To all whom it may concern .1

' Be it known that I, Janos GIBnoNs, a icitizen of the United States, residing at E WeSt Park, in the county of Cuyahoga and "State of Ohio, have invented certain new and useful Improvements in Spraying-N07,

.- a Widespread, cone-shaped, hollow mass of zles, of, which the following is a specification, reference being hadtherein to the accompanying drawing This invention relates broadly to improven'ients in spraying devices and, specifically, to spray nozzles peculiarly adapted for spraying trees and the like. v

One of the primary objects of thewmvention is to provide a spray nozzle of such construction. that the spraying-fluid ma v be discharged therefrom either in'the form of relatively short carrying powerand of'larg'e "diametra'l area, or in the form of a solid body of relatively greater carrying, power and of relatively smaller diamotral' dimen- "I sionsh Anotherobject is to provide, insuch a construction, means for minutely controlling the flow therethrough of the spraying-final whereby the character of the spray dis-- charged therefronrmay be accurately varied. Anotherobject is to prov'ide'a structure in which the spraying-fluid maybe pro -jected through apertures in a plurality "of i flow-capacity to'change the character of the spray as it isdis'eharged fromithc nozzle.

.:from sliding-movement thereof, the slidspaced-apart members, the a-perture'in one of the members .lofilng of relatively different cross-sectional area from the cross-sectional areas'of the apertures in a second member but whose aggregate areas equal the area of the aperture in the first member, where-.

.by' the: flow through the apertures is bal anced; means being provided tor. controlling the flow therethrough for varying its This invention seeks in geueralto provide for definitely controlling a relatively rotative movement of the parts as distinguished ing actionof which is uncertain; so that,

. from an operative standpoint, my device, as

has beenfound in practical use, possesses a high degree'of eiiic ency and durabilityand 'Y'which, structurally considered, is of. great sis simplicity; I I I p r Certain other objects will'be obvious from theanneaed drawings, While otherswill be pointed'out in the following description.

That the invention may be clearly comprchended, drawings illustrating one of the many possible utilizations of the same are hereto annexed, asa part of this disclosure;

it being manifestthat other possible utilizations' and embodiments (employing theun derlying within the spirit thereof and Within the objects contemplated thereby.

principles of my invention) fall In these drawings: Figure 1 is a view in.

Referring. to these drawings, the reference character 1 designates nozzle-body,

preferably of the form shown, and hollow to provide a fluid-containing chamber- 2] This communicates, by an el'ongmted-chanml 3, with a port 4 into-which is threaded a pipe 5 that connects with a suitable source (not shown) of spraying-fluid. The portion of the n'ozzleopposite to' the port 4 is enlarged, and thereon a cap devicc 6 is mounted. In the particular embodiment disclosed, this includes a cap-piece 7 p1"efcr'- ably v threaded onto the nozzle-body, as shown, and provided with an enlarged opening of approximately the same diametral' dimensions as that of the-chamber 2, The

wall of-the' outer end ofthe nozzle-body is .cut to form an annular seat 9 for a spraycont'rolling and balancing diskme1nber 10. Seated upon theouterend of the nozzlebody and preferably overlapping the outer i the aperture 13 in the disk edge of the disk-member 10 is a spacingmember 11 which, preferably and as shown, is of resilient material and of somewhat less internal diametral dimension than that of the opening 8 in the cap-member 7.

Retained by the cap-member 7 is a disk 12 provided with a. central aperture 13 which is, preferably and as shown, formed with outwardly-flared w'lls, for a purpose presently to be explained. The member 11 maintains the disk 12 and the disk-member 10 in spaced relation to provide an eddychamber 1 1 with which said aperture 13 communicates.

The disk-member 10 is, preferably and as shown, provided with two series of flow passages; one comprising a primary-aperturc 15 disposed in approximate alincment with 12 but of larger diametral dimensions than that aperture. as shown; the other series comprising a pluralityin this instance, there are three-secondary apertures 16. 17 and 18. Preferably and as shown, the wall of the aperture 15 is straight, while those of the secomlary- apcrtures 16, 17 and 18 are cut at an angle to the aperture 15, and these sccondary-apertures are concentrically arranged in relation to the primarv-anerture 15 in the disk-member 10 and also with the aperture 13 in the disk 12. i

It is a feature of my invention, and an important one, that the diametral or crosssectional areas of the primary-aperture 15 shall be apl'n-oximately three times that of each of the sccondary-apertures; or, other wise stated, that the aggregate of the (lian'letral dimensions of the secondary-apertures shall be equal to that of the primaryaperture 15, as shown in Fig. By reason of this feature, the flow series of apertures is, under certain conditions, balanced; that is to say, the flow through the primary-aperture 15 is equal to the aggregatesfiow through the three secondary-ape1.'tures. From this, it will be evident that, by varying the normal flow-capacity of the primary-afperture 15, the equalized flow, or equally-balanced capacity, is in consequence changed. To the end that this variation may be conveniently and accurately accomplished, and to a minute degree, and then maintained, I provide means adapted to control the flow of the fluid through the primary-aperture 15. These means, in my preferred embodiment, include a controlling-member designated, generally, by the reference-character 19 and which, in this instance, is provided with an enlarged head 20 on its inner end; with a knurled piece 21 on its outer end; and with a stem 22 which is movahly guided in an opening 23 that opens into the fluid-containing chamber 2. The opening. 23 al 0 communicates with an enlarged recess 24 adaptthrough the two solution is discharged from ed to receive packing in its lower por tion. Threaded into the recess is a stufiingnut 26 provided with a bore 27 which. is threaded to receive a threaded portion 28 of the stem 22. By reason of the fact that the controlling-niember 19 is threaded into thestufling-nut 26, it has a compound r0 tative and longitudinal movement by which it is accurately positioned in relation to the primary-aperture 15; and, by reason of the fact that the head 20 thereof is of larger diametral dimension than that of the prilnary-apcrture, it is adapted to be seated over and close said primary-apcrture when it occupies its innermost position, as shown in full lines in Fig. 3. When the primaryaperture is closed, the flow of fluid is entirely through the angularly-cut apertures .16, 17 and 18, and, by reason of their position and character, they, in conjunction with the walls of the spacing-member 11, produce a whirling or swirling motion of the fluid, which, by reason of the resultant pressure. is caused to discharge through the apcrture 13 in the disk 12. The angle of exit of the fluid, then, will be approximately along the oblique lines AA, with a diameter equal to the laterally-extending line A. In other words, when the controlling-member 19 closes the primary aperture 15 in the plate 10. the'tlow of the solution is through the sccondarv-apcrtures 16, 17 and 18' therein and. thence, into the eddy-chamber 14., The eddy-chamber is then caused to rotate or whirl by reason of its angle of entrance into the chamber.v The liquid, then in the chamber 11. is discharged through the aperture 13 in the plate 12 in the form of a hollow cone of a maximum angle represented by the atorementioned lines 1\-A radiating from the aperture 13. As shown, this position of the controlling-device with reference to the aperture 1.5 permits the most widespread discharge of the spray of which the nozzle is capable. lVhen, llOWQX'Ql, the controllingdevice 19 is positioned somewhat back and away from the aperture, as indicated in dotted lines in Fig. 3, a portion of the solution is permitted to pass through the aperture 15 as well as through the angularly-cut secondary- apertures 16, 17 and 18. The passage, then, of the solution through the primary-aperture 15 has the effect, first, of reducing the maximum angle of the spray through the aperture 13, which angle is inclicated by the lines B-B, also radiating from the aperture 13; secondly, of filling up the center of the cone, so to speak, so that the the aperture 13 as a solid body, the diametral dimension of which is indicated by the line B; and, thirdly, of projecting the spray to a greater distance. Thereby, perfect control of the delivery of the spray and a consequent savliquid which is discharged into this ing thereof is accomplished. Again, when the controlling-device 19 is movedvbaclt to its rearmost position, as il'idicat'ed in dotted lines in Fig. 3, and is, thus, still farther-removed from the aperture 15, alarger quantity of the solution is permitted to pass through the primary-aperture into the eddy-chamber 14. This causes, first, a still further reduction of the angle of the spray, as indicated by the lines C C, and, secondly, a still further projection of the solid cone of spray, having a diametral dimension indicated by the line C, which effects a still greater definition in the control of the spray, with a consequent greater saving of solution' than that where the controlling-device occupies its intermediate position of adjustment. It will, therefore, be obvious that the positioning of the controlling-device 19 L. in relation to the primary-aperture l5 enables the operator to effect a discharge of the spray through the aperture 13 at any fixed angle between-the maximum angle, indiicatedby the lines AA, and at any reduced angle, as indicated by the lines B-B,

and (I O.

The flared form of the wall ofthe aperture 13 of the plate 12 is prii'i'iarily designed to increase the distance between the face of the plate ofrthe disk 10 and the aperture 13 in order that the rotating or whirlingmotion which is given to the solution that enters the eddy-chamber 14 through the an gularlycuit apertures 16, 17 and 18 may be imparted to the solution which passes into the chamberll through the prin'iary-aperture 15.,

From the foregoing, it will be perceived that l: have succeeded in devising a spray-- nozzle which is well adapted to achieve the several objects and ends 111 View.
