Patent ID: 7360444

Claim:
A device adapted to interact with a generally cylindrical mold for a gyratory compactor apparatus defining an axis, the mold having an outer diameter and defining an axis, the mold also having opposed first and second ends and a radially extending flange having an outer diameter, and the mold being adapted to have a sample disposed therein, said device comprising: a movable mounting plate configured to be movable between a first position and a second position along the apparatus axis; a pair of pivoting members pivotably mounted to the movable mounting plate along parallel pivot axes; and a support rail mounted to each pivoting member, the support rails being laterally separated by less than the outer diameter of the flange with the movable mounting plate in the first position such that the support rails are capable of supporting the mold by the flange, the pivoting members pivoting between the first and second positions such that, with the movable mounting plate in the second position, the support rails are separated by more than the outer diameter of the flange and are thereby incapable of supporting the mold by the flange.
