and ERNEST J. TURNER, citizens of the .United. States, residing, respectively, at Washington, District of vColumbia, and Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Feeders for Ingot Molds, of which the following is a specification.

Our invention relates to improvements in feeders for ingot molds.

The object of our invention is to provide a feeder for ingot molds which is adapted to conform with the interior wall of the mold and to be supported by the upper end of the mold and at that same time produce a feeder which will prevent piping and reduce segregation to a minimum.

Another object of our invention is to provide a. feeder for ingot molds which will closely resemble the general contour of the article to be formed from the casting and at the same time having walls arranged so that during the rolling process of the ingot any small holes or imperfections in the outer face of the ingot will be more readily rolled out of the steel and at the same time the scale formed on the outer surface of the ingot will more readily peel off during the rolling operation.

A further object of our invention is to provide a feeder of this character having means for supporting it upon the upper end of the mold and at the same time provide a simple, cheap and effective feeder wherein there is a saving in the amount of material used in its manufacture.

In the accompanying drawings:

Figure 1 is a perspective view of an ingot mold showing our improved corrugated feeder applied thereto.

Figure 2 is a vertical transverse sectional view of Figure 1.

Figure 3 is an enlarged top plan view of Figure 1 partly broken away.

Figure 4 is a top plan View of a modified form showing a greater number of inwardly curved walls.

Figure 5 is a vertical transverse sectional view of Figure 4.

. shown in Figure Figure 8 is a top plan view of'the form shown in Figure interior wall.

Figure 9. is a top plan view of the form 6 showing a cylindrical mterior wall.

In-the accompanying drawings 1 represents the ingot mold and 2 the feeder. The feeder 2 as shown is of a corrugated form havlng a large number of inwardly curved walls 3 which intersect each other. The outer face of the feeder is provided with vertically disposed ribs 4 which are semicircular in cross section and extend a considerable distance along the side of the feeder. By this arrangement it will be seen that a great number of walls are formed in the ingot and during the rolling process any holes or imperfections in the outer wall of the ingot may be rolled out and the scale more readily breaks up and frees itself from the ingot.

In Figure 4 we have shown the feeder with a' larger number of inwardly curved walls 6 and also show semi-circular vertically disposed ribs 7 carried by the outer periphery.

In Figure 6 we have shown a series of inwardly curved oppositely arranged walls 8 connected together by outwardly curved oppositely arranged walls 9. In this form like the other forms, semi-circular ribs 10 are provided on the outer periphery of the feeder.

In Figure 7 we have shown an octagon shaped feeder 11 having the eight inwardly curved walls 12. The outer periphery of the feeder is provided with vertically disposed ribs 13 which like those shown in the other forms are semi-circular in cross section.

In Figure 8 we have shown inwardly curved faces in the outer wall and a cylindrical interior wall 14.

In Figure 9 we have shown inwardly and outwardly curved outer walls and a cylindrical interior wall 15.

Having thus fully described our invention what we claim is 1. A feeder for ingot molds comp-rising a series of inwardly curved, oppositely ar- 1 showing a cylindrical ranged walls connected by outwardly curved oppositely arranged walls.

2. A feeder for ingot molds comprising a body portion having inwardly curved 5 walls connected by outwardly curved walls. 3. A feeder for ingot molds comprising a body portion having a series of inwardly curved walls connected by outwardly curved walls and integral supporting ribs 1 carried by the outer face of the body portion.

4. A feeder for ingot molds comprising a body portion having a series of curved outer Walls and a cylindrical interior wall.

5. A feeder for ingot molds comprisin a body portion having a series of curv walls connected by oppositely curved walls and having a cylindrical interior wall; In testimony whereof we affix our signatures.
