  • Patent number: 4136415
    Abstract: An underwater release mechanism for a shackle including a shaft releasably journaled in a casing and held in position by a frangible link to be spring biased to release a shackle hook upon remote actuation causing the link to fracture whereby the shackle is released and the release mechanism floats to the surface. The frangible link externally connected to the casing members to facilitate replacement of the frangible link and reuse of the release mechanism. A rope canister can be attached to the casing with one end of the rope tied to the shackle whereby after release the canister end of the rope will be tied to the float to mark the spot of the shackle. Also a force multiplier can be added to the release mechanism via a second retaining bracket and a second shackle hook to increase the casing load by a ratio of at least 5:1 as for example a release mechanism capable of a 400 pound load would have a 2000 pound load capacity.
