LADLE FOR HANDLING MOLTE'N STEEL, 80C.

SPECIFICATION forming part of Letters Patent No. 506,328, dated October 10, 1893.

I Application filed Uctober 22, 1892- Serial No.449,549. (No model.) 7

To all whom it may concern.-

Be it known that I, FRANK MORRIS, of- Alliance,in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Ladles for Handling Molten Steel, &c.; and I do hereby declare the follow-.

" a side elevation partly in section of a ladle embodying my invention. Fig. 2 is a similar view in end elevation. Fig. 3 is a view in perspective of the slide valve or stopper, and Fig. 4 is a view in side elevation of the slide-valve or stopper.

A represents a ladle provided with saucer shaped bottom a, the lat er having a centrally located opening therein for the escape of the molten metal. The sides and bottom of this ladle are designed to be covered, with fire clay or brick or other material asis-ordinarily-done, and the central opening-therein is provided with a brick made-of fire clay or any other suitable material having a central opening for the passage of the metal. This brick C is preferably cylindrical in form, concaved on its upper face and projects below the bottom of the ladle so that theunder side thereof rests in close contact with the sliding-valve or stopper E. This slidingvalve or stopper E consists of ametal frame E having a recessed face and an opening e, and also provided with side flanges j, which lattcrrest upon the slide-ways g secured to-the under side of the ladle. These slide-ways are preferably in a plane above the lower face of brick (i so that in the event of any metal escaping between the brick O and the slidingvalve it cannot come in contact with the slide-ways. Seated within the recess in the metal frame E is the brick E made of fire clay or any other suitable material. This brick is provided with an opening registering with the opening in the metal frame and also adapted toregister wi th the opening in the brick O. The brick E rests snugly against the lower face of the brick C, and when moved to bring the openingsinline the metal within the ladle is free to flow through the same. By moving the sliding-valve or stopper lorgitu'ilinally the opening in the brick E is carried to one side of the opening in brick 0, thus cutting off the flow of metal. The brick E projects through the opening in the frame so that the metal in passing from the ladle comes in contact first with the brick G and then with brick E and is dis-- charged from the latter in a plane below the bottom of the frame E and also below the slide-way carrying the sliding valve or stopper. The sliding-valve is actuated by thelever II, which is preferably of the bell-crank variety and is pivoted to the bracket it projccting from the side of the ladle, the short arm of said bell-crank being connected to the slidingvalve or stopper E by the pitman h. The valve is limited to its movement in one direction by the closed end of the slide way and in the opposite direction by the stop I secured to the ladle and engaging the short arm of the bell-crank lever. By moving the valve until the latter engages the closed end of the slide-way the discharge openings in the brick C and E are brought into line and by moving the valve in the opposite direction until the short arm of the bell-crank engages stop I, the opening in the brickE is carried beyond the opening in brick C and the flow of metal cut off.

Having fully described my invention, what Iclaim as new, and desire to secure by Letters Patent, is-- 1. The combination with aladl'e having an opening in its bottom, and slide ways secured to the bottom of the ladle, of a slide valve or stopper comprisingaframe having open sides and flanged ends, and a bl ick carried bysaid frame, the brick having an opening therein and its upper face adapted to be in a horizontal'plane below the plane of the flanges, substantially as set forth.

2. The combination with a ladle having an opening in its bottom, and provided with a lining which extends through the opening and 1 ed to receive a depending portion of thebrick, below the bottom,and slide ways secured to the and means for sliding the valve, substantially bottom in a, plane above the plane of the as set forth. lower face of the portion of the lining which In testimony whereof I have signed this 5 extends below the lad1e,of a slide valve comspecification in the presence of two subscribx5 prising a frame composed of a plate having ing witnesses. flanged ends the flanges of which are constructed to travel on the slide ways, said Witnesses: frame adapted to carry a brick and to that H..-W.
