Abstract : The patent relates to a recovery tool located and affixed to a recovery object by a mechanical manipulator 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 When so disposed the cross bar cannot be withdrawn through the hole on the object.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.
