ABSTRACT:
Improved compound gripper device particularly useful with laboratory glassware and suitable for use with low or high gripping forces. When gripping forces are high, external gripper member is displaced into a resilient gripping pad which pad is of the type which provides the high-friction gripping force. On release of the gripping force, the external member is released and serves as a means to provide positive displacement of the object being held from the resilient, high-friction, gripping element.
