BED-PLATE I'OR BASE-BURNING WOOD-STOVE.

The Schedule referred to in these Letters Patent and making part of the m To all whom it. may concern:

Be it known that 1, CHARLES D. Nnwron, of Troy, in the county of Rensselaer, and in the State of New York, have invented an provement in Base-Burning Wood-Stoves and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawing, making a part of this specification, in which- Figure 1 is a vertical cross-section of astove, in which my improvement is shown as applied.

Figure2is a vertical longitudinal section of the same.

Figure 3 is a detached perspective view of my improvement.

Letters of like name and kind refer to like parts in each of the figures.

My invention is an improvement upon a base-burning wood-stove, having a downward draught, invented by Elihu Horsford; and

It consists of a hollow bed-plate for supporting the fuel-chamber, the interior of which serves as a flue for the admission of air into the fuel and combustion-chambers, for, the purpose of insuring more perfect combustion, and also for the purpose of protecting said bedplate from the intense heat to which it is subjected.

In order to properly illustrate my invention, I will first,briefiy explain the construction and operation of the aforesaid stove, (as shown in figs. 1 and 2,) and then proceed to describe my improvement.

In the annexed drawing- A represents the bottom,

B, the sides,

0 and O, the ends, and

D, the top of a box-stove of the usual form.

E represents the fuel-chamber, open at its bottom and front end, the latter of which is secured to the front plate C, while its rear end is supported by legs,

resting upon the bottom of the ash-pit a.

Said fuel-chamber is somewhat smaller than the shell of the stove, so that a space is left between them, E, which serves as a' flue for the passage of the heated air to the chimney.

Extending around the base of the fuel-chamber E is a flue, e, to which the air is freely admitted, through openings in the front plate O.

G represents the grate, corresponding in size and shape to the base of the fuel-chamber, supported by legs, resting upon the bottom of the ash-pit, its upper surface, at the edge, being very near to the base of said chamber, so that sufiicient space only is left between them to permit of the passage of the gaseous products of combustion, and of the ashes.

The grate is highest in the centre, and from thence slopes downward to either side. The same incline is also given to'the rear end.

Secured directly beneath the grate, and corresponding in size therewith, is a plate of metal, H, between which and said grate is left a suificient space to allow a current of cool air to pass freely, for the purpose of preventing the grate from becoming overheated.

The air is admitted through an opening, 0', in the front plate 0, and, after passingbetween said plate and the grate, mingles with the gas and smoke from the fuel-chamber, and assists in insuring their combustion.

The door, I, isof the usual form and construction, being provided with one or more openings for the admission of air, which are closed, when desired, by a slide.

The hearth, a, is made to close tightly.

Fuel being placed within the chamber, and ignited, the smoke and gas are drawn downward, through the burning fuel,"into the space beneath the chamber, where they are met by a current of air passing out from between the grate and plate H, and consumed, with the most intense heat, which is so great as to cause much expense and trouble, from the frequent burning out of the base of said fuel-chamber, experience having proved that the air will not circulate through the flue c with sufiicient rapidity to protect the base.

To obviate these objections, and also to secure more perfect combustion of the, gas and smoke, is the object of my invention, which consists of a hollow bed-plate, K, upon which the fuel-chamber E is supported, having, upon the sides next the fuel-chamber and the flue F, a number of small openings, k k, communicating with its interior, which, in turn, communicate with the open air, by means of suitable openings in the front plate 0, or by hollow legs. I

The draught of the stove is sufficient to cause a strong current of cold air to pass through the bed-plate, so as to entirely prevent overheating, and, as the air passes into the fuel-chamber and flue F in small jets, it is thoroughly mixed with the gas and smoke, and assists maplaced upon either or both sides of the base of the fuel-chamber.

The advantages claimed for this invention are, that it furnishes a complete protection to the base of the fire-box, or fuel-chamber, and much lessens its cost, as, by its use, the flue around the base of said fuelchamber can be dispensed with, and fire-brick used.

Having thus fully set forth the nature and merits of my invention,

What I claim as new, and desire to secure by Letters Patent, is-- I The within-described bed-plate, K, constructed and arranged substantially as and for the purpose shown. In testimony that I claim the foregoing, I have hereunto set my hand, this 4th day of January, 1869.
