Improvement. in Refrigerators.
No.133,147.. rr/fw- J. HYDE FISHER, on
CHICAGO, ILLINOIS.
iiVIPROVEviENT IN REFRIGERATORS.
Specification forming part of Letters Patent No. E33,/7, dat-cd November 19, 1872.
To all whom it may concern:
Be it known that I, JosErH HYDE FIsHER, of Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Refrigerators, of which the following isa specification:
This invention relates to a new and useful improvement in refrigerators, having particular reference to a refrigerator for which Letters Patent of the United States were granted me, dated August 1, 1865, and reissued the 31st day of January, 1871, which present invention consists mainly in an air-space beneath the icechamber, arranged as hereinafter more fully described.
-In the'accompanyin g drawing, Figure l is a vertical longitudinal section of the refrigerator taken on the line w x of Fig. 2. Fig. 2 is a vertical cross-section of Fig. 1 taken on the line y y.
Similar letters of reference indicate corresponding parts.
A represents the ice-chamber or compartment. B B are compartments provided with shelves for refrigerating and preserving fruits, provisions, and other articles. The walls of the refrigerator are made double, and filled with non-conductin g material, as indicated in the drawing. The main features which distin guish my refrigerator from oth er inventions for a similar purpose, as well as the mode of constructing it and arranging the chambers, &c., being minutely described in my said reissued Letters Patent, require at this time no particular description; suflice it to say that my improved refrigerator is provided with a double bottom, A, between the ice-chamber and the refrigerating or provision chambers, the lower portion of the bottom being of wood andthe upper portion being metal, as seen in the drawing. Between these two parts is the air-space C, which constitutes my present invention. The circulation of air within the re` frigerator is indicated by the arrows. D is an air-channel directly'back of the ice-chamber, which is in communication with the chambers B B. The cold air descends from the ice-box through the openings E into the chambers B B, as indicated, and forces the warmer air in those chambers upward through the channel D, and in contactwith the ice, from whence it aga-in descends. The circulation is maintained by the specific gravity of the air, the cold air constantly descending and displacing the warmer air below. The air-space C, being separated from the ice by only the metallic portion of the double bottom, the air therein partakes of the temperature of the ice, and assists in keeping up the circulation. In this space there is a series of longitudinal slats, F, upon which the upper or metallic portion of the bottom rests, which divide the space C into four (more or less) longitudinal channels, running the entire length of the bottom and communicating with the coldair openings F at each end of the refrigerator. Gr G are metallic pieces secured at the front and rear, which support the double bottom. These pieces extend down into the provision-chambers below the bottom, and thereby conne the warm air and compel it to ascend through the rear challnel D to the ice-chamber, as stated. I is the waste-water pipe, placed in the vertical r`partition which separates the provision-chambers. J represents a cake of ice in the ice-chamber.
Refrigerators with this improvement may be made of any size, and with a different arrangement of the chambers to suit the various purposes for which they may be'required.
Having thus described my invention, I claim as new and desireto secure by Letters Patent- The ice-chamber A and provision-chamber B, connected by separate passages D E, combined with the intermediate air-chamber C, opening into downward channel E, and with the supporting-pieces Gr G, as and for the purpose described. I
