FEEDER FOR INGOT MOLDS.

Application filed February 15, 1924. Serial No. 698,090.

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 lVashington, 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 adapted to be sup ported on the upper end of the mold and rigidly supported thereby and also to 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 in which the supporting means are so arranged that the feeder will be rigidly supported on the upper end of the mold in the event that the bore of the mold is of a diameter greater than the'exterior diameter of the body of the feeder.

A further object of our invention is to provide a feeder of this character which is simple in structure and effective in operation and-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 a mold showing a feeder embodying our invention su ported by the upper end of the mold.

igure 2 1s a vertical transverse sectional view of Figure 1.

Figure 3 is a top plan view of Figure 1.

Figure 4 is a perspective view of an ingot mold showing a modified form of feeder supported within the upper end of the mold.

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

Figure 6 is a vertical transverse sectional view of a mold showing a modified form of feeder supported on the upper end thereof.

Referring now to the drawings, 1 represents the ingot mold and 2 the feeder; The body portion of the feeder 2 on each of its sides is provided with an outwardly extending rib 3 which extends from a point adjacent one end to the opposite end, this rib as shown in Figures 1, 2 and .3 of the drawings has its inner end of the greatest thickness and gradually tapering towards its outer end as indicated at 4. While we have shown one rib on each side of the body portion of the feeder it will be understood that two or more ribs may be employed on each side or one broad rib on each sidewithout departing from our invention.

When the bore of the mold 1 is approximately the diameter of the body portion of the feeder, the feeder is placed in the mold in the position.shown in Figures 1 and .2 with the lower flat ends 5 of the ribs 3 resting upon the upper edge of the mold. However should the bore of the bold be of a diameter considerably greater than that passed into the bore of the mold until the outer beveled face 4 of the ribs engage the bore of the mold where it is firmly wedged and held against lateral movement during the pouring operation the same as when placed in the'mold with the opposite end therein as shown in Figures 1 and 2 of the drawings.

In the modification shown in Figures 4 and 5 the feeder 6 on its sides is provided with outwardly extending ribs 7 the upper thicker end 8 being flush with the upper edge of the feeder. The outer face of the ribs are beveled as indicated at 9 and extend downwardly to a point below a central point of the feeder and having a shoulder 10 formed at their lower ends. In this form the feeder is placed in the mold as shown in Figure 5 and as the bore of the mold and the exterior diameter of the body portion of the feeder are approximately the same the shoulder 10 rests upon the upper end of the mold. However should the diameter of the bore of the mold and that of the body por tion of the feeder vary to any extent the ribs will enter the mold and engage the tapered outer face 9 and wedge in the mold.

In the forms shown in Figures 1, 2 and 3 and those shown in Figures 4 and 5, when it is desired to extend the feeder into the mold to an great extent a smaller feeder 1Q5 can be use and thus allow it to enter the bore of the mold and wedge therein by the beveled face of the ribs.

In Figure 6 the ribs 11 of the feeder lg are stepped as indicated at 13 forniihg a series of horizontal shoulders which are adapted to rest upon the upper edge of the mold and firmly support the feeder therein. In this form, llke that shown in Figures 4: and 5 when it is desired to extend the feeder into the mold any great distance a feeder of small diameter is employed and thus the feeder can be supported on any of the shoulders carried b the ribs according to the relative size 0 the feeder and the bore of the mold.

Having thus fully described our invention what we claim is 1. A feeder for ingot molds comprising a body portion and tapering ribs carried by the outer face of the body portion.

2. A feeder for ingot molds comprising a. body portion and tapering ribs carriedby all of the sides of the body portion.

3. A feeder for ingot molds comprisingba body portion and taperin ribs carried y the outer periphery of the ody portion and forming ofl sets at their inner ends.

4. A feeder for ingot molds com rising a body portion, tapering ribs carrie by the outer periphery of the body portion and commencing at one end and terminating at a. point beyond a central line of the feeder.

5. A feeder for ingot molds comprising a body portion, tapering ribs carried by the sides of the body portion and forming ofi' sets at each end.

6. A feeder for ingot molds comprising a body portion and tapering stepped ribs carried by the outer periphery of t e body portion.

7. A feeder for ingot molds compris' a body portlon having tapering stepped rlbs commencing at one end of the feeder and terminatmg beyond a point of the central line of the feeder.

8. A feeder for ingot molds comprising a body portion having tapering ribs on all four sldes and commencing at one end and terminating beyond a central line of the feeder.

9. A feeder for ingot molds comprising a body portion having tapering stepped ribs and havin one end flush with one end of the feeder an the other terminating beyond a central line of the feeder.

10. A feeder for ingot molds comprisin a body portion having tapering ribs carrie by the outer periphery and having one end flush with one end of the feeder and the other end terminating beyond a central line of the feeder.

In testimony whereof we aflix our signatures.

BLOOMFIELD H. HOWARD. ERNEST J. TURNER.
