UNITED STATES PATENT OFFICE.

JAMES D. FIELD, OF DAVENPORT, IOIVA.

STOVE.

Specification of Letters Patent No. 24,800, dated July 19, 1859'.

To all whom it may concern.

Be it known that I, JAMES D. F IELD, of Davenport, in the county of Scott and State of Iowa, have invented a new and Improved Cook-Stove; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1, is a longitudinal vertical and central section of my invention. Fig. 2, is a transverse vertical section of the same, taken in the line w, m, Fig. 3.

Similar letters of reference indicate corresponding parts in both figures.

The object of this invention is to obtain a cook stove in which the full benefit of the heat generated by the combustion of the fuel will be obtained, and consequently a savin of the latter effected, whether coal or wood be used.

The invention consists in a novel arrangement of flues, fire chambers, and a waterheating device as hereinafter fully shown and described, whereby the desired object is attained.

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

A, represents the body or case of the stove, which is of cast iron.

B, is the oven.

C, is the smoke pipe.

D, is the fire-chamber, which is placed in a box IE, above the body or case A.

F, is a flue which extends from the bottom of the fire chamber D, over the top of the oven 13, down at its end, underneath it, and communicates with the lower end of pipe C, as shown clearly in Fig. 1.

The fire grate G, is formed of a series of tubes at, the ends of which are connected with oross-pipes b, b, one of which Z), is more elevated than the other I), as shown clearly in Fig. 2. This difference in the height or elevation of the cross pipes 11, 6, gives an inclination to the tubes at. The more elevated crosspipe b, communicates with a boiler or water heater H, some distance above its bottom 0, as shown clearly in Fig. 1. The lower crosspipe b, communicates with the boiler or heater H, near its bottom. The boiler or heater H may be of rectangular form and placed parallel with the box E.

Vithin the body A, of the stove and directly below the chamber D, there is a chamber I, having a grate J for its bottom and an ash-box K, below the grate. The chamber I, is intended for wood, when the latljfer 1is more readily attainable than coal for The upper part of the box E communicates with the smoke-pipe C, by a pipe d, which is provided with a damper e. In the box E, there is also placed a register f, said register being above the coal in the firechamber D, as shown clearly in Fig. 1. Vents 9, provided with doors are made in the flue F below the oven B; seeFig. 1.

When coal is used as a fuel D is the firechamber and G the fire-grate. A direct draft is given the fire in kindling by opening the damper 6, closing the register f, and opening the vents g, in the flue F. When the coal is fully kindled, the damper e, and vents g, are closed, the register f, opened, and the products of combustion pass downward from the fire-chamber and around the oven B, through the flue F, into the pipe C. In case wood is used for fuel, the operation is precisely the same. The water in H will be heated in consequence of its passing through the tubes at; and by having said tubes inclined, a circulation of the water through the tubes is briskly kept up; the warm water rising as the cooler water descends. The inclination of the tubes a, of the grate G, greatly assists this circulation of the water and prevents the tubes a, from burning out.

It will be seen that the fire-chamber I, admits of being made as large as may be desirable for wood without at all affecting the fire-chamber D; and the box K, will receive the ashes of either fire. The whole arrangement is extremely simple and efiicient and will prove a valuable acquisition for the kitchen.

I do not claim separately any of the parts,

irrespective of arrangement and construc tion; but

the smoke-pipe C, to operate as and for the purpose set forth.

JAMES D. FIELD.
