JOSEPH MILLER, OF IVIIHNEAPOLIS, MINNESOTA.

TAN K FOR REFRIGERATORS.

Application filed February 11, 1922.

To all whom it may concern.

Be it known that I. 'losrrir MILLER, a citizen of the United States, residing at Minneapolis, in the county of Henuepin and State of Minnesota, have invented certain new and useful improvements in Tanks for Refrigerators, of which the following is a specification reference being had therein to the accompanying drawings.

This invention relates to an apparatus for cooling air in a refrigerator or ice-box. or in a storage compartment, whereby a great amount of cooling possibi ities is obtained by the use of a relatively small quantity of ice and salt. or the like.

Another object of the invention is the construction of a tank apparatus for placing in a refrigerator of any desired type, which tank apparatus is provided in its bottom with a number of flue-structures for allowing air to have a greater area. of contact against the tank containing a refrigerating or cooling compound or element, such as a suitable brine. or ice and salt.

lVith these and other objects in view. my invention comprises certain novel combinations, constructions and arrangements of parts as will be hereinafter described illustrated in the accompanying drawings. and more particularly point-ed out in the appended claims.

ln the drawings:

igure l is a sectional view of a refrigerator. showing my tank apparatus in longitudinal section.

Figure 2 is a sectional iew. taken on ine Fig. 1. and looking in the direction of the arrows.

Figure 3 is a longitudinal. sectional view of the tank apparatus through one of the tluestructures thereof.

Figure 4. is a sectional view, taken on line 4.-+l;, Fig. and looking in the direction of the arrows.

Figure 5 is a perspective view of the tank apparatus with the top removed.

Figure 6 is a perspective view of the top of the tank apparatus.

Figure 7 is a perspective view of the any iliary casing of the flue-structure.

Referring to the drawings by numerals, 1 designates the refrigerator, which may be of any desired or ordinary type, and into which I place tank apparatus 2. The tank apparatus comprises a body 3 which is provided with a bottom 4 and with a top 5.

Specification of Letters Patent.

Patented May, 9, 1922.

Serial No. 535,845.

The top 5 includes a cover 6, which cover 6 is provided with fastening devices 7 for holding the cover in place upon the top, and with a suitable handle 8. The refrigerator 1 is provided with a cover 9 directly above (Fig. 1) the cover 6.

The bottom 4 of the body 3 includes a plurality of fiuestruct ures 10. Each. fluestructure 10 comprises a primary casing 11 and an inner,.auxiliary casing 12. Between the contiguous flue-structures 10 and the flue-structures and the side walls of the body 3, are formed. preferably. V-shaped troughs 13 that, empty at one end into the drain 14 of the tank. A suitable drain pipe 15 is connected at its inner end to the drain 14 of the tank, with its outer end extending beyond the outer face of the refrigerator 1, Fig. 1.

Each auxiliary casing 12 comprises parallel sides 16 that are connected at their upper edges by a substantially inverted, V- shaped, apertured top 17. Extending'from the lower edges of the sides 16 are a plurality of legs 18, which legs are bent at an angle and are soldered to the bottom of the troughs 13 of the bottom structure 1 of the body 3. These legs 18 holdthe auxiliary casing in a spaced relation *ithin theprimarv casing 11, so that air can circulate between the primary and auxiliary casings of each flue-structure. indicated by the arrows in Fig. 1. By reason of this structure, a greater area of metal surface is exposed for air iii-the refrigerator to come in contact with, andas a suitable refrigerating element is in the body 3 against the'fluestructures, a very etiicient action is obtained by reason of the greater area of refrigerating surface being exposed, so that the air in the refrigerator can come in contact therewith.

Suitable packing 19, Fig. 1, is placed around the tank apparatus, to prevent any brine or salt water spilled over or upon the top 5 from running down into the lower portion of the refrigerator.

It is to be noted that the inner end 21 (Fig. 3) of each flue-structure is closed, whereas the outer end 22 is open, but when the tank apparatus is in the refrigerator 1, the open end 22 of each flue-structure is closed by the packing 19, so that no brine or water passing from the top 5 can pass into the bottom or lower part of the ice-chest or refrigerator 1.

My apparatus will keep ice cream from melting, at a minimum expense, since ice cream can be placed in receptacles in the lower part of the refrigerator 1, and by reason of the great exposure of the metal surface of the bottom structure of the tank apparatus, the air in the refrigerator is kept at low temperature.- or degree. The same principle can be adopted for large refrigerating compartments, or plants, as it is optional with the constructor to use as many, or as few, of the flue-structures as he desires.

While I have described the preferred em bodiment of my invention, and have illustrated the same in the accompanying drawings, certain minor changes or alterations may appear to one skilled in the art to which this invention relates, during the extensive manufacture of the same and I, therefore, reserve the right to make such alterations or changes shall fairly fall within the scope of the appended claims.

What 1 claim is:

1. In an apparatus of the class described,

' the combination. of a body provided with a bottom, said bottom comprising a plurality of V-shaped troughs and a plurality of flue-structures having ll-shaped tops, a drain formed in said bottom, and an outlet pipe communicating with said drain.

2. In an apparatus of the class described, the combination of a body provided with a bottom, said bottom including a flue-structure, said flue-structure comprising a primary casing, an auxiliary casing within said primary casing, said auxiliary casing comprising sides and an apertured top, legs formed upon said sides and connected to portions of the bottom of the body, a drain formed in said bottom, and means for draining said drain.

3. in an apparatus of the class described, the combination of a body provided with a bottom, said bottom comprising a plurality of V-shaped troughs and a plurality of fluestructures, each flue-structure comprising a primary casing and an auxiliary casing, each auxiliary casing comprising parallel. sides with an integral, substantially ll-shaped, apertured top, legs depending from each side, said legs bent and fastened to portions of the Vshaped troughs, a drain in said bottom and under ends of the troughs, and draining means connected to said drain.

a. In an apparatus of the class described,

the combination of a body provided with a bottom, said bottom including a plurality of flue-structures, each flue-structure comprising a primary casing closed at its top, an auxiliary casing positioned within the primary casing under its top and having its lower end open, means securing the lower portions of the auxiliary casing fixedly to the primary casing, said bottom including a drain. and an outlet pipe connected. to said drain.

In an apparatus of the class described, the combination o'l a body provided with a bottom, said bottom including a plurality of flue-structures, each flue-structure comprising an inverted, substantially V-shaped primary casing, closed at the top, an invcrted substantially \l-shaped hollow auxiliary casing entirely within said primary casing and permitting air to pass therethrough, said bottom provided with a drain, and an outlet for said drain.

6. In an apparatus of the class'described, the combination of a body provided with a bottom, said bottom including a plurality of flue-structures, each flue-structure comprising a primary casing closed at the top, a hollow auxiliary casing fixedly secured entirely within the primary casing and permitting air to pass therethrough, said bottom provided. with a drain contiguous to the same ends of all of the flue-structures, and an outlet for said drain.

In testimony whereof I hereunto afiix my signature.

JOSEPH MILLER.
