ICE-CREAM FREEZER.

Specification of Letters latent.

Patented Apr. 27, 1920.

Application filed March 22, 1918. Serial No. 224,010.

To all whom it may concern:

Be it known that I, MITCHEL A. ABEL, a citizen of the United States, and a resident of Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Ice Cream Freezers, of which the following is a specification.

This invention relates to ice cream freezers or molds, and the primary object of the invention is to provide a freezer structure in which the cream, flavoring and other ingredients of the ice cream are placed, in

liquid form in a transparent or glass mold after which a base member is securely attached to the open end of the mold and the mold and base are packed in a suitablecontainer containing ice for freezing the contents of the mold.

Another object of this invention is to provide a recess formed in the upper face of the base of the mold in which recess is positioned a. rubber or: suitable cushioning washer for co-action with the means for securely clamping the mold in connection with the base to form a fluid tight joint at the engaging portion of the base and molds.

A still further object of this invention is to provide a mold, the side walls of which are slightly inclined, so that after the contents of the mold has been frozen, the applying of heat to the exterior of the mold will melt the portions of the cream adhering to the interior of the mold and allow the latter to be lifted off the brick of ice cream, leaving the latter upon the base, for serving.

Other objects of the invention will appear in the following detailed description, taken in connection with the accompanying drawing forming a part of this specification, and in which drawing:

Figure 1 is a side elevation of the improved freezer.

Fig. 2 is a vertical longitudinal section through the freezer.

Fig. 3 is a perspective view of the mold, and

Fig. 4 is a perspective view of the means carried by the mold for engagement with the base to securely clamp the mold in place upon the base.

Referring more particularly to the drawing, 1 designates the main body of the supporting. base of the freezer structure which has a plurality of supporting legs 2 attached to the under surface thereof. The upper surface of the main body 1 of the base is provided with an annular recess 3 in which is seated a gasket 4 against the upper surface of which gasket the lower edge of the mold 5 engages when the mold and base are in proper relation for the freezing of cream in the mold. An upstanding flange 6 is formed about the base 1 outwardly of the recess 3 and its upper edge projects above the upper surface 7 of the body 1 of the base, as clearly shown in Fig. 2 of the drawing.

The mold or form 5 is preferably constructed of glass and its side and end walls incline or converge as they extend toward the top 8 of the mold.

The mold or form 5 has an outstanding rib 9 formed thereon, which rib extends entirely about the mold a relatively short distance above the lower edge thereof and provides an abutment against the upper surface of which the rectangular wire frame 1.0 rests. The rectangular frame 10 is constructed of'wire and engaged to fit snugly about the form 5. Each side of the rectangular frame 10 has a pair of eyes 11 formed therein by bending the wire and substantially U-shaped clamping rods or wires 12 are connected to the eyes 11 by loops 13 which are formed upon the ends of the legs of the clamping wires 12 and engage through the eyes 11.

The base 1 has depending lugs or projections 15 formed upon the under surface of the inclined end portion of the body of the base, the under surface of which lugs are curved to permit the riding thereover of the bight portions of the clamping wires 12, to permit the latter to be moved into the recesses 16 where they are securely held for clamping the mold or form 5 in firm engagement with the base 1 to prevent accidental disconnection between the mold and the base during the freezing operation of the contents of the mold and also to force the lower edge of the mold against the gasket l in such manner as to form a fluid tight joint.

In the use of the improved freezer, the mixture of cream, flavoring, etc., of which the ice cream is formed or any other suitable type of mixture to make ices, or other frozen confections is poured into the mold 5 when the latter is in an inverted position, resting upon its top 8. The base 1 is then positioned over the open end or edge of the 222 A memes wires 12 are forced over the curved surfaces of the cam locks 15 into the recesses 16 which securely clamp the mold in place with respect to the base. The entire freezer is then placed in a container and ice is packed about the freezer, the latter being permitted to remain in the container for practically an hour and one-half -or two hours, at the termination of which time-the contents of the mold will be properly frozen. After the contents of the mold are frozen, the freezer is removed from the container and immersed in cold water to cleanse the exterior for removing ice and salt whereby the same will be prevented from entering the confection when the freezer is opened.

After the freezer is washed heat is applied to the outside of the mold 5 for a very short period which will melt the portions of the ice cream or confection which might cling to the inner surface of the mold, allowing the mold, after the members 12 have been released, to be lifted off the brick of the ice cream or other confection, which brick remains upon the surface 7 of the base. 1 from which it may be served being cut down in slices as desired. 7

If it is so desired, the base 1 may be provided with artistic ornamentations to add to the appearance thereof. v

Having thus fully described the invention what is claimed is:

In a confection freezer, a base provided with an annular channel in its upper surface, an' annular flange surrounding said channel and projecting above the upper face of the base, amold having one side open and having its edges about the open side engaging in said channel, an annular rib formed about the mold lntermediate its ends, supporting legs formed, upon said base, cam shaped enlargements formed upon the base at its end portlons, said cam shaped enlargements provided with transverse re cesses in their outer surfaces, and means engaging said annular rib and said cam shaped enlargements for clamping said mold upon said base, said means adapted to engage in said recesses to prevent accidental disconnection thereof with the base.
