Application',ledl. May 27, 1922. Serial No. 564,153.

To all whom it may concern Be it known that we, JULIAN WEST and EDWARD C. CAMPBELL, citizens of the United.

States, residing at Norfolk, in the county of Norfolk and State of Virginia, have invented certain new and useful Improvementsl in Refrigerators, of which the following is' a specification.

This invention relates to refrigerators, and vhas for one of its objects to simplify and impro-ve the construction of devices of this character and produce a refrigerator of increased efficiency and utility.

Another object of the` invention is to provide a device'of this character having improved means for causing the air to circulate around the ice and through the food receptacles, whereby the benefit derived from the cooling properties of' the refrigerating agents is materially increased and used with increased economy.

in the ice chamber.

`With these and other objects in View the invention consists in certain novel features of construction as hereinafter shown and described and' then specifically pointed out in the claim, and in the drawings illustrative of the preferred embodiment of the invention Figure 1 is a perspective View of the improved refrigerator.

F ig. 2 is a vertical sectional side elevation with the ice and food chamber doors `open, and the food containing drawers partly withdrawn.

Fig. 3 is a transverse section.

Fig. 1 is a bottom plan view of the air escape device of the ice chamber. v

F ig. 5 is a detail view, enlarged, of the discharge of the air escape.

1F ig. 6 is an'enlargedisectional detail illustrating the construction of the joints between the swinging closures of the ice and food chambers. L

The improved refrigerator includes an 'outer shell or casing of wood or metal, and preferably of a plurality of horizontal sections 10 united by Z shaped joints 11. as shown in Figs. 1, 2, 3 and V6, and with a relatively long doorway opening 12 in one wall at the upper part of the shell and relaltively short door way opening, one of which is sllliown at 13, in the lower side of the same wa v The side, rear, and front walls of the shell 10 are lined with a plurality of layers of heat and cold resisting material comprising a layer of asbestos material, indicated at 14C next to the inner faces of the strips or sections 10, a layer of pressed paper material such as the product commonly known as beaver board or the like, and indicated at 15, and an innerlining of noncorrosive metal such as galvanized iron or steel, porcelain coated metal, or the like, and indicated at 16.

The shell is also provided with a floor Aof suitable material formed in two sections 1T and 18 in spaced relation to provide a dead air space 19,` between them and thus forming a nonconductive bottom tothe shell.

Extending transversely of the interior of the shell just below the line of the doorway 12, is a horizontal partition 20, forming a chamber for the i'ce, indicated at 21, and accessible through the opening.

,The ice chamber isl divided by a vertical partition 22 to provide a smaller compartment at one end for thereception of articles of food which require a lower temperature than is possible to be attained in the ordinary food chamber.

Formed through the shell between the openings 12and 13 are other openings to closure 25 hingedly connected to the bodies of the drawers as shown at 26.

Two of the drawers are shown for illustration but any required number may be employed. j Y Each drawer is supported by an outer guide rib 27, and an inner guide rib 28, the latter in spaced relation to-'permit air to freely circulate between the drawers.

The space between the drawers 23 and the bottom of the shell constitutes the food chamber, and is divided into two portions 30 to swing downwardly, and limited in its iro movement by a chain 33, while the openings 13 are provided respectively with doors 34 hingedly connected at 35 to the shell to swing downwardly, and limited in their movement by chains, one of which is shown at 36.

Each of the doorway openings is surrounded by a ii-shaped rib 37, and the inner face of each door is lined with three layers of the asbestos 14, beaver board 15, and the noncorrosive lining 16, the same as the interior of the shell, and the lining member 16 is extended around the'edges of the bodies of the doors and bent to conform to and closely engage the ll-shaped ribs of the doorway openings, as illustrated at 38 in Fig. 6.

-By this means air tight joints are provided between the doors and the shell when the doors are closed.

A corrugated ice supporting plate 39 is provided for the ice chamber, to hold the ice block spacedffrom the partition 20.

Supported by clips 40 upon the inner Jface of the top of the shell is an air outlet conductor represented as a whole at 41, and eX- tending at one end through the rear wall of the shell and terminating in a funnel shaped enlargement 42, the' latter preferably provided with a screened cap 43 to prevent the entrance of dust, insects or the like into the conductor. l

At its inner end the conductor 40 is formed with a downwardly directed opening. 44, and also preferably directed laterally as shown at 45 to increase the length and thus retard the passage of the air therethrough.

'lower part toward the center of the shell and Branching from ythe conductor 41 is a vertical conductor member 46 directed at its :reliance turned down at its inner end through the partition `20 as shown at 47.

By this means the ice chamber and the food chamber will be eectually ventilated and the air escaping from the food chamber will not come i1- contact with the ice in the ice chamber.

A drain pipe 48 leads from the ice chamber, as shown in Fig. 2.

rlhe improved device is simple in construction, can be manufactured of any required size or capacity.

The preferred embodiment of the invention is disclosed in the drawings and set forth in the specifications, but it will be understood that modifications within the scope of the claimed invention may be made in the construction. without departing from the principle of the invention or sacrificing any of its advantages.

Having thus described the invention what is claimed as new is Y `A refrigerator comprising an enclosing shell, a transverse partition defining an ice chamber and a food chamber, a plurality of drawer devices movable through one wall of the shell between the ice chamber and the food. chamber with their confronting sides in spaced relation to provide means for the circulation of air, a main escape conductor leading from the ice chamber, and a branch air conductor leading from the food chamber between the drawer devices and connected into the-main air conductor.

ln testimony whereof, we aix our signatures hereto.

JULIAN WEST. EDWARD CAMPBELL.
