ABSTRACT:
A recovery tool is located and affixed to a recovery object by a mechanical anipulator extending from an undersea vehicle. The manipulator squeezes a pair of spring biased actuators on the tool and interconnected linkage is displaced. The displaced linkage longitudinally slides an actuator tube on a lift rod and rotates a crossbar from its orthogonal disposition on the lift rod to an axially aligned position. The manipulator inserts the lift rod through a hole or ring provided in the recovery object and relaxes its squeezing force. The spring biased actuators spread apart and the interconnected linkage withdraws the actuator tube. A small spring carried inside the lift rod rotates the cross bar to its orthogonal position. When so disposed the crossbar cannot be withdrawn through the hole on the object. Thusly, a hoisting cable coupled to the recovery tool is joined to the object allowing its recovery to a surface or other undersea craft.
