COMBINED ICE-CREAM FREEZER AND REFRIGERATOR.

Application filed July 9,

To all whom it may concern:

Be it known that I, IVILLIAM H. SARGENT, a citizen of the United States, residing in the city of St. Louis and State of Missouri, have invented a new and useful Combined Ice- Cream Freezer and Refrigerator, of which the following is a specification.

This invention relates to a combined ice cream freezer and refrigerator.

An object of the invention is to provide a combined freezer and refrigerator comprising a compartment for the ice and for the receptacle containing the material to be frozen, and a separate refrigerator compartment for other articles arranged to be cooled by the cold air passing thereinto from the inclosed space surrounding the freezing compartment, so that the same quantity of ice serving the freezer also serves the refrigerator. I

Another object of the invention s to provide an improved article of the character mentioned having an inclosed space surrounding the freezer compartment and passages from said space communicating with the refrigeratorcompartment, whereby the cold air produced in said space by the ice within the freezer compartment is free to pass into the refrigerator, in combination with means for opening and closing said passages to control the quantity of cold air that may enter the refrigerator.

Another object of the invention is to provide an article of the character mentioned including a freezer compartment adapted to receive the receptacle containing the material to be frozen. surrounded by the ice placed within the freezer compartment, and means held in place by the closure or cover of the freezer compartment for retaining the receptacle therein in proper position and to prevent the receptacle from rising upon the water or ice inthe freezer.

Other objects to be attained by my invention will appear from the following description, without the necessity of specific mention thereof.

In the accompanying drawings, in which I have illustrated a preferred embodiment of the invention,

Figure 1 is a vertical longitudinal sectional view of my improved combined freezer and refrigerator, taken approximately on the line 1-1 of Fig. 2.

Bpecification of Letters ZPatent.

Patented Nov. 19, 1918-.

1917. Serial No. 179,323.

Fig. 2 is a horizontal sectional view taken on the line 2-2 of Fig. 1.

Fig. 3 is a plan view illustrating the top of one of the freezer compartments.

As illustrated the structure includes four corner posts 1 to which are secured the outer walls 2 and the inner walls 3 spaced therefrom. The walls 2 and 3 at the front do notextend entirely from end to end, but are formed to leave an opening which is closed by a door 4 supported on hinges 5 at one side and controlled by an appropriate latch device 6 at the other side, whereby the door may be held in closed position, as illustrated in Fig. 2. The entire space between the outer and inner walls is filled by appropriate insulating or non-conducting material 7, such for instance as ground cork, or material of that character, thus confining all ofthe cold air produced within the device and preventing the exterior heat from affecting the contents.

The bottom of the device includes a lower wall. 8' and an inner upper wall 9 spaced therefrom, the space between said upper and lowerwalls also being filled with a quantity of material 10, similar to the material 7 and serving a like purpose.

The interior of the inclosure formed as above described is divided into a number of separate compartments. In the embodiment illustrated the interior is divided into three compartments, one of which is at each galvanized iron, or other material, as desired. Each of the compartments 11 is supported upon a series of spaced strips 12 secured to the upper wall 9 of the bottom, and provided with numerous notches or openings 13 so that the air may freely pass and circulate between all of the spaces under the bottoms of the compartments 11. The side walls of the compartments 11 are braced and supported in position by-numerous spaced upright strips 14; attached to theinner walls- 8 and provided with numerous openings or passages 15 through which the air is free to circulate entirely around the compartments 11.

The inner side walls of the compartments 11 are also supported and braced in position by a transverse series of spaced uprights 16 having numerous openings or passages 17 enabling the air to circulate freely through all of the spaces and thence int-o the refrigerator chamber located between the two series of uprights 16. The lower ends of each series of uprights 16 are held in position by a transverse member 18 and the upper ends of said uprights are held in position by a similar transverse member 19.

The compartments 11 are adapted to contain the ice and the container for the material to be frozen. As shown, there is a container 20 located centrally in each of the compartments 11, resting upon the bottom of said compartments so that the ice placed or packed within said compartments will entirely surround said containers and freeze the contents thereof.

The top wall 21 of the combined freezer and refrigerator is provided with openings commensurate with the upper ends of the compartments 11, and said openings are provided with closures or lids 22 which, when placed in position, form practically hermetic closures for the ice compartments. Each closure 22 is formed with a central opening therethrough in alinement with the upper end of the corresponding container 20 through which access may be had to thecontents of said containers. The openings through the closures 22 are closed by removable covers 23 having depending portions seating in the openings, and annular portions resting upon the closures 22, as illustrated in Fig. 1. The closures 22 are secured in place by movable retaining clips 2 1 which may be drawn to position to permit removal of the closures in order to afford access to the ice compartments.

The closures 22 are shouldered as indicatecl at 25 in order to provide abutments for the upperends of the removable rings 26. The rings 26, in the embodiment illustrated, encircle the upper ends of the containers 20 and may be supported thereby by any appropriate conformation, as by providing shoulders 27 on the rings constituting abu'tments for the upper ends of the containers 20. As a result of this construction the containers 20 will be retained centrally in their respective compartments and will be prevented from floating or rising as the .ice melts in the ice receptacles.

From the foregoing description and by reference to the drawings it will be apparent that the air in the spaces around the ice compartments will be chilled'or cooled and that I the Coldair from said spaces may freely pass into the intermediate refrigerator compartment. As illustrated the refrigerator compartment contains a number of shelves or horizontal partitions 2 8, preferably com posed of spaced strips securely supported at their ends, so that the articles placed thereon will be upheld, and the cold air will be free to circulate into contact with and between the articles stored in the refrigerator.

I have found in practice that the temperature of the refrigerator compartment will be reduced to or below freezing point when said compartment is left closed for a period of several hours. It is therefore desirable in some instances to regulate the temperature by preventing the circulation of the cold air from the inclosed spaces around theice compartments into direct contact with the articles stored in the refrigerator. For thus regulating the temperature and the quantity of cold air which may enter the refrigerator, or for shutting off the circulation of the cold air entirely, at the option of the user, I have provided a manipulative shutter or closure at each side of the refrigerator compartment, whereby the openings from the cold air spaces may be reduced or entirely closed. Each shutter illustrated includes a number of vertical strips 29 of a width approximately equal to the spaces between the uprights 16, so that when said strips are moved opposite said spaces, the spaces will be closed, and when said strips are moved opposite the uprights the spaces will be open. The lower ends of the strips are attached to a transverse frame member 30 and the upper ends are attached to a similar transverse frame member 31. The frame members 30 and 31 are operatively mounted in grooves or channels formed in the strips 18 or 19, so that by moving the shutter thus constructed in one direction the passages in the refrigerator compartment may be closed, as illustrated at the left in Fig. 2, or by positioning the shutter so that the strips are opposite the uprights 16 the passages may be left open to permit free circulation of the cold air into the refrigerator compartment. Each of the shutters may be provided with a manually engageable handle or knob 32, whereby they may be conveniently moved from one position to another.

For conveniently withdrawing any accumulation of water from the ice compartments, I provide drain pipes 33 having manipulative valves 34 of any well known type. These are preferably located near the bottoms of the ice compartments for'well understood reasons.

It will be understood that any material may be employed in the construction of this device, and that it is not necessary to construct the ice compartments of metal, al-

though in many cases that is preferable. There may be other variations; in the construction and arrangement of this device without departure from the principle of the invention.
