IMPROVEMENT IN PETROLEUM-Noves.

Specificationl forming part of Letters Patent No. 48,732, dated July 11, 1865. i

To all .whom it may concern:

Be it known that I, HAMILTON E. SMITH, of Cincinnati, Hamilton county, Ohio, have invented a-new and. useful' Petroleum-Stove; and I do hereby declare the following to'be a `full, clear, and exact description thereof, ret' erence being had to the accompanyingr drawings, making part of this specilieation.

My invention relates to a portable cooking apparatus to be heated by'a series ot' petroleum or other hydrocarbon lamps, the various boiling, baking, and other compartments being capable of being operated, either sepa rately or in conjunction, by the use of one or more lamps, vas may be desired.

Figure lis a perspective view ot a stove Fig. 2 is a vertical section thereof.

A 1s a reservoir for petroleum, coaloil, or other burning-fluid.

B B B B are lamp-burners of' any approved construction.

Instead of the customary glass-chimneys, I provide chimneys C, of sheet metal,` which chimneys may be bulged opposite the liame,

',chamber and independent burners-#one or and may taper upward and downward. Each chimney is furnished with a window, D, of mica, which, affording a view of the llame, en-

` ables the operator to know whether to elevate or depress the wick.

E is a stand provided with racks F for supporting ata suitable height above the burners anoven, G, and boilers or kettles H and I. The oven G has two circular apertures, J J', i'n its bottom plate immediately over the chimneys .of the -two central burners, a small interval in height being left between said chimneys and the said plate to enable the spent and cooled air to escape from the oven, so as to provide room for the heated emanations from the burners. The interior ofthe oven is so arranged as to be capable of being separated into two compartments by a vertical plate or Y partition, K, and each ot' these compartments is again divided into sub-compartments 'by meansof floors or horizontal plates L. Vertical division and horizontal subdivision is represented in Fig. 1. The said mode of division enables the use of one side only of the oven when a small amount ot' cooking is to be done, thus economizing fuel and avoiding ex- This The plates K and L are retained y in their places by flanges M on the interior surfaces of the oven, and are capable of being withdrawn entirely, so asA to leave the entire interior ot' the oven unobstructed; or the plateK may be used fora horizontal diaphragm, as in Fig. 2.

The chimneys of the burners B" and B'H" a very speedy and active ebnllition of the water.

in the boiler.

S is a water-pan supported on perforated flanges s, for insuring-a free circulation of heat around the pan.

T is a perforated plate or grid for cooking meat, fish, dic.

It will bev seen that the separate hot-air more to each chamber-enable the optional use of one or more departments of the baking and boiling apparatus.

I claim herein as new and ot' my invention- 1. The series of petroleum or coal-oil burners B B' B" B, in connection with-a corresponding number ot'scparate hot-air chambers or receivers, Gand N, having venta ges for spent air at their bottom por-tions only, substantially as set forth.

2. In connection with two or more independent burners, B B', the oven G, capable ot' vcrtical subdivision, in the manner and for the purpose explained.

3. In the described combination, with a petroleum-stove, ofthe tubular hot-air'chambered boilers, whose ventage for thespent air is at the bottom otl their chambers, as set forth.

In testimony of which invention I hereunto set my hand.
