UNITED STATESv PATENT (DEEIcEt RICHARD -PEARCE, OF BLACK HAWK, COLORADO TERRITORY.
IMPROVEMENT IN REVERBERATORV FURNACES..
Specification forming part of Letters Patent No. -176,994, dated May2, 1876 application filed April 15,1875.
To all whom it may concern:
Beit known that I, RICHARD PEARcE, of Black Hawk, Gilpin county, Colorado Territory, have invented an Improvement in Reverberatory Furnaces; and I do hereby declare the following description and accompanying drawings are suiicient to enable any person skilled in the art or science to which it most nearly appertans to make and use myl said invention or improvement Withoutfurther invention or experiment.
The object of my invention is to provide certain improvements in reverberatory furnaces, and it is more especially adapted for use in such furnaces as burn wood as a fuel, and as a large grate-surface has been usedy heretofore, much of the products of the combustion would find its way to the stack or chimney vunconsumed, and therefore wasted@ My improvement contemplates a more per-l feet combustion ,of the fuel, and a consequent economy of heat; and it consists in a novell construction of the fire-place, together with the employment of openings at certain points, whereby air is admitted, so that sufficient oxygen will be supplied to insure a complete combustion.
Referringto the accompanying drawings for a more complete explanation of my invention, Figure l is a perspective view of my furnace. Fig. 2 is a transverse section taken through the fireplace.
A is the body of a reverberatory furnace. B is the stack or chimney, and C is the liue leading to the stack. D is the lire-place, and E is the grate upon which the wood is placed. In order to reduce the grate-surface Without making the body ofthe lire-place too small, I make the walls of the tire-place incliniu g from a point a short distance above the gratedown to its surface, where, it will be seen, the distance becomes very much narrowed. T hefuel l is, consequently, not spread over so large a surface as in other fire-places.
The gases of combustion pass bridge-wall F, and are deliected upon the hearth of the furnace and its contents in the usual manner, but an insufficiency of oxygen causes a considerable loss of heat from the incomplete combustion.
In order to supply the necessary amount of oxygen to make the combustion perfect, I perforate the -top or roof of the furnace with a series of openings, g g, just above and behind the bridge-wall, and also extending a short distance along the sides, as shown.` Through these openings the air passes, and, meeting the flame as it passes over the bridge-wall, a sufficient quantity of oxygen will be supplied to completely consume all the gases and make amost intense heat.
I am aware that atmospheric passage-ways have been constructed through the arch over f the tire-room and bridge-wall, for the purpose of passing broad thin currents of air heated `in passing through the wall, and discharge at a line over, or nearly over, the rear side ofthe bridge Wall, downwardly and diagonally across the current of the gaseous products of combustion; but this is not my invention.
A Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-
rlhe furnace A, having the roof perforated with openings g g over and behind the bridgewall, and arranged along the sides, substantially as-and for the purpose described.
Inwitness whereof I hereunto set my hand and seal.
RICHARD PEARCE. lL.
