CASTING- IEOR FEEDERS FOR .INGOT DIOLDS.

Application filed February 9, 1924. Serial No. 691,739.

.To all whom it may concern:

lVashington, District of Columbia, and

, Pittsburgh, in the county .of Allegheny and tate of Pennsylvania, have invented certain new and useful Improvements in (last ings for Feeders for Ingot Molds, of which the following is a specification.

Our invention relates to improvements'in castings for feeders for ingot molds.

The object of our invention is to provide a casting for forming ingot mold feeders made of plastic material by forcing it through a casting having a passage therethrough corresponding to the form of feeder.

Another object of our invention is to pro ed with integral ribs and having an inner wall of approximately the same contour whereby a perfect feeder is formed by forcing the plastic material through said casting by a plunger such as shown in the drawings of this application.

A further object of our invention is to provide a specially shaped casting adapted to form a correspondingly shaped feeder and having certain arrangement of walls hereinafter more fully described.

In the accompanying drawings c Figure 1 is a vertical sectional view of a casting carried by the lower end of the cylinder in which the plastic material is compressed by forcing it through the casting.

Figure 2 is a horizontal sectional view taken on the line 22 of Figure 1 showing the casting.

Figure 3 is a similar view of a slightly modified form of casting. 4

Figure 4 is a view similar to Figures 2 and 3 showing a still further modified form of casting.

Referring now to the drawings 1 represents the cylinder in which is arranged the plunger 2 for compressing the refractory material in the cylinder and forcing it through a casting as will be hereinafter more fully described. The refractory material is fed into the cylinder below the plunger in any desired manner and the lower end of the cylinder has attached thereto a section 3' carrying a spreader 4 which is adapted to spread the refractory material before it passes to the casting. Carried by the lower end of the section 3 is a section 5 which has at its lower end, an annular outwardly extending flange 6 to which is bolted the outer section 7 of the casting by means of the bolts 8. This casting section has its inner periphery provided with four inwardly bellied walls 9, 10, 11 and 12 which are connected at each corner by three 'out wardly curved walls 13, 14 and 15 which are arranged on a smaller arc of a circle than the inwardly bellied walls. The upper endsv of all of these walls are slightly beveled as indicated at 16 for the purpose'hereinafter more fully described.

The spreader 4 has a downwardly ex tending cylindrical member 17 having an internally screw-threaded opening 18 and fitting against the lower end of the said cylindrical member is a second member 19 of the casting which has four inwardly bellied walls 20, 21, 22 and 23. which are arranged in the same are of a circle as that of the walls 9, 10, 11 and 12 These inwardly bellied walls 20, 21, 22 and 23 of the casting member 19 are connected at the corners by the straight walls24, 25, 26 and 27. The upper edges of these walls, carried by the casting section 19 are beveled as indicated at 28 whereby the passage 29 between the casting members 7 and 19 has a flared upper end to receive the plastic refractory material and compress the same during' its passage between said casting members.

In the modification shown in Figure 3 the casting member 7 is arranged with walls exactly like that shown in Figure 2 of the drawings and like reference numerals indicate likeparts. The casting member 19, however has four straight walls 30, 31, 32 and 33 connected by the straight walls 34, 35, 36 and 37.

In the modification shown in Figure 4, the casting member 7 is provided with the four inwardly bellied walls 38, 39, 40 and 41 and each provided with the outwardly curved wall 46 intermediate their ends and forming the supporting ribs as will be readily seen by reference to the application herebefore mentioned. The inwardly bellied walls 38, 39, 40 and 41 are connected by the straight walls 42, 43, 44 and 45. In this wardly bellied Walls oppositely arranged and an inner member having correspondingly arranged outer Walls.

2. .Acasting for feeders for ingot molds,

comprising an outer member having in- Wardly bellied, oppositely arranged Walls and an inner member having outer Walls approximately of the same shape. a

A casting for feeders for ingot molds comprising an outer member having inwardly bellied Walls oppositely arranged and connected by oppositely arranged curved Walls, curved in'the opposite direction and an inner member having outer Walls of approximately the same shape as the inner Walls of the outer member.

4. A casting for feeders for ingot molds comprising an outer member havin four inwardly bellied inner Walls each Wal connected by three curved Walls curved in the opposite direction and the inner member having outer Walls of approximately the same shape as the inner Walls of the outer niemben 5. A casting for feeders for ingot molds comprising a member having four inwardly bellied Walls connected by outwardly curved walls arranged in a different are of a circle and an inner member having straight walls connected at the corners by short curved Walls.

In testimony whereof We aflix our signatures.
