TWO-TEMPERATURE REFRIGERATING AND COOLING CABINET.

Application filed August 5, 1925. Serial No. 48,377.

One of the objects of this invention, consists in anew, novel, and useful improvement in a two compartment cabinet, wherein articles of merchandise may Abe maintained in each compartment and each adapted to having a different temperature main- 'tained therein.

A further object of my invention consists,

in a hinged closure wherein access may be had to eac-h compartment from either side of the cabinet.

A further object of my invention consists in a thin cooling medium tank being disposed about the vertical side and end walls of each compartment, adapted to the maintaining of the cooling medium therein and the passage therethrough of' an expansion coil for maintaining low temperatures in each compartment, the temperatures in one of the compartments to be maintained at a lower temperature than in the other.

Still further objects of my invention, consist in the construction of a cabinet that may be produced in quantity production in a central plant and shipped to the'point of use, wherein all parts are interchangeable and a minimum of space may be occupied by the cabinet with a maximum of storage capacity in each of the compartments to be refrigerated.

A further object of my invention consists in the construction and anrangement of the cooling medium tanks within the compartments for the maintaining of the cooling medium therein` the tanks to form the vertical side and end walls of the compartments to be refrigerated.

Still further objects of my invention, conthe vertical side Walls of the compartment only,'with no. cooling medium being disposed below the surface of the bottom of the compartment to be refrigerated.

Still further objects of my invention, consist in the detailed construction of the cabinet, wherein a refrigerated two compartment cabinet is constructed having its outer surfaces made out of suitable material as plywood or veneer, and having a top closure through which admission may be had intov each compartment from either side of the cabinet.

With these and incidental objects in view,`

sists in the cooling medium being adjacent forth in the appended claims and to a preferred form of embodiment of which is hereinafter shown with reference to the drawing which accompany and form a part of this specification.

l is the cabin-et. I first form a frame structure composed of posts 29, to which are secured side and end rails 30, the same being framed together and secured by suitable fastenings, as screws and glue, orby any other suitable fastening means after which an outer ply wood or veneer covering is placed, the same being finished in any suitable manner to resist the character of usage for which the cabinet is to be used as by shellac or any high grade moisture resisting varnish. A high temperature compartment 2, and a low temperature compartment 3, are disposed within the cabinet, access into each of which may be had though an insulated lid closure disposed and fitted susk to the entrance tothe compartments through the top of the cabinet; surroundmg each compartment is a cooling medium tank adapted to the circulation of a coolinvr medium therein. The tank 4, in the high temperature compartment does not extend the full depth of the compartment and finishes on its inner side walls in a vertical straight line, as shown at 5, the refrigerant material passing around the upper portion of the compartment. The tank 6 in the low temperature compartment, extends for practically the full distance of the inner, `vertical walls and entirely surrounds the vertical side and end Walls of the compartment, as shown at 7 the outer Walls of the cooling medium tank 6, finish in a straight line for the entire depth of the compartment. The bottom of each compartment, as shown at 8, does not have a refrigerant circulated thereunder.

In the construction of my cabinets, I rst lay a full layer of insulating material, as 9, entirely across the bottom 10, of the cabinet. I then place the side Walls 11, of the insulating material, after which I lay a second layer 12, entirely across the bottom, after which I place a second layer 13, of the side walls. The end wall layers are then placed, as shown at 14, the same being placed at either end of the compartment and across the central section dividing the cabinet into twoseparate and distinct compartments. The metallic pans 8, are then placed in each compartment. The cooling medium tanks are then placed therein, after which the top insulating material is placed. The top of the cabinet 15 may then be placed, and secured in position by any suitable fastening means, as screws, or if it is desirable to place the expansion coilswithin the cooling lnedium tanks first, the same may be done these expansion coils are not shown herein, as the same may be placed after temperature compartment.

the delivery of the two temperature cabinet to the user, or the distributor of the same. It will be noted that in the, high tempera- Iture compartment, that the cooling medium tank is disposed -about the upper portion of the tank; in my construction I forni these cooling medium tanks in depth slightly more than the outer diameter of the expansion coil, thus reducing the amount of cooling medium to a minimum to be used. A third layer of insulating material 16, is placed below the cooling medium tank in the high Cross bars 17', are placed on the larger compartmentfor hinging the closures 18 and 19, therein; handles 20 and 2l being provided to facilitate the raising and lowering of the closures. Hinge members 22, are provided upon the closure, and which are secured to the closure, by suitable fastening means, as screws. These hinges have projecting lugs 23, adapted to engagement with the cross members 17y in slots 24, provided for that purpose In the smaller compartments, a double closure 25, is split transversely its length and hinged at its meeting edges, as shown at 26, a handle member 27, being provided to facilitate the movement, and the raising of the same. This split hinged member is not secured to the cabinet and may be lifted olf entirely when desired for the admission of heavy articles to be placed therein, as ice cream cans. Legs 28, are disposed upon the lower portion of the cabinet to prevent the same sitting flatly upon the supports, as the floor, where the same is to be used, as a lcertain amount of moisture is present at all times. These legs permit of an air circulation beneath and around the cabinet. A frame structure of posts 29, and side and end rails 30, is provided for strengthening the cabinet. The outer covering of the same being preferably formed of ply wood, or laminated material, which is properly treated on the outside to prevent warping and becoming saturated with the liquids being used thereabout or therearound. The posts, side and end rails are mortised, as shown in detail in Fig.'9, to form a strong and uniform frame structure, sufficiently strong to maintain the weight of the cabinet.

While the form of mechanism herein shown and described is admirably adapted to fulfill the objects primarily stated, it is to be understood that it is not intended to confine the invention to the one form of embodiment herein shown and described, as it is susceptible of embodiment in lvarious forms, all coming within the scope of the claims which follow.
