ABSTRACT:
A positioning collar clamping device comprising, a generally rectangular body member having a projecting portion, said member being adapted to receive a shaft through a central longitudinal opening therein, means defining a first transverse opening through said member and overlappingly intersecting with said shaft receiving longitudinal opening, a lock pin adapted to movably fit within said first transverse opening having first and second ends, said first end having a threaded surface and said second end being adapted to affect an interference fit with said shaft disposed within said longitudinal opening when said lock pin is moved in a first direction, while moving said pin in a second direction reduces and eliminates the interference fit, means defining a slot at one end of said first transverse opening, and captive nut means threadably receptive of said first end of said lock pin, said captive nut means being positioned in said slot so as to be axially immovable in relation to said first transverse opening so that when said captive nut means is rotated in one direction said lock pin is positively driven in a first direction and when said captive nut means is rotated in the other direction said lock pin is positively driven in a second direction.
