- To all whom t may oon/cem: i, f Be it known that BLooiir'inw H. Howf Ain) and ERNEST J. TURNER, citizens of the 4United States, j residing, res tively," at e Washington, Districtof Coliiinbia, 'and Pittsburgh, in the county of Alleghen 'and State of Pennsylvania, have invente ods and Apparatus for Making Ingot-Mold cctioii. y
@urinvention' relates to. im rovements in method and ap aratus for ma ing sectional inet mold fee ers.
"1 object of our invention is to provide a. methd and means whereb a section or` sections of an ingot mold fee' er of plastic material by forcing it through a die having a passage corresponding to the section of the feeder.
Another object of our vide a method and die for making ingot mold :feeders` in which the sections when formed singly or in multiple will have the contour of a perfect feeder when the predetermined number of sections are assembled. y A further object of o'ur invention is to provide a diein which the endsare made so as to form the sections ofthe feeder with the interlocking faces.
' A still further object of our invention is to provide a method and a die 'of this charinvention is to proacter which is simple in construction and operation and having certain details of structure and combination of parts hereinafter more fully set forth.
In the accompanying drawings Fi ure 1 is a vertical sectional View of .a cy inder and glung'er showing our improved die carrie by the lower end.` Y y Figure -2 is a bottom plan view looking 1n the direction'of the showing therdie having a number of passages for simultaneously making sections to form a complete feeder when assembled.
Figure 3 isa similar view to Figure 2 showing the dieA having two passages for making a two sectionv ingot mold feeder.
Figure 4 is a view similar'tofFigure 2 showing a four passage die -for forming a uted ingot mold feeder. v
Fi re 5 is a view similar to Figure 2 siiomng a die to form asquare feeder each Y die torni one side of the 4feeder whereby cer-- tain new and useful Improvements in Metlb" of whichy the :followingy is -a specimay be' forned' arrow of Figure 1' f i i. moor-Mom rmnnnsl sei-iai ivo. season I the iointof the several sections are arranged:
at t e corner of the square feeder. Figure 6 is an enlarged plairview of =f0ur die sections secured together and showing the plungers .for com ressing plastic material .;n ach section to orm a circular ingot mold ee er.
form of die. l A Figure 8 is 'a .crosssectional view taken 'on line 8-'8 of 'Figure 7.
Figure` 9 is a'` plan 'view of a still modified form of die and forming one of the sections of an ingot mold feeder.
Figure 10 is 'a plan view ofa portion of the die showin a V-shaped partition for forming the enge of the sections with interlocking edges. y r 'Y Figure 11 `is a, plan view vrsimilarto Figure 10 showing a curved" partition for forming the ends ofthe sections with` interlocking edges.
Referring now to the drawings 1v represents the cylinder in which is arranged a plunger 2 for com ressing the refracto material in the cylinder and through the die as will be vhereinafter more fully described. The refractory material is. fed into the cylinder below the plunger in any desired manner. The lower end of =the cylinder'has bolted thereto a section 3 carryfLV ing a spreader 4 which is adapted to spread and break up the refractory material before' its passage to the die. Carried by the lower end of the section 3 is a section 5 which has at its lower end, an annular outwardly ex'-' tending flange 6 to :which is boltedl a die section 7 by means of the bolts 8." This die section `has its ,inner peri hery beveled as.A
ILA,v AND rERN'VES'I? J'.
forcing it Figure 7li's a plan view of a 'modified member 12 thereto. This die member on its y outer periphery' is beveledl as indicated4 at 13 and whereby the passages 14, 15, 16jaiid- 17 are flared pression of the ends of the-passage. The inner and outer die members -7 and 12 are connected at proper intervals with vertical and 21 which form the four passages 14,.' 15, 16 and 17. These partitions extend in theI upper end of the die members to lower end. o

tracted when the sections are being formed in the die so that when the feeder section ,or sectionsof suflicient'length have been formed, vthe plunger or piston 2 is stopped and' the table 22 is` also stopped While the sections are cut off in anydesired manner t a point close to the lower ends of the les. i A
In the modification shown in Figure 3 of the drawings only two partitions 24 and 25 are provided therein making two passages 26 and 27 whereby a two section feeder is formed. y,
In Figure 4 we have shown the dies of a fluted form as indicated at 28 and showing three lpartitions 29, 30 and 31 whereby a three section feeder is formed.
In Figure 5 we have-shown a square die having the partitions 31, 32, 33 and 34 arranged at the corners so that each, section of the feeder is practically one side of the feeder.
In Figure 6 instead of making the die in one piece we have shown it made in four sections 35, 36, 37 and 38 which may be secured together in any desired manner or may be used separately to form a single section in Which event a plunger 39 is arranged in a receptacle above the die section which operates through a rod 40. By this structure it' will be seen that we are able to make the sections singly or-in a series of 1, 2, 3 and 4 or more. "The same principle could be ap'- plied to the form shown in Figure 1 Instead of having the die of a single piece and having the partition integral, the die sections could be made as shown in Figure 6 and the single plunger used to force the refractory material out through the four passages forming the four feeder sections.
Having thus fully described our invention what We claiinis- 1. A. method offorming sectional ingot mold feeders comprising a die and means .for yforcing plastic material through the die forming asection a number of which are adapted tjo form a complete ingot mold feeder".

' method of forming ingot mold feeders consisting of forcing. plastic material through dies having ipenm s therein to form `a number of sections W ich when assembled form a complete feeder, the abutting faces of which form an interlocking joint.
4. A die for forming ingot mold feeders comprising a member having a passage therethroughprovided with vertical partitions whereby refractory material is forced through the passage between the partitions forming several sections to form a complete feeder when assembled.
'5. A die for ingot mold feeders' compristherethrough provided with' artitions to which the plastic material isforced and said passa of a shape to form a complete ingot mo d feeder. l
6. A die for making ingot mold feeders comprising a plate having passages therethrough forming sections, said passages of a shape' to form a complete ingot mold feeder.
7. A die for making ingot mold /feeders comprising a plate having a series fof passages therethrough, each passage .forming one portion of an ingot mold feeder.
8. A die for making ingot mold feeders comprising a series of passages therethrough and having flared upper ends, said passages of the same area as thc completed ingot mold feeder.
9. Av die for making ingot mold feeders comprising a series of sections secured together and each section having a passage therethrough and means for forcing the plastic material through the several sections..
10. die for making ingot mold feeders comprising a lplate having a passage therethrough .and vflared upper ends, partitions dividing the passage into a number of smaller passages and means for forcing the plastic material through the die and whereby several sections are formed which when combined, form a complete feeder.
In testimony` whereof, we affix our signatures.
