SQUIRE M. FALES, OF BALTIMORE, MARYLAND.

IMPROVED FURNACEFOR SMELTING IRON.

Specification forming part'of Letters Patent No. 22,861, dated February 8, 1859; Reissue No. S35, dated October 18, 1859.

To all whom it may concern.- 'K

Beit known that I, SQUIRE M. FALES, of the city and. county of Baltimore, and State of Maryland, have invented a new and Improved Mode of Constructing Furnaces for Melting and Refining Gast-Iron, and also Ores of Various Kinds; and I do hereby declare that the following is 'a full, clear, and exact description thereof, reference being had to the accompanying drawing, and to the letters anneXed to the different parts thereof.

The nature of my invention consists, iirst, in the combination, with the cone ofa furnace, of one or more arched recesses or chambers; second, in the combination of an opening with the crown of the arch or recess; third, inthe combination, with the arch or recess and opening in the crown of the same, of a movable tymp to be applied to the outer ends of the arched recesses or chambers, instead of the permanent tymp now in use, which movable tvmp` is kept in place by a cross-bar that can be removed at pleasure.

By the first feature of my invention the blast is allowed a chance to expand laterally or circulate before it rises in the cone of the furnace, instead of being compelled to pass, as heretofore, directly upward. Thus having the blast circulate I have found in practice causes the substances being melted to have new qualities imparted to them, and they consequently are converted into a better description of metal, and that, too, Witha much less consumption of fuel.

By the second feature of my invention provision is made for the introduction, from the outside of this character of furnaces, of any iiues necessary to make the furnace work perfectly; and by the third feature facilities for repairing or cleansing thefurnace are afforded.

To enable others skilled in the art to make Y a nd use my invention I will proceed to describe the metal before it reenters the cone, instead of being forced immediately upward, as in the ordinary mode.

B B represent the movable tymp,by which the external openings of the arch are closed, and which can be removed at pleasure for the purpose of cleaningor repairing the furnace, instead of the permanent tymp fixed, as at present, in the sides of the furnace.

C denotes the dam-stone upon which they tymp rests.

D denotes the opening through which the cinders escape.

E represents the notch or outlet for the are introduced, instead of being thrown, as at present, into the cone. y

K represents the bottom of the furnace, and L denotes the cone.

It will be seen at a glance that the three improvements herein described can beintroduced at will into any of the furnaces now in use.

Y'Vhat I claim as my invention, and desire to secure by this Reissue, is-

1. The combination, with the cone of a furnace, of one or more arched recesses or chambers,vA A, substantially as and for the pur poses set forth.

2. The combination of an opening, I, with the crown of the arch A, substantially as and for the purposes set forth.

3. The combination, with the arch-recess A.

opening I in the crown ofthe same, ofa movable tymp, B B,t o be applied to the outer ends of the arched recesses or chambers A A, instead of the permanent tymp now in use, which movable tymp is kept in place by a cross-bar that can be removed at pleasure, substantially as and for the purposes set forth.
