UNITED STATES PATENT OFFICE.

JOSEPH C. HENDERSON, OF ALBANY, NEW YORK, ASSIGNOR TO RATI-IBONE & COMPANY, OF SAME PLACE.

STOVE.

Specification of Letters Patent No. 24,844, dated July 19, 1859.

To all whom it may concern:

Be it known that I, Josnrrr C. HENDERSON, of the city and county of Albany and State of New York, have invented, made, and ap plied to use certain new and useful Improve ments in Cooking-Stoves; and I do hereby declare that the following is a full, clear, and

exact description of the construction and operation of the same, reference being had to the annexed drawing, making part of this specification, wherein Figure 1, is a perspective view of the out side of a stove fitted with my improvements. Fig. 2, is aperspective view with the side plate partially removed to show the parts.

Similar marks of reference denote the same parts.

In the construction of stoves, openings heretofore have been made in the oven, to convey away vapors and fumes from articles that are being baked in the oven; there have also been other stoves in which a radiating air chamber or space has been provided between the oven and the fire, to prevent too great radiation; other stoves have also been made with doors at the forward part of the oven to be opened to equalize the heat when a portable oven or reflector is placed in front of the fire for roasting or similar purposes. All these devices however differ essentially from my said invention which consists in an air chamber so arranged in connection with the oven and the fire, that a descending draft, the whole width of the stove, passes between the oven and the fire and enters into the fire to promote combustion. I also make use of an auxiliary heating flue behind the front plate of the stove,

between that and the firebox, which opens into the front part of the oven, so that the draft first becomes highly heated, then passes into the oven, and thence to the fire, by which a hotdraft is supplied to the fire that greatly promotes a perfect combustion; thence the draft travels the flues of the stove passing away as usual. By this means I am enabled to bake with a heated current of air in addition to the radiation, ventilate the oven, and make a far more perfect combustion of the fuel.

In the drawing a, is the top plate of the desired size and shape, 6, is the hearth, and c, the oven beneath which the returning flues are arranged in any usual manner, d, is the ring for the pipe, 6, is the fire box and f, is

the door thereof in the side plate 9, of the stove, and h, is the oven door. 2', is a hearth and 7a, a damper at the end of the ash box Z. These parts thus far may be of any desired size or shape, in the ordinary manner; m, is a division plate forming an air chamber between the fire box and the oven, opening at the top into the oven, and at the bottom into the ash box Z, so that the draft to the fire is taken out of the oven, through this chamber, except when the damper 7c, is opened for the purposes of kindling the fire.

The front plate of the fire box connects with the forward end of the oven, where a damper n, is provided, and openings or a damper 0, are provided near the top of the front plate.

,0, p, are doors which inclose the front of the stove from a hot air flue; said air coming in contact with the front part of the fire box is highly heated and passes into and through the oven in the direction of the arrow promoting the efficiency of the oven because the entire heat from both sides of the fire is taken into the oven, from the one side by the current of air and from the other by radiation, and a hot blast is supplied to the fire promoting combustion, and then the hot gases make the circuit of the oven through the flues as usual, heating said oven in a very uniform and efficient manner.

When desired the doors 7;, p, can be thrown open and a roaster or reflector placed in front, which will act to roast or bake by the radiated heat of the front plates; and if the article being baked in the oven 0, will be affected by the vapors from out of this reflector, the damper a, may be closed and the ash box damper k opened.

It will be seen that by forming a damper in the front end of the oven plate near the bottom of the oven, and causing the hot air to circulate through the same a much better operation is produced by heating the lower and front part of the oven, than in those ovens that are entirely open at the front end behind the doors; besides, this damper,when closed, keeps in the heat of the oven when a roaster is used in frontof the radiating plates.

Having thus described the nature and operation of my said invention, I wish it to be understood that I do not claim a fire pot and ash box over the oven, neither do I claim an air space between the fire and oven,

of the oven in connection with the descending flue between the front plate and fire box, whereby the oven can be entirely closed when the stove is in use for roasting as specified.

In witness whereof I have hereunto set my signature this eleventh day of February JOSEPH G. HENDERSON. Witnesses:

LEMUEL W. SERRELL, is THOMAS G. HAROLD.
