VAPOR-BURNING COOKING STOVE.

SPECIFICATION formingpart of Letters Patent No. 271,158, dated January 23, 1883.

Application filed July 5, 1882. (No model.)

T 0 all whom tt may concern Be it known that 1, JOHN K. THOMAS, a citizen of the United States, residing at Go lumbus, in the county of Franklin and State of Ohio, have invented new and useful ImproveinentsinVapor-BurningCooking-Stoves, of which the following is a specification.

My improvement consists of a device placed upon the table-top of a vapor or hydrocarbongas stove for intensifying and equalizing the heat of the burner. The device is specially adapted for use with vapor-burning stoves now in use, having a table-top with openings above the burners provided with spiders for the support of the cookingvessel, leaving an unobstructed central space within the spider for the direct action of the flame upon the vessel or oven, but is equally well adapted for use with a stove-top without spider-supports for the cooking-vessels. The device consists of a flat heat-retaining chamber, the bottom ring-plate whereof restsupon the top-plate of the stove, while the top ring-plate of the heat-retainin g chamber forms the support for the cookingvessel. The bottom ring-plate of the device has a central opening and a depending collar surrounding the burner, and the top ring-plate has a cen tral deflector and an annular opening, so that the flame from the burner entering the space between the ring-plates is deflected into the annular opening and partially into the chamber formed by the top and bottom ringplates, thus retaining the heat with an intensifying and equalizing action upon the vessel supported upon the top plate. To give full effect to the contact of the flame upon the bottom of the oven or cooking-vessel the top ringplate is provided with cross-rods or surface projections, upon which the cooking utensil rests to raise its bottom above the flat surface of the stove-top.

Referring to the accompanying drawings, Figure 1 represents a vertical section of a part of the stove-top plate and an elevation of so much of the burner of a vapor-burning stove as shows the application of the heat intensifying and equalizing device thereto, and Fig. 2 a view in perspective of the flat chambered device which constitutes my improvement.

The stove is of the style in which a tabletop, a, supported by legs, is provided with openings for two or more burners, b, suit-ably supported below said table-top. In stoves of this style now in use such openings are provided with spiders c for supporting the cooking-vessel and for the diffusion of the flame against its bottom. My improvement is adapted for use with such a stove, with or without the spider-supportthat is, it takes the place of the spider-support, but maybe used with itand when so used, as shown in the drawings, the spider-support is without function.-

The device which I have designed to take the place of the spider is composed of two ring-plates, (l and 'c, joined at their circumference by lapping ring-bands f, about an inch and a half wide, the ring-plates being about ten inches in diameter and forming a heat-retaining chamber. The bottom ring-plate, d, has a central opening and adepending collar, g, adapted to fit over the burner and to leave a surrounding space for supplying it with air. The top ring-plate, c, has a central. deflector, it, connected with it by radial arms t, and an annular opening, j, about an inch and a half,

separates the said central deflector from the inner edge of the said top ring-plate and forms the issuing opening for the flame from the chamber." The bottom ring-plate lies flat upon the table-top spiders of the stove, and the collarg directs the flame into the chamber, so that striking the central deflector it spreads out into the annular space and partially into the chamber, which, retaining the heat, intensifies and equalizes it upon the oven or vessel which is supported upon the top ring-plate. The flat surface of the top ring-plate is separated from the bottom of the cooking-vessel by means of cross-rods 70, preferably of copper, clinched in said plate, whereby'the flame is allowed to spread under the vessel'as well as under the top ring-plate. Surface projections will answer this purpose, but the copper rods, which may be arranged in any suitable manner, are preferred because they increase the heating capacity of the heat-retaining chamber. Any suitable number of copper rods may be used for this purpose, and they maybe arranged in rings and cross-strands both upon the surface of the ringplate and of the central. plate deflector, but not over the annular flame-space. It will be understood that the flame-directing 2' averse collar projects through an opening in the tahie-top or through a central opening in the spider.

The device is' made of sheet-iron, and in order to provide for cleaning the chamber of the product of the flame each ring-plate is provided with a separate ring-band of equal width, lapping and fittin g each other closely, so that they can be separated ,when required, as shown in Fig. 3.

I claim 1. Thccombinatiomin a vapor-burning stove, of the table-top provided' with openings and centrally-arranged burners,with the fiat-chambered device, herein described, consisting of a bottom ring-plate, 6?, having a collar, 9, a top ring-plate, 6, having a central deflector, h, and an annular opening,j, and circumferential ringhandsfijoining said ring-plates, forminga heatretaining chamber, substantially as described, 20 for the purpose specified.

2. The vessel or oven support for vaporburning stoves herein described, consisting of top and bottom ring-plates, c d, joined by closely-fitting lapping circumferential ring- 25 bandsf, the bottom ring-plate being provided with a central opening and adepending collar,

g, and the top rm g-plate having a central deflector, h, an annular opening, j, and surface rods or proj ectionsk substantially as described, 30 for the purpose specified.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.

JOHN K. THOMAS.
