WILLIAM H. CONNELL, FPITTSBURG, PENNSYLVANIA.

MANUFAGTURE or coMPoUND INGo'rs.

Specification of Letters Patent.

Patented April 28, 1908.

Application filed August 30, 1907. A Serial No. 390,797.

To all whom 'it 'may concern:

Be it known that I, WILLIAM H. CONNELL, residing atPittsburg, in the county'of Allegheny on opposite sides of a partition, which in` some'cases was adapted-to be melted and become. 1ncorporated with the in ot andin some cases the partition was wit drawn before the metals solidified. Another method` of producing com ound ingots consisted ofl casting one body o metal and while that was lin a highly-heatedcondition, teeming the Y second ,Iiody of me`ta1 thereunto.

these methods have been'practically success- None of ful, by reason of the fact that the line of delmarcation between the two metals was sharpand distinct and in no case was there a merging or intermingling of the two bodies, so as to form an integral mass having one qiuality on one face and a different quality or klnd on the opposite face.

-The invention described herein has for its object the bringing to ether of two bodies of metal while in `a mo ten condition under such conditions that the metal of the two bodies will intermingle in the interior of the' ingot, but will-maintain their distinct characteristics at 'opposite sides of the ingot.

' The inventlon is hereinafter more fully de- 'scribed and claimed.

ed for the practiceof my In the accompanying'drawing forming a part of this specification", Figure 1- is a'lsec'- tional elevation of a form of apparatus adaptinvention; Fig. 2 is a .plan view of a suitable form or construction of ladle and-Fig..3 is a plan view of al mold having the deflector in position thereon.

In the practice of myinvent'ionthe two kinds or qualities are simultaneously teemed into the mold, care bein taken that the two streams of metal shal not intermingle. Preferably the two vstreams should be separated as widely as ossiblewhile owing into the mold, and the ilbwing together of the two lnetals will take place only after the inflowing streams have reached the-bottom of the mold or the metal" previously formed. I have found that when two bodies ofmetal and State of Pennsylvania, a citizen of the United States, have invented or dis- Aform of apparatus `of the outlets or are -thus lbrought together in a mold there will -be sufficient agitation to cat l'se a thorough commingling of the metals 1n the interior' of the ingot, and that the metals will be commingled in approximatelyequal' ortlons in and adjacent to a certain plane, )ut that the percentage will change on opposite'sidcs of s-uch plane,-that is the percentage of one metal will decrease and that the other will increase from such tothe sides `ofthe/ing'ot, where only one metal will be found. In an ingot cast in this manner no plane of cleavage will be'formed, .but one metal will be found on one side of theingot and will gradually decrease in uantityv towards the other side, while the ot er metal will correspondingly increase, thus avoiding lsharply defined zones.

In the drawing I have shown a convenient for the practice of my method, v`bul'l as regards the broad terms of the claims the inventionis not limited to such apparatus, since other means `will readil suggest themselves to those skilledin the art lfor carrying out my improvement.

ments or chambers A and B, each provided with outlet openings 2, adapted to be controlled by plugs 3. As both ports should be opened simultaneouslythe plugs are 4connected to acommonloperatinglever4. Whenit is desired to produce ingots in which the proportions of the two'metals vary, provision should be made, either by varying the sizes the movement of the plugs, so that the flow ofthe metals will yary with the proportions desired -in the ingot. It will be understood that 'compartments' and ports in the'ladle may opposite sides of the ingot. But 1t 1s preferred that the stream of'metalshouh be .80 The. ladle 1 is divided into two'compartbe so arranged that the v streams of metal will flow closely adjacent to s read out, and-to-'that end I employ de- 4 ecting plates 5 and 6 which are supported on the ingot mold. As the streams of metal strike these plates, they are spread out and deflected towards opposite sides of the mold. When these flat streams strike the bottom of the moldsor metal contained therein, they will flow laterally and meet in a plane `the position of which will vary in accordance with the relative volumes of the Ymetals.' l It is characteristic of my improved method that the two streams of metal are kept separate and distinct one from the other, and that the metals commingle only when they move in directions' at an angle to the original direction-of the streams.

In lieu of tcp teeming, bottom casting may be em loyed the metals entering the mold throug the bottom in separate streams and preferably at points adjacent to oppo-` site sides of the mold, so as to avoid any commingling of the metals except by a flow thereofina direction at an angle tothe line `or direction of iiow at the time they enter the mold.

I claim herein as my invention:

l. As an improvement in the art of making compound ingots, the method herein described which consists in teeming metals difscribed Which consists in simultaneously introducing metals varying in one or more characteristics into the' mold in distinct streams side by side and permitting the metals to move laterally in Aopposite directions and intermingle in the zone of meeting or junction.

3. an improvement in the art of'making compound lngots7 the method herein described which consists in simultaneously ouring the metals into the mold in streams aving volumes proportional to the relative quantities of the metals desired in the iinished ingot, and kee ing the streams separate and distinct whl e moving in a vertical direction.

In testimony whereof', I have hereunto set my hand..

WILLIAM H. CON NELL.
