FEEDER FOR INGOT .MOLDS. A

Application filed January 27, 1923. Serial No. 815,319.

To all whom it may concern:

Be it known that BLooMFmLD l-l. HOWARD and ERNEST J TURNER, citizens of the United States, residing, respectively, at city of Washington,District of Columbia, and Pittsburgh, county of Allegheny, State of Pennsylvania, have invented certain new and useful Improvements in Feeders for Ingot .M0lds, 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 reversible sectional feeder for ingot molds,

having all of the advantages of the one piece feeder, to prevent seams and holes known as piping and also'reduce segregation to a minimum.

Another object of our invention is to provide a sectional feeder which can be readily set up off of the mold and the several sections locked together against lateral movement, the said looking means serving as a support for the feeder, for holding it on the upper end of the mold partly in the bore thereof and having means whereby the distance the feeder enters the mold may be varied.

A further object of our invention is to provide a sectional feeder which takes up about one-fourth the space of the one piece feeder in shipment and at the sametime there isless liability of the same breaking in transportation and the breaking of one section does not destroy the entire feeder and thus obviating the greater portion of the loss by breaking in transportation.

, A still further object of our invention is to provide a simple, cheap and effective sectional mold feeder, 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 ordinary ingot mold showing our improved sec tional feeder applied thereto.

Figure 2 is a sectional view of Figure 1 showing in dotted lines the feeder in an inverted position.

Figure 3 is a transverse horizontal sectional view taken on the line 3-3 Figure 2.

Figure 4 is a vertical sectional view simi lar to Figure 2 of a modified form of feeder, in which each edge of the sections is provided with two interlocking members whereby the feeder can assume four different positions in respect to the mold, or any number of interlocking members can be used to suit the practice of the steel industry.

F igure 5 is a sectional view of an ingot mold showing the feeder in full lines, with a feeder of the character shown inFigure &, in an inverted position. v

F igure 6 is a top plan View of Figure 5 showing the feeder partly in section.

Figure 7 is a perspective view of the male and female sections in their separated relatron. Figure 8 is a vertical sectional view of an ingot mold showing a modified form of feeder in which one edge of each section is provided with a lug and the other edge with a recess.

Figure 9 is a top plan view of Figure 8 showing one corner of the feeder broken away.

Figure 10 is a top plan view similar to F igure 9 showing an oblong feeder.

Figure 11 is a top plan view of a circular feeder partly broken away.

Figure 12 is a vertical sectional view taken on the line 12-12 Figure 11.

Figure 13 is a perspective view of an ingot mold showing the form of feeder shown in F igures 4i and 5 applied thereto and showing a retaining and strengthening band holdingthe sections together.

Figure 14;. is a side ele ation showing the mold in section and showing the retaining and strengthening bands made of ordinary \VlIe.

Figure 15 is a side elevation similar to Figure 1% showing the interlocking means broken off and the retaining and strengthening bands supporting the feeder on the mold.

Referring now to the drawings 1 represents an ordinary ingot mold. having a square opening therein and in which is placed my improved sectional feeder 2 which is of a shape to correspond with the opening in the mold. The feeder 2 is made of four

sections

3, 4c, 5 and 6, the sections a and 6 are of a width equal to the width of the opening in the mold and the edges of these sections 7 are provided with square notches 7 at a point intermediate the ends of the sections. The

sections

3 and 5 are of a width to fit in between the sections 4: and 6 and each edge is enter the

notches

22 and 23.

provided with the rectangular lugs 8 of a size to snugly tit in the recesses 7 oi the sections t and 6 and are of a length greater than the thickness of the sections t and 6 whereby they extend out beyond the outer walls thereol and rest upon the upper edge of the ingot mold and supports th feeder in the bore of the mold. The lugs 8 as shown in Figure 2 of the dra vings are nearer one end of the feeder than the other, so that by inverting the feeder, it will extend a shorter distance in to the mold as shown in dotted lines Figure 2.

In the modification shown in Figures at to 7 inclusive we have shown each section 10 having each side edge provided with two uotcl'ies ll and i2 and each edeje of the section 10 having two lugs 13 and is adapted to enter the notches in the member 10 and said lugs forming supports for holding the feeder on the upper end of the mold, as described in respect to Figures 1 to 33 inclusive. The

lugs

13 and 14 shown are diii'erent distances from the cuts of the sections for a purpose which we will presently describe. The

lugs

13 and 14% are provided with horizontal notches in their upper and lower faces as indicated at 16 and 17 which weakens the lugs and allows that portion beyond the notches to be readily broken off, so that there will be no projecting portion beyond the outer wall of the feeder so that the feeder can enter the bore of the mold. As shown in Figure 4 of the drawings a considerable portion of the feeder extends into the mold but by inverting the feeder and allowing the upper lugs 13 to support it but a small portion of the "feeder will enter the mold. By breaking the upper lugs 13 of Figure 4 when in an inverted position as shown in Figure 5, a greater portion of the feeder will enter the mold, than that shown in Figure l, or by breaking ofi" the lower lugs 14 of Figure i, a still greater portion of the feeder will enter the mold.

In Figures 8. 9 and 10 instead of one section carrying the lugs and the other section having; the notches or recesses one edge of each section has a notch or notches as the case may be as indicated at 18 and the other edge of the section having a lug or lugs 19 and the edges of the sections are mitered as indicated at 20 to prevent any inward movement of the sections, when on or oil of the mold, as clearly shown in Figures 9 and 10 oi? the drawings.

ln l1 and 12 we have shown a round feeder and in which case it made of two sections but if desired could be made in three or more sections without departing from our invention. In this form the section 21 has both

edges tori

22 and 23 and the section 2 has its edges provided with the

lugs

25 and 26 adapted to As shown in the drawings these lugs do not follow the contour of the sections and thus when the two sections are brought together they will project beyond the wall of the sections and form projections to support the feeder on the mold. While we have shown this arrangement or notches and lugs it will be understood hat the same principle, as employed in Figures 8 to 10 inclusive could be used on this round form.

in Figure 115 we have shown a that retaining and strengthening band 27 extending around the mold between the lugs 13 and 14s and havii the tightening means 28 whereby the several sections forming the feeder may be tightly held together.

in Figure Li inste d oi the flat retaining and strengthening band we have shown two strancs or wire 29 which may have their ends twisted together or fastened in any desired i'i'ianner.

ln l igure we have shown the retaining band as means for supporting the feeder on the mold. In this "form the ends of the that shown in Figure 13. This I ment allows oi the adjustment of the feeder in the mold the same that described to gures ito 7 inclusive. .ziug thus fully described our inven- "iion what we claim and desire-to secure by i 1 Pat is:
