UNITED STATES MARTIN FREDENHAGE,

or LA GRANGE, ILLrNoIs.
Application led September called dry freezing or4 refrigeration, thatis,-
in which no exposed ice or salt is used, the refrigerant being kept in a sealed container adapted to be placed in a suitable insulated container. 4
' Heretofore in handling and delivering ice cream, where it is necessary to pack it so as to keep it`cold for a period of time longer than the ordinary melting period, it has been the practice to pack the cream in afpail or can surrounded by chopped ice, which is salted. This is nota very clean or sanitary method of handling the cream, because the ice melts and sometimes the salt water getsinto the cream or runs out ofthe container.
In my improved refrigerator and method of refrigeration, this is done away with as'the refrigerant is kept in a sealed container and thus the entire method is clean and dry.
In the accompanying drawings, I have shown the preferred form of refrigerator- Fig. 1 being a perspective View of the refrigerator, showing the cover removed;
Fig. 2 is a sectional view through Fig. 1 along the line 2-2 54 Fig'. 3 shows the outertubular section with the end flaps unfolded;
Fig. 4 shows the inner tubular section of the refrigerator with the end flaps unfolded; and
Fig. 5 shows a form adapted to beused for assembling the tubular sections 3 and 4.
Referring now more in detail to the refrigerator as illustrated, it comprises preferably inner and outer tubular sections, preferably made up of a suitable fiber board, Fig.
3 showing the outer section 10 having downwardly extending portions 11-12 from eacl y of-thc four wallsl and adapted to be folded inf wardly and overlappedv so as to provide a suitable bottom, said overlapping sections being' suitably secured, preferably by a waterproof cement, and the meeting edges or cracks sealed.l The top extending portions 13-14 of the section 10 are adapted to be folded inwardly as indicated.

purposes. The lower ends 16-17 ofsaid" inyner section are adapted to be folded inwardly and overlapped. They are then suitably secured and sealed, preferably by awater-proof cement. The upper ends 18-19 are adapted to be folded outwardly as shown, so that they may overlap with the upper ends 13-14 of the outer section.
'To assemble the tubular sections I provide,
. y 1,701,323: ENT OFFICE.
a hollow block 20 constructed so that the in 4 ner section 15 may be inserted inside the block and the outer section 10 placed over the block. Before turning the ends of the-section over I place strips of wood as 21-22 around the four sides, then fold or turn the upper extensions 13-14 and 18-19 so that they overlap. I- then drive nails 23 through the overlapping' portions into the wood sections 21-22, thereby firmly holding the parts together. I then draw the wood block 20 out pf the assembled sections. i
The bottom flaps 16-17 of the inner section 15 may be turned and sealed, as already indicated, either before or after assembling with the section ,10.n But after the block 20 is drawn out of the assembled sections, andA before the bottom flaps 11-12 of the outer section 10-are sealed, I inserta suitableinsulating material 23 in the 'intervening space The outer or food container is now completely assembled, with a central opening ofv a suitable size. b
Where it is to be used for ice cream', I preferably make. the opening of a size to take one or more bricks, leaving sufficient space therein to insert a'container with refrigerant, as will be more fully described.
having an insulated face 27 and a hair ,felt `block 28Vfof a size to lit snugly into the cenltral opening of the container so as to be held thereon. Now as to the refrigerant, I preferably provide a container adapted to hold a solution which maybe frozen therein so that lthe entire element consists of a cold, dry refrigerant.' To this end I provide a metal can 29,
In order tofclose the container I provide a suitable'top made up oftawood cover 26 arranged to receive the refrigerant element, this being preferably a brine solution adapted to be frozen in thecan to about zero and which will not melt under about 18 degrees Fahrenheit. A Solution having :a specific gravity of approximately 50 on the salinometer works well and comes within the aforesaidv temperatures, thereby providing a frozen solution which will begin to melt at about 18 degrees Fahrenheit, which is the temperature at which good ice cream will freeze. This I find very suitable for use in connection with ice cream where it is to,be packed and delivered 'in a local territory.
Thus in the use of the refrigerator and carrying out my method of refrigeration, I -plac'e the article to be delivered, such asi a brick of ice cream 30 therein; I then insert the frozen refrigerant 29 into the container and place the cover 26 thereon.
It is now ready for delivery and may be very readily handled, being clean and dry and maintalning the ice cream below melting point for a period of time sufficient to cover ordinary conditions of delivery and use.
What I claim as new and desire to secure by United States Letters Patent is:
l. A refrigerator casing comprising t'wo tubular sheet material sections, one inserted in the other, the inner section having end por tions turned inwardly and overlapping to form a sealedbottom, the outer section having end Iportions turned inwardly land overlapping to form a sealed bottom, said sections having intervening insulated spaces between t-he walls, and means for securing the sections at 'the'top to seal the same. l
2*.' A refrigerator casing comprising two tubular sheet material sections, one inserted in the other, the inner section having end portions turned inwardly and overlapping to form a sealed bottom, the outer section having end portions turned inwardly and overlapping to' form a sealed bottom, said sections having turned over overlappingends secured together to seal the top across the in-a tervening space between the walls.
3. A refrigerator casing comprising two tubular sheet material sections, one inserted in the other, the inner section having end portions turned inwardly and overlapping to form a sealed bottom, the outer section` having end port-ions turned inwardly and overlapping to form a sealed bott0msaid inner section having end portions turned outwardly and said outer section having end portions turned inwardly with said inner and louter portions overlapping and secured to seal the top across the intervening spac between the Walls. A In witness whereof, I hereunto subscribe my name this'QOthv day of4 August, A. D.,
