which the side walls 15 are provided with upper, forward extensions 16 equipped with bearings 17 disposed on a line in advance of thd plane of the front wall of the carriage, there being piv otecl to the supports 2 by means of pivoting members or bolts 18 connecting members or links 19 in turn pivoted at their lower ends to the carrier 14 by means of pivoting members or bolts 20 entered through the bearings 17.

The carrier 14 is adapted to receive a vessel or ladle 21 having a pair of discharge lips or spputs 22 and equipped with oppositely disposed ears28, fixed to p the sides of the ladle and each provided with a pair of outwardly projecting trunnions 24, 25, of which the latter enter seats or recesses 26 formed in the upper edges of the side walls 15 when the ladle is positioned in the carrier, there being also provided on the ladle 21 at points vertically beneath the trunnions 25, out wardly projecting retaining members or trunnions 27 adapted to enter upwardly opening boxes 28 fixed to the inner face of the walls 15 and to be secured in said boxes by means of removable keys 29 adapted to be entered through the boxes above the trunnions.

Sustained adjacent the carriage are movable molds 30 adapted to pass successively beneath the forward lip 22 of the ladle and to receive the molten metal from the latter. The molds are shown herein as being carried by a rotary mold frame 31, it being understood that after one of the molds has been properly filled,

the frame is rotated in a suitable manner for bringing another mold in position relative to the ladle.

In practice, the charge from the furnace or converter isin its molten state poured into the ladle 21 which isthereafter moved to and positioned in-the carrier 14, it being understood that the ladle may be moved in any suitable manner, as, for example, by means of a crane from which the ladle will be suspended by means of the trunnions 24. After seating the ladle in the carrier the keys 29 are inserted through the boxes 28 over the trunnions 2'7 and one of the molds is positioned vertically beneath the adjacent discharge spout; 22. The parts having been thus arranged, the carriage 14 is raised through the medium of the lifting device, in the operation of which the lifting member 8 is raised by liquid under pressure admitted to the cylinder 6 whereby the carriage l4 and the ladle contained therein are carried upward. During each such movement of the lifting member the carriage 14 and ladle 21 are tilted forward through the medium of the links 19, and this action is continued until all the metal has been discharged from the ladle,

which then occupies the position shown in. "ig'. l. It will be observed that as the member 8 moves lip-- wardly, the carriage swings on the luleruin l3 while the lower ends of the links 19 swing torn orally on the axes 18 from the position seen in Fig. 3 to that shown in Fig. 4, thus causing the mouth of the ladle to travel over the underlying molds at a practically uniform height above the same and in a directir from front to rear thereof, whereby the metal in during the mold; filling operation, be deposited at constantly changing points in the mold, thus obviating the molten metal being deposited at a Si l spot on the mold and consequently prolonging the life of the mold. Further, it will be obscrv that alter the mold has been filled, the power applied to the memher 8 may be instantaneously relieved to thus lower the ladle to non-discharging position, the device being thus under complete control oi the operator to pen init the mold being properly iilled w i. thou t overflowing.

It may be mentioned in conclusion that llC-EQljOiOl'C it has been the general practice to pour the molten metal directly from the converter into molds menu to d upon a hand-operated carriage, this mode of handling the material being expensive not only in the matter of labor and equipment, but also as a result of the loss attendant upon the inactivity oi the converter during the metal pouring operation, and this especially in instances where the converter space or capacity is limited. Also the practice has been. in vogue oi util izing a traveling crane for operating a ladle to receive the contents of the converter and discharge it into the molds, which operationis objectionable to the extent that the crane is thereby monopolizcd and that the amount of metal discharged from the ladle cannot be properly controlled, especially in filling small or shallow molds. With the improved apparatus as above described, these bbjections and diiiicuities are all overcome and provision is made for properly handling the molten metal, discharging the ame into molds and'permitting of this without interrupting the operation of the converter or monopolizing the use of the crane.

It is to be understood that while we have herein shown and described a hydraulic lill in; devic for raising the ladle carriage during the lilting or pouring operation, other forms ol lilting devices, such-as a rack and pinion or in some instances a drum and cable may be employed for the purpose and thi without departing from the spirit oi the invcnli i, the essence oi which resides in positively guiding the pivotal axis oi the carriage and likewise oi the ladle in a determined port th W ule the met 1 is being discharged. Further essential to the principle oi the invennow-merit oi the pivotal axis of the carriage and ladle shall be in a vertical plane, as herein described, as such movement may, under certain conditions, be ehected in an inclined or even in a curvilinear path, the chief aim of the invention being to effect a movement ol the ladle in a plane over the bottom of, and

the molds are drscribed being carried by a rotary home, it a l be understood that they may be moved Linear or other path, the only essential, in

in a re "this connection, being that they be brought successively beneath the ladle spout.

In an apparatus of the class described, a lifting de vice lncludi' j' a carrier. 3. ladle pivotally supported thereon and bovine a pouring lip. and means actuated by the lifting inc inisin for tilting the ladle during; the operation of r e the carrier and for imparting to the pouring id lntile it lateral movement.
