IMPROVEMENTS IN SUBMARINE SPEARGUNS, characterized by the fact that, essentially, they consist of an airtight compression chamber inside which there are housed two harpoon tubes, a pair of sealed tanks in which two chemical substances are lodged respectively, which by means of external stopcocks can be mixed in the lower compression chamber, in which they react forming a gas that presses on the culottes of the harpoons that are held inside their tubes by externally operating triggers; in such a way that when firing them in succession or simultaneously, they allow the projection of the harpoons to the outside; closing automatically at the same moment of the shot some valves that were kept open at the ends of the tubes spear harpoons when they are not already retained by the end of the harpoon itself and by virtue of springs that push them down to hermetically close the open end of the respective tubes.
