JONES YERKES, OF PI'IILADELPIIIA, PENNSYLVANIA.

IMPROVED REFRIGERATOR.

Specification forming part of Letters Patent N 0. 27,255, dated February 21, 1860.

To all whom it may concern.-

Be it known that I, JONES YERKES, of the city and county of Philadelphia, and State of Pennsylvania, have invented a new and useful Improvement in Refrigerators; and Ido hereby declare the following to be a full, clear, and exact description of the same, reference being bad to the accompanying drawings, and to the letters of reference marked thereon.

My invention consists of a refrigerator having four compartments, (each of the latter having an inlet and exit opening) an icechamber, and a cold-air chamber with a partition, the whole of the parts being arranged in respect to each other and to an air-space in the outer casing, in the manner described hereinafter, so that the whole of the chambers may be thoroughly and equally refrigerated.

In order to enable others to make and use my invention, I will now proceed to describe its construction and operation.

On reference to the accompanying drawings, which form a part of this specification, Figure 1 is a sectional elevation of my improved refrigerator; Fig. 2, a transverse sectional elevation on the line 1 2, Fig. 1; and Fig. 3. the same on the line 3 at, Fig. 1.

Similar letters refer to similar parts throu ghout the several views.

The body of the refrigerator consists of an outer casingA and an inner casing B, with an intervening air-space O, the whole being sup ported on suit-able legs D and being surmounted with a hinged lid E. The inside of the inner casing, as well as a portion of the under side of the lid, is coated with plates of zinc or other suitable material.

The interior of the refrigerator is separated into six compartments G and G, H and H, J and I. The compartment I, which is situated midway between the compartments G and G, has an orifice j communicating with the external air, and is arranged to receive the ice, which rests on a suitable grating 2'. Immediately beneath the latter is the coldair chamber J, situated between the two compartments II and II and communicating with the drip a, which is furnished at the bottom with the usual bent tube or with any other device which will serve as a trap to allow for the escape of the waste water, and at the same time prevent the air from entering. Each of the chambers G and G has a suitable hinged lid, has an opening 1) near the top communicating with the air-space 0 between the two casings of the refrigerator, and an opening 0 at one of the lower corners communicating with the cold-air chamber J. Each of the lower chambers has an opening d near the top communicating with the air-space O and an opening a near the bottom communicating with the cold-air chamber J. Access is obtained to both of the lower chambers through openings in front furnished with suitable doors, and each chamber is furnished with a grated ledge f, on which to deposit the dishes, 850., containing articles of diet.

The ice havin been deposited in the chamber I and all the doors of the refrigerator bein g closed, the external air will enter through the tubular opening j and will descend through the body of ice, and being thoroughly cooled by the latter will pass through the grating t' into the cold-air compartment J, from whence the cold air will pass into each of the chambers G and Jr H and H, entering near the bot-tom of each chamber, circulating through the interior, and finally passing into the air-space C, from which it escapesthrough an opening 70 at the back of the refrigerator into the external atmosphere. It will now be seen that by the above-described peculiar arran gement of compartments and communicating openings each of the chambers G and G and H and H will be thoroughly and equally refrigerated. It will also be seen that the body of cold air contained in the space 0 will tend as a non-conducting medium to prevent the warm external air from detracting from the coolness of the chambers. The object of the partition h in the compartment J is to direct an equal flow of cold air to each of the chambers H and H and to prevent the air in one chamber from commingling and interfering with the free circulation of the cold air in the other chamber.

Iwish it to be understood that I do not claim, broadly, the employment of a double casing with an intervening space for the passage of the cold air,nor do I claim any of the parts independently of the specific arrangement of the whole; but

I claim as myinvention and desire to secure by Letters Patent The upper chambers G and G, with their respective openings 1) and c, the lower cllam- In testimony whereof I have signed Iny hers H and H, with their respective openings name to this specification before two subscrlbd and e, the ice-chamber I, and the cold-air ing Witnesses.

chzunber J, with its partition h, the whole of JONES YERKES. the above-mentioned parts being arranged in Witnesses:

respect to each other and to the air-chamber HENRY HOWSON,

O as and for the purpose herein set forth. I CHAS. E. FOSTER.
