Gardner gun

The Gardner gun was an early type of mechanical machine gun. It had one or two barrels, was fed from a vertical magazine or hopper and was operated by a crank. When the crank was turned, a feed arm positioned a cartridge in the breech, the bolt closed and the weapon fired. Turning the crank further opened the breechblock and extracted the spent case.

Development

The Gardner machine gun was invented in 1874 by William Gardner of Toledo, Ohio formerly a captain in the Union army during the American Civil War. After producing a prototype he went to the Pratt and Whitney company, who after a year of development produced a military version of the weapon.

A demonstration to officers at the United States Navy yard in 1875 was successful, however they recommended that Pratt and Whitney continue with development of the system, incorporating improvements to the feed system, which were designed by E.G. Parkhurst, an engineer at Pratt and Whitney. The army attended the tests, but showed no interest in the weapon.

Machine gun

A machine gun is a fully automatic mounted or portable firearm, designed to fire bullets in quick succession from an ammunition belt or magazine, typically at a rate of 300 to 1800 rounds per minute. Fully automatic weapons are generally categorized as submachine guns, assault rifles, battle rifles, automatic shotguns, machine guns, or autocannons.

As a class of military firearms, true machine guns are fully automatic weapons designed to be used as support weapons and generally used when attached to a mount or fired from the ground on a bipod or tripod. Light machine guns are small enough to be fired hand-held, but are more effective when fired from a prone position. The difference between machine guns and other categories of weapons is based on caliber, with autocannons using calibers larger than 20 mm, and whether the gun fires conventional bullets, shotgun cartridges, or explosive rounds. Fully automatic guns firing shotgun cartridges are usually called automatic shotguns, and those firing large-caliber explosive rounds are generally considered either autocannons or automatic grenade launchers ("grenade machine guns"). Submachine guns are hand-held automatic weapons for personal defense or short-range combat firing pistol-caliber rounds. In contrast to submachine guns and autocannons, machine guns (like rifles) tend to have a very high ratio of barrel length to caliber (a long barrel for a small caliber); indeed, a true machine gun is essentially a fully automatic rifle, and often the primary criterion for a machine gun as opposed to a battle rifle is the presence of a quick-change barrel, heavyweight barrel, or other cooling system. Battle rifles and assault rifles may be capable of fully automatic fire, but are not designed for sustained fire.

Machine

A machine is a tool containing one or more parts that uses energy to perform an intended action. Machines are usually powered by mechanical, chemical, thermal, or electrical means, and are often motorized. Historically, a power tool also required moving parts to classify as a machine. However, the advent of electronics has led to the development of power tools without moving parts that are considered machines.

A simple machine is a device that simply transforms the direction or magnitude of a force, but a large number of more complex machines exist. Examples include vehicles, electronic systems, molecular machines, computers, television, and radio.

Etymology

The word machine derives from the Latin word machina, which in turn derives from the Greek (Doric μαχανά makhana, Ionic μηχανή mekhane "contrivance, machine, engine", a derivation from μῆχος mekhos "means, expedient, remedy").

A wider meaning of "fabric, structure" is found in classical Latin, but not in Greek usage.

This meaning is found in late medieval French, and is adopted from the French into English in the mid-16th century.
