COOKING UTENSIL.
SPECIFICATION forming part of Letters Patent No. 397,847, dated February 12, 1889. Application filed January 16, 1889. Serial No. 296,499. (No model.)
To (LZZ whom it may concern.-
3e it known that 1, JOHN H. FREDERICKS,a citizen of the United States, residing at Lock Haven, in the county of Clinton, State of Penn- 5 sylvania, have invented certain new and useful Improvements in Cooking Utensils; and I hereby deel are the following to be a full, clear, and exact description of the same.
My invention relates to an improvement in to cooking utensils, and has for its ultimate ob ject the protection of the contents of the utensil during the process of cooking from scorching by reason of the undue application of heat, and the immediate object is to provide a cooking utensil having these characteristics of a more economical and desirable construction than has heretofore been found practicable. It has been suggested that the scorching of the contents of the cooking utensil during the process of cooking can be prevented by providing the article with a double bottom and interposing therein a non-combustible materialsuch as magnesium powder, &c., or asbestus fiber. In all constructions with which I am acquainted,however, it has been deemed necessary to interpose the non-combustible material loosely, requiring special manipulation of a laborious and expensive character in the construction of the article. Thus, when the powder was employed, the lower bottom was first filled, then applied to the upper bottom or lower sides of the ware present no protection against the scorching heat. In the second place, the delay in the process of manufacturing the article necessary to permit the interposition of loose non-combustible material is so great as to involve a material increase in the cost of manufacture. I overcome these difficulties by the construction and method hereinafter described, although I wish it understood that in this specification I mean duced by other methods than the one hereinafter set forth.
My invention consists in a culinary vessel provided with a double bottom and having interposed between the bottoms a sheet of non-combustible material secured at its circumferential edges between the circumferential edges of the double bottom and the vessel.
My invention further consists in a vessel of this character having a double bottom and double sides for a short distance above the bottom, presenting a contin uous chamber and having interposed between said double bottoms and sides a single sheet of incombustible material secured at its circumferential edge between the upper edge of the outer double side and the vessel.
In the drawings, Figure 1 is a vertical sectional view of a cooking utensil made in accordance with my improvement, in which the incombustible material is applied in a single sheet to the bottom only. Fig. 2 is a similar view showing the incombustible material applied to the bottom and lower sides.
A represents the body of the vessel, having an integral bottom, D.
Bis the lower bottom, which may be extended to produce an outer or double side, as shown in Fig; 2.
O represents a sheet of asbestus or similar incombustible material, which may or may not be provided with perforations, in the usual manner. The bottom B may be secured to the vessel A either by riveting or soldering the same; but, as shown in the drawings, it is preferably secured by spinning.
In producing the article a sheet of asbestos of suitable size is stamped to the proper shape at the same time that the other parts of the vessel-to wit, the body A and lower bottom, Bare formed, and the parts thereupon adjusted together and riveted, brazed, spun, or
protecting medium is at all times firmly secured in place and the increased cost of interposing the protecting medium is reduced to the minimum.
secured upon the vessel by spinning, the inl \Yhen the lower bottom is terposed material is secured at its edges dur- 1 cu red at its eirmim'ferent ial edge bet-ween the ing the same spinning operation that secures the double bottom to the vessel.
What I claim as new, and desire to secure by Letters Patent, is t 1. As a new article of manufacture, a culii nary Vessel having a double bottom and haw ing an interposed sheet of non-eomlnistible 1.
material seeured at; its eireuml'erential edge 1 between the lower bottom and the vessel, as described.
2. As a new artiele olj' manu'laeture, a culinary vessel provided with the double bottom and double lower sides and having an inter posed sheet of non-cmnlmsiible nmterial sedouble side and the vessel and covering the bottom and part of the sides of the latter, substantially as described.
