COOLING DEVICE.

. To all whom it may concern:

Be it known that I, Mino W. BURKHAL- TER, a citizen of the United States, residing at Kerens, in the county of Navarro and State of Texas, have invented a new and useful Cooling Device, of which the following is a. specification.

Generally speaking, this invention belongs to the art of refrigeration, and it more particularly pertains to that class of devices ofthe `above art,'which employ an absorbent surface for absorbing and conveying a cooling'fluid from an upper level or strata `to a lower one. Vhile this process 'is being carried out, the warm air draft `which enters below the device, is cooled as it ascends.

The primary object of the invention is to provide a. device embodying the above method for cooling milk, cream or the like.

A further object of the invention is to provide a collapsible or knock-down structure, which when erected and supplied with an absorbent surface, as shown in Figure 1 of the "drawings, permits the above method 'to be successfully carried out. However, when in a knocked down or collapsed state, the parts thereof can be arranged'in a very small compass, in order to be shipped.

This device not only consists of the above principles, but also includes the characteristics of a refrigerator. y 1

Other articles `may be arranged in the refrigerator i or cooling device, than milk, cream and the like, for instance, meats, vegetables, and similar articles. ln the drawings, however, there is disclosed but one particular form of the invention, but in practical fields this form may require slight alterations, to which the applicant is ent-itled, provided the alterations are comprehended'in the appended claim.

Other features and combinations of parts will hereinafter be set forth, shown in the drawings, and claimed. f

In the drawings, Fig. 1 is a vertical sectional view through the cooling device or refrigerator, showing the various features of the invention. Fig. 2 fis a sectional view on line 2-2 of Fig. l. Fig. 8 is a horizontal sectional view on line 3-3 of Fig. l, with parts broken away 'in order to show further features in elevation. Fig. t is a view in perspective, showing the various parts of the cooling device or refrigerator in a knock-down or collapsed state, and arranged Specification of Lettersratent.

in a small compass, in such wise as to permit the same to be properly tied or secured together for the purpose of shipping. y

Attention is directed to the annexed drawings, in which the preferred form of the in'- vention is disclosed.

1 denotes the bottom supporting or base pan, from the four corners of which suitable legs 2 depend. Arranged within the pan adjacent the four corners thereof are sheet lmetal lugs These lugs 3 are'formed with.

extensions 11, which are folded parallel with the body of the said lugs. Between the extensions 1 and the body of the lugs the inclined uprights 5 of a frameare pivoted, which in Fig. 4, however, are shown collapsed and extended in opposite directions across the said bottom pan. These inclined uprights are approximately L-shaped in cross section and are supplied with obliquely arranged slots 6, the lower portions of which merge into the semioircular apertures 7.

Extending across the frame and arranged turned flanges 13, which are for the purpose of holdingthe'contents of. the shelves in` place. The shelves 11 are supplied with apertures 14,"through which passes the air, which enters the screened openings .15 of the base pan 1,'and finds its exit through the screened openings 16 of the upper pan l2. The screened openings 15 are surroundedby cylindrical sleeves or flanges 17, as shown-in Figs. 2 and 3. The openings 16are also surrounded by cylindrical sleeves or lianges, as shown at 18. The air which enters the openings 15 is considerably cooled as it ascends through the structure by way of the apertures 1i, when the cooling .fluid is descending by virtue of the fabric cloth or curtain 19, through the medium of capillary attraction. This fabric clothor curtain surrounds-the entire structure, and has its upper portion extending over the edge of the upper pan 12 and into the cooling fluidor liquid therein, as shown in Fig. 1. The Ycloth or fabric isV secured in this positin by :means -or cloth, the .depth of the fluid in the an.

of smallv hooks 20 which extend through the .curtain or cloth.

The cooling device or refrigerator is pro .vided with an automatic feed' for supplying i the upper pan 12 with water, which consists vposition' in the upper pan 12 with the open- A111g 22 adjacent `the bottom thereof in such a manner as to allow the cooling fluid 0r .liquid fo gradual ly -low fromthe tank. This it will do until'the depth thereof vreaches a level even with the top of the opening, 22', when thellow of liquid from the tank 1,2'1s cut oiffHowever, as soon as the coolingliquid or fluid is, absorbed by thecurtain 1,2 diminishes, and as this occurs the uid wthin'the tank-21'replenishes the pan 12. Whenthebase pan 1 becomes filled, the same vmay` bel emptied very'easily by removing thev ,screw plug24 shown in Figs. 1 and 4. By placing" a receptacle beneath orn connecting y"atube orv hose lto theilange opening, (with which the cap or plug 24 engages) the con- 31h-,tents ,of tlrelpan. lpmay be drawn ofil ,and dispose` Aof in any suitable manner. enthe Q Ooling lluid ,or liquid in the tank-is utilized o r'consumed, the same/may be again supplied by'removing the tank andallowing the -fluid to pass thereinto by way of the open` ing 22. The tankis again arranged in position as shown in Fig. 1, and the `absorption of the fluid is repeated by virtue of the cloth for. curtain. As the cooling iuidor liquid .descends by wayof the curtain or cloth, the

ascending airis not only cooled but is Vto 'a 'certain extent moistened; and as the liquid Vis descending there is `a very slight suction caused, which tends to draw the warm air through 'the screened openings 15, from below the pan 1.

By examining the annexed drawings, in connection with the above description, one may observe that there has been provided a novel form of cooling deviceor refrigerator, and one which may bequickly erected, or knocked down or collapsed. It will be observed that a device constructed along'these lines will fulfil n the various requirements and practical demands.

The upper pan 12' upon its longitudinal sides is provided with elongated sockets 26, which Areceive the upper ends of the Said angularly arranged uprights. In order to permit the ends of the uprights to be received by `said sockets one side of the L- shaped uprights are cut away, as shown in Fig. 4, as at 27.

The invention having been set forth, what is claimed as-newand useful is: j

In a .cooling device, theV combination with a base pan, lugs secured within its corners and each having an extension folded parallel l.with the body of the lugs, uprights of L- shaped cross section whose lower extremities are pivoted to said lugs and whose upper extremities have one side of the L. cut away, and an upper pan having sockets at its corners to receive said cut away portions, said uprights having obli uely arranged slots be# tween said pans; o wires engaging said slots removably, shelves having downturned flanges removably engaging said wires,`and'
