Abstract: A gripper that is designed to incorporate the functions of gripping, supporting and pressure tongs into one device. The gripper has two opposing finger sections with interlocking fingers that incline and taper to form a wedge. The interlocking fingers are vertically off-set so that the opposing finger sections may close together allowing the inclined, tapered tips of the fingers to extend beyond the plane defined by the opposing finger section's engagement surface. The range of motion defined by the interlocking relationship of the finger sections allows the gripper to grab, lift and support objects of varying size and shape. The gripper has one stationary and one moveable finger section. Power is provided to the moveable finger section by an actuating device enabling the gripper to close around an object to be lifted. A lifting bail is attached to the gripper and is supported by a crane that provides vertical lift.

Abstract: A system for changing the gloves of a glove box. The system requires the use of a new glove and a glove change ring to form a temporary secondary barrier to the exchange of atmospheres between the inner glove box and the room in which the glove box is operated. The system describes specific means for disengaging a used glove from the glove box port. The means for disengaging the used glove include use of a glove change hook and use of a glove with an attached tab for use in removal. A method for changing the gloves of a glove box is also described.
