CORE-SEAT FOR PlPE-FLASKS.
SPECIFICATION forming part of Letters Patent No. 469,747, dated March 1, 1892.
Application filed March 26, 1891.
To all whom it may concern.-
Be it known that I, REESE MORGAN, a citizen of the United States, residing at Bellevue, in the county of Campbell and State of Kentucky, have invented a certain new and useful Improvement in Core-Seats for Pipe- Flasks, of which the following is a specification.
I The object of my invention is to provide a core-seat for pipe-flasks which will permit the ready removal of bead-rings or flanges; and the invention consists in the construction and. arrangement of parts hereinafter described and claimed.
In the drawings, Figure 1 is a View, partly in section, of a twin pipe-flask, showing the sand, pattern, bead-ring, and core-seat in position. Fig. 2 is a sectional view of a portion of a twin pipe-flask, showing the sand, the casting, and the core-seat. Fig. 3 is a perspective view of a cap for locking the coreseat in position. Fig. 4E is a view, partly in section, of a portion of a twin pipe-flask, showing the sand, the pattern, a flange-pattern,- and a core-seat adapted for use in casting flanged pipe. Fig. 5 is a view, partly in section, of a portion of a twin pipe-flask, showing the sand, a flanged pipe, and a supplemental core-seat adapted for use in casting flanged pipe.
A represents a twin flask B, the sand; 0, a pattern; D, a bead-ring; D, a flange-pattern; E, the core; F, the pipe; G G, core-seat bodies; H, a shaft on which the core-seat bodies are mounted; I, a crank for rotating the shaft; J, a cap having a squared socket adapted to take over the squared head of the shaft and engage with the sides of asquare opening in the base-plate, thereby locking the core-seat bodies in their working positions, and K a base-plate rigidly secured to one part of the flask and provided with openings under the chambers of the flask, into which the core-seat bodies may take.
The core-seat bodies G are provided with the usual tapering openings g, adapted to receive the core-prints of the patterns and the cores. They are also provided upon the reverse sides with receptacles g, adapted to receive the bead-rings or flange-patterns.
The surfaces of the core-seat bodies which take intothe openings in the base-plate are Serial No. 355M265, (No model.)
curvilinear, and the bead-rings and flangepatterns are adapted to take over and rest upon the curved surface. The under or bearing surface of the bead-rin gs or flange-patterns is curved to correspond with the surface of the core-seat bodies, thereby permitting the latter to be rotated and their position reversed without forcing the bead-rings or flange-patterns out of their position.
The operation is as follows: The core-seat bodies are turned to and secured in their working position. The pattern is placed in position, its core-seat taking into the annular tapering opening of the core-seat body. The bead-ring is slipped over the pattern in the usual way and rests upon and is supported by the core-seat body. The sand is then rammed, the pattern withdrawn, and the shaft turned a half-revolution, thereby reversing the coreseat body. Reversing the position of the coreseat body removes the support for the beadring and leaves it free to fall into the receptacle g, from which it may be discharged by again giving the shaft a half-revolution, thereby returning the core-seats to their working position. WVhen the casting is made, the upper flat surfaces of the core-seat bodies serve as chill-plates for the lower end of the casting.
In casting flanged pipe it is better not to chill the flange. This may be avoided by using the receptacle as an extension of the mold for such pipe. For this purposeI employ a supplemental core-seat L, having an annular flange Z, adapted to take into the rethe flange-pattern is removed the space between the supplemental core-seat and the wall of the receptacle is packed with loam and the shaft turned so as to bring the supplemental core-seat into its working position.
I claim 1. The combination,with a pipe-flask, of a shaft and one or more core-seat bodies carried by the shaft and adapted to rotate therewith to bring the core-seats into alignment with the centers of the molds, substantially as and for the purpose specified.
2. The combination, with a pipe-flask, of a ceptacle g and be centered thereby. After base-plate having openings under the chambers of the flask, a shaft, and one or more core seat bodies mounted upon the shaft adapted to rotate therewith and to take into the openings in the base-plate, substantially as and for the purpose specified.
3. The combination, with a pipe-flask, of a shaft and one or more core-seat bodies carried thereby, the core-seat bodies being provided with tapering openings adapted to serve as core-seats and. with pattern-receptacles adapted to receive a bead-ring or flange-pattern, substantially as and for the purpose specified.
4. The combination, with a pipe-flask, of a shaft, one or more core-seat bodies carried by the shaft and adapted to rotate therewith, and means for locking the core-seats in position, substantially as and for the purpose specified.
5. The combination, with a pipe-flask, of a bead-ring, a base-plate with openings under the chambers of the flask, a shaft, and one or more core-seat bodies mounted upon the shaft and having curved surfaces adapted to take into the openings of the base plate, substantially as and for the purpose described.
6. The combination, with a pipe-flask, of a bead-ring, a base-plate secured to one part of the flask and having openings under the chambers of the flask, a shaft, one or more coreseat bodies mounted upon the shaft and having curved surfaces adapted to take into the openings in the base-plate, and receptacles adapted to receive a bead-ring or flange-pattern, substantially as and for the purpose specified.
7. The combination, with a pipe-flask, of a centered thereby, substantially as and for the purpose specified.
8. The combination, with a pipe-flask, of a shaft, one or more core-seat bodies mounted upon and revolving with the shaft and having curved surfaces, and a bead-ring or flangepattern having its bearing surface correspondingly curved, substantially as and for the purpose described.
