FEEDER FOR INGOT MOLDS.
Application filed November 1, 1924. Serial No. 747,326.
' 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
. lVashington, District of. Columbia, and Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented certain new and usefullmprovements in Feeders for Ingot Molds, of which the following is a specification.
Our invention relates to improvements in feeders for ingot molds used in the manufactureof iron or steel ingots and has for its object the prevention of holes and seams in 1a the upper end of the ingot known as piping and at the same time producing a feeder in which segregation is reduced to a minimum.
Another object of our inventlon is to enable a' feeder tobe made of tubular form having a perfectly plain exterior surface.
with no projections and provide means whereby the feeder can be supported on the upper end of the mold with a=predetermined portion of the feeder within the bore of the mold.
A further object of our invention is to provide a feeder of this character in which an ordinary fire brick may be used as the supporting means for the feeder.
A still further object of our invention is to provide a feeder of this character which can be adjusted in the mold so that the feeder will extend a greater or less distance into the mold, whereby ingots of different lengths can be cast in the same mold.
A still further object of our invention is to provide a simple, cheap and effective feeder of this character in which the same is firmly supported upon the upper end of the'mo-ld and having certain details of structure and combination of parts hereinafter more fully set forth. I
In the accompanying drawings Figure 1 is a .perspective view of an ingot mold showing our improved feeder supported within the upper end of the bore of the mold.
Figure 2 is a transverse vertical sectional view of Figure 1. v
Figure 3 is a perspectiveview of our improved feeder removed from the mold.
Figure Isis a vertical-transverse sectional view of a modified form of supporting means.
Figure 5 is a top plan view partly in section showing a fluted feeder and mold employing the supporting means shown in Figures 1, 2 and 3 of the drawings.
Figure 6 is a transverse vertical sectional view of a modified form of feeder.
Figure 7 is a vertical transverse sectional view employing the same supporting means as that shown in Figure 6, but showing means whereby the feeder can extend a greater or less distance into the mold.
' Figure 8 is a transverse vertical sectional view similar to Figure 4: showing means whereby the feeder can extend greater or less distance into the mold.
Figure 9 is a top plan view of a further modified form showing a kerf in the walls of the feeder to receive the supporting means.
Figure 10 is a vertical transverse sectional View similar to Figure 7 showing a modified form of recess and supporting means.
' Figure 11 is a top plan View partly in section of a fluted feeder and mold embodying the form of supporting means shown in Figure 10.
Figure 12 is a transverse vertical sectional view showing a reversible feeder and showing the form of supporting means shown in Figure 10 of the drawings.
Referring now to the drawings 1 represents the mold"and 2 the feeder. The feeder 2 as shown is of a tubular form and can be made square, round, rectangular or any desired shape having perfectly plain outer walls to allow the same to pass freely within the bore of the mold. As shown in the drawings, thefour outer walls'of the feeder 2 are provided with openings 3 extending entirely through the wall and of a shape and size to receive an ordinary fire brick 4. These fire bricks are placed within the openings 3 with their inner ends 5 flush withthe inner wall 6 of the feeder 2. It will be seen that when in this position the outer ends of the brick rest upon the upper edge 7 of the mold and firmly support the feeder within the mold. The fire bricks 4 com pletely close the openings 3 and prevent the escape of any molten metal from the feeder. In some instances it may be necessary to more completely close the openings by the use of fire clay.
The openings 3ras shown in Figures 1 and 2 of the drawings are nearer one end of the feeder 2 so that either end of the feeder can be placed in the bore of the mold so that it will extend a greater or less distance into the mold for casting ingots of different lengths.
In Figure 3 of the drawings, we have each side of the feeder provided with two openings 3 and 3 whereby the brick can be inserted in 3 when metal is being poured into the mold after which the bricks may be withdrawn and inserted in 3 which allows the feeder to follow the molten metal as it cools.
In the modification shown in Figure 4 of the drawings, instead of having the openings 3 we have provided recesses 8 which extend approximately half way through the walls of the feeder and the fire bricks 9, enter said recesses and support the feeder within the mold the same as that shown in Figures 1 and 2 of the drawings.
In the modification shown in Figure 5 we have shown a fluted feeder 10 having the four opposite walls provided with openings 11 which extend through the walls of the feeder and receive the fire bricks 12 and support the feeder on the mold in the same manner as that shown in Figures 1 and 2.
In the form shown in Figure 6, the feeder 13 has its outer face provided with a series of notches which have horizontal upper walls 14 and oblique walls 15. In this form the fire bricks 16 are arranged in an oblique position as clearly shown. When employ ing this form, the fire bricks can be placed either on their sides or on their edges, and it is understood that while in each and all of the forms heretofore described we have employed four fire bricks for supporting the feeder, it will be understood that any desired number can be used, as the number forms no part of our invention.
In Figure 7 the feeder 17 is provided with three recesses 18, 19 and 20 on each of its sides, and these recesses are constructed with the horizontal upper walls 21 and the oblique walls 22. In this form the oblique walls 22 are arranged at a less angle than the walls 15 of Figure 6.
In Figure 8 the feeder 23 is provided with two recesses 24 and 25 on each of its sides and these recesses are of a shape and size to receive the fire brick 26 and whereby the feeder is reversible in the mold and can be arranged to extend a greater or less distance into the mold.
In igure 9 we have shown a circular feeder 27 in which a number of kerfs 28 are arranged in its outer wall of a width to receive the fire bricks 29. These fire bricks can be inserted into the kerfs as shown in the drawings, or the ends of the fire brick may be inserted in the kerfs, and the feeder be supported on the upper end of the mold by the fire brick. This form as shown in Flgure 9 can have any desired number of these kerfs arranged different distances from the ends, whereby the feeder can be reversed in the mold.
In the modification shown in Figure 10 we have shown the feeder 30 provided with three recesses 31, 32 and 33 on each side and the walls of these recesses are arranged at an angle whereby the supporting wedge 32 so enters the recess that it cannot be removed without raising the feeder within ing in one direction and the notch 39 ex-- tending in the opposite direction, whereby either end of the feeder may be placed in the bore of the mold.
After the mold and feeder have been filled with molten metal, the supporting means may be removed to allow the feeder to drop further into the molds If desired the supporting means may be inserted in apertures nearer the top of the feeder as shown in Figures 3, 7 8 and 10 of the drawings.
Having thus fully described our invention what we claim is 1. A feeder for ingot molds comprising a body portion of refractory material having apertures in its outer faces for receiving supporting means.
2. A feeder for ingot molds comprising a ,body portion of'refractory material having openings in its outer faces to receive supporting means.
3. A feeder for ingot molds comprising a body portion of refractory material having aperturesin its outer faces and refractory supporting meansadap'ted to enter the apertures and supporting the feeder on the upper end of a mold.
4:. A feeder for ingot molds'comprising a body portion of refractory material having apertures in its outer faces adapted to receive a refractory supporting means.
5. A feeder for ingot molds comprising a body portion of refractory material hav ing a series of apertures in its outer faces for receiving supportingmeans whereby the feeder may extend a greater or less distance into the bore of a mold.
6. A feeder for ingot molds comprising a body portion having inclined apertures in its outer faces for receiving one end of the supporting member and the opposite ends thereof resting upon the upper end of a mold.
7. A feeder for ingot molds comprising a body portion of refractory material having inclined apertures in its outer faces, and supporting means entering the apertures and resting upon the upper end of a mold.
8. A feeder for ingot molds comprising a body portion of refractory material having inclined apertures in its outer faces, and pointed supporting means entering said apertures and supporting the feeder Within the upper end of a mold.
9. A feeder for ingot molds comprising a body portion of refractory material having a series of inclined apertures in its outer a mold.
10. A feeder for ingot molds comprising a body portion of refractory material having inclined apertures on its outer faces extending towards both ends, and supporting means entering said apertures to support either end of the feeder Within the upper end of a mold.
In testimony whereof We affix our signatures.
