Application filed February 13, 1914. Serial No. 818,550.

To all whom it may concern:

Be it known that I, GEORGE E. Coxn, a citizen of the United States, and a resident of Santa Rita, in the county-of Grant and State of New Mexico, have invented an Improvement in Refrigerators, of which the following is a specification.

My present invention relates to refrigerators and more particularly to that type of refrigerators generally known as iceless refrigerators in which the lowering temperature is obtained upon the. principle of evaporation of liquids, my object being to provide a refrigerator of this character embodying certain novel features of construction and arrangement whereby a maximum evaporation may be obtained and a thorough circulationmaintained at all times and'whereby certain other advantages to be hereinafter described may be gained in order that a high degree of effectiveness may be present at all times.

The accompanyingdrawings illustrate the various details constituting one form of the embodiment of my invention and will be hereinafter referred to in order that they may be thoroughly understood and in order that the advantages arising therefrom may be thoroughly appreciated.

In these drawings, Figure l is a vertical section taken through the complete refrigerator substantially on line 1-1 of Fig. 2. *ig. 2 is a plan view with the cover removed. Fig. 3 is a horizontal section taken therethrough substantiallyon line 33 of Fig. 1. Fig. 4. is an enlarged vertical section from the forward portion of the refrigerator taken substantially on line 44 of Fig. 3. Fig. 5 is a horizontal section taken on line 5-5 of, Fig. 1. Fig. 6 is a plan view of one of the doors. Fig. 7 is a whole perspective view of one of the capillary curtains removed. F ig. 8 is a vertical transverse section taken on line 8-8 of Fig. 1. Fig. 9 is an elevation of a portion of one of the inner walls. Fig. 10 is a perspective view of one of the capillary pans. Fig. 11 is an enlarged section through one side of one of the capillary pans with its capillary members in position. Fig. 12 is a whole perspec tive view of one of the sup orting brackets for the capillary pans. Fig. 13 is a perspective view of a fragmentary portion of one of the capillary holding plates.

Referring now to these figures, theframe of my improved refrigerator consists of a body A, the side, front and rear walls of which are provided with openings, the openlngs of the side and rear walls being covered by suitable reticulated material such as for instance the screens A as best shown in Figs. 1 and 3. The base of the body A is also open and is substantially uncovered to assist in promoting a thorough circulation of air through the entire body, although this base as well as the rear wall may be pro vided with supporting stiles G and a, respectively, extending across the openings thereof. The top of the body is closed by a cover A upon which may be mounted a suction fan B for promoting a forced circulation and the flaring suction nozzle B of which is extended inwardly through the cover at a point substantially central between the side edges thereof for a purpose to be hereinafter described.

Mounted in the upper and lower portions of the body A and at various intermediate portions as desired are a plurality of capillary pans which divide the body horizontally. Inthe present embodiment I have shown upper and lower pans C and C and an intermediate pan C centrally between the upper and lower pans so that the body is divided into upper and lower horizontal chambers of which the lower chamber forms an enlarged food compartment D. The upper chamber is divided by spaced vertical walls E located at a point substantially central between the sides of the refrigerator body and forming an air flue open at its lower end into the lower enlarged food chamber D. This air flue thus divides the upper chamber vertically into juxtaposed food chambers D and D and is provided with lateral openings eat an intermediate point communicating with said food compartments Dand D The upper end of the fiueE is also open and is directly below the suction nozzle 13 of the fan when the cover A is in position as clearly seen by reference to Figs. 1 and 8.

These food compartments D, D and D are each surrounded by inner walls F, these inner walls being spaced from the walls of the body sufficient to form surrounding air spaces between them, and the walls of the upper compartments 1) and D being utilized'to support the upper capillary pan 0.

The intermediate capillary pan 0 is supported upon corner brackets 0, one of which is shown in detail in F 1g. 12, each of the brackets having bayonet slots engaging bolts fixed to the body A in order that they may be readily removed. The lower capillary pan C is supported upon the stiles G and also upon a surrounding flanged bar G the upper portion of which supports the tray H which in turnsupports the walls F of the lower food compartment D. Trays H sup ported upon brackets h, in turn support the walls F of the upper compartments D The intermediate capillary pan C is also supported upon intermediate cross bars 0 as shown in Fig. 1 these bars being removably supported at their ends in brackets 0*.

The inner walls F of the several food compartments are formed of plates the side edges of which are hinged as best shown in Figs. 3 and 9, these plates having vertical series of apertures with outwardly and downwardly inclined integral lips or projections 7 and certain of the walls of the upper food compartments adjacent to the sides of the flue E may have openings f as shown in Fig. 9 in order to communicate directly with the lateral flue openings e before mentioned.

Each of the capillary pans C, C and C the former of which is shown in detail in Fig. 10, is provided with side openings of the same size and a relativelysmaller central opening and is further provided with troughs 0 surrounding the several openings and in communication with one another to receive a supply of liquid as best shown in Fig. 11, the side openings of each of the pans being covered by flexible capillary curtains I stretched thereover, the edges of which curtains depend into the troughs c and the central openings of the upper and lower capillary pans C and C are also covered by curtains I. the edges of which are extended into the troughs in like manner. Similarly capillary curtains I are extended vertically upon all sides of the several food compartments upon the outside of their inner walls F, the upper and lower edges of these capillary curtains I being also extended into the troughs of the capillary pans above and below the same.

In this manner the several food compartments are entirely surrounded by moisture carrying curtains through which the air circulating through the food compartments is drawn in order to set up the desired evaporation and thus causing lowering tempera- V ture.

V The edges of the several curtains extending into the troughs of the several capillary pans are preferably held by frames or plates J, the side walls of which depend into the troughs and are provided at their lower edges with spurs or projections j engaging the curtain edges as best shown in Fig. 11.

Each of the capillary pans is also provided with a depending outlet tube 0 to which is connected one end of a flexible pipe 70, the opposite end of which is connected to a valved drainage fitting is communicating with a vertical drain pipe K depending upon one exterior side of the refrigerator body whereby the several pans may be drained and cleaned when desired.

Surrounding the intermediate capillary.

The openings of the front wall of the body A have beveled edges as best seen by reference to Figs. 3 and a and receive the doors N which are identical except as to size and are provided with similarly beveled edges. These doors have openings covered by screens N similar to the screen covered openings of the body walls has a surrounding bracket n extending inwardly therefrom and to which is secured a vertical plate N having apertures and outwardly and downwardly projecting integral lips 41, these plates being adapted to set into and form parts of, the adjacent inner walls of the respective food comand each door partments and also having vertical capillary curtains N into the upper and lower'edges of which are secured stiffening wires a these curtains being adapted to contact at their stiflenededges with similarly stifiened edges of short curtains N extending'into the troughs of the capillary pans. V

The several food compartments may have any number of intermediate trays one of which is indicated at .O in the food compartment D and is shown as supported upon lugso, projecting inwardly from the side walls. The supplementary liquid holding tubes L maybe supplied withfiuid through filling apertures to which funnels and the likeZ are attached.

Thus it will be seen that each of the sev- V eral food compartments into which the body of the refrigerator is divided are surrounded by air spaces in direct communication with the exterior of the refrigerator through its screen covered wall and door openings, and with moisture holding capillary members receiving a constant supply of liquid and through which air is drawn to effect a circulation within the refrigerator.

It is also to be noted that the inner walls of the several food ctunpartments support forced edges contacting the depending curtains in proper relation due to their integral lips or projections f and the projections '12, and that these projections serve to return to the capillary curtains any excess moisture dropping from above. 1

The circulation is constant through the entire refrigerator by means of the suction fan B and all odors are promptly removed from the food compartments, thus rendering the refrigerator sanitary in a high degree and continuously effective in its operation.

It will also be noted that the entire refrigerator may ing the cover A and successively lifting out the several capillary pans, the curtains and the inner walls and troughs of the several food compartments.

It is also to be noted that the several capillary pans may be drained and cleaned without necessitating their removal, by means of the drain pipe K and its valved drain fittings communicating with the depending outlets on the pans as before described,

By the use of a refrigerator of this type a desirably low temperature may be obtained without the use of ice and with the added advantage of a continuous circulation of fresh air and discharge of odors from the various foods stored therein.
