This video addresses allegations that the 'Super Safety' infringes on existing US patents. The creator provides links to three specific patents (US12038247B2, US7398723B1, US10514223B1) for viewers to research themselves. The video also links to the 'Super Safety release video' for additional context on the product. The focus is on the legal and patent aspects surrounding the Super Safety device, rather than its direct firearm application or performance.
This video analyzes the Savage rotating-barrel system, a design from Elbert Searle's 1905 patent. The patent claimed a positively locked breech created by the barrel rotating before the slide could move rearward. However, the analysis reveals the breech opens before the bullet leaves the barrel, as breech pressure overcomes the rotational force. Despite not achieving a positively locked breech, the system does provide some delay and allows for a lighter moving mass compared to the Browning model 1900. The video concludes the Savage system is safe and reliable, even if its primary claim isn't fully realized.
This video delves into a fascinating patent dispute between firearm design titans John Browning and Hiram Maxim. The core of the conflict revolves around Browning's Model 1895 machine gun, specifically its rotary-lever gas operation. Maxim claimed patent infringement, arguing his own patents broadly covered gas piston operation, albeit in a linear format. Browning and Colt countered by asserting the swinging lever mechanism was distinct and even demonstrated a working prototype that bypassed gas operation entirely using a muzzle cap system. While the legal battle's ultimate outcome was rendered moot by the 6mm Lee Navy's performance issues, this historical patent fight and the experimental firearm it produced are the focus.
This video focuses on the Slocum Rimfire Revolver, a notable firearm from the Brooklyn Arms Company. Designed by Frank Slocum, it offered a practical solution to overcome Rollin White's patent on bored-through cylinders. A key feature highlighted is its compatibility with standard .32 rimfire cartridges, achieved through an innovative chamber sleeve design that uses removable chamber pieces. This made it more accessible than other designs that required proprietary ammunition.
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.
