I SECIFIQATION forming part of R'eissned Letters Patent No. 9,786, dated July 5, 1881.

' Original No. 77,098, dated April 2l, ISGS. Application for reissue iiled June 7', 1831. I

To all whom it may concern;

Be it known that I, HENRY A. ROBERTS, of Detroit, in the county of rayne and IState of Michigan, have invented a new and useful Iniprove'xnent in Refrigerators, of which the following is a speciiication.

In the drawings, Figure l is a vertical sec- Figs. 2 and.3 are horizontal sections through the ice-box, and Eig. 4 is a top View of one ofthe shelves. l. 1

My invention consists, iiist, in constructing a refrigerator in two or more sections, fitting that sections can be readily added or taken away to increase or diminish the capacity of the refrigerator; second, in an ice-box for are frigerator,which of itselfis perfectly airtight, removable, and adjustable at pleasure, having a vertical llue or a series of vertical lines open at the top and bottom, relatively to an intersectin g horizontal flue havin g discharging-orilices for both circulating currents of air and the products of atmospheric condensation, when the same is arranged with a `frigorilic chamber, producing results of refrigeration by means of internal continuous Circulation of currents of air, the outer walls of which are perforated and covered with fibrous or evaporating substances; third, in placing in la refri gerator an air-tight icebox havin gan opening in its top provided with a tight-fitting cov-' er, for the introduction of ice, and having one or more vertical ilnes running through said ice-box', fourth, in placing radial conductors in such flue or tlues, to increase the coolingsurface in such ilue or fines, and thereby increase the downward current of air through such ue or lues.

A, B, and C arc three sections, which compose ythe body of this refrigerator, showing at a glance that it maybe made and used in'one,

two, or more parts, as desirable.

a a' are the outer and inner walls, made of sheet metal or 'some `other suitable material.

a2 are the ring-Ilangcs, by which the outer and inner walls arc closed air-tight lby means of bolts, soldering, oil-'otherwise liernietically scaled, to render the space air-tight.

a3 is the bottom, constructed with two tliicle nesses, impervious to air. a4 are doors fitted closely to their respective openings, constructed hollow, of sheet nietal or other suitable l material, and hungV in theusual way.

a5 is a cover, also constructed hol-low, of 55 metal or other suitable material, and so that it will t the upper end of either'of the scctions. Through the center ot' this covenis proy i p vided a vent orificeA or tube, c'. rlhe only ob ject of this vent-tube is to ventilate the box or 6o receptacle when the freezing material is exhausted. f. i f Upon the inner walls of the sections are arranged rollers or brackets d, upon which the' -fraines or shelves d' arc supported, and rotate 65 as desired, either to the right or left, in order to bring any one of the receptacles placed thereon directly before the door. 2

. D is an ice-box arranged in the upper portion of the refrigerator, composed wholly of 7o inetal or other suitabley material, the bodyh ot' which is perforated or tight and united toatigbt botto1n,i, slightly conical in shape.

, It' Ic' are lines Which pass through the top i and the bottomrz" of ice-box D, in which fines are 7 5 radial partitions i2, to increase the cooling` and condensing surface.

, m is a cover which closes the top or open ing of the ice-box, thereby rendering it airtight. When ice-boxv D has perforated sides 8o it is covered with a fibrous material, n, for the n purposeof cooling the air by internal continnous circulation without coming in contact 1 with the ice.`

o is a discharge-pipe. p is a iluid-cup, which receives'the drip from the lower edge of the fibrous' material n, and

'discharges the surplus water through pipe o',

near the upper edge of the cup, into discharge pipe'o", and when the sides of ice-box D are g'o tight the drip is led by a suitable pipe or discharge oriiice into cup l p and discharged through pipes o and o.

The operation of this refrigerator is substan tia-ily as follows: The icebox D being filled with ice, and the openingin the top closed by y cover in., the ice cools the `air within the ues k .7t,and this air falls into the refrigerator, displacing a portion of the air in the refrigeraten'.V As the refrigerator is air-tight, and the interior has no communication with the outside air, the air thus displaced rises around iee'box D to the 2 i :mso

top of the refrigerator, passes over the top of ice-box D into the fines 7c it', and is again cooled and discharged downward through the fines.

When the sides of ice-box D are perforated and covered with iibrous material a the drip from the melting ice We ts the ilorous material, thereby preventing' the air in the refrigerator from coming in contact with the iee in iee-box D, and the upward current of air around ieehox D causes this moisture to evaporate, and thus adds to the cooling effect produced.

It will thus be seen that the air in the refrigerator is compelled to circulate down through the lues 7c 7c and upward around the ice-hex D, Without the admission of any external air.

- What claim as my invention, and desire to secure by Letters Patent,isp l. A refrigerator constructed of metal or other suitable materiahaot' two vor more sections, suhstantiallyas and for the purposesset forth.

2. The ice-box D, having close hottoni,perforated sides covered with iihrous material, whereby the hex is rendered air-tight, sun stantiaily and for the purposes set forth.

3. In a? refrigerator, a tight ice-box with an opening in the top thereof for filling the/salue With ice, and having a tight-iitting cover for said opening, provided with one or more Ver tieal rines through said ice-box, as and for the purposes herein set forth.

4. The airtight ice-box D, constructed, as hercinbei'ore described, With or without perforated sides and placed in a refrigerator, so that theair in the refrigerator can enter vertical Hue or ues ruiming through said ieeboX at the upper end of such fine oriiues, and pass downward through such flue or lues, and be discharged through a horizontal intersecting ilueouthe bottoni of said iee-hox directlyinto the refrigerator.

5. An ieebox, as above deseribed,pro\f'ided with a iue or series of tlues, With or Without radial divisions, for the circulation and con densation of air, vsubstantiallyas described.

6. An ice-box, as above described, provided with a ldue or series of fines, with or without perforated sides or evaporatingisurfaegsub stantially as described.
