Frequently Asked Questions

What is the 1882 rat trap patent?

The 1882 US patent (No. 269,766) by James Alexander Williams proposed an 'Animal Trap' that utilized a firearm, such as a revolver, mounted on a frame. When a pest triggered the trap mechanism, it would pull the firearm's trigger, firing a projectile at the animal.

How does the 1882 rat trap mechanism work?

The replica uses a string to connect the trigger of a standard rat trap to the trigger of a firearm, like an 1851 Navy revolver. When the rat trap is sprung by an animal, the tension from the string pulls the firearm's trigger, causing it to discharge.

What firearms were tested with the rat trap replica?

The replica was initially tested with an 1851 Navy cap-and-ball .44 caliber revolver. Subsequent tests involved a Smith & Wesson Model 500 chambered in .500 S&W Magnum and a Serbu Super Shorty 12-gauge shotgun.

What are the potential dangers of the firearm rat trap?

The primary dangers include the unpredictable recoil of the firearm, especially if unrestrained, leading to potential movement or damage. Additionally, the discharge of a firearm, particularly with black powder, creates significant muzzle flash and noise, posing risks in unintended directions.
