Patent
·
OSTI ID:6423076
This patent describes an apparatus for orienting first and second members in a preselected rotary alignment and for maintaining their rotary alignment during orientation. The apparatus comprises: a first cylindrical element having an outside wall and first and second ends, each of the ends having an outside edge, the first cylindrical element having portions defining notches disposed in a spaced-apart pattern at the outside edge of the first end, the first cylindrical element having an external threaded portion disposed on the outside wall and adjacent to notches, the first cylindrical element being connected at its second end to the first member; a second cylindrical element having an outside wall and first and second ends, each of the ends having an outside edge, the first end of the second cylindrical element having substantially the same outside diameter as the first end of the first cylindrical element; a rotation prevention element for placement within the cavity, the rotation prevention element being sufficiently large relative to the cavity to prevent rotation of the overlapping first cylindrical element notch past the overlapping second cylindrical element notch; and a collar slidably disposed about the second cylindrical element, having an internal threaded portion for interfittably engaging portion of first cylindrical element to connect second and first cylindrical elements.
