METHOD FOR RECONDITIONING RIVETLESS CHAIN LINKS

摘要

RECONDITIONED CHAIN LINK AND METHODOF RECONDITIONING SAMEABSTRACTA novel reconditioned worn chain link with a bodyand opposed ends has a slightly increased cross-section atits mid portion which has less tensile strength than a neworiginal link as a result of heat treatment but less overalllength while maintaining identical pitch. The method forreconditioning includes the steps of applying intenseconcentrated heat to the mid portion of a worn link topermit reforming and compressing at least one end toward theother to shorten said link slightly a predetermined distanceto restore its original pitch.
