CASTING-LADLE FOR STEEL AND IRON.

SPECIFICATION forming part of Letters Patent No. 612,134, dated. October 11, 1898. Application filed August 18, 1897. Serial No. 648,645. I (No model.) Patented in Belgium April 22, 1896, No. 121,014.

To all whmn it may concern.-

Be it known that I, TOUSSAINT LEVOZ, a subject of the King of Belgium, residing at 14 Rue du Trone, Brussels, Belgium, have invented new and useful Improvements in Casting-Ladles for Steel and Iron, (for which I have received Letters Patent in Belgium, No. 121,014, dated April 22, 1896 and I do hereby declare the nature of this invention and in what manner the same is to be performed to be particularly described and ascertained in and by the following statement.

The casting-ladles ordinarily used present various grave defects. Being wide at the top, they present a large surface of molten metal to the air, and this causes injurious cooling and oxidation. It is impossible to pour the metal therefrom without carrying slag with it. The skimmer gets burned about the legs when the 'metal is cast, and, moreover, the operator who directs the casting is blinded and burned about the face by radiation from the molten metal and cannot properly direct the operation. It has been sought to remedy these defects by adopting a ladle divided into two compartments by a vertical sheet-metal partition covered with refractory clay. This partition, which separates the inlet for the metal from the outlet, does not extend entirely to the bottom of the ladle, so that the two compartments communicate at the bottom. The metal flows into the first compartment, passes into the second by the passage at the bottom, and as the scorize float'on the top in the first clean metal can be poured from the outlet. Skimming is also easy and sure. Unfortunately, however, the partition and the flaring sides cause coolingand the metal frequently sets in the second compartment and this makes casting impossible.

The object of the present invention isto remedy all these disadvantages,maintaining the fluidity of the metal, permitting the same to be easily skimmed, and, the ladle being closed at the top, there will be much less contact with the air and the operator will neither be blinded by the glare nor burned in the face.

In the accompanying drawings, the invention is illustrated by Figures 1, 2, and 3, re-

spectively, elevation, vertical section on line X X, Fig. 1, and horizontal section on line Y Y, Fig. 2.

The ladle consists of two truncated cones united at their bases and connected by bolts and keys at b. This arrangement serves to facilitate the removal of scraps of cold metal. Above the ladle has a lid A and a spout B, within which is placed a movable brick 0, made of refractory clay, very hard and of special shape. This brick skimsthe metal and allows the metal to flow free from scorize.

The metal is poured into the ladle to a convenient height and is distributed to the molds by the spout B. The bulge in the shape at the level of the clamping-rim permits the metal to flow readily through the passage 19 19 between the brick (J and the face of the spout B. The brick is at least four to five centimeters thick, its thickness varying with the size or capacity of the ladle. The operator in casting has only to see that the passage 19 p is always full. The scoriae will then always fioat at the top behind the skimmingbrick, allowing very clean and very fluid metal to be cast. On the other hand, the lid prevents contact of the metal with air and also glare or heat reaching the operators face. Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is- A casting-ladle consisting of two truncated cones placed with the bases or larger ends in contact and removably secured together, the upper cone having an opening in its side above the bulge or enlarged central part of the ladle, a spout leading therefrom, a movable cover for the ladle and askimming-brick extending down into the spout across the opening in the wall of the ladle, substantially as described.

In witness whereof I have hereunto set my hand in presence of two witnesses.

TOUSSAINT LEVOZ.
