FEEDER FOR INGO'I HOLDS.

Application filed December 29, 1923. Serial No. 683,505. I

To all whom it may concern:

, Be it known that BLOOMFIELD H. HOWARD and ERNEST J. TURNER, citizens of, the United States, residing, respectively, at

5 Washington, District of Columbia, and

Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented certain new anduseful Improvements in Feeders for Ingot Molds, 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 an adjustable feeder for ingot molds whereby the distance it extendsinto the mold may be varied as desired and at the same time provide a feederhaving all the advantages of the ordinary feeder to prevent piping and also to reduce segregation to a minimum.

Another object of our invention is to provide afeeder with the supporting means for giving the required strength to withstand the pressureof the molten metal from within the expansion incident to the casting of ingots and at the same time contain the minimum amount of refractory material.

Another object of our invention is to provide a fceder'of this character in which the same is firmly held in the mold in any of its adjusted positions and at the same time provide ready means for said adjustment and also provide a simple, cheap and effective feeder having certain details of structure and combination of parts hereinaftermore .fully set forth.

In the accompanying drawings:

Figure l is a perspective view of an ingot mold showing our improved feeder applied thereto.

Figure 2 is a vertical transverse sectional view of Figure 1. J

' Figure 3 is a. vertical transverse sectional view similar to Figure 2 showing a slightly 'modified form.

Figure 4 is a vertical sectional View modified form of feeder.

. Referring' now to the drawings, 1 repreof a sents the ingot mold in which is arranged our improved feeder 2 which feeder is shown rect'angularin form to fit the bore of the .ingot mold. Itwill be understood that the same could be made round, square, fluted or of any desired formto conform with the flanges can be bro .as shown in Figure 2 of the drawings.

bore of the ingot mold as the shape. forms no part of this invention.

The feeder 2 is provided with a series of horizontal ribs 3, 4 and 5 arranged one above the other and completely cncirclingthc outer periphery of the feeder. The ribs 3, 4, and 5 as shown in Figure 2 of the drawings are scored on their upper and lower faces as indicated at 6 and 7. The saidscores 6 and 7 as shown in Figure 2 of, the drawings are close to thebody portion so that the ribs or en off to allow. the feeder to extend a greater distance into the mold.

The object of extending the feeder a greater or less distance into the mold is to cast a longer or shorter ingot. In this structure it will be seen by breaking off the rib 5 the feeder willextend into the mold until the upper edge engages the flange 4. If it is desired to have the feeder extend still further into the mold -the rib 4 is broken off and the feeder will then be supported by the upper end of the mold by the rib 3. It might be under certain conditions-necessary to have the feeder extend a greater distance into the mold in which event the flange 3 s broken off and the feeder supported in the mold by any of the well known hangers used in the art.

In the modification shown in Figure 3 of the drawings the feeder 2 is provided with horizontal ribs 8, 9 and 10 arranged exactly In this form however the upper rib 8 is not cut away or scored and therefore forms a permanent part of the feeder which is never broken off. I

In the modification shown in Figure 4 none of the ribs are scored. This form could be n'lanufacturcd more cheaply than the other forms shown and accomplish the desired result.

\Vhile we have shown and described this specific manner of weakening the ribs it will be understood that the same could be aceon'iplished in other ways and we do not care to limit ourselves to this specific means whereby the ribs can be broken off.

Having thus fully dcscribed'ourinvention what we claim is:

1. A feeder for ingot molds, comprising a body portion of refractory material with 2. A feeder for ingot molds com rising a bod portion of refractory materia a series of i'agile ribs extending around the outer pgriphe'ry thereof and adapted to be broken 0 y 3. A feeder ,for ingot molds com rising a -bod portion of refracto 5; A feeder for ingot molds comprising a,

- body portion of refractory material, a series of horizontally arranged fragile ribs com- 'pletely encircling the outer periphery of the feeder and adapted to be broken-oil and spaced from the ends of the feeder.

6. A feeder for ingot molds comprising a Y body portion, a series of horizontally arv,mn-g'ed ribs completely encircling the outer periphery of the feeder and arranged one above the other, the upper rib arranged .clOser to the upper end is an the lower rib is tothe lower end of the feeder said ribs constructed to be broken 0H.

7. A feeder for ingot molds comprising a body portion, a series of horizontally ar ranged ribs completely encircling the outer perlphery of the feeder and arranged one above the other and the upper and lower faces of said ribs scored adjacent the body portion whereby they may be broken ofi.

8. A feeder for ingot molds comprisinga body portion, an outwardly extending rib adjacent the upper end and completely encircling the outer periphery of' the body portion and a series of ribs below the first mentioned rib and completely encircling the body portion and having. upper and lower faces scored whereby they may be broken 0E.

t In testimony whereof we afiix our signaures. I
