ABSTRACT:
A tension rod positioning apparatus and method for C-type clamps and Vises including a shaped threaded rod inserted into a shaped threaded hole on an engagement collar. When the shaped rod and shaped hole are aligned, the rod may be freely positioned within the collar. When the shaped rod is inserted into the collar and turned, the rod engages and turns the engagement collar. The engagement collar includes an external thread sized to fit an internal thread on a clamp base. In this manner, the rod may be inserted and then turned in one direction to both engage the engagement collar and increase the clamping pressure. After clamping, the shaped rod may be turned in the opposite direction to loosen the clamping pressure and disengage the engagement collar. Once the rod and collar have been disengaged by aligning the shaped rod and shaped hole of the engagement collar, the length of the rod may be freely moved within the engagement collar to reposition the clamp for the next operation.
