Clamp

Clamping attachment for tensile pulling device comprising:

• a pair of clamping members designed to be arranged side by side, said members being each designed to provide one of a pair of facing jaws;
• said members and said jaws being arranged to allow said jaws to grasp a member between them;
• said jaws being each provided with bores designed to be aligned when said jaws are grasping a member between them;
• a bolt member being designed to extend through said aligned bores,
• each of said bores, at their outwardly facing ends, being enlarged to provide a surface defining a cavity at the corresponding entrance to the bores,
• bearing members adjacent each end of said bolt designed to contact the respective surfaces of said cavities and to bear thereon;
• said enlarged bore surfaces being shaped to allow said bearing members to move thereover as said bolt moves over a predetermined angular range relative to said clamping members,
• said bores being made sufficiently larger than said bolt to allow such predetermined limited angular movement;
• means for allowing tensile pull on said clamping attachment on the side of said bolt remote from said jaws,
• said means allowing tensile pull comprising a conical member designed to have its wider end received between said clamping members at the end thereof remote from said jaws, and to have its narrow end project outwardly from between said clamping members at said remote end, means attached to said narrow end to allow connection of said conical member to a tensile pulling member, said clamping members at the end remote from said jaws being shaped to define a cavity to receive the large end of said conical members and to define means on which said conical member bears;
• whereby the application of tensile pull on said connection allowing means said conical member acts to spread the jaw remote ends of said clamping members.
