Copcman, Flint, Mich, assignor to Copcman Laboratories Company, Flint, Mlcln, a corporation oi Michigan Application July 13, 1932, Serial No. 622,305 Renewed May 26; 1936 2 Claims. 101. 62-1085) This invention has to do with the of ice and with the storing of the same prior to use; The invention relates particularly to a method'and device for so making and'storing 5 the ice. I
The invention aims to provide for the making of a substantial amount of ice which is par ticularly advantageous for soda fountains and- I the like which are mechanically refrigerated. At 10- places where cold and iced drinks are dispensed, many drinks require the use of cracked ice and at such places, as. for example, soda fountains where the syrup, extracts,-carbonated water and the like and ready mixed drinks are mechanical- 15" 1y refrigerated; there is no means oi providing ice for use directly in the drinks or otherwise. The mechanical refrigeration has for one purpose, the elimination of the use of ice, and consequently the elimination of the time and trouble and in- 1, convenience of ice delivery and the packing of the parts to be refrigerated with ice. This purpose can not be achieved in its entirety however where ice must be used in the drinks or otherwise.
The present invention, therefore, provides for 5 the manufacture and storage of ice at such places, and the invention may be carried out by the provision of a suitable insulated cabinet having preferably two or more compartments, at least one of which may be used for freezing of the ice,
30 preferably in cube form, and at least one end of which may be used for storage of the e, so that there is always an available supply. More particularly, the invention contemplates the use of solid (30:; as a cold producing medium for 35 freezing the ice, and the ice may be frozen until it is at an extremely low temperature, materially below the freezing point of water so that when placed in the storage compartment the residual refrigeration, which results from the abnormally 40 cold ice, aids in maintaining the same in cold condition. This refrigeration of the storage compartment may be supplemented in the cold-producing effects of the solid 002.
Fig. l is a perspective view of a cabinet con- 45 struct'ed in accordance with the invention, showing one compartment closed and another com- Fig. 4 is an elevation of a removable unit showing ice cube trays and blocks of solid carried 5 thereby with some of the parts'shown in section.
Fig. 5 is a plan view of the modified arrangement.
-The cabinet is shown at I and it has in the present instance two compartments, one illustrated at 2 and one at 3, with covers therefor 5 shown at t. This cabinet is preferably insulated by insulations 5. A partition 6 may divide the chambers, and a passageway 1 may be provided between the compartments for purposes which will presently appear. 10
A tray-receiving device more or less of skeleton construction may be provided for. each compartment; such a device is illustrated inFig. 4
r and it may have vertical stays Ill preferably three in number as shown in-Fig. 3 for supporting in spaced vertical relation a plurality of shelves ll. One end may be reinforced by a ring l2 and the same may be provided with a ball or handle l3. The ice to be frozen advantageously is so frozen in the form of cubes, and for this purpose ice I cube trays it may be provided and placed on some oi the shelves. On other shelves, blocksit of solid CO2 may be located, and as shown in Fig. i, such blocks may have a covering therefor such as paper or the like. The arrangement shown in Fig. 4 illustrates the blocks of CO2 and the ice trays disposed on alternate shelves. This is, thought to be an advantageous arrangement although the principal idea is to provide enough C0: to freeze the water in the desired time. Such a supporting device containing the ice cube trays lull of water and the blocks of solid CO2 may be disposed in the compartment 2, as illustrated in Fig. 2. Another similar'supporting device and which in fact may be identical with that 5 shown in Fig. 4, may be disposed in the com- .partment t, and all of the shelves for this supporting device may contain ice cube trays l5. The shelves, as illustrated in Figs. 1 and 3, may
be ol screen construction. 40
In the use of the device the trays full of water and the blocks of solid 002 may bepositioned on a support and disposed in the compartment 2. This arrangement provides for freezing the water in a relatively short time, and preferably the trays with the solid C0: are maintained in the com partment until the ice cubes are at a temperature materially below the melting point of the water.
. By removing the supporting device the trays with the frozen cubes may be transferred into the storage compartment 3 by shifting the trays from one supporting device to the other. Then empty trays maybe-filled with waterfand placed back into the freezing chamber. Obviously, the empty trays may be obtainedby reason of previous use of ice cubes. The ice cubes are stored and maintained in the compartment 3 and may be removed therefrom as used. Due to the fact that the ice is at an abnormally low temperature when first introduced into the chamber I, there is what may be termed a residual refrigerating eil'ect sufficient to maintain the ice frozen over a material length of time. When the ice cubes are taken out of the freezing compartment the temperature may be so low as to not permit of removing the ice cubes from the trays with any degree of facility. After they have been stored in the storage compartment and the temperature has risen considerably they then may be removed with facility and used.
The residual refrigerating effect obtained by the abnormally low temperature of ice may be supplemented by the solid C02. This may be governed by the insulation qualities of the partition 8, and if it be found necessary, a connecting passageway I may be provided between the two chambers in order to provide a requisite supplemental refrigeration. However, the passageway I may be dispensed with and the insulation qualities of the partitions 6 properly designed to provide the requisite supplemental refrigeration.
It is within the invention to provide a cabinet with more than two compartments although the one described involving two compartments will suffice for making a complete disclosure of thelarly in the transfer of the ice cubes from the refrigerating compartment to the storage compartment, it may be pointed out that the ice trays may be transferred'all at one time, or one or more at a time depending largely upon the desires, of the user and the length of time the trays were in the freezing compartment.
I claim:
1. A device substantially for the i po e described comprising an insulated cabinet having vertically disposed compartments therein opening through the top of the cabinet, cover members for the compartments, one compartment being adapted to receive solid carbon dioxide for freezing liquid, an adjacent compartment being adapted to store frozen liquid, and a partition dividing off the said two compartments, said partition being vertically disposed and serving to define wall portions of the said compartments, and said partition having a passageway therethrough interconnecting the chambers for facilitating transfer of heat from one compartment to another.
v 2. An ice cube forming, storing and dispensing cabinet comprising an insulated compartment, a cover member for the compartment, said compartment being adapted to receive solid carbon dioxide for freezing liquid and for producing a temperature adjacent the liquid being frozen considerably below freezing, and a second insulated compartment adapted to store the liquid frozen in the first compartment, said compartments being so positioned relative to each other and the insulation therebetween being so arranged that a portion of the relatively low refrigeration produced in the first compartment is utilized for maintaining the temperature of the second compartment just low enough to maintain the stored liquid in frozen condition.
