TOOL FOR SEPARATING CHAIN LINKS A tool is disclosed herein for use in chain link roller assembly and disassembly which includes an elongated lead screw having a threaded shaft manually turned by finger lever or wrench nut through a support member. A pair of jaw members operate as a movable vise having one end of a jaw pivotally connected to the support member and one end of the other jaw pivotally connected to a travelling nut in threadable engagement with the lead screw shaft. The midsections of the jaws are pivotally coupled in scissors fashion with their free ends terminating in toothed link engaging elements cooperating to releasably couple with spaced-apart chain links in a strand for releasing strand tension between the links when the jaws are drawn together by actuation of the lead screw.
