meow-MOLD.

Specification of Letters' Patent.

Application led September 9, 1913. Serial No. 788,882.

To all whom it may concern:

Be it known that I, CHARLES W. LUMMis,

a' citizen of the United States, residing at `Worcester, in the county of Worcester land Commonwealth of Massachusetts, have invented a new and useful Improvement in Ingot-Molds, of which the following, to-

getherwith the accompanying drawing, 1s

' y. ings have setA to allow them to be taken out Y permanent `molds have set, the plugs may be removed andv to provide a perm of the molds. In some cases permanent molds have been used, the bottoms of these plugged openings so that, after the castings the castings pushed out through the 'tops of the molds. This i's an undesirable construction as it is difficult to make the plugs fit properly, the resultV b/eing that fins are formed on the bottoms of the castings so`as to cause them to bind in the molds and make them difficult, to remove. It is desirable to pour the castings or ingots in permanent ,cav1t1es'4 and 5. Thelower edges of the side 'walls of the strainer fit closely againstl molds in order to save the labor of dismanl tling and reassembling the molds after each pouring.

One object of this invention, therefore, is

lanent ingot mold so constructed that the ingots may be removed therefrom withoutv opening or dismantling lany part of the mold.

In order tosave time, labor and space, it

"is also desirable to pour a plurality of the simultaneously, and another Aobject ingots t to provideV an improved of the invention is form of ingot mold which will permit thisV to be done. The form .of mold to be described. hereafter vas illustrating the inventionis designed for the simultaneous'pouring of two ingotsgkit is apparent, however,

being provided with that by increasing the number of ingot cav' ities in the mold, the number of ingots'whichmay be poured simultaneously will be correspondingly increased.

Other objects and advantages will appear from the following description taken in connectlon with the accomp' ying drawing, in which- Figure lis an elevation of an ingot mold with 1ts. strainer constructed in accordance with my invention; Fig. 2 is a plan view of the mold and strainer shown in Fig. l; Fig. 3 is a vertical sectional view on 1the line 3.-?, of Fig. 2; Fig. 4 is a vertical sectional view of the strainer and the upper extremity of the mold on the line 4-4 yof Fig. 2; and vFig. 5 1s a hor1zontal sectional view on the Patented Aug. 1,1916.

gether. A bottom plate 8 is fastened against the lower ends'o'f the sections 1, 2 and 3 by screwsv 9, this bottom plate serving to close the lower ends of the cavities -4 and 5.

-Strengthening ribs 10 are vformed' on the outer facesof the outerl sections land 2.

A strainer 11 rests upon the top of the sectionsA '1, 2 and 3 of the mold for the purpose iwf-directing the molten metal into the the tops of the sections 1, 2 and 3 andthe walls are solid or imperforate to obstruct the escape of molten metal over the outer edges of the mold and away from the ingot A horihas a number of Vopenings-14: located above the cavities 4 and-5 for directing the molten metal into these cavitie's Pins 15 serve t0 position the strainer properly upon the sections 1, 2 and 3 vofthe-mold The ingots 16 are formed by pouring molten metal into the strainer 11, the metal flowa space'common t0 the upper ends of all ofl said cavities, whereby the overflow Athere:- from may be rendered available as a hold for withdrawing the ingotsfrom .the cavii ties. Y

7 Thecoinbinatio'n with an ingotmold lproviding a plurality of ingot cavities, of a metal delivering memberl spaced above and common to all of said cavities, and means vides a hold for pulling said ingots f1om 'tlie cavities.

9. An ingot mold providing `a plurality of permanent ingotcavities having contracted` lower ends, and removable means surrounding the upper ends of sald cavities tor forming a hold by which the ingots may be withdrawn simultaneously from said cavities.

10. An ingot mold providing a plurality of permanent ingot cavities, a chamber commonto the upper endof allef said. cavities in which the overflow metal therefrom is confined, andl removable means adapted to Vexpose the metal constituting such overflow,

whereby the latter is rendered available as a hold for simultaneously withdrawing all the ingots from said cavities.

11;-A The combination with an' ingot mold providing a plurality of ingot cavities, of a metal delivering member spaced above and common to all of said cavities, having delivery openings directly above each cavity,

and the tops of said cavities for confining the overflow metal therefrom.
