IMPROVEMENT IN COOKlNG-STOVES.

Specification forming part of Letters Patent No. 141,508, dated August 5, 1873; application filed May 10, 1873.

To all whom it may concern:

Be it known that I, WILLIAM W. KARSH- NER, of Aubrey, in the county of Johnson and State of Kansas, have invented a new and useful Improvement in Cooking Stoves, of which the following is a specification:

Figure 1 is a top view of my improved stove, the boiler-hole covers being removed. Fig. 2 is a front view of the same. Fig. 3 is a vertical longitudinal section of the same taken through the line 00 m, Fig. 1.

Similar letters of reference indicate corresponding parts.

My invention has for its object to furnish an improved cooking-stove, which shall be so constructed that all the heat may be thrown to the top of the stove and directed to one or more of the boiler-holes, as desired, to enable cooking to be done without heating the lower part of the stove; or all the heat may be made to pass aroundthe oven, to enable the baking to be done without heating the upper part of the stove; or the heat may be made to circulate through both the upper and lower parts of the stove before escaping into the chimney; or may be made to pass directly into the chimney without heating either the upper or lower part, thus enabling the fuel to be used with great economy, and the room to be kept comparatively cool when desired, it being necessary to use no more fuel than the special purpose may require. The invention consists in the improvement of stoves, as hereinafter described and pointed out in the claim.

A represents the body of the stove, which is constructed in the ordinary manner. B is the fire-chamber, whiclris provided with a fire-grate, (J, in the ordinary manner. The fire-chamber B is arched or lined upon the top and sides with fire-brick, soap-stone, iron, or equivalent substance, D. The front, the door, and the lower part of the rear should also be lined, an opening being left at the upper part of the rear end for the heated products of combustion to pass through, which opening should be provided with a damper, E. The top or arch of the lining D, which should be at a little distance below the top plate of the stove, should have holes formed in it corresponding with and directly beneath the boiler-holes in the said top plate of the stove. The holes in the top lining of the fire-chamber should each be provided with a damper, F, as shown in Figs. 1 and 3. The opening leading from the space Gr, between the top of the fire-chamber and the top plate of the stove, opens directly into the flue H, which leads to the chimney, which opening is provided with a damper, I. J is a flue, leading down the rear side of the fire-chamber, formed between the bottom of the fire-chamber B and the top of the oven K, down between the front of the oven K and. the front plate of the stove A, back between the bottom of the oven and the bottom of the stove, up along the rear of the oven, and out through the flue H. L is a draft-flue, which leads into the ash-chamber M below the grate C, so as to discharge the air to support combustion beneath the middle part of said grate, and ,thus'make the combustion more perfect.

One or more of the draft-tubes L may be used, and they may lead in from the door or from some other part or parts of the stove, as may be desired or convenient. The draft-tube L, at its outer end, may be provided with a damper, N, to enable the combustion to be controlled, as desired.

0 is the hearth, which is made with a large opening through it, and is provided, both upon its upon its upper and lower sides, with flanges or seats to receive the slide P upon its upper side, and the detachable ash-box Q upon its lower side.

With this construction, when it is desired to cook without baking, or heating the lower part of the stove, the damper E is closed, the damper I is opened, and one or more of the dampers F, according as one or more of the boiler-holes are to be used. This allows the heated products of combustion to enter the spaceG directly beneath the boiler hole or holes being used, and to pass out through the 'fiue H without heating the lower part of the stove. By closing the dampers F and I and opening the damper E the heated products of combustion will pass, through the flue J, entirely around the oven, and will escape through the flue H, enabling baking to be done without heating the upper part of the stove. By closing the damper E. and I and opening the dampers F the heated products of combustion will pass into the space Gr, thence around the oven through the flue J and out through the flue H, heating the whole stove, enabling both cookingand baking to be don e, or the whole radiating-surface of the stove to be used for warming the room. By closing the dampers F and opening the damper E and I, the heated products of combustion will pass directly into the flue H, without warming either the upper or lower part of the stme.

Having thus described my invention, Iclaim astnew and desire to secure by Letters Paten The arrangement of the dampers E F I in connection with the opening in the rear end of the lined fire-chamber, the openings in the top of said lined fire-chamber, the space between the top of the stove and the top of the fire-chamber, the flue J, and flue H, substantially as herein shown and described.
