MACHINE FOR CASTING METAL.

sPEcIrIcATIoN'ferming part of Letters Patent No. 746,245, dated December 8,1903.

j Application filed March 16, 1903. Serial No. 147.985. (No model.)

of Fig. 1,and Fig. is a plan view of the mail chine.

The operation ofcasting-copper pigs as heretofore conducted has been very wasteful, not- Vonly because the apparatus which has beenv employed causes the spilling of a considerable portion of the metal in pouring it into the molds, but also because the pigs are cast with fins, which, absorbing oxygen from the air,become very brittle and break olf in handling and shipping, thus occasioning a very considerable loss. v

The object of my-invention is top provide means whereby the present losses resulting from the shipment of copper, whether the same be in pigs, slabs, or bars, may be elimi nated. To accomplish this result, I usel a water-jacketed mold which is closed at thelower end and is shaped to give the pig the desired conformation. The ingot castv therein has all its iins concentrated at the upper open end of the mold, and the tins when so concentrat-ed may be readily removed by suitable cuttingor trimming machines, so that in pouring and shipping nop-art of the copper will be broken loose and lost.

In the accompanying drawings, 2 represents the frame of the machine, and 3 is the mold, which is of greater height than width and is formed with hollow walls 4 for the passage of a stream of Water and with trunnions v5 5 at about the middle of its height through which inlet and outlet pipes 7 and Sextend for the introduction of water to cool the mold. The water enters a chamber 4 at one side of the mold, from the top of which it' overflows through a passage 4a into the'main water-passage around the mold-cavity. Thence afftpr lling the main cavity it iiows through a passage 4b at the top into a side chamber 4c,

the machine-frame and adapted to constitu te from which it iiows through the outlet-pipe 8. Y'

As the mold is lling the air rises to the top of the chambers and is displaced through the passages 4a and 4b and is caused to go out through the pipe 8. To rotate the mold on its trunnions, I prefer to employ a pinion 9, fixed to one of the trunnions and operated bya rack 10, xed to and movable with a cylindex' 11, which is reciprocated on a plunger 12, the latter being hollow and serving for the introduction and dischargeof the water or compressed air by which the cylinder is operated. The lower end of the mold is shaped'with an inwardly-projecting portion, as shown in Fig. 4, so as to form an ingot with a concave end, which is of very convenient form for handling, and I preferably set in 4the mold a detachable piece 13, which forms in the oase of the concavity a rosette or tablet portion 14, Fig. 2, on which thev name of the person for whom the `ingot is made may be cast or the weight of the ingot may be stam ped.

As the upper end 0f the mold is open, the top 'of the ingot isirregular in form, and all the fins being concentrated'at that end may readily be trimmed off by machinery after the Y ingot has been discharged from the mold.

15 15 are wheelsjournaled in uprights of rests for the t-runnion of the ladle, and 15' is the mold.

The parts being in the position shown in Fig. 1, molten metalv is charged into the ladle 16 from a furnace or converter in proximity to which the casting-machine is set,'and the ladle is tilted on the wheels 15, so as to teem the molten copper into the mold. The mold has a capacity a little in excess of the capacity of the ladle, so that the ladle may be emptied into the mold. There is-therefore no surplus of metal and no loss in pouring. pig has been cast, the ladle is righted andthe mold is rotated on its axis into an inverted y position, whereupon the pig drops` from the open end of the mold, the mold-cavity being of flaring shape, so as to cause its discharge'. The mold can then beuighted land another pig cast therein. The operation is thus very rapid and can be carried on with the labor. of only one man. l

Fins which are trimmed from the pigs can `a spout to conduct the metal to the cavity of y When the' Y y roo.,

be returned to the refining-furnace for retreatment or, if desired, to the mold and become incorporated in the next pig that is cast.

Within the scope of my invention the apparatus may be modified in Various Ways, since What I claim, and desire t0 secure by Letters Patent, is-

l. A machine for casting copper pige, having a wetter-cooled mold open at the top and provided with a closed inwardly-projecting bottom portion adapted to form a hand-hole on the bottom of the pig; substantially as described.

2. A machine for casting Copper pigs, having a water-cooled mold open at the top and provided With a. closed inwardly-projecting bottom portion adapted to form a hand-hole 0n the bottom of the pig, and with a, detachable piece on said inwardly-projecting p0rtion adapted to cast e, distinguishing-mark at the end of the concavity; substantially as described.

In testimony whereof I have hereunto set my hand.
