This invention relates to an ice can, such as a can used for making cubes of ice, the general object of the invention being to provide a resillent member in the can which is so constructed and arranged that it will allow expansion of the freezing water and prevent bulging of the can.

Another object of the invention is to provide means whereby the partition members of the grids can be moved, after the grids with the cubes therein are removed from the can, so as to easily and quickly release the cubes from the parts of the grids.

A still further object of the invention is to provide perforated partition members for use in a can having a plurality of grids therein for separating some of the grids from the others, the perforations permitting the freezing water to reach the resilient member so that this resilient member will permit expansion of the cubes on the far sides of the partition members to prevent bulging of the sides of the can.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.

In describing the invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which:

Figure 1 is a longitudinal sectional view through a can provided with the invention.

Figure 2 is a vertical longitudinal sectional View and taken at right angles to Figure 1.

Figure 8 is a vertical sectional view through Figure 7.

Figure 9 is a fragmentary view of one of the partition members with the perforations therein.

Figure 10 is a fragmentary perspective view of the resilient member.

In these drawings, and referring to Figures 1, 2, 3, 4, 5 and 6, the can is shown at C and said can is open at its top as usual and the can shown in Figures 1, 2, 3 and 5 is of a size to receive a pair of grids G each of which includes a plurality of longitudinally extending members I and a plurality of transversely extending members 2.

As is well known during the freezing operation the expansion of the freezing water causes the sides of the can to bulge, thus rendering the can incapable of being used after a short time. In order to prevent this bulging of the can I provide a resilient member 3 made in the form of a fiat plate which extends longitudinally in the can and this resilient member is contained in a frame 4 of metal, the parts of which are of channel-shape in cross section to receive the edges of the resilient member as shown more clearly in Figure 10. Preferably the resilient member is formed of waterproof sponge rubber and the relative sizes of the frame 4 and the members of the grids are such that the grids will contact the frame and not the rubber or resilient member 3. Also, the parts are so arranged that the frame 4 will hold the outer edges of the members of the grids in contact with the inner walls of the can so that no ice can be formed between the edges of the grid members and said inner walls of the can. Thus during the freezing operation the expansion will take place against the resilient member which will give to permit this expansion and this will prevent bulging of the sides of the can.

As more clearly shown in Figure 4, each member I is formed of a major part l and a minor part i" which are held in spaced relation to form a narrow longitudinally extending slot 6 and these parts I and l" are held in this position by the transversely extending end members 7 which are suitably connected with the members l and I". The member I on its inner edge is provided with a plurality of spaced slits 8 which open out into the slot 6 and the transverse members 2 are provided with the slits 9 in both side edges so that by turning a transverse member 2 and passing one end through the slot 6 until a long slit 9 comes opposite a notch or slit 8 with a short slit 9 opposite the member 1" the transverse member can be turned to interlock with the member I as shown in Figure 4. This will firmly hold the parts of each grid together so that they will not fall apart when removed from the can and when freed of the ice.

A notch I is formed in the top of each member I at one side thereof with the upper wall of the notch sloping downwardly and inwardly as shown in Figure 4 and these notched parts extend above the resilient member and its frame and an elongated bar or key member I i, see Figure 6, having an upstanding handle l2 at its center, is adapted to be passed through the aligned notches of the members E, after the grids, the resilient member and the ice cubes are removed from the can. After the bar is placed in the notches the bar is rocked by the handle I2 which forces the member I of one grid away from the members I of the other grid and both grids from the resilient member and this imparts movement to the transverse members 2 so that the cubes of ice can be easily and quickly re leased from the grids.

A cover I3 is provided for covering the top of the can and said cover has a gasket i4 therein to engage the top of the can, with the flanges of the cover extending over the reinforcing strips at the top of the can on the exterior thereof.

Preferably an opening I3 is formed in the top of the can to drain the air and water therefrom so as to maintain the water level in the top of the can below the notched parts at the upper ends of the members I so that no ice can form in the notches. Air during the freezing operation can pass to the sides of the resilient member through the slits and openings formed in the grid members and this air can pass upwardly along the sides of the resilient member and pass through the grooves i6 formed in the top member of the frame 4 of the resilient member, as shown in Figure 10. Thus no air can be trapped in the can and thus crystal ice is formed.

When a multiplicity of grids is used in a large can the pairs of grids between the resilient member and a side of the can is separated by a partition plate I8 provided with a multiplicity of perforations I9, see Figures '7, 8 and 9, so that water can pass from the outer grid through the perforations and thus reach the resilient member and thus expansion in the outer grid is taken care of by the centrally arranged resilient member and this expansion will not bulge the sides of the can. In this case, some of the longitudinal members of the grids have notches ID in both sides thereof as shown in Figure 8, so that a bar I I can be used for separating each grid from i an adjacent grid. In other respects this form of the invention is similar to that first described.

Thus it will be seen that I have provided simple means for preventing the expansion action during the freezing operation from bulging the sides of the can as this expansion is compensated for by the resilient member and the parts of the grid do not contact the resilient member as these parts all contact the frame 4 and this frame holds the outer edges of the grid parts snugly against the internal walls of the can so that no ice will be formed between the edges of the grids and the can, thus enabling the internal parts to be easily removed after the water has frozen. The member II enables the grids to be easily separated from the ice cubes and from the member 3 and its frame 4 and all air can readily escape through the openings in the grid members and the perforations in the partition plates Hi. When such plates are used and this air will escape through the grooves IS in the top of the frame of the resilient member.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts provided that such changes fall within the scope of the appended claims.
