SWINGING LADILE.

Specification of Letters Patent.

Patented Jan. 12, 1909.

Application and May 15, 1908. Serial No. 433,042.

To all :whom it may concern: Be it known that I, VVILLIAM R. PALMER, a citizen of the United States, residing at Bridgeport, county'of Fairfield, State of Connecticut have invented a new and useful Swinging Ladle, of which the following hthese and other objects in view have dexgised the novel ladle of which the :tollowmg description in connection with the accompanying drawing is" a specification,

ieference characters being used to indicate the several parts.

Figure 1 is an elevation of my novel ladle; Fig. 2 an elevation as seen from the left 1n Fig. 1, partly broken away; and Fig. 3 is a detail horizontal section on the line 3-3 in Fig. 1, looking in the direction of the arrows.

My novel ladle comprises a shell 10 of metal, a lining 11 of brick or other suitable refractory material, circumferential bands 12 and 1.3 trunnions ll cast integral with plates 15 which are rigidly bolted in place, the bolts in practice extending through the bands and the shell. 16 denotes a notch in the upper edge of the ladle to permit slag to run off.

The essential feature of the inventionis that I provide the ladle with upper and lower tap holes. The tap holes are preferably provided with spouts which extend outward from the side of the ladle in lines at right angles to a diametrical line extending through the trunnions and are shown as placed on opposite sides of a vertical line midway between the trunnions.

1'? denotes the upper 'tap hole and 18 the lower tap hole. Surrounding thesides and bottom of each tap hole is a spout 19 which is rigidly bolted to a plate 20, the plates themselves being rigidly bolted to shell 10.

.It should be noted (see Fig. 3) that the spouts do not extend outward from the shell radially but extend from the shell in lines which intersect at right angles a diametrical line extending through the trun nions, the

purpose of this arrangement beingto insure that in pouring molten metal from the ladle to a trough the metal will flow fromthe spout into the trough longitudinally of the trough; that is to say, the stream of molten metal will not be turned obliquely against the side of the trough.

By placing the tap holes and spouts on opposite sides of a vertical line midway between the tiunnions, I insure that when slag runs off from the top of a charge of molten metal in the ladle, it will not pass into the spouts and thence to the trough but will run down the side of the ladle between the spouts and into the slag hole, which is of course conveniently located relatively to the furnace to receive slag from both furnace and ladle.

My novel ladle is adapted for use many metallurgical process in which itis required to pour a portion of the contents of a ladle and retain a portion therein for another purpose. As for example, the contents of a furnace may be tapped into the ladle, then theladle may be transferred to the place of use, the plug (not shown) in. the upper tap hole removed and metalpoured. Then the desired amount of molten metal has been poured, which may be all or any portion of the metal in the ladle above the upper tap hole, the upper tap hole is plugged, the ladle is transferred elsewhere, the plug in the lower tap hole is removed and the remaining molten metal is delivered'wherever it may be required. I

Having thus described my invention I claim: k

1. A ladle of the characterdescribed provided with upper and lower. tap holes.

2. A ladle of the character described having trunnions and upper and lower tap holes on opposite sides of a vertical line between the trunnions.

3. A ladle of the character described having a slag notch and tap holes in different horizontal planes and on opposite sides of a vertical line intersecting the slagv notch.

l. A ladle of the character described having trunnions and upper and lower tap holes provided with spouts extending outward fromthe side in lines at right angles to a diametrical line extending through the trunnions.

5. A ladle of the character described hav- In testimony whereof I aflix my signature, 1n presence of two witnesses.
