Though used before this, (as seen in surviving pinfire shotshells that lists the names of early gun makers he signed contracts with in 1833 and 1834,) [1] [5] in 1835 [2] he was granted an addition to the 1832 patent for a new type of cartridge in which the cartridge's priming compound is ignited by striking a small pin which protrudes radially ...
Casimir Lefaucheux obtained his first patent in 1827. In 1832, he completed a drop-barrel sporting gun with paper cartridges. [1] Lefaucheux is credited with the development of one of the first efficient self-contained cartridge systems. This 1835 invention, featuring a pinfire mechanism, followed the pioneering work of Jean Samuel Pauly in
The 12mm Lefaucheux is a metallic center-fire cartridge. It was originally created as a rimless pinfire cartridge using black powder employed by the French navy on the Lefaucheux M1858 revolver. Later it was adapted to a center-fire cartridge by the French Army in 1873 for use on the MAS 1873 revolver.
The Lefaucheux M1858 was a French military revolver developed for the navy, chambered for the 12 mm pinfire cartridge, and based on a design by Casimir Lefaucheux and his son, Eugene (also a gun designer). The 1854 model was the first metallic-cartridge revolver adopted by a national government; the 1858 was the first variant fielded. [4]
A pinfire firearm cartridge is an obsolete type of brass cartridge in which the priming compound is ignited by striking a small pin which protrudes radially from just above the base of the cartridge. Invented by Casimir Lefaucheux in 1828, but not patented until 1835, it was one of the earliest practical designs of a metallic cartridge.
The M1854 model was a single-action, pinfire revolver holding six rounds. [1] It was a French military revolver chambered for the 12 mm pinfire cartridge, based on a design by Casimir Lefaucheux (Eugene's father, who was also a gun designer). The M1854 revolver spawned numerous variants, some of which were produced under license in other countries.
This made the cartridge base much stronger, as early rimfire cartridges tended to split at the base, causing extraction malfunction. It was also more economical, as only 1/8th of the expensive fulminate was required. Ethan Allen then invented manufacturing equipment for metallic cartridges that far exceeded the competition in quality and ...
One of the earliest efficient modern cartridge cases was the pinfire cartridge, developed by French gunsmith Casimir Lefaucheux in 1836. [35] It consisted of a thin weak shell made of brass and paper that expanded from the force of the explosion. This fit perfectly in the barrel and thus formed an efficient gas check.
