Letters Patent No. 94,286, dated August 31, 1869.

IMPROVE!) APPARATUS FOR TH MANUFACTURE PIGj-BLOOM.

The Schedule referred to :ln these Letters Patent and making part of the same.

Be it known that I, JOHN Corne, of Allegheny City, 1n the county of Allegheny, and State of Penu- Sylvania, have invented anew and improved Iron- Manufacturing Apparatus; and I do hereby declare that the following is a full, clear, and exact description thereof', which will enable others tskilled in the art to make and use the same, reference beipghad to the accompanyingdrawing, forming part of this specification.

- This invention relates to an improved apparatus, to be used iu'iron-smelting and refining establishments, for receiving the molten metal from the furnaces and moulding it into blooms, pigs, orslabs, as required, and delivering it when suliiciently cooled.

And the invention consists in the combination and arrangement of the parts of the apparatus, as'will be hereinafter more fully described.

Figure 1 represents a plan view of my improved apparatus, with a part of the moulds or receivers turned over, as in discharging the pigs or slabs.

Figure2 represents a sectional elevation of' the same, taken on the line a: z of iig. 1.

Similar letters of reference indicate corresponding arts. p A represents a circular metallic table, having a large central Opening, arranged to revolve horizontally upon balls B, on a circular-grooved stand G, the bottom of the said table being also grooved to rest on the balls.

A circular ange, D, projects downward from the table, inside of the stand, and is toothed at the bot-' tomthe teeth 'gearing with a driving-pinion, E, which imparts the motion. These teeth may be either arranged, as shown, to receive motion from a Ypinion working in a vertical plane, or they may be arranged t0 gear with a wheel working horizontally from a vel'- iical shaft.

The table may also bc arranged to work on conical radial rollers, if preferred, instead of the balls B.

F represents a hoop or band cl'iron, attached to the outside of the table A, and projecting below the top ofthe stand C, which, together with the inner-projecting flange l), serves 'to prevent the molten metal, which may escape between the boxes or moulds, and run down upon the table, from getting into the groove of the stand, or upon the balls; they also prevent, in like manner, other matter from entrance to the groove.

G represents moulds or receiving-boxes, placed radially on the top oi' -the table A, and shaped so that the sides Iit together as closely as may be conveniently done.

.They may be. made of iron, or any other suitable substance, and shaped to give to the metal which iiows therein any required form, as pigs, blooms, or slabs;

they may also be divided intotwo .or more compartments, if preferred.

These moulds are jointed, at their outer ends, to bolts H, running diagonally through the table A, to the inside, where they are connected to spring-supports I, for the inner ends of the moulds, consisting of metallic plates, rising vertically'from'the inside of the table, and bent over near the upper ends, so that the said ends rest in the corner of an annular recess in the upper face of the table, as shown at K.

.These bent ends press the topmost parts, whereon the moulds rest, outward, slightly from the face of the table, and produce a springing action against the nuts L.

Keys may be used, instead of the nuts, for holding the bolts, if preferred. s a

The bottoms of the moulds are provided with bevelled studs M, "which, when the said'moulds are thrown back, after dumping, strike against the sides of the rounded or bevelled tops of the spring-supports I, and thereby relieve thesaid moulds from the severe shocks that `would occur in falling upon rigid supports.

The said moulds are also provided with other projections, N, to facilitate dumping them, by a bar- `placed under them, and resting on the top of the sup'- ports I, for a fulcrum, and operated by the attendant standing within the circle of the rotatingV table.

rlhe tops of the supports I are recessed, as shown at O.

Y lo prevent the metal .from ilowing down between the boxes upon the carriage or table, I provide the Tashaped guards, shown at l?, `to be placed between the moulds, so that the bent flanges thereof will lap .over the adjacent edges of the moulds.

The apparatus, thus'constructed, is. so placed, rela- At the"discharging-place, a curvedrail, It, is sov placed that the-upper edges 4S of the outer ends of l the moulds will strike thereon with force, and dislodge vthe metal, when of such a nature as to stick in themoulds.

This apparatus is designed more especially for use in such refiningfurnaces as are used in the direct production of wrought-iron from cast-iron, by a rapid process of decarbonization, by lthe use of oxides, but is applicable to other furnaces.

I do not claim a VInoving or revolving table,with moulds or boxes, in combination with spouts, so as to form pig-blooms of molten metal and oxides, or other materials.

Havingthus described my invention, i

What I claim as new, and desire to secure by Let- 3. The flange D lund hoop E, combined with the ters Patent, istable A and stand G,- substantiallly as specified.

1. The moulds, hinged at the outer ends to the bolts 4, The combination, with the moulds Gr, of the Il'- H, connected to the spring-'supports I and all comslxaped guards, substantially as specified.

bined with the table A, and arranged as specified. 'JOHN OOYNE.

2. The arrangement of the bevelled projections M, Witnesses: i l on the moulds, and the springupports, substantially J AMES G. STEPHENS,

as specified.
