FEEDER FOR INGO'I. MOLDS.

Application filed February 9, 1924. Serial No. 691,740.

To all whom it may concern:

Be it known that BLOOMFIELD H. HOWARD and ERNEST J TURNER, citizens of the United States, residing, respectively, at Vashington, District of Columbia, and Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Feeders for Ingot Molds, 0f 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 adapted to be 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 segregation.

Another object of our invention is to provide a feeder having a number of curved walls adapted to correspond with the walls of the mold whereby any imperfection in the wall of the ingot is more readily rolled out during the rolling process and which also enables the scale on the outer surface of the ingot to more readily peel off of the ingot during the rolling process and thus produce a more perfect finished article.

A further object of our invention is to provide a feeder of this character which can be readily and cheaply made by dies and a supporting means formed as an integral part thereof and serving as means for strengthening that portion of the feeder above the mold.

In the accompanying drawings Figure 1 is a perspective view of an ingot mold showing our improved feeder applied thereto.

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

Figure 3 is a top plan view partly broken away showing one corner of the form shown in Figure 1.

Figure 4 is a top plan view of a modified form of feeder, showing the supporting ribs semi-circular in cross section and extending but a short distance down on the side of the feeder.

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

Figure 6 is a top lan view showing the belly of the side wal 5 arranged in a different arc of the circle from that shown in Figures 1 to 5 inclusive, and showing the ribs extending a considerable distance along the side of the feeder.

Figure 7 is a vertical transverse sectional view of Figure 6.

Figure 8 is a top plan View of a rectangular mold and feeder embodying our inventlon,

Figure 9 is a top plan view of the form shown in Figures 1, 4 and 6 showing straight inner walls.

Figure 10 is a top plan view of Figure 8 showing straight inner walls slightly curved at the corners.

Referring now to the drawings 1 represents the mold and 2 the feeder. The feeder 2 is formed with four outwardly bellied walls 3, 4, 5 and 6 oppositely arranged and connected at the corners. The oppositely arranged curved walls 7, 8, 9 and 10 the curves of which are arranged in a different are of a circle from that of the walls 3, 4, 5 and 6. The outer periphery of the feeder is provided on each side with two ribs 1] and 12 which are semi-circular in cross sec tion and extend a considerable distance along the side to support the feeder a considerable distance above the mold. While we have shown two of these ribs on each of the four bellied sides of the feeder, it will be understood that one rib on each side or any desired number of ribs may be employed.

In the modification shown in Figure 4 the four bellied walls 13, 14, 15 and 16 of the feeder are arranged in a different are of the circle from that shown in Figures 1, 2 and 3. In this form the supporting ribs 17 extend a very short distance below the upper end of the feeder and are semi-circular in cross section, as that shown in Figures 1, 2, and 3.

In Figure 6 we have shown the four bellied walls 18, 19, 20 and 21 arranged in a different are of a circle, from that shown in Figures 1, 2 and 4 of the drawings and like in Figures 1 and 4 these outwardly bellied sides are connected by walls arranged in a different are of the circle. In this form the ribs 22 extend-a considerable distance below the upper end of the feeder and are semi-circular in cross section.

In Figure 8 We have shown a rectangular feeder having the four outwardly bellied sides 23, 24, 25 and 26 which are connected by oppositely arranged short curved walls 27 arranged in a different are of the circle from the side walls. These walls like those shown in Figures 1, 2, l and 6 are provided with two outwardly extending ribs 28 and 29 which are semi-circular in cross section.

In Figures 9 and 10, the inner walls of the forms shown in Figures 1, 4, 6 and 8 are shown to be straight.

The reference numbers in Figure 9 indicate the same parts as similar reference numbers in Figure 1 and the reference numbers in Figure 10 indicate the same parts as similar reference numbers in Figure 8.

Having thus fully described our invention what weclaim is:

1. A feeder for ingot molds comprising four oppositely arranged, outwardly bellied walls connected by four oppositely arranged walls in a different are of a circle and two integral ribs carried by the outer face of each of the bellied walls.

2. A feeder for ingot molds comprising a body portion having outwardly bellied outer faces and straight inner faces.

3. A feeder for ingot molds comprising a body portion having outwardly bellied outer faces oppositely arranged and connected by shorter bellied faces and straight inner faces slightly rounded at the corners.

In testimony whereof we aflix our signatures.
