Specification of Letters Patent.

Patented Nov. 7, 1911.

Application filed June 23, 1910. Serial No. 568,562.

To all urhmnv't may concern: Be it known that I, VALTER R. J ENNISON, a citizen of the United States, residing at Atlanta, in 'he county of Fulton and State of Georgia, have invented certain new and useful Improvements in Refrigerators; and I do hereby declare the following to bea full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements 1n refrigerators, and has for an object 1mproved means for maintaining the Water from the melting ice in the refrigerator until substantially all cooling effect thereof chamber and what 1s known as an ice chamhas been removed.

Another object of the invention is the arrangement in a refrigerator of means for creating a circulation of air within the refrigerator but not in contact with the interior of the produce chamber.

A still further object of the invention is the arrangement of a double walled refrigerator in which the walls are spaced apart, having apertures at'the upper end thereof, .whereby a free circulation of air may be had between the walls, and a plurality of pipes arranged between said walls for holding the water from the melting ice until the same has been deprived of substantially all of its cooling effect. I

A further object of the invention is the arrangement of a refrigerator divided along the lower edge of the ice box or chamber,

and arranged to be bodily moved so that the upper section or ice box may be turned so that the door therein may be at the front of the refrigerator or back as desired without interfering with the circulation of air and other cooling medium.

With these and other objects in view the invention comprises certain novel constructions, combinations, and arrangement of parts as will be hereinafter'more fully described and claimed.

In the accompanying drawings: Figure 1 is a perspective view of one embodiment of the invention, certain parts being in section approximately on line 1-1 of Fig. 3. Fig. 2 is a' section through Fig. l on line 22, the same being shown slightly separated for better illustrating the structure. Fig. 3 is a top plan view partly in section of the bottom section shown in Fig. 2. Fig. 4 is a longitudinal vertical section through a refrigerator embodying a slightly modified form of the invention. Fig. 5 is a detail fragmentary perspective view showing the arrangement of the water carrying tube. Fig. 6 is'a section through Fig. 4 approxim'ately on line 6-6. Fig. 7 is a section through Fig. 6 on line 7-7.

In forming a refrigerator embodying the invention any desired material may be used, as for instance wood, glass, porcelain, clay, iron either cast or of the wrought variety, or a combination of these and other materials may be used as desired.

The refrigerator is divided into a produce her, the ice chamber being entirely separated from the produce chamber so that there 'is 'no passage of air between the two chambers.

Surrounding and forming the ice chamber and produce chamber are spaced walls which form therebetween an air-passage way for permitting a free circulation of air through the opening into the ice chamber entirely around the produce chamber. This circulation of air is around the produce chamber but does not enter therein. In order to assist this circulation of air in cooling the produce chamber the drainage from the ice chamber is held in a plurality of pipes or passage-ways between the walls of the refrigerator for a considerable time before the same is permitted to pass out entirely from the refrigerator, whereby the cooling effect of the low temperature drainage will be used for assisting in cooling the produce chamber.

Referring to Figs. 4 to 7 lncluslve, 1 1ndicates the outer wall or housing, and 2 the inner wall or housing. The outer and inner walls when made of cast iron are joined at the corners, as shown in Fig. 3. The corners have arranged therein passageways 3 which receive the drainage through openings or apertures 4. The drainage passes down through passage-ways 3, through horizontal pipes 5 and 6, and again upward through vertical pipes 7 and 8. The pipes 7 and 8, and also pipe 9, are connected with a coupling member 10 slightly below the openings 4, so that the drainage will freely pass out through openings 4 but'will be maintained at a height almost level with the bottom of openings 4. When the drainage from ice chamber 11 has raised the water in pipes 7 and 8 up to member 10, any surplus water drained from chamber 11 through openings 4 will cause an equal amount of Water to pass out theupper ends of pipes 7 and 8, and into pipe 9, from which it passes through a suitable drain pipe 12 to any desired place of disposal.

The inner wall 2 of ice chamber 11 is provided with a plurality of apertures 13 which permit the passage of air from the ice chamber into the sides of the refrigerator, and thenback into the ice chamber. No opening is provided in the rear of the ice chamber so that the circulation of air is from the sides of the ice chamber to the sides, back and front of the produce chamber for maintaining the produce chamber in a cooled condition. The doors 15 and 16 of the refrigerator may be made of any desired or usual construction.

In the drawings is disclosed a cast or molded refrigerator, but if a refrigerator were made of wood or other material the passage-ways 3 would be provided by the extension of vertical pipes at the corners until the same open into the apertures or openings 4- In casting the refrigerator the same, of course, may be cast either at one time or in parts as desired, as for instance,

produce chamber 14: may be eliminated from the first casting and cast independently, after which may be placed in position.

In Figs. 1, 2 and 3 an embodiment of the invention is shown, in which the refrigerator is made into two or more sections. In this form of the invention the ice chamber 17 is formed with side walls and a top. The bottom 19 of said chamber may be made a part of either section or made a separate partition plate. The bottom edge of the side walls is formed with a notched out portion 18 which fitsover the notched portion 19 in the lower part of the refrigerator. This will produce a tight joint and will readily permit the water to escape through openings 4 into the front passage-ways 3 from which it passes through pipes 20 and 21 to the bottom of the rear passage-ways 3. Pipes 22 and 23 are connected with the rear passage-ways 3 near the upper end thereof so that when the water rises in the rear passageway 3 to a height slightly below openings 4 the same will pass into pipes 22 and 23 and from thence pass-to fitting 24 and down discharge. pipe 9, from which it may pass to any desired place. By this structure the refrigerator is cast in two or more parts and the apertures in the corners thereof provided for the circulation of the cooling water from the ice chamber in such a manner that the cooling water'is maintained for a maximum time inthe refrigerator whereby the maximum cooling effect is produced. This efl'ecclusive, and embodies the same principle of circulation of air and circulation of water for maintaining the produce chamber cool, and utilizingto the fullest extent the cooling effect of the ice and meltage.

Other changes in the casing may be provided without departing from the spirit of the invention in the use of the drainage water from the ice chamber and the particular circulation of air around the produce chamber between the spaced walls of the refrigerator.

By the arrangement of the double walls as set forth the chilled air from the ice chamber may circulate freely around the produce chamber but not within the same so that the ice chamber is not contaminated with any of the contents of the produce chamber. and yet the produce chamber is cooled effectually. lation of the cooled or chilled air around the produce chamber, the additional cooling influence of'the melted ice or drippings from the ice chamber is utilized.

The arrangement of the pipes or passageways around the produce chamber but not in communication therewith, presents means which causes the utilization of the cooling effect of both the circulation of chilled air and the circulation of chilled water, in proximity to the produce chamber. From the structure set forth, therefore, it will be observed that a maximum amount of cooling effect is obtained by the use of drip or drainage, the circulation of chilled or cooled air and the holding of the cooled water result.- ing from the melting ice in proximity to the produce chamber until the chilling effect of the water has been substantially fully uti lized.
