REFRIGERATOR.

SPECIFICATION forming part of Letters Patent No. 467,886, dated January 26, 1892.

l Application filed May 20, 1891. Serial No. 393,482. (No model.)

To d l'wwm it may concern.-

Be 1t known that I, DANIEL BARCKDALL, of Indianapolls, county of Marion, and State of Indiana, have invented certain new and useful Improvements in Refrigerators; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, in which like figures refer to like parts.

My invention relates to improvements in refrigerating-chests and will be understood from the following description.

In the drawings, Figure l is a vertical section on the line a: a', Fig. 2. Fig. 2 is a vertical section on the line y y, Fig. l. Fig. 3 is a horizontal section on the line ze, Fig. l.

In detail, l is the outside of the chest, formed of wood.

2 is a layer of mineral wool or any other non-conducting material.

3 is a lining of metal.

4 is an air-space.

5 is the wall of an inner metal casing, which is supported by feet 6 above the metal hoor of the main chest itself.

7 is a Water-space, and 8 is the wall of a second inner casing, which is supported by feet 9, which rest upon the 4bottom floor of the metal casing 5.

l0 is a metal box, on whose sides are hooks 11, hooking over the upper edge of the walls of the metal casing 8 on three sides, as shown in Fig. 3, whereby the metal box l0 is suspended.

2 are tubes which pass through the box 10 from side to side, as shown in Figs. l and 2, forming cold-air ducts, and the box l0 is filled partly with water and the remainder of the way with broken ice, which is preferably salted to increase the cold.

13 is an overflow-pipe leading from the box l0, so that as the water increases by the melting of the ice it will run out and fill the waterspace 7 between the metal casings 5 and 6.

14.- is a pipe leading from the ice-box lO downward to within a short distance of the iioor of the metal casing 8, so that by opening the faucet connected to the pipe 14: a small amount of water may be discharged into the casing S upon the bottom thereof to assist in keeping the latter cool.

19 are vertical projecting strips connected to the bottom of the casin g S, upon which may rest cans or receptacles containing material Vto be kept cool.

l5 is a drain-pipe, with a faucet attached, connected with the bottom of the inner casing 8, by which the water in the latter may be drawn off, if desired.

16 is an outlet-pipe connected near the top 6o and to the water-space on one side and below the line of the overiiow 13 in the box l0, as shown in Figs. 2 and 3, by which the water may overiiow and is carried by this pipe down through the bottom of the refrigerator-chest.

17 is a projecting recessed shelf secured inside the refrigeratiug-casing just below the cover, forming a hood over the air and water i spaces 4t and 7 and aids in 4holding the cold air in them, and its top affords a place for 7o standing bottles.

1S is the cover which closes the chest, the latter being only open at the top.

My device therefore comprises au outer chest with two interior casings, a cold-air space 7 5 between the outer part and the vfirst metal casing, a water-space between the rst and second metal casings, and a third metal casing or box for holding the ice, containing airtubes still within. A current of air freely 8o circulates through the tubes and the various parts of the interior of the casing, and the water contained in the lining in connection with the air is also cooled by the ice and salt and keeps the whole interior cold at all times 8 5 and elfects a great saving of ice. The large opening in the inner casing 8 is for receiving the articles to be cooled, and they rest directly upon the projections 19, and below this is the water, as before mentioned. It is not neces- 9o sary in all cases to allow the water to escape into the interior of the chest 8; but it sometimes may be advantageous to do so, and when the water is drawn 0E from the waterspace it may be poured back again upon the ice in the box 10 and again cooled, thus et fecting a saving of time and handling of water and utilizing all the cold that it has received while in the interior of the chest.

That I claim as my'invention, and desire Ioo to secure by Letters Patent, is the following:

l. A refrigerator comprising an outer casing of wood lined with metal, an inner metal casing supported above the metal lining of theonter easing, an air-space between such easings, a second inner metal Casin g supported upon feet above the floor of the first metal easing, a waterlspaee between such metal cas- 5 ings, an overflow-pipe tapping the water-space and leading outside the refrigerator, a inetal box for ice suspended from the wall of the inner metal easing and having air-pipes through the same below the ice-box, an overiiow lead- /m/ing from the ice-box to the water-space between the metal easings, and a eover closing the refrigerator at the top, all combined substantially as shown and described. v

2. A refrigerator comprising an outer eas- 15"*ing lined with metal and a packing of inineral wool or other non-conducting material between, an inner easing formed of inetal or other suitable material, an air-space between the outer Wall of sneh easing and the metal 2o lining of the outside easing, a second casing inside the first easing, with a water-space between, an ice-box suspended from the wall of the innermost easing, an overiiow Connected therewith leading to the water-space, each 25 easing supported above the other by legs or feet, an overflow from the ice-box to the iioor of the innermost easing, a pipe leading from such floor outside the refrigerator anda top for closing the refrigerator, and shelves above the ice-box for supporting bottlesand acting as a 3o cover for the air and water spaces of the casings below, all combined substantially as shown and described.

3. A refrigerator comprising an outer shell or easing. an inner casing with an air-space 3 5 between it and the outer Casin g, a second inner easing having a water-space between it and the first inner easing, an ice-box Suspended from the wall of the second inner easing, an outlet leading from the ice-box to the 4o water-spaee,andan overflow-pipe leadingfrom the water-spaceV outside the refrigerator, in

combination with a cover closing the top of the chest, and a shelf below sneh cover and above the ice-box for supporting similar articles, 45
