In France, at the end of the XVIII century, there are 3 private manufactures which manufacture rifles of the army: *
MAUBEUGES, CHARLEVILLE and SAINT-ETIENNE.
The bursting of these centers of manufacture and their private management don’t facilitate the military action of the persons in charge to make evolve the methods. The manufacture of a traditional rifle is worked with the forging mill and the file starting from steel and iron blades which undergo many heats, to forge a barrel asks 63 of its heats (Weldings) on a pin by several hammerings on heated iron has white. Then the barrel is drilled by the passage of several drills. The other principal part of rifle is the lock, its design asks for also precision of manufacture. New techniques of design were developed by DESCHAMPS since 1723, it invented this technology to limit the work of completion to the file on this principal part; its concept is the use of parts forged by hot stamping, the use of gauge of checking at each time of manufacture in order to obtain identical dimensions for each produced part.
The use of these gauges and matrices of forging mills limit the rejects and increase the production and the quality of its parts.
The division of the labor in fifteen stations, is sixty twelve workmen, who manufactured six thousand seven hundred and twenty locks per annum. Their tools cost eight hundred and eight livres (French money) (tournaments). However a lock costing 3 livres, if the tools were renewed every year, that did not increase the production cost that by 4% - the true problem of this production was with the deceleration of the production and rejects.
