MOLD.
SPECIFICATION forming part of Letters Patent No. 443,412, dated December 23, 1890.
` Application filed April 30, 1890. Serial No. 350,086. (No model.) I
To @ZZ wiz/0m it may concern.-
Be itknown that I, JOHN L. P. SPOONER, of Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Molds, of which the following is a full, clear, and exact description.
This invention relates to improvements in the construction of molds, for which Letters Patent of the United States were issued to me, dated January 7, 1890, No. 418,767, which mold is used more particularly for making compound metal ingots; and the invent-ion consists of a mold for making compound metal in gots or for other purposes, constructed all substantially as hereinafter fully de-` scribed, reference being had to the accompanying sheet of drawings, in which- Figure l represents in central vertical section a mold constructed according to this invention. Fig. 2 is a longitudinal central secion of the mold, showing the manner of making the same; Figs. 3 and 4, cross-sections on line 3 3 and 4 L3t,Fig. 2, respectively. Figs. 5, 6, and 7 are cross-sections on line 5 5, 6 6, and 7 7, respectively, of Fig. 1. Fig. 8 is a cross-section on line 5 5, Fig. 1, but showing a modification.
In the drawings, A represents the mold made, principally, of a lire-resisting material B,which material in the presentinvention consists, preferably, of plumbago, clay, and sand, and in or about the following proportions: plumbago, seven (7) parts; clay, three (3) parts, and sand, one (l) part, all being mixed thoroughly together with Water sufficient for them to properly mix, and when thoroughly mixed and in a moist and plastic condition the material is molded into the proper shape as hereinafter described.
B is a cast-iron tube or cylinder, in the upper part O of which freely fits a sleeve or thimble D, also of cast-iron, having a shoulder a to rest upon the upper end b of the tube, this upper part C of the tube and sleeve being substantially the shell and sleeve or thimble in the patent referred to. The other or lower portion E of the cast-iron tubeis embedded in the fire-resisting material B, as shown, and has at intervals of its length ap' ertures or openings d through it, which aln lows the lire-resisting material to pass th rough the same to unite and tie the inner and outer portions c and f of the fire-resisting material together, as shown in Figs. 1, 2, and 5. The lower end of this portion E of the tube is thickened somewhat, making a shoulder g on each side of the thickness of the tube, the extreme end beyond the shoulder being of wedge shape iu cross-section, as shown at 7L in Figs. l and 2.
The manner of making this mold is as follows, it being illustrated in Fig. 2. In this iigure, F is a cast-iron shell or casing, its central longitudinal opening m at its lower part being of a size or diameter to receive the tube B', the shoulder end of sleeve rest-ing on a block G, which freely its in the casing or shell, and has a central depression fnto receive the end q of a rod II. The upper part of the shell above the tube is larger in diameter internally for the reception of the ireresisting material, as hereinafter described.
In preparing the mold the tube B is rst cast of the requisite size and length and diameter and the sleeve D tted and placed therein. The rod H, of the proper length and of a diameter to iit the opening o' through the sleeve, is then placed in and pushed up through the sleeve in the tube about as shown or as desired and the whole placed in the casing or shell F, then the block G inserted, and then the casing at the block end is placed on a base or bed L, the rod Il resting in the depression n of the block G, its length being to extend up therefrom in the tube, as desired, for the required depth of the mold, as shown in Fig. 2. The fire-resisting material is then properly mixed with water as described, and, while in a plastic and somewhat moist condi tion, the casing is filled with it by putting it therein through the open end s of the casing, and a block J, placed on the top of the casing having a vertical central opening t through it, preferably of the same diameter as the internal diameter of the casing or shell and a rod or plunger K placed therein and pressed irmly down upon the plastic nre-resisting material, (the block J being held in place in any suitable manner,) which will firmly press the material down in the inside of the tube about the rod II and outside of the tube be IOO tween it and the casing and through the openings d, as shown in Fig. ,\vhen itisthen left to set and dry, and when dry the plungerblock K is removed and the prepared mold removed from the casing F, which can be done by forcing it outward by pressing forcibly against the block G until the mold is free. The rod II is then withdrawn, leaving a eentral longitudinal chamber or opening in the mold of the required diameter for the purposes required. A more or less number of apertures d through the lower portion of the tube can be made, as desired, and of any size and shape desired, it only being necessary to have suitieient openings to lie the outer and inner portions of the lire-resisting material iirmly together.
In the using ofthe mold the plastic matel. A mold consisting ot' a iire-resisting 1naterial and a tube or shell of metal, the lower portion of said tube or shell being permanently embedded in the fire-resisting material.
A mold consistingr of a lire-resisting inaterial and a tnbe or shell of metal, the lower portion of the tube or shell having apertures or openings through it and embedded in the fire-resisting material, the iireresistingmaterial entering and illing the apertures or openings. y
A mold consisting ot' a lire-resisting material and a tube or shell of metal, the lower end of the tube or shell being of wedge shape in cross-section and having shoulders and enli bedded in the lire-resisting material.
4. A mold consisting of aiire-resisting material and a tube or shellhaving .apertures or openings through it and its lower end being of Wedge shape in cross-section and having shoulders and embedded in the tirewesistiug material, the iire-resisting material entering and lling the apertures or openings.
In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
