BENAIAH FARNUM, OF KEOKK, IOWA.

REFRIGERATOR.

SPECIFICATION forming part vof Letters Patent No. 241,853, dated May 24, 1881.

Application filed May 29, 1576.

To all whom it may concern:

Be it known that I, BENATAH FARNUM, of Keokuk, Lee`county, Iowa, have invented a new and useful Improvementin Refrigerators.

VIt is made substantially as set forth hereinaf- 1 for cooling it and the contents, and in various details of the apparatus.

The walls A are made hollow, of. wood or other material, with air-spaces B between the inner and outer shells. These spaces in the back and front sidesare closed all around.

In the two sides, C D, and the' top and bottom- E F these spaces connect, so as to pass entirely around the center space or chamber, G, having the lateral edges closed. /The six flat walls are made separate. Their edges are made to t closely by being slightly concave, Into the joints a packing-strip' of flannel, a cord, or other material, is put onto one part to make the joint secure and close irregularities. The bottom F has curtain-edges and supports and a raised edge to set the upright` sides inside of. The side Walls, front, and back are set onto the bottom, inside the raised edge; The front and back overlap the sides, and are secured to them solidly byheavyserews or screw-bolts at H H. The top E overlaps all the upright parts. The top and bottom are secured by screws, butmay be 'used Without. The front has a large door, and in that a smaller door, for use as required. Racks are placed on the side walls. On these ,are mounted suitable sliding racks, K,\ which are drawn forward or pushed back, as desired; or shelves may be used instead to hold the articles required.

The ice is placed in box L, which rests in bearings in the top of chamber G, so as to slide in and out. This has a rack-bottom to hold the ice suspended, and a trough-bottom to convey off the water, which discharges by a pipe at the back. Between the rack and bottom are openings in the sides to leta stream of air pass down through the ice.

The fan M is mounted on one sideof the refrigerator, and turns by friction or other gearin g, operated by hand, spring, or other power. This fan is connected with chamber G by passage N, so that a stream of air can be drawn out by-the fan, and connects with the space B by passage N', so as to force the stream around this passage and through the ice-box L at the top by downward opening P, so as to cool the air and the contents ot1 the refrigerator by the circulation.

The refrigerator can be ventilated by forcing a stream of air by the fan out by passage B and outer opening, R, drawing in by opening S. These openings have stop-covers, which can be pnt on and secured in place. When thus` ventilating the coveris taken from passages R S audit is put into the opening It, as shown'b'y dotted lines, so 'as to turn the air outward' and stop it downward.

I claim- 1. A refrigerator having its outside walls in sections removable to pack in smaller space for shipping, and with joints and passages so arranged as to fit together and to form air-pas.- sages within the walls from one section to another, substantially as set forth.

2. In a refrigerator, the combination of icechamber L, refrigerating-chamber Gr, air-forcing apparatus M, air-passages IW, and outside walls formed in iiat separable sections, arranged snbstantially as set forth.

3. In a refrigerator, the combination of several tia-t sections, made each'separable from the others, and vwith edge joints and bearings, arranged to fit together and form the several sides ot' a refrigerator air-tight, substantially as set forth.
