SPECIFICATION forming part of Letters Patent No. 433,079, dated July 29, 1890.

Application filed AprillQ, 1890. Serial No. 348,608. (No model.)

To all whom it may concern.-

Be it known that we, SAMUEL L. HALSEY and WILLIAM MCGHIE, citizens of the United States, residing at New Decatur, in the county of Morgan and State of Alabama, have invented anew and useful Mold for Molding Sash-Veights, of which the following is a specification.

This invention relates to molds for molding sash-weights, and has for its object to construct a device of this class which shall possess superior advantages in point of simplicity and general efficiency.

The invention consists in the improved construction of the said molds, which will be hereinafter fully described, and particularly pointed out in the claim.

In the drawings hereto annexed, Figure 1 is a perspective view of one-half of a mold embodying our improvements, showing also the bottom plate of said mold in position for operation. Fig. 2 is a longitudinal sectional view of the mold complete, taken through one of the compartments of the said mold. Fig. 3 is a transverse sectional view taken on the line 3 3 of Fig. 2. Fig. 4 is a transverse sectional View taken on the line at 4 in Fig. 2. Fig. 5 is a perspective detail view of a. sashweight manufactured in one of our improved molds. Fig. 6 is a perspective detail view showing the bottom of the mold detached.

Like numerals of reference indicate like parts in all the figures.

The mold which forms the subject of our present invention is what is known as a chillmold. It is constructed of iron, in the usual manner of this kind of molds, and is composed of two parts or sections, both of which are constructed exactly alike and each of which is designated by 1. Each of the sections 1 is provided with two longitudinal grooves or recesses, (designated, respectively, by 2 and 3,) and from each of said recesses a vent-groove 4 extends to the upper edge of the mold. Between the recesses or compartments 2 and 3 is formed a flow-channel 5 for the admission of molten iron, said channel be in g enlarged atits upper end to form'the pourhole 6. Lateral branch channels 7 connect the central channel 5 with the compartments 2 and 3, near the upper and lower ends of the latter, respectively.

The compartment 3 of each section 1 of the mold. is provided near its lower end with a truncated projection 8, of suitable dimensions to reach the wall of the opposite compartment when the two sections 1 1 are placed together in position for operation. Each of the compartments 2 and 3 is provided with grooves or recesses 9, extending from their lower ends to the lower edge of the mold-section 1. l0 designates a bottom plate, which is provided with truncated conical projections 11, adapted to enter through the openings formed by the opposing recesses 9 of the mold and having oppositely-beveled upper ends adapted to bear against the under sides of the projections 8. The latter, in operation, serve to form the eye or opening through which the sash-cord is inserted and connected with the sash-weight, the said cord being extended through the opening formed in the extreme upper end of the weight by the truncated cores.

The edges of the sections 1 of the mold are provided with lugs 12 to enable the parts to be fitted together. The outer sides of the mold-sections are provided with handles 15, by means of which they may be conveniently manipulated.

The operation and advantages of the invention will be readily understood from the foregoing description, taken in connection with the drawings hereto annexed. The mold-sections are placed together, the bottom plate 10 placed in position, and the molten metal is then poured through the opening 6 into the channel 5, whence it passes into the compartments 2 and 3 of the mold. The cores 8 and 11 serve to form the eyes in the weights, as already described, and it will be observed that by each pouring a pair of weights are formed which may be afterward readily separated.

lleretofore it has been customary to mold sash-weights in ordinary sand molds. This has been objectionable, partly on account of the expense of this class of molds and partly on account of the defective castings, which have always been more or less rough, notably around the eyes for the attachment of the saslrcords, the result of which has been that said cords have been quickly cut and abraded, causing the weights to become detached. By

our improved molds smooth and perfect castings may be manufactured at a less expense than heretofore. Another advantage is that the molds, being of precisely the same size, there will be no perceptible difference in the weight of the castings.

Having thus described our inventiomwhat We claim is In a chill-mold or making sash-Weigh ts, the combination of two similarly constructed parts or sections, each having a longitudinal groove or recess provided with a vent-groove at its upper end, an intermediatepour-channel connected with said recess, an integral eye-core located near the lower end of one of said recessss and extending to the wall of the
