F. KONIG REFRIGERALxTING CHAMBER Filed Aug. 27. 1921 Patented Jan. l, 1924.
UNITED STATES FRIEDRICH KNIG, 0F MUNICH, GERMANY.
REFRIGERATING- CHAMBER.
Application led August 27,1921.
To all whom tmay concern:
Be it known that I, FRIEDRICH KNIG, citizen of Germany, residing at Munich, Bavaria, Germany, have invented certain new and useful Improvements in a Refrigerating Chamber (for which I have filed applications in Germany, August 21, 1917 England, August 20, 1917; France, July 9, 1920; Spain, October 428, 1920;- Austria, December 15, 1920; Hungary, August 14, 1920; and Czechoslovakia, July 8,1920) 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 usethe same.
This invention relates to refrigerating chambers of the type cooled by waterand having a lining of stone or earthenware or the like.
According to' this invention, the stoneware lining consists of plates attachedto a flexible material, such as cloth, guttapercha,l
thin metal or the like, and their edges are bevelled, at an angle of 45 to the face attached to the said material. This arrangement facilitates the insertion of the stoneware' into the box or chamber, and the backing of flexible material improves the insulation. The slabs may have ducts therein, as will be described hereinafter.
The invention is illustrated in the annext drawing, in which Fig. 1 is a vertical section of the refrigerator, Figs. 2 and 3 being sections on theline A-B of Fig. l, viewed from the bottom and top respectively.
The chamber shown comprises a double walled inner container, having walls a and al, between which the water flows.n This container is inside'a wooden box b, and between `it and the box walls there are contiguous stone slabs c attached to sheet or strip, or sheets or strips, of the exible material d; The edges of the slabs are bevelled .as already mentioned. In theconstruction shown all the slabs for the side walls and top are attached to one sheet, bentat e, the corner slabs fitting against each other as shown. The slabs for'the floor and back may be attached to another sheet. The bevelled edges form a network of channels f, containing air, and the inner container a alhas indentation It facing and enlarging these channels.v The slabs have ducts g therein, opening into ,the saidchannels and joined end to-end at the" corners. Watery serial v No. 496,574.
the chamber it passes off through a vent a3 arranged'in the top of the chamber inthe known manner.
The attachment of the slabs to flexible material facilitates the fitting of the slabs 'into the box, and-the air channels improve the cooling effect and keep the box dry.
It should be noted that a container z' for ice may lbe inserted into the lower part o'f the refrigerator. Thus partly.A by reason of the`completely surrounding water cooled walls of the refrigerator and the ice container, part-lyby reason of the stones, and further by reason of the air in the ducts f and g as well as in the ice container, a heat exchange occurs which causes further cooling of `the',contentsof the refrigerator. The valves lc `-,may be'op'ened according to the requirement to effect communication between the'air in the ice container and the air in the ducts f and g.
l/Vhat I 'claim is:
1. A refrigerator having alining of stoneware slabs lflexibly connected together and provided with bevelled adjacent edges, each slab being .further provided with an air duct communicating with the space between the said bevelled edges.
2. In a refrigerator, the combination of a provision chamber with through which water is circulated, of flex# ibly mounted stoneware slabs disposed about said walls, an air circulating space being providedgbetween the adjacent edges of the slabs and the walls, said air spaces'being are ,jacket having inlet and outlet openings at opposite ends, of a series of stoneware slabs disposed about said jacket, flexible material to which'said slabs are secured, said slabs being provided with bevelled edges cut at 45 degrees from the flexible Amaterlal out wardly to form airl spaces therebetween, each slab being provided with an air passage extending through fr/om opposite hollow walls v bevelled edges, whereby communication may be established between the spaces defined by the bevelled surfaces, a cooling chamber at one end of the refrigerator in communication with the air spaces, and valves disposed between the cooling chamber and the remaining portion of the refrigerator.
4. In a refrigerator, the combination of a water jacket in which the water is adapted to be circulated, the outside Walls of the jacket being provided with vuniformally spaced depressions, of a ller of stoneware slabs interposed between the water jacket and the Wall of the refrigerator, each Slat being provided with bevelled edges cut at 15 'communicating passage extending through from opposite faces of the bevelled edges thereof, the said passages being. disposed so 2c as tobe aligned with the adjacent passages of the other slabs.
In testimony whereof I hereunto aiiix my signature in the presence of two witnesses.
