I SPECIFICATION forming part. of Letters Patent No. 410,229, dated September 3, 1889.

Application filed June 7, 1889. Serial No, 313,499. (No model.)

To all whom it may concern.-

Be it known that I, CHARLES C. AUGUSTINE, a citizen of the United States of America, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Heating-Stoves, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to heating stoves or furnaces of that class in which cold air is drawn into the apparatus and directed against the heated surfaces therein and then discharged to be conveyed to any desired point.

The features of novelty are hereinafter pointed out in the claim.

In the drawings, Figure 1 is a vertical section through the stove or furnace on a line through the flues of the ring. Fig. 2 is a detail Vertical sectional view through the ring and the-parts connected therewith on a line through the cold-air ports of said ring. Fig. 3 is a plan view of the ring.

In the drawings, A is the fire-pot, and B the ash-pit, of any desired form. Upon the top of the fire-pot is secured the ring 0. This is made of cast metal with a depending flange c for attachment to the fire-pot. The inner cylindrical body portion 0 extends upward in line with the fire-pot and is open at both top and bottom. The upper edge of this portion forms a bearing-flange upon which is supported the inner cylindrical dome D, closed at the top by a cap-piece d. Free communication is thus provided through the open cylindrical body portion of the ring between the fire-pot and the dome.

Outside the central part of the ring 0, and concentric therewith, are two vertical flanges or rims c 0 the outside one 0 being of less height. These flanges are connected to each other by an approximately-horizontal annular bottom or flange 1, and to the central body part c of the ring by the upper and lower walls of the inwardly-inclined smoke flues or ports S, which extend radially outward from the central body part across the intervening open space at the point-s shown in Fig. 3. This construction and arrangement provide supports for the outer flanges or rims, smoke-flues at a point between the fire-pot and dome, and also coldair ports 12 between the smoke-flues S. The flanges c 0 support vertical concentric cylinders E E. The space between said cylinders is closed at the top by a plate e, and said space communicates with the firepot through the flues or ports S. An opening as in the horizontal flange of the ring comm unicates with thesmoke-pipe, and from this construction it will be seen that the course of the products of combustion is through the ports S, the annular space 6, and then through the port as to the smoke-pipe, and for the purpose of utilizing the heat of the products of combustion as much as possible I provide vertical flue-strips f f (shown'for convenience slightly out of place in Fig. l) in said annular space on each side of the exit-port, so that the draft will first be upward from the ports S over the top of the flue-sheets and then down to the exit. The cold air enters the hot-air space 71. from below through the ports 19 p of the ring 0 between the flues S, and during its passage through this space it is acted upon by the heat from the cylindrical dome D, and also from the annular smokespace e,'whic h completely surrounds it. An outer inclosing-case is used, preferably, pro vided with exit-openings 0 0, and the air besides being heated in the space h is acted upon in its passage through the space h.

An important feature of my stove is the 10- cation of the fire-door in relation to the ring having the flues or ports S, and, as shown, the door is positioned below the level of the ring, so that there is no liability of choking the flues by feeding too much coal, nor is there any chance of the fuel being carelessly thrown into said ports S when filling the stove.

It will be noticed that the flange 1 is formed 0 with inclines 10 intermediate of the inclined flues S, and by reason of this construction soot and dust will not lodge in the annular smoke-space, but will fall into the inclined flues, and thence into the fire-pot. This flange 5 thus serves the twofold purpose of constituting the bottom of the smoke-space and the means for directing the soot back into the fire-chamber. I prefer to cast the ring all in one piece. The parts may be bound together Ioo by brace-rods, as '0, Fig. 1.

Having now described my invention, what I claim is- In combination, the fire-pot, the dome, th

inner and outer concentric cylinders, the ring interposed between the fire-pot and the dome and cylinders, said ring being constructed with sheets on either side of the opening, and the feed-door located in the fire-pot below the ring and the ports thereof, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

CHARLES C. AUGUSTINE.
