Abstract
Abstract A crystal boule indexing fixture, the fixture comprising a frame including a pair of spaced apart, axially extending bores having parallel axes, and a pair of rods extending through the bores. A cover is hingedly connected to the frame through a hinge pin having an axis parallel to the axis of the bores, the cover being movable between a first position overlying a portion of the rods to press a crystal boule against the rods and a second position to increase the spacing of the cover from the rods so as to permit entrance to and egress from the fixture of such a boule. A lever projects from the cover and is biased so as to maintain the cover in its first position. Means are also provided to engage the lever to override the biased cover to lift the cover into the second position to facilitate entry and removal of the crystal boule.
