Abstract
Abstract In combination with an actuating unit including a cylinder, a head and a reciprocal piston rod and a gripper head having a body terminating in a mount flange, a pivotal gripper assembly and a reciprocal rod end in the body connected to the gripper assembly. A quick disconnect device comprises an apertured protrusion block mounted upon the cylinder head including a pair of opposed undercut assembly slots. An apertured quick disconnect body of U-shape is secured upon the mount flange and upon its interior has a pair of opposed stop ledges. The disconnect body is projected into the assembly slots with the protrusion block nested upon the stop ledges. The actuating unit and gripper head are aligned with the piston rod axially connected to the rod end. A detent pin is removably projected through corresponding aligned transverse bores in the disconnect body and protrusion block.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
218 words
In combination with an actuating unit including a cylinder, a head on the cylinder and a reciprocal piston rod projecting outwardly of the head upon a longitudinal first axis; and a gripper head having a body terminating in an apertured mount flange, a pivotal gripper assembly mounted upon and projecting forwardly of the body and reciprocal operating means in the body connected to the gripper assembly, arranged upon a longitudinal second axis; a quick disconnect device comprising an apertured protrusion block receiving said piston rod mounted upon said head in a plane at right angles to said first axis, including a pair of opposed undercut assembly slots; an apertured quick disconnect body of U-shape secured upon said mount flange in a plane at right angles to said second axis; the interior of said quick disconnect body having a pair of opposed slotted portions defining a pair of stop ledges; the disconnect body being assembled over said head into said assembly slots with said protrusion block nested within the disconnect body upon its stop ledges; the first and second axes being in alignment with the piston rod axially connected to said gripper assembly operating means; and a single fastener detent pin removably projected through corresponding aligned transverse bores in said disconnect body and protrusion block and anchored in position.
