MOLD FOR MOLDING RADIATOR-SECTIONS.
lSPECTIFICA"IlON forming part of Letters Patent No. 581,017, dated Apri1`20, 1897.
Application filed December 9, 1896. Serial No. 615,022. (No model.)
To LZZ whom, t may concern:
Be it known that l, ORRIN BRYANT, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Molds for Molding Radiator- Sections, of which the following is a specilication.
My invention relates to an improved means for molding radiator-sections or analogous articles, whereby the core may be set in its exact position in the mold and securely held in that position, also the parts of the mold upon which the core rests are greatly strengthened and the core-is Ventilating, all of which will be fully and clearly hereinafter1 described and claimed, reference being had to the accompanying drawings, in which- Figure 1 represents a Vertical longitudinal central section through a pattern and one part of a two-part flask on or about line a a, Fig. 3, showing the iirst operation of preparing a mold for casting a radiator-section. Fig. 2 represents a Vertical longitudinal central section through a complete rnold, also on or about line a a, Fig. 3, showing the core in position and the means for securing and ventilating it. Fig. 3 is a top plan View showing the core in position in J[he lower half of the Inold and the Ventilating-openings therein. Fig. 4 represents a detached top View of the core centering, holding, and Ventilating device. Fig. 5 is a vertical central section through the same on or about line d d, Fig. 4. Fig. 6 represents a top View of a portion of a sand mold, showing one of the parts upon which the core rests and is supported, showing also a similar View of the core centering,
Fig. 7 represents a face View of one end of a pattern, showing the nipple-opening portion attached to it.
Referring to the drawings for the details of the construction, I have shown an ordinary molders iiask, constructed, preferably, of cast-iron and consisting of two parts 1 and 2. The pattern 3 is secured by screwbolts 4 to a platform 5, upon which the mold is made. The pattern, it will be noticed, represents one-half of a radiator-section, so that when a moldis inade from it in the two halves of the flask and they are put together with the core 6 in its properposition between them, as in Fig. 2, a complete mold for a radiatorsection is made. At each end of the pattern is a practically true circular opening, in which is nicely iitted the portion 7 of the pattern which forms the nipple openings and the parts of the mold upon which the core G rests. The portions 7 are turned as true as possible, and the bolts 4 pass down exactly through the center of each until stopped by the enlarged portions 8 of said bolt, which portions taper upward to their points 9. (See Fig. 1.) They are made easily removable.
The core centering, holding, and' ventilating portions 10 are adapted to fit nicely on the tapering portions 8 and are easily removable therefroin, as they form a portion of the sandvrnold and go with it when it is removed from the pattern. (See Fig. 2, where these portions are shown in their proper positions within a sand mold.)
The core supporting and Ventilating devices 10 are preferably made of cast iron. They are turned in a lathe perfectly true, and when in their proper position in a sand mold are wholly inclosed therein, so that the molten metal does not touch them. Consequently whenever a casting is made they are taken from the mold and used again.
rlhe core 6 is provided with a convex portion 11 (see Figs. 2 and 3) at each end, adapted to t in the enlarged opening 12 in the parts 10, which being exactly central holds and supports the core in its true position until a casting is made. The parts 10 being of metal do not yield or move. Consequently the core, being a dry-sand core and hard, is held rigidly in place. The core is provided with the vent-openings 13 13a, which communicate with the openings 14 through the supporting portions 10 and the openings 15 through the' mold 16, thereby allowing a free outlet for the gases generated within it to escape.
The operation is as follows: Vhen making a mold, the first thing to be done is to place one part of the ilask 2 in position over the pattern, as in Fig. 1. Then the holding, centering, and Ventilating devices 10 are put onto the tapering portions 8, substantially as shown in Fig. 1, and by the usual operations one-half of a sand mold is made in that part of the iiask. The iiask is then lifted off from IOO the pattern and turned over, the parts IO remaining in and materially strengthening the parts of the lnold in which it is inclosed and also providinga suitable outlet for the venti lation of the core. The core is now put in place, the convex portions Il fitting exactly in the cent-ral openings 12. The top portion l of the iiasl; is now put over a pattern and the other half of the mold made in the same Way. It is then set on top of the flask 2, as in Fig. 2, and securely clamped, the ventopenings 13 of'the core communicating with the 1nold-openings Il and I5, thereby afford in a perfect ventilation.
If desired, the portions S of the bolt et may be of the same diameter from the bottom shoulder to the top instead of being made tapering. I make them tapering for convenience in placing the core centering, supporting, and Ventilating device thereon or removing it.
I claim as my inventionl. In an apparatus for casting radiatorsections, the combination with the pattern, of bolts for securing it to the molding-platform, said bolts having tapering portions which extend up above the pattern, and a removable eore centering, supporting and ventilating device, adapted to lit said bolts as above set forth.
2. In an apparatus for casting radiatorsections, the combination with the pattern, of two upright bolts located centrally near each end of the pattern for scouring it to the molding-platform, the upper ends oi said bolts extending upward above it to the top of the sand inold or substantially so, and removable core supporting and Ventilating devices, adapted to fit the upper portions of said bolts and form portions of the mold with which they are removable, for the purposes described.
ORRIN BRYANT.
