ABSTRACT:
A two part tool for aligning a pair of shafts. One tool part has two surfaces at 90 degrees from each other with each surface having a series of parallel lines, and an instrument for measuring distances parallel to an axis of a shaft from both a horizontal and a vertical direction. The second tool part provides for extending two clear parallel lined members to extend over and cover the cooperating lined surfaces on the first tool part and exhibit a Moire fringe pattern if the shafts are not angularly aligned, and an extendable target to cooperate with the instrument for measuring displacement parallel to the axis of the shaft.
