IMPROVEMENT IN LAMP-STOVES. Y

Specification forming part of Letters Patent No. 136,063, dated February 16, 1873.

To all whom it may concern;

Be it known that I, FRANZ JANKE, imperial and royal engineer, of Briinn, Moravia, in the Austro-Hungarian Monarchy, have invented certain new and useful Improvements in Inodorous Heating, Cooking, and Lighting Apparatus, of which the following is a specification:

My invention relates to an apparatus for heating, cooking, and lighting with petroleum o1 Hitherto the obnoxious smell and smoke from coal-oil has been the only objection to the general use of petroleum-lamps, and as this oil is the cheapest and safest burningfluid it is of great importance to utilize'it for heating and cooking by obviating the offensive odor and smoke therefrom. This my invention accomplishes; and it consists of a heating and cooking apparatus, in which the chimney projects therein and has certain relations with the apparatus which are essential to its proper action. These are a certain height of chimney; a certain space between its top and the bottom of the culinary vessel, and equal always to the diameter of the chimney-top and with these, equal area of the escape-opening, and of those in the interior partitions with the top of the chimney. This arrangement and relation of parts I have found to produce the desired results of consumin g the gases from the oil so entirely that nothing escapes but inodorons carbon, leaving the kettlebottom unblackened. My improvement also consistsin combining with theheating-chamber of the apparatus an interior wire or net frame, intervening between the bottom of the cooking-vessel and the top of the lamp-chimney, the object whereof is to retain the heat around the kettle, and serve to absorb and burn out the gases; in the construction of the heating part of the apparatus; and in mounting it by socket stems upon a suitable frame; all as will be more fully hereinafter described.

In the accompanying drawing, Figure 1 represents an elevation of an apparatus embracing my invention. Fig. 2 represents a vertical section of the same. Fig. 3 represents a horizontal section at the line X X of Fig. 2; and Figs. 4 and 5, views in perspective, showin g slightly different forms of apparatus.

The cooking and heating apparatus consists of a circular heater, A, flat on top, having a diameter of about twenty-four inches, and its under side B made in the form of a section of a globe. Its top and bottom plates are provided with central openings, the former to receive the cooking-vessel, and the latter to re ceive the upper end of the lamp-chimney G. which, for this purpose, is formed into a neck, D, which surrounds the chimney without touching it, so as to leave as little space as possible to prevent the admission of air. The heating, chamber is divided by a vertical partition, E. into the annular chambers F and G, into the central one of which the cooking-vessel H projects, while the outer one is for the free circulation of the heated air, and communicates at the side or top thereof with the escape-pipe I, and the two chambers communicate with each other by an opening, J, in the interior vertical partition located diametrically opposite the escape-openings K in a partition, L, so that the heat from the chamber G must pass through the openings K to the escape-pipe L. The heating apparatus thus constructed is provided with three tubes, 11, projecting from its under side, which'fit over and upon the upper ends of the frame of the lamp, so that it may easily be removed therefrom. This frame con sists of three stems or branches, b, the lower ends of which form supports for the apparatus and are united to a socket or cup, into which the lamp is fitted securely, while their upper ends are braced by a triangularshaped frame, M.

The lamp is constructed with acircular burner, as I have discovered that a cylindrical wick is best adapted for coal-oil, because it produces a conical flame. Any well-constructed lamp will answer the purpose. The chimney (3, however, must be contracted to form a neck just above the burner, which has the effect of converting a cylindrical into I a conical flame, from three to four inches in height. I have found it necessary that the chimney should be nine and two-thirds inches in height, and the distance between its upper end 0 and the bottom of the culinary vessel in no case less than threequarters of an inch, nor more than an inch and a half, or equal to the diameter of the top of the chimney; and the escape-opening I may be greater, but never of less area than the latter; and the openings J K in the partitionsE L must be of equal area with the escape-opening I and top 0 of the chimney.

In order to concentrate and hold the heat around the bottom of the cooking-pot I secure a wire or skeleton frame, N, to the sides of the partition E, within the central chamber F and between the top 0 of the lamp-chimney and the bottom of the pan or pot without touching either, so as to entirely surround the exposed surface thereof, except just above the chimney, so that the concentrated heat from the chimney will pass. through the central opening (1 in the wire or net frame N, and striking the bottom of the cooking-vessel, will be defiected downward into the wire-net, and thus the latter will become highly heated and conduct the heat up around the sides of the pot and hold it, so as to greatly increase its intensity, and thus act as a consuming diaphragm, burning up and absorbing any gases that may enter the chamber, so that nothing escapes but carbonic gas, free from smell and smoke.

The interior of the heater may be divided into a greater number of chambers, and in proportion to the number of these chambers will be the temperature of the escaping heat. The opening in the top plate may be fitted with insertable rings of varying diameters, and the cooking-vessels provided with flanges so as to fit closely within said opening.

The apparatus may be converted into a heat in g'stove by securing a drum within the central opening of the'top plate; and the wirebasket may be easily replaced when burnt out.

Having described my invention, I claim- 1. The heating and cooking apparatus of a petroleum-lamp having a chimney, O, of a certain specified height, extending into the heatingchamber F, with a space between the bot tom of the latter equal to the diameter of the chimney-top 0, and also equal to the area of the openingsl J K, by which arrangement and relation of these parts the gases and smoke from the lamp are consumed,,as described.

2. The wire netting or basket N, located and arranged within the central chamber F and above the lampchimney, in the manner and for the purpose herein shown and specified.

' 3. The heating apparatus A B, provided with socket-stems a for adjustment upon the branches 1), braced by the frame M, as and for the purpose described.

FRANZ J ANKE.
