APPARATUS FOR POUR/ING METAL INTO A SERIES OF MOLDS.

Specification of Letters Patent.

Patented July 27, 1909.

Application filed March 2, 1908. Serial N0. 418,721.

To all 'whom tt may concern:

Be it known that I, l/VILHELM BRGMANN, a subject of the King of Prussia, residing at 23 Bornstrasse, Dortmund, Germany, have invented certain new and useful Improvements in Apparatus for Pouring Metal into a Series of Molds; and I do hereby declare the following to be a full, clear, and exact description of the invention.

In certain well known apparatus for casting iron, the liquid iron is poured in a continuous stream into a series of ingot molds which are caused to pass continuously under the stream of iron. With this method of casting, the necessity for leading the stream of iron from one mold to the next is attended by drawbacks which have not been removed completely by the use of devices designed to prevent the liquid iron from Howing into the space between two adjacent molds. Now according to this invention the liquid iron is poured into a series of intermittently traveling molds only while these are temporarily at rest, and when these molds have resumed their travel, the stream of iron is led into a second series of molds which are caused to travel intermittently like the rst series of molds, but in alternation therewith, so that when the iirst series of molds are in motion, the molds of the second series will be at rest, and the mold of this second series which happens to be in position under the stream of liquid iron, will be filled. Then when this mold has been filled, the stream of liquid iron will be led into the neXt mold of the first series which has been stopped and is now in position under the stream of iron ready for filling. When this mold is full, the neXt mold of th'e first series is then filled, and so on.

In the accompanying drawings :-Figure l is a vertical central cross section; Eig. 2 a plan, and Fig. 3 a longitudinal vertical section on the line A-B of Fig. 2, illustrating one form of apparatus according to this invention.

l, indicates one series of molds arranged in a circle on a turntable c. m, indicates a second series of molds also arranged in a circle on a turntable f. The two turntables c and f, are each revolved by power, or by hand, for instance by means of a ratchet lever, at determined intervals of time through a distance equal to the width of a mold. A pouring arm b, situated between the two turntables is adapted to be tipped on its longitudinal axis, and it is provided at its outlet with two spouts b1 and b2, projecting on opposite sides of the channel. When the pouring arm b is tipped for instance toward the left (F ig. 3), the liquid iron which is run into it from a ladle a that has received its charge from a blast furnace, liows through the spout o1, directed toward that side, with a constant fall into the mold Z of the turntable c, that happens to be in position underneath the stream of liquid iron issuing from the spout o1. When this mold has been filled, the pouring arm o is tipped toward the right by means of a lever c, worked by an operator from the platform 0l, (Fig. 2) so as to cause the stream of iron to flow through the outer spout b2 into the mold m of the turntable f, which has been brought in the meantime into position for being filled. At the same time the turntable c is being rotated forward through a distance equal to the width of a mold. When the mold m is full the pouring arm is tipped again to the left, while the turntable f is again rotated a step forward, and so on. The pouring arm is also provided at its outlet with a longitudinally arranged overi'iow g. If any hitch should occur in the working of the apparatus, for instance, such as a stoppage in the operation of the turntables, the pouring arm can be moved into its mid-position and then the stream of liquid iron can iiow without danger by way of the overflow g into the ladle 7i, placed underneath. When the ingots have become cool they are removed automatically or it may be, by hand, for instance, by the molds being tipped by means of a suitable implement so as to discharge the contained ingots on to a truck as indicated at z'. The molds after having been cleaned by the injection of water under pressure, and then drained dry, are tipped back at 7c, into their former upright position by' automatic means or by hand, ready to resume their journey toward the filling point.

The form of the mold carriers may vary. Instead of being constructed in the form of turntables as shown, the carriers may be constituted by belt conveyers traveling in horizontal or in inclined planes, or by a pair of vertical disks or wheels between which the molds are suspended so as to be capable of oscillatin freely, in such a manner that the molds will always take up vertical positions. Or the mold carriers may be stationary, and the ladle with the pouring arm be made to move past the said carriers. In this case the pouring arm is provided With movable spouts.

The pouring arm may have any suitable form. It may be composed of a receiving portion with a pouring portion distinct therefrom. The pouring portion may have the form of a drum, ladle or trough.

lVhat I claim as my invention and desire to secure by Letters Patent is:

1. A pouring apparatus for liquid metals and the like, comprising a pouring trough adapted at one end to receive the molten metal from a furnace and provided With lateral discharge spouts on opposite sides of said trough and a terminal overflow spout, in combination with means for oscillating said trough to pour iirst on one side and then on the other and series of molds arranged on opposite sides of said trough and adapted to be moved past the same to present an empty mold to said discharge spouts first on one side and then on the other.

2. A pouring apparatus for liquid metals and the like, comprising a pouring trough adapted at one end to receive the molten metal from a furnace and provided With lateral discharge spouts on opposite sides of said trough, in combination with means for oscillating said trough to pour first on one side and then on the other and series of molds arranged on horizontal circular carriers on opposite sides of said trough adapted to be intermittently rotated to bring an empty mold beneath said pouring spouts first on one side and then on the other, substantially as described.

In testimony whereoflhatiesigned my name to this specification,- in the-presence of two Witnesses. 4
