CUPOLA-FURNACE.
SPECIFICATION forming part of Letters Patent No. 573,825, dated December 22, 1896. Application filed May 27,1896. Serial No. 593,330. on model.)
To all whom it may concern:
Be it known that I, JEROME BONAPARTE Mm GILL, a citizen of the United States, residing at Moline, in the county of Rock Island and State of Illinois, have invented certain new and use ful Improvements in Oupola-Furnaces; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it ap- IO pertains to make and use the same.
My invention has relation to improvements in the construction of cupola-furnaces, and more particularly to that class of furnaces having a circular air-chamber from which the blast is admitted to the cupola through a series of openings arranged radially around it; and the object is to effect a better and more rapid combustion of the fuel and a more rapid melting of the metal, thus making a saving in the amount of fuel consumed and a saving in the time occupied in taking off a heat.
To these ends the novelty'consists in the construction, combination, and arrangement of the same, as will be hereinafter more fully 2 5 described, and particularly pointed out in the claims.
In the accompanying drawings the same letters of reference indicate the same parts of the invention.
0 Figure 1 is a perspective View of the lower end of a cupola embodying my invention, with a portion of the shell and lining broken away to show the interior. Fig. 2 is a longitudinal section on the dotted line a: a; of Fig.
3 5 1, and Fig. 3 is a perspective view of one of the recessed fire-bricks.
A is the shell of the cupola, and B B the regular fire-bricks forming the usual lining.
O O are the recessed fire-bricks and are of novel construction, being sector-shaped in horizontal section, preferably concave on their inner sides I) and convex 011 their outer sides I), while the tops a and the bottoms a form true horizontal planes parallel with each other and with the layers of the regular bricks B 13, above and below them.
The outer convex side 6 of each brick O is formed with a recess 0 and its sector-shaped sides 0 c with a recess 0 so that when a circle of these bricks O is laid in the same hori zontal plane inside the shell A on top of a layer of the ordinary bricks B B the series of recesses o in the bricks O form a continuous annular air-space E entirely around the outside of the lower portion of the bricks O and the inside of the shell A, and the recesses c on the sector-shaped sides join the similar recesses 011 the contiguous sector-shaped sides of the adjoining bricks in the same horizontal layer and form a series of radial air-passages e, connecting the annular air-spaceE with the interior of the cupola.
G is the usual notch for drawing off the molten metal,and l-I represents the slag-spout.
The blast-pipe F communicates at two opposite points with the annular air-space E, so that it may in turn feed the air equally through all the annular series of radial airpassages 6, this being the essential point, as the circulation of air around the annular space E and through the passages e not only keeps the brick at a lower temperature, thereby preventing their burning out and also preventing the material from adhering to them, but also produces a better and more rapid combustion of the fuel and a more rapid reduction of the contents of the cupola, thus making a saving in the amount of fuel consumed and greatly lessening the time required to take off a heat. Anotherimportant advan 8o tage is that it very materially increases the capacity of the cupola, as I have found in actual practice that with a cupola lined in the ordinary manner it requires about two and a half hours to take off a heat of six tons, while with the same cupola fitted up according to iny improvement a heat of nine tons can be taken off in about two hours.
Having thus described my invention, what I claim as new and useful, and desire to secure 9 by Letters Patent, is-
1. As a new article of manufacture, abrick for cupolas comprising the brick O formed with the parallel top and bottom a a, its convex outside 1) formed with a recess 0 and its sector-shaped sides 0 formed with recesses cisubstantially as and for the purpose set forth.
2. A cupola comprising the shell A, and a series of sector-shaped bricks O provided with I00 rccesses c and c laid in the same circular In testimony whereof I hereunto affix my horizontal plaue,t0 form an annular airspace signature in presence of two Witnesses.
E between said shell and the bricks O and an annular series of air-passages con neeting JEROME BONAPARTE MAGILL' said air-space E with the interior of the cu- Vitnesses:
pola, substantially as and for the purpose set JOHN GOODMANSON,
forth. HENRY 0. FIRST.
