  • Method and means for limiting the extent of release travel of piston-operated grippers
    Patent number: 4741568
    Abstract: A piston-operated robotic gripper system has gripper means including a piston mounted within a cylinder for movement between a first position and a second position, with the piston operatively linked to move grasping means between a first retracted position and a second extended position corresponding to the first and second piston positions, respectively. Conduit means are connected to first and second sides of the piston to introduce pressurized fluid into the cylinder on the first side of the piston to cause the piston and grasping means to move to their first positions and to introduce pressurized fluid into the cylinder on the second side of the piston while exhausting the fluid from the cylinder on the first side of the piston to cause the piston and grasping means to move to their second positions.
