WILLIAM BRUCKNER, OF SAN FRANCISCO, CALIFORNIA.
IMPROVEMENT IN FURNACES FOR DESULPHURIZING ORES.
Specification forming part of Letters Patent No. 65,538, dated June 11, 1867.
To all whom it may concern.-
Be it known that I, WILLIAM BRI'JQKNER, of the city and county of San Francisco, State of California, have invented certain new and useful Improvements in Cylindrical Furnaces for the uniform mixing and roasting of ores and other substances; and I do hereby declare the following description and accompanying drawings are sufficient to enable any person skilled in the art or science to which it most nearly appertains to make and use my said invention or improvements without further invention or experiment.
The nature of my invention relates to or consists of an inclined partition-wall, passing longitudinally through the cylinder, in shape a rhomb or deviating square, the ends being obtuse angles.
In the drawings, Figure 1 represents a front view; Fig. 2, a longitudinal projection; Figs. 3 and 4, end views.
A represents a suitable frame or stand with friction-rollers, upon which is placed the cylinder B. I construct my cylinder in the usual way, of iron or other material, equal in its diameter, having a partition-wall, D, running longitudinally through it. This partition I construct in one continuous piece, in the form of a rhomb or deviating square, whose ends are obtuse angles, to be withdrawn by grooves upon each side of the cylinder, made when lining it with fire-brick or other material or my partition may be made in diagonal sections, to be withdrawn piece by piece, as oocasion may require, as when eaten or decomposed by the action of the sulphur or heat, through longitudinal holes made in the side of the cylinder. In either case I cover my partition with fire-proof material, so as not to expose the iron to the decomposing effects of the material to be treated. My partition may also be constructed of fire-proof material, entirely with double-concave walls, (shown in end view, Fig. 4,) with or without the flat iron partition between. I have not yet determined which is the best manner for constructing it, but prefer, so far as I have experimented, to use the flat surfaces, covered at all points with the fire-proof material.
I place my partition in the cylinder at an angle of inclination of from ten to fifteen degrees, or so as to insure a constant passing and repassing, as well as a continuous and uniform mixing of the material to be treated from end to end over each surface of the said partition; yet, the sharper the angle of inclination, the sooner the circuit of the material is obtained. Charging and discharging holes may be placed at any point in the cylinder opposite the surface of the partition to insure ready means for this purpose.
The material to be treated is placed in the cylinder and the fire introduced in the usual way, and the cylinder slowly revolved-say, at the rate of two revolutions per minute-until the whole is sufliciently roasted.
It is intended by this arrangement that any material can be roasted; but it is more especially adapted to roasting ores containing metals, and it is believed that a greater surface is furnished for oxidization and heating than is ordinarily found in furnaces of the same dimensions, and at much less expense, and with greater ease, as the constant passing and repassing of the particles to be treated through the cylinder and over the partition, onaccount of its peculiar construction and position, insure a constant distribution of the material.
I am well aware that cylinders and furnaces have been constructed for roasting ores, with curved arms or stirrers and flanges; but I am not aware of there having been any furnaces constructed with a continuous longitudinal or inclined partition like my own.
I therefore claim as my invention, and desire to secure the same by Letters Patent The inclined partition I) in the form of a deviating square, or any other shape, placed at any inclination or angle to in sure a constant passing around it of the material to be treated, said partition to be constructed of iron plates, in sections or as a whole, and soldered with fire-proof material, with surfaces flat or dou- -ble concave, substantially as described, and for the purposes set forth.
In witness whereof I have hereunto set my hand and seal.
WILLIAM BRUCKNER. Witnesses:
O. W. M. SMITH, JOHN REYNOLDS.
