FLUID-CONDITIONINe APrARATUs.

-ElPa'so, in the county of El Paso and State of Texas, have invented certain new and useful Improvements in Fluid-,Conditioning which the following is a specification. Y

The object of this invention is to pro-` vide new and improved means for mois-tening and cooling air, also to provide for the collection and accumulation of the cooling liquid, generally water, that it may be held stored for any use for which it .is applicable. In its broader aspects the invention is capaas to effect the requisite cooling of water in radiators' of automobiles orfor the immedi ate cooling of liquids circulating .in the' water jackets of internal combustion engines, or'for the cooling of rapid lire guns,

or it maybeapplied for the purposes ofrefrifferation in refrigeratingplants, or for coozling in Ventilating systems.

In the accompanying specification the olis-v closure is of a preferred embodimentapplied to a Ventilating fan of theordinary electric `motor driven type, the fan shown being of the oscillating type.

In vthe drawings accompanying and forming part of this disclosure :Figure 1 is a side elevation ofthe electric fan with myv I device applied thereto. Fig. 2 is a viewl on .line 2-2 of Fig. 1 in the direction indicated by the arrow. Fig. 3, is an enlarged detail lView'of parts in section. Fig; 4 is a the outer ring and collecting shell. Fig: 6

is a view showing the application of the device to al fan adjustable in a. vertical plane. As the details of the fan and motor may Abe of any of the well known types a par-A ticular description of the same is deemed llIlIleCeSStIy.

As shown the motor proper is indicated at 1, the same being mounted o n any proper vbase 2K, the motor shaft 3, carrying a fan 4 oi'any desirednumber. of radial blades projecting from a central boss secured on the Imotor shaft. The fan as is usual is proteoted by a wire guard 5 rigidly securedf'to the motor casing and lof alsize to extend around andgin front of the fan. As stated Specification of Letters Patent.

all these'parts may be of the usual construction exceptfwhen, as hereinafter-described, such changes are made as are necessary to permit of the application of the following construction forming the preferred embodiment of my invention, .which comprisesr--a ring 11 which may be of metalvulcanite or any other suitable material and which is in` wardly on each side of the central groove and the outer edgesare bent sharply inward as flanges 13. Inclosed, within the outer ring 11 and supported therefrom by radial strips- V14 are a series of spaced rin s 15, 15a, 15"` and 1.5". These ringsy are of any suitable material, as metal, rubber or the like, and

are of a width e ual tof that of the outer4 ring and like suc outer ring have their edges bent sharply inward to form like flanges. Each inner ring is of substantially the same diameter for its entire Width eX- ceptfor the series of grooves 16 formed in the ring and extending for the width of the ring, so that incross section the rings appear corrugated as shownin Fig. 3. Each ringA also at thebottoin of each groove is perforated by a series .of openings 17K of relatively small diameter. Care must be exercised that the series of inner rings are` rigidly supported within the outer ring and for Asuch purpose additional securing strips similar to 14 may extend from both sides or edges of the outer ring, the strips being 'securely fastened to the several flanges at the edges of the rings. Also the outer ring tached tothe fan'blades sc that the whole kseries of rings may vmove as one with the fan blades in their. rapid rotation.

water or liquid reservoir 18 is shaped to conform to the motor casing and to be supmust be securelycarr'ied by the brackets at- I ported thereon with the bottom of the reser- A pipe or tube `Iwitlacock'20 therein tor control the flow of .'water orother liquid "'ivoireveryslightly above the motor shaft.

dition of a tine frost or snow,

leads from the bottom of the reservoir and extends .above the motor shaft, this pipe is closed at its outer end but on its under side is perforated by a row ot' small openings 21 which extend along the pipe Jfor approximately its length within the width of the innermost-ring. i

With the construction as thus arranged water o r other liquid/is delivered from the pipe upon the motor shaft -or .within the periphery of the inner ring, and such water .or other liquid by the -centrifugal force produced by the rapid revolution of the Jfan is caused to spread within the innermost ring and to be forced as a fine spray through the perforations of'fthe ring. Such spray' is in turn collected on the inner tace ot' the nextIl outer ring and again forced as a line spray through the perforations of the ring, and

the consequent absorption of heat thusproducing a cooling of the air and the mist and also of the several rings, and as the liquid spray is cooled progressively as it passes through the series of rings from the inner ring to the outermostva final cooling is secured of the spray as it is collected within the outer ring which may if desired bring such mist or spray very nearly tothe con- 'll am aware that it is not new to project a fine spray of water or liquid into an air current, also that devices have been construoted which employ the centrifugal force of 'rotating parts vto throw the liquid spray in to `the air, but l believe that it is broadly new to provide means for collectingl the spray after it has been subjected to the cooling produced by -the evaporation of some part'of it in an air current, andto successively repeat the operation to secure a progressive cooling of the liquid, also to make use of such cooled spray to reduce the tem@ perature of air.

lt the device as described is operated at that speed and under such conditions as to produce a line snow or frost within the confines of the outermost ring, it is only neces sary to operate the same until the snow or rost'tills the outermost ring and then to remove such snow from the ring by means of a spoon or proper scraper, but as the device will more often be employed simply lfor .cooling and moistening the air current suprefr/aser plied by the fan and also torthe cooling ot a water supply, the construction is preferably provided with means for collecting and receiving the cooled liquid as it accumulates in the outer ring. `For such purpose the outer ring is formed with the central channel or groove l2 in' which the cooledliquid accumulates as it is condensed from the fine mist thrown through the pertorations in the outermost of the perforated riiigslc. To provide forv the discharge o'f theliquid from the channel l2 in the outer ring, the bottom of such channel isperforated by a row ot small openings at desired places in the ring two of such rows ot perforations being shown. rk valve comprising a plate 22 preferably with a facing oi' cork or leather 22a is secured on a small shaft 128 mounted in the sides of channel l2, this shaft extends at one end beyond the side ot the ring and is bent inward vto formtlie arm 23 which carries "at its end afbeaiing roller Q4, a spring 25 is coi-led around the shaft Q3 ciigagingat one end with the ring and at its other end with the arm 23 so as to hold the plate Q2 down to close the pertorations in the ring. A cam plate 26 is secured on the wire guard Ain position to be engaged by the roller 24, as the ring isl revolved to throw the arm outward to effect the elevation ot the plate 22 at which time the liquid in the channel is discharged through the pert'oratiens into a receptacle placed to receive the same. Such receptacle 27 is of any suitable material as metal, rubber or. the like and comprises an inclined lrear wall 27a and curved sides 27h the sides curving inwardly toward lthe wall, the whole in cross section appearing shaped as the numeral 6, the receptacle being` placed so that liquid discharged from the ring is driven in between the curved sides striking against the rear wall and trickling downward to the ends of the receptacle. Pipes 2S lead oil1 from the ends ot the receptacle and conductthe liquid back into the reservoir 1,8 mounted on the motor casing thus a supply ot cool water or other liquid is maintained in the reservoir, the liquid if water kept sufficiently cold so as to obviate all necessity ior ice it used for drinkingpurposes. i

liVhile so shown, however, it is obviously not essential that the bottom of the reservoir should be above the motor shaft but'it may extend below and the water may be delivered from the pipel9 on the interior of' the inner ring l5 below the motor shaft.

A modification of the collecting` receptacle and outer ring is shown in Fig. 5, in which the channel l2 ot the ring` is perforated throughout its extent and no valve controls ,the pertorations7 the liquid as thrown from the ringbeing received into aii annular reoeptacle 27 of the same shape in cross sec tion asthe receptacle 27, but completely encircling the ring, the collected moisture lOG modification may be preferablyjemployed' plane, or if mounted v shown inFig. 6.'

The .air and liquid. conditioning device may be applied to a fan mounted'on a'shaft rotated by'any means`in place .of the motor draining down to4 the. lowermost point of :the

receptacle 'and being carried offby awppej 28 to any desired reservoir or place.` lSuch if the fan is placed to rotate in a horizontal s0 as to be adjustable as illustrated, such as a belt, gearing, etc.A v

The number of rings may be Va-riedf'innumber and Width to Vary the amount of .mist or, spray through which air .is forced,"

or a ring or rings may be made Wider than the other rings, or the 4series may bel con! structed of rings of increasing ordecreasing width respectively from the jcenterout-' wardly. A Variation mayialso be' made in the .Width and depth ofthe corrugations the different rings, and likewise the size of theperfor'ations in, the rings may be Varied,

` Aplurality of series of rings. may also' be provided vWith a 'single fan lor With a, pluralityof fans. y

The' deyice may Y intake passage When built on a larger scale for cooling theaters andlother buildings.
