ABSTRACT:
A coupling fixture provided with an outer ring having first and second tapered surfaces, an inner ring having third and fourth tapered surfaces, a wedge-like ring nut interposed between the outer and inner rings and axially inwardly thereof and having tapered surfaces engageable with the first and third tapered surfaces. A wedge-like ring washer is interposed between the second and fourth tapered surfaces and axially outwardly thereof and having tapered surfaces engageable with the second and fourth tapered surfaces. Screw bolts are screwable into the ring nut to expand the outer ring in diameter and contract the inner ring in diameter, each cone angle of the tapered surfaces of the washer and of the tapered surfaces engageable therewith is made larger than that of the cone angle of the tapered surfaces of the ring nut and the first and third tapered surfaces engageable therewith and makes the washer more readily removable from the outer and inner rings when the screw bolts are loosened after being tightened.
