ABSTRACT:
A gripper device which includes a piston and cylinder assembly wherein the piston rod extends through one end of the cylinder, and which cylinder end is defined with a concave slot. Connected to the end of the piston rod is a gripper formed as a resilient member defining a pair of opposed finger portions and an interconnecting flexible web portion. The flexible web portion extends transversely of the outer concave slot. The arrangement is such that the actuation of the piston draws flexible web portion toward the concave slot surface of the cylinder causing the finger portions to flex between a gripping and non-gripping position; and whereby the gripper maintains a spring bias on the piston.
