ABSTRACT:
A recovery tool is designed to be actuated by the manipulator of an under vehicle. The undersea vehicle approaches an object to be recovered and its manipulator arm grips a pair of spring biased actuators. Linkage or lever arms extend from each of the actuators to off-center portions of a pair of pivotally mounted tongs. Squeezing the actuators together separates the tongs and they are placed about the object. When the pressures are released, the actuators force the tongs to grasp the object. A hoisting cable, coupled in a centrally in-lined position with respect to the tongs, hauls the object upward which causes the tongs to grip the object more securely.
