Abstract
A simulated suspended mine retrieval system is described. It snares a simted suspended mine at sea that is comprised of an anchor, a buoy and a tether connecting the anchor and buoy. The retrieval system has a cable connected to a loop for snaring the simulated suspended mine. In operation the retrieval system is towed from a vessel and the loop passes over the mine and strikes the tether. When this happens the loop has a shackling arrangement that snares the tether and is of such a size that it cannot slip over the mine. This enables the simulated suspended mine to be hoisted upon the towing vessel.
Claims3
A simulated suspended mine retrieval system comprising:
- a tow cable;
- and
- a loop attached to said tow cable, said loop includes a spring loaded locking shackle comprised of a substantially U-shaped bar having a locking arm with a torsion spring, one end of said locking arm being affixed to one leg of said U-shaped bar and the other end being held in abutment with the other leg of said U-shaped bar for inhibiting the other end of said locking arm from moving toward the end of said other leg of said U-shaped bar and for enabling said locking arm under a torque greater and opposite to that of the torsion spring to move away from the other leg of the U-shaped bar toward the center of the U-shaped bar.
