NITE STATES PATENT OFFICE.

THOMAS J. HARTON, OF DALLAS, TEXAS.

ICE-CREAM FREEZER.

1 '0 all whom it may concern:

Be it known that I, THOMAS J. HAR'roN, a citizen of the United States, residing at Dallas, in the county of Dallas and State of Texas, have invented certain new and useful Improvements in Ice-Cream Freezers, of which the following is a specification.

My invention relates to new and useful improvements in ice cream freezers, and has for its object to provide a freezer in which the ingredients will be kept in motion by imparting a rocking motion to the freezer, rather than by rotatingthe same, as is the present practice.

A further object is to make the ice-cream receptacle of such a shape that its contents will not be precipitated from the can by the oscillating motion of the freezer.

A still further object is to provide an ice cream freezer which may be operated with less exertion than the present style of freezers, the weight of the freezer furnishing a portion of the motive force.

Finally, the object of the invention is to provide a device of the character described that will be strong, durable, simple and efficient, and comparatively inexpensive to produce.

With these and various other objects in view my invention has relation to certain novel features of construction and operation, an example of which is described in the following specification, and illustrated in the accompanying drawing, wherein;

Figure l is an isometric view of the freezer, and Fig. 2 is a vertical section taken centrally therethrough parallel to its rockers.

Referring now more particularly to the drawings, wherein like numerals of reference designate similar parts in all the figures, the numeral 1 denotes the can or receptacle designed to receive the ingredients of the ice cream. It will be observed that this can increases in size from top to bottom, the purpose of this construction being to deflect the ingredients downwardly when they are thrown against the walls by the rocking motion of the freezer. A further advantage of giving the can this shape lies in placing the greater volume of ingredients in the lower portion of the freezer, where the cold is greatest. A still further advantage of this construction lies in the fact that it Specification of Letters Patent.

brings the center of gravity closer to the base of support, giving the device a more stable equilibrium. The cam 1 is provided with a cover 2 of any suitable design.

The can is set in a water-tight casing or box 3, to which is provided a rounded bottom 4 preferably of sheet metal. At each side of the casing are attached rockers 5, whose arcs are concentric with that of the bottom 4.. The top of the casing 3 is preferably to be made in four parts, the two outer parts 6 being provided with knobs 7 whereby they may be removed to permit of ice being introduced into the box. One of the central parts 8 will be stationary, and the other part 9 fastened in position by screws 10, permitting this part to be removed, if it is desired to withdraw the can from the casing.

A water drainage aperture is closed by the cork 11, and a handle 12 is provided to facilitate carrying the freezer.

Obviously the rockers 5 might be discarded if desired and the device oscillated upon the rounded bottom. The rockers however, lessen the friction and make the operation easier.

The superior simplicity and economy of the described device over the ordinary crank operated freezer is apparent. The several castings necessary to the latter class of freezer are in this one eliminated, and the device may be operated either by foot or hand with a minimum exertion.

The oscillating motion causes the ice to melt more quickly, thus absorbing the heat rapidly from the ice cream.

What I claim, is

In a device of the character described, the combination with a receptacle, increasing in size from top to bottom, of a casing in which said receptacle is centrally mounted, an aperture being provided in the top of said casing through which the receptacle extends, removable closures in the top of said casing, and rockers upholding the casing.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

THOMAS J. I-IARTON.
