APPARATUS FOR MANUFACTURING STEEL? SPECIFICATION forming part of Letters Patent No. 361,256, dated April 19, 1887.

tain new and useful Improvements in Apparatus for Manufacturing Steel; and I do hereby declare that the following is a full, clear, and

exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form part of this specification.

My invention relates to apparatus for manufacturing iron and steel; and its objects are, first, to'provide for easily maintaining a fluidtemperature of the mass during transit, and, second, to secure that end with simplicity of plant. I accomplish these aims by the means illustrated in the accompanying drawings, in which Figure 1 is an elevation of the converter andaccessories embodying the principles of my invention. Fig. 2 is a vertical section of the converter. Fig. 3 is an elevation of the platform capable of vertical reciprocation and adapted to hold the truck and appurtenances shown. Fig. 4 is a view of the handle by which the efflux of slag is controlled. Fig. 5

is a vertical section through the platform of the truck and cogged turn-table, showing their relative position. Fig. 5 shows aplan view of the truck. Fig. 6 is a detailfview of the valve which regulates the discharge of the slag; and Fig. 7 is a detail view of the under side of the platform, showing the sliding balland-socket joints operating in slots, whereby the vertical reciprocations are effected.

Similar designations indicate corresponding parts in all the views.

In practice it has been found that the use of the bottom section of a converter, to serve as a movable receptacle for the molten mass to and from the stationary portion of the converter, (besides its normal function), involves a loss of heat and consequent fluidity, which seriously impairs the successful execution of subsequent operations. therefore intended to supply a deficiency .in the apparatus shown in Patent No. 313,079, granted to me March 3, 1885, to .the end of obviating the objection noted.

- A 'B 0 represent the sections of my converter. Concentric with the sect-ion A is a This invention is Application filed May 7, 1855. Serial No. 164,652. (No model.)

hotair chamber, N, having removable covers 0, to permit of renewing'tuyeres Q. The section Bis keyed and luted to section A, and they normally rest together upon supports F F. The air-passage N is attached to the outer surface of section B, and connects the hot-blast pipe G with the chamber N. The section B is also provided with trunnions P P, rotating in bearingsF Fwhen so actuated by the gear wheel K, operated by an endless screw, K. On the other side, where the blast is admitted, a cold'water pipe, I, is provided to maintain an even temperature with that of the other trunnion. The section 0 is intended to be removably joined to B by keys and luting, for it is a feature of my invention that this section shall, besides its normal purpose, serve as a ladle to transport the fluid mass from the furnace to the converter. A cog-wheel, S, on the side of 0, when operated by a pinion to which power is transmitted by a bandwheel, H, tends to alter the inclination of the support D and the contained section 0 to pour the metal. The support D is secured upon the truck It", which, by means of the movable platform E, can receive section 0 from and restore it to section B. The truck R is recessed at R to permit of placing the cogged turn-table R and the operating-pinion R flush with its surface. An annular groove, R, is provided to accommodate the bolts R during rotation, and a socket or depression, R affords a bearing for the spindle R", on which the turntable revolves. The frame R being bolted to the turn-table Rt moves synchronously therewith and transmits theimparted motion to the supports D, thus horizontally varying the position of the section 0, so as to bring its spout M in alignment with a suitable discharge-receptacle.

When thesection G is in transitbetween the furnace and the stationary portion of the converter, a cover, 0, is provided to keep approximately a uniform temperature therein. A loop, X, serves to handle the same, and a hinged door, Y, permits inspection of the interior. Weighted levers L L, attached by a sliding ball-and-socket joint to the base of the platform E and .secured rigidly to the shafts.

T T, effect the reciprocations of the platform, the movement of the levers in an arc of a circle being caused by a pinion, U, on the shaft rco U, which derives its motion from gear-wheels T T on the shafts T T, that are actuated by a hand-wheel, V. M is an aperture, through which metal and slag are poured. V is a valve to control the effiux of slag from section 0, and it is operated by a handle, W", which is rigidly secured thereto. X X are platformguides.

The operation is as follows: The section 0 is run to the furnace by truck R. The molten metal is then charged. The cover 0 or its equivalent is then placed on the section. The

truck and contents are conveyed to the stationary portion of the converter. The cover 0 is removed. The section 0 is secured to section B by keys and luting, the hot blast turned on, and the converter alternately inverted and restored to secure homogeneity of the mass. The slag is drawn. The section 0 is disjoined and conveyed to the molds, where its contents are poured. Any remaining slag is dumped after the metal has been discharged.

I do not herein claim the process by which this apparatus is operated, as the same has been secured to me by Patent No. 347,913, granted on the 24th day of August, 1886.

Heretofore a sectional converter has been employed, whose lower portion could be conveyed to charge and discharge the metal, as shown in my patent of March 3, 1885, above referred to; but therein no provision was made for maintaining fluidity of the mass during transit.

I am also aware that a unitary converter has been patented, in which a semicircular plate is secured by bolts or clamps over the month of the same, as well to prevent the escape of gases from the mass as to obviate atmospheric access during'transit of the converter. My invention is solely addressed, however, to the maintenance of a fluid-temperature in sectional converters during transit.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent of the United States, is-

The sections A B, normally joined, the latter having central supporting-trunnions, P P, one of which is hollow to admit an air-current, and the other having a gear-wheel, K, to cause vertical rotation, bearings F F and supports F F, in combination with the section 0, provided with trunnions, the truck R, provided with a hand-wheel, R, the supports D, the platform E, and the means for raising and lowering the platform, as described, the whole cooperating for the purpose 'set forth.

In testimony that I claim the foregoingas my own' I- affix my signature in presence of two witnesses.
