.TAiviEs KELLY, or PROVIDENCE, RHODE IsLAND.

To all whom 'it may concern: y, Be it known that I, JAMES KELLY, a citizen of the United States, residingat Providence, in the county of Providence and State of Rhode Island, have inventedA certain new and useful Improvements in I-Iumidiers, of which the following is a specification, reference being had therein to the accompanying drawings.

Like reference letters indicate like parts. Figure l is a view in elevation of my improved discharging nozzle for humidil'iers. Fig. 2 is a central longitudinal view ofthe same. Fig. 8 is a view partly in top plan and partly in cross section-on line .fw w of Fig. 2; Fig. 4 is a view in cross section as seen on line m of Fig. 2. partly in top plan and partly in cross section on line y y of Fig. 2. partly in plan and partly on line .a c of Fig. 2. Fig. 7 vation of a modified form of my invention. Fig. 8 is an inverted or bottom plan view of the lower end of the nozzle shown in'Fig.' 7,

My invention relates to the class of humidiiiers and more particularly to the .discharging nozzles therefor; and it consists of the novel construction and combination of the several parts hereinafter described as specifically set forth in the claims.

The humidiiiers to which my invention especially is applicable are those used for purifying, cooling and moistening the atv mosphere in mills for the manufacture of yarns and textile fabrics. In such factories the air is liable to become very dry and to be more or less filled with floating particles and fibers, which are harmful to the health of the operators.

The improvement hereinafter described in cross section 1s a view 1n elehas for its purposes the simplification of the discharging portion of a humidifying apparatus, and the division within the nozzle, of the one entering current ,of mingled water and air under pressure into several currents, in contiguity, one with the others, by means of a plurality of parallel passages or tubes, which conduct the several currents to a common annular discharging device; and also an increase in the proportionate area ofinv` ternal tube surface, against which thesaid water and air impingeduring their passage, resulting inthe greater degree of mixture of the two elements.

elusive; A-t the upper end the nozzle has an n exterior screw thread Z9 and at thelower end it has `anlexteriorscrew thread c. -A ltubular oouplingB'has an enlarged tubular end C, concentric therewith, and is provided there with, ank interior screwthread, engageablev with the screw thread 'b of the nozzle A; and it has at its upper end an interior screw` thread QZ, yby which it is engageable with a suitable pipe, which conducts to said nozzley mingled water and air under pressure', as is well known in kdevices of this class. the yenlargement C of the coupling B, `on accountof the greater diameter of theformer, there is a chamber c. At the center of the upper 'endof the nozzle A there is a conicallyshaped, upwardly-directed deflector D, whichextendsfup into the chamber c. The deiiector I) is thus located between the upper ends .of the several tubular passages a, as seen in Figs. 2 and 3. A cap E, having is engageable thereby with thescrew thread c at the lower end of the nozzle A, considerably below, however, the discharging orifices thereof, presentlyy described.l Thelower end of each tubular vpassage a is closed by a plugrF, .or other suitable means, accessible by the removal ofthe cap E.

two of the tubular passages a are shown in full lines and one of thewother tubular passages a is shown in dotted vertical lines.. Y L

An annular discharging iiange G sur Within x rounds the nozzle A ashort distancejabove the cap E, and is dished, or concaved, on

its upper surface, as shown in Fig. 2. Each tubularl passage a has a small slot or discharging orifice H, extending through to the outside ofthe nozzle AL and located so as to discharge the contents of the tubular passage a upon the upper dished surface of the iflange G. Y

The operation of my improved nozzle for humidifiersis as follows. Mingled air and water, under pressure, as usual in humidifying devices, are discharged through a feed pipe (not shown), which pipe enters the open end of the coupling pipe B, and engages therewith by the screw threads d. The volume of mingled air and water passes through the upper tubular part of the coupling B into the chamber c, and is divided therein by the conical deflector D, and directed into the tubular passages a, and thence is discharged through the several orifices H. The currents, so discharged through the orifices H, impinge against the upwardly inclined surfaces of the annular fiange Gr, and are thus projected radially outward at a sufficient angle to penetrate a considerable distance into the external atmosphere, which readily takes up and absorbs the moisture so provided.

Each of the tubes a is closed at the bottom by a plug F, inserted or engaged therein in any suitable manner. The current in the lower portion of the tube a is thus turned back against itself, which results in a still more thorough division of the water and the mixing thereof with the air to an increased degree of fineness. The discharge, therefore, through the orifices H is very forcible, as there is no exit for the air and water current from the tube a, except through the discharging orifices H, and as these openings are constricted and of limited capacity, there is an accumulation of power within the tube a, and a nozzle effect is given by the constricted passage H, so that the jet of mingled air and water issuing therefrom penetrates far into the external atmosphere. There is practically no sediment carried into the tubes a, but if there should be any it is forced to the bottom of said tubes. Any formation of sediment is removable therefrom by unscrewing the cap E, and withdrawing the plugs F.

In Figs. 7 and 8 is shown a modified form of the apparatus. In Fig. 7 B is the coupling and C the enlargement to form the internal .space or chamber. Four (or any other desired number of) pipes, designated as a', a, are grouped or clustered symmetrically around a central rod M, which is longitudinally grooved, as illustrated in Fig. 8. These grooves are concaved and of a curvature to adapt them to serve as seats to receive and support the tubesa, respectively. These tubes a may be secured to each other by solder, indicated at m, or otherwise, and may also be soldered or secured to the central rod M. N, N, are plugs to close the lower ends of the tubes a', a. Each tube a has a discharging orifice (not shown which opens into the concaved portion o an annular flange Gr. The deflector is indicated in Fig. 7, by dotted lines and is designated as D. The operation of the device illustrated in Figs. 7 and 8 is the same as that of the device shown in Figs. l to G, inclusive.

It is evident that the device need not be constructed of several (originally) separate pipes or tubes, soldered or secured together as specified, but may be cast in one piece of metal, having the longitudinal exterior corrugations illustrated in Fig. 7 and provided with tubular passages, which are either formed while in the mold, or subsequently bored out.

The purpose of having a plurality of tubes or passages a (or a) is to increase the proportionate interior tubular surface in relation to the volume of the contents of each tube or passage, so that said contents have a relatively increased impinging contact with the tube or passage, by means of which the passing current is more frequently diverted and with more comparative force, and so more broken up, thus insuring a very thorough mixture of the air and water. rl`hc finer this mixture, the more readily it is absorbed by the external atmosphere, and the greater the quantity of water which said atmosphere can take up and assimilate; and besides this, the discharge is more uniform in quantity, and the distribution of it in the different radial directions is more equal th au if there were one single column of mingled air and water in a single tube, discharged through a single nozzle, or even through a plurality of radially directed orifices. The comminution of the water element of the volume in the tubes a (or a) should be so fine and the mixture so nearly perfect that the water discharged is in a sufficiently fine spray so as not to be liable to condense and consequently to drip. I have demonstrated that by my improved humidifying device hereinbefore described, three gallons of water per hour can be discharged and dissipated into the natural atmosphere without. any drip.

It is seen that the discharging orifices H are not adjustable, but are of invariable capacity. It has been found by experience that by attempting to vary the dimensions of such discharge openings, a considerable degree of skill and care is necessary in order to prevent drippage. In my device, the size of the discharging orifices is determined carefully by experiment, and when so fixed, is incapable of variation, thus obviating all danger of drippage, or the exercise of any special care or skill, the results having been exactly predetermined and the discharge rendered positive, uniform and reliable.

I claim as a novel and useful invention and desire to secure by Letters Patent 1. In a humidifier for discharging mingled water and air under pressure, the combination of a nozzle having a plurality of tubular passages extending longitudinally through said nozzle and parallel with each other, each of which passages has a closed bottom and is provided with a radially vdirected discharging orifice; a deflecting device mounted in the upper end of said nozzle centrally between said tubular passages; and an annular fiange mounted on the nozzle at or adjacent to all said discharging orifices and approximately in the plane thereof, and provided with a concaved upper surface; all arranged so that the current of said mingled water and air is divided and separated by the defiecting device and directed thereby through the tubular passages in separate currents, which are discharged therefrom upon the concaved surface of the annular flange.

2. In a humidifier, the combination of a plurality of parallel tubular passages constituting a nozzle, and each having intermediate its ends a discharging orifice directed radially outward; a detachable plug closing the bottom of each of the tubular passages;l an annular flange mounted on the nozzle at right angles thereto and having a concaved upper surface adapted to receive the discharge from all the tubular passages and to spread and direct the currents discharged from said passages; a conical defiector located at the upper end of said passages and centrally between the same; and a tube hav ing a chamber wherein said passages open at the upper end thereof and wherein said defiector is located, which tube is adapted to conduct into said chamber mingled water and air under pressure.

3. In a humidifier, the combination of a nozzle, having its upper and lower ends threaded and provided with a plurality 0f parallel tubular passages; a supply pipe in l threaded engagement with the upper end of the nozzle and having a concentric chamber at its inner end, which vpipe is adapted t0 conduct to said chamber and nozzle mingled water and air under pressure; a discharging device in each of said tubular passages intermediate its ends, all said discharging devices being in one plane which is at right angles to said tubular passages, respectively; a detachable plug closing the lower end of each of the tubularpassages; a cap engaged with the lower screw threads of the nozzle; a spreader upon the nozzle in said plane adapted to receive the discharge from all said passages and to direct radially and disseminate in the external atmosphere the said discharge; land a conical deflector located in said chamber upon the'upper end of the nozzle and centrally between the upper ends of the tubular passages, arranged and adapted to divide the mingled water and air currents lin the chamber and direct the divided currents equally into said tubular passages.

t. In ahumidifier, the combination of a cast metal nozzle having a plurality of longitudinal bores and discharging orices for said bores, respectively; a supply pipe adapted to convey to said nozzle mingled water land air under pressure; and a fiange upon the exterior surface of the nozzle and so located and adapted as to receive and deflect said mingled water and air under pressure when discharged thereon from said chamber.
