COLD-DISPENSING CAN.

Specification of Letters Patent.

Patcnted Oct. 31, 1911.

Application filed May 12, 1909. Serial No. 495,468.

To all whom it may concern:

Be it known that I, BENJAMIN BRAZELLE, a citizen of the United States, and a resident of Kirkwood, county of St. Louis, and State of Missouri, have invented a certain new and useful Improvement in Cold-Dispensing Cans, of which the following is a specification.

According to the present practice of using ice for cooling purposes, the blocks of ice are uncovered and the water resulting from the melting thereof either commingles with the liquid to be cooled or is wasted. In the latter case, the water runs off at a very low temperature and thus fails to exercise its full cooling effect; and in the former case, it is important that the ice should be perfectly sanitary.

The principal objects of the present invention are to utilize the full coolin effect of the ice, to avoid Waste of materials, to expedite refrigeration of the cooling medium, to facilitate the distribution of the cooling medium in measured quantities, to effect the dry cooling of provisions and the like, and to secure sanitary advantages.

The invention consists principally in refrigerating predetermined volumes of a suitable liquid in thin, hermetically sealed containers.

It also consists in the details and features hereinafter described and claimed.

In the accompanying drawing, which forms part of this specification, and Wherein like symbols refer to like parts Wherever they occur, Figure 1 is a perspective view of a sealed liquid-containing vessel conforming to my invention, a portion of the side being broken away to show the piece of wood provided therein to overcome the of feet of freezing of the liquid; and, Fig.2 illustrates the container in the form of a cartridge for individual use.

According to my invention, suitable containers 1 are nearly filled with water or solutions of suitable salts, leaving an air space in the top of the container. A piece of wood 2is inserted in the container, which is then sealed and exposed to refrigerating action, as in any of the well known processes of manufacturing ice. When the refrigeration has been carried to a suflicient extent, the containers are removed and are ready to be delivered to the consumer. -The use of the air space and of the piece of wood in the container is to permit expansion of the liquid due to freezing and thereby overcome the tendency to rupture the container.

The stick of wood is longer than the width of the can or is otherwise adapted to extend a considerable distance below the surface of the liquid. For convenience in handling, the container is provided with a suitable bail or handle 3.

The most suitable form of container is a Wide flat-sided can of comparatively slight thickness, say about an inch and a half or two inches thick. On account of the thinness of the can, the refrigeration of its contents may be accomplished rapidly; and likewise on account of the large radiating surface, its cooling effect is rapid. The wide flat sides permit the containers to be stacked with stability. 'When thus stacked fiatwise, the total area of exposed surface of the con tainers is reduced by the areas of the meeting sides thereof; and consequently the loss of energy during delivery may be reduced by this method of stacking and likewise the rate at which the containers produce their cooling effect may be controlled by separating or stacking them as desired. As the containers are hermetically sealed, there is no occasion for a separate ice chamber in the refrigerator, as the containers may be placed in the same chamber as the provisions or substance to be cooled or directly in contact therewith. In order to permit this last-mentioned use, it is preferable to make the containers With a sanitary surface. For instance, the containers may be made of aluminum or of other suitable metal coated with tin, nickel or zinc, or with a suitable glaze that will substantially resist the attack of the common organic acids. coating should protect the joints and solder as Well as the body of the metal. These flat containers make convenient rests or supports for provisions or vessels containing the substance to be cooled. As the liquid 0 is hermetically sealed in the containers, there is no occasion to consider sanitary conditions with respect thereto; whereas in the present practice, great precautions must be taken to insure the sanitary condition of the 105 ice, and a fresh supply of distilled or pure .water is needed for every freezing operation. It is, therefore, permissible according to my invention to use any suitable liquid solution in the sealed containers, such for Such 5 instance, as an aqueous solution of sulfate of soda, or of calcium chlorid, or of magnesium chlorid, or a mixture of (glycerin and water. One of the principal a such saline solutions is that their increase of volume due to freezing is considerably less than the increase in volume incident to the formation ofice from plain water; and consequently the tendency to rupture the containers 1s minimized thereby. In the case of the mixture of glycerinand water, the freezing point is below the practical refrigeration temperature, and consequently there is no risk of rupture due to the freezing of the mixture. Another advantage of the present invention is that the contents of all cans may be made uniform or in definite proportions suitable for delivery and use for household coolers; whereby all occasion for weighing is avoided. So, too, as thereis no waste orleaka e from the container, no humidity is introduced into the air surrounding said container.

While fiat cans are preferable for household use, the container may be made in the form of sealed tubes or cartridges for individual use, as illustrated for instance in Fi 2. When such cartridges or tubes are ma e elongated and of small diameter, for invantages of noomeo stance about one inch or less, they are ca able of individual use. For mstance when 1t is desired to cool a beverage, one of these cartridges is inserted in the glass or other vessel containin the beverage, and such cartrid e may e removed whenever desired. or such use cartridges may be made of block tin or other metals that are too expensive for general purposes.

Obviousl my article admitsof consider- .able mod' cation wlthout departing from my invention, and I do not wish to be limited to the specific construction shown and described.

What I claim as m invention and desire to secure by Letters atent is:

As an article of manufacture, a thin flatsided sealed metallic can nearly filled with a liquidadapted to be frozen therein and containing a stick of wood whose length is greater than the width of the can.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses this 10th day of May, 1909.

James A. CARR, JOHN Orr.
