Abstract
Inadvertent actuation of a rotating jaw trap is eliminated by limiting the rotation of spring-loaded jaw actuators in the trap set position. The position-limited actuators prevent opening of the jaws beyond the set position if one of the jaws is stepped upon by an animal which would otherwise release the trap-setting dog member from the trap trigger pan. With this elimination of slack in the set jaws, the trap is only sprung when the trigger pan is stepped upon. In the preferred embodiment, the limitation of rotation by the actuators is effected by upturned flange members from the trap frame or frame-holding bracket. The flange members may be apertured to receive pivot rods for the actuator members.
