Application tiled July 12, 'lt'. Serial No. 205,145.

This invention relates to new and useful improvements in devices used in the manufacture of ice, and more particularly to such devices as are used in household rej frigerating apparatuses.

It is well known that in household refrigerating apparatuses of the present day, provision 1s made for manufacturin small cubes \of ice for table use. The rawers h which are usually provided for this purpose have partitions which form a plurality of compartments in which.the ice 1s made. These small blocks of ice are removed and placed in liquids,y or otherwise used, for the purpose of cooling. The pan, in which the compartments are located, vmust be rov1ded with water to be frozen. This entails labor, in removing the ice blocks, and also the danger of spilling water from the pan while replacing the same in the refrigerator.

' The principal object of the present invention is to eliminate the objectionable feature ofs'pilling water, and the other objectionable 1AJfeatures that are present when the substance to be frozen is placed directly in the pan.

Another object is to provlde a receptacle in which a quantity of water, o r other suit# able substance, is hermetically sealed, such receptacle being placed in the tray of the refrigerating unit of the refrigerator. When the liquid in such receptacle is frozen, the receptacle in placed in the liquid to be chilled, or otherwise used.

Another object is to provide a device of this character wherein the liquid, contained therein, is adapted to be frozen as many times as desired, thus obviating changing the contents..

Another object is to provide a device of this character which is readily ada ted for use in any of the ordinary ice ma ing refri erators now in use.

f ther objects and advantages wi'll be apparent from the following description when taken `in connection with the accompanying drawing.

Inthe drawing: Figure 1 is a vertical sectional view of the freezing chamber of a refrigerating apparatus, showing my invention 1n place, the side of the drawer being partly broken away.

Figure 2 is .a perspective view of one of the ice receptacles, removed from the drawer, and partly broken away.

Figure 3 is a view of the spherical form of the container.

Referring particularly to the accompanying drawing, 10 represents the freezing chamber of a refrigerating apparatus, of the household type, which is provided with a compartment 11, which compartment has an other suitable substance, and then hermetically sealed, so that the contents may not escape. A number of these -receptacles are placed in' the drawer 13, and such drawer inserted in the freezing chamber, and per.

mitted to remain until the contents have become frozen. Upon withdrawing the drawer any number of the receptacles may be removed therefrom, and such receptacles placed directly within the liquid which is to e chilled. After having been used, the receptacle or receptacles are replaced in the drawer, which is then returned to the freezing chamber. This may be repeated as many times as desired, when the contents of the receptacles have become frozen, thus obviating the necessity of refilling.

In Figure 3 there is shown the spheric-al form of the container, for containing the freezable substance. This form has the particular advantage 'of contacting with the drawer at a single point, only, thus exposing the maximum amount of surface to the freezing effects of the surrounding medium, and thereby hastening the freezing of the contents of the receptacle. The converse is also true, permitting the substance to be cooled, to be exposed to a maximum cold surface. This shape also offers less resistance to the stirring action of a spoon, when used in a drink, in a glass, such as iced tea., or the like, where the sugar is to be moved from the bottom of the glass.

What is claimed is:

1. A process of forming ice in small units in a refrigerator having a freezin unit including a freezing crypt therein, w ich consists in entirely enclosing a congealable substance in small containers, and placing said containers within the crypt until the substance has been frozen.

2. A process of forming ice in small units in a refrigerator having a freezin unit including a freezing crypt therein, W ich consists in entirel enclosing a con ealable substance in smal substantially g obular containers, and lacing said containers within the crypt until the substance therein has been frozen.

3. A rocess of forming ice in small units in a regigerator having a freezing unit including a freezing crypt therein, which consists in enclosing a con ealable substance in small hermetically sealed containers, and placinv .said containers Within the crypt until tie substance has been frozen.
