Specification of Letters Patent. I Patented 69$, 1'? 1916.

Application filed September 1, 1915. Serial No. 48,457.

To all whom it may concern:

Be it known that I, MERTIE THmns, a citizen of the United States of America, residing at Wichita, in the county of Sedgwick and State of Kansas, have invented certain new and useful Improvements in Air-Cooling Devices, of which the following is a specification.

My invention relates to means for artifi cially cooling air, and the objects contemplated thereby are the provision of a device in which material having the characteristics of absortion and capillary attraction is em ployed as a medium for carrying a cooling liquid in such manner that air at a high tem perature, upon impinging thereagainst will be cooled and slightly humidified; to pro vide a device of this character'which is extremely simple in construction and arrangement, and which accordingly may be manufactured at a minimum cost; to provide a device which makes it necessary for the circulating air to traverse or take a tortuous course, thereby subjecting the air to the maximum cooling surface; and to provide a device which is thoroughly braced and re inforced at all points so as to effectively resist strong currents or blasts of air.

To the accomplishment of the recited objects and others coordinate therewith, the preferred embodiment of my invention resides in that construction and arrangement of parts hereinafter described, illustrated in the accompanyingdrawings, and embraced within the scope of the appended claims.

In the drawings :Figure 1 is a vertical sectional elevation showing my device as adapted to the frame of a window. Fig. 2 is a perspective view partly broken away, of the device removed; and Fig. 3 is a transverse section of the air cooler as shown in Fig. 2.

Referring more particularly to the drawings for a detailed description of my invention the numeral 1 designates a frame comprised of vertical side members 2-. an upper reservoir 3 and a lower receiving chamber 41. The reservoir 3 is provided with a supply pipe 5 equipped with a suitable valve 6, and also carries a cover or closure, as 7. Arranged in staggered relation along the bottom of the reservoir 3 are a series of small pin openings 8, and eXteriorly of the bottom in alinement with these openings are a plurality of depending bails 9 which serve to support the vertical absorbent tapes or strips 10. These tapes are doubled upon themselves or. fashioned into endless bands, the vertlcal parallel portions of which are rela tively close together, and at their lower ends they are threaded through the slots 11 in the upper portion of the receiving chamber 4:, the slots being made sufliciently large so that their walls will not contact with the said tapes. In order to effectively brace these strips and render them secure against flapping I provide a series of transverse noncorrodible wires or elements 12 which are stitched with respect to the strips, as at 13, and sustained at opposite ends by the vertical side members 2 of the main frame portion.

By the way of a single illustration, I have shown my invention fitted 'to a' window frame 14:, as exhibited in Fig. 1, although'it will be understood that the principle of the device is applicable to various other uses. In this case I may provide an outlet 15 leading from the receiving chamber 4 and designed to supply a similar reservoir as 16 located in the window frame 17, which is just below the uppermost window frame 14:, thereby carrying out the idea of continuity of arrangement which obviously would permit of equipping all the windows of large otlice buildings, hospitals, etc. with facility.

In operation, the valve 6 connected to the main supply pipe 5 is opened thereby permitting a suitable quantity of cool water to enter the reservoir 3. This water trickles through the small pin openings 8 in the bottom of the reservoir and is precipitated upon the upper ends of the several endless bands of tape 10, each series of openings serving to feed the two portions of each strip. The

'moistening of these bands is manifestly accelerated by reason of the principle of capillary attraction coupled with gravity, and it follows that in a veryshort time the entire length of the several tapes will be thoroughly saturated with water. Upon the air, which is presumably of a higher temperature than the water, impinging against the surfaces of the moist tapes and being obliged to traverse 'a' well defined zig-zag course, it will readily be seen that the temperature of the air when issuing through the opposite side of my device will be lowered. While-it is true that the natural course of the air is interrupted owing to the angular disposition of the tapes, it is likewise true that the air is not subjected to any filtering process,

which later would be likely to cause a clog ging of the interstices of the tapes. By reason of the relatively close disposition of the parallel portions of the individual tapes, the air entering therebetween will be caused to intimately contact with the moisture and is thereby cooled and slightly humidified. The spaces between the individual endless bands of tape are greater than the spaces between the parallel portions thereof so that too much moisture will not be taken up by the air as it passes therethrough.

It should be understood that in its broader aspect the invention comprehends the em,- ployment not only of the various means described, but of equivalent means for performing the recited functions.

While the arrangement shown is thought at the present time to be preferable, it is desired to reserve the right to effect such modifications and variations thereof as may come fairly within the scope of the appended claims.

1. In a device for cooling air, the combination of a reservoir having a series of outlets, a receiving chamber, and two rows of bands of absorbent tape having their upper ends disposed beneath said outlets and adapted to catch the drippings therefrom,

while the lower ends of said bands terminate within said receiving chamber, the bands of one row being arranged in pairs and at substantially right angles to each other, and the bands of the other low being parallel to each other and disposed in close proximity to the angle of each pair of bands in the first mentioned row.

In a device for cooling air, the combination of a reservoir having a series of outlets, a depending bail beneath each series of outlets, a receiving chamber, and two rows of bands of absorbent tape having their upper ends connected to said bails and adapted to catch the drippings from said outlets, while the lower ends of said bands terminate within said receiving chamber, the bands of one row being arranged in pairs and at substantially right angles to each other, and the bands of the other row being parallel to each other and disposed in close proximity to the angle of each pair of bands in the first mentioned row.

In testimony whereof I afliX my signature in the presence of two witnesses.
