FEEDER FOR INGOT MOLDS Filed Dec. 3 1924 i atented Jan. 13, 1.9259
UNITED STATES PATENT QFFICE.
BLOOMFIELD H. HOWARD, OF WASHINGTON, DISTRICT OF COLUMBIA, .ANID ERNEST J; TURNER, OF PITTSBURGH, PENNSYLVANIA.
FEEDER, FOR
Application filed December 1, 1924.
To all whom it may concern:
Be it known that we, BLOOMFIELD H. HOWARD and ERNEST J. TURNER, citizens of the United States, residing, respectively, at
5 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 fol lowing is a specification.
Our invention relates to improvements in feeders for ingot molds.
The object of our invention is to provide atubular body portion having means at its upper end for retaining the heat at the upper end of the mold and ingot to prevent piping in the ingot and also reduce seg regation.
Another object of our invention is to pro- 20 vide a feeder of this character in which the upper end of the feeder is thickened so as to provide sufficient material to retain the heat, and at the same time provide means whereby the feeder is firmly supported on the upper end of the mold.
A further object of our invention is to provide a feeder of this character which is simple in construction and has certain details of structure and combination of parts hereinafter more fully set forth.
In the accompanying drawings:
Figure 1 is a vertical sectional view of a mold showing our improved feeder applied thereto.
Figure 2 is a bottom plan View of Fig ure 1.
Figure 3 is a top plan view of a sectional feeder embodying our invention.
Figure f is a top plan view of a circular feeder.
Figure 5 is a top plan view of a sectional circular feeder embodying our invention.
Referring now to the drawings, 1 represents the mold and 2 the feeder. The feeder 2 is formed of a tubular body portion 3, having its upper end thickened as indicated at 4. The lower end of the thickened portion 4 is connected with the cylindrical body portion 3, by a concavo-convex surface 5, whereby there is a wedging action between the upper end of the mold and the feeder, regardless of the relative diameter INGOT MOLDS.
Serial No. 753,162.
of the bore of the mold, and the diameter of the thickened portion 4 of the feeder.
I11 the modification shown in Figure 3, the feeder is made in four sections 6, 7, 8 and 9 and the lower face of the thickened portion is of a concavoconvex form the same as that shown in Figures 1 and 2.
In the modification shown in Figure 4E, we have shown the circular feeder 10 with an annular flange 11, the lower face of which is of a concavo-convex form the same as that shown in Figures 1 and 2.
In the modification shown in Figure 5, we have shown a circular feeder embodying our invention, formed in four sections 12, 13, 14 and 15, each section having the thickened portion, the lower face of which is of a concavo-convex form.
Having thus fully described our invention what we claim is 1. A feeder for ingot molds comprising a body portion having a thickened portion, the lower face of which is of a concavoconvex form.
2. A feeder for ingot molds comprising a tubular body portion having a thickened upper end, the lower face of the thickened portion having a concavo-convex surface so extending from the outer face of the tubular body port-ion to the outer face of the thickened portion.
3. A feeder for ingot molds comprising a tubular body portion having a thickened upper end, having its lower face connected with the tubular body portion by a concavoconvex surface.
4. A feeder for ingot molds comprising a body portion formed of a series of sections having thickened portions at their upper ends, and the lower faces of the thickened portions having concavo-convex surfaces.
5. A feeder for ingot molds comprising a body portion of refractory material having a relatively thick portion, and a relatively thin portion connected by a concavoconvex surface.
In testimony whereof we affix our signatures.
