signor to Bruno-New York, Inc., New York,-

N. Y., a corporation of New York I Original No. 1,927,398, dated September 19, 1933,

Serial'.No. 650,675, January 7, I933.

Application for reissue December 11, 1934, Serial No .My invention relates to a newand improved refrigerator.

One of the objects of my invention is to provide a new and improved refrigerator of the iceless type, in which the refrigeration is supplied by any suitable mechanical or chemical unit... My invention applies particularly to the well-knownelectrical refrigerator, refrigerators oi. the Electro-Lux" type, etc. Oneof the objects of my invention is to provide a refrigerator of this type with. a special compartment at the open end thereof.

Another object of my invention is to provide a compartment of this type whichis mounted upon a suitable hinge and which is at or adjacent the inner face of the door of the refrigeratorh Another object of my invention is to provide a compartment of this type which is constructed so as to produce a temperature therein which io may be the same or which may be higher than the temperature within the main part of the refrigerator.

Other objects of my invention will be set forth in the'following description and drawing which illustrates a preferred embodiment thereof, it being understood that the above general statement of the objects of my invention is intended inere ly to generally explain the same and not to limit it in any manner.

I Fig. 1 is a perspective view illustrating one embodiment of my invention.

Fig. 2 is a sectional view on the line 2-2 of Fig. 1. r v Fig. 3 is a detail sectional view showing a dif ferenttype of shelf having a lip or flange at its front end.

Fig. 4 is a. horizontal sectional view of the device shown in Fig. 1.

Fig: 5 is a view similar to Fig. 4 showing a diiferent embodiment. p The refrigerator It may be of any suitable type," and it is provided with a door I which is mounted upon a hinge 2. Said. door and hinge may be oi any suitable type. Thedoor I is held in the closed position by means of a latch3 of any suitable type. As shown in Fig. 1, the refrigerator has a main compartment, having cooling means in the upper part thereof. In the embodiment illustrated in Figs; 1 and 4, the compartment 4 is made oi any, suitable metal i and said-compartment has its rear wall provided with one or more openings or louvres 5 of any suitable type, so thatthere is, a. circulation of 56 refrigerated air between thev interior of the .com-

ing of the refrigerator.

5 Claims. 101. 62-89) partment 4, and themain body or compartment of the refrigerator.

The compartment 4 is provided with shelves 6 of any suitable construction. The rear wall of --the'compartment may be provided with angle 5 irons 1 upon which the rear ends of the shelves 6 may be located. Said shelves 6 may have flanges 8 which are welded or otherwise suitably secured to the side walls of the compartment. Said shelves may have openings 50., which may vary in number, in order to facilitate the circulation of air through compartment I. Said shelves may be connected adjustably to the side walls of compartment 4.

In the construction shown in Fig. 3 the shelves 6 have lips or flanges to at their front ends.

The compartment is likewise provided with front rails 9 which are suitably connected to the side walls of said compartment.

This construction makes "it possible to locate glasses, bottles, and the like upon the shelves of the compartment. For example, the compartment can be used for holding containers of beverages, sauces, and the like, which become too cold when they are placed within the main body of the refrigerator. This excessive chilling is often undesirable, especially in mayonnaise, dressings and the like. r

In the embodiment shown in Fig. 4, the com-'- partment 4 is connected bymean's of a hinge III to the' inner face of the door-L There may. be enough friction in the hinge l0 so that the door I and the compartment 1 will open in unison.

vIn the embodiment shown in Fig. 5, the compartment 4 is connected by means of a hinge Illa to one of the side wallsbf the refrigerator; "Like- .wise, in this embodiment, the compartment has a tapered shape so that it fits closely in the open- The compartment may be made of any suitable material such as steel which may have the thicknessof 18 to 20 gauge.

Experience has shown that since the'compartment has a relatively solid rear wall, provided .with relatively small openings 5, the temperature within the compartment'is several degrees than in the main body of the refrigerator. How,- ever, I do not wish to be restricted to any particular size or number of the openings 5. I prefer-that said openings 5 should not occupy more oftlie rear wall of the compartment l. I Generally speaking, my invention applies to all than about twenty-five percent of the total area temperature of the refrigerator is maintained as low as 20 F. I

In an ordinary domestic refrigerator, the lowest'temperature which is maintained is about 40 F. Certain foods, such as oily salad dressings, should be kept at a temperature which is not below about 50 F. Likewise, foods which contain a large percentage of water, such as plums or peaches, should not be chilled to 40 F., as they become inedible. By having the areas of the openings 5- suillciently small, it is possible to maintain a temperature of about 50 .F. in the compartment 4, although the interior of the refrigerator is maintained at a normar minimum temperature of 40 F. If the area of openings 5 is about (twenty flve percent) of the total area of the rear wall of compartment 4, there is little or no difference in temperature between compartment 4 and the interior of the refrigerator. While exact figures cannot be given for every style of refrigerator, because of variation in freezing capacity, etc., if the area of openings i is about ten per cent of the total area of the rear wall of compartment 4, it is possible to keep the compartment 4 can be made of porcelaincovered steel, so that the wall of said compartment provides sufllcient insulation, so as to make it possible to keep compartment 4 at a. higher temperature than the interior of the refrigerator.

The relatively higher normal temperature of.

ings I, at the top and bottom of the rear wall of compartment 4, in order to provide circulation ofair between the compartment 4 and the interior of the refrigerator.

If desired,the wall of the compartment 4 may consist either wholly or in part of any suitable insulating material so as to maintain a diil'erence' of temperature between the interior of said compartment and the interior of the refrigerator.

I have shown a preferred embodiment of my invention, but it is clear that numerous changes and omissions can be made without departing from its spirit.

1. An iceless refrigerator having a main compartment which isprovided with an outer door,

said main compartment having cooling means in mounted by a hinge which is located adjacent the inner surface of said outer door, and means located so as to provide a circulation of refrigerated air between said box-like member and said main compartment.

2. An iceless refrigerator having a maincompartment which is providedwith an outer door,

' and a box-like member having a back which is surrounded by a peripheral flange, said box-like member being turnably mounted by a hinge which is located adjacent the inner surface of said outer ddor, said box-like'member having superposed openings so that there is a circulation of refrigerated air between said main compartment and the interior of said box-like member.

3. An iceless refrigerator having a main compartment which is provided with an outer door, and a box-like member having a back which is surrounded by a peripheral flange, said box-like member being turnably mounted by a hinge which is located adjacent the inner surface of said outer door, said box-like member being provided with superposed openings so that there is a circulation of refrigerated air between said main compartment and the interiorof said box-like member, said box-like member having perforated shelves which permit the circulation of the air.

4. An iceless refrigerator having a main compartment which is provided with an outer door, and a box-like member having a back which is surrounded by a peripheral flange, said box-like member being turnably .mounted by a hinge which islocated adjacent the inner surface of said outer door, said box-like member being per- .forate, the perforated portion of said box-like member beingsufflciently small in relation to the entire area of the wall of said member so that the temperature which is maintained within said box-like member is normally higher than the temperaturewhich is normally maintained withwhen said outer door is closed, said outer portion of the compartment being of less depth than the inner and'remain-ing portion of said compartment, one of said adjacent walls having shelf means, said inner member being shaped to permit an exchange of refrigerated air between said inner portion of the compartment and the outer portion of the compartment.
