  • Animal trap
    Patent number: 4622774
    Abstract: An improved animal trap adapted to be less injurious to a trapped animal because of a center mounted swiveling chain. The trap also has a flat base made possible by novel way of fastening the trigger mechanism to the base and uses a novel self-setting trigger system. Furthermore, because of unique jaw levers, the initial force tending to close the trap is substantially greater than that of former traps of similar size and conformation.
