SPRAY` NOZZLE.
Application led. June 2,
To all whom z't may concern:
Be it known that I, HERBERT W.,DAY, a citizen of thx. United States, residing at Wollaston, county of Norfolk, State of Massachusetts, have invented an Improvement in Spray Nozzles, of which the following description, in connection with 'the accompanying drawing, is a specification,-
like characters on the drawing representinglike parts. l
his mventior`l relates to spray nozzles and to'a method of spraying therewith, and has for one of its objects to provide a novel spray nozzle and novel method of spraying by which a spray of av predetermined shape will be produced which will remain constant even though the pressure under which the fluid or fluids are being delivered varies.
This invention also has for lits object to provide a novel spray nozzle.which will deliver a spray having a uniformconsistency throughout its extent so that the character of the mixture at the edge of the spray will be the same as that at the center of the spray.
Other objects of my invention are to improve spray nozzles in -various ways, all asWill be more fully hereinafter set forth.
In order to give an understanding of my invention, I have illustrated in the drawings a selected embodiment thereof which will now be described, after which 5-5 F ig. 1 andl indicating the shape of the spray.
My improved spray nozzle comprises a body portion 1 having separate chambers or spaces 2 and 3 into which the different fluids or gases to be sprayed are delivered, a head 4 having a delivery orifice 5 through which the spray is delivered from the nozzle, vand a plurality of converging ducts or passages leading from the se arate chambers 2 and 3 to the delivery ori ce 5. These ducts or passages and the delivery orifice 1919.' Serial No. 301,273.
5 have such a relation to each other that the streams issuing from the ducts or passages meet in the plane of the oritice 5. I find that by means of this construction a spray will be produced which has a predetermined cross sectional shape that does lnot vary even though the pressure under which the fluids or gases entering the chambers 2 and 3 vary.
Any number of these converging ducts or passages may be employed. In theconstruction herein shown I have provided two ducts or passages 6 which communicate with the chamber 2 and one duct or passage 7 communicating with the chamber 3. The duct or passage 7 is shown as situated axially of the nozzle, and the passages 6 are on either side of the passage 7 and converge toward the orifice 5. This arrangement of passages is however, merely used for illustrative purposes, asthe invention is not limited to any particular number of such passages. It 1s, however, important that said passages should have such relation to each other, and to the orifice 5 that the streams of fluid or gas issuing from said passages will meet in the plane of the orifice 5 or, in other words, in the plane of the dotted line 8 which is employed to indicate the plane of the orifice. The streams issuing from the passages 6 and 7 are released from the nozzle at the plane of the orifice 5, and this is the point at which they meet. My invention, therefore, provides a construction in which the various streams meet and are released from the nozzle at the same point. By having these various streams meet at a common point in the plane of the orifice through which they are released from the nozzle, I lind that the spray projected from the nozzle will have a form determined by the projection of the axes of the several streams of fiuid beyond their common point of intersection, and that said spray will be bounded by a surface formed by the continuation beyond the orifice of the outer side of the wall of each of the intersecting ducts or-passages, and by outer side as used above I mean that side of each duct or passage situated furthest from thel central axis of the spray.
A spray thus produced will have a crosssectional shape similar to the shape of the delivery orifice, and this cross-sectional shape of the spray will remain constant at all distances 4from the nozzle, and even though the pressure of the fluid or gas varies.
ln the construction illustrated the orifice 5 has an oblongl shape with rounded ends, and the cross-sectional shape of the spray at all points thereof will have a similar shape as indicated in Fig. 5.
`Furthermore, this construction provides a spray which has a sharp welldefined periphery or edge, and there is an entire absence of scattering drops around the edge of the spray. Moreover, this construction will produce a spray which is of uniform 'consistency or density throughout its crosssectional area, so that if a liquid is being sprayed, the moisture at the center of the spray and at the outside edge will be of the same amount or degree.
The body l may be constructed in various ways without departing from the invention. lln the construction shown, the body is provided with a side opening 9 leading to the chamber 2 so that by screwing a pipe into said opening 9 a liquid or gas may be delivered to the chamber 2. The chamber 3 is also provided with an opening 10 to which a pipe may be connected, and through which gas or liquid may be delivered thereto.
The head 4 is shown as made separate from the body l and as being screw-threaded thereto at l1. The chamber 3 is shown as being formed from a short length of tubing or pipe which is screwed into the head 4 and extends axially through the body 1. This construction, however, is adopted as one convenient Way of making the head, and the construction of the latter may be varied in various ways without departing from the invention.
In using the spray nozzle, the liquid may be introduced into the chamber 2 and a gas under pressure into the chamber 3, or a liquid may be introduced into the chamber 3 and a gas into the chamber 2. In either case the spray which is produced will have the characteristics above described.
The spray nozzle can also be used for mixing two liquids by introducing the two liquids to be mixed into the chambers 2 and 3, respectively, under pressure.
. While I have illustrated a selected embodiment of my invention, I do not wish to 'be limited to theconstructional features shown. l
Having thus described my invention what l claim as new and desire to secure by Letters Patent is- 1. A spray nozzle having a body provided with two separate chambers, and a head provided with a delivery orifice and a plurality off-separate non-coaxial ducts or pasineaeee sages, all of which are so disposed that the axes thereof meet in the plane of the orilice, some of said passages connecting with one chamber and the remainder thereof connecting with the other chamber, whereby the non-coaxial streams issuing from said ducts meet in the lplane of the orifice, and at the point at which the are released from the nozzle, and there y become thoroughly mixed at the releasing point to form a spray having a definite shape.
2. rlhe method of spraying fluid through theo delivery orifice of a spray nozzle, which consists in projecting through said orifice a plurality of streams of fluid from different sources, said streams having different aries which are so disposed that they all meet at a common point in the lane of the orifice, and at the point at whlch they are released from the nozzle, whereby the streams are thoroughly mixedat said point of release and the shape of the spray is controlled.
3. The method of producing a spray by commingling a plurality of separate streams of fluid, Awhich method consists in bringing together at a common point a plurality of non-coaxial streams of fluid from different. sources, and releasing said commingling streams in the form of a spray of predetermined shape at such common point.
4. A spray nozzle having a body provided with two separate chambers and a head provided with a delivery orifice and a plurality of ducts or passages connecting said orifice with one chamber and another duct or passage connecting said orifice with the other chamber, said ducts or passages being noncoaxial and all of them being so disposed that the axes meet in the plane of the orice, whereby the non-coaxial streams issuing from said ducts meet .in the plane of the orifice and at the point at which they are released from the nozzle and thereby become thoroughly mixed at the releasing point to form a spray having a definite shape.
5. The method of spraying fluid through the delivery orifice of a spray nozzle, which consists in projecting throu h Vsaid orifice a plurality of streams ofuid from one source and another stream from another source, said streams having ,diderent axes which are so disposed that they all meet at a common point in the plane of the orifice and at the point at which they are released from the nozzle, whereby the streams are thoroughly mixed at said point of release and the shape of the spray is controlled.
ln testimony whereof, ll have signed my name vto this specification.
HERBERT Wrqnav.
