ABSTRACT:
A locking member is positionable within an opening in the arm and is likewise engageable with a post and slidable jointly with the arm along the axis of the post to initiate a clamping force. A shaft having a handle assembly on one end is threadable in the locking member and hand rotatable to move the locking member laterally relative the post to secure the arm and post together at selected positions relative each other. A spring means in the handle assembly provides increased turning torque as the lock is tightened and at a preselected designing load, a brake member overrides the washer to prevent further hand tightening.
