- PROCESS FOR MAKING CORES FOR MANUFACTURINGTIRE-SHOES PROCESS FOR MAKING CORES FOR MANUFACTURINGTIRE-SHOES.
- This invention relates to improvements in processes or methods for manufacturing cores or mandrels such as are commonly used in the making of outer tire-shoes of plurality of segments by hack-saws or other suitable means so as to divide the cores into suitable portions to permit the removal of one segment after another from the inner open portion of the tire-shoe after vulcani-,
- these filler-blocks or plates be secured rigidly to the ends of the segment-shaped members and as this requires drilling and tapping holes or providing dowel-pins for riveting the same in position the loss of time and which the molten metal passes from one segment-shaped compartment of the mold into another to unite the entire core-body into an integral member, the inserted plates being usually united with the corebody by the casting operatiombut being cold they do not fuse therewith.
- the corehas been cast it is placed in a suitable machine and the outside finished to impart to the exterior surface thereof the desired conformation which it is sought to impart to the interior of the tire-shoes to be formed thereon after which the core-body is broken into segment-shaped members at the points where the interposed plates are positioned.
- the interposed plates will customarily attach to one or the other of the abutting ends of the segment-shaped members but, if for any reason they do not attach themselves to the segment-shaped members, they may be afterward united therewith by suitable hold-fast devices.
- the interposition of the plates in the molds and having apertures therein to permit the molten metal to pass through the same and to unite the metal of coadjacent segmentshaped members accomplishes the function of uniting the entire core into a unitary mass during the finishing of the exterior thereof and also provides frangible joint-s between contiguous segment-shaped members of the core, which will permit the small connecting portions forming the frangible joints to be easily broken to separate the core into a plurality of independent segment-shaped members adapted to be afterward united or abutted end to end to form an annular core-body and to be held in position through the medium of auxiliary means, the resulting product being an annularly-formed core-body comprising a plurality of segment-shaped members capable of being detached when necessary and reassembled for reuse.
- the invention consists in the novel method for constructing a core, said method constituting the invention to be hereinafter more specifically described in connection with the accompanying drawings, reference to which is therein made.
- an ordinary mold is employed, which is preferably pro vided with a cavityof suitable conformatlon to form an annular core 1 having a body-portion of approximately the shape which it is desired to impart to the in- 1 teriorof the 'finishedtire-shoe, and further provided with an inwardly-extending flange 2 having on opposite faces thereof annular grooves 3, with the inner and outer walls of said groove 3 inclined as shown in -the drawings.
- there; is interposed in the cavity of the mold a plurality of'plates 4 extending across the cavity and arranged obliquely to the radii thereof and preferably arranged as shown in Fig. 1.
- These plates are provided with apertures 5 through which the molten metal which forms the core may pass from one segment-shaped cavity of the mold to an Before the casting operation.
- the device is placed in a suitable .machine such as a boring mill and the exterior thereof turned to the exact shape which it is desired to impart to the in- V terior of the tire-shoe to be built thereon.
- a suitable .machine such as a boring mill and the exterior thereof turned to the exact shape which it is desired to impart to the in- V terior of the tire-shoe to be built thereon.
- Fig. 1 are frusto-conically-formed so that the metal extending 1n these apertures ls' smaller 1n diameter at one side of the platethan at the other and thesegmentshaped members are customarily separated or broken "apart on the linewhere the thickne'ss of the metal extending from the aperture is smallest'and weakest, thus constituting a. frangible joint between adjacent and contiguous segment-shaped portions of I the preformed annular core-body.
- a method of manufacturing cores'for forming the outer shoes of double-tube pneumatic tires consisting in inserting in an annular mold-cavity a dividing medium provided with means for permitting asmall portion of the metalin'one portion of the cavity to unite with the metal in a coadjacent cavity, thereby providing a frangiblejoint between coadjacent segments of a finished core, causing said dividing medium to adhere to the end of one of said segments,
- That improvement in methods for manufacturing cores for forming the outer shoes of double-tube pneumatic t1res,'wh1ch consists in incorporating in an annular mold-cavity a plurality of apertured dividing mediums each provided with means 1 for permitting a small connecting portion of the'metal in coadjacent portions of the mold-cavity to unite through said dividing medium thereby providing a frangible joint between said coadjacent portions of the iin-
- I have hereunto set lshed core,secur1ng sald dividing mediums my hand in presence of two suscribing Wit- 10 to the ends of said core portions and subsenesses.
