UNITED STATES HENRY ADELMAN, OF FLORENCE, ALABAMA.

REFRIGERATOR.

Application filed March 6,1924. Serial No. 697,297.

To all whom it may concern Be it known that I, HENRY ADELMAN, a

citizen of the United States, residing at ice for the refrigerator, as well as preventing any warm air from entering through the walls of the ice box or refrigerator.

Another important object of the invention is to provide a refrigerator of the above mentioned character, wherein the same is provided with cold air spaces between the inner and outer walls thereof, and beaver boards are arranged on the inner opposed faces of the spaced walls, so as to insure the refrigerator against the passage of heat through the walls thereof.

A further object of the invention is to provide a refrigerator of the above mentioned character, which is simple in construction, inexpensive, strong and durable, and further well adapted for the purposes for which it is designated.

Other objects and advantages of this ini'ention will become apparent during the course of the following description.

In the accompanying drawing, forming a part of this specification, and in which like reference characters designate like parts throughout the same:

Figure 1 is a central o-f my invention and Figure 2 is a vertical section there through.

In the drawing, wherein for the purpose of illustration is shown the preferred embodiment of my invention, the numeral 1 designates the casing of my improved refrigerator and comprises the spaced outer and inner walls 2 and 3 respectively. All of the walls of the casing are arranged in spaced relation, in the manner as clearly shown in the drawing, and whereby a cold air space 4 is formed between the spaced inner and outer walls. The walls of the ice boxer refrigerator may be formed of any su table material, preferably wood.

longitudinal section,

Arranged on the inner opposed faces of each of the walls, are the layers of beaver board 5 and 6, and 7 and 8 respectively. A pro-- vision of a double layer of beaver board, on the inner face of each of the walls, provides a means of insuring against the passage of any warm air from theoexterior of the refrigerator through the walls of thecasing.

The layers of beaver board, when in position, will not interfere with the cold air space 4 formed between the wall. Suitable spacing strips, such as are shown at 9 in the drawings, are adapted to be disposed in the air spaces formed around the sides of the casing, with the top and bottom thereof between the interposed layers of beaver board so as to maintain the interposed beaver boards in proper spaced relation, thereby enabling an equal air space to be provided entirely around "the walls of the casing on all sides thereof, including the top and bottom.

Extending vertically in the casing 1, adjacent one side thereof is the partition 10, which is provided with a series of openings or apertures 11. This construction forms an ice compartment 12, and an enlarged food compartment 13. Suitable transversely extending rods 14 are adapted'to be arranged in the food compartment 13 for supporting the trays 15 in the usual manner, in proper spaced relation, as is well known in the art, and it is not thought necessary to further go into detail relative to the same. The compartment 12 is provided in its top, with an opening for the reception of ice therein, and cooperating with the opening and in the top of the ice compartment is the door 16. The door 16 is of the. well known hinged type, and in the present instance, the door is constructed in the same manner as the walls of the casing, wherein the same comprises the outer wall 17 and the inner wall 18, and adapted to be arranged on the inner faces thereof are the beaver boards 19 and 20 respectively, form ing an air space 21 therebetween, in a manner similar to'the air space 4, the construction of which was heretofore described. A similar door 22 is provided for the open ing 23 formed in the front of the compartment 13, and this door 22 is also provided with the outer wall 24: and the inner wall 25, the inner faces of which are arranged with the beaver board 26 and 27 thereon, and air space 28 is formed therebetween.

clude the possibility poses well known in the art. The bottom of the ice compartment 12 is providedwith the drain pipe 30, which extends through the bottom of the casing, and in communication with the liquid fuel trap 31 of the conventional construction, vso as to take care of the overflow of water from the ice compartment therein, in the usual manner. The refrigerator is rendered portable by providing the rollers 32 at each of the corners thereof, and the bottom.

It will thus be seen from the foregoing description, that by providing'a refrigerator of the above mentioned character, wherein the same is provided with a cold airspace between the inner and outer walls of the casing, the ice within the compartment 12 will last for a considerable length of time, thus lessening tli e cost of keeping the ice box or refrigerator in a'cold state,

walls and beaver boards are associated therewith.

A refrigerator of the above "mentioned",

A refrigerator of the above mentioned character may be manufactured at -a very low cost.

While I have shown the preferred embodiment of my invention, it is to be understood that various changes in the size, shape and arrangement of parts may be resorted to,

without departing from the spirit of the in vention, and the scope of the appended claim.

Having thus described my what I claim as new is: p

A refrigerator of the class described, comprising a casing infcluding outer and inner spaced walls forming an air space thereinvention,

between, layers of beaver board arranged on the inner opposed faces of the said walls, means extending in said air spaces for retaining the walls and beaver board carried thereby in-spaced relation, a partition in said casing forming compartments therein and having openings therefor, doors for said openings,said oors having inner and outer spaced walls forming an air space and prolonging the consumption of the ice. therebetween, and beaver boards arranged on Furthermore, there will be no tendency of any warm air to come in contact with the interior of the refrigerator, due to the fact that an air space is "formed between the the inner opposed faces of the spaced walls of said doors. f

In testimony'whereof I aflix my signature. t I HENRY ADELMAN.
