IMPROVEMENT IN PETROLEUM-STOVES. a

Specification forming part of Letters Patent No. 187,17 l, date-d February 6, 1877; application filed September 22, 1876.

To all lwhom it may concern:

Be it known that we, OTTO PE'rscH and HERRMANN SGHIEBLER, both of the city, county, and State of New York, have invented an Improvement in Petroleum-Stoves, of which the following is a specication:

This invention relates to that class of petroleum-stoves in which the flame of the burner is to a greater or less extent utilized in heating the contents of a boiler or water-reservoir surrounding the burners, but which, as hith-` erto constructed, have depended for their utility upon the conduction of heat from the wicktubes of the burners, a plan imperfect in its results, and bringing the reservoir into such close relation with the wick-tubes as to render the use of the stoves for ordinary cooking and other purposes extremely diicult.

The object of our invention is to provide a petroleum-stove which, while capable of effectually heating the contents of the water-reservoir, shall also be capable of as convenient and successful use for b roiling and other culinary operations as would be possible if the reservoir were entirely dispensed with.

To this end our invention comprises a novel combination of an annular water-boiler with a system of burners arranged within, but separate from, the said reservoir, so that the reservoir is heated by lateral radiation from the burners, and the reservoir, aside from its normal function, serves to support ordinary cooking utensils above or over the flame of the burners, so that the action of the latter is effectually secured for cooking purposes.

Figure 1 is a plan view of a petroleum-stove made according to our invention. Fig. 2 is a plan view of the same, with the annular water-reservoir'removed. Fig. 3 is aside view and partial vertical section of the apparatus, with the water-reservoir in position; and Fig. 4 is a vertical transverse section of Figs. l, 2, and 3.

A is a horizontal vessel, which constitutes the fuel-reservoir of the apparatus, said fuel being rened petroleum, kerosene, or other suitable liquid hydrocarbon, and may be supported upon suitable legs a. B are the wicktubes of this reservoir, to which are provided the ratchet-wheels C, arranged in the usual relation with the wick device, arranged to raise and lower the wicks, as occasion may demand. rlhe shafts or stems D of these ratchet-wheels C extend laterallyr from the vessel A, so as to be conveniently reached and operated in raising and lowering the'wick, as aforesaid. Y

The hereinbefore-indicated arrangement of the wick raising and lowering ratchet-wheels and their stems, with reference to the wicktubes, may be ofthe ordinary or any suitable kind, and therefore requires no special description in this connection; but in order to retain the ratchet-wheels in steady and uniform position, with reference to the Wicks, and also to prevent the shafts or stems D from being bent, broken, or displaced, an adjnnctive sleeve, E, is rmly fixed to each wick- Atube, and, when necessary, braced upon the vessel A, said sleeve being around the shaft or stem D, and forming a supplemental and strengthening bearing for the same, for the purpose just hereinbefore set forth.

Above each of the wick-tubes is placed a chimney, F, made, preferably, of metal, and which, instead of being narrowed toward the top, as has hitherto been the usual plan, is iiared, or made wider at the top than at the bottom, or the part most adjacent to the wicktube.

By this means the products of combustion from the flame of the burners, as they expand from increased temperature in passing upward, are allowed free exit from the chimney.

By this means a better draft lis secured to each burner, a more uniform ilameis obtained, and, a more lperfect combustion of thefuel being secured, a greater amount of heat from a given quantity of fuel is produced than is possible w'ith burners having chimneys constructed in the ordinary manner..

For convenience and simplicity of construction, these chimneys are attached to a horizontal plate, G, itself attached to the bottom of an annular oblong waterreservoir, H. Vertical standards I are attached to the vessel A, and upon these standards rests the plate G,

and consequently the water-reservoir H. rlhe top of the reservoir His higher than the chimneys F, and affords a support for a gridiron,

or any other suitable cooking utensil, for the heating of which the apparatus may be used. The heat and hot products of combustion pass upward through the chimneys from theburner; strike the bottom of such utensil, and'heat the same in the requisite manner and degree.

Inasmuch as a certain portion of the heat from the burners-in other Words, from the chimneysis radiated laterally, the surrounding water-reservoir H is heated, and" the Water contained therein is kept constantly hot, so iong as the burners are in operation, and by this means a supply of Water heated by the Waste heat from the Water is kept constantly on hand for use on occasion. The Wa-` t ter may be supplied as required to the reser- Voir H, through a suitable inlet, c', and Withldrawn therefrom by means of a faucet, d.

Whatwe claimk ais-:our invention is- In a petroleum: -:stove,= the annularwaterreservoir H, in combination with the separate and distinct system of burners F, whereby the reservoir is heated by lateral radiation from the burners,vand the said reservoir is made toserve the double purpose of providing a supply of hot Water and of furnishing asupport for cooking utensils above the burners, specifically as herein set forth.
