozzle preferably comprises a substantially cylindrical cham her having a' straight substantially plane end wall portion and having a dome shaped end opposite the plane end wall which is provided with a central orifice that is relativel wide. The dome shaped end is preferab y spheroidal and the discharge orifice has a substantially cylindrical wall portion of uniform diameter. A
It is furthermore a purpose of my invention to provide a nozzle of the above mentioned character in which t-he'cylindrical wall portion of the chamber extends a substantial distance beyond the nearest edge of the inlet opening toward the discharge orifice, which produces a much more efiicient spraying action than would be the case if the dome shaped portion were closely adjacent said inlet opening, the elongated 'cvlindrical swirl chamber roducing a uniiiorm spraying action with t 1e wide mouthed ori. fice and making it unnecessary to provide any vanes, deflecting members, screens or other deyices to obtain a good spraying actlon.
,Other objects and advantages of the invention will appear as the description of the accompanying drawings proceeds. However, I desire to have it distinctly understgod he that I do not intend to limit myself to exact details shown or described, but that I intend to include as part of my invention all such obvious changes and modifications of:
parts as would occur toa person skilled in this art and as would fall within the scope of the claims.
In the drawings:
Fig: 1 is a perspective view of my iniproved nozzle.
Fig. 2 1s a viewpartly in longitudinal section and partly in perspective of my im proved nozzle, the section being taken substantially on the line 2- 2 of Fig. 4. L
Fig. 3 is a section taken at right angles to Fig. 2, being taken substantially on the line 3-30f Fig; 4, and
v Fig. .4 is a transverse sectional view taken at right angles to Figs. 2 and 3.
Referring in detail to the drawings:
My improved nozzle comprises theebodv port-ion 10 which is provided with a plane closed end wall floor 11 perpendicular to the axis of the body portion and a substantiallv cylindrical side wall portion 12 of uniform diameter, and a dome shaped end portion 13 which is substantially spheroidal in form and which terminates in a short neck portion 14v providing a discharge passage that has a substantially cylindrical inner face.
. Extending from one side of the body portion 10 is an inlet 15 which is provided with a polygonal outer wall portion 16 whereby a tool may be applied thereto for screwing the nozzle in place, said inlet being internally v threaded as indicated at 17, whereby the lie substantially opposite each other, and
inlet channel.
thesubstantially straight parallel top and bottom wall portions 21 and 22 forming an The curved wall portions 19 and are of such ashape as to gradually change the cross sectional shape of the opening in the member 15 from a substantially circular contour'to a. rectangular passage 23 where the inlet discharges into the chamber 24 provided in the main body portion 10.
Moreover, the curvature of the wall portions 19 and 20 is substantially convex from the circular threaded portion 17 to the rectangular portion 23, "gradually reducing the cross sectional area, of the passage so as to form a narrow-mouthed inlet into the chamber 24. with the floor of the chamber and substantially flush with the wall 11, being only slightly offset therefrom as at 25. The Wall portion21 lies substantially midway of the length'ot the nozzle, being substantially midway between the upper or outer tace26 of the discharge outlet 14. and the closed end lwall 11. The cylindrical portion of the V chamber 24 which is of substantially uniform diameter, extends from the closed wall 11 a considerable distance past the edge of the opening 23 which is nearest the discharge orifice in the portion 14 and merges into the substantially spheroidal dome shaped end portion 13 near the portion 14, the arcuate or dome-shaped inner wall portion being indicated by the numeral 27, the inner cylinvdrical side face portion by the numeral 28 and the inner cylindrical face of the orifice in the portion 14 by the numeral29. Thus the smooth cylindrical wall portion 28 merges into the dome shaped portion 27 in a gradually curved wall portion, and the arcuate or dome shaped wall portion 27 -merges wlth the cylindrical walled passage 29 of the neck portion 14. w g
It will further be noted that the side edge 30 of therectangular opening 22 coincides substantially with the cylindrical. wall portion 28 there being a slightly flattened portiori at 31 adjacent the .portion 30. The
stream of liquid passing through the open-' ing 22 thus strikes the cylindrical wall portion 28 substantially on a tangent, causing the liquid to be thrown into a whlrlmgmotion with the center of the swirl substantlally The wall 22'liesin a plane parallel Letters Patent is:
on the axis of the cylindrical portion 28. This continues as the liquid travels around the cylindrical wall portion 28 and toward the orifice in the portion'lt which orifice, it will be noted, is of large diameter, being of substantially half the diameter of the cylindrical portion 28. The travel of the liquid around the dome shaped portion 27 and up through, and due to the elongated cylindrical body portion thereof, spraying effectively in spite .of the large passages used throughout. The nozzle accordingly has a very large capacity and at the same time is highly reliable because of the factthat clogging is substantially entirely, eliminated.
What I claim and desire to secure by 1. A spray nozzle comprising a body member forming a swirl chamber of substantially cylindrical cross section for the greater portion of its depth and terminating at one end in a relatively shallow, dome having a concentric outlet port and at the other end in a plane floor substantially perpendicular to the axis of the chamber, the body having a sub stantially rectangular inlet port elongated in the direction of the axis of said chamber, and an inlet channel having parallel top and bottom walls, the inlet port being arranged to discharge tangentially to the wall of said chamber and of substantially less depth than the chamber to provide an area of unrestricted relatively circular'swirl intersecting the inlet and an area of unrestricted spiral swirl between the inlet and said dome.
2. A spray nozzlecomprising a body forming a cylindrical chamber having a plane floor at one end perpendicular to the axis of the chamber, and terminating at the other end in a relatively shallow dome having a 'lindrical chamber, the inlet channel being arranged to discharge tangentially to the wall of said "chamber.
In testimony whereof I aflix my signature.
