Abstract: An adjustable gripping apparatus having two pairs of grippers. Each of the grippers of the first pair is slidably mounted for sliding movement along a laterally extending guide means. Each of the grippers of the second pair is mounted on an associated one of a pair of oppositely spaced gripper positioning members. The gripper positioning members are each rotatably supported to rotate about a pivot axis extending perpendicular to the lateral direction of the guide means. A pair of articulating linkage assemblies are provided, each of which is pin connected at one end to one of the first pair of grippers and fixedly connected at the other end to an associated one of the gripper positioning members. The joint of each articulating linkage assembly is offset from the pivot axis of its associated gripper positioning member so that rotation of the gripper positioning member causes sliding movement of the associated gripper of the first pair to change the gripping position thereof.
