MOLD.

Specification of Letters Patent.
Patented Nov. 30, 1920.
Application filed June 8, 1918. Serial No. 239,018.
To all achomz't may com-r m Be. it known that we, Jenn B. LUKOMSKI and SQN'rrIoNY LUKOMSKI, citizens of the ilnited States of America, residin at Detroit, in the county of Wayne and State of Michigan, have invented certainnew and l1SGTUTIIDPIOVQIIIQH'ES in Molds, of which the following is a specification. reference being had therein to the accompanying drawings.
This invention relates to molds, and the primary object of our invention is to mold two different articles at one time, so that the excess material ordinarily left over from. the molding of one article and returned to the cupola may be utilized in the formation of the second article, thus saving considerable time and labor by simultaneously molding the articles and reducing to a minimum the waste ofmaterial.
Another object of our invention is to provide a mold in which a a connection and a sash weight may be simultaneously produced, and provision is made whereby the Y connection may be provided with a threaded insert, and the sash weight with an eye, so that both articles are practically complete when leaving the mold.
A further object of our invention is to provide a simple, durable and inexpensive mold for the above purposes, that will be hereinafter specifically described and then claimed.
Reference will now be had to the drawings, wherein- Figure 1 is a plan of a mold in an open position, showing a core in one part of the Fm 2 is a side elevation of the mold c osed and in position to receive molten a is a vertical sectional view taken on ine IV-IV of Fig. 3;
ig. 5 is a horizontal sectional view taken on the line V--V of Fig. 2;
Fig. 6 is a side elevation of a Y connection, partly broken away to show a threaded insert; and
Fig. 7 is a plan of the same.
In the drawings, the reference numeral 1 denotes the body of the mold as having an offset portion 2 and connected to this offset portion is a stem 3 journaled in a suitable support 4. The stem 3 is supported at an angle relative to the support 4 and permits of the mold body 1 being swung from a horizontal position, as shown in Fig. 1 to a vertical position, as shown in Fig. 2, with the mold tilted in the latter position, so that molten metal will enter all parts of the mold and drive air therefrom. V
Hinged to the mold body 1 by a conven tional form of hinge 5 is a mold section 6, which together with the body 1, provide two hinged mold parts that may be easily opened and closed. The mold body 1 has a pivoted lever or latch 7 so that when the mold part 6 is swung thereon, the two parts may be locked in a closed position and safely swung to an upright position, as shown in Fig. 2. The lever or latch 7 has a cam action and firmly clamps the two parts of the mold together to establish a non-leakable connection and thus permit of molten metal being poured into the cavities of the mold.
One of the articles to be produced by the mold is a Y connection having a straight tubular portion 8 and a branch portion 9, the latter having one end thereof merging into the former and the opposite end thereof integral and in a plane with the endof the portion 8, as shown in Fig. 6. To form this Y connection, a Y core 10 is employed and to accommodate the Y core, it is necessary that the confronting faces of the mold parts be provided with cavities to receive the core and provide sufiicient clearance for the reception of molten metal around the core. Therefore the confronting faces of the mold parts 1 and 6 have straight cavities 11 and branch cavities 12.. Where these cavities merge, there are semi-cylindrical grooves 13 and said grooves cooperate in producing a flange or collar 14% on the small end of the Y connection. enlarges portions 15, which in the completed article provides an annular offset portion or seat 16 so that the end of the branch portion 9 may receive the end of a pipe or. other conduit. The large end of the Y connection also has a flange 17 which is produced by grooves 18 in the confronting faces of the mold parts 1 and 6. The seats 19 of the mold parts support the ends of the core 10 and correctly position said core relatively to said mold parts, so that when the mold is closed, there will be a space around the core 10 into which molten metal can be poured to produce the article shown in Fig. 6. Adjacent one of the seats 19 and at the top of The branch cavities 12 have the mold is a vent 20, so that air may escape from the mold when molten metal is poured therein.
In parallelism with the straight cavities 11 are weight cavities 21 and these cavities communicate with the straight cavities 11 through ports 22, said ports being angularly disposed so that it will be necessary for the metal poured into the mold tofirst .fill the weight cavities 21 and then flow into the cavities 11 and 12. of the mold. At the inner ends of the weight'cavities2l are confronting buttons 23 adapted to produce an eye in a completesash weight, and the outer ends of the weight cavities 21 are restricted by semi-circular beads 24, these beads being between the cavities. 21 and a pouring gate 25 formed by providing the confronting faces of the mold parts with flaring recesses.
In some instances, the straight portions of a Y connection may be provided withan interiorly screwthreaded insert 26. This insert is of a metal that will not fuse when the molten metal contacts therewith and the insert can be easily mounted upon the core 10 and correctly positioned thereby.
Heretofore, in producing! connection-s, it was found necessary to have the molten metal enter the lower end of the mold in order to drive air-therefrom, consequently there was a long sprue or gate metal which had to be returned to'the cupola or otherwise as waste. To utilize this long sprue or gate metal we provided the weight cavities and by tilting the mold at an inclination it is possible to drive air from the mold and have the molten metal enter all the cavities and produce complete articles.
After the molten metal has cooled and the mold been opened, the gate metal can be easily broken from the end-of the sash weight and by slightly trimming, both articles are complete.
To support the mold parts in an open position, the support it is provided with a slidable rod l that may be shifted so that the backs of the mold parts will rest thereon.
It will of course be understood that the mold can be designed for making various kinds of plumbing connections simultaneous with the formation of sash weights, and while in the drawings there is illustrated a preferred embodiment of our invention it is to be understood that the structural ele ments are susceptible to such variations and modifications as fall within the scope of the appended claim.
What we claim is A mold comprising hinged parts having the confronting faces thereof provided with cavities adapted to receive a core for the formation of a plumbers connection when molten metal is poured into the mold, said mold parts having the confronting faces thereof provided with weight cavity having a superposed angular disposed port in communication with the cavity and adapted to receive molten metal in advance thereof, beads in said weight cavity providing a restricted pouring passage into said weight cavity, and means supporting said mold at an inclination and so said mold may be swung from a horizontal plane to a vertical plane for pouring purposes.
In testimony whereof we ailix our signatures in presence of two witnesses.
