Abstract
This disclosure relates to an automatic firearms having a rotatable drum with helical grooves therein so arranged as to cause a follower guided by said grooves to reciprocate at a speed proportional to the rotational speed of the drum. The reciprocation of the follower causes the breech mechanism to reciprocate between loading and firing positions. The drum is driven by means independent of the propulsion energy of the projectiles fired, and therefore, may be operated at varying speeds by means such as an electric motor or even by hand.
