  • Patent number: 4455054
    Abstract: A master link for a track chain has two parallel cheeks each split into a pair of mutually complementary parts with mating teeth having undercut flanks which in the tensioned chain urge them into firmer engagement with each other. The teeth have concentric arcuate ridges with a center of curvature lying beyond the axis of a pintle interconnecting the two cheeks at their ends. A track shoe or bottom plate is fastened, with some relative play in the longitudinal direction of the link, by respective bolts to the otherwise unconnected link parts.
