Specification of Letters Patent. Patented April 3, 1 9Q6. Serial No. 130,274. Divided and this application filed February19|i908l Serial No. 144,068-

Original application filed November 6, 1902,

To aZZ whom it may concern: Be it known that I, GEORGE W. WALLIoK, a citizen of the United States, residing at the city of Sturgis, in the county of .St. Joseph and State of Michigan, have invented certain new and useful Improvements in Refrigerators, of which the following is a specification. his invention relates to improvements in refrigerators.

The objects of the invention are, first, to provide an improved interior construction of refrigerator in which the parts may be readily and separably assembled, whereby the whole can be perfectly cleansed with a mini- In the drawings, taken looking in the direction ofthe little arrows at the ends of the section-lines, and similar letters of reference refer to similar parts throughout the several views. v

Referring to the lettered parts of the drawings, the. body of the refrigerator is I made up of the outer shell A and the inner shell A, of any suitable lumber or material,

the same being separated, so asto form hollow walls. The interior of the refrigerator is suitably lined with zinc, .as a, perfectly smooth and plain. The cover is alsol'provided with a suitable air-chamber. and the mum amount of labor; second, to provide usual packings around the same The door improved supporting means for the various is also made up of outer and inner walls to of refrigerators; third, "orm an air-chamber within and has a lining to correspond with the inner lining of the refrigerator.

In place of packing the walls of the refrigerator with a mineral material or sawdust or other non-conducting material I especially construct the same to secure thecirculation of the cold air within the same to distributethe cold evenly throughout. This I accomplish by dividing the air-spaces within the outer walls and door by a vertical partition halfway between the outer and inner walls A A, which entirely separates the air-space Within the hollow walls, making two distinct compartments. I then divide each of these airspaces by similar vertical partitions half-way between the central partition and the outer and inner walls. These partitions, however, are arranged at the top and bottom to leave an open space, the object of which is to insure circulation. With the air-spaces arranged in this way it is obvious that when the air opposite the ice-box within the airspaces becomes chilled. it will drop to the bot I tom, and in so doing the warmer air there will be displaced outwardly on the outside of the partition, and consequently a thorou h circulation which evenly distributes the co ld air is insured. The door is provided With similar partitions within its hollow walls, so that the same circulation occurs there. This insures an even and thorough airing of the whole interior wall of the refrigerator, so that consequently there is no sweating of the interior due to the circulation of air from a warmer part to a colder part, as very often occurs on the inside of refrigerators of the usual construction. This wall or casing 1 structure is fully described and claimed in to provide an improved construction and arrangement of the ice-supporting rack, drainage means, and traps for a refrigerator; fourth, to provide an improved means of dis- I tributing or circulating the air within the refrigerator.

Further objects will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification.

The invention is clearly described, and pointed out in the claim.

structure embodying the features of my invention is fully illustrated in the accompanying drawings, forming a part of this specification, in which Figure 1 is a detail vertical sectional view from the front to the rear of a refrigerator of my invention, l taken on a line corresponding to line 1 1 of Fig. 4, showing the details of arrangement of I the parts, construction of the drainage, and the trap. Fig. 2 is an enlarged detail perspective view of one of the supporting-standards' within the refrigerator, the flange for the ice-rack and upper parts appearing above with my adjustable shelf-support appearing below. Fig. 3 is a detail vertical sectional view taken on a line corresponding to line 3 3 of Fig. 2, showing the details of arrangement l of the connecting means for my improved shelf-support. Fig. 4 is a detail vertical sectional View taken on a line corresponding to 1 line 4 4 of Fig. l, the exterior casing being indicated in conventional form. Fig. 5 is a detail view taken on line 5 5 of Fig. 4 to show the relation of the parts.
