Be it known that I, CHARLES G. Ros NsoN,
and useful Improvement in Apparatus for Makin Ingot-Molds, of which improvement t e following is a specification.
-'My invention relates to apparatus for Hereto'fore, so far as I am aware, formers, molds or fiaslrs'for'the manufacture of ingot molds have been'made in separable parts which were bolted or otherwise securely fastened together. I
Theobjects of my invention are two-fold', first, to produce an apparatus for molding or producing a unitary or one-piece cast steel ingot mold, the said apparatus comprising a unitary or one-piece cast steel to form an ingot mold haying stripper lugs or other projections thereon, the said cores being so disposed in said former as to per former fron'i'the ingot moldancl, second, to producea. unitary or single piece cast steel. ingot mold having stripper lugs or other A further object of my invention is to produce an ingot mold which been uniformly cooled exteriorly and interiorly. And having interior surfaces possessing the highest degree of fineness due to the fact that no part of the coreis liable to be fused by or to the molten metal, thus enabling the ready discharge of theingot therefrom and at the same time producin an ingot having even and smooth exter or surfaws.
A still further object of the invention is to enable theready escape or discharge of gas or gases f rom the interior and exterior surfaces of the ingot mold during the pouring of the ingot and after the pouring operation has been completed.
I attain these several objects by means of the apparatus hereinafter more specifically described, reference being bad to the accompanying drawings forming part hereof, lIlWlllCl'l; v
Figure 1 is a plan view of the ingot mold} Fig. 2 is a central section through lines i2-2 of Fig. 1; Figs. 3 and 4 are re spectivety blocks 7.
ig. 5 is a plan view of a plate 1 lines 8-8 of Figs. 2 and 7.
,in i the drawir s.
plan and front views of the core 4 casting funnel and runners and a sectional plan of four ingot mold formers. Fig. 6 IS a' vertical section through lines 6-6 of F g. 5. Fig. 7 is a vertical section of the ingot mold former taken at right angles to Fig. 2. Fig. 8 is a transverse section on Referring to said drawings, 1 is the usual bottom plate whereon are disposed in any suitable manner ingot mold formers or flasks 2, 3, 4 and.5. The said ingot mold formers comprise a unitary or single piece solid cast steel flash, the wall a of which is provided with trunnions Z1, the said trun nions being disposed at the sides of said flask in the usual way, whereby the said mold or flask may be readily turned. The
wall of said flask is-providcd with a series of vents or openings c which extend from the air spaces (5 to the exterior as shown in l igf'l. -The said air spaces are provided h-y longitudinally disposed channels in'opptsite sides of the chill, the upper ends of the channels remaining open to form the li'ags 8 on opposite sides of the ingot mold. Core blocks 7 are fitted in the channels toward the upper ends thereof and serve to tor-iii the lower sides of the said lugs 8. Below the core blocks 7 the mouths of the channels are 'closedzby'the vertically disposed cores or walls-1i which are preferably formed of sand', the saidcores 6 being set into the channels so that the inner surface of the mold former orchill is smooth.
Within said chill or outer wall I insert a hollow core 10 which is preferably made of sand and preferably in sections as shown The said core 10 is p0si-' tinned centrally within the chill so as to be spaced from the inner walls of the chill a distance correspondin .to the proposed .thickness of the walls of the ingot mold.
The upper end of the core 10 is capped by a ring 11. The said ingot mold formers are disposed on the plate 1. and are connected with a centrally disposed casting funnel 12 by means of the usual runners 1313 which enter the said former; preferably by the double conduits 14 at the bottom thereof.
I have called the outer flask or mold a former throughout the specification .in order to dist nguish it from the ingot mold made therein. This former may be made in the usual way castings of its size are produced.
Having described my invention, what I claim and desire to secure by Letters Patcut is:
1. An apparatus for casting, unitary steel ingot molds having stripper lugs formed thereon, said apparatus including a unitary metal mold, a centrally disposed core, and core blocks disposed within said mold near the upper end and on opposite sides thereof and adapted to form the under side of the lugs on the ingot mold, the remaining portion of the said lugs being formed by the walls of said unitary metal mold.
2. In an apparatus for making' ingot molds, the combination of an outer wall or mold, a' core centrally disposed therein, core blocks disposed in the upper portion of said mold, "ertically-disposed cores arranged in said mold between the'inn'er wall of said mold and the first mentioned core to form air spaces within the wall of said mold on opposite sides, said mold having vents lead.- ing from the said air spaces to the exterior.
3. In an apparatus for making ingot molds, the combination of. an outer wall or mold, a core centrally disposed therein, core blocks disposed in the upper portion of said mold, rvertically disposed cores arranged in said in old between the inner Wall thereof and said first mentioned core to form an air space in the wall of said mold on each of the opposite sides, said air spaces extending from said co're blocks to the lower end of said mold, and said mold having vents leading from said air spaces to the exterior.
4. In an apparatus .for making ingot molds, the combination of an outer wall or mold, a core centrally disposed therein, core blocks disposed in the upper portion of said mold "ertical cores disposed in supporting relation to said co're bloc lis 'and arranged between the inner wall of said mold and the first mentioned core. i
5. In an apparatus for. making ingotmolds, the combination of a unitary mold of cast steel, a core centrally disposed therein forming the cavity in which the ingot is cast, core blocks disposed in the upper portion of said cast steel mold constituting 'tary or single-piece cast steel former having cavities in the sides thereof for the reception of the stripper lugs, and cores so disposed in said former as to allow the casting of the ingot mold therein, permitting said lugs to contract uniformly with the remaining portion of said ingot mold.
7. An apparatus for casting unitary steel ingot molds having stripper lugs formed thereon, said apparatus including a unitary metal mold having longitudinally disposed channels in opposite sides thereof, a centrally disposed core, core blocks disposed in said channels near the upper end thereof and adapted to form the underside of the lugs on the ingot mold, the remaipm tion of the sand lugs being for t l by he walls of said unitary metal mplflka d Ve a.
tically disposed cores adapted to ,close the sides of the channels adjacent to the ingot mold.
In testimony whereof, I- have hereunto signed my name in the presence of two sub scribing witnesses. CHARLES G. ROBINSON.
In the presence of CLARENCE A. WILLIAMS, JOHN H. RONEY.
