The first automatic machine gun was the [[Maxim gun]], invented by [[Hiram Maxim]]. The Maxim gun was the first weapon to utilize a gas blowback system; the excess gas of the previously ejected round pushed the bolt back far enough to chamber a new round. The Maxim gun also saw the first use of a coolant system, in the form of a water jacket; the barrel of the gun was surrounded by a "jacket", or sheath filled with water. In addition, the ammunition was fed into the block mechanism by means of a continuous metal belt, several of these belts could be linked together to enable a sustained rate of continuous fire. These improvements greatly increased the sustained fire time of the gun. Maxim was an American inventor who lost some patent battles with [[Thomas Edison]] on the [[light bulb]] and other inventions, and was persuaded to move to [[Europe]] and make improvements to weaponry there. | The first automatic machine gun was the [[Maxim gun]], invented by [[Hiram Maxim]].
