DAVID O. FRANKLIN, 0F CARLISLE, INDIANA.

REFRIGERATOR.

f0 all whom it may concern:

Be it known that I, DAVID O. FRANKLIN, a citizen of the United States, and a resident of Carlisle, in the county of Sullivan and State of Indiana, have invented certain new and useful Improvements in Refrigerators, of which the following is a full and complete specification. I

My invention relates to refrigerators of the class that is mounted in wells or cisterns to take advantage of the cool air contained therein; and it has for its object the provision of means by which the air admitted to the cooling chamber is drawn from the region adjacent to the surface'of the water to insure purity and coolness thereof.

My invention will be described in detail 2 hereinafter and illustrated in the accomcistern, showing my improved refrigerator 1 in position therein, the refrigerator-casing being shown in section; Fig. 2, a front View of the refrlgeratlng-chamber; F 1g. 3, and Fig. 4, vertlcal sectional vlews of the chamber looking in opposite directions; Fig. 5, a v

top plan view of the chamber; Fig. 6, a bottom plan view; Fig. 7, a top plan view of the casing extended into the well or cistern; Fig. 8, an edge view of one of the doors, and Fig. 9, a view in perspective of the part of the casing extended into the'well or cistern.

In the drawings similar reference characters indicate corresponding parts throughout all of the views. I

A indicates a well orcistern over which is secured a cover or floor B, having anopening C. S

The casing of my improved refrigerator consists of the casing 1, secured over the opening C and preferably made rectangular in cross-section, and having the ventilating openings 2 in its upper end covered with a screen fabric.

3 indicates the casing extended down into the well from the underside of the cover B in alinement with casing 1, said casing 3 being rectangular at the top and bottom and swelling outwardly in its middle, as shown at 4, where it is circular, its diameter being substantially equal. to the length of the diagonal of the rectangular ends. The purpose of forming casing 3 bulged, as described, is to form a space for the passage of cold air around the refrigerator when Specification of Letters Patent. Patented June 2'7, 1911. Application filed. June 13, 1910.

lowered into the tube, as hereinafter described.

5 indicates braces secured to the lower end of the casing 3 and extended upwardly to engage the side walls of the well or cistern to brace the lower end of the casing to prevent it from swinging when in position.

6 indicates angular vertical guides conneoting opposite corners of the upper and lower ends of the casing 3.

7 indicates a tube secured adjacent to the lower end of casing 3 and extended to the center thereof, 8 a flexible tube secured to tube 7 9 a float having an opening 10 therein covered with screen fabric 11, the free end of flexible tube 8 being extended down into the water and secured in the opening 10 of the float. The tube 8 must be of suflicient length to reach the water in the well or cistern, however low it may fall, and to prevent the tube from floating and endangering the operation of the float and tube I provide a weight 12 that is suspended from a roller 13 that rides on the tube 8.

It will be understood from this construction that the fresh and cooled air will be constantly supplied to the casings 1 and 3, which, as it is warmed, will rise and pass out through the ventilating-openings 2, so that anything that may be placed in said casings will be kept cool by contacting with the air.

14 indicates the refrigerating-chamber, consisting of a rectangular box slidably mounted in casing 1 and on angular guides 6, said box having supporting-arms 15 secured to its top, to which a rope 16 is fastened, and running over pulleys 17 and 18, secured in the top and to the side of the easing 1, respectively, is wound upon a windlass 19, operated by crank-shaft 20 and gearing 21. The box 14 is divided into a num ber of compartments 22, by means of horizontal partitions 23, and each compartment is closed by a separate sliding door 24, mounted in grooved guides 25, to hermetically seal each separate compartment to prevent the odors of the contents of the several compartments from intermingling and spoiling the taste of such articles as butter and milk with the odors of raw and cooked meats and vegetables. I

By lowering the box 14 into casing 3 it will be apparent that it will be chilled by radiation of the heat therefrom, but to more quickly accomplish refrigeration I provide an opening 26 in the bottom of the box and extending into the lowermost compartment 22 and a tube 27 extending from the bottom to and through each of the horizontal partitions 23 and a tube 28 from the top of the box downwardly to and through each partition 23 and a hole 29 in the top and extending into the topmost compartment. As the hole 26 and tubes 27 are on one side of the box and the tubes 28 and hole 29 on the other side thereof, it will be apparent that each compartment is separately ventilated, the air passing into it on one side and, crossing the compartment, passes out through the other side, and its contents are quickly chilled, as well as ventilated.

The lower end of the box 1% is formed with a depending flange 30 to insure a passage under the box for air when the box is in its lowermost position, said flange being formed with a notch 31 to receive tube 7 when lowered.

32 indicates a door on the side of easing 1, admitting to the interior of the casing, so that access may be had to the contents of the box 14, said door being formed with an oiiset 33 to throw the door out of line with the sliding doors 24 to open and close the refrigerating compartments.

Having thus described my invention, what I claim is l. A refrigerator comprising, in combination with a well, a casing seated in and over the well, the part of the casing within the well bulged intermediate of its ends a refrigerating-chamber slidably mounted in said casing, afloat resting on the water in the well, and a tube connecting the float and the lower end of the casing, substantially as shown and described.

2. A refrigerator comprising in combination with a well, a casing seated in and over the well, the part of the casing within the well bulged intermediate of its ends, and a refrigerating chamber slidably mounted in said casing, said casing being provided with ventilating-openings, substantially as shown and described.

3. A refrigerator comprising in combination with a well, a casing seated in and over the well, the part of the casing within the well bulged intermediate of its ends, angular vertical guides secured in the bulged portion of the casing, and a refrigerating-chamber slidably mounted in said casing and in said angular guides, the casing being provided with ventilating-openings, substantially as shown and described.

4:. A refrigerator comprising, in combination with a well, a casing seated in and over the well, a refrigerating-elmmber slidably mounted in said casing, a float resting on the water in the well, a tube connecting the float and the lower end of the casing and a weight normally mounted on the tube, substantially as shown and described.

5. A refrigerator comprising, in combination with a well, a casing seated over the well, a casing extended into the well, the last-mentioned casing being rectangular at its upper and lower ends and its middle bulged and circular in section, angular guides secured in said bulged casing, and a refrigerating-box slidably mounted in said casings and engaging said angular guides, substantially as shown and described.

6. A cooling device for well-refrigerators comprising in combination with a casing extended into the well, a tube secured to the lower end of the casing, a float secured to the said tube, a roller mounted on said tube, and a weight suspended from said roller, substantially as shown and described.

In witness whereof, I have hereunto set my hand in presence of two subscribing witnesses.

DAVID O. FRANKLIN.
