M. A. SNIDER. ICELESS REFRIGERATOR.
APPLICATION FILED AUG.5, I920.

' IGELEBS REFRIGERATOR.
Specification of Letters Patent.
Patented July 19, 1921.
Application flled August 5. 1920. Serial No. 401,327.
To all whom it may concern Be it known that I, Mwron A. Sworn, citizen of the United States, residin at Detroit, county of Wayne, State of Michian, have invented a certain new and useful mprovcment in Iceless Refrigerators, and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawing, which form a part of this specification. y invention relates to an improvement in so-called iceless refrigerators in which the interior of the food chamber is cooled through the rapid evaporation of the moisture with which the walls of the refrigerator are charged.
One of the objects of my invention is to provide adevice comprising a plurality of sections, the respective sections being adapted to be brought into abutting relation, whereby the capacity of the refrigerator may be either increased or reduced to meet the requirements of the purchaser.
A further object is to provide a device which may be readily moved from one location to another an being constructed in sections, it may be more easily handled without danger of breakage :-the walls of the device being constructed of a relatively fragile and porous material.
A further object of the invention is to provide for the reinforcement of the several sections that they may not be easily broken through handling.
Another object of the invention is to provide means whereby the abutting portions of the refrigerator may interlock, thereby avoiding accidental displacement.
Another feature of the invention consists in providing the device with a plurality of wire shelves supported upon ledges formed in the wall of the device to receive articles of food within the coolin chamber.
With the foregoing an other objects in view which will appear as the description proceeds, the invention further resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes may be made in the precise embodiment of the invention herein disclosed without departing from the spirit of the same.
In the accompanying drawings forming part of this specification e- F gure 1 is a side elevation of the device.
Fig. 2 is a plan view of a lower section of the cooling chamber taken on or about line 2-2 of Fig. 1.
Fig- 3 is a vertical cross-sectional view taken on or about line 3--3 of Fig. 2.
Referring now to the letters of reference placed upon the drawings,
A, denotes a cooling chamber constructed of a suitable porous earthenware material adapted to readily absorb moisture; The chamber A, is preferably constructed of a plurality of superimposed sections A, formlngga single unit of suitable capacity.
indicates a cover formed of similar material to that employed in the lower sections. B is a knob or handle to provide for the ready removal of the cover. 0, indicatcs Wire or other reinforcing material embedded in the wall of the chamber, and in the cover, to give strength to the structure and to insure it against accidental fracture.
D, denotes a tongue projecting from the edge of each section of the device adapted to fit into a corresponding groove in the adjacent section to secure the parts against accidental displacement. The tongue D, as shown in Fig. 2 projects upwardly from only one half of the wall of the chamber it may, however, be a continuous ring completely encircling the section, if desired.
E, denotes wire shelves supported upon a ledge formed in the wall of the respective sections A.
F, F, F, indicate elastic bands, respectively supported in' a peripheral groove formed in the wall of the several sections the walls of the bands being spaced from the wall of the chamber to provide an annular trough in which water may be lodged to supply the walls with suflicient moisture that .the interior of the chamber may be cooled through the evaporation of the water contained in the walls.
Having now indicated the several parts by reference letters the construction and operation of the device will be readily understood.
The walls of the several sections are first immersed in water until the walls of the chamber are properly charged with moisture. The sections are then arranged in superimposed relation, as shown in the drawings, and the food placed therein on the respective shelves. The device is then placed near a window or where a current of air will insure the evaporation of the water contained in its walls, perature in the chamber. walls may be supplied with water to take the place of the water evaporated, the several annular troughs are filled with water from time to time, thus providing for the continuous operation of the device.
aving now described my invention what I claim is:
1. In a device of the character described, a vessel formed of porous earthenware adapted to absorb moisture,'and a plurality of removable troughs surrounding said chamber adapted to receive water, whereby the walls of said device may be supplied with moisture. 2. In a device of the character described, a vessel formed of porous moisture absorbing material, and a plurality of elastic rubthus reducing the tem-. In 'order that the ber bands having one edge lodged in grooves formed in the wall of said device and with an upstanding wall spaced from the wall of the vessel to form a water trough, whereby the porous walls of the vessel may be supplied with moisture.
3. In a device of the character described, a vessel formed in sections adapted to be superimposed to form a single chambered unit, the walls of the respective sections formed with a tongue and groove connection, a plurality of removable L-shaped elastic channel members respectively supported in a peripheral groove formed in the wall of each of the several sections, and a cover for closing the openin into said vessel.
In testimony whereo I sign this specification in the presence of two witnesses.
