Application tiled January 6,1897. Serial No. 618,122. (No specimens.)

To @ZZ whom, t may concern.-

Be it known that I, LON LEVY, a citizen of the Republic of France, residing in Paris, France, have invented certain new and useful Improvements in Processes of Pouring Metal Ingots, of which the following is a specification.

This invention relates to the process of pou ring steel or other metal to form ingots.

Part of the cavities produced in forging large steel ingots result from the fact that during the pouring of the metal there is produced at the surface a solid crust,lwhich is at times covered by liquid metal without becoming fused again, and this chiefly at the sides and angles. This phenomenon is marked Vto a still greater extent when the steel contains certain metals-chromium, nickel, dac. In order to obviate this defect, I have devised a method of pouring in such a way as to cause the jet to reach all parts of the surface of the ingot. For this purpose I employ the arrangement shown in the accompanying drawings.

Figure l is a vertical transverse section. Fig. 2 is a vertical longitudinal mid-section. Fig. 3 is a plan. Fig. Il is a front elevation viewed in the same direction as Fig. 1. Fig. 5 is a partial plan of Fig. 4. Fig. 6 includes a fragmentary enlargement of the extreme left-hand end of Fig. 4E and beneath it a plan of the same parts shown in this enlarged fragment.

An intermediate ladle C of small size, 3rovided with an outflow-hole B, is suspended under the ladle P, which receives the charge of metal from the furnace and which has an outflow-hole A, directing the metal into the intermediate ladle C.

The small ladle C, mounted on trunnions O, hung from hangers ff and steadied by ties e g, can by means of a hand-lever Z be oscillated, which by inclining the jet from B causes it to reach all parts of the surface of the metal in the ingot-mold L in a direction transverse to the section of the ingot. As the main ladle P is at the same time moved in a longitudinal direction by its carriage D moving on tracks, as usual, it is obvious that all parts of the metal surface can be successively reached during the pouring.

C indicates the extreme position of the intermediate ladle on the one side. It `may swing to a corresponding position on the other side. When the ladle C is moved to the pc- 5 sition C, the metal can be poured directly from the main ladleP into the ingot-mold L.

In order to enable the ladle to be swung to the position C,the ties e g are of peculiar construction. The upper end of the tie g, instead of being permanently attached to the 6o carriage D, is formed with a hook h, Fig. 5, which takes partly around one of the upright bars t' of the railing. The tie e is made in two sections, of which the upper one c is linked to the lower and is formed at its end with a hook j, which hooks partly around a post/i', while the main tie-rod e is formed with a bend 7u, capable of engaging with the same post c, as shown in Figs. 5 and 6. Ordinarily the tie-rod g is connected on its end by its 7o hook 7L and the tie-rod e' is connected by its hooked. end j, as shown in Fig. 5; but when it is desired to swing the intermediate ladle to one side the hook 7L is disengaged, the hook j is also disengaged, and the tiercd eis 75 pulled u p and its bend 7o hooked over the post t', as shown in Fig. 6, thereby displacing the rods and ladle tothe positions shown in dotted lines in Fig. 4.

Instead of arranging a movable intermedi- 8o ate ladle between the main ladle and the ingot-mold I can attain the Vsame result by giving the main ladle an oscillating movement on its carriage in the transverse direction, while the carriage moves longitudinally.

I claim as my inventionl. The process of pouring molten metal to avoid formation of solid crusts imprisoned in the liquid metal, and consequent cavities in the forging, by directing the jet downwardly 9o and successively back and forth over different portions of the lmetal surface, substantially as set forth.

2. The process of pouring molten metal to avoid formation of solid crusts imprisoned in 95 the liquid metal, and consequent cavities in the forging, by directing the jet downwardly and repeatedly from side to side and from end to end of the mold to cover all portions of the surface of the ingot, substantially as Ico lset forth.

`In Witness whereof I have hereuntosigned my name in the presence of two subscribing witnesses.
