FEEDER FOR INGO'I. HOLDS.

Application and February 15, 1924. Serial m. eeaoea.

To all 'whom it may concern:

Be it known that BLOOMFIELD H. Howann ;and Ems'r J. TURNER, citizens of the United States, residing, res Washington, District of Co umbia, 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 lmprovements 1n feeders for ingot molds.

The object of our invention is to rovide a feeder for ingot molds adapted to supported on the upper end of the mold and also provide a feeder which will prevent the formation of what is known as piping and at the same time reduce se gation.

Another object of our invention is to provide a feeder havin a number of walls adapted to correspon with the walls of the mold and which has a marked advantage in that it more nearly conforms to the shape of the article to be rolled from the ingot and to enable the imperfections in. the outer surface of the ingot to be more readily rolled out and also cause the scale on the surface of the ingot to more readily peel oil during the rolling process.

A further object of our invention, is to provide a feeder of; this character having certain arrangement of walls to accomplish the above result and at the same timeprovide a simple cheap and effective feeder.

In the accompanying drawings:

Figure 1 is a perspective view of an ingot mold showing a feeder thereon embodying our invention.

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

Figure 3 is a top plan view showing a modified form of feeder in which the walls are bellied inwardly.

Figure 4 is a top plan view of the form shown in Figure 3 with straight wall faces.

Figure 5 is a top plan view of Figure 3 showing a straight circular interior wall.

Figure 6 is a top plan view of Figure 1 showing a straight circular interior wall.

Figure 7 is a top plan view of Figure 1 tively, at

' showing the inner walls bellied inwardly and the outer walls straight.

Referring now to the drawings 1. represents the mold, and 2 the feeder. The feeder as shown is octagonal in cross section having the eight walls and the outer face of a number of walls provided with vertically disposed ribs 3 semi-circular in cross section. While we have shown these ribs 3 arranged on four of the walls it will be understood that each wall could be provided with a rib or any desired number of ribs can be em ployed.

In Figure 3 of the drawings, we have shown an octagon shaped feeder in which the eight walls are bellied inwardly as indicated at 4 and are connected by outwardly bellied walls 5, the arc of a circle of the walls 5 being considerably less than that of the walls 4. Inthis form likev that shown in Fi ures 1 and 2 any number of the walls may e provided on their outer faces with vertically disposed ribs 6 semi-circular in cross section.

In Figure 4 we have shown theeight walls Figure 6 is a top plan view similar to'ga Figure 1 showing the inner wall also of circular contour as indicated at 9.

Figure 7 shows the form'shown in Figure 1 ilvith inwardly bellied walls as indicated at 0.

Having thus fully described our invention what we claim is a 1. A feeder for ingot molds comprising eight walls bellied inwardly and connected by outwardly bellied walls.

2. A feeder for ingot molds comprising a body portion composed of eight inwardly bellied walls connected by outwardly bellied walls the arc of which is less than the inwardly bellied walls.

3. A feeder for ingot molds comprising a body portion formed of eight curved walls connected by curved walls, the arc of which is less than that of'the first mentioned walls. 4. A feeder for ingot molds comprising a '5 5. A feeder for ingot molds comprising a tures.

body portion formed of eight curved walls connected by eight short curved walls, the

arc of which is less than that of the first mentioned walls.

tending the opposite direction and arranged in a dlfi'erent arc of the circle from that of the first mentioned walls. 10

In testimony whereof we affix our signabody portion having eight curved walls BLOOMFIELD H. HOWARD. connected by eight short curved walls ex ERNEST J. TURNER.
