MOLD FOR CASTING WASTE-TRAPS.

SPECIFICATION forming part of Letters Patent No. 617,396, dated January 10, 1899.

Application filed January 27, 1897. Serial No. 620,886. (No model.)

To a/ZZ whom t may concern:

Be it known that I, PETER DAvID HAY, a citizen of the United States, residing at Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Improvement in Molds for Casting Waste-Traps; and I declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention has for its object an improved mold for casting waste-traps; and it consists of the construction,combination,and arrangement of devices hereinafter described and claimed, and illustrated in the accompany- In the drawings, A denotes any suitable support or frame.

B B denote the counterparts of a two-part mold, hinged together, as indicated at b.

, C is the main or body core, removably engaged in said mold to form the body of the trap.v This core may be actuated in any desired manner, as by a threaded stem C. This core O is preferably formed with a shell O2, inclosing two chambered bodies Cs and O4, within which is located a rotatable shaft O5, with which are connected two elbow-cores D and D. the shaft C5 in any suitable manner to secure their advancement and retraction through the shell C2 of the core O, said shell being constructed with suitable orifices therefor, as indicated at c and o.

As shown in the drawings, the shaft C5 is formed with crank-arms, as indicated at c2, with which the elbow-cores are eccentrically These elbow-cores are engaged with connected, respectively. Said elbowcores might be eccentrically connected with said shaft in any suitable manner to secure their advancement and retraction.' The bodies C3 and O4 are chambered, as indicated at c3 and c, to give room therewithin for the advancement and retraction of the elbow-cores.

The mold is shown constructed with a main chamber to receive the body-core C, with` a communicating chamber to receive an auxiliary core to contact with the advanced elbowcore D, and with a communicating chamber to receive another auxiliary core to contact with the advanced elbow-core D. Thus to form the main portion of the outlet-passage of the trap I provide an outlet-core E, contacting with the advanced elbow-core D' at its inner extremity, the opposite end being connected with the stem C', so as to be simultaneously removable with the main core O.

The core D may be formed with a socket at el to receive a pin e on the core E to hold the parts together 'while the mold is being used.l

The shaft C5 may be actuated in any proper manner. As shown, the stem O is made hollow, and the outer end of the shaft is sleeved therethrough to be actuated by a hand-wheel O6 to rotate said shaft.

To form the inlet-passage of the trap, I provide an inlet-core F, having a stem F and operating-handle F2. The inner end of the core F contacts with the advanced elbow-core D. Said latter core maybe constructed With a socket at d' and the core F with a pin f to engage the socket and hold the parts in firmengagement.

The mold is journaled, as indicated at B2, upon the support A, so as to be swung thereupon to actuate the mold.

The operation of the device is as follows:

The main core O having been advanced into the mold with the outlet-core E, the shaft C5 is actuated to advance the elbow-cores D D.

The mold is then closed and swung upon its n IOO and the elbow-cores retracted, when the main core and core E may be withdrawn. The mold may then be opened and the trap removed.

The core C being made with the shell inclosing the chambered bodies C3 C4, it is evident that the shaft C and the elbow-cores may readily be engaged within said chambered parts before their engagement into the shell, when by retracting the elbow-cores the bodies may be engaged in the shell, said shell being held in place by the cap C7 at the inner end of the stem C5.

It is evident that this mold may be operated by a single attendant. The stem F of the core F rests upon the upper edge of the frame A, while the stem C contacts with the under surface of said frame. When the cores C and E have been entered into the mold, the mold may then swing downward upon its journals, when the core F may readily be entered. Then the mold has been filled with metal, the core F may readily be removed by the attendant before the mold is swung back into horizontal position. By this mold one attendant can do the work which it has heretofore required the services of two men to perform.

It is evident that inasmuch as the main core and the elbow-cores remain in the mold and form a part thereof in the act of casting the elbow-core must have a tight joint when in advanced position with the adjacent portions of the main core through which it is advanced. By making the elbow-cores tapering they will seat closely when advanced, so as to eifectually prevent the molten metal flowing into the chambers of the main core. As shown, the elbow-cores are engaged on diiferent sides of the shaft and toward opposite ends thereof.

That I claim as my invention is l. In an apparatus for the purpose set forth, the combination of a two-part hinged mold, a main core, an outlet-core, means extending to the exterior of the mold for supporting and simultaneously actuating the outlet-core with the main core, an inlet-core, and elbow-cores carried by said main core, and means for advancing and retracting said elbow-cores, substantially as set forth.

2. In an apparatus for the purpose set forth, the combination of a two-part hinged mold, a main core,an outlet-core, an inlet-core, a shaft carried by the main core, and elbow-cores connected with said shaft toward opposite ends of said shaft, said elbow-cores retractable within the main core and advanceable therethrough by the operation of said shaft, substantially as set forth.

3. In an apparatus for the purpose set forth, the combination of a two-part hinged mold, a chambered main core, an outlet-core, an inletcore, a shaft carried by the main core and projecting therewithin, and elbow-cores eccentrically connected with said shaft, said elbow-cores retractable within the main core and advanceable therethrough by the operation of said shaft, substantially as set forth.

4. In a mold for a casting with several communicating cavities, in combination with the mold for the exterior of the casting, a core for each cavity, an elbow-core for each communicating passage between the cavities, an actuating device adapted to actuate the elbowcores, and couplings between the several elbow-cores whereby they move simultaneously, the elbow-cores being located in one ofthe main cavity cores and being arranged to be projected therefrom and retracted thereinto, substantially as described.

5. In an apparatus for the purpose set forth, the combination of a two-part hinged mold, a main core, an outlet-core, an inlet-core, a shaft carried by the main core and projecting therewithin, and elbow-cores connected with said shaft, said elbow-cores retractable within the main core and advanceable therethrough by the operation of said shaft, said main core constructed with an inclosing shell, and chambered bodies to embrace said shaft and to receive the elbow-cores, substantially as set forth.

G. In a mold for the purpose set forth, the combination of a two-part hinged mold, a main core, inlet and outlet cores, and means extending to the exterior of the mold for supporting and simultaneously advancing and withdrawing one of said last named cores with the main core from the mold, substantially as set forth.

7. In an apparatus for the purpose set forth, the combination of a main core, an outletcore, an inlet-core, a shaft carried by the main core and projecting therewithin, and elbowcores connected with said shaft on different sides thereof, said elbow-cores retractable and advanceable by the operation of said shaft to contact with adjacent extremities of the outlet and inlet cores, respectively, when in advanced position, substantially as set forth.
