GEORGE- HORATIO CHICK, OF KANSAS CITY, MISSOURI.`
MUFFLE-FURNACE FOR DESULPHURIZING ORES.
SPECIFICATION forming part of Letters Patent No. 434,502, dated August 19, 1890.
Application filed December 27, 1889. Serial No. 335,099. (No model.)
To all whom it may concern:
Be it known that LGEORGE HoRArro CHICK, of Kansas City, Jackson county, Missouri, have invented certain new and useful Improvements in Munic-Furnaces for Desniphurizing Ores, of which the following is a full, clear, and exact description, reference being had t0 the accompanying drawings, forming a part hereof.
My invention relates to improvements in munie-furnaces for desulphurizing ores; and it consists in the novel construction and arrangements hereinafter set forth and described.
In the drawings which illustrate the manner of carrying out my invention, Figure 1 is a perspective view of my furnace, showing the arches, iues, duc., in dotted lines. Fig. 2 is a central longitudinal section through the same. Fig. 3 is a sectional plan view taken on line tc of Fig. 2. Fig. 4 is a vertical crosssection taken on line y y of Fig. 2; and Fig. 5 is a rear view, partly broken away, showing the openingin which the receptacle is placed for catching the ores when the discharge is made.
Referring to the drawings by letter, A represents a brick furnace constructed in the manner illustrated and provided at its front with a smoke-stack B.
C is a feed-chute constructed directly behind the smoke-stack leading to thedesulphurizing munie-chamber H. (More clearly illustrated in Fig. 2.)
D and D are suitable iron braces properly bolted to the sides of said furnace by rodsd and d. These rods pass entirely through the brick-work of the furnace and serve to hold it firmly together.
E are rods running longitudinally through the furnace, which serve the same purpose as rods d and d.
F is the ash-pit, built in the ordinary inanner under the fire-boX, said tire-box being provided with suitable grates f and tile f.
H is a desulphurizing mutile-chamber in which the ores are placed. At the rear of said chamber H is an air-chamber S, provided with a cap T, which may be removed for admitting air into said furnace when found desirable.
I is an arched chamber built directly over the desulphurizing-chamber H, through which the ablast passes from the fire-box G, said chambers Hand I being connected by vents WV, which allow the accumulating gases to escape from the desulphurizing chamber H through arched chamber I, and from thence through flue K up through smoke-stack B. Vhen the reis started in fire-box G, the blast finds an outlet through flue M, as shown in dotted lines in Fig. l. This ue M :is at the rear of said fire-box G. Theblast thus passes forward parallel with the desulphurizingchamber H through ii'ue J', and is carried over front of said chamber through flue O, as illustrated in Figs. l and 2. The blast then passes back along another flue J, which runs parallel with chamber H, and then through passage N into arched chamber I, where it circulates over the top of desulphur- `izingchamber H, and then around iiue K into smoke-stack B, this latter passage being more clearly illustrated in Fig. 3. The lues J and J which run parallel with desulphurizingchamber H, are constructed inthe manner illustrated in Fig. 4, thus giving greater heating-surface to said chamber.
g is a tile door, which closes the front of tire-box G, said tile door g being secured and held in position by the angle metallic bars or guides g', which allow said tile g to slide laterally when fire-box G is to be replenished with fire. h is a similar tile door, which operates vertically in front ot' chamberH. This door h is drawn out of position by suitable wire rods t', which are secured in the lugs m', said wires and t" being operated by overhead levers constructed in anysuitable manner, the depending guide-rods m serving to keep the door vertical when sliding.
P is a vertically-moving tile secured at the rear of desulphurizing-chamber H. This tile operates in the slot P and is for the purpose of closing the rear of said chamber H, and is secured in such a manner that it may be raised when it is necessary to make a discharge, thus allowing the desulphurizing ores to pass from chamber H through the discharge-passage R into the opening U at the rear of said furnace. Said'tile P is operated by a wire in the same manner as the front ICO ' eating with the ire-chamber,a supplemental chamberlocatedabove themuftle-chamberand in communication with said chamber and also with the passages described, and a stack in communication with the supplemental chamber, substantially as described.
2. An ore-roasting furnace having a roasting-chamber H, a fire-chamber G beneath the same, the passages M, J', O, J, and N, surrounding the heating-chamber, the supplemental chamber I, located above the heatingchamber and in communication with the same by means of the passages XV, the supplemental chamber being in communication with the fire-chamber by means of the passages M, J O, J, and N, the stack B, passage K, connecting the stack and chamber I, the feedchute C, and discharge-opening R and door P, for controlling said opening, substantially as shown and described.
In testimony whereof I aflix my signature in presence of two Witnesses.
