Improvement in Fire-Arms and in the Apparatus Used Therewith: United States Patent Office Application

"Improvement in Fire-Arms and in the Apparatus Used Therewith" by Samuel Colt is a technical publication detailing an innovative approach to firearm design, written during the early 19th century. This book, issued as part of Colt's patent application in 1839, focuses on improvements to rifles, guns, and pistols, aiming to enhance their operational efficiency and safety. The core topic revolves around the technical advancements made in the mechanics of firearms, which were significant during this period when gun technology was rapidly evolving. The content presents a detailed description of the design and functionality of Colt’s firearm innovations, elaborating on various components, such as the construction of the gun’s receiver, bolt mechanisms, percussion tubes, and an integrated loading apparatus. Colt outlines specific improvements aimed at eliminating lateral discharge risks, enhancing ignition methods, and improving loading efficiency with the introduction of a cap-primer and an ammunition flask. The book serves not only as a specification of Colt's inventive processes but also highlights the engineering principles that guided the development of the modern revolver, establishing Colt's legacy as a pioneer in firearm technology.
