WILLIAM E. WHITE, OF NEIV YORK, N. Y.

REFRIGERATOR.

SPECIFICATION forming part of LettersJPatent No. 424,392, dated March 25, 1890.

Application filed May 31, 1888. Serial No.275,606. (N0 model.)

To all whom it may concern:

Be it knownthat I, WILLIAM E. WHITE, a citizen of the United States of America, residing at New York, in the county of New York and State of New York,have invented certain new and useful Improvements in Refrigerators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

My invention relates to refrigerators; and it consists in the improved construction hereinafter described and set forth.

In the accompanying drawings, Figure 1 is a vertical sectional view of a refrigerator or cooling-room constructed in accordance with my improvement. Fig. 2 is a top view, a part of the bottom slats beingbroken away to expose the drip-troughs. Fig. 3 is a detail view.

A refers to one of the vertical walls of the refrigerator; B, the sides; 0, C, and C the front; D, the top, and E the bottom.

The back wall A, side walls B, bottom E, and front 0 O are formed with double walls, so as to be practically non-conducting, the space between the inner and outer walls of the aforesaid parts being packed with suitable material.

The top D and inclined portion 0 of the refrigerator, when small cases are built, may be made of glass, though when large refrigerators are provided these parts are made of wood in the ordinary manner.

One of the sides B is provided with doors through which access can be had to the provision-chamber, and a door may also be pro Vided for the ice-chamber.

I prefer to construct the portion 0' of the front so that it will incline upwardly, as shown in Fig. 1, so there will not be at that portion of the refrigerator any sharp corners to obstruct the upflow of warm air and at the same time contract the portion of the refrigerator where the ice-box is located.

The ice-box F is provided near the front with a vertical wall G, which extends nearly to the top D, to provide a vertical flue H, through which the warm air will pass up* wardly and over the upper edge of the wall G into the ice chamber. The opposite side of the ice-chamber G is formed of a series of slats, which are attached at their upper ends to a horizontal strip g, while their lower ends are secured to a metallic angular plate Lwhich extends across the refrigerator and forms a portion of the drip-trough. To the sides of the ice-chamber are tacked vertical strips 1' i. This construction provides on one side of the ice-chamber a flue H and on the opposite side a flue H.

Above the drip-troughs, as will be l1ereinafter described, rests the bottom of the icechamber, which is made up of a series of slats J,wl1ich have blocks j attached to their sides to keep them separated from eachother. The central slat is provided with blocks on each side of the same, so that when the slats are properly placed in the bottom of the ice-chamher they will be equidistant from each other. The sheet-metal strip Lwhich forms a portion of the drip-trough, is supported upon transverse strips Z and Z, and opposite thereto is a similar metallic lining I of greater Width, which is supported on strips m and m',which rest upon a metallic strip secured to the sides B B of the refrigerator-frame. Between these strips I and I are secured inclined strips M, covered with sheet metal. The ends of these strips I, I, and M lie over the drip-troughs N N, which are formed to provide gutters, and are provided with openings above the pan 0, which lets into a drip-pipe P.

In a refrigerator constructed as hereinbefore described, when ice is placed in the icechamber, the cold air will pass out of the open sides into the flue H and descend into the provision-chamber, while the warm air will rise in the flue H, pass above the same into the ice-chamber,and there become cooled. At the same time this air is being cooled by passing over the ice the impurities carried upward from the provision-chamber will be taken up by the ice and carried off with the melted ice into the drip-trough and out through thewastepipe.

In a refrigerator constructed as hereinbefore described there is no condensation, or at least no condensation will settle upon the inner sides of the refrigerator, thus showing that there is a circulation of air in the refrigerator which will better preserve the contents of the provision-chamber and all odor is carried off through the waste-pipe.

lhe sides or outer casing of my improved refrigerator are made up of, first, an interior lining of wood, to which is suitably secured a lining of three-ply resin-sized paper. The space between this and the outer walls is filled with sawdust from cedar wood, and then there is another lining of paper and wood, the exterior being finished with any hard wood to suit, thus making a lining having three thicknesses of wood, three of paper, with a space-filled with sawdust, making a positively-tight nonconducting wall which will always remain sweet. The resin-sized paper and the sawdust give it an odor and keep the walls sweet.

The shape of the gutters, which are shown in the accompanying drawings in their preferred form, does not form obstructions to the cold air, but permits it to descend into the provision-chamber.

It will be observed that the hereinbefore- I described refrigerator is not provided with any openings connected with the exterior to superinduce the circulation of air, said circulation being induced by the construction and arrangement of the parts, and the air in the provision-compartment being kept comparatively dry, moisture being carried off with the waste water, articles will be preserved and any odor given off from one article will not be imparted to others in the provision-chamber; but the odor will be carried upward with the hot air and absorbed by the ice and commingled with the waste water from the melted ice and carried out of the refrigerator through the waste-pipe.

The ice-box can be 7 readily cleaned by removing the slats J and the bolsters or supports K, upon which they rest, and when removed access can be readily-had to the gutters for cleaning them.

What I claim as new, and desire to secure by Letters Patent, is

A non-conducting wall for refrigerators and the like, consisting of an exterior double sheathing of wood, a lining of resin paper covering the inner surface of each layer of said double sheathing, an inner sheathing of wood arranged at a distance from the outer sheathing and having its outer surface covered with resin-paper, and a packing of cedarwood sawdust to fill the space between the inner and outer sheathings.

In testimony whereof I affix my signature in presence of two witnesses.
