GASTING APPARATUS.

Specification of Letters Patent.

, Patented Sept. so, 1913.

Application filed November 1, 1912. Serial No. 729,684.

the said portions meeting in flows in opposite directions and merging one into the other, both metals being simultaneously teemed into the mold.

In simultaneously teeming the metals into the mold from ladles 'at considerable distances above the mold, through orifices in the bottoms of the ladles and'with considerable depth of metals in the ladles, the m0- mentum acquired by the metals falling under these conditions produces, when the metals meet in. the inoldfiowing in opposite directions, such agitation as to broaden andrender irregular the zone of merger which it is desired shall be vertical and of small lateral area, in order that large portions of the ingot shall be the same in quality as the metal in the ladle from which the respective portions are poured.

Theinvention described herein has for its object the separation of the metal to be relatively small streams,.and the retardation in the rate of flow without diminishing the quantity of metal delivered into the mold in a given time. It is a further object of the invention to provide for the heating of the distributer and thereby preventing the accumulation of solidified metal on the walls and in the outfully lets of the distributer. o The invention is hereinafter more described and claimed. v

In the accompanying drawing forming a part of this specification, Figure 1 is a top plan view of my improved distributer; Figs. 2 and 3 are sectional views, the planes of section being indicated respectively by the lines II-IIand III-III, Fig. 1.

In the practice of my invention the distributer consists of an outer shell I preferably formed of metal and a. lining 2 of refractory material. As the bottom of the charged into the mold into a plurality of.

shell is inclined upwardly from a median line, shoulders 3 are preferably formed thereon to insure a good bearing on the end of the mold. The receptacle is divided into two compartments by a transverse partition 4 and through the bottom of each compartment are formed cutlets 5 and 6, which are preferably so arranged that the several streams of metal will enter the mold at points adjacent to the corners, and therefore I as widely separated as possible. ,As will be seen by reference to the drawings, the bottoms of the compartments are so constructed that the surfaces incline toward the outlets, thus insuring a complete discharge of the metal.

In order to prevent the walls and outlets of the distributer becoming clogged by solidified metal, a roof 7 is arranged to cover the distributer except at the ends' at which the metals are teemed into the distributer. \Vhile this roof, which hasits undersurface protected by refractory material will reflect the heat onto the metal flowing throughthe compartments thus preventing a large loss by radiation, it is preferred that its under surface should be raised to a temperature approximately that of the molten metal. To this end a suitable electrical resistor 8, such as'carbon or a suitable metal is incorporated in the roof and adapted to be connected to a suitable generator.

\Vhile my improvement is adapted to simultaneously direct the metal from two ladles, which may contain the same kind or grade of metal, thus reducing the time heretofore required in filling the'mold, it is especially adapted for.making compound ingots containing two different kinds or grades of metal which are teemed into the distributor from separateladles. The proportions of the different kinds of metal to i that such rate will diminish as the metal rises in the mold. It is also characteristic of my improvement, that the respective of one kind of metal and 30% quantities flowing into the mold are not dependent on the relative quantities teeined into the distributer provided of course suffi cient metal is poured into the compartments to fully compensate for the outflow through the outlets 5 and '6. Hence by properly proportioning the outlets 5 and (5 relative to one another, it can be made certain thateach one of a series of ingots will have the same relative amounts of metal as all the other ingots of the series.

I claim herein as my invention:

1. A metal distributer movable from mold to mold, having in combination independent,

chambers or compartments for the reception of metal, each compartment having a plurality of separated outlets.

2. A metal distributer movable from mold to mold, having in combination independent chambers or compartments for the reception of metal, each compartment having a plurality of separated outlets, the outlets from one compartment having a combined delivering capacity greater than the combined capacity of the outlets from the other compartment.

3. A metal distributer, having in combina tion independent chambers or compartments, each compartment having an outlet, and a roof arranged above the compartments and adapted to reflect back the heat radiating from the metal flo'r-z'ing through said compartments. r

4. A metal distributor, having in combination independent compartments or chambers, each compartment provided with an outlet, a roof arranged above the compartments and adapted to reflect back the heat radiating from the metal flowing through said compartments, and means for applying heat to the surface of such metal.

In testimony whereof I have hereunto set my hand.
