ABSTRACT:
A torsion spring adjusting tool comprises a hexagonal shank to one end of which are welded confronting plate portions which project longitudinally outwardly from said one end, the arrangement being such that wrench means engaging said hexagonal shaped shank can apply a twisting source to a portion of torsion spring extending between said confronting plates. The confronting plates have their confronting surfaces configured to provide obliquely exposed cylindrical passageways inclined at a substantial angle one to the other so that the tool is suitable either to right-hand or left-hand operation.
