To allwhomitmay-comem:-' A

Be it known that we, BnooMrrnw Howann and Enxns'r J. TURNER, citizens of the United States, residing, respect vely, at

6 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. p I

Our invention relates to improvements in feeders for ingot molds.

, The object of our invention to prov1de a feeder for ingot molds for casting' ron 15 or steel ingots in which the heat is retained at the upper end' of the mold and thus preventholesand seams known as piping and at the same time reduce segregation to a minimum. Another'objectof our invention is to prowide a feeder of this character in which the upper endof the feeder is so contracted that the heat in its upward passage engages the walls of the feeder, and is reflected back 95 against the molten ;metal,' and prevents the rapid cooling thereof,

A further ohjectof' our inyention is to provide meahswhereby a contracted feeder can be supported on the upper end'of the Il'lOld.

' v A still further object of our invention is to" provide a simple, cheap and effective. Feeder of this character having certain details of structuie'and combination of hereinafter, more fully set forth.

- In'the accompanying drawings Figure 1 is a perspective view of our improved feeder. Figure 2--is a vertical sectionalview of a mold showing our-improvedfeeder therein. Figure? is a verticalsectional view of a. mold showing a modified form of feeder therein. 1 4 Figure 4-. is atopplan view of Figure 3. Figure 5 is a perspective view showing a. modified form of feeder'.

Figure 6 is a perspective view similar to Figure 5.showing a further modified form offeeder. Figure 7.isa vertical sectional view of a mold-showing a'modified form of feeder therein partly in section and partly in side elevatio Referring now to the drawings, 1 repreparts i Application filed November 1, 1924.

sents the mold and the feeder. The feeder 2 as shown, has: its side walls contractedltowards its upper end as indicated at 1 0, whereby the open upper end of the f eeder' is of a diameter considerably less than the lower end 4, which fits in thebore of the mold. The upper end of the feeder is provided with four outwardly extending arms 5, 6, 7 and 8 which exten outwardly heyond'a vertical line with the lower end of the feeder, and rest upon the upper end of the mold. These arms 5, 6, 7 and 8 may he scored asindicated at 9 so that they can be broken oil so as to allow the feeder to drop down into the mold after the ingot is formed and to follow the molten metal as -it cools within the'mold. Y

In the form of feeder shown in Figures 1 and lythe'walls of the feeder being contracted so that the open upper end is cone siderably less than the lower end, it will be seen that the heat from. the molten metal will strike sloping walls thereof and absorb' the heat and also reflect the heatback into the-mold against the molten metal. It-

will be seen that the heat will not readily escape'from the feeder, but will be retained to prevent piping outer wall of the feeder at its upper end -is provided with a flange 12 extending entirely there around, and in order to support the feeder within the mold in'the position shown, we provide the two rods 13 and 14 which extend under the flange-12and have their outer ends resting upon the upper end of the mold. In order to hold the two rods in the positions shown, we provide a coil spring 15 at each end. of the rods which "normally draws .them together and maintains. them under the flange at the upper endof the feeder. In this form when it is desired to allow the feeder to drop down nto the mold, as the molten metal recedes,-

as itcools, the-rods 13 and 14 can be moved from under the flange.

In Figure 5, instead of having the flange continuous, we have it cut away, which pro rides on each side the two outwardl extending

lugs

16 and 17 under whic the rods 13 and 14 would pass, and the feeder supported in the same manner as that'de ed at 22. These converging walls are provided with outwardly extending arms 22-3 which. extend out and rest upon the upper end of the mold. In this form we have employed a cover 24 which closes the upper I end of the cylindrical bore of the feeder and maintains the heat within the upper end of the mold.

Having thus fully described our invention what we claimv is 1. A feeder for ingot molds comprising a body portion having its lower end adapted to enter the mold and having its inner walls converging towards its upper end, and means carried by the upper end of the .feeder for supporting-it on the upper end of the mold.."'

2. A feeder. for ingot -molds comprising a body portion having its lower end adapted to enter the bore of the mold, and having its innerwallsconver m'ng towards the upper end. and means carried by the upper end of the feeder for supporting it on the upper end of the mold.

3. A feeder for ingot molds comprising a body portion having its lower end of a'diameter to enter the bore of the mold and having itsinner walls converging towards the upper end, and means carried by the upper end of the feeder for supporting it on the u per end of the mold.

4. A eeder' .for ingot molds comprising a body portion having its lower end of a diameter to enter'the bore of themold and having its inner walls converging towards the upper end, and outwardly extending arms carried by the upper end of the feeder for supporting it upon the upper end of the mold.

5. A feeder for ingot molds comprising a body portion having its lower end of a dianu-ter to enter the bore of the mold, and having its inner walls converging towards its upper end, and an outwardly extending member carried hi the upper end of the feeder for supporting it upon the upper end of the mold.

6. A feeder for ingot molds comprising a body portion having its lower end of a. diameter to enter the bore of the mold. and having its inner walls converging towards its upper end. andoutwardlv extending arms carried by the upper end of the feeder and adapted-to rest upon the upper end of the nuild. and supporting the feeder within the mold.

T. A feeder for ingot molds eon'iprising a body portion having itslower end of :1 diameter to enterthe bore of the mold, and having its inner walls converging towards the upper end of the mold,'and the upper end of the feeder having outwardly extending arms resting upon the upper end of the mold, and said arms scored so that they can be broken off to allowthe feeder to drop into the bore of the mold.

8. A feeder for ingot molds con'iprising abody' portion having its lower end of a diameter to enter the boreof the mold, and having its inner walls converging towards the upper end. an outwardly extending member carried by the upper end of the feeder. and rods resting upon the upper end of the mold below the outwardly extending- BLOOMFIELD H.
