vCAN' FOR FREEZING ICE.-

Application filed April 18, 1922. Serial No 555,430;

To all whom t may concern Be it known'that I, REUBEN WINFREE, a citizen of the United States, and a resident of Salisbury, inthe county of Ch-ariton. and State of Missouri, have invented certain new and useful Improvements in Cans for Freezing Ice, of which the following is a specilication. i l

This invention relates to cans for freezing ice in such amanner that blocks of ice canbe formed by natural temperature, vor by freezing mixtures Ain a vat, in less time and at less vexpense than is possible with the conventional cansin common use.

An object of the invention is to produce an ice can havin-g a central opening therethrough so that a' greater superficial area is presented vto the refrigerant.

Another object is to produce any ice can comprising a container 'having an opening in the bottom of the same Vand a wall surrounding such opening and extending upwardly yinto the container.

Another object is to provide a ca-n for freezing ice, comprising acontainer having an opening in the bottom and a wall sur rounding such opening and'fextending upwardly into the container, said Vwall inclined inwardly.

Another object is to provide a can for freezing ice c omprising a container having an opening in its bottom having a wall surrounding such opening and extending upwardly into the container, and having an outer surrounding wall extending upwardly' from the bottom and inclined outwardly providing a can having its upper end larger than its lower end.

Other objects and advantages will appear as the description of the construction and arrangement of parts proceeds and as shown in the drawings forming a part hereof, the novel characteristics of the invention being set forth in the appended claims.

In the drawing: v l

Figure 1 is a vertical longitudinal section of the can;

Figure 2 is a top plan view of the same;

Figure 3 is an end view.

In carrying my invention into effect I provide a container 10 .of suitable size and shape, such'shape being generally rectangular and elongated, the same Vbeing preferably larger at the top than at the bottom in order to facilitate theremoval of the ice*` block. Y f

The can has' a bottom''ll and the-top is.` turned over andv outwardlyto formV aflange 12,- and'v aband 13 is put aroun'dfthe can immediately beneath flange 12 and riveted orA otherwise suitably secured, to give it strength ,i lifting holes 14 are' punched through the opposite sides and the-band, said holes` being about six (6) inches from; theAVA longitudinalcentenof the can. An elo'ngated rectangular opening 15 is made in the' A bottom 1'1 and theedges" turned upward to forinan upright flange 116 over which"v is' placed the inner wall 17 ofthe inner can The top of thel inner can formedby the walls 17l is slightly smaller thanat the loot-- tom and is turned inwardly' to form a horizontal flange-19 to the underside of whichis rivetedand soldered the band or frame 2O to reinforce and strengtlien'- same.

By the'construction and arrangement ofthe parts as hereinbefore set forth, an annular chamber 21 of elongated rectangular shape is provided which is larger at its upper end than at its bottom so that it flares upwardly to facilitate ready removal of the ice block, and the upper ends of both the inner and outer walls are flanged and reinforced.

By providing .the inwardlly projecting flange 19, on the inner can walls 17, splashing or running over of the brinev or other refrigerant when such is used, is prevented, and the ice block protected from such re frigerant. These flanges falso provide a' means to receive hooks or tongs for lifting the can or transporting the same. In the absencev of hooks or tongs, a bar may be inserted in the opening 15,l and turned 'to engage under flanges 19 to lift the'can. The lifting function can alsorbe carried out with the flange 12 on container 10.

In the practical use of the device, the space 21.0f the can is rfilled with water up to about level of the flanges 19, and then set in position to be frozen either by natural air or set into a tank of brine or other refrigerant, the depth of such refrigerant being such that its upper surface is just below the reinforced flanges 19.

The usual manner of freezing blocks of ice is in large cans without a core and the time required to freeze ice is equal tothe square of the thickness to be frozen. That is, it takes four times as long to freeze two inch ice. as it does to freeze 'one inch, hence with the ordinary type of can in which the ice begins to freeze at the bottom and freezes two or three inches before there is any sign of freezing at the top it will take much greater time to freeze the upper half of the block than it kdoes the lower half, the trouble being to freeze the center of the block.

By my construction this trouble. is removed as the center of my can is an open space filled with brine which is the refrigerant and a greater superficial area -of water is presented for action of the refrigerant.

From the above it will be plain that by the use of my improved can, ice can be frozen in much less time and at less expense.

Having thus described my invention what I claim is: Y

1. A can for freezing ice in blocks, comprising a rectangular container having outwardly inclined outer walls and a rectangular opening in its bottom, an upwardly eX- tending flange surrounding said opening, 'an inner wall surrounding said vflange and rigidly secured thereto to form a tight joint, said inner wall being inclined inwardly and extending upwardly into the container, the

upper end of said inner wall being provided with an inwardly projecting annularl flange 'vided with hoisting openings, and a rectangular inner wall Surrounding such opening in the bottom, inclined inwardlly and extending upwardly into said container, said inner and outer walls `defining an annular freezing chamber larger at the. topthan at the bottom. f

3. A can for freezing ice in blocks comprising a rectangular container having outwardly inclined outer walls and a rectangular opening in its bottom, an upright flange'surrounding said opening, a rectangular inner wall surrounding said upright flange and having a horizontal flange at its lower end seated on the bottom of the container and rigidly secured thereto to form a tight joint between the, bottom and the flange, said inner wall inclined inwardlly and extending upwardly into the container and defining a rectangular refrigerant chamber open at itsA top and bottom.

In testimony whereof I have hereunto set my hand this lday of VDecember 1921 in the presence of two subscribing witnesses.
