IMPROVEMENT IN OOOKIN G STOVES.

"TO ALL WHOM IT MAY CONCERN:

Be it known that I, JOSEPH C. HENDERSON, of the city and county of Albany, and gtate of New York, have heretofore invented certain new and useful improvements in Stoves, upon which Letters Patcnt'of the United States of America weregrantcd to me, bearing date the 29th day of May, A. D. 18 60, and which said Letters Patent were on or about the 30th day of June,A. D. 1863, duly surrendered and reissued on an amended specification in one division or patent; and I do hereby declare that the following is a full, clear, and exact description ofuthenature, construction, and mode or manner of the use and operation of that part of my invention relating to Cool ting Stoves or Furnaces, reference-being hereby had to the accompanying drawings, which make a part of this my new, corrected, and amended specifidation; and I do now surrender the said Letters -Patent, in order that the invention and improvements aforesaid may herein be divided and be more fully specified,

\ described, and set forth, and by such divided, amended, and corrected specifications, claims, and drawings, my

rights thereto and therein shall be more fully and permanently protected, as by law provided.

Like letters represent and refer to like or corresponding parts.

. Figure 1 is a vertical section of a stove containing my said invention and improvements, each being fully hereinafter described and-set forthi Figure 2 is another vertical section, showing a modificationof same invention, more fully hereinafter described.

Thc objec t' of my invention is to overcome the principal objection to the use of soft or bituminous coal in stoves or furnaces, and to prevent smoking or filling up of the fines, and to make a more perfect combustion of the smoke and gases arising therefrom. 7

The nature of my invntion consists in the employment of a coal or supply-chamber separate from the combustion-chamber of the stove or furnace, and soconstructed that the gaseous matter from the fresh coal in the supply-chamber must pass into, through, or over the burning fuel in the combustion-chamber and thereby be consum ed, substantially as hereinafter stated and set forth. It also consists in the employment of'a combustionchamber contracted at the top inorder to retain the gases evolved from the fuel until they are completely consumed, or nearly so, substantially as hereinafter specified and set forth. It also consists in the employment of a division plate between the supply and combustion chambers, through which air may be introduced to the fire to promote a more perfectcombustion, as hereinafter specified and set forth; It also consists in constructing the plate which forms the side of tho combustion-chamber opposite said division plate in such a manner that air maybe-"introduced through it into the fire, substantially as hereinafter specified.

- Having thus described the nature of my said invention, and to enable others skilled in the"art to which it relates to make and use the same, I will here proceed to describe the construction and operation thercofi which is'as follows, to wit:

e, figs. 1 and 2, represents a coal-supply chamber, and Z a combustion-chamber, which chambers are separated from each other by the division plate or partition, g. At the bottom 'of the combustion-chamber is the grate It, through which air is supplied to the fire. The coal may be placed in the supply-chamber through an opening in the top of the stove, as in fig. 1, by raising the lidfior as atf, fig. 2, through an opening in front of the stove. The partition, or division plateg is constructed hollow, with openings at h, to admit air to the surface of the fire. [lhe combustion-chamber l is contracted at the top for the purposeof preventing the too free escape of the gases of combustion. This narrow top or throat is formcd by the employment of the plate p, which is alsoconstructcd hollow, with apertures, h, for the admission of air to the surface of the fire. In fig. l the air is admitted to the intcriorof the plates gaudy), by apcrtures'in the sides of the stove at z In fig. 2 the air is admitted to the partition g, through the openings-i in the front of the stove, and to the-division plate]; from the interior of the oven through the passage t, thus furnishing air to the fire, and ventilating the oven at thesame operation. In operating a stove or furnace containing my invention, a fire is first built in the combustion-chamber t; after it is well started the supply-chamber c is filled with/fresh coal, and the lid closed. As the fresh coal becomes heated it gives oil its volatile portions in the forin of gas, which is carried by the draught under the division plate 9, and into the fire. The throat q of the combustion-chamber being narrow, the too rapid escape of the gas is prevcntcd,'whiic the air rushing in from theapertures h It in the plates g and prcndcrs its combusar s 2 tion complete. As the fuel in the combustion-chamber is consumed, the coal in the supply-chamber nearest the fire, and which has parted with nearly all its gaseous products, is pushed on to the .grate and fresh coal supplied in its place. By these means nearly all the smoke generated by the fire is consumed, thus and thereby greatly increasing 'the pmduction ol' heat and preventing the clogging of the flues and other annoying consequences of leavingthe smoke unconsumed from such coals or fuel. 7

Having thus described the construction and operation of my said invention and improvements, what I claim as my invention, and desire to secure by Letters Patent, is v i 1. The employment of a supplyechambcr, a, separated from the combustion-chamber l, by means of the division plate g, or any equivalent therefor, and each so arranged that the fresh fuel shallvbe fed at the side of the burning fuel, in the manner substantially as and for the purposes herein described and set forth;

2. I claim the combustion-chamber l, contracted at the top to prevent the too rapid escape of the gases of combustion, in combination with the supply-chamber e, substantially in the mannerand for the purposes hereinbefore described and set forth. 7 i I 3. I claim the employment of the division plate or partition g, or its equivalent, constructed and arranged as to divide the fire-chamber or chamber of combustion, and thereby constitute the chambers l and e in the manner and for the purposes substantially as herein described and set forth.

4. I claim so constructing and arranging the said division plate g, between said chambers l and e, that atmospheric air may be admitted into and through it to the fire, so as to more perfectly consume the gases as they are evolved from the burning fuel, in the manner substantially as herein described and set forth.

'5. I claim the employment of the plate 10 forthe purpose of retaining the gases in contact with the fire until they are entirely consumed, substantially as hereinbefore described and set forth. 7

6. I claim constructing the said platep in such a manner-that air canbe introduced-through it to the surface of thefire, substantially as and forthe purposes hereinbefore specified and'set forth.

7. I claim the supply-chamber e, combustion-chamber Z, division plate g, and plate 25, all combined and operating,' substantially in the manner and for the purposes hereinhefore specified and set forth.

8. I claim the employment of the narrow or contracted throat q, when applied to cooking stoves or furnaces in the manner and for' the purposes snbstantially as herein described and set forth.

9. I claim the employment of the supply-chamber e, when applied to cooking stoves or furnaces, and therein constructed and arranged immediately in front of the combustion-chamber, substantially in the manner and for the purposes as herein described and set forth. In testimony whereof I have on this 23d. day of May, A. D. 1866, hereunto set my hand.
