To all whom it may concern.
Be it known that BLOOMFIELD I-I. HOWARD and ERNnsT JIVTURNER, citizens of, the United States, residing, respectively, at
Vvashington, District of Columbia, and
Pittsburgh, in the county ofAllegheny and State of Pennsylvania, have invented certain new and useful Improvements in Castings for Feeders for Ingot Molds, of which the following is aspecification.
Our invention relates to improvements in castings for feeders for ingot molds.
The object of our invention is to provide a casting for forming feeders for ingot molds made by forcing plastic material through a passage in a casting whereby a complete feeder is made with supporting means on its outer face, this feeder corresponding with that shown in an appli walls 23 which have their lnner ends concation of even date.
Another object of our invention is to provide a casting in which a feeder may be formed having a large number of curved walls adapted to correspond with the contour of the bore of the mold, some of said curved walls forming ribs for supporting the feeder on the mold.
A further object'of our invention is to provide a specially shaped casting adapted to form a correspondingly shaped feeder and having a certain arrangement of walls hereinafter more fully described.
In the accompanying drawings Figure 1 is a vertical sectional view of the lower end of a cylinder partly broken away and showing our improved casting applied thereto.
Figure 2 is a horizontal sectional view of Figurel. V
Figure 3 is a view similar to Figure 2 showing a. modifiedform of casting.
Figure 4 is a view similarto Figures 2 and 3 showing a still further modified form. of casting. l
Figure 5 is a view similar to Figure 2 showing a modifiedform of the inner member of the casting.
Referring now to the drawings 1 represents the lower end of a cylinder in which the plastic material is compressed and is provided with an outwardly extending flange 2 to which is-bolted the flange ,3 carried by the outer casting member 4 by means of bolts 5,- This casting member 4 is provided with four inwardlybellied walls 6, 7, 8 and 9 arranged at the corners and are connected by a series of outwardly curved walls 10, 11 and 12. The outwardly curved walls 10 and 12 form the vertical.
ribs on the outer periphery of the feeder for supporting it on the upper end of the mold. The'lower end'of the cylinder is provided with a cylindrical member13 to which is bolted the inner member 14 by means of a bolt 15. This inner member 14 has each of its four walls provided withtwo inwardly bellied walls 16 and 17 connected atthe corners by the outwardly curved walls 18.
In the modification shown in Figure 3 we have shown the outer member 4 provided at the corners with outwardly bellied walls 19, 20, 21 and 22 connected by irregular nected to theoutwardly curved wall 24. These outwardly curved walls 24 form the supporting ribs on the outer face of the feeder. 'We have described one side wall but it will be understood that all four walls are constructed alike. The inner member 25 is provided at its four corners with the outwardly bellied walls 26, 27, 28 and 29 corresponding'to the walls of the outer member and each side wall isprovided with two inwardly bellied walls 30 and 31 con nected by outwardly curved walls 32.
wIn Figure 5 wehave' shown the outer member-[4 constructed exactly like that shown .in Figure 1 c and like reference numerals lndlcatelike parts. In thisform however, the inner member 42 is of a square form having four straight walls 43, 44, 45
and 46 connected at the cornersfby outwardly curved walls 47 Having thus fully described our inven-i tion what we claim is g 1. A casting for feeders for ingpt molds comprising an outer member having four outwardlyv bellied walls arrangedat the corners and connected by shorter outwardly curved walls and an inner member having walls of a difiere'nt contour.
2. A casting for feeders for ingot molds comprising an outer member having four outwardly bellied walls arranged at the corners and connected by shorter outwardly curved Walls arranged in a difierent arc of a circle and an inner member having walls of a dillerent contour. v
3. A casting for feeders for ingot molds comprising an outer member having four outwardly bellied walls arranged at the corners and connected by three outwardly curved shorter walls arranged in a different are of a circle and an inner member having four walls, each wall composed of two inwardly bellied portions.
4:- A casting for feeders for ingot molds comprising an outer member having four outwardly bellied walls arranged at the corners and connected by three outwardly curved walls arranged in a different are of a circle and an inner member having straight. walls slightly rounded at the corners.
5. A casting for feeders for ingot molds con'ipri'sing an outer member having four outwardly bellied corners connected by walls of an irregular contour and an inner member having four outwardly bellied corners connected by inwardly bellied walls.
6. A casting for feeders for ingot molds comprising an outer member having three outwardly curved walls arranged at the corners and connected by walls of an irregular contour and an inner member having two inwardly curved walls arranged at the corners and connected by two inwardly bellied Walls.
In testimony whereof allix signatures.
