REFRIG ERATO R.

SPECIFICATION forming part of Letters Patent No. 570,426, dated October 27, 1896. Application filed February 26, 1896. Serial No. 580,863. (No model.)

T0 a/,ZZ whom t may concer/t:

Beit known that I, EDWARD H. GIESY, a citizen of the United States, and a resident of the village of Vyomi-ng, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Refri gerators, of wh-ich the following is a specif1- cation.

The several features of my invention and the various advantages resulting from their use, conjointly or otherwise, will be apparent from the following description and claims.

In the accompanying drawings, making a part of this specification, and in which similar letters indicate corresponding parts, Figure l, Sheet l, is a view in perspective of the front and one end of a refrigerator embodying my invention, the doorsof the two left-hand provision-compartments and the door of the ice-chest being open. Fig. 2, Sheet 2, is a vertical central section from end to; end, taken in the plane of the dotted line 2 2 of Fig. Fig. 3, Sheet 2, is a horizontal section taken in the plane of the dotted line 3 3 of Fig. 2. Fig. 4, Sheet 2, is a vertical section from front to rear, taken in the plane of the dotted line 4l 4. of Fig. 2, and looking at that face of the section which faces toward the left hand of Fig. 2. Fig. 5, Sheet 2, is a vertical section from front to rear, taken in the plane of the dotted line 5 5 of Fig. 2, and looking at that face of the section which faces toward the right hand of Fig. 2. Fig. 6, Sheet l, is a view in perspective of the refrigerator, showing the upper and lower divisions separated.

The several features of my invention are applicable to a refrigerator in which the entire frame is integral, and also to one made in sections.

In the drawings, Figs. l, 2, and 6, I have shown the refrigerator as made in sections, premising that a description of theprinciple ofconstruction of my invention and the oper'- ation thereof as applied to a sectional refrigerator will be understood'` when applied to a .refrigerator whose frame lis entire, as indi cated in Figs. 4. and 5. There are four compartments, twoin` the upper and two* in the lower halfor section. Of these'compartm'ents one G is for the rece tion and retention of the ice and the other three, respectively indicated by the letters II, I, and J, are provisionchambers to receive and hold the articles of food to be kept good, fresh, and sweet. Each compartment is provided with a door W. i That of the ice-compartment is preferably at 4the topv of the chamber, as shown, but it may be at the front thereof. The doors of the pInvision-compartments are at the front of ltheir respective compartments, and are duly `hinged and provided with suitable latches for catching the door when shut and holding it tightly to place until unlatched.

dulypacked with a substance which is a nonconductor of heat. In the drawings I have shown the sides or ends and the back and the `front of the refrigerator, including the doors, preferably (as is customary) packed with a` liningV or packing X, which does not conduct heat, and for this reason I am accustomed to employ mineral wool, as one of the best, if not the best, of packings.

A indicates the lower or basal section of the refrigerator, and B the upper one. Each section is provided with the usual back O and ends D D and front E, and the upper section B has the top B2 and the lower sectionA has the bottom A2.

The ice-compartment G is located substantially asset forth. It is zinc lined and is provided with a suitable rack or shelf G3, preferably made of indurated ber. On this rack thel iceV rests.

In the bottom or iioor G2 of the ice-coinpartment are two openings. One, K, conducts all water from the chamber to the dri p-pipe L, and the latter conducts the water down and away from the refrigerator. A vessel is usually placed beneath this drip-pipe L and reoei-ves the water therefrom. The preferred location of this drip-pipe L is between the walls of the two lower compartments II and I in a small compartment F formed between said walls and the front and rear of the refrigerator.

To enable the sections A and Bto be readily separated and without injuring the drip-pipe, I divide this pipe and furnish the upper end ,ofthe'lower part with an enlarged or funnelshaped aperture L2, or equivalent device, into' The inclosing shell of the refrigerator isl IOO which the lower end of the upper part of the pipe enters or registers with when the sections A and B of the refrigerator are together, substantially as shown.

An opening M for the passage of cold air .from ice-compartment G downward toward compartment H is present in the bottom of said compartment G and is provided with a surrounding guard-Wall M2, whereby the water collecting on the iioor G2 is prevented from getting to the passage M and running down into the chamber H below.

Each of the provision-chambers1I, I, and J is provided with its own lining, consisting of a stoneware crock open at both ends-viz., open toward the front and the rear of the refrigerator. Each crock has preferablya ledge C L at the rear upper end and at the rear lower end portion. These crocks are of stoneware, vitriied and glazed, resisting the action of the acids or alkalies of the provisions placed in the compartments, and are at all times readily washed and cleaned. These crocks are usually upheld beneath by cleats T crossing the bottom of the crock at front and rear, sub stantially as shown.

rlhe cold air from the ice-compartment Gis compelled to pass down through the opening M and between the floor G2 of the ice-compartment and the upper surface of the roof or top of the crock H C of compartment H, and to pass down around the end or ends of the crock and into the room or space within the crock H C. To enable and compel the current of air to take this direction, I provide a space H S between the end of the upper part of the crock and the adjacent end of the compartment II. In case the air is to pass only at the front end of the crock, the space H S is there; if only at the rear end of the crock, the space H S is there; and there is such a space at both ends of the crock when the air is to pass down at both ends.

A novel and convenient mode of shutting the passage at either end of the crock I-I C is as follows: A cleat is put close to the said end of the crock and in the space between the top of the crock and the bottom of the ice-compartment, thus there shutting that passageway from the space between the bottom of the ice-compartment and the top of the crock into the adjacent down passage Il S at the end of the crock.

In the preferred construction the air passes down at both front and rear ends of the crock. XVhen the air has entered the room inclosed by crock H C, it cools this compartment and the articles therein, and then passes to compartment I. This it does by passing through an opening H C O in the side of crock H C,

as shown, thence through an opening I-I C on the wall of the compartment II. After passing through this opening, the air crosses the aperture or chamber F, in which the drippipe L is located, and thence passes through opening I O of compartment I, and thence through the opening I C O in the adjacent side of crock I C of compartment I, and thence into compartment I. Therein this air cools the articles of food in this compartment and then passes up past the front and rear ends of the crock I C through the openings I S7 which I provide between the walls of the refrigerator and the front and rear ends of the top of the crock I C, and through openings I S2 inthe roof I2 of chamber I, and thence into chamber J through openings J S F in the lower portion of that chamber, thus pass ing the ends of the bottom of the crock J C of chamber J -viz., through the openings J S between the crock J C and the walls of the refrigeratorand thence the air enters into compartment J and circulates through it and then passes out and up through the openings J S2 between the ends of the crock J C and the Walls of the refrigerator,- and from there passes up over and upon the roof or top J C R of the crock J and assists in cooling said roof, and thence passes over the vertical partition H J P and beneath the top of the refrigerator through opening H J S into the compartment G. Here the air is cooled and again traverses the refrigerator in the manner heretofore described.

Special attention is called to the fact that the cold air passing from the ice-chamber G comes immediately into direct contact with the top crock H, and the latter, being a good conductor of heat, at once becomes chilled through contact with the cold air. This crock thus has the advantage of being cooled at outside as well as having its interior cooled by the cold air subsequently entering the said interior.

In case end cleats are substituted for the inner side walls to hold the crooks laterally in place, the holes H C and I O will be omitted, being merged in the space F.

The opening M may be located over the end space at front or rear of crock, as case may be; but in such event the advantages of the first contact of the cold air of the ice-compartment with the top of the crock H C will be lost.

llyhile I employ the wor( stoneware in this description, I desire it to be understood that any vitriied material or material covered with a vitrified glaze, or glaze formed on the article by heat, is the equivalent of the stoneware, and is intended to be covered by that term in the specification and claims.

There is a great advantage in the passages present, both in front of and behind compartment J, for the reason that they permit the air to enter the crock and pass through it to the rear, and vice versa, and also pass directly up through both front and rear spaces, thus giving or securing an unretarded circulation of the air, resulting in a low temperature because of the freer circulation and the more frequent passing of the air over the ice.

Vhat I claim as new and of my invention, and desire to secure by Letters Patent, is-

1. In a refrigerator, the combination of the IOO IIO

i'our compartments, two below and two above, and of which latter one is an icc-compartment, and the crooks, open at each end (otherwise solid) and respectively located in each provision-compartment, the ice-compartment having the air-outlet in its bottom and a space being present between the ice-compartment and the roof of the crock of the compartment below, and space being present at one end of the last-named crock, communicating with the space above the crock, substantially as and for the purposes specified.
