To all whom it may concern: find itv able to arrange said openings 9 Beitknown thatI, CHARLES C. LocKsrAnDr, in the; ill of the refrigerator just over a subject of the Emperor of Germany, residsuch cl r occupied by the bibulous ma- 55 ing at Chicago,in the county of Cook and State terial l will be understood, of course,

The refrigerator box or chest shown in said The chest is provided at the bottom drawings, broadly considered, is of ordinary there@ h an outlet pipe 10 that passes construction and shape, having an ice-chest throug e front wall of the refrigerator and So 1 extending down into the box at about the is pro l with a faucet 11 by means of 3o middle thereof, and open at the top. A door which water may be drawn off. Within 2 hinged to the top of the box closes the said the ici st an ice-pan 12 is located having ice chest as shown. A series of holes or openfeet 1l means of which it is supported ings 3 are made along the upper portion of upon il Iottoni of the ice chest. The ice is 85 the ice-chest for the passage of cold air from placer; he ice-pan in the bottom of which said ice-chest to the refrigerator boX.

In accordance with the principle comprised The r preferablyconsists of a perforated 9e by my invention the top, bottom and side bottoi` to said ice-pan, a layer 15 of felt 4o walls of the refrigerator box, and the doors or ant )us material upon said perforated f 2 and Lt, consist of an outer layer 5 convenbottor' ,a layer of crushed granite 16 er iently of wood, and an inner layer 6, of sheet analog` i material upon said felt layer 15, metal. Between these two

layers

5 and 6 is aneth felt layer 17 upon said crushed 95 a filling 7 of bibulous material, that is at the granil Lyer, and a perforated plate 18 upon same time a poor conductor of heat. The said f layer 17. The grate 19 for the ice inner layer 6 is punctured at intervals as is sup ted above said perforated plate 18. shown at 8 so that the bibulous material 7 The i an is provided with handles 20 by can absorb the moisture in the refrigerator mean: which it can be lifted from the ieebox. A series of perforations 9 are made in chest, cleansing or otherwise. It will of 5o the outer wall of the refrigerator whereby the cours a understood that filters of other conchamber between the outer and inner walls struct could be employed but the concan communicate with the outside air, and I struct shown is found preferable.

I claim as my invention- 1. A refrigerator having outer and inner Walls, an interposed layer of bibulous material, openings or perforations in the inner side walls, and openings or perforations in the outer wall, whereby moisture absorbed by said bibulous layer through openings or perforations in the inner side walls can evaporate through said openings or perforations in the outer Wall, substantially as described.

2. A refrigerator having outer and inner Walls, an interposed layer of -bibulous material, openings or perforations in the upper portion only of the inner side walls, 'and openings or perforations in the outer Wall, whereby moisture absorbed by said bibulous layer through openings or perforations in the inner side Walls can evaporate through said l openings or perforations Vi-n the outer wall,

substantially as described.

3. A refrigerator having outer and innerf walls, an interposed layer of bibulous mate-l rial, openings or perforations in the inner side walls, and openings or perforations in the outer top wall, whereby moisture ab sorbed by said bibulous layer through openings or perforations in the inner side walls can evaporate through said openings or perforations in the outer Wall, substantially as described.

et. A refrigerator having outer and inner walls, an interposed layer of plaster of paris,

openings or perforations in the inner side walls, and openings or perforations in the outer wall, whereby moisture absorbed by said layer of plaster of paris through the openings in the inner side walls can evap0- rate through said openings or perforations in 'the outer wall, substantially as described.

5. A refrigerator having an ice-chest, an
