    Abstract: An animal trap utilizes a generally X-shaped base to provide a balanced mounting of a pair of U-shaped jaws, a pair of torsion coil springs, and elements of a trigger mechanism. When the trap is set, the jaws are pivoted downwardly relative to the base and lie in a horizontal planesurrounding a trigger pan, whereby the set trap is of minimal height. A means of adjustment is provided to enable the force required to operate the trigger pan to be adjusted through a wide range to accommodate the trap for use with a wide variety of animals. Mounting rods extend through two spaced coiled portions of each of the torsion coil springs to couple the springs securely to the base. The springs have U-shaped leg portions which engage sides of the jaws and bias the jaws toward their closed position. The U-shaped leg portions wedge the jaws together as the jaws approach their closed position, and prevent the jaws from being moved apart by a trapped animal.

  • Patent number: 4479324
    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.

An elongate rod is pivotally connected to the bell crank at one end and engages one of the side members at a second end, when the jaws are horizontal, to maintain the trap in the open position. When an animal tugs on the bait, the rod disengages from the one side member and the trap closes to trap the head of the animal.

  • Patent number: 4133136
    Abstract: An animal trap having two similar frames each having jaw forming sides and ends extending between the sides to support the jaws. The ends have a central portion in which the frames are pivotally engaged through adjacent ends for rotation about a common axis between set and closed positions and outer portions on each side of the central portion of the jaws. At least one actuator capable of rapidly and forcefully effecting the rotation is present. The actuator has two arms spring biased at one end so that the other ends, which terminate in rings encircling adjacent ends of both frames on opposite sides of the axis would, if unobstructed, move apart to a distance substantially greater than the length of the frame ends. There are trigger means for releasably maintaining the trap in set position.
