Abstract
455,824. Raising sunken ships. LEROUX, R. P., 116, Rue des Chalatres, Nantes, Loire Inferieure, France. Oct. 22, 1935, No. 29132. Convention date, March 7. [Class 68 (ii)] [See also Group XXX] , A means for raising a sunken submarine comprises a series of pontoons, Fig. 6, which are towed to the spot and attached to loops 1 on the ship by hand-operated tongs-like hooks 13, Fig. 4. These hooks are at the ends of cables 12 dropped from a salvage vessel, and are attached to the loops 1 by a diver. Alternatively the cables 12 may be unwound from the sunken vessel by released buoys. The cables 12 being in position, the pontoons are guided down them until larger hooks 11 on them engage with the loops 1. Each pontoon consists of an inner and outer casing 5, 4, forming a ballast tank 6 containing compressed-air bottles 29 by means of which water is expelled when desired from the tank 6. The casing 5 encloses a driving- apparatus 7 for a winch 9 for winding up the cable 12. The device, Fig. 4, for causing the hook 11 to engage with the loop I comprises compression springs 19 or equivalent devices in cylinders 16. The device passes down the cable 12 until the collar 26 meets the cone 15, when the distortion of the wires 23 &c. causes the latches 22 to release the pistons 17, and enables the springs 16 to close the hooks 11 over the loops 1.
