UNITED STATES PATENT OFFICE.
CHARLES F. W'ALTHER, OF BUFFALO, NEIV YORK, ASSIGNOR TO SHERMAN S.
' JEIVETT & 00., OF SAME ILAOE.
STOVE.
SPECIFICATION forming part of Letters Patent No. 435,781, dated September 2, 1890.
Application filed April 12, 1890.
To aZl whom it may concern.-
Be it known that I, CHARLES F. IVALTHER, a citizen of the United States, residing at Bufl'alo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Stoves, of which the following is a specification.
My invention has for its object to secure a uniform draft or admission of air to all parts of the combustion-chamber of a stove, which is of such size or shape that the tendency on the part of the air is to pass with much greater freedom to one portion of the combustionchamber than to another, it being particularly adapted to cookingstoves having a long and comparatively narrow firebox and taking in the air at one end only; and to this end the invention consists in making the openings into the combustion chamber of graduated size, the smallest being near the end at which the air enters, and hence where the natural draft is the strongest.
1n the drawings, wherein I have illustrated my invention, Figure 1 is a horizontal section of a stove, seen from above and looking into the fire-box; andFig. 2 is a vertical section of a stove, showing the invention applied to a fire-box having air-openin gs through the side linings.
In the drawings, A represents the fire-box or combustion-ahamber, and B B ovens on either side thereof. The air to support combustion is taken in below the grate O at the end a. of the fire-chamber and passes through the openings 0 in the grate into the mass of burning fuel, and thence through any suitable ilue-passage to the escape-pipe. The openings 0 through the grate are of graduated size, the smallest in area being nearest o the end a, whence they gradually increase in size toward the rear of the combustion-chamber. This arrangement insures that the sup ply of air to the fire shall be practically uniform throughout the entire length of the grate, because at the rear, where the draft is Serial No. 347,626. (No model.)
the weakest, it meets with the least obstruction in passing to the fire by reason of the large size of the openings.
\Vhile the openings 0 are shown as being oblong in shape, it is evident that they may be circular or of other shape, as the invention does not depend on the shape of the openings, but on their relative size, as has been explained.
In Fig. 2 the lower portion of the side lin- 5 ing E to the combustion-chamber is shown as provided with a series of draft-openings e. These, like the openings 0, increase in size or area as they recede from the air-entrance at a, and for a like reason.
My invention is particularly intended for use in cooking-stoves using wood for fuel; but I do not limit myself to its use in a stove of this character.
\Vhat I claim is- 1. A stove having its combustion-chamber provided with air-openin gs graduated in area, the smallest being located where the natural draft is the strongest, substantially as set forth. 7o
2. A stove having a long fire-box with the opening which communicates with the external air at one end, and with openings into the combustion-chamber of graduated size, the smallest being toward the end through which the air is taken, substantially as set forth.
3. A stove having a fire-box into which the air is taken from one end only and below the grate, and having the grate provided with So openings graduated in size, the smallest being toward the end at which the air enters, substantially as set forth.
In testimony whereof I aifixm y signature in presence of two witnesses.
CHARLES F. WALTHER. Witnesses:
J. O. DowNER, H. O. OLVER.
