No. 708,0l0. Patented Sept. 2, 1902.

TYPE CASTING.
I (Application filed Nqv. 5, 1900.) (No Model.)
UNITED STATES PATENT OFFICE.
HENRY EARTH, OF CINCINNATI, OHIO.
TYPE-CASTING.
SPECIFICATION formingpart of Letters Patent No. 708,010, dated September 2, 1902. Application filed November 5 1900. Serial No. 351480. (No model.)
type in which there are no blow-holes and is accomplished by producing a vacuum in the chamber in which the type is cast and admitting the molten metal into the vacuum while excluding the air therefrom.
In the accompanying drawings, Figure 1 is a transverse sectional view of so much of a mold as is necessary to illustrate my invention, showing the parts in the position they occupy just before the body-piece or plunger is lowered to form the vacuum-chamber. Fig. 2 is alongitudinal central sectional view taken upon line a; a: of Fig. 1. Fig. 3 is a view similar to Fig. l, but showing the bodypiece or plunger lowered.
In the operation of type-casting as heretofore carried on and as described in the aforementioned Letters Patent, as soon as the bodypiece or plunger A had traveled to its upper position to deliver the type just east to the fingers upon the end of the retracted sliding cover B of the mold it began to descend again to form the chamber in which the next type was to be cast. As a consequence, the sliding cover being retracted, air entered said chamber and caused blow-holes to be formed in the type cast therein. In my construction plunger A, sliding cover B, with its inserted steel block b, base-plate O, side members D and D of the mold, matrix E, matrix-carriage c, apron F, nipple G, choker g, and passage g for molten metal are the same in construction as in said Letters Patent, and the means of actuating said sliding cover, matrix-carriage, body-piece or plunger, and choker may be the same as the means therein described.
My invention consists in keeping plunger A in its upper position until sliding cover B has been advanced to its forward position, so as to cover the top of the mold, and matrix E has been advanced to abut against sliding cover B and plunger A, all as shown in Figs. 1 and 2, which represent the position of the parts just before plunger A is lowered. Then plunger A is lowered to the position shown in Fig. 3 and in dotted line Fig. 2, forming in chamber H a vacuum into which the molten metal enters. The type so cast are free from blow-holes.
What I claim'is- In a type-casting machine a mold consisting of side members, a sliding cover on the side members, a matrix, a carriage to advance it to cover one end of the mold, a nipple covering the other end of the mold for the admission of molten metal, a plunger between the side members, the matrix and the nipple, means for actuating'the sliding cover, and the matrix and meansfor keeping the body-piece or plunger against the cover until all the parts of the mold are closed and for then drawing it away from said cover to form a vacuum-chamber, substantially as shown and described.
