580,924, for a recoil-operated locked-breech design which became the Colt Automatic Pistol of 1900.580,923, for a gas-operated automatic pistol that was never manufactured, but various elements of which appeared in later Browning pistols-particularly the disconnector.Were granted on 20 April 1897 and given successive numbers: There was, as yet, no established market for self-loading pistols in the U.S.Д«rowningвЂ™s first pistol patent was filed on 14 September 1895 and was followed just over a year later by three pistol patents filed on 31 October 1896. However, ColtвЂ™s was almost certainly acquiring the rights in order to protect sales of their revolvers. The right to manufacture four of his automatic pistol designs for distribution in the U.S. On 24 July 1896 Browning signed a contract giving ColtвЂ™s Producing one of BrowningвЂ™s machine gun designs, which marked the beginning of a long collaboration between John Browning and the ColtвЂ™s Company. In 1895 the ColtвЂ™s Patent Fire Arms Manufacturing Company began By 1894 Browning had completed his first prototype automatic pistol. Various types of self-loading weapons, both gas and recoil operated. He filed a patent on a gas-operated machine gun on 6 January 1890, and followed it with another dozen or so patents over the next decade on He filed his first firearm patent in 1879 at the age of 24.Д«rowning began experimenting with self-loading weapon designs late in 1889. John Moses Browning (1855-1926) grew up in his fatherвЂ™s gun shop and learned to repair guns before he learned to read and write. Self-loading pistols had limited sales and/or were intended primarily for military use.

The most significant successful designs (other than John BrowningвЂ™s) were those by Mannlicher, Bergmann, and Mauser. Number of people began serious work on designs for self-loading guns. But immediately after the invention of smokeless powder, a None of these efforts were ultimately viable because of the heavy residues left by black powder, which inhibits mechanical functioning very quickly. It burns much faster than black powder and produces comparatively little smoke, so it quickly became known as вЂњsmokelessвЂќ powder.ДЄ number of attempts to create a self-loading (automatic) weapon were made prior to the invention of smokeless powder, including a gas-operated revolver made by Orbea Hermanos of Eibar, Spain as early asДЎ863.

He called his invention poudre blanche, or white powder, to distinguish it from traditional black

But in 1884 the French chemist Paul Marie EugГЁne Vieille found a way to stabilize it. Guncotton is highly flammable and chemically unstable, so early efforts to utilize it as a gunpowder ingredient or explosive caused some seriousДisasters. Guncotton, or nitrocellulose, made by dipping cotton in a mixture of nitric and sulfuric acids, was patented in 1846 by a Swiss chemist by the name of Christian Friedrich SchГ¶nbein, based on earlier work byДЇrench chemists Henry Braconnot and ThГ©ophile-Jules Pelouze.
