Abstract : A release mechanism is provided for a structural member, such as a cylindrical object recovery device, wherein the structural member has top and bottom sides. The release mechanism includes a block which is attachable to the structural member so as to extend thereabove. A piston is mounted in the block and is moveable vertically between up and down positions. At least one rod is connected to the piston and extends vertically downwardly beyond the bottom side of the structural member so as to be capable of moving the piston to the upward position when forcinly engaged by the object. A U-shaped holder is fitted over the block with each leg of the holder having a recess. A pair of pistons is laterally mounted in the U-shaped block in an opposing relationship, and each piston is moveable between inward and outward positions. Each lateral piston is engageable with the holder within the holder recess in the outward position so as to retain the U-shaped holder to the block, and each lateral piston clears the respective holder recess in the inward position so as to release the U-shaped holder from the block.
