Machine gun

In 1856, Charles E. Barnes patents a crank operated machine gun. It was ahead of its time, but similar to other machine guns invented later. Although it was invented before the outbreak of the war, there is no evidence that it was used by either side. (Dr. Richard J. Gatling, a North Carolina farm boy, patented his renouned six-barrel machine gun on November 4, 1862.)
