Description

June 8, 1954 .1. s. BISHOP DISCHARGE NOZZLE FOR LIQUIDS Filed June 28, 1951 FIG.3

INVENTOR. JAMES S. BISHOP BY DES JARDINS, ROBI SON & KEISER HIS ATTORNEYS Patented June 8, 1954 UNITED STATES PATENT OFFICE This invention relates to a discharge nozzle for liquids, and it pertains particularly to one whichhas circularly disposed discharge ports arranged radially beyond a non-perforated portion that spans the passage or bore of a conduit through which the liquids are supplied for discharge through the nozzle to said ports.

The invention is an improvement over the nozzle of my Patent No. 2,605,143 which issued July 29, 1952 from application Serial No. 750,799, filed May 2'7, 1947, and is incorporated by reference as a part of this case.

One of the objects of the invention is to provide a nozzle through which a plurality of small streams are discharged, and which is adjustable to control the conical spread of the streams.

Another object of the invention is to provide a nozzle through which a plurality of small streams are discharged, and having all of the streams discharged through perforations radially beyond the bore of the main supply conduit.

Another object of the invention is to provide a nozzle, having a detachable disc with a plurality of perforations therein, surrounding a non-perforated central portion, for discharging small streams of liquid.

Further objects, and objects relating to the details of construction in use, will definitely ap-' pear from the detailed description to follow. My invention is clearly defined and pointed out in the appended claims. A structure constituting a preferred embodiment is illustrated in the accompanying drawings forming a part of the speci fication in which:

Fig. 1 is a view of a nozzle embodying the invention, the majorlength of the nozzle being in longitudinal cross section and with the head on the outlet end slightly open.

Fig. 2 is a section through the length of a portion of the outlet end of the nozzle with the head fully opened.

Fig. 3 is a top plan View of the top of the nozzle head assembly.

In accordance with my invention, the nozzle is designed to deliver small individual streams of liquid and to have the lateral spread of the emitted streams varied by adjusting the nozzle. The delivered streams are emitted through a perforated disc in which small, separate holes or perforations are arranged radially beyond a nonperforated portion that is in alignment with the bore or passage of a collimating tube connected to a liquid supply means. By adjustment of the head assembly on the tube to bring the disc longitudinally toward and away from the end of the 8 Claims. (Cl. 299-132).

tube through which the liquid is supplied, the

angle of spread at which the streams are emitted from the disc is regulated. As the perforated-disc is moved nearer the end of the tube, the angle of the streams with the longitudinal axis of'thetube is greater, whereas the angle of the streams is less as the perforated disc is moved farther away from the end of the tube. The nozzle is adapted for any use where it is desirable toVary the angular spread of the streams of liquid-which are being discharged through the nozzle.

Referring specifically to the drawings in which like numerals designate like parts, numeral 2 is a collimating tube having a longitudinal bore-or passage 3 therethrough from the inlet end 4 to thedischarge end 5. The inlet end of the tubeis provided with any suitable means, such as external screw threads 6, for being attached to a conduit or other supply source through which liquid is adapted to be fed to the nozzle for discharge from the head. The tube is preferably cylindrical, and a portion i of its exterior wall may be polygonal for having a turning tool applied thereto for connecting the tube with a liquid supplyconduit.

The head 8 is adjustably attached to the outlet end of the tube by means of interfitting screwthreads 9 0n portions of the head and the tube. Screw threads it are provided on the exterior wall of the head in order to receive screw threads II that are on the inner wall of fiange [2 of a cap 13 which has a plane-or flat end portion, centrally open and closed by a disc 3a provided with a circular row of holes or perforations I4 extending therethrough, the perforations or holes being radially disposed beyond the bore or passage 3 of'. the tube, and in longitudinal alignment with the end face of the tube.- The head t is provided with an interior shoulder 55 against which seats a gasket ring it that is fitted within the head to be clamped against the shoulder by the cap bearing against the filler gasket ring ll that is interposed between the gasket and the disc. The gasket ring may be of any suitable material such as rubber, rubberized fiber or the like, which is compressible to make a snug fit against the exterior wall of the tube. The exterior wall of the tube is circumferentially grooved or slotted at l8 to provide spaced-apart opposite walls l9 and 20 between which the gasket may axially move in the adjustment of the nozzle head upon the tube. The. angular spread of the liquid emitted from the perforated cap disc isgre'atest (Fig. 1) when the disc is nearest to the end of the tube, but-not touching it and decreased (Fig. 2) as the disc is moved away from the end of the tube. The perforations ar disposed radially beyond the passage or bore of the tube with that portion 2| of the disc which is in longitudinal alignment with the passage or bore of the tube being non-perforated. The perforations are in alignment with the end face of the tube, and are spaced in from the inside wall of the filler ring so that there will also be a substantial non-perforated portion between the perforations and the filler ring. When the head is adjusted so that the disc is only slightly spaced from the end face of the tube and the liquid is supplied at moderate or strong pressure, the liquid is atomized and. discharged in a very fine spray, this result being effected with the head opened to about the distance shown in Fig. 1. When the head is opened wider from the slightly open position shown in Fig. 1, to the wide open position shown in Fig. 2, the liquid is emitted from the perforations in a plurality of separate streams with the angular spread of the streams being determined by the extent to which the head is opened. The cap 13 and disc 130! are preferably made in two parts with the part I3a being in the form of a thin disc of a diameter to fit snugly within the main part of the cap and beneath the central opening 23 therein. However, the cap and disc may be made as an integral unit or in a plurality of separate parts, as desired.

The nozzle device is satisfactory for use either with or without a valve member for opening and closing the liquid supply. However, there are instances where it is desirable to have a valve employed with the nozzle, and this may be a conventional type valve member, mounted between the passage 3 and the coupling member that is carried by the nozzle for connecting it to a hose.

From the foregoing description, the operation and use of the nozzle is obvious. The holes or perforations in the disc portion of the cap or the disc associated with the cap are disposed in a row, conforming to the annular end face of the tube at the outlet end so that they will be in alignment therewith. When the disc is moved toward or away from the end of the tube, the change in the distance between the holes or perforations I4 and the annular surface of the end of the tube changes the angular spread of the streams of liquid. The angular or conical spread of the streams is increased as the disc is moved toward the end of the tube to nearly closed position, and is decreased as the head is moved away from the end of the tube until, in fully opened position, the streams are nearly parallel with the bore of the tube when the disc is slightly concave as shown in Figs. 1 and 2.

I am aware that the nozzle device shown and described herein is susceptible of considerable variation without departing from the spirit of my invention and, therefore, I claim my invention broadly as indicated by the appended claims.

Having thus described my invention, what I claim as new and useful, and desire to secure by United States Letters Patent is:
