rarest eine SASH WEIGHT.

Application led September 14, 1925.

Our present invention relates generally to sash weights, and has for its primary object the elimination of certain practical or operating disadvantages due to the structure and methods of formation now enjploycd. lt is well known that in casting sash weights according to the present method, the eye or hole is left rough, frequently with cutting ridges where the mold sections join and also with square edges or shoulders, all of which soon abradc the sash cord in practice with the result that it quickly breaks and frequent repair becomes necessary.

lt has already been proposed to cast separat-e eyes in sash weights, but this adds considerably to the cost thereof and great diiiiculty is experienced in arranging the eyes in the molds so that they are uniformly set in the finished weights.

Our invention proposes to eliminate the disadvantages in the above respects by forming the smaller or bore end of the weight within a hollow cup or jack-et which may be set firmly and solidly in a mold and which becomes a part of the weight to be withdrawn from the mold with the weight and more or less permanent depending` upon the material of which the cup or jacket is constructed. This cup or jacket will have means adapted to form an eye through the weight and is preferably a stamped product formed of sheet metal, paper or other material suiiiciently strong to last at least until the cast metal sets and of a oharacter presenting a smooth inner face so that the surface of the finished weight through and around its eye will likewise be smooth and without abrasive corners, projections and the like.

In the accompanying drawing, which illustrat-es our present invention,

Figure l is a side view of the cup or jacket proposed by our invention,

Figure 2 is a vertical section taken centrally therethrough,

Figure 3 is a sectional view through a mold in which the sash weights are formed in accordance with our invention, and

Fioure 4 is a side view of a iinished sash weight.

Serial No. 56,328.

Referring now to these figures, and particularly to Figure 4, our invention proposes a sash weight l0 having around its upper smaller end a jacket 1l formed of said smooth material with an integral tubular portion l2 thereof extending transversely thereof and forming the cord-holding bore or eye of the sash w-eight. This jacket is initially stamped or otherwise suitably formed of the hollow shape shown especially in Figure 2 wherein its transverse tubular portion 12 may be plainly seen. The jacket or cup l1 is associated with the sash weight when the latter is formed in a mold and is, at this time, lled with the metal which when set in the mold, constitutes the weight. Moreover, the jacket or cup thus forms a part of the sash weight anda part which is more or less permanent, depending upon the material of which the jacket is formed. lf constructed of sheet metal, the jacket endures, and an external smooth surface is, of course desired, while if a less durable material, such as paper is used, it must have a smooth inner face and must -of course be suiiiciently strong to retain the molding and smoothing influence until the cast metal has set.

In accordance with our improved method` the cup or jacket 11 is inverted in the mold drag 13 as shown in Figure 3 within the base of the mold cavity, so that by placing the cope 14 on the drag, the molten metal may b-e poured into the series of cavities without difculty so that it will run into and fill the several cups or jackets ll.

It is thus obvious that irrespective of the material of which the cup or jacket ll is formed, it constitutes a more or less permanent part of the 'sash weight so that after the metal has set, and the weights are removed from the mold, the cup or jacket, or what is left of the cup or jacket, is removed with each weight.

In this way, our invention avoids the addition of any difficulties or disadvantages to the molding of the weights, and at the same time provides for the elimination of the disadvantages first above mentioned in sash weights as constructed at the present time as Well as in methods of manufacture Which have been used up to the present time with the object in view of elimination of rough edges adjacent to the eye of the sash 5 Weight.

Ve clamz A sash Weight comprising a jacket having an integral, tubular, eye portion, and an integral casting filling said jacket and tubular eye portion. 10 In testimony whereof We have aiiXed our signatures.
