IMPROVED REFRIGERATOR.

' The Schedule referred to these Letters Patent and making part of the same.

Be it known that Ii'RoBERT S. GODFREY, of Philaa full, clear, and exact description 'of the same.

lily-'invention consists of a refrigerator, so constructed and arranged that the provisions or other articles to be preserved shall be separated from the ice, and thus protected iifom darnpness, but shall be so surrounded by or brought in contact with chilled-metal surfaces, that the said provisions, 85e., shall be maintained atthe low temperature `t'equired'; all of which is fully described hereafter.

In ordern toenabletsth-ers"nnuaire' and use "my in` vention, I will now proceed to *describe the mode of constructing and using the saine, reference beinghad to the accompanying drawing, which forms a part oi" Figure l is a vertical sectional view of my improved Figure 2, a sectional plan view of the same, on the A. represents a wooden chest, or box, mounted upon feet a, and having in front an opening, to which is adapted a hinged door, B, provided with a knob, or

Within the chest A is a thin -metal casing, F, which may, ifdesired, be of smaller size than the interior of the said chest, so as to admit of the intervention of some non-conducting packing between the two.

A vertical partit-ion, d, of this casing'F, divides the interior of the refrigerator into two compartments, a chamber, H, in front, and a narrower chamber, or reservoir I, at the back of the refrigerator, for the reception of icc The ice is introduced into the reservoir I through by a lid, in, the latter, as well as the door B,- being faced with metal on its inner side.

Hollow extensions j, j l, and jz, of the casing F, which communicate with the interior of the ice-reservoir-I, form the top and bottom of the chamber H', and a of the upper extensions j and jl, may, if thought necessary, be slightly inclined toward the reservoir'l, so as to prevent any water from accumulating in them from the melting ice.

The reservoir I-should also be provided, at its lower end, with a suitableeock for drawing ofi' the water, from time to time, as it; accumulates.

'lhe provisions other articles to be preserved are introduced into thechambcr H, after opening the door B, and are placed iibon the shelf j l and bottom ji, or on suitable gratings resting on the same.`

It should here be understood that the number of hollow shelves within the chamber H may be increased, as required, according according to the capacity of the' refrigerator.

0n filling the reservoir I with ice, the partition d and the hollow extensieiis j,j, and ji, 'are qugieklyehiued, l

andthe air within the chamber H, by'contact with these chilled surfaces, is thoroughly cooled, andis maintained at as low a temperature as is required for the preservation of the meats and other articles of diet which have been placed in the said chamber H.

One of the advantages possessed by my invention is, that the ice, being'contained in a separate compartment, is not exposed to the external air when the door is opened, as in ordinary refrigerators, and therefore last much longerwithout inciting.

Another advantage being that the provisions, Sac., are kept perfectly dry, as they are not exposed' to the vapors arising from the melting ice, but are maintained Aat as low a .temperature as is required by the extended cooling-surfaces by which they are surrounded, and with which, if desired, they may be brought in contact.

I do not claim, broadly, oue or more narrow casings I In testimonyavhereof, I have signed my name to this speciiication, in, the presence of two subscribing wituesses.
