On August 30, 1881, W.S. Campbell patented the self-setting animal trap, which is patent number 246,369. This innovation made it easier for people to catch animals without having to manually set the trap each time. The design was a significant improvement in trapping technology and helped improve the efficiency and practicality of trapping animals for various purposes, such as pest control or fur trapping.
It was a key development in the evolution of animal traps, paving the way for modern versions of self-setting traps used today.
