CASTING PLANT.

SPECIFICATION forming part of Letters Patent No. 618,447, dated January 31, 1899.

Application filed March 5, 1897. Serial No. 626,108. (No model.) V

To all whom it nuty concern:

Be it known that I, MAXIMILIAN M. SUPPEs, of Lorain, Lorain county, Ohio, have invented certain new and useful Improvements in Metal-Casting, of which the following is a specification.

The object of my invention is to provide apparatus for the casting of metal which shall lessen the waste, reduce the cost both of the apparatus and of running expenses, reduce the amount of space required, and enable the casting to proceed with as few as possible of those delays which arise from breakdowns.

My invention is particularly adapted for the casting of blast-furnace products and is intended to supersede the large casting-yard which has been usually provided hitherto; and my invention consists in the provision of a novel form of casting-bed composed of moldcarrying cars abutting to form a continuous casting-bed and in the provision of various other apparatus to cooperate with the casting-bed, as will be more fully set forth here-' inafter.

Referring to the drawings, Figure 1 is a view, partly in section, of the ladle, metal reservoir and runner, and mold-carrying car. Fig. 2 shows a longitudinal vertical section of the mold-carrying car with the runner in position thereover. Fig. 3 is a plan view of the mold-carrying car. Fig. 4 is a plan view of the metal reservoir and runner. Figs. 5 and 6 are respectively side and end views of a crane-harness. Fig. 7 is a diagrammatical view illustrative of the general utility of my invention.

A represents one of the ladles adapted to receive the molten metal from the furnace and is mounted upon a suitable truck. The metal is poured from A into my improved metal reservoir and runner B.

13 comprises a metal-reservoir B swiveled at 1) upon the stand B, which is placed between the'track 1 and the casting-track 2. The metal-reservoir B is located so as to receive the metal from the ladle A, while the runner B is adapted to extend over the top of the casting-car O or be thrown away from over the track to allow the passage of a'locomotive or to permit uninterrupted repairs. The runner B has spouts 1), b b b and b adapted to rapidly deliver the metal from the runner to the molds, as hereinafter pointed out.

O is a mold-carrying car carrying the bed 0', which I prefer to divide into a plurality of sections 0 each having several open molds m m. These sections are secured together,- as by bolts h h, so that any section may be readily renewed.

O (l are hooks by which the car may be lifted. They are secured to members which are adapted to slide longitudinally be neath the bed 0, so as not to prevent the beds of different cars from being pushed together.

O is an undercut hook having the counterweighted end 0 pivoted about a pin 0 and having a stop 0 to limit its movement. It is adapted to couple with pin 0 at the end of the next car. By this arrangement when the cars are pushed the ends of the mold-beds abut, but when they are pulled they auto matically couple, and space is left between the beds to adapt the cars to travel on curves.

During the casting operation it is intended that the cars be pushed,'preferably by a locomotive geared for low speed or a powercable. By doing this the metal from the ladle A is poured continuously into the metalreservoir B thence passing continuously through the runner B and spouts 1), b b b and 19 into the molds m m of a continuous and uniformly-moving casting-bed.

By the arrangement of spouts shown. I am enabled to pour very quickly, for while the spout b is filling one of the molds at the farther side of the car I) and b are each filling a mold in the center section of the car and b and b are filling corresponding molds at the side of the car nearest to the metal-reservoir B By adjusting the inclination of the lips and the runner at their proper relative angles the molds will fill at a substantially uniform rate.

It will be seen that I am enabled to cast the product of a number of furnaces in a small space, as the cars may be drawn away from the cast-house as soon as they are filled.

I do not provide cumbersome or expensive apparatus, such as machines having rotary casting-beds, and it is therefore practicable to supply spares for all parts of the system, thus reducing delays to the minimum.

At the end of the casting process the cars may be taken at once to whatever part of the plant they are to be unloaded.

In Figs. 5 and 6 I show the harness F,which I prefer to use for unloading the cars. This comprises an eye F, adapted to engage a hook on the crane-chain, a cross-beam F pivoted to the eye, depending rods F F pivoted to the cross-beam, carrying between them pins F F adapted to engage the books 0 C and lift the entire car. Secured to the rods F F is the angle -iron F through which passes the key Ffl-engaging a recess in the casting-car. This key may be removed from the recess by a pull of the cranemans chain F acting on the lever F WVhen the key is thus removed, the car, being top-heavy when loaded, dumps its load and then swings back to its normal position. The key prevents the unloading of the car until desired.

The diagram shown in Fig. 7 illustrates the advantages of my invention. A ladle is shown on track 1. The casting-cars are on track 2, being pushed by the geared locomotive G. On the loop 3 of the crane-track 3 a portable crane is shown in the act of lifting a mold-carrying car from track 2 to dump its metal into the stock-yard. A crane on track 3 is dumping the metal from a castingcar to a fiat-car E on track 4:.

It is evident that traveling cranes may be used instead of portable ones.

I desire to be understood as not limiting myself to the specific details of construction and arrangement which I have shown and described, for it is clear that my invention is broader than the specific embodiment which I have disclosed, so that modifications which are Within the scope of the appended claims will readily suggest themselves to those skilled in the art.

My invention may be advantageously used for casting other products than those of the blast-furnace, and I do not, therefore, restrict myself to such use.

What I claim, and desire to protect by Letters Patent, is

bed movable along said parallel track, and a plurality of rotatable metal-reservoirs located between the said tracks and each having a horizontal runner secured thereto and adapted to extend over said casting-bed.

3. In a casting plant, the combination of a horizontal track, a ladle movable along said track, a second track parallel with said firstmentioned track, a plurality of mold-carryin g cars abutting each other to form a continuous casting-bed, and movable along said second track, a metal-reservoir between said tracks and a horizontal runner secured thereto and extending above the said casting-bed.

4. In a casting plant, the combination of a horizontal track, a ladle movable along said track, a second track parallel with said firstmentioned track, a plurality of mold-carrying cars abutting each other to form a continuous casting-bed and movable along said second track, a rotatable metal-reservoir between said tracks and a horizontal runner secured thereto and extending above the said castingbed.

5. In a casting plant, the combination of a horizontal track, a ladle movable along said track, a second track parallel with said firstmentioned track, a plurality of. mold-carrying cars abutting each other to form a continuous casting-bed and movable along said second track, a plurality of fixed stands between said tracks, a metal-reservoir vertically swiveled to each stand and a horizontal runnersecured to each reservoir and adapted to extend above said casting-bed.

6. The combination of a horizontal track and a ladle movable along said track, a second track and a plurality of detached cars which abut to form the casting-bed having three parallel series of disconnected molds movable along said second track,a fixed stand carrying a rotatable reservoir, adjacent to said castingbed, and ahorizontal runner connected with said reservoir and having independent spouts for each of the three series of molds.

'7. A mold-carrying car having lifting-pins extending beyond the end of the mold but adapted to be moved entirely beneath said mold and having a coupling device which antomatically connects adjacent cars when the cars are separated but passes freely under adjacent cars when the cars are pushed toward each other.

In testimony whereof I have affixed my signature in presence of two witnesses.
