TO ALL WHOM IT MAY CONCERN:

Be it known that I, JACOB D. SPANG, of Dayton, in the county of Montgomery, and State of Ohio, have invented a new and improved Gas-Stove; and I do hereby declare that the following is afull, clear, vand exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this, specication, in whichl Figure 1 is an end elevation Figure 2 is a. top view.

Figure 3 is a longitudinal vertical section of the burner.

Figure 4 is a top view of the same.

The object of this invention is to construct a neat and convenient portable self-gas-generating stove, which can be easilykept in order and regulated, which is adapted to all the various purposcsof cooking, heating, 85e., and which utilizes the heat and the fuel to the greatest possible degree. I

In the drawings, .A represents the body of thestovc, being an oblong metallic case, having a series of apertures, a a a, around its walls, land provided with a cover, A, which lts tightly upon it, the cover having an opening, a', overeach burner, to receive and support th'e various cooking-utensils that may be employediir connection with the stove.

B is thc reservoir, which contains-the gasoline7 petroleum, or other substance from which the gas is to be generated, being provided with suitable ports, b b, through which it can be filled, and a pipe, b', to conduct the gasoline towards the burners.

C is a. pipe just outside of the rear wall of the stove, and lying in a horizontal positionnearly parallel with it, as seen in iig. 2. i At its centre it receives tho pipe b from the reservoir, and from different points along its inner wall, branchzpipes, c c c c, one to each burner, pass in through the wall of thestove, conducting the gasoline to the several burners. These branch-pipes pass in across the middle of the stove, then bend downward, then back to the middle, and then upward exactly under the apertures a a', where they are provided' with suitable burners, and where the gas, after being manufactured, is consumed. The burners are, by this arrangement, directly under the horizontal portion of the pipes, and, as'the gasoline passes through'the branch-pipes, arriving at the point above the burners, it is vaporized, and only the vapor passes over to the burners. The heat of the burning gas of the stove therefore serves to reduce the petroleum to gas, and the stove thus makes its -own gas and supplies itself with fuel. v

Directly under the burners are hemispherical depressions, D D, in the bottom of the stove, the Walls of which are perforated, as seen at e e c, in order to provide a constant supply of fresh airto the burners above, the object being not only to supply them with air tokeep up combustion, but to introduce the air in such a direction that it shall be heated bythe burner,'and then be thrown directly upward against the`cookin-g-vessels. From them it is deflected to the sides of thestovc, and escapes at last through the apertures aan, serving to warm the room Where th'e stove is situated. i I y i In connection with this arrangement,-I also provide deflectors, G, hinged by short arms to the upper side 'of the pipes c c above the burners, and 'n the form of circular plates radially corrugated, by which the heated nir will be more cli'eetually thrown away from a focus over the burner, and allowed to rise around the bottom ofthe pot or other cooking-utensil. i 5

Suitable stop-cocks, iz', are provided for each branch-pipe, being atixed outside of the stove, by which the supply of fuel may be shut oil' from any or all of the burners at once7 if desired, and in addition to these, another, z", bywhich the supply to all 'the burners may be instantly cutoff whenever it is necessary. By means of these 4various cocks, the i'ircs may be regulated with the utmost possible ncety. l

'lhe burners which I employ are clearly shown in figs. 3 and 4, cach burnerbeing constructed of two pieces, m n, the former screwed to the end of the pipe c iu the usual manner, and the` latter screwed 'upon the endoi` the former, as shown in ligt 3. '.lhe piece, mhas but a single hole in irt,- and that atithe centre, opening Vinto a chamber, a, within theppiece n, when the latter is in position. The piece,fa1 is provided with several holes, 11 o fu, arranged'around a central hole in its top, as clearly'seen in fig. 4, and serving to throw jets of gas at dii'erent inclinations from the vertical jet'thrown by the central hole.` This` burner can be'readily taken oii' to 'be cleansed, when required, and, if bute. single jet is needed, the upper cap n may be removed. The burner has been tested by a longcourse of practical experiment and use, and is found to be much superior tothe old burners for use in connection with gas and vapor-burning stoves.

The whole stove, thus constructed, can be supported upon any kind of pedestal F. It will need no chimney Y or Hue; it can be set in any part ofrthe building where it is most-convenient for the time being to use it, and' can be readily moved from one `place to another, as convenience may suggest. It is neat and ornamental in appearance, and can be made at less expense than any other stove used for a similar purpose.

Having thus described nay invention, what I claim as new, and desire to secure by Letters Patent, is-` The burner, consisting essentially of the parts m n, constructed as described, and operating in the manner and for the purpose set forth. J. D. S19-ANG.
