ABSTRACT:
An apparatus for aligning two rotary shafts includes a pair of jigs, each including a pair of othogonally related bars extending from a common vertex. A pair of threaded shafts extend longitudinally from the distal ends of the bars, and a plate secured to the threaded shafts serves to clamp one of the rotary shafts to the orthogonal bars. An arm extending longitudinally from the vertex of the orthogonal bars includes an indicator member extending therefrom, one of the indicator members being adjustably secured along the length thereof. The jigs are each clamped to one of the rotary shafts, rotated into confronting alignment, and the indicator members of both are precisely aligned. The tools are then rotated 180.degree.; any displacement of the indicator members indicates misalignment of the rotating shafts.
