ABSTRACT:
A coupling structure includes a coupling member having a cylindrical, axially slotted end with a cylindrical opening extending therethrough and perpendicular thereto having an axis of generation parallel to the sides of the slot and including a conical surface, a conical member within the opening having a conical surface in contact with the opening's conical surface and threaded structure for axially adjustably securing the conical member in the opening. A tapered liner may surround the slotted end of the coupling member and a threaded insert may be provided over one end of the opening for receiving an end of the conical member. One embodiment includes one conical surface in the opening and one conical member provided within the opening. A second embodiment includes two separate conical surfaces in the opening along with two separate conical members in opposite ends of the opening connected by and axially adjustable along a liner member. A coupling method includes securing a coupling member having a slot in one end thereof to a second member by passing a conical member into the slot transversely of the coupling member to expand the one end of coupling member in a recess in the second member while urging the coupling member into the recess. One embodiment includes passing a single conical member into a conical opening in the slot. In a second embodiment, conical members are provided in both ends of the opening in the slot.
