I Application filed March 22, 1884. (No model.)

To aZZ whom it may concern:

Be it known that 1, JOHN R. KINSLEY, a citizen of the United States, residing at Cincin nati, in the county of Hamilton and State of Ohio, haveinvented a new and useful Improvement in Molds for Making White-Metal Castings, (and according to my knowledge-and belief the same has not been in public use or on sale in the United States for more than two years prior to this application,")" of which the following is a specification. I

Myinvention relates to an improvement in molds for making white-metal castings, for hinge-tips and other purposes, withwooden cores, The wooden core is covered witha non-inflammable paint or'wash, and has a vent from its top down through the center, and also continuing throughv the pin in the mold onwhi'ch the core stands and out through the bottom oi'themold, the top opening of the vent being covered by a hood, which is formed by projections from the two 'sides of theinold, which, when closed, come together and form this hood, which prevents the'molten metal *from entering this vent, whereby the blowing whichpauses imperfect; castings is prevented,

and this" non-inflammable coating also greatly reduces the smoke and steam by which this blowing is caused, said mold being made of iron or steel, and said wash or paint being composed of one pound of molding-sand, onefourth pound of pulverized rosin, and onefourth pound of wheat -flour, .mixed thoroughly with water to astiff. paint or paste and applied with a brush to the wooden core, and then thoroughly dried in an oven or otherwise before using Figure No. 1 shows thecomhination complete, and Fig. No. 2 shows a section of the wooden core and pin on which it rests.

In Fig. No. 1; A shows the base of the mold; B B, the two sides of the mold; C, the hinge connecting these two sides. B shows the wooden core in position on the pin of the mold. E shows the pin on which the core stands. F shows the guide-pin or stop which causes the two sides of the mold to come together corcavity. H H show the two shoulders or pro.- jections which, coming together, form. the hood or vent-cover. I I show the mold'cavities for the gate through which the molten metal is poured. ,K shows the arm of the look by which the two sides are fastened together during casting.

In Fig. No, 2, I) shows a section of the wooden core. 1E shows a section of the pin on which said core stands. L shows the longitudinal vent-orifice, open at the top and extending continuously'down through the wooden core and pin on which it stands, and out through the bottom of the mold.

Ihe white-metal which I use is composed of one hundred (100) pounds of lead, twenty (20) pounds of antimony, and five (5) pounds of block-tin;- but I do not confine myself to the use of any particular metal; therefore I claim- The combination of a covered or prepared fice open at the top, with a mold having a vent communicating therewith, and'having a hood the core, substantially as described, and for the purpose set forth.
