COOLING ORTCOYNDEINSING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 522,549, dated July 3, 1894.

Application filed April 1 7, l 8 9 3 To all whom it may concern:

Be it known that I, GEORGE A. BARNARD, of thecity, county, and State of NewYork, have invented-a certain new and useful Im-v provement intApparatus for Cooling or Condensing Fluids, of whichimprovement the following is a specification; v r l The object of my invention an apparatus for cooling or condensing fluids,- in which the cooling surfacesshall be so disposed as to thoroughly and effectively utilize the volume available within a determined ca-. pacity, and which shall be inexpensive in construction, and readily accessible for removal, cleaning, or repair. I

To this end,1ny invention generally stated, consists in the combination of an inclosing case of shell, fluid supply and discharge passages leading to and from said case, and a filling or 'body of piled or woven rods or wire, interposed between the supply and discharge pipesjalso, in the combination ofv an inclosing ease, fluid supply and discharge passages,

' an interposed piled or woven rod filling, and

tus illustrating an embodiment of ny invention Fig. 2,a similar section showingamodification thereof; Fig. 3, a partial vertical section on an enlarged scale showing the filling in piles or layers, and Figs. a and 5, transversesections, also on an enlarged scale, showing an interwoven or meshed filling.

In the practice of my invention,l provide an inclosing case or shell 1, which, as it is not subjected to any substantial degree of press.

ure, may be of any preferred material, as brick, sheet metal, or wood, and may be of circular, rectangular or irregular cross section as desired, and of such dimensions as are desirable under the conditions of service. The case 1 is set in an approximately verti cal position, in order to admit of the traverse and discharge of liquid through it by the acis to provide SerialNo. 470.683- (NomodeL) tion of gravity, and may be either wholly open at top, as shown in Fig. 1, or be provided with a cap having an opening or a series of fperforations, as preferred; The lower end of the case is closed by a bottom'plate 2, from which is led a discharge pipe 3, the outer open end of which is located in or above a lower delivery receptacle 4.

A supply pipe 5, the end of which is preferably provided with a perforated spreader or sprinkler 6, in order to distribute liquid in a series of fine streams or jets, is located above the case .1, its exit end and sprinkler preferably projecting into the case, in order to prevent thedispersion of liquid outside thereof.

The interior of the case, between the sup ply and discharge pipes, is substantially filled by a body or filling 7-,.of material so arranged as to present a series of closely sub-divided cooling surfaces, and small or narrow inter posed passages or interstices for the traverse of fluid from the supply to the discharge pipe. To this end,the filling7 is most desirably composed of small rods or wires, placed as closely together asfis compatible with the passage of fluid between them, and made preferably of metal, although other materials may be used if desired. The several members of thefilling may be arranged either in layers or piles, as shown inFig. 3, or be interwoven-into sheets or netting having a series of meshes, as i-nFigA, and, in the lat- "ter case, the interwoven sheetsor netting may be piled one above another, or they may be coiled or rolled, as indicated in Fig. 5. A single sheet maybe rolled spirally, or a series of sheets may be rolled one around another.

By the employment of closely adjoining rods or wires as a filling, as above described, avery large amount of cooling surface may be presented within a comparatively small compass, and wire being a good conductor, the coolingof liquid passing through the interstices or passages between the wires will be thoroughly and rapidly effected. It will also be seen that the filling may be readily removed and replaced when required for cleanupon a grated or skeleton frame support 8,

too

above the bottom plate of the case, but it may, if preferred, extend to or near the bottom plate.

In cases where the temperature of the fluid to be cooled is sufiiciently high to render the application of an external refrigerating medium necessary or desirable, a current of air may be forced through the filling, in order to exert a cooling action upon the currents of .3 fluid passing through the same. For this purpose, an air blast pipe 9, is led from a fan or pressure blower into the shell, the air blast either entering the same at its lower end and passing upwardly through the filling, as in Fig. 1, or being admitted at top and passing downwardly through the filling as in Fig. 2, as may be preferred.

In the operation of the apparatus, water supplied to the apparatus by the pipe 5, passes downwardly, by gravity, through the filling 7, and is cooled by contact therewith, and by the air blast entering by the blast pipe 9, when the latter is employed, the cooled water being collected in the lower receptacle 4.

The modification illustrated in Fig. 2 is designed for the condensation of steam without a vacuum, and the provision of purified water for boiler feed. The filling 7 is, in this case, inserted in two independent bodies, each resting upon a gratedor skeleton frame support 8, similar to that of Fig. 1. The air blast pipe 9 is led into the top of thercase 1, which, except as to said pipe, is closed by a conical cap 10, and an exhaust steam connection pipe 11, through which exhaust steam is delivered, is led into the space or chamber 12 between the upper and lower sections of the filling 7. Water is supplied tothe upper portion of the case by a supply pipe 5, having a perforated spreader or sprinklerG, said pipe being pref erablyled from the lower delivery receptacle 4, and being provided with a suitable lifting device 13, as a pump or injector. The initial supply of water to the receptacle 4, as: well as supply to compensate losses from evaporation or otherwise, is effectedby a pipe 11 14. An open topped pan or feed water re-jf ceptacle 15, is located in the chamber 12, in position to receive water passing outof the upper section of the filling 7, as well as to be 11 heated by the steam entering at the adjacent end of the exhaust connection 11. Heated l and purified water is drawn otf from thereceptacle 15, by a pipe 16. t

In operation, steam entering the case 2 through the connection 11, is condensed by 1; the .air blast from the pipe 9, and the cur-31 rents of water from the supply pipe 5. The;

condensed water passes downwardlythroughr Y the filling, and iscooled in its passage through l the same and returned to the supply pipe and spreader, the small percentage lost by evaporation and leakage being made up by supply through the pipe 14;. The receptacle 15 will be kept filled with purified water from the upper section of the filling, and such water, which will be raised to a high temperature by the heat of the exhaust steam, may be desirably used for boiler supply, for which or for other purposes, it is taken off through the pipe 16.

I claim as my invention and desire to secure by Letters Patent- 1.

In an apparatus for cooling or condensing fluids, the combination of an inclosing case or shell, fluid supply and discharge passages leading to and from said case, apiled or woven rod or wire filling interposed, in separate bodies, between the supply and discharge passages, an exhaust steam connection leading into the case between the bodies of filling, and a feed water receptacle located within the case adjacent to the exhaust steam connection, substantially as set forth.

3. In an apparatus for cooling or condensing fluids, the combination of an inclosing case or shell, fluid supply and discharge passages leading to and fromsaid case, a delivery receptacle below the case, a lifting device for elevating liquid from the delivery receptacle to the supply passage, a piled or-Woven wire or rod filling interposed, in separate bodies, between the supply and discharge passages, and an exhaust steam connection lead ing into the casebetween the bodiesof filling, substantially as set forth.

4. In an apparatus for cooling orcondensing fluid, the combination of an inclosing case or shell, fluid supply and discharge passages leading to and from said case, an interposed piled or woven rod or wire filling, an air blast pipe discharging into and through said filling, and an exhaust steam connection, substantially as set forth.
