COOLING TOWER.

Application filed July 10, 1920. Serial No. 395,254.

To all whom it may concern- Be it known that I, EDWIN BURHORN, a citizen of the United States, residingat Hoboken, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Cooling Towers, of

"which the following is a specification, reference being had therein to the accompanying drawings.

This invention is a novel cooling tower, thatis to say, an apparatus of the class by which natural air currents are brought into contact with the water to be cooled, the lat ter being caused to pass by gravity throughthe-tower while subjected to the cooling influence. More especially the invention relates to the class of cooling tower in which 7 the descent of the warm water is interrupted and delayed by means of one or more structures or cooling decks arranged at various points in the height of the tower. for the purpose of preventing a too rapid passage of the water and failure to sufficiently cool the same.

The main object of the present invention is to simplify and improve the structure of cooling towers of the kind referred to, and to afford a mode of construction of greater cheapness and convenience, yet superior in its rigidity and durability. Other objects and advantages of the invention will appearin the hereinafter following description or will be apparent to those skilled in the art.

To the attainment of the above referred to objects and advantages, the present invention consists in the novel combination, arrangements, constructions, devices and other features shown or described herein.

In the accompanying drawings showing one form or embodiment of the invention, Figure 1 is a side elevation of a cooling tower embodying my invention, the same partlybroken away and certain parts omitted to more clearly show the structure.

Figure 2 is a perspective view showing the form and cross-section of one of the wooden troughs constituting a distributing element in thecooling decks.

Figure 3 shows in perspective a group of certain of the structural parts employed in assembling and securing the elements of the tower.

Figure 4: is a cross-section taken on the plane a-e of. Fig.5.

Figure 5 is a cross-section taken on the plane 5-5 of Fig. 4.

F1gure6 is a plan view of. one corner of the apparatus.

Figure 7 is a perspective View of one of the separating .orspacing elements. Above a suitable supporting base 9 are the tower uprights or corner posts 10 and these, at the top, are interconnected by the cross braces 11'. Along each of the four sides may be a series of louvers 12, although these are mostly omitted, and are wholly omitted from the far and near sides. The bottommost louver 13 is of extended width so as to discharge any water received thereon into the collecting pan 14. -The drain pipe'15 conductsthe'water from the collecting pan to the condenser or other apparatus. After the water has been again heated it may be returned to the apparatus by a pipe 16,

' which carries it toa distributing cross-pipe 17 at the t p, Supported by brackets 18, and having apertures 19 serving as orifices to discharge the water in the form of sprays upon or. into the distributing members or troughs of the topmost deck 21 below.

In addition to the topmost deck 21, there may be other decks 22, 23 or 24,,spaced suitably apart so that the descending water is caught and distributed by each deck and'de-' layed in its descent so as to insure maximum cooling by contact with natural air currents and by evaporation.

The several cooling decks may be of substantially identical construction, but preferably the distributing members or troughs in each deck are arranged crosswise or at right angles to those of the decks above or beneath.

Referring to'the structure of any one of the decks, it will be seen that it is supported by underlying'channels or beams 26 constituting part of the framework of the tower, and having upper flanges 27 upon which the deck members directly rest.

The wooden distributors or troughs 28 are shown as arranged horizontally in parallel relation in each deck, and slightly spaced apart. There may be any number of these, for example, nine in each deck. Each trough 's provided with overflow notches 29 so that the accumulating water in each troughwill pass outfrom the same at designated points in relation to the distributing members or" the deck beneath.

For example, each notch' may discharge directly into one of the troughs ofsthe deck beneath.

The parallel, spaced-apart troughs, resting on each pair of opposite channels, require to be permanently secured in such position, and l have devised the following very advantageous construction for this purpose. A separate bar or hold-down bar 30 is laid transversely on top. of each series of troughs. Preferably there are two hold-down bars at each deck, one near each end or" the series of parallel troughs, and, as shown, each bar may be engaged directly in the notches formed along the edges or the respective troughs. A hold-down bolt or hook 32 is preferably the. means of -forcibly depressing each bar 30, and-this is shown in the form of aneye bolt, the her being threaded through the eye of the bolt. i referably there is one such hold-down bolt or pin near each end of each bar, as shown, and the bolt may be located between two oi the troughs, thus giving a superior holding action and enabling the boltat the same time to serve as a separating means for maintaining the spaced relation of the two troughs.

For pulling down and securing the bolts 32 inplace, their lower ends 33 may be threaded and nuts 3e placed thereon. By this means the bolt may be suitably engaged with a portion of the frame-beam zti For example, an apertured plate or washer 35 may be located above the nut 34 and so as to bear upwardly against the flange 37 of the channel beam and the-under side of two of the trough members 28.

The above gives an extremely simple and inexpensive structure and one which, on the tightening of the several nuts 34, affords a high degree of security and permanence to' the structure.

The use of the hold-down bars 30, moreover, permits a' series of separators" 36 to.be provided on each rod, the same located between and so as to maintain the spaced relation of each two troughs in each deck.

" signature hereto.

aeaaera rators arev threaded upon each hold -down rod 30, which is then inserted in place, as

shown, and the washers and nuts applied at the lower ends of the bolts, and tightened up ,after theseveral elements are adjustedinto proper relation.

it will thus be seen that I have described a cooling tower embodying the principles and attaining the advantages of the present, invention. Since many matters of construction, combination, arrangement and other features may be variously modified without departing from the underlying principles, it is not intended to limit the inventlon to such features except so far as set forth in the appended claims.

ll hat is claimed is:

1. in a cooling tower, a cooling deck oomprising a series of spaced apart horizontalparallel troughs, those in one deck arranged crosswise with respect to the deck above or below, the troughs in each deckbeing supported upon frame beams'at their ends and held down by overlying bars at their ends, hold-down bolts engaging each bar near each end and extending down between two troughs to a point of attachment to a frame beam and separating elements engaging each bar and located between each two troughs.

In testimony whereof, l have afiixed my EDWIN BURHORN.
