MEANS FOR MAKING METALS DENSE IN LIQUID STATE.

Specification of Letters Patent.

Patented July 12, 191G.

Application filed August 16, 1909. Serial No. 513,175.

To all whom it may concern:

Be it known that I, WILLIAM B. BABY, a citizen of the United States of America, and a resident of St. Petersburg, Russia, my post-office address being Isaacs Place, 7, have invented certain new and useful Improvements in Means for Making Metals Dense in Liquid State, of which the followin is a specification.

y invention relates to means for casting ingots and other articles in rotating molds, and has for its object the production of such articles in a quick and expeditious manner, while at the same time causing the metal through the action of centrifugal force to V be increased in density and to be freed from provided with suitable anti-friction slag, gases and other impurities.

ith these ends in view, the invention consists in the novel details of construction 20 and combinations of parts more fully hereinafter disclosed and' particularly pointed out in the claims.

Referring to the accompanying drawings forming a part of this specification in which like letters refer to like parts in all the views :Figure 1 represents a vertical sectional view, taken on the line A-B in Fig. 2, of an apparatus suitable for carrying out my invention; Fig. 2, is a plan view of the parts shown in Fig. 1; Fig. 3, is a sectional view of said parts taken on the line CD of Fig. 2; Fig. 4:, is a plan view of a modified structure suitable for cast-ing pipe; Fig. 5, is a vertical sectional view of the parts shown in Fig. 4, taken on the line 'GHI in Fig. 4; F1 6 is a sectional view taken on the line F, of Fig. 7, of a further modification suitable for casting stripsof metal of various cross sections; and, Fig. 7, is a plan view of the parts shown in Fig. 6.

Referring to Figs. 1 to 3, a suitable m'asonry foundation is shown to which is securedas by the bolts W a foundation late alls V, on which rests the lower end of a shaft to, the upper end t of which carries a suitable supportto which is secured by bolts the rotating horizontally disposed disk or wheel i, provided with the vertical ring like rim S aving the horizontally inturned edge e, and an extended outer edge on which rests the ring 1" surrounding the rim S, as shown. A circular hollow channeled plate w is supported-in the masonry and fitted w1th the anti-friction balls y, against which takes the outer rim of the disk p, as illustrated.

Supported by the disk p and held down from vertical movement by the inturned edge e are a plurality of box like, preferably tapered molds a disposed along the radii of the disk p, and having their enlarged open ends disposed near the center of said disk. Between these molds are a plurality of sector shaped wedges d, which prevent the sidewise movement of the molds and above theirinner ends are the sector shaped wedges which securely hold said ends from rising, as will be readily understood. These wedges f are firmly bound together by the band K, the ends of which are detachably secured together, as "illustrated in Fig. 2. A tapered refractory lined pipe provided with a channel 0 occupies the center and is secured to the disk 39 as shown; and

leading through the refractory bricks g into the open ends of the molds a, are the channels i which also connect with the channel 0.

m represents spaces for the escape of gases etc., between the open ends of the molds and the bricks g.

The operation of the apparatus so far described is as follows: The metal is poured and enters the molds a through the channels 0 and 1', while the disk 2) and molds are given a very rapid rotation through any suitable means, not shown. During this rotation the band '1 prevents the rim S from breaking under the enormous centrifugal strains to which it may be subjected, and the band K prevents the wedges I" from leav ing their positions. In the mean time the molten metal is forced toward the outer closed ends of the molds a and there compacted so to speak, or rendered more dense under the action of the centrifugal force to which it is subjected. This force in tending to move the heavier metal particles radially outward and also by displacement causes the lighter particles of slag to move in toward the center, thereby freeing the metal from its impurities, while at the same t me any gases that may be disengaged by this action may escape through the spaces m. After the molds a have received their allotted quantity of metal the rotation of the disk 79 is increased in order to obtain better results while the metal 'is'hardening, and this rotation is kept up until the metal assumes a dull redcolor. After the metal has cooled, some of the wedges d and f are removed, the molds a lifted from the disk p and the r ingots extracted. 7

said disk. The outer edge of the disk a between which are wedges h to ,takes against a plurality of balls 6 held in the groove of a suitable circular plate u secured to the masonry, while in the circular groove '21 fit a plurality of rin sections f,

%10ld them in place. In this form of my invention, the molds b are radially disposed, as illustrated, but as shown to the left in Fig; 5 with their partially closed ends located near the center of the circle instead of near its circumference. The open ends of these molds are closed by the rin sections 7'', and the metal enters through t e passages mt connecting with the passages 0, while the gases pass out of the passa es. Z shown in dotted lines in Fig. 4 whic inner ends of said molds. 6 represents ring sections for securely holdin the outer ends called into action.

of the molds in place, whi e 9, represents slots through the vertical rim of the disk a to permit the removal of the ingot or mold when desired. K represents a core in the mold for making pipe. The operation of this pipe casting mechanism is the same as that above disclosed and neednot be here repeated, beyond stating that the bell end of the pipe which is outward will be rendered more dense and freer' from impurities through the action of centrifugal force, than would be the case if no such force was An important advantage exists,-however, in this form of my invention, over the first form, in the fact that the molds may be. stripped by simply pulling out the wedge 12., shifting the sections. f so 'as to. uncover the ends ofthe molds, and then after the runners and s rues are severed a sli ht rotation of the sk will force the molded article throu h the opening This action permits t 1e operation to be practically continuous for only the runners and bricks 11. need be removed, when the molds are again closed and metal allowed to enter.

Referring nowto Figs. 6 and 7, wherein is shown a means for casting strips'of metal; the same general construction as that'above is disclosed. The metal enters the passage a at the center of the rotating disk; flows along the passa e a in the brick m; and enters the circ ar mold cavity 6, Fig. 6, of any desired cross sectional shape. As the metal rises in the cavity b, the gases escape through the upper passages 03 located above the upper portion Z" of the brick runners m. When the metal appears in this last mentioned passage, the pourmg 1s communicate with the said stopped, but the rotation of the disk is continued until the metal is quite hard, when the wedges f" are withdrawn, and the annular parts 9" between the halves Z of the brick'runners m, are removed; whereupon said halves Z may be withdrawn.

The clamping ring 2' is removed as well as the sector plates K, when the molded tails except as may be required. by the claims.
