H. L. CHARLES. REVERBERATORY FURNACE.
No. 599,597. Patented Feb. 22, 1898.

SPECIFICATION forming part of Letters Patent No. 599,597, dated February 22, 1898.
. Application filed June 26, 1896.
To all whom, it may concern.-
Be it known that I, HENRY LEWIs CHARLES, of Butte, in the county of Silver Bow and State of Montana, have invented certain new and useful Improvements in Reverberatory Furnaces, of which the following is a full, clear, and exact description.
The invention relates to furnaces for smelting and refining copper and other fusible ores; and its object is to provide certain new and useful improvements in reverberatory furnaces whereby the gases are carried off in a verysimple manner and the cost of the fuel and the Working of the furnace are reduced to a minimum, and at the same time the working of the furnace is completely under the control of the operator.
The invention consists principally of a hearth provided with a bridge at the flue end and having a throat leading to the flue.
The invention also consists of certain parts and details and combinations of the same, as will be fully described hereinafter and then pointed out in the claim.
Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar, characters of reference indicate corresponding parts in all the figures.
Figure 1 is a sectional side elevation of the improvement. Fig. 2 is a plan view of the same with parts broken out, and Fig. 3 is a transverse section of the same on the line 3 3 of Fig. 1.
The improved furnace is provided with a hearth A, provided at one end with the usual bridge B, over which pass the flame and gases from the fuel burning in the fire-box O of any approved construction.
The end of the hearth A,which is connected with the stack-flue, has a bridge D, forming the lower side of the throat or neck E, opening into the flue F, which is curved downwardly and connected with a transverse passage F, leading to the stack, it being understood that anumber of furnaces are connected with the said transverse passage. The top of the throat E is formed by an arch Gr, having openings or slots, one end of the arch abut- Serial No. 597,058. (No model.)
ting against the arched top H of the hearth, the said top H being provided with the usual feed openings for introducing the ore onto the hearth. These openings in the arch 0 may be closed at will by placing bricks or other objects over them or may be left uncovered, as the requirements may dictate. In this way air may be admitted to the flue beyond the furnace, checking the effect of the draft in the fire,whenever this is desired, and at the same time cooling off the arch O and the flue. This protects the flue and arch in a measure and thus makes them last longer and reduces the cost of maintenance. The form of flue connection with the stack is also more direct, and consequently less of the force of the draft is lost by friction in the'flues.
The wearing or burning effect of the blast is most severe upon the arch O and bridge D. The furnace is however so constructed that these parts are accessible for repairs without cooling off the furnace as much as is necessary with the ordinary furnace, and consequently less heat is wasted during repairs; also, by the construction the repairs are needed less often. Altogether this results in considerable saving.
Into the flue F, next to the throat E, discharges a steam-nozzle I, connected with a suitable source of steam-supply to insure a forced draft of the furnace, as the steam issuing through the said nozzle passes 'down the flue F, and thereby creates asuction in the throat E and hearth to insure a proper draft for the furnace. This may be dispensed with in cases where the natural draft is sufficient or where other means for securing a forced draft are provided.
In the bridge D is arranged a hollow transversely-extending casing J ,serving to stren then and preserve the bridge.
By having a perfect draft under the control of the operator a poorer grade of coal can be used, especially as the flue F makes a direct connection by the throat E between the passage F and the top of the hearth A. It is understood that the discharge of the matte and 5 slag takes place at the sides of the furnace.
Having thus described my invention, I claim as new and desire to secure by Letters Patent- A reverberatory furnace having a hearth, a flue curved downward from one end of the hearth, a bridge located between the flue and the hearth, and an arch built over the bridge and running transversely with reference to the hearth, the arch having perforations running vertically through the arch and opening 10 at the top of the furnace whereby to regulate the draft passing over the bridge.
