SOFT-COAL FURNACE.
SPECIFICATIQN forming part of Letters Patent No. 624,009, dated May 2, 1899.
Application filed July 19,1897. Serial No. 645,162. (No model.)
T0 at whom, it may concave;
Be it known that I, ARTHUR IV. GLESSNER, a citizen of the United States, residing in Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Soft-Coal Furnaces, of which the following is a specification.
It is now quite usual to place in healingfurnaces designed for use with soft coal hollow rings extending around the top of the firepot and serving as a means through which heated air may be supplied to the top of the fire, so as to secure the combustion of the smoke and gases arisingfrom the fuel. These rings have heretofore been made either in one piece or in two halves, the dividing-line between which is a horizontal one. Either construction makes them expensive to manufacture, and they have been positioned in the furnace between the fire-pot and the dome and with the latter resting upon them, which makes it impossible to replace them except by disconnecting the air and smoke pipes and dismantling all of the furnace above them. As they are necessarily exposed upon the inner side to the most extreme heat, they are very liable to burn out on that side in ashort time and before the outer parts have been affected or in any way injured. Of course they are generally ruined when this happens and must be replaced at large expense. My endeavor in this invention is to reduce this burdensome expense as much as possible and also to so construct the ring as to render unnecessary any dismantling of the furnace in making changes or repairs.
The invention consists in the novel construction of the ring, as hereinafter fully set forth.
In the accompanying drawings, Figure l is a perspective of my improved ring, showing one of the inner sections thereof as detached and about to be positioned. Fig. 2 is a vertical section of the ring and adjacent parts of the furnace.
- In said drawings, A represents the fire-pot, and B the dome, of the furnace, and both may be of the ordinary construction. The gasring is inserted between the pot and the dome in the usual manner and is made in parts, as now to be explained. The outer part or halfcircle of the ring (shown at O) is cast separate from the inner part, and as it does not come in direct contact with the fire I make it in one piece. The duct or passage D through which the fresh air enters the ring, may also be madeintegralwiththisouter part. Around the bottom edge of the part 0 is a depending lip G, adapted to enter the annular groove A upon the top of the fire-pot, and around the top of the part 0 is a wide annular groove 0 adapted to receive not only the bottom edge of the dome, but also the downwardly and outwardly bent upper edge D of the sections D, which form the inner half or side of the ring.
The sections D are.short and uniform in shape and size, so that should one of them burn out or become injured, so as to destroy the integrity of the ring, it can be replaced without disturbing the other sections. Indeed, it is such a simple matter to remove one of these sections and to replace it with a fresh one that it can be done with the aid of a poker as the only tool and without putting out the fire. The sections are perforated, as
clearly shown, so as to admit the air to the fire, and are also shaped, as shown, so they will retain their position by gravity, the fire side D thereof being extended downward below the bottom of the turned-over edge D, which rests in the groove of the part 0 and is also bent outward slightly, so as to set against the fire-pot.
By the construction described I provide a gas-burner ring all portions whereof which are subjected to the direct action of the fire are readily removable without any necessity of even disturbing the parts which do not ordinarily burn out, and thereby save the user the greater portion of the expense to which he has heretofore been subjected both in the cost of the ring and in the expense attending its renewal or replacing.
I claim- 1. The combination in a heating stove or furnace of a fire-pot wall having a section of a joint about its upper edge, the wall of a combustion-chamber having a section of a joint about its lower edge, an interposed independent cast-metal ring between the firepot wall and the wall of the combustion-chamber having on its under edge a joint-section and upon its upper edge a j oint-section ,bulged outwardly between them to form a passage or chamber and adapted to connect the firepot Wall with the combustion-chamber wall, and separate or sectional plates provided with passages extending through them, applied to the inner face of said interposed section but not extending, upon the combustion-chamber wall or into the fire-pot, and providing an inner wall to the said passage or chamber and a protecting medium to the said interposed section.
2. In a heating stove or furnace the combination of the cast-metal fire-pot wall, the castmetal combustion-chainber wall, the castmetal wall intermediate, the combustion-
