MACH'INE FOR 'BLOOMING IRON.

SPECIFICATION forming part of Letters Patent No. 306,157, dated October 7, 1884.

Application filed December 13, 1883.

T all whom it may concern Be it known that I, JAMES J. JOHNSTON, of Golurnbiana, in the county of Oolumbiana and State of Ohio, have invented a certain new and useful Improvementin Machines for Blooming Iron; 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 to thereon.

My invention has for its object the blooming of balls of iron, usually called puddled balls, and accomplishing the same without liability of tearing them into two or more fragr5 ments, and without danger of breaking the bloomingmachine when subjected to undue strain while blooming balls of unusual size and of different degrees of plasticity and adhesion.

The nature of my invention consists in the combination of a table curvilineal on its upper side andaplano-concave plate, the former susceptible of a vertical'and the latter of a reciprocating motion, and their operating mechanism, all of which will hereinafter more fully and at large appear.

To enable others skilled in the art with which my invention is most nearly connected to make and use it, I will proceed to describe its construction.

' In the accompanying drawings, which form part of this specification, Figure 1 is a side elevation representing a part of the machine in longitudinal section at line 00 a in Fig. 8.

3 5 Fig. 2 is a side elevation of the machine. Fig.

3 is an end elevation representing a part of the machine in vertical transverse section. Fig. 4 is an enlarged side view of a part of the machine. Fig. 5 is a horizontal section of a part of the machine at line y of Fig. 1.

Reference being had to the accompanying drawings, A represents the frame of the ma chine, and consists of heavy east-iron sides B, each having adoor, O, andtheinner wall of each side furnished with a channel or way, D, for rollers E, the axes F of which are secured in or to the plano-concave plate G. The end H and top I of the frame A are also constructed (No model.)

of cast-iron and made heavy and strong and The frame A bolted firmly to the sides 13. and steam-cylinder J should be bolted down upon bed-timbers or masonry capable of withstanding heavy j ar and strain. The steam cylinder J is of the ordinary construction employed for lifting, such as is used for operating asteamhammer, the construction of which is well known,and need nottherefore be further described. The curvilineal table K is provided with V-shaped grooves L, in which guides M, corresponding to the form of the 6c grooves L, are placed, said guides M being constructed on or attached to the inner walls of the sides B of the frame. To the under side of the table K is attached the upper end of the piston N of the steam-cylinder J which cyl- 6 5 inder and piston move the table K vertically at the will of the operator, who controls the movement through the medium of a lever, O, which operates the steam-valve I of the steamcylinder J, the guides M in grooves L guiding the table K in its vertical movements. The plano-concave plate G is supported upon rollers E, which turn on axes F, the track of the rollers being the channels or ways D. To one end of the plane-concave plate G is attached an operating-rod, Q, having slide R, which moves in guides S, and to which slideis pivoted at T a pitman, U, which may be connected to the crank of an engine or other operating machinery. The upper and working face of the curvilineal table K and the under and working face of the piano-concave plate G are corrugated, as shown in Fig. 1 of the drawings.

The skilled mechanic will readily understand the construction of my improvement in 8 5 machines for blooming iron from the foregoing description and by reference to the accompanying drawings. I will therefore proceed to describe briefly the operation, which is as follows: The curvilineal table K is lowered 0 to its lowest point by means of the piston and steam-cylinder and one of the doors 0 opened. The ball of puddled iron is then placed upon the table K, the door closed, and the table elevated by the means hereinbefore described, 5 which will bring the ball up against the pianoing motion imparted to it through the medium upper side and a plano-concave p1ate,the for of the operating mechanism, will compress iner susceptible of a vertical and the latter of and roll the ball into an elongated bloom. a reciprocating motion, and theiroperating 5 The table K is then lowered and the door 0 mechanism, substantially as herein described, I 5

opened and the bloom removed from the machine. It is then ready for the reception of another ball of iron. XVitnesses:
