  • Apparatus for coupling a first member to a second member
    Patent number: 4573824
    Abstract: Apparatus for rigidly coupling a first member to a second member along a longitudinal axis is disclosed wherein one of the members carries a pair of wedges coupled to opposite threaded ends of a differential screw. The other one of the two members includes a reaction surface confronting wedging surfaces on each of the two wedges. Upon rotation of the differential screw, the wedges are moved in opposite directions to bear against the reaction surface with substantially a surface area contact to force the first and second member into rigidly coupled engagement. Upon rotation of the differential screw in an opposite direction, the wedges are positively moved in reverse opposite directions to effect uncoupling.
