Abstract

143,770. Lemons, G. G. Sept. 1, 1919. Grapnels. - Fig. 5 shows the lower or grapnel end of a ram which is dropped upon a sunken vessel to penetrate it and thus enable it to be hauled up. The arms 27 are kept folded in umbrella fashion by the engagement of the runner 24 with a trigger 30, which is liberated after penetration by a cartridge 32 fired by electricity, or by pneumatic or other means. In case gravity is not sufficient to effect penetration, the ram may be rotated so that its pointed end 21 drills a hole in the vessel, Additional catches 41, Fig. 6, may be placed above the main arms 27.
