To-all whom itmdi concern:

Be it known that BLOOMFIELD H. Howann 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 s ecification. I e

7 ur inventiqnrelates to improvements in reversible hottop feeders for ingot molds.

The object of our inventionis to provide I a feeder for ingot molds adapted to be supported on the upper end of the mold and at the same time provide a feeder which will prevent the formation of what isknown as piping and at the same time reduce segregation.. k J

Another object of our invention is to provide a reversible feeder adapted to fit molds having bores of different diameters and at the same time providing means whereby the feeder is rigidly supported so that it will have no lateral movement during the pour ing operation.

Another object of our invention is to provide a reversible feeder whereby ingots of different lengths may be cast in the same ingot mold.

A further object of our invention is to.

rovide a reversiblefeeder of this character in which the feeder is rigidly heldin the mold in either position and so constructed that when in'one position in the mold it extends a greater distance into the mold than when reversed.

A still further obf'ect of our-invention is to provide a simp e, cheap and effective feeder having certain details of structure and combination of parts hereinafter more fully seirforth.

In the accompanying drawings Figure 1 is a perspective view of a mold v showing our improved feeder.

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

Figure 3 is a transverse sectional view similar to "Figure 2 showing the feeder in the reversed position.

Figure 4. is a top plan view; of a sectional feeder showing a modified form of supporting rib. 2

Figure 5 is a vertical transverse sectional vlew' of F1gure4.

Figure 6 is a top plan view of a modified form of sectional feeder showin of supporting, ribs shown in Figures '1, 2 and 3. c

Figure 7 is a vertical transverse sectional view of Figure 6. t Referringnow to the drawings, 1 represents the mold and 2 the feeder. While we have shown the square feeder and a correspondingly shaped mold it will be understood that the same could be round, square,

the form rectangular or any desired shape without departing from our invention.

In Figure 1 of the drawings we have .shown the four walls of the square feeder 2 with outwardly extending .ribs 3. These ribs 3 as shown are arranged intermediate the upper and lower ends 4 and 5 of the indicated at 6 and upwardly as indicated at feeder. The outer face of the ribs 3 is bev- -eled from a 'central line downwardly as 7 and whereby they enter the bore of the mold and tightly "wedge the-feeder in the.

upper end of the mold to prevent any lateral movement in the mold during the curing operation. is beveled'outer wall of the ribs 3 allows the application of the feeder to molds in which the bore varies and yet at all times causing a wedging action to firmly hold the feeder in the mold. By reversing the feeder in the mold 'astshown in Figure 3-of the drawings, the wedging action is precisely the same. 4

In Figure '4 ofthe drawings, we have shown a rectangular feeder composed of four sections 8, 9, 10 and 11 said sections carry ing ribs 13,14, 15 and 16 each rib having a tapering wall 17 terminating in a horizontal fiat wallv 18. The ribs 17 as shown like those shown in Figures 1, 2 and 3 are arranged intermediate the ends of the feeder and whereby the reversal of the feeder in the 'mold In Figure 6 we have shown a sectional feeder made of four sections 19, 20, 21 and 22 each section carrying a rib 23, 24, 25 and 26 a rib being arranged'on the wall of eachsection intermediate its ends and having the beveled walls 27, and 28' extending towards its upper and lower ends. By this arrangement it will be seen that the feeder is reversible and locked in the mold in either of its positions by the beveled walls 27 and 28.

In the structure shown in Figures 4, 5, 6 and 7 we have provided a sectional feeder in which the section can be tightly held in this operative position when the bore of the mold is of the same diameter as the exterior diameter of the feeder or can be firmly locked together when the bore of the mold is of a greater diameter than the feeder. While we have shown and described these specific arrangements of the ribs it will be understood that two or moreribs can be arranged on each side wall of the feeder or arranged in any desired manner without departing from our invention or an annular flange arranged' around the feeder and beveled toward the upper and lower ends.

' Having thus full described our invention what we claim is 1. A reversible feeder for ingot molds comprising a body portion, ribs carried by the outer periphery of the feeder and having a tapering outer face.

2. A reversible feeder for ingot molds comprising a body portion, and tapering ribs carried by the body portion intermediate its upper and lower ends;

3. A reversible feeder for ingotmolds comprising a body portion, and ribs carried by the outer periphery of the body portion and tapered in both directions.

4. A reversible feeder for ingot molds comprising a body portion, ribs carried by the outer periphery of the body portion intermediate its ends andtapered in two directions.

5. A. reversible feeder for ingot molds 8. A reversible feeder for ingot molds.

comprising a body portion formed of a series of vertical-sections each section having ribs intermediate their upper and lower ends and having a tapering wall.

- 9. A reversible feeder for ingot molds comprising a body portion having tapering ribs on its outer walls, said ribs arranged nearer one end than the other.

10. A reversible feeder for ingot molds comprising a body portion having ribs on its outer wall, said ribs tape-ring towards the upper and lower end of the feeder and arranged nearer one end than the other.

11. A reversible feeder for ingot molds comprising-a body portion having means on its outer periphery intermediate its ends tapering towards the upper and lower end of the body portion.

12. A rei ersible feeder for ingot molds, comprising a body portion with the two ends of relative same thickness and having a section intermediate with faces beveled towards said ends.

In testimony whereof we aflix our signatures.
