To all whom it may concern; Be it known that Buxmr'mno H. Howann and Ennns'r J. United States,- residing, respectively, at Washington,. District of Columbia, Pittsburgh, in the county of Alleghen and State -of Pennsylvania, have invented certain new and useful Improvements in Feeders for Ingot Molds, of which the following 1 is a specification.

ur invention relates to improvements in top feeders for ingot molds. The object of our invention is to provide a feeder for ingot molds adapted to be readinserted and held on the upper, end of the mold and at the same time provide a feeder which will prevent the formation of what is known as piping and at the same time reduce segregation. Another object of our invention is to provide a hot top feeder for ingot molds having means whereby it is tightly held in the 1 upper end of the mold and-at the same time providing means to allow for any slight variation in the relative size of the bore of the mold and the exterior diameter of the feeder. A further object of our invention is to provide a simple, cheap and effective feeder aving certain details of structure and combination of parts hereinafter more fully set forth- In the accompanying drawings Figure 1 is a perspective view of a mold showing our improved feeder applied Figure 2 is avertical transverse sectional view of Figure 1. a

TURNER, citizens of the and riphery of which is of a diameter a hasa Figure 11 is a vertical sectional View of-a stilt further modified form of feeder. Figures 12 and 13 are vertical sectional views of modified forms of feeders show means for supporting the distributor plate 69 therein. v a, Referring now to the drawings, 1 represents the ingot mold and 2 the feeder. As shown, the feeder is of a shape to correspend with the bore 3 of the ingot mold and a;

while we have shown this feeder of a square form, it is understood that the invention can be applied to a feeder of any desired contour. The, feeder 2 as shown in Figures 1 and m 2 of the drawings is of a rectangular form having a passage 4-. therethrough which is of a diameter slightly less than the bore of the cylinder. The lower end of the feeder 2 has its outer wall cut away as indicated at 75. 5 forming a reduced portion 6,the outer peproximately that of the bore of the cylin er and. is adapted to enter the same as clearly shown in Figure 2 of the drawings. The cut awe portion 5 has its upper end beveled as indicated at 7 which forms a su porting surface for holding the feeder in tiie upper end of the mold.

From the description shown and described 5 in Figures 1 and 2 of the drawings itwill be seen that the beveled surface 7 of'the out away portion of the feeder forms a support for the feeder and also provides means whereby the feeder is tightly wedged in the an bore of the mold. This beveled surface 7 particular advantage when there is a slight variation in the exterior diameter of the reduced portion of the feeder and the interior diameter of the mold. This allows the feeder to enter the mold,until the beveled surface 7 tightly wedges the feeder in the upper end of the mold.

In the modification shown in-Figure 3 the mold is similar to that shown in Fi ures 1 and 2 and. the feeder 8 has the re need portion 9 of a greater length and the tapered wall 10 is also of a greater length whereby under certain conditions the feeder would more firmly wedge itself in the upper ma end of the mold. 5

In the modification shown in Fi res 4 and 5 we have shown a round mod and feeder, the tapered wall 11 starting at its vertical wall 13 which enters the bore of the mold. -,This form will perform all of the functions shown and described in respect to Figures 1, 2 and 3 and will also allow the feeder to be used in molds, the bores of which show a considerable difference in diameters.

In the modification shown in Figures 6 and 7 we have shown ,a rectangular mold and feeder 14 having-the Lbore 15 therethrough and the outer wall 16 tapering from the upper end 17 to the lower end 18 whereby the feeder is capable of being used on molds, the bores of which vary to a greater extent than that described in respect to Figures 4.- and 5.

In the modification shown in Figure 8 the feeder 19 has a central bore 20 and its,

lower end 21 reduced and terminating in the curved wall 22 which would also wedge the feeder in the upper end of the mold.

In the modification shown in Figure 9 the feeder'23 is constructed exactly like similar to Figure 5 except that it shows the inner wall of the feeder 26 extending in wardly as indicated at 27.

In Figure 12 the feeder is constructed exactly like that shown in Figure 5 except that the bore is drawn inwardly as indicated at 28 and a distributor plate 29 having openings 30 therein rests on and is supported by the tapered wall 31.

In Figure 13 he feeder 32 is constructed somewhat similar to Figure 10 except that the inner wall 33 tapers from its upper to its lower end as indicated at 34 and is adapted to support the distributor plate 35 having openings 36.

Having thus fully described our invention what we-claim is 1. A feeder for ingot molds comprising a'body portion having its outer periphery reduced towards its lower end. i

2. A feeder for ingot molds comprising a body portion having its outer periphery reduced adjacent its lower end and having a beveled wall.

. 3. A feeder for ingot molds comprising a body portion having its outer periphery tapered towards its lower end.

4. A feeder for ingot molds comprising a body portion having a tapered wall below its upper end.

5; A feeder for ingot molds comprising a body portion having its outer periphery tapered below its upper end.

6. A feederfor ingot molds comprising a bod portion having a portion of its outer perip ery tapered towards its lower end and terminating ina vertical wall.

7'. A feedenfor ingot molds comprising a body portion the upper portion of which is of a greater thickness than the lower portion and the two portions being connected b a beveled section.

8. A eeder for ingot molds comprising a body portion, the upper portion of which is of a greater thickness than the lower portion and the two portions connected by a curved section. i

9. A feeder for ingot molds comprising a body portion having a wedged supporting outer wall.

10. A feeder for ingotmolds comprising a body portion having its outer periphery tapered towards its lower end and having a tapered bore thcrethrough and a pouring plate placed in the lower end thereof.

In testimony whereof we aflix our signatures.
