ABSTRACT:
A chain stretching tool includes a generally tubular support in which at least one moveable pin-like element is supported by a piston for axial movement relative to another fixed pin-like element. The member is spring-loaded to an expanded position. A threaded bolt or other similar member is mounted in the end of the housing and is adapted to force the pin-like element to move inwardly towards the opposite element. In use, the expanded elements engage the chain links. The bolt member is then threaded into the housing and simultaneously pulls the opposite ends of the chains towards each other for appropriate chain repair and the like.
