REVERSIBLE FEEDER FOR INGOT HOLDS.

Application filed February 12, 1923. Serial No. 618,545.

To all whom it may cmwem:

Be it known that we, .Bnoomrmm) H. Howmm and ERNEST J. TURNER, citizens of the United States, residing, respectively, at

5. city of Washington, District of Columbia,

and Pittsburgh, county of Allegheny and State of Pennsylvania,-have invented certain new and useful Improvements in Reversible Feeders for Ingot Molds, of which the following is a specification.

Our invention relates to improvements in reversible feeders for ingot molds.

The object of our invention is to provide a reversible feeder for ingot molds whereby the distance the feeder extends intothe mold may be readily varied, and whereby the length of the ingot can be made greater or less in the same mold, and at the same time produce a feeder' having all of the advantages of the ordinary feeder, to prevent seams and holes known as piping and also reduce segregation to a minimum.

Another object of our invention is to rovide a feeder of this character in which the same means supports the feeder in its normal and reversed position and said meansfirmly supporting the feederwithin the upper end of thecmold agamst longitudinal or lateral movement.

Another objectof our invention is to provide a feeder of this character which will v have a great number of. adjustments for varying the length of the ingot in the mold, and at the same time provide a simple, cheap and effective reversible feeder having certain details of structure and combination of parts hereinafter more. fully set forth.

In the accompanying drawings:

Fig. 1 is a perspective view of an ingot mold showing our improved feeder applied thereto. Fig. 2 is avertical sectional view of Fig. 1 showing the feeder in the reversed position in dotted lines.

Fig. 3 is a side elevation of our improved feeder.

a form of feeder.

Fig. 7 is a side elevation partly in section of another modified form of feeder.

Fig. 8 is a top plan view of another modified form of feeder.

Fig. 9 is a top plan view'of a still further modified form of feeder.

Fig. 10 is a vertical sectional view of a mold and feeder showing another modified form of feeder.

Fig. 11 is a sectional view of a mold showing in side elevation another form of feeder for having a greaternumber of adjustments Fig. 15 is a side elevation similar to Fig.

14 showing the ribs having a single slit.

Referring now to the drawings, the numeral 1 represents the ordinary ingot mold, and 2 our improved feeder in the form shown in Figures 1, 2 and 3. The feeder '2 is provided on each side with two short ribs 3 and 4, which have their upper ends 5 closer to the upper edge 6 of the feeder than their lower edge 7 are to the lower edge 8 of the feeder. By this structure it will be seen that by reversing or inverting the feeder as shown in dotted lines Fig. 2, the feeder will not extend so far into the mold and a longer ingot will be produced. 1

In Fig. 4, the feeder 9 is of a circular form and is provided with a wedge-shaped rib extending outwardly entirely around the same, and said rib being closer to the upper Y In Fig. 6 we have shown two opposite sides of the feeder 15 provided with longitudinally arranged flanges 16 and 17 placed nearer one end of the feeder than the other.

Fig. 7 shows the circular feeder 18 having a continuous rib 19 around the same, and rectangular in cross section and arranged nearer one end of the feeder than the other.

Fig. 8 shows the feeder 20 having all, four sides provided with flanges 21, 22, 23 and 24, which are of a length less than the width of the side having the corners free from engagement with the upper edge of the mold when the feeder is inserted in the mold.

In Fig. 9, we have shown the feeder with two opposite sides having the flanges 26 and 27 of a length less than the width of the sides of the feeder.

In Fig. 10, we have shown the feeder 28 having two sets of lugs 29 and 30 carried by the outer periphery and said lugs weakened as indicated at 32 and 33, whereby either set of lugs may be broken for giving four ad justments in the mold. By reversing or inverting the feeder less of the feeder will extend into the mold. By breaking of thelugs 29 and inverting the mold, a considerable more of the feeder will enter the mold, and by breaking off the lugs 30 nearly the whole feeder will enter the mold.

In the form shown in Fig. 11,-We have shown the feeder 34 with five horizontally arranged staggered rows of lugs 35, 36, 37, 38 and 39, whereby a great number of adjustments of the feeder in the mold is obtained.

In Fig. 12, in order to give further adjustments of the feeder than shown in the other figures, a fire brick or block 40 of non-combustible material may be placed on the upper edge of the mold below the ribs 3 and 4.

In Fig. 13, we have shown a.modified form of supporting ribs. In this form the ribs 41 are made comparatively thin, and of considerable length to give sutficient strength to sustain the weight, but being thin can be readily broken off so the feeder may enter the mold different distances.

In Fig. 14, we have shown the projections 42 of an elongated narrow form having their ends different distances from the ends of the feeder and having cross cuts 43 so that any portion of the lug or projection 42 may be broken to vary the distance feeder enters the mold.

In Fig. 15, the same principle is employed as in Fig. 14, except the ribs 44 are provided with a single cross cut 45.

We claim:

1. A feeder for ingot molds comprising a reversible body portion, and an integral projection carried by 'the body portion and adapted to support the feeder with either end in the mold.

2. A feeder for ingot molds comprising a reversible body portion, and an integral projection carried by the body portion nearer one end than the other and adapted to support the feeder with either end in the mold. 3. A feeder for ingot molds comprising a reversible body portion, an integral projection carried by the outer face of the body portion nearer one end than the other and adapted to support the feeder with either end in the mold and whereby a block may be placed on the upper end of the mold below the projection for raising the feeder in the mold.

4. A feeder for ingot molds, comprising a body portion, and projections carried by the outer face of the body portion and forming means for supporting the feeder within the mold and said projections weakened so that they may be broken off to allow the feeder to enter the mold different distances.

5. A feeder for ingot molds, comprising a reversible body portion, and projections carried by the outer face of the body portion and weakened so that they may be broken off to allow the feeder to enter the mold different distances.

6.
