FEEDER FOR INGOT MOLDS.

Application filed December 29, 1923. Serial No. 683,500.

To all whom it may concern:

Be it known that BLOOMFIELD H. How- ARD 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 cer tain new and useful Improvements in Feed-- ers for In ot Molds, of which the following is a specifl cation.

Our invention relates to improvements in feeders for ingot molds.

The object of our invention is to provide a feeder for ingot molds for casting iron or steel ingots and which prevents holes known as piping and which will also reduce segre ation.

Anot er object of our invention is to provide a feeder having a bore therethrough having a beveled upper end to facilitate the pouring of the molten metal especially inthe manufacture of small ingots.

. Another object of our invention is to provide a feeder of this character provided with .supporting means at its upper end to support it on the upper end of the mold with a portion thereof extending into the mold and at the same time providing means for strengthening the feeder and yet at the same time greatly reducing the amount of material in the manufacturing thereof.

A further object of our invention is to provide a feeder with suflicient strength to withstand the pressure of the molten metal coming in contact with its inner walls and to resist the expansion due to the contact of the feeder walls with the hot steel or iron and at the same time require the smallest possible quantity of material in its manufacture.

A still further object of our invention is to rovide a simple, cheap and efiective feed r having certain details -of structure and combination of parts hereinafter more fully set forth.

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

Fi re 2 is a vertical sectional view showing 1; e feeder partly in section.

Figure 3 is a transverse sectional view taken on the line 33 of Figure 2 and lookin in the direction of the arrows.

Figure 4 is a perspective view of an ingot mold showing a modified form of feeder therein. 1

Figure 5 is a perspective view of a mold showing a fluted feeder embodying the form shownin Figures 1, 2 and 3.

Figure 6 is a side elevation of a modified form of feeder.

Referring now to the drawings 1 represents the ingot mold and 2 the feeder which extends into the mold. The upper end of the feeder is provided with an annular flange 3 extendin all the way around which may be of any esired width or thickness and which strengthens the feeder. Extending downwardly from the lower face of the flange 3 are the ribs 4 which are formed integral with the said walls of the feeder and their lower ends rest upon the upper end 5 of the mold 1 whereby the feeder is supported upon the upper edge of the mold.

While we have shown and described but a single rib on each of the four walls of the feeder it will be understood that two or more ribs may be, formed on each wall. These ribs as will be readily understood strengthen the side walls of the feeder and also serve as a support for the feeder to rigidly hold it upon the upper edge of the mold. The flange 3 is beveled as indicated at 6, to facilitate the pouring of the metal into the feeder.

In the modification shown in Figure 4 the feeder 2 is provided with two annular flanges 7 and 8 spaced apart and connected by ribs 9. While we have shown but a single rib, connecting the flanges 7 and 9 on each side it will be understood that any number of these ribs may be used the same as referred to in the preferred form shown in Figures 1, 2 and 3. Extending from the lower flange 8 on each side is a rib 10 which engages the upper edge 5 of the mold 1 and whereby the feeder is supported in the up per end of the mold. We have shown but a single rib on each side of the mold extending from the flange 8 but any number could be used which strengthens the feeder and In the modification shown Figure 6 of the drawings each side of the feeder 14.

is provided with a downwardly extending therethrough beveled at its upper end.

2. A feeder for ingot molds comprising a body portion having a shoulder at its upper end and a bore therethrough beveled at its upper end.

3. A feeder for ingot molds comprising a body portion having a flange extending around its upper end and ribs formed integral with the flange and the body portion of the feeder.

4. A feeder for ingot molds comprising a body portion having a flange extending around its upper end and ribs formed integral with the flange and extending downwardly along the side walls of the feeder.

5. A feeder for ingot molds comprising a body portion having an annular flange and ribs extending from said flange and formed integral therewith and with the bodyportion.

6. A feeder for ingot molds comprising a body portion an annular flange extending around the upper end and liavi abeveled edge and ribs extending from the lower face of the flange and formed integral with the body ortion of the feeder.

7. 1E feeder for ingot molds comprising a body portion having two or more annular flanges extending therearound and spaced from each other, ribs connecting said flanges and ribs extending downwardly from the lower flange.

8. A feeder for ingot molds comprising a the first flange, ribs connecting the flan es around its upper end, a second annu ar flange around the feeder and spaced from the first flange, ribs connecting the flanges and ribs extending downwardly from the lower face of the lower flange and adapted to support the feeder on the upper edge of the mold.

9. A feeder for ingot molds comprising a. body portion an annular flange extending around the body portion at the upper end and having a beveled inner face a second flange extending around the body portion and spaced from the first flange, ribs connectin the flange and formed integral with the ody portion and with the flange and ribs extending downwardly, forming the lower face of the lower flange.

10. A feeder for ingot molds comprising a body portion having ribs on its outer peicliphery and tapering towards their lower en s.

11. A feeder for ingot molds comprising a body portion having a shoulder on the upper end thereof cutaway at intervals in forming supporting means.

In testimony whereof we aflix our signatures.
