I don't have to worry about getting kidnapped. They would bring me back in less than an hour!
Thomas Jackson RodmanBorn 30 Jul 1815; died 7 Jun 1871 at age 55.U.S. military inventor of perforated-cake gunpowder. Its hexagonal grains, perforated with several longitudinal holes, increased the burning surface of each grain. By burning evenly, it provided controlled rather than sudden pressure that was maintained as the projectile traveled forward, thus giving increased muzzle velocity. He also invented a system of casting cannon around a hollow core cooled from inside, resulting in a stronger barrel as concentric layers of metal cooled and shrank. His work led to casting of some of the largest cannon ever built: 20-inch muzzleloaders that fired 1,080-pound solid shot.[Image: Rodman Cannon at Fort McHenry.] |
