John T. Kewish
John T. Kewish was born in 1868 in Smithtown, NY and was the principal creator of the primer actuated blowback machine gun in 1918 which is covered by U.S. patent no. 1,472,126. John C. Garand was assigned 25% as co-inventor. Kewish was also a contributor to several later automatic firearm developments. He died March 1, 1945 in New York, NY.

US001472126
The United States of America (U.S.A. or USA), commonly known as the United States (U.S. or US) or America, is a country primarily located in North America. It consists of 50 states, a federal district, five major unincorporated territories, nine Minor Outlying Islands, and 326 Indian reservations. The United States is also in free association with three Pacific Island sovereign states: the Federated States of Micronesia, the Marshall Islands, and the Republic of Palau. It is the world's third-largest country by both land and total area. It shares land borders with Canada to its north and with Mexico to its south and has maritime borders with the Bahamas, Cuba, Russia, and other nations. With a population of over 333 million, it is the most populous country in the Americas and the third most populous in the world. The national capital of the United States is Washington, D.C. and its most populous city and principal financial center is New York City. Paleo-America ...

Primer (firearms)
In firearms and artillery, the primer () is the chemical and/or device responsible for initiating the propellant combustion that will push the projectiles out of the gun barrel. In early black powder guns such as muzzleloaders, the primer was essentially the same chemical as the main propellant (albeit usually in a finer-powdered form), but poured into an external flash pan, where it could be ignited by an ignition source such as a slow match or a flintlock though some muzzleloaders have primers like cap gun caps. This external powder was connected through a small opening at the rear of the gun barrel that led to the main charge within the barrel. As gunpowder will not burn when wet, this made it difficult (or even impossible) to fire these types of weapons in rainy or humid conditions. Modern primers, by contrast, are more specialized and distinct from the main propellant they are designed to ignite. They are of two types, those using shock-sensitive chemicals, and those reli ...

Machine Gun
A machine gun is a fully automatic, rifled autoloading firearm designed for sustained direct fire with rifle cartridges. Other automatic firearms such as automatic shotguns and automatic rifles (including assault rifles and battle rifles) are typically designed more for firing short bursts rather than continuous firepower, and are not considered true machine guns. As a class of military kinetic projectile weapon, machine guns are designed to be mainly used as infantry support weapons and generally used when attached to a bipod or tripod, a fixed mount or a heavy weapons platform for stability against recoils. Many machine guns also use belt feeding and open bolt operation, features not normally found on other infantry firearms. Machine guns can be further categorized as light machine guns, medium machine guns, heavy machine guns, general purpose machine guns and squad automatic weapons. Similar automatic firearms of caliber or more are classified as aut ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Garand
Jean Cantius Garand (; January 1, 1888 – February 16, 1974), also known as John C. Garand, was a Québec-born American designer of firearms who created the M1 Garand, a semi-automatic rifle that was widely used by the U.S. Army and U.S. Marine Corps during both World War II and the Korean War. Early life Garand was one of twelve children (six boys and six girls) born on a farm near St. Rémi, Quebec. His father moved to Jewett City, Connecticut, with the children when their mother died in 1899. All of the boys had the first name St. Jean le Baptiste, but only he went by the first name Jean. The other boys went by their middle names. Several of his brothers were also inventors. The children were employed in a textile mill where Jean learned to speak English while sweeping floors. Jean became interested in guns and learned to shoot after working at a shooting gallery. Jean learned machinist skills while working at the textile mill, and was hired by Browne and Sharp ...

Blowback (firearms)
Blowback is a system of operation for self-loading firearms that obtains energy from the motion of the cartridge case as it is pushed to the rear by expanding gas created by the ignition of the propellant charge. Several blowback systems exist within this broad principle of operation, each distinguished by the methods used to control bolt movement. In most actions that use blowback operation, the breech is not locked mechanically at the time of firing: the inertia of the bolt and recoil , relative to the weight of the bullet, delay opening of the breech until the bullet has left the barrel. A few locked breech designs use a form of blowback (example: primer actuation) to perform the unlocking function. The blowback principle may be considered a simplified form of gas operation, since the cartridge case behaves like a piston driven by the powder gases. Other operating principles for self-loading firearms include delayed blowback, blow forward, gas operation, and recoil o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
