TRAP
Two serrated jaws close around the animal's body instead of the leg.

A bow-spring is depressed to open a pair of arcuate serrated jaws pivoted on a central post, and a latch holds the baited trigger in place. The animal stands on the base plate and disturbs the bait, which is positioned directly forward of the jaws' pivot point. The latch releases, the spring drives the jaws together, and the jaws clasp the animal's body. This prevents the animal from ruining its fur or severing its leg to escape.
“Now in case an animal approaches the trap and attempts to take the bait, he will of course be inclined to come upon the base plate and stand in a position so that when the trap is swung, the jaws J will close about the body of the animal. It is important that the bait 24 be positioned as shown in order to accomplish these results.”— Clay Theriot, from the specification
And the world did not beat a path to his door.
