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
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 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]
To manufacture cases for cartridges, a sheet of brass is punched into disks. These disks go through a series of drawing dies. The disks are annealed and washed before moving to the next series of dies. The brass needs to be annealed to remove the work-hardening in the material and make the brass malleable again ready for the next series of dies ...
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.
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.
I checked the 10 or so original pinfire drawing that I have from various companies, and they list an angle of between 5º and 8.5º --AaronN322 00:54, 31 January 2014 (UTC) Review the available images, the hammer of a pinfire weapon is L-shaped, resulting in an impact directed more or less straight down (give or take a few degrees).
