Abstract
A gripper which automatically grips the screw cap on a jar or the like when it is moved thereinto in order to facilitate removal of the cap. It includes a motor-operated clamp which is automatically actuated by movement of the capped jar thereinto to grip the cap and suspend the jar so that, thereafter, both hands of the user are free to grip the jar and turn it relative to the clamped cap. After the jar is separated from the clamped cap, the motor may be actuated to release the cap from the clamp.
