REFRlGERATOR.

SPECIFXCATON forming part of Letters Patent N o. 677,380, dated duly 2, 1901. Application led January 10,1901. Serial No. LiZf/Stl. (No model.)

To @ZZ whom it' may concern.-

Be it known that I, WILLIAM THOMAS, a citizen of the United States, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented neuT and useful Improvements in Refrigerators, of which the following is a specification.

My invention relates to refrigerators, and contemplates the provision of a refrigerator embracinga simple and inexpensive construction calculated to insure the constant circulation of dry cold air from an ice-chamber through a cooling or refrigerating chamber and thence back to the ice-chamber.

Other advantageous features of the invention will be fully understood from the following description and claim when taken in conjunction with the annexed drawings, in

Which- Figure l is a vertical longitudinal central section of a refrigerator embodying my invention. Figs. 2 and 3 are transverse sections taken in the planes indicated by the broken lines 2 2 and 3 3, respectively, of Fig. 1.

In the said drawings similar letters designate corresponding parts in all of the several views.

The casin g A of the refrigerator, Which may be of any suitable shape, preferably comprises the usual inner and outer walls a and an interposed lling b, of suitablenon-conducting material, It incloses an icecham ber B and a refrigerating or cooling chamber O and is provided With doors D E, the former opening into the refrigerating-chamber, so as to permit of the ready introduction and removal of food products, and the latter communicating with the ice-chamber, so as to admit of the supply of ice being replenished Whenever necessary. v

The ice-chamber B is located at the upper portion of the end of the casing remote from the door D and is formed by the side and top Walls of the casing, in conjunction with a transverse vertically-disposed and imperforate Wall c, which divides the ice-chamber from the refrigerating-chamber, an imperforate bottom wall CZ, and a transverse vertically oblique Wall e, the latter being arranged adjacent to the end Wall of the casing and being of openwork construction, so as to enable it to retain the ice in the chamber and permit of the passage of cold air, as presently described.

`As best shown in Fig., 1, the bottom Wall CZ of the ice-chamber B is extended beyond the Wall e, as indicated by f, and is provided with a depending lip g, which overhangs the adjacent side Wall h of a transversely-dis posed trough F. The said trough is preferably of metal and is passed through an opening in one of the side Walls of the casing after the manner shown in Fig. 3. By virtue of this construction the Water formed by lnelting ice is quickly deposited in the trough F and carried by the same out of the refrigerator, which is advantageous, since it insures the dryness of the air subjected to the cooling action of the ice and prevents the same being laden with moist-ure prior to its passage into the refrigerating-chamber C.

Gis a passage or opening formed in the top Wall of the casing A, above and in communication with the icechamber B. This passage is provided for the entry of atmospheric air and is normally open, so as'to en= able the ice to draw such air into the refrigerator.

`H is a fine which is arranged adjacent to the top Wall of the casing and is preferably of a Width corresponding to that of the interior of the casing, as best shown in Fig. 3. The said flue H communicates atone end with the upper portion of the icechamber B and extends therefrom to a point adjacent to the end Wall of the casing remote from the icechamber. Itis designed to receive the air after it has passed through the refrigeratingchamber among the food products therein and become more or less heated and conduct it back to the cooling-chamber.

In the practical operation of my improved refrigerator the ice in the chamber B draws atmospheric air into the said chamber through the conduit or passage Gr. This airis cooled by the ice in chamber B and descends through the open-work Wall e and passes between the Y extension f of Wall CZ and the trough F into the refrigerating-chamber C. Here it circ'u lates among and refrigerates the food products placed in said chamber C, and when it has become more or less heated by its contact with said products it passes up into the ue H and.

as soon as it is formed by melted ice is an important feature of my invention, since it prevents the air being laden with moisture and` insures the passage of dry cold air only through the refrigerating-chamber.

I prefer to employ the passage or conduit I in my improved refrigerator, since 'the entryof fresh air into the ice-chamber and its subi sequent passage into the refrigerating-chamber renders the latter at all times pure and wholesome. I do not desire, however, to be understood as conning myself to the use .of passage G, as when it is omitted a constant circulation of dry cold air through the refrigerating-chamber will be maintained.

Notwithstanding its advantages, as above pointed out, it will be observed that my improved refrigerator is sixn ple and inexpensive in construction. It will also be observed that the refrigerating-chamber is of large capacity, while the chamber necessary to hold a sufficient amount of ice is comparatively small.

Having thus described my invention, what I claim is- In the refrigerator described, the casing containingarefrigerating-chamber and anicechamber, thelatter being located in the upper l portion of the casing at one end thereof and formed by the imperforate upright Wall arranged adjacent to the refrigerating-chamber, the open-work upright Wall e arranged remote from the refrigerating-chamber, and the imperforate bottom wall extending between the walls c and e and having the depending lip g at its edge remote from the refrigerating-chamber, the transverse trough arranged below the bottom wall of the icechamber and so that one of its walls is overhung by the lip g of said bottom wall, and a passage for air is formed between it and said lip; the said trough extending throughout the Width of the casing and outside the same so as to carry oft water as soon as the same is received from the ice-chamber, and the iue arranged adjacent to the top of the casing and communicating at one end with the upper portion of the ice-chamber and extending therefrom to a point adjacent to the opposite end of the casing whereby it is adapted to receive air from the upper corner of the refrigeratinga chamber and thereby insure the circulation of air throughout the length of said refrigerating-ehamber, as specified.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.y
