COOKING APPARATUS AND REFIGERATOR.

Specication forming part of Letters Patent No. 59,1141, dated November 6, 1866.

To all whom it may vconcern Be it known that we. JOSEF NEUBURG and IGNAZ NEUBURG, both ofthe city, county, and State of New York, have invented a new and Improved CookingApparatus; and we do hereby declare that the following is a full, clear and exact description of the same, reference being had to the accompanying drawings, making a part of this specification, in which- Figure l is a vertical transverse section of the apparatus. Fig. 2 is a plan or top View of the same with the cover removed. I

Similar letters of reference indicate corresponding parts in both figures.

This invention is designed not only for cooking or stewing meat and vegetables, but also, when desired, for use as a refrigerator to preserve the same or other like perishable substances from the injurious effects of a warm atmosphere; and it consists in a novel construction of an apparatus whereby the desired object is accomplished.

To enable others to understand the construction and operation of our invention, we will proceed to describe it with reference to the drawings.

The casing or outer portions of the apparatus is composed of two sheet-metal vessels or cases, a and b, which are placed one withinl the other, with a space between them, which is iilled with pasteboard or other suitable nonconducting material, as shown at c in Fig. l. When pasteboard is employed it is formed into the shape of cases or boxes closed at one end, and of a shape corresponding to the inner and 'outer metallic cases, a b. These pasteboard cases are placed one inside the other, and are iitted snugly into the space between the aforesaid inner and outer metallic cases, a b, thus constituting` a non-conducting layer around the sides and bottom of the apparatus, to prevent the transmission of heat through the said sides and bottom. It should be mentioned that the bottom of the layer of pasteboard just mentioned is prevented from coming quite in contact with the bottom of the outer case, b, by means of small supporting blocks or studs d, so that a small space, e, is left between the said pasteboard and the aforesaid bottom of the outer metallic case, b, the object of which will presently appear.

Attached by any suitable means to the under surface of the bottom of the outer metallic case, b, at one side thereof and removable therefrom, is a small panor receptacle, j'. The interior of this pan fcommunicates with the space e by means of a small hole or opening, g, formed in the bottom of the case b, as shown in Fig.

1. The upper ends of the inner and outer mey tallic cases, a b, are connected together by an annular plate, h, which is somewhat narrower than the space between the said cases a b. The inner edge of this annular plate h is soldered continuously to the adjacent edge of the said upper end of the inner case, a, while the outer edge thereof is attached to the upper end of the outer case, b, by soldering at intervals, so that slots or openings lfare left between the outer edge of the said annular plate and the outer metallic case, b, as shown more clearly in Fig. 2, the said openings communicating with the space iilled with pasteboard c, between the inner and outer cases, a b, as just set forth.

The annular plate h is made inclined on its upper surface, with its outer edge lower than its inner edge, so that an annular gutter is formed just within the upper end of the outer case, b, as shown more clearly at m in Fig. 1. This outer portion, a b c, may be supported by any desired number of legs k, or by any other suitable means.

A represents the cover of the apparatus, which is made double bymeans of an internal plate, n, the space between the outer portion .of the said cover and its inner plate, n, being iilled with pasteboard fr, which is iirst out into the form of rings or annular plates and snugly itted into the said space, as shown in Fig. 1.

The diameter ofthe inner plate, u, is not quite as great as that of the rim of the cover A, so that a narrow opening is left between them, which communicates with. the pasteboard filling r, as shown at s in Fig. l, the edges of the plate n being soldered at intervals to the said rim, so that it is rmly iixed in place. The cover A is fitted upon the casing a b c with sufficient closeness to prevent the escape of vaporthrough the joint, and may be attached thereto by a hinge, t, at one side and a hasp,

fa, at the other.

B represents a central vessel, in which the articles to be cooked or preserved are placed, and which is made of sheet metal. This ce'ntral vessel, B, rests on the bottom of the casing a b o, but is of considerably less diameter than the said casing, so that an annular chaming beingfpacked with the non-conducting pasteboard illing r prevents the outward radiation of heat from the said hot or boiling water, at the same time that the sheet metal, of which the sides of the inner vessel, B, are formed, permits the heat from the hot water to be radiated freelyr through the said sheetmetal sides into the said inner vessel, B, where it slowly cooks or stews the meat or vegetables placed therein. Thus, for instance, beef maybe steWed in about three hours, and potatoes in an hour and a half. rI he vapors from the hot water pass upward, and a minute portion passes through the openingss into the interior of the cover A, while the greater part is condensed upon the under side of the inner plate, n, of the said cover, and runs into the gutter m, and thence, through the openings i, down through the pasteboard lling r of the casing a. b c, into the space e,

(the object of the said space being to prevent the complete saturationof the lower portion of the pasteboard filling 'r,) from which it passes through the opening g into the pan f, from which it may be poured or emptied out when desired. By this means the Waste of heat from the evaporation ofthe 'Water is effectually prevented.

When it is desired to use the apparatus as a refrigerator the annular chamber C is left empty, and the meat or vegetables are placed in the central or innermost vessel, B, the cover A being iitted closely in its place, as hereinbefore fully explained. The non-conducting nature of the outer casing, a b c, and of the cover A prevent the passage inward of heat from the atmosphere, so that the contents of the central vessel, B, are kept in a cool condition in the saine manner as an ordinary refrigerator. p

What We claimas new, and desire to secure by Letters Patent, is-

The non-conducting double Casin g a b c, hav-v ing an annular gutter, m, openings i, opening g, and pan f, and furnished with the non-conducting cover A, in combination with the central vessel, B, the whole constructed and arranged substantially as herein set forth,for the purpose specified.
