FEEDER FOB- INGOT MOLDS.

' Application filed April 24, 1924. Serial Nb; 7os,6s1.

T 0 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 IVashington, 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, 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 made of refractory material adapted to be supported on the upper end of the mold and a portion thereof extending into the mold and at the same time providing a feeder which will prevent the formation of what is known as piping and also reduce segregation.

Another object of our invention is to provide a reversible feeder whereby the same can extend a greater or less distance into the mold so that ingots may be cast of difl'erent lengths in the mold and at the same time providing means whereby the feeder is firmly supported on the mold and which may be used on molds of different diameters.

A further object of our invention is to provide a feeder of this character in which the supporting means form strengthening means for that portion of the feeder above the mold and at the same time providing a feeder in which the supporting means are adapted to support the feeder on the mold.

the bores of which are of a different di-- ameter and at the. same time greatly reduce the amount of material used in the construction of the feeder and yet at the same time retaining the necessary strength for supporting the feeder 'and also strengthening the outer wall.

A still further object of our invention is to provide a feeder in which the supporting means are provided with chambers into which may be placed heat retaining, or heat producing material. i

A still further object of our invention is to provide a feeder of this character having certain details of structure and combination of parts hereinafter more fully setforth.

In the accompanying drawings Figure 1 is a perspective view of our improved feeder;

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

Figure 3. is a top plan view of Figure 2.

Figure 4 is a top plan view of a modified form of feeder. V

Figure 5 is a top plan view of a still further modified form of feeder.

Figure 6 is a vertical transverse sectional view of a reversible feeder applied to the upper end of the mold showing an annular flange provided with vertical passages therethrough.

Figure 7 is a top plan view of Figure 6.

Figure 8 is a perspective view of an ingot mold showing the form of projection shown in Figure 1 of the drawings carried by the upper end of the mold and being scored so that a portion thereof can be broken ofi.

Figure 9 is a perspective view of a mold showing the feeder provided with the annular flange at the end, constructed the same as that shown in Figure 7.

Referring now to the drawings 1 'repre; sents the mold and 2 the feeder. In the drawings we have shown a rectangular mold and a correspondingly, rectangular shaped feeder but it will be understood that our invention could be applied to a round,- octa on or any other shaped mold without departlng from our invention.

The feeder 2 intermediate its ends is provided with outwardly extending projections 3 which we have shown -and provided with vertical passages 4 and 5 divided by the web 6. By this structure it will be seen that we have produced a supporting means carried by the outer face of the feeder which can extend a greater distance from the wall of the feeder so that the feeder can be supported on molds, the bores of which are varied greatly and yet at the same time retaining strength, but due to the passages 4 and 5 the amount of material used is greatly reduced and thus rewe have shaped passage 11 extending therethrough and which operates the same as the other sufficient material to retain the heat and sufficient strength to support the feeder on the upper end of the mold.

In Figure 8 of the drawings we have shown the ribs as shown in Figure 1 of the drawings at the upper end of the feeder as indicated at 15, said ribs being provided with slots or scores 16 whereby a portion of the ribs can be broken off to allow the feeder to extend a greater or less distance into the mold. In this form we have shown the ribs provided with openings 17 which allow air to enter the lower end of the hollow rib for a purpose hereinafter more fully described.

In Figure 9 we have shown the same form of flange as that shown in Figures 7 and 8 arranged at the upper end, of the feeder and indicated by the reference numeral 18. In this form the side walls opposite each vertical passage 19 are provided with openings 20 for the same purpose as the openings 17 of Figure 8.

In each and all of the forms it will be seen that the lower end of the passages in the ribs 1 are closed by the upper end of the mold when the feeder is applied thereto. This arrangement provides closed pockets or recesses into which may be placed either heat retaining material or heat generating material and the material is prevented from passing out of the passage or recess by the upper end of the mold.

In Figures 8 and 9 the heat generating material isused. The openings 17 and 20 will give sufficient draft to cause the material to properly burn.

It will be understood that the supporting means such as shown in all of the figures could be provided with openings similar to the openings 17 and 20 of Figures 8 and 9 so that heat genera-ting material could be used; in the same.

Having thus fully described our invention whatwe claim is 1. A feeder for ingot molds comprising a body portion having hollow supporting means.

2. A feeder for ingot molds comprising portion having supporting means s provl ed with vertical passages there" through. j

3.' A feeder for ingot molds having hollow ribs carried by the outer face thereof.

4. A feeder for ingot molds comprising a body portion made of refractory material having projections carried by the outer face thereof, and having vertical passages there'- through.

5. A feeder for ingot molds comprising a body portion made of refractory material having projections carried by the outer face and having vertical passages therethrough.

6. A feeder for ingot molds comprising a body portion having hollow project-ions intermediate its ends.

7. A feeder for ingot molds comprising a body portion having a projection on its outer face and having vertical passages therethrough.

8. A. feeder for ingot molds comprising a body portion having projections on its outer surface and having vertical passages therethrough and adapted to be closed by the upper end of the mold when applied thereto.

9. A feeder for ingot molds comprising a body portion made of refractory material having a projection on its outer face and passages therethrough adapted to be closed by the upper end of the mold when applied thereto.

10. A feeder for ingot molds comprising a body portion having hollow ribs carried by the outer surface.

11. A feeder for ingot molds comprising a body portion having ribs on its outer surface and having vertical passages therethrough adapted to be closed by the upper end of the mold when applied thereto.

12. A feeder for ingot molds comprising a body portion made of refractory material having vertically disposed ribs, said ribs having vertically disposed passages therethrough.

13. A feeder for ingot molds comprising a body portion made of refractory material having hollow ribs carried by the outer surface intermediate its ends.

14. A feeder for ingot molds comprising a body portion having projections intermediate its ends and having passages therethrough, said passages adapted to be closed by the upper end of the mold when applied thereto.

15. A feeder for ingot molds comprising a body portion having aprojection carried by the body portion intermediate its ends and having vertical passages therethrough, whereby the passages are closed by the upper end of the mold when the feeder is applied thereto with either end in the mold.

I 16. A'reversible feeder for ingot molds comprising a body portion having a hollow projection carried thereby intermediate its ends and adapted to be closed by the upper end of the mold when applied to the mold with either end therein.

17. A feeder for ingot molds comprising a body portion having hollow supporting means closed by the upper end of the mold when applied thereto and adapted to contain heat retaining material.

18. A feeder for ingot molds comprising a body portion having hollow supporting means closed by the upperend of the mold when applied thereto and adapted to, contain heat producing material.

19. A feeder for ingot molds comprising i a body portion having hollow supporting me In testimony whereof we affix our signatures.
