THOMAS WHITE',v oF oUINcY, ILLINOIS.

IMPRQVEMEN'I` lN `COOKING-STOVES.

Specification forming part of Letters Patent No. 126,763, dated May 14, 1872.

To whom tt may concern:

Be it known that I, THOMAS WHITE, of Quincy, in the county of Adams and State of Illinois, have invented a new and useful Improvement in Cooking-Stoves; and I do declare that the following is a true and accurate description thereof, reference being had to the accompanying drawing and to the letters of reference'marked thereon and being a part of this specification, in which- Figure l is alongitudinal vertical section of my stove through the center thereof. Fig. 2 is a rear end elevation of the same, the back plate having been removed. Fig. 3 is an inverted plan of the bottom, the bottom plate being broken away to show the bottom-flue strips; and Fig. 4 is a perspective view of the back division-fine plate.

The nature of this invention relates to an improvement in the construction of the back lues of a cooking-stove, whereby, from their peculiar construction and conformation, the stove will have a better draught when the latter is reverted, and the flame will have a better chance to spread under the vessels placed in the holes in the top plate; and it consists in the peculiar conformation of the back division-fine plate, and its arrangement with relation to the oven and back plates of the stove, and with the flue-strips in the bottom chamber thereof.

In the drawing, A represents the bottom plate, B the top plate, C the side plates, D the front plate, and E the back plate, inclosin g the fire-place and an oven, G, under which there is a base-chamber. The drawing shows a stove having an extension top, but the latter is not necessary, andmy improvement applies to the short or square-top as well. The base-chamber is divided into a middle and two side flues by two vertical-nue strips, H H, which extend from the back plate to a point under the front part of the oven. I is my improved back division-flue plate, cast in the peculiar' form shown in Fig. 4, the lower part of which has an inwardly-flanged arch, a, and at each side thereof an outwardly-flanged half-arch, b, sprung from the lower ends of the former, which rest upon and interlock with upward extensions c of the flue-strips H back of the rear oven-plate, on which there is cast an arched rib, d, to receive and support the edge of the arch a, the edges of the anges b abutting against the back plate E of the stove. The upper part of the plate I is inclined forward, and carries a sliding damper, J, in suitable guides, and, by means of the rod e may be made to close or cover the openings fin said plate, or disclose them, at will. In the former case the iiame passes in a broad sheet under the entire top plate, and down behind the oven-plate, Where it is divided by the arched top ofthe ilange d, and passes down between the outer Sides of the flue-strips H and the side plates C to the front ends of said strips, returning between theminto the arch a; thence through' the pipe-hole in the top-plate pass to the chimney. By disclosing the holes or openings f a direct draught is obtained. To Support the ends of the plate I, the side plates are cast with ribs g, corresponding in outline thereto, which support the edges of said plate. The extensions c of the flue-strips may be cast therewith,or to the plate I, as prolongations thereof. The curves of the arches, where they are flanged, should be easy, so as to retard asy little as possible the passage of the smoke and gases of combustion.

It will be seen that by the peculiar construction of the plate I the heated currents, when reverted, in their upward return, must heat the back plate of the oven at the central portion thereof, as well as at the ends, before escaping up the chimney, insuring uniformity in the baking process, as well as equal expansion of the back plate of the oven, overcoming the tendency of unequally-heated stoveplates to warp and crack.

The back drop-lines are easily cleaned by introducing a` Scraper through the apertures in the plate I, which is inclined at the plane plates H, and arranged between the back of of the damper, loosening the soot adhering to Ythe oven and the back plate E, substantially the walls of the lues, and then removing itY as and for the purpose set forth. through an opening in the bottom chamber of 2. The ribs d g, for supporting the plate I, the stove. as shown and setforth.

What I ela-im as my invention, and desire to THOMAS WHITE. secure by Letters Patent, is-

1. The back division-flue plate I, construct- Witnesses: ed as described, and provided with the damp- H. NEWLEY, er J in combination with the division-flue DICKERsoN MCAFEE.
