ABSTRACT:
Improved tool for easy removal and reassembly of selective links of a sprocket chain wherein a specially designed vise tightly clamps one or more links of the chain therein. A uniquely shaped impact punch is positioned to properly hold a selected link adjacent the vise, then transmits sharp impacts to the link to more quickly and easily dislodge the selected link from the remainder of the chain. The vise includes a stationary jaw or bucking block and a relatively movable jaw with the opposed faces thereof having inwardly protruding side edges to provide a recess or clearance in the mid-section of the jaws for receiving the outwardly bowed edges of the chain link held therein, whereby a better gripping relationship may be obtained. Further, the movable jaw is caused to tilt inwardly toward the bucking block at the top upon application of clamping pressure, whereby the clamp link(s) resist inadvertent dislodgement.
