Casimir Lefaucheux’s Patent for Improvements to Pauly’s Firearm System, No. 3590, 1828

Description

This document represents Casimir Lefaucheux's third addition to the patent improvements of the firearm system initially invented by Samuel Johannes Pauly, documented under dossier number 1BA1814(3) in 1828. Lefaucheux, an arquebusier in Paris, sought to enhance the Pauly system, which was a significant development in breech-loading firearms.

In his petition, Lefaucheux emphasizes the simplification of Pauly's complex system, particularly focusing on the removal of multiple parts of the firearm's "bascule" or movable breech, which were deemed unnecessary for the weapon's operation. This refinement aimed at improving the precision and reliability of the breech-loading mechanism.

The patent reflects Lefaucheux's contributions to streamlining Pauly's design to create a more efficient and user-friendly firearm. His improvements are described in a detailed memorandum, which includes the removal of various components of the system, and marked in red on the accompanying illustrations to highlight the changes.

Lefaucheux's approach demonstrates an early example of optimizing existing technology for better performance, a principle that continues to drive innovation today. The patent process, as outlined in the document, illustrates the rigorous requirements for inventors in the 19th century to establish their claims and secure the exclusive rights to their improvements. This patent addition is a testament to Lefaucheux's ingenuity and the progressive evolution of firearm technology during that era.
