SPECIFICATION forming part of Letters Patent No. 570,318, 'dated October 2*?, 1896.

Application iled November 9, 1895. Serial No. 568,475. (No model.)

.To all whom t may concern:

Be it known that I, WILLIAM J. LoUGH- RIDGE, a citizen of the United States, residing` at Lexington, in the county oi Fayette and State of Kentucky, haveinvented certain new and useful Improvements in Tater-Cooling Apparatus; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable Io others skilled in the art to which it appertains to make and use the same.'

My invention relates to improvements in water-cooling devices; and it consists of certain novel constructions, combinations, and

arrangements of parts, all of which will be hereinafter more particularly set forth and claimed.

In the accompanying drawings, forming part of this specification, Figure l represents 2o a side elevation of the devices embodying my invention, the internal construction being partly indicated by dotted lines. Fig. 2 represents a detail side elevation of the lower portion of my devices, the casing being partly broken away to expose the interior of the same. Fig. 3 represents, respectively, detail top plan view and side elevation, partly in section, of the water-supply pipe and flat spraying-nozzle for discharging water into the 3o casing. Figa represents a detail vertical section of the air-supply pipe and one of the nozzles for discharging air into the casing on the line A B, Fig. 2; and Fig. 5 represents a front elevation ofthe same. Fig. 6 represents a de- 3 5 tail vertical section through the top portion of the devices embodying my invention; and

Fig. 7 represents a perspective view of my improved devices,the side walls being broken away" to expose the interior and the spraying- 4o nozzles being omitted.

A in the drawings represents a casing which is preferably of rectangular form; l, a waterspraying coil; 19, an air-fan; q, an air-supply pipe dischargingunder said coil, and n, s, and

4 5 t a system of air-pipes for discharging air into the casing.

The casing A is provided at its top with an inverted-pyramid shaped cover m', which only partially covers the top of the casing, so

5o as to leave openings m2 for the escape of the air, as indicated by arrows in Fig. l. This cover is provided with a horizontal baffle-plate fm, which tends to direct the water thrown against it laterally into inclined troughs a, b, c, d, e, f, g, h, and t'. These troughs are supported against an interior screen-casing w, with which the casing A is provided. Each trough extends only the length of one side of the casing and discharges into the upper end of the next trough running at right angles thereto on the adjoining side of the casing, the construction being suchthat the water must fall some little distance from one trough to another and thus have the upward and inward currents of air pass through its finelydivided particles.

The coil Z is of spiral formation and is arranged in the lower part of the casin g A. It is supported by standards d and is provided with a pipe 7c, which is connected to any suitable water supply.

The spiral is provided with discharge-nozzles o. (See Fig. 3.) Each of these nozzles comprises a screw-threaded portion 0, screwed into the coil Z and locked in position by a nut 02, and a dat dovetail discharging end o3,adapted to throw the water upward in a finely-divided spray. The pipe q enters the bottom of casing A and extends up to the bottom of the coil Z, so as to discharge directly upward through the same. The casing A is provided with an opening u on each side and in the same horizontal plane with the coil Z. Each of these openings is partially covered by a shield or cover u, said shields giving the air drawn through said openings u an upward motion, as indicated by the arrows.

The lower trough discharges into a trough e, extending around the entire casing and having a perforated bottom through which the water passes in finely-divided particles and drops past the openings u into a tray a2, from which it is discharged by a pipe x. As the water falls past the openings u the air entering through the same passes through the Water and cools it.

The casing A is surrounded by a horizontal pipe t, which is connected with the pipe q by a branch pipe s. Vertical branch pipes n. n rise from said pipe t on each side of the casing. Each of these pipes is provided with dovetail spraying-nozzles o o, by means of which air is thrown into the casing A and against the screen w, as shown best in Figs.


4f and 5. The air is thus forced through the screen with the iinely-divided particles of Water clinging to it.

It will be observed vthat the prime object throughout my device is to first divide the water into ne particles and then force air through said finely-divided particles, which, of course, results in evaporation or the changing of a liquid into a gas. This change from a liquid to a gas requires heat, and this heat is taken from the remaining water, which results, of course, in lowering the temperature of the saine. Besides cooling the water by vaporizing part of it the water by coming in contact with the large volume of air of lower temperature than itself is also lowered in temperature by convection.

The current of air from the blower passes upward through the opening r with sufficient force to prevent any of the finely-divided spray entering said opening and iuterferin g with. the action of the fan or blower.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In a water-cooling device, the combination with an outer casing, of a water-spraying device located within the same, a blo-wer having an inlet into said casing below said spraying device and discharging vertically through the spray thrown therefrom, pipes in communication with the blower-pipe proper and with the outer casing, and air-passages in the sides of said casing for admitting air drawn into the casing by the forced current produced by the blower; said latter air passing laterally through the finely-divided water as it descends in said casing after being thrown up by said spraying device, subst-antially as described.

2. In a water-cooling apparatus, the coinbination with an outer casing, of an inner screen-casing, troughs arranged within the latter and adapted to discharge one into the other, a perforated trough into which the lower of said troughs discharges, a waterspraying device within said casing and a blower discharging into said casing, substantially as described.

3. In a Water-cooling apparatus, the combination with an outer casing, of an inner screen-casing, a water-spraying device in said casing, a blower, a pipe from said blower discharging below said spraying device, and a series of branch pipes connected to the blower and discharging into the outer casing and through the screen=casing at different points therein, substantially as described.

4. In a water-cooling apparatus, the combination with an outer casing, a baffle-plate located yat its upper end, a series of troughs discharging one into the other and arranged along the sides o f said casing, a spiral spraying-pipe in the lower part of said casing, flat discharge-nozzles in said pipe, and a blower discharging up through said spiral and the spray thrown therefrom, substantially as described.

In testimony whereof I hereunto affix my signature in presence of two witnesses.
