FOUNDRY-LADLE.
SPECIFICATION forming part of Letters Patent No. 619,431, dated February 14, 1899.
Application filed March 16, 1898. $erial No. 674,026. (No model.)
To all whom it nuty concern:
Be it known that LDANIEL WILLIAM NASH, a citizen of the United States, residing at Eastlake, in the county of Jefferson and State of Alabama, have invented certain new and useful Improvements in Foundry-Ladles; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to improvements in foundry-ladles in which an interior cylinder is placed forming a receptacle to receive the molten metal from the cupola; and the objects of my improvement are, first, to provide a foundry-ladle with an internal cylinder to form an inner receptacle to receive the metal from the cupola; second, to provide proper facilities to elevate or raise the interior cylinder from the ladle bottom to allow the metal to escape therefrom to the ladle; third, to provide a foundry-ladle with an interior receptacle adapted to be raised from the ladle bottom to allow the metal to flow therein, the slag and cinder being retained in the receptacle. Iattain these objects by the mechanism illustrated in the accompanying drawings, in which Figure l is a top view of a foundry-ladle having my improved slag-separator attached thereto. Fig. 2 is a vertical sectional view of the same through the center. Fig. 3 is an enlarged detail vertical view of the elevating and clamping device with the connecting-arm attached to the interior cylinder. Fig. 4 is a vertical cross-section of the same through the center.
Similar numerals refer to similar parts throughout the several views.
The foundry-ladle 1 as shown represents the form of ladle in general use. The outer shell is made of suitable metallic material, the shell being lined on the inside with fire-clay 2 in the usual manner. My device can be used on any other form of ladle desired.
The internal cylinder 3 can be made of any desired metallic material, a series of spurs 1 being formed on the outside near the lower end, the spurs extending outward to nearly fit the ladle. The metallic cylinder is covered with fire-clay 5 in the usual manner to protect the same from the molten metal. The connecting-arm 6 is attached to the head of the internal cylinder in any desired manner. The arm extends at a right angle from the cylinder to the edge of the ladle, at which it is bent to extend downward on a vertical seat formed on the side of the ladle. The downwardly-extending shank of the arm is provided with a circular aperture 7, and an oblong aperture 8 is formed therein.
The stud 9 is rigidly attached to the ladle side. The stud extends through the circular aperture formed in the arm-shank. An eccentric cam 10 is mounted on the stud, the cam engaging the aperture formed in the shank. A flange 11 is formed on the outer edge of the cam, and a handle 12 is attached thereto to operate the cam. The nut 13, having a handle 14, is attached by screw-threads to the outer end of the stud 9. The nut when screwed up presses the cam-flange on the armshank and holds the same rigidly to place at any desired position. The stud 15 is rigidly attached to the ladle side. The stud extends through the slot-aperture formed in the armshank. A key 16 is inserted in the end of the stud to hold the shank to place.
In operation, the molten metal is run from the cupola to enter the receptacle formed in the center of the ladle. The slag and cinder, being lighter than iron, will float on the surface of the metal. The center receptacle when raised by the action of the cam will allow the metal to flow under the lower edge thereof and enter the ladle, the slag remaining in the receptacle. The cleaned metal in the ladle can then be poured in the molds and the operation repeated as often as desired.
The ladle when turned for pouring, brings of and having an apertured stem extending downwardly on the outside of the ladle, the eccentric cam operating in the aperture formed in the arm-stem, and the nut to clamp the [5 cam, substantially as described.
In testimony whereof I affix my signature in presence of two witnesses.
