Application filed February 20, 1918. Serial No. 218,264.

of New Mexico, have'inv nted certain new and usefullmprovements 1n Refrigerators,

. of which'the following is a specification.

This invention relates to improvements 1n refrlgerators.

In carrying outthe inventlon an outer casing or housing is provided andequipped with means for creating and circulating, artificially a current of air. Within the housing sheets of fabric are disposed so as to surround supports on which the articles to be cooled may be placed. Means for saturating the sheets is provided and the current of air passes around and through said sheets causing an evaporation whereby a low temperature is obtained. It is also proposed to provide a door for the housing giving access to the interior and to include a novel arrangement for supplying moisture to a sheet of abric carried by the door and whereby the cooling chamber is entirely surrounded by sheets of fabric. One of the features of the invention is the inclusionof a water cooling tank for providing drink ing water.

The invention will be more readily understood from a reading of the following specification and by reference to the accompanying drawings, in which an example of the invention is illustrated, and wherein Figure 1 is a side elevation of a structure built in accordance withthis invention and illustrating a portion of one side as broken away to show the sheet of fabric within,

Fig. 2 is a vertical sectional view, and

Fig. 3 a horizontal cross sectional view,

the view being taken on the line 33.

In the drawings the numeral 1 designates an upright housing or casing rectangular in cross section and having a door 2 in one side which we will term the front. The upper end of the housing is closed by a cap or lid 3 fitting tightly thereon but being moved by means of a handle 4. Within the housing a vertical rack 5 rectangular in cross section is mounted. This rack includes four corner posts and its transverse area is somewhat less than the transverse area of the inside of the housing so that when the rack is placed concentrically within the same 'a space on each of the four sides is provided the'rebetween. The rack supports at its top' residing at aremovable pan 6 which overhangs the sides of the rack as shown in Fig. 2. From three. ofthe sidesof the pan fabric sheets 7 depend, but have their upper ends immersed in water in said pan whereby said sheets are On the inner-face of the door I mount a sheet of fabric 10 and provide a short length of fabric or feeder strip 11 which de ends from the pan and has its lower end to terminate just below the top of the door so as to overlap the sheet 10. A transverse bar 12 mounted on the rack is positioned so as to bind the feeder strip and the sheet 10 together when the door is closed, thus supplying moisture to said sheet. This transverse'pressure bar extends the width of the door and gently presses thefeeder cloth against the door cloth when the door is closed. r

K In therear wall of the housing an air inl et duct or'flue 13 is arranged and within this flue a' suitable motor driven fan 14; is mounted. This motor may be operated in any suitable manner and the fan is'arranged so as to draw air into the duct and create a current which passes through the sheets 7 and also up the space surrounding the same to an outlet 15 in the cap 3 whereby a cir-. culation is obtained. Experience has shown that only a moderate current is required and that the fan may be run .quite slowly. The circulating air coming in contact with the moistened sheets sets up an evaporation whereby the temperature within the housing is reduced" and maintained, at a degree considerably lower than the degree of temperature outside of the said housing.

One or more shelves 16 may be included in the rack 5' and a flat water tank 17 is removably mounted in the rack so thatit may be taken out and cleaned when desired.

This tank is provided with a faucet 18 wherebycooled water may be drawn oil for drinking purposes. It will be seen that by 5 removing the cap 3 the rack and the sheets of fabric may be removed from' the housing and the same cleansed. The fabric sheets are protected from dust and dirt and a high sanitary condition maintained.

The foregoing description and illustration clearly express the invention, but it is to be understood that said illustration is merely an exemplification and the invention may be system supplied, a supporting rack for shelv'esand pans provided in the casing and removable therefrom, cooling sheets of fabric depending from the sides and the rear of low the upper edge of the door,

the casing and spaced apart from the walls of said casing to facilitate air circulation, feeder cloths attached to the cooling sheets of fabric "and lying within a pan of water to transmit moisture, a cooling sheet fixed on the door, a feeder strip of fabric lying within the water pan and depending slightly bea pressure bar fixed within the casin and positioned to support the lower edge 0 the feeder strip causlng, said strip to engage the cooling sheet on the door thus transmitting moisture to the'said door sheet in a positlve manner.

In testimony whereof I aifix my signature.

CHARLES T. ADAIR.
