JAMES L. MEAFOY, OF MIDDLETOWN, NEW YORK.

COOKING-STOVE.

Specification of Letters Patent No To all whom it may concern:

Be it known that I, JAMES L. MEAFOY, of Middletown, in the county of Orange and State of New York,- have invented a new and useful Improvement in Cook-Stoves; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, in which Figure 1, is a transverse vertical section of my invention taken in the line w, m, Fig. 2. Fig. 2, is a longitudinal vertical section of ditto, taken in the line y, y, Fig. 1. Fig. 3, is a horizontal section of ditto, taken in the line a, 2, Fig. 2.

Similar letters of reference indicate corresponding parts in the several figures.

The object of this invention is to economize in the consumption of fuel by a very simple arrangement of means and at the same time render the stove more convenient and desirable for general use than all others that have passed under my observation.

The invention consists in having the firechamber of cylindrical form placed in the front part of the stove, and encompassed by an air-chamber communicating with the upper part of the fire-chamber by small orifices, and having a water-heater adjoining the air-chamber, the above parts being placed directly in front of the oven and also used in connection with a perforated and equalizing draft plate, as hereinafter described, whereby the desired end is attained.

To enable those skilled in the art to fully understand and construct my invention I will proceed to describe it.

A, represents the body of the stove which externally is of ordinary form.

B, is the oven placed at the back part of the stove and encompassed by a flue C, C, C, which extends over its top down at its back underneath its bottom and up again at the back where it communicates with the smoke pipe D, the flue being divided by partltion plates a, a, a, in order to obtain a reverberating draft when necessary, a direct draft being obtained when required by opening a damper E, at the back part of the upper horizontal portion of the flue at 1ts junction with the stove pipe, see Figs. 2 and 3.

In the front part of the stove A, an directly in front of the oven B, a circular fire-chamber F, is placed. This fire pot 25,573, dated September 27, 1859.

is placed within an air-chamber G, which communicates at its outer side with the external air by perforations b, as shown clearly in Fig. 1. The upper end of this air-chainber communicates with the upper end of the fire-chamber by small perforations, 0. Below the fire-chamber there is an ashdrawer H, as usual.

By the side of the air-chamber G, there is a chamber I, in which a water-heater J, is placed. This chamber I, has a door cl, at its outer side. The chamber I, air-chamber G, and fire-chamber F, occupy the space usually taken up by the fire chamber of ordinary cook stoves.

I11 the upper part of the flue G, a vertical plate K, is placed. This plate is directly back of the upper part of the fire chamber, is perforated and extends nearly three quarters of the distance across the flue as shown clearly in Fig. 3.

The operation is as follows :-VVhen the damper E, is open a direct draft is obtained as indicated by the red arrows,.the plate K, serving to equalize said draft or spread it over the upper plate of the oven, and made with all the pot holes which are indicated by dotted lines. This is effected by the perforations allowing a portion of the products of combustion to pass through the plate,the plate arresting some which pass around its end. The direct draft is permitted when the pot holes are to be used and the plate K, therefore is essential in order that all the holes may be used or occupied to advantage. This will be fully understood by referring to Fig. 3. Vhen the oven B, is to be used the reverberating draft will of course be required and the damper E, is closed. The black arrows show the direction of the reverberating draft. It will be seen by referring to Fig. 3, that the plate K, allows a portion of the products of combustion to pass at first directly toward the damper E, and they then pass around the end of the partition plate a, the other portions of the products of combustion passing around the end of plate H. The products of combustion here unite and pass down behind the oven B, at one side of the partition plate a, and also underneath the oven at one side of the partition plate a", and around the end of said plate into the other part of the vertical portion of the flue behind the oven and thence into the smoke pipe.

From the above description it will be seen that the perforated plate K, forms an essential feature of the invention and. effectually compensates for the one-sided position of the fire-chamber F. It will also be seen that warm streams of oxygen are admitted directly over the fire through the perforations 0, and gases thereby consumed which would otherwise escape, at the same time a portion of the air-chamber being interposed between the fire-chamber and the chamber 1, and the oven B, prevents the water in J, being unduly heated and kept in a warm state a few degrees below the boiling point, and also prevents the portion of the oven adjoining the fire chamber being unduly heated.

The arrangement as shown is one of economy and convenience.

I do not claim admitting air into a firechamber directly over the flame in order to consume the gases eliminated by the imperfeet combustion of the fuel, for this has been previously done. Neither do I claim any novelty in the flue C, arranged with the partition plates a, a, a"; but,

I do claim as new and desire to secure by Letters Patent,

1. The cylindrical fire-chamber F, airchamber G, communicating with the firechamber and the heater-chamber I, when combined and arranged relatively with each other and the oven B, for the purpose set forth.

2. I also claim in combination with the fire-chamber F, air-chamber G, and heaterohamber I, arranged as shown, the perforated plate K, placed in the flue O, relatlvely with the fire-chamber for the purpose set forth.
