Application filed. November To all whom it may concern:
Be it known that we, BLOOMFIIELD H. HOWARD and ERNEST J.- TURNER, citizens of the United States, residing, respectively, at Washington, 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 used in the manufacture of iron or steel ingots and has for its object the prevention of holes or seams in the upper end of the ingot known as piping and at the same time produce a feeder which will reduce segregation to a minimum. v
Another object of our invention is to provide a feeder made of refractory material and having a metal strengthening means extending around a portion of the feeder above the mold, and at the same time provide means whereby this metal strengthening means may be readil placed on the refractory feeder so that it can be removed and used on other refractory feeders; also to provide a reversible feeder.
A further object'of our invention is to provide a feeder of this character in which the metal strengthening means serves as a support for the feeder within the upper end of the ingot mold.
A still further object of our invention is to provide a simple, cheap and effective feeder of this character having certain details ofstructure and combination of parts hereinafter more fully pointed out.
In the accompanying drawings:
Figure 1 is a perspective view of an ingot mold showing our improved feeder applled thereto.
Figure 2 is.a transverse vertical sectional view of Figure-1.

view of a still further modified form of feeder.
Figure 8 is a top plan View of Figure 7. Figure 9 is a perspective view of a circu; lar mold showing a fluted refractory feeder having the metal supporting and strengthening band applied thereto:
Figure 10 is a transverse vertical sectional view of a modified form emplo ing the principle shown in Figure 4 of the rawings.
Figure 11 is a top plan view of a modified form of the principle involved in Figure 10.
Figure 12 is a transverse vertical sectional view of a still further modified form.
Referring now to the drawings, 1 represents the mold and 2 the refractor feeder, which as shown, is made of tubu ar form and of a contour to correspond with the bore 3 of the mold. This feederof refractory material may be made round, square or any desired shape to fit any form of mold, as
the shape thereof forms no part of this invention. The upper and lower'ends of the refractory feeder are beveled as indicated at 4 and 5, and surrounding the upperend of the refractory feeder is a metal supporting and-stren hening band 6. This band.
as shown in igure 2 of the drawings, has
its interior bore slightly tapering so that item be forced on the feeder 2 and frictionally held.
From the foregoing description it will be seen that we have produced a feeder of refractory material, the upper end above the mold being strengthened y the metal band 6 and which also serves as supporting means for holding the refractory feeder within the upper end of the mold. From Figure 2 of the drawings it will be seen that the exterior diameter of the refractory feeder 2 is the same or slightly less than the bore 3 of the mold 1, in order to allow it to freely pass within the bore of the mold. By this structure it will be seen that after the feeder has been used in casting the ingot, the metal band 6 can be removed and aced upon an other refractory feeder. It is of course understood that refractory feeders for in ct molds are never used more than once, but y I havin responding form, and theband 8 arranged to closely fit the exterior diameter of the .refractory feeder and frictionally held thereon in the same manner as that described in respect to Figures 1 and 2. p
In Figure 4, the mold 1 is constructed the same as that shown'in Figures 1 and 2, and the metal band 9 has its interior bore 10 at its upper end of a' diameter greater than the bore 11 of the mold, and the interior bore of the metal band9 is tapered inwardly as indicated at 12 so that its lower end is of the same diameter as that of the bore 11 of the mold. The feeder 13 is of a cylindrical, form and made of refractory material and has its exterior. diameter at its upper end tapered outwardly as indicated at 14to correspond with the taper 12 of the band '9 whereby the feeder 13 is supported by the taper 12 of the band 9 and the band 9 is'su-pported upon the upper edge of the mold.
By the structure described in respect to Figure 4 it will be seen that the refractory feeder 13 is readily placed within the metal band 9 and supported thereby and can be readily removed for the insertion of a new refractory feeder. v
In Figure 6, .the band 15 is made of circular form to correspond with the circular bore of the mold 1 and the refractory feeder 16 is made circular andthe same principle is employed for supporting the feeder in the band as that shown in Figure 4.
Referring now to Figures 7 and 8, the re- ;fractory feeder 17 has'its interior bore of the same diameter throughout its length and its exterior diameter gradually increasing from its lower end 18 to its upper end 19.
This makes the exterior diameter of the.
lower end of the feeder slightly less than the diameter 20 of the boreof the mold 1.-
The band 21 has its interior diameter slightly tapered as indicated at 22 -whereby the band can be readily slipped on the lower end of the feeder 17 and forced upwardly to the position shown in Figure 7 where it is tightly held upon the feeder and strengthens that portion of the feeder above the mold, and also forms means for sup orting the feeder within the upper end of t he mold.
In Figure 9 the same principle is applied, but a fluted feeder 23 is emgloyed having the tapered outer diameter, an the band 24 has the tapering fluted inner diameter whereby the band is wedgd upon the feeder the same as that shown in Figure 7. a
In Figure 10 we-have shown the band 25 an interior bore 26 of a; diameter consi erably' greater than the bore 27 of the mold 1, and provided at its lower end with an inwardly extending flan e 28, the .inner edge of which extends in e ose to the bore 27 of the mold 1. The'feeder 29 is of refractory material and of an exteriordiameter'to closely fit the bore 27 of the mold.
- porting the feeder within the The upper end of the feeder 29 is provided with an outwardly extending annular flange 30 adapted to rest upon the upper face of. the flange 28 carried by the band 25,-whereby. the feeder is supported within the upper end of the mold and can'be readily removed from the band.
In the modification shown in Figure 11 we have employed the same principle as that shown in Fi' re 10 except that the feeder 31 is provi ed with four outwardly 33, at a point between 1ts ends so that the feeder can be reversed in the mold 1 and supported by the band when either end of the feeder is within the mold.
Having thus fully described our invention what we claim is 1. .A feeder for ingot molds comprisin a body portion of re rectory material, an a band around only the upper end of the feeder for strengthening the sameand sup' porting it within the upper end of the mold.
2. A feeder for in 0t molds comprisin a body portion of re actory material, an
a broad metal band around only the upper,-
enccl1 of the feeder for strengthening the same mold.
3. A feeder for ingot molds comprising a body portion of refractor material, and a metal band around only t e upper end of the same for strengthening the same and supporting it in the upperend of the mold.
4. A feeder for ingot molds com rising a body portion of refractorymateria having an exterior diameter less than the bore of the mold, and a metal band around only the supporting it on the upper end of the p upper end of the same and supporting it" in the u per end of the mold.
body portion of refractory material, an metal band aroundzonly the upper end of the same and frictionally held thereon and adapted to strengthen the same and supporting the refractory body portion in the upper end of the mold.
6. A feeder for ingot molds comprising a body ortion of-refractory material, and a removable metal hand held on only the upper end of the feeder for strengthening and supupper end of 5. A eeder for ingot molds comprising. a
the mold. I
7. A feeder for ingot molds com rising a body portion of refractory materia having tapering outer walls, and a band only on the upper end of the feeder for strengthening meager the same and supporting it on the upper end of the mold.
8. A feeder for ingot molds comprising a body portion of refractory material having 5 its outer wall of the up er end enlar ed and i a metal band only on t e upper en of the feeder having a reduced lower end to engage the enlarged upper end of the feeder for strengthening the same and supporting it on the upper end of the mold.
