ABSTRACT:
An apparatus for straightens long slender shafts by moving a force couple over the length of the shaft as the shaft is rotated. The force couple is applied by two or more contact points with at least two contact points being located on opposite sides of the shaft. The contact points are mounted on a movable base. A pair of parallel guide rods receive the base and restrain the base against movement in a direction perpendicular to the axis of the shaft. A lever, pivotally mounted to the base, holds one of the contact points. Movement of the lever controls the magnitude of the force couple and movement of the base relative to the shafts. The lever can be manually operated to lend simplicity to the apparatus.
