STRAW BURNING STOVB..

STATES PATENT Tirreno STRAW- BU RNING STOVE.

SPECIFICATION forming part of Letters Patent No. 378,786, dated February 28, 1888.

Application filed J" une E27, 1887. Serial No. 242,670. (No model.)

To @ZZ whom, t may concern,.-

Be it known that I, FRED GIRTANNER, a citizen of the United States, residing at Big Stone City, in the county of Grant, Dakota Territory, have invented a new and useful Improvement in Straw-Burning Stoves, of which the following is a specification.

My invention relates to an improvement in straw-burning stoves; and it consists in the peculiar construction and combination of devices, that will be more fully set forth hereinafter, and particularly pointed out in the claims.

In the drawings, Figure lis a perspective View of a straw-burning stove embodying my improvements. Fig. 2 is a vertical longitudinal sectional View of the same. Fig. 3 is a horizontal sectional'view taken on the line x .fr 0f Fig. 2.

' A represents themain body ofthe cook-stove, which is rectangular in shape, as shown, (or may be rounded,) and is provided on its lower front side with a forward-projecting fire-box, B, the sides of which are vertical, (or may be inelined,)andtl1e front end of which is rounded, as shown. In the bottom of theire-box, at the frontend thereof, is an opening, C, which is adapted to be closed or uncovered bya slide, D.

E represents a removable ash-pan, which is arranged on the under side of the firebox and extends nearly to the door. The stove is supported upon suitable legs, F.

The main body of the stove communicates directly with the rear side of the fire-box, and arranged horizontally in 'the main body of the stove, about midway between the lower and upper sides thereof, is a diaphragm or plate, G, which divides the stove into a lower compartment or chamber, H, and an upper compartment or chamber, I. The rear corners or rear portions ofthe diaphragm or plate are cut away, as shown in Fig. 3, in order to establish communication between the upperv and lower chambers.

K represents a vertical longitudinal partition-plate, which is arranged under the center of the diaphragm G, and extends from the same to the bottom of the stove, the front end of the said plate being at the front end of the main portion of the stove, and the rear end of said plate extending to the rear side of the stove,

so as to dividethe lower compartment or chamber thereof into two parallel flues, L and M. Other chambers may be made by subdivding these chambers in same way as above.

N represents a valve which is arranged at the frontend of the flue M, and is provided with an upward-extending operating-rod, O, which projects above the upper side of the stove, and has its upper end bent at right angles to form ahandle, P. On the upper side of the main body of the stove are the usual openings, R, for the cooking utensils, and in the upper side of the stove, near its front edge, is an opening, S, for the attachment of the stove-pipe T. Directly underneath the opening S, and in the diaphragm described above, is .an opening, R, provided with a valve, R2, to give a more direct Yconnection with lire-box B and stove-pipe T.

The front end of the fire-box is provided with a hinged door, U, having a damper, V, and in the upper side of the nre-box i's an opening, around whichis arranged the vertical collar or flange WV.

X represents a vertical feeding druunwhich has its upper end closed and its lower end open, and adapted to fit in the collar orfiange WV and rest on the upper side of the lire-box. Said feeding-drum is provided on opposite sides with handles Y, by means of which it may be removed from the fire-box or placed thereon, and in the lower ends of the feedingdrum is a hinged valve, Z, provided with an adj usting-arm, A', that curves downward and forward therefrom, is provided in one side with a series of notches, D', and passes through l an opening in the front side of the feedingdrum, and is thereby adapted to have either of its notches engaged to one side of the said opening, so as to secure the valve at any desired adjustment in the feeding-drum, according to the'amount of fuel it is desired to supply to the fire-box.

The operation of my invention is as follows: By partly opening the valve in the feedingdrum straw is fed therefrom into the fire-box, where itis ignited. Then the damper N is opened, the flames, smoke, and products of combustion sweep rearward from the fire-box through the flues L and M, and from thence upward over the diaphragm or plate G into the upper ehamber,I,thereby thoroughly heating the stove. The smoke and products of combustion escape through the stove-pipe T. When the damper is closed, the smoke, iiame, and products of combustion pass rearward through the flue L only, and from thence upward into and through the upper chamber, I, thereby applying the major portion of the heat to one side of the stove when it is desired to do so. The valve at R is opened when fires are started, to give desired draft.

The ashes may be removed from the fire-box from time to time byopening the slide C and sweeping the ashes into the ash-pan E. Vh en the latter becomes filled with ashes, it may be removed and discharged of its contents. The damper in the door U enables a sufficient quantity of air to be 'admitted to the tire-box to promote combustion.^

Having thus described my invention, I claim- 1. rlhe strawburning stove having the main portion A, the fire-box extending therefrom and communicating therewith, the horizontal diaphragm G, arranged in the portion A and dividing the same into an upper and lower compartment, said diaphragm having thev opening at its rear corners communicating with the said compartments, the vertical longi` tudinal diaphragm K, dividing the lower compartment into horizontal flues L and M, the

damper N at the front end of one of the said lues, the damper R2 in the front end of diaphragm G, at the center thereof, the top of the stove being provided with the escape flue or openings, arranged directly above the damper It, substantially as described.

2. A straw-burning stove having the main portion A, provided in its lower side with the longitudinal flues' L and M, the chamber I, arranged above the said flues and communicating with the rear ends thereof, the escapeopening in the upper side of the stove to communicate with the stove-pipe, thev damper R2 in the bottom of the chamber I, directly below the escape-opening, the fire-boX arranged on the front side of the main portion A and communicating with the lilies L and M, the feedingdrum arranged on the upper side of the fire-box, the slide in the lower side thereof, the removable ash-pan arranged under the fireboX, and the damper N, arranged at the front end of one of the iues, for the purpose set forth, substantially as described.

In testimony thatI claim the foregoing as my own I have hereto affixed my signaturein presence of two witnesses.

FRED GIRIANNER.
