UNITED STATES PATENT OFFICE.

MARCUS L. HORTON, OF LEBANON, NEW HAMPSHIRE.

STOVE.

Specification of Letters Patent No. 24,559,11atec1 June 28, 1859.

T 0 all whom it may concern:

Be it known that I, MARCUS L. HORTON, of Lebanon, in the county of Grafton and State of New IIampshire, have invented a new and Improved Cooking-Stove; and I do hereby declare the following to be a full and exact description thereof.

The nature of my invention consists in so arranging and combining an elevated oven with a cooking stove, as that while the flame and hot products of combustion shall be made to pass entirely around and heat the oven, a current of air shall also be heat-ed and made to pass around the oven to be conducted away for the purpose of giving warmth elsewhere; at the same time a portion of such heated air shall find its way into the oven to equalize its temperature and act as an absorbent of moisture, thereby obviating the necessity of using brick, soapstone, or other similar drying agents.

In the accompanying drawings Figure 1 is a top view of the stove with the oven removed. Fig. 2 is a section through the fire chamber, fire fines, oven, &c., on the line 0 O of Fig. 1. Fig. 3 is a section through the hot air flues on the line [I [I], of Fig. 1. Fig. at is a section through the oven on the line A A Fig. 1, and Fig. 5 is a cross sec tion through the fire chamber showing the grate bars. The black arrows indicate the direction of the air currents, and the red arrows show the fire currents.

A is the fire chamber; B are hollow grate bars, the air spaces in which communicate with the external air through the holes a, a, Figs. 3, 5, and with the space C behind the back plate of the fire chamber. From this space C, a flue D, of say about one third of the width of the stove, extends centrally back to and communicates through the opening 5, with the fines E, E, inclosing the oven F and entirely surrounding itexcept at the openings 0 Figs. 3 and 4 which establish a connection between the hot air flue and oven. From the flue E on the top of the oven are openings (Z through which the heated air may be carried away through pipes or fiues to other places.

Extending back from the fire chamber, on each side of and parallel with the air flue D, are the fire flues G, communicating through openings e c, with the fiues H, H, also surrounding and inclosing the oven F and occupying the space between its sides and the hot air flues E, E. A collar f afiords the means of connecting the fiues H, H, with the chimney by a pipe. In the center of the top of the oven is a ventilator I, opening into the flue H at the collar f, covered with a hood g Figs. 3 and 4t to keep anything from falling in from the chimney and furnished with a valve h on the inside of the oven for regulation or complete stoppage. The flame and gaseous products of combustion pass along the flues G, G, through the openings 0 0 into the fines H on each side of the oven, pass up over it into the flue H and out into the chimney through the collar f. At the same time cold air rushes in through the openings a a into the hollow grate bars, passes into the space C, becoming heated on its way, thence into and along the flue D until it rises into the flues E, E, and a portion of it passes into the oven through the openings 0, the rest of the hot air rising to the space E above the oven, to be conducted away from the openings (l to wherever it may be desired. The hot air does not fall in temperature in its passage through its flues as it is kept hot by its proximity to the fire fiues.

Having thus fully described my invention what I claim as new, and desire to secure by Letters Patent is The ventilator I, with valve 7L, and hood 9, as arranged and in combination with the chambers H, H, E, E, and fines G, G, and D, operating, as described, and for the purpose set forth.

MARCUS L. HORTON.
