REFRIGERATOR.

Application filed .Tanuary 26, 1921. Serial No. 441L018.

To all whom it may concern Yorkand State ofNew York, have invented certain new and useful Improvements in a Refrigerator, of which the following is a full, clearyand exact specification.

This invention relates, more particularly to a class of refrigerating apparatus.

My invention has for its object primarily to provide .a refrigerator designed to be employed for keeping in a cool temperature perishable food products and the like; in order to prevent spoilage and contamination which would likely occur if the products were subjected to normal or heated temperattire, and which is'oi a: fornradapted to be cooled. by ice in ainanner whereby the cool air-together withtlie ice and the water from the melted ice will be 'efifectually used for refrigerating; the products the invention also providing for pennittingthe water of. the melted ice to be used if desired. These advantages are ac(':omplished,mainly by pro riding: a water'-chamber between an outer casing, having a lid closed open top and an inner casing which is spaced from the outer casing. Interiorly of the upp'erpart of the outer casing abovethe innerjcasing is an ice chamber in communication with the water chamber so that the cooled air of the ice chamber will circulate in the water chamber,

and the water of the melted ice will flow into the water chamber, thereby providing a cooling jacket surrounding the side walls and rear wall of the inner chamber to ac complish aneffectual refrigerating. process interiorly of the inner chamber. The open top of the outer chamber leads into the ice chamber to admit ice, and the inner casifl has a door closed entrance leadin through the wall of the outer casing so that food products may be readily placed in the inner casing.

-A further object ofv the invention is to provide a refrigerator of a simple eflicient and durable construction of a form whereby its parts may be readily cleaned to maintain proper sanitary conditions and which may be made of any suitable material in various sizes and shapes.

With these and other objects in view, the invention will be hereinafter more fully described with reference to the accompanying drawing forming a part of this specification which similar characters of reference indicate corresponding parts in all the views, 1 and will then be pointed out in the claims at the endof the description. I

" In thedrawing, Figure 1 is a perspective of one'form of refrigerator embodying; my

invention. I V

Fig. 2 is'a top plan partly broken away,

of the refrigerator with its lid removed from the ice chamber; and v Fig. 3 is a section taken on the line 33 of F ig. 2, showingthe lid when closed. on

the. outer chamber of the refrigerator.

The refrlgerator has an outer casing-or chamber 10 which is preferably substantially rectangular to provide a bottom 111.

front wall 12. side walls 13, anda real. wall 1e, and this outer chamber maybesupported on annumber of feet. as 15,01 otherwise if desired, The top of the outer chamber isopen, as at 16, to provide an inlet for admitting ice, and in the lower part of the front wall .12- of the chamber may be a large rectangularopening,as 17. I 7

With the outer chamber 1.0 is an inner ca'singorchamber 18 which is alsopreferably approximately rectangular to provide a bottom 18 side falls 19, 20, an upper wall 21 and rear wall 22. The bottom,' side walls and upper wall of the inner chamber correspond to the lengths of the lower edge, side edges and upper edge of the rectangu lar opening 17 of the front w'all12 of the outer chamber 10, and the bottom side walls and upper wall of the inner chamber extend interiorly of the outer chamber from the side edges and upper edge of the opening 17 so thatan entrance 23 to the inner chamber is provided through the opening 17. The bottom. side wallsand upper wall of the inner chamber 18 are also of widthsso that the rear wall 22 of the inner chamber is spaced from the rear wall 1 1 of the outer chamber and so that the bottom 18 is spaced above the bottom 11 of the outer chamber.

The inner chamber18 is ofiless height than the outer chamber 10 to provide an ice chamber 24 above the inner chamber and the open-- inner chamber serving as a bottom to the ice chamber, i

The open top or entrance 16 of the ice chamber 18 is opened and closed by a suitable lid, as 26,-which r'emovabl'y lit's upon the walls of the outer chamber or the lid may be hinged if desired to one of the walls of the outer chamber. g

The entrance 23 of the inner chamber 18 may be opened: and. closed by one or two doors, as 27 and 28, which are hinged, at 29 I and 30, respectively, to the front wall- 12 of the outer chamber, and these ,doors may be releasably locked together by an appjropriate catch, as 31, provided on the doors. Interiorly of the inner chamber 18 may be a number of'sp'aced shelves, as 32', for supporting food products when arranged within the inner chamber 18 for being preserved from spoilagevby refrigeration, and in the lower part ofthe front wall 12 of theouter chamber maybe provided an outlet in the I form of a valve or sp1got32 which is adapted to be operatedfor drawing water from the water chamber 25 at desired periods.- By providing the water and ice chamber 25 and ice chamber 18 in the manner illustrated the cooled air from the ice will circulate in the water and ice chamber and the refrigerating tei'nperature of the water will also be used for keeping the temperature of the interior of the inner vchamber at a degree whereby the products in the inner chamber will be subjected to effectual refrigeration,

To obtain the best results cracked ice or preferably ice and salt should be packed in the chambersbetween the inner and outer casings. Inasmuch as these chambers practical-ly'surround the meat storage chamber,

the same is kept at a low temperature which prevents the deterioration of the meat or other articles stored therein. Such a arrangement also tends to chill the air 0 the "outside of the outer casing, but inasmuch .as the outside air is intended to be at a fairly low temperature the transmission of heat through the outer walls of the device is not excessive and hence expensive heat insulation on the outer walls thereof is dispensed'with.

In the foregoing description, I have em A refrigerator having a non-insulated sheet metal outer casing and: asheet metal inner casing spaced from theou-ter casing forming a top compartment and communicating side compartments adapted to receive ice to chill both the contents of the inner I compartment and the air on the outside of the outer compartment.
