UNITED STATES PATENT QEEICE.
vGALEB MARSHALL, OF PHILADELPHIA, PENNSYLVANIA.
IMPROVEMENT IN FURNACES FOR HEATING AND ANNEALING SHEET METAL. &c.
Specicatlon forming part of Letters Patent No. 154,334, dated August 25K, 1874; application filed July 22, 1874.
To all whom it may concern;
Be it known that I, CALEB MARSHALL, of the city of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain' new and useful Improvements in Metallurgie Furnace for Heating Sheet Metal; and I do hereby declare thatthe following is al full, clear, and exact description thereof, which will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specication, in which'- Figure l shows a longitudinal vertical section, Fig. 2 an end view, and Fig. 3 a crosssection inthe line a: w of Fig. 1.
In patent No. 114,956, issued to me, dated May 16, 1871, I have described a process for removing scale from iron, and otherwise treating it during the operations of annealing, fmishing, and coating. 4
In carrying on the several operations `named in said patent, a heating-furnace is required. The object of my present invention is to provide anew and improved furnace for that purpose.
The metal being generally in the form of sheets, and requiring the same uniform treatment in all parts, it is necessary that the heat be evenly distributed, and regulated at will to any required degree. The heating chamber must bekept as free as possible from lame,s1noke, dust, and sulphur, and should, in no part, become too highly heated. The accomplishment of these ends is the result of my invention.
The following description will enable others skilled in the art to construct my invention, and, by reference to the specification of my former patent named above, to use it in carrying out the improvements described in said patent in a more efficient manner. The furnace is also applicable in carrying out other processes and operations, such as annealing,
- tempering, coating metals, enameling, and the like.
In the drawings, A is the hre-chamber, covered by a perforated arch, B, above which is the chamber or oven C, in which is placed ordinary lifting or working door, such as.
used in heating andl other furnaces, and the lower, g g, suitable doors for charging fuel into the fire-chamber. Grate-bars h h h extend the entire length ofthe furnace, but a lire-box at each end, or even a fire-box at only one end, with suitable arrangement of ues and dampers, so as to distribute the heat, would answer. I prefer, however, the arrange. ment shown.
The perforations la k in the arch of the firechamber permit the products of combustion to enter the oven, and distribute them evenly;- and the interposition of the perforated arch between the fire-chamber and the oven prevents any excess of temperature at any part which would injure the articles to be heated.
On the floor of the oven are placed supports t t, made preferably of wrought-iron, on which rests the sheet-iron or other article, as shown at fw w. Beneath the gratebar is the ashpit. P.
The arrangement shown gives a free coinbustion of the fuel, an even distribution of the heat in the oven, and easy means of controlling the temperature at all times. If the oven is too hot in either end, a proper adjustment of the damper will equalize it, and, by closing or opening them, the heat is controlled. A
Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s
l. A furnace for heating metal plates, sheetiron, and other metallic articles, pro-- Yvided with a ire-chamber and a heatingoven with a perforated arch between, arranged so as to operate substantially as described.
2. The combination of the re chamber7 In testimony that I claim the foregoing as the perforated arch, and heating chamber; my ownjnventionl'afx my signature. in pres'- having ues F E and dempers f f at each ence of two witnesses.
end. GALEB MARSHALL.

with a perforated floor, supports t t, and ues ALFRED MARSHALL,
