Application led November 20, V1926. Serial No. 149,746.

This invention relates to refrigerating apparatus, particularly to walls or closures for refrigerating cabinets, and is especially applicable to cabinets for keeping ice-cream in restaurants, soda fountains and the like.

An object of the invention is to provide means for maintaining articles cooled by a refrigerating cabinet at a 'higher temperature than that normally prevailing in the cabinet.

Another object is to provide improved means for keeping articles cold, yet readily accessible.

Another object-is to provide an improved wall, or a closure for refrigerating cabinets adapted to receive articles to be cooled.

Further obiects` and advantages will be apparent from the specification and drawings, in which Fig. 1 shows the invention applied to an ice-cream cabinet, and

Fig. 2`is a section on the line 2-2 of F ig. 1.

It is known that a temperature much below the freezing point of water is required to keep ice cream satisfactorily. Bottled goods, such as syrups and beverages, should be cooled, but should be maintained at a temperature appreciably above freezing in order either not to freeze solid or congeal to an undesired consistency. My invention provides a simple and inexpensive means for keeping both these commodities at the required temperatures in an ordinary icecream cabinet.

Referring to the drawings, 10 represents a conventional ice-cream cabinet having insulating walls 11 and sleeves 12 for the reception of cylindrical ice-cream cans 13. Brine, or other refrigerating medium, is circulated in the space between the sleeves. As is usual, the cabinet has a thick insulating top 14, which extends a considerable distance above the tops of the cans. Thick insulating covers 15 are usually provided to close the openings over the cans. The present invention contemplates a cover 16 having the usual thick insulating portion 17 and metal linings or facings 18. One or more holes 2() are formed through the cover and these are closed by suitable thin, thermal conductingmembers 21, which permit a certain amount of heat to be absorbed through the cover by the refrigerating. apparatus within. These closure members may consist of any. suitable material, or be of any suitable vshape or thickness, the choice being dependent upon the nature ,of the articles to be cooled and the degree of cooling required. As shown in the drawings, I may construct them ot' metal cups, which are secured to the metal linings 18 and project into the interior of the cabinet. TheA distance these cups project into the cabinet influences the amount. of heat which can be absorbed through them and, consequently, the degree of cooling applied to the articles stored therein. In the case lof syrup bottles 23, it is desirable to have the bottom of the cups just above the surface of the ice cream when the cans are full. The bottles project a considerable distance above the top of the cabi.,` net and thus absorb heat from the outside atmosphere and prevent the contents from freezing solid or congealing to an undesired consistency, as would otherwise take place if the bottles were merely placed' in the cabinet.

It is understood that the invention is not limited to the particular details whichhave been selected for illustration, but covers modifications which coine within the scope of the appended claims.

What is claimed is as follows:

1. A refrigerating apparatus having a refrigerating tank, a food compartment in said tank and an opening in the top wall of said apparatus for the insertion or removal of food in the compartment, a closure lfor said opening, and a heat conducting cell in said closure, being normally open at the top and having thermal contact with said compartment for the reception of a container of a substance to be cooled.

2. An ice cream cabinet having a sleeve in a refrigerating compartment for the reception of anice cream can, a lid over said sleeve, and a heat conducting cell in said lid in thermal contact with said compartment open at the top and a bottle partially in said cell adapted to contain a substance to be cooled to a temperature higher than the temperature in said compartment.

3. An ice cream cabinet having sleeves in a refrigerating compartment for the reception of ice cream cans, lids over said sleeves, and a heatl conducting cell in at least one of said lids in thermall contact with the sleeve thereunder, and a bottle partially in and eX- tending upwardly from said cell and adapted to contain a substance to be cooled to a temperature higher than the temperature of said compartment.

4. A refrigerating apparatus having a food compartment therein and an opening in a Wall of said apparatus for the insertion or removal of food in the compartment, a closure for said opening, and a heat con ducting cell in said closure permanently open externally of said cabinet and having thermal contact With said compartment for the reception of a bottle or the like adapted to contain a substance to be cooled.

5. An ice cream cabinet having a sleeve in a refrigerating compartment for the reception of an ice cream can, a lid over said sleeve, and a heat conducting cell in said lid permanently open externally of said cabinet in thermal contact with said compartment for the reception of a bottle or the like adapted to contain alsubstance to be cooled.

In testimony whereof I hereto aix my signature.
