JAMES THIERRY, on DETROIT, MICHIGAN.
MOLD FOR CASTING CAR- WHEELS.
SPECIFICATION forming part of Letters Patent No. 256,410, dated April 11, 1882, Application filed January 11, 1882. (No model;)
.To all whom it may concern Beit known that I, JAMES 'THIERRY, of Detroit, in the county of Waynefand State of Michigan, have invented new and useful Improvements in Means for Casting Gar-Wheels; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying draw ings, which form a part of this specification.
The nature of my invention relates to certain new and useful improvements in molds for casting car-wheels, by means of which a large proportion of the labor attending this class of work is avoided and a more perfect and desirable result is obtained.
My invention consists in the peculiar construction and combination of fully hereinafter described.
Figure 1 is a vertical central section of my improved metallic mold, showing chill, metallic center core, and sprue-basin in place. Fig. 2 is a like view of the sprue-basin detached. Fig. 3 is an elevation of a larger center core than the one shown in Fig. 1.
In the accompanying drawings, which form a part of this specification, A represents the bottom of my improved metallic mold, which is provided with a series of holes'to receive steady-pins a, and with a shoulder, I), to hold the chill B in place. This chill is made in the usual manner, except that its lower edge is provided with a series of pins coincident and to engage with said holes, or vice versa. The center of this bottom is provided with a hollow thimble, 0, through which the metallic center core, 0, is inserted. This thimhle on its innerend is provided with a flange, c, which engages with the recess in the top of the bottom; and when a larger center core is desired, as shown in Fig.3, this thimble should be changed for one the internal diameter of which corresponds with the external diameter of the base of suchlarger centercore. The core is slightly conical in shape, the more readily to withdraw it froin the hub of the wheel when cast. This center core is inserted from the bottom, and when in place is supported upon a bar or lever, D, which is pivotally secured, as at d, and provided at its outer extremity with any suitable locking device at e to prevent accidental displacement.
parts, as more E represents the cope or upper half of the mold, provided with a flange, it, against which, the upper edge of the chill rests, and said chill is secured to this top by a series of bolts, m. This topis also provided with a series of sprueholes, a, slightly conical in shape, as shown, and with a recess into which fits the beveled upper end of the center core, also as shown. The hub of this top is provided with a shoulder to engage with a corresponding projection,
0, upon the bottom of the metallic receivingbasin F, the bottom of which is provided with a recess, 8, to embrace the hub. The bottom of this basin is provided with a series of sprueholes, a, coincident with the sprue-holes n, and these holes are partially in the shape of inverted cones, so that at the point of juncture between the holes a and a the cross-section of the sprue will be the smallest. All thejoints in this mold should be sufficiently tight as to prevent the molten iron from running into or through them, and cores of any suitable character can be put in in the usual manner, as when sand molds are employed.
To prepare the mold for casting, the interior surface thereof is coated evenly, and of sufficient thickness to secure the result, with a coating of molders hlacking, facing, plaster-ofparis, clay-wash, or fire-clay, or other analogous substance, leaving the inner face of the chill uncovered. The center core is likewise so coated. The top of the mold is put in position on the bottom, and the molten liquid is poured into the receiving-basin and finds its way into the mold through the sprue-holes. When the casting is cooled the receiving-basin is struck with an upward-glancing blow, which breaks the sprues at their smallest area. The
top is then removed and the rest or lever D xo dent openings, haringtheir smallest openings at the adjoining faces of the cope and basin, substantially as and for the purpose specified.
In witness that I claim the above as myin vention, witness my signature this 20th day or December, 1881.
JAMES THIERRY.
In presence of- H. S. SPRAGUE, E. SoULLY.
