DAVID W. BRUNTON, OF SILVER PEAK, NEVADA.
IMPROVEMENT IN REVOLVING ORE-ROASTERS.
Specification forming part of Letters Patent No. 215,877, dated May 27, 1879; application filed September 23, 1878.
To all whom it may concern:
Be it known that I, DAVID W. BRUNTON, of Silver Peak, Esmeralda county, State of Nevada, have invented an Improvement in Ore-Roasting Furnaces; and I do hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawings.
My invention relates to an improvement in rotary ore-furnaces; and it consists in a set of flanged conical rings in combination with and retaining the throat-linin g.
Referring to the accompanying drawings for a more complete explanation of my invention, Figure 1 is a longitudinal section. Fig. 2 is a transverse section.
Let A represent a roasting-cylinder for roasting gold, silver, and copper ores. The internal diameter of this cylinder is greater at the center than it is at the two ends, as shown. The discharging-door A is situated in the center or broadest part of the furnace.
The cylinder is intended to revolve, and for this purpose the traveling rings B are secured on the outer surface of the cylinder, and rest on the truck-wheels D, on which the cylinder revolves.
To give the cylinder motion, power is applied to the pulley L on the shaftL, which thus revolves the actuating-screw E on the same shaft. This actuating-screw meshes with the wormwheel J on the shaft J and as the screw-wheel I is on said shaft J it is also revolved. This spur-wheel I engages with the cogs on the gear-wheel F on the outside of "the cylinder, the cylinder thus being rotated.
G O are self-keyed fire-brick, held in place by the wedge-shaped rings or clamps G G, which are in turn held in place by the setscrews H H. To remove the throat-brick, the set-screws may be unscrewed and the rings G G removed, when the bricks may be separately removed. While the rings G G are in position it is impossible for the throat-lining to get out of place.
I am aware that rotary ore-roastin g furnaces have heretofore beenmadewith their greatest diameters at their longitudinal center, and hence I do not claim any such furnace.
Heretofore one of the greatest difficulties in operating cylinders has been to keep the throatlining in position.
Withthe arrangement shown in the drawings and herein described, it is impossible for a brick to get out of place. The wedge-shaped cast-iron ring is held in place by the set-screws, and is put in after the throat -brick are in place.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
The flanged conical retaining-rings G G, in combination with the throat-lining O U, for re taining it in position, as set forth.
In witness whereof I have hereunto set my hand this 20th day of August, 1878.
DAVID W. BRUNTON.
