NITE' STATES IMPROVEMENT IN COOKlNG-STOVES.

Specification forming part of Letters Patent No. 82,638, dated September 29, 1868.

Cincinnati, Hamilton county, Ohio, have invented a new and useful Improvementin (look- -tug-Stoves; and I hereby declare the followmg to be a full, clear, and exact description thereof, reference being had to the accompanymgdrawings, making part of this specification.

The first partof my invention relates to such,

an arrangement of flues in a cooking-stove as will permit of the oven being surrounded on all sides by a sheet of flame of the full width of the stove whenever it is desired to use the oven for baking or other purposes, so as to afford the most direct practicable issue to the smoke consistent with baking efficiency,free from sudden turns and deflections, which in stoves using bituminous coal cause such rapid accumulations of soot.

The second part of myinvention relates to a detachable oven which can be readily removed for the purpose of cleaning the flues, 820.

In the accompanying drawings, Figure 1 is a perspective view of a cooking stove embodymg my improvement, the oven being detached, and a portion of it and of the frontplates of the stove being broken away, so as to exhibit the interior construction of the same. Fig. 2 is a longitudinal section of the stove, showing the damper elevated, so as to compel the flame to pass completely around the oven. Fig.3 is another longitudinal section with the damper reversed, so as to allow the flame, &c., to pass directly to the smoke-pipe. Fig. 4 is a transverse section of my stove,taken at the linear m of Fig. 2. Fig. 5 is a perspective view of the rear of the stove provided with a difi'erentform of damper. Fig. 6 is a vertical section of the same.

The stove A, which may be of any approved form, is provided with a customary tire-back, B, and top plate, 0. Placed intermediately between the top plate, 0, of the stove and the top plate of the oven, and parallel to both, is a plate, D, which extends across the stove from side to side, and has its front and rear end supported upon the top of the fire-back B and a frame, E. The space F between the said plates 0 D serves as aflue to conduct the products of combustion to the rear of the stove.

Placed athwartthestove are fourangle-irons, G G G G, which support the detachable oven H in such a positisn thatitis equidistant from the fire-back B,intermediateplate, D, and rear and bottom plates, I J, of the stove. The plate D, I prefer to make so as to beremovable, as indicated, so as to afford ready access to the flue N. This arrangement of the oven causes it to be surrounded by four flues extending the entire width of the stove-to wit, a rear flue, K, bottom flue, L, front flue, M, and top flue, N; and when the damper is' elevated, as shown in Figs. 1 and 2, the products of combustion pass through these flues in the order above designated. One end of the oven is provided with a marginal flange, h, which is adapted to enter a recess, a,in the side of the stove, and the other end of said oven fits snugly around the flanges b, which project inwardly from the opposite side of the stove. When the oven is in-its proper position the doors 0 c,wh'en closed, prevent it from being accidentally displaced. 7

The damper O is journaled in wings or cheeks f f that are attached to theframe E, and these wings divide the upper part of the rear of the stove into three passages, P RE, which communicate with the rear flue, K, and also with the flues F and N, communication with the latter being efi'ected by the opening S.

T is a deflecting-plate which is attached to the removable plate D, and said plate serves to deflect the fire and smoke toward the side of the stove, and thereby prevent them taking a central and too' direct course to the smokepipe, and it also serves to support the plat against sagging underintense heat.

Adoor, U, at the bottom of the fire-back, per.- mits of the flue L being cleaned of soot,ashes, &c.

The operation of my stove will be understood byreferring to'Figs. 1 and 2-. It will be seen that when the damper O is in its erect position the direct communication between the flue O and smoke-pipeV is intercepted, and the flame is compelled to descend the passagesR R into the rear flue, K, and thence along the other flues, L M N. After having traversed thelast flue, N, it escapes through the opening S into the central passage, P, and thence out through the smoke-pipe. As all of these flues K L M N are the full width of the stove, itwill be seen that the oven is completely enveloped with a continuous sheet of flame and heated smoke,

by which means the oven is maintained at a higher and more even temperature, with the shortest possible and most direct passage to the exit-pipe.

When the fire is first lighted, or whenever it is desired to use the stove without heating the oven, the damper is turned down to the position shown in Fig. 3 and the products of combustion ascend through the central passage, P, into the smoke-pipes.

Whenever it is desired to clean out theinterior of the stove it can be done by withdrawing the oven, which is the work of a few moments. The top of the oven can be cleaned at any time by simply removing the plate D.

The detachable oven, instead of being cast in one piece, as shown, may be made of two pieces, so as to separate in the middle and be drawn out from each side of the stove, and in order to make a tightjoint their meeting edges may be slightly overlapped.

1n the modification shown in Figs. 5 and 6 the damper 0 extends completely across the stove, and when it is elevated, as seen in the first figure, the flame circulates through the fines N, M, L, and K in a reverse manner to what it does with the form of damper illustrated in Figs. 1, 2, and 3. The damper being turned down, as indicated in Fig. 6, the products of combustion pass directly into the smoke-pipe without heating the oven,

It will be seen that the fire, smoke, 850., has a continuous and uninterrupted movement, and that it is not checked or reversed in its progress, thereby insuring a good draft and preventing the fines from being choked up with soot, &c.

I claim herein as new and of my invention- 1. The removable oven supported and slidin g on transverse an gle-pieces and overaflange on one st0ve-plate, and with a marginal flange fitting into a rabbet on the other stove-plate, so as to make ajoint with the plates at the respective ends of the said oven, substantially as described.

2. The four-sided oven H and fine-plate D, so constructed and arranged as to form a non-reverting and continuous flue around the oven, and to be removable to expose the flue-plates for cleansing, substantially as described.

1n testimony ofi which invention I hereunto set my hand.
