This video from Forgotten Weapons explores the fascinating guns involved in the Winchester-Bannerman patent infringement lawsuit over pump-action firearms. It highlights a prototype Magot pump-action rifle and a Winchester-built Krutzsch patent pump-action rifle, presented at the Cody Firearms Museum. The lawsuit stemmed from Bannerman's ownership of the first US patent on pump-action shotguns, acquired from Sylvester Roper. Winchester defended itself by proving the patent's invalidity through prior art, including these obscure European designs, ultimately winning the case and leading to the development of their successful Model 1897 pump shotgun. The video emphasizes the impracticality of the Magot and Krutzsch designs, yet acknowledges their significance in patent law.
This video delves into the history and design of the Roper Repeating Rifle and Shotgun, a fascinating early example of cartridge firearms. It highlights the collaboration between Sylvester Roper, the original designer, and Christopher Spencer, who played a crucial role in its production after the Civil War. The description details the rotary magazine, reusable steel cartridges, high initial price point, and the eventual sale of the company. It also touches upon Spencer's subsequent ventures, including the invention of the automatic screw machine.
This video delves into the historical Roper Revolving Shotgun, an early cartridge-firing repeating shotgun from the 19th century. The description highlights its unique open-bolt mechanism, detailing how cocking the hammer chambers a round and firing ignites it. It also explains the extraction process, which leaves spent casings in the magazine carousel, requiring manual unloading. The video notes Sylvester Roper's contributions beyond firearms, including work on motorcycles and automobiles, and his patent sharing for the first pump-action shotgun. The addition of dummy cartridges for demonstration is also mentioned.
This video delves into the history and evolution of Winchester pump-action shotguns, focusing on the influential Model 1897. It details how John Browning's design, initially released as the 1893 model, was adapted to handle smokeless powder and overcome patent disputes with the Spencer shotgun. The description highlights the 1893's limitations with early smokeless powder and the subsequent product recall and replacement with the more robust 1897 model, contributing to the scarcity of the 1893 variant today. The video also touches upon the patent landscape involving Christopher Spencer and Sylvester Roper.
This video examines the Roper Repeating Shotgun, a design patented by Sylvester Roper in 1866. The shotgun features a 4-round magazine for 12-gauge shells and an unusual open-bolt firing mechanism. Although the specific example shown is missing internal magazine components and has a damaged bolt, it represents a significant historical firearm. The description also notes Roper's broader inventive contributions, including his work with Christopher Spencer on pump-action shotguns and his pioneering efforts in motorcycle design.
