Although the first Gatling gun was capable of firing continuously, it required a person to crank it; therefore it was not a true automatic weapon. The Maxim gun , invented and patented in 1883, was the first true fully automatic weapon, making use of the fired projectile's recoil force to reload the weapon.
The Maxim machine gun used the recoil power of the previously fired bullet to reload rather than being hand-powered, enabling a much higher rate of fire than was possible using earlier designs such as the Nordenfelt and Gatling weapons. Maxim also introduced the use of water cooling, via a water jacket around the barrel, to reduce overheating.
The Maxim gun is a recoil-operated machine gun invented in 1884 by Hiram Stevens Maxim.It was the first fully automatic machine gun in the world.
