Abstract:
1. A device for separating ceramic elements from a metal base member, said device comprising: a rigid body shaped with an interior surface being threaded, said body complementarily to an interior surface of an opening of the base member and receivable therein; opposed wedge members mounted in a wall of said body; and a bolt having a generally conically shaped end for threaded engagement with the interior surface of said body; wherein each of said wedge members is engageable with one of the ceramic elements, such that upon insertion of said body in the base member and threaded movement of said bolt inward of said body, the conically-shaped end of said bolt engages said wedge members to urge said wedge members outward through the wall of said body to engage opposed ceramic elements to urge the ceramic elements apart from the base member, thereby separating the ceramic elements from the base member.
