  • Patent number: 8429848
    Abstract: A mole trap has a tough plastic base with downwardly extending fixed blades. Movable plastic blades are pivotably connected to the base and urged into a sprung condition by springs. A two-segment lever extends between the base and a catch which is pivotably mounted to the base. A trigger extends through a central opening in the catch and has a post which protrudes beneath the catch where it can be actuated by the targeted mole. Operation of the trigger post causes the lever to release from its engagement with the catch so that the movable blades close on and strike the mole positioned beneath the trap. The trigger has a release tab extending from the lever, allowing convenient release from the set position, and an upwardly protruding set arm allowing trigger depression from a point exterior to the handle into its desired set configuration.

  • Patent number: 7367154
    Abstract: The present invention provides a force applying lever assembly for use with a foothold type trap. The force applying lever assembly has at least one force applying lever that is coupled to the biasing device or spring of the trap. The at least one force applying lever is also pivotally coupled to the base of the trap, allowing it to pivot with respect to the base. The trap's anchor, which is usually coupled to the base of the trap, is instead coupled to the end of the force applying lever opposite the base. When the ensnared animal pulls against the anchored trap, the pulling causes the force applying lever to pivot with respect to the base so as to increase the biasing force applied by the biasing device on the jaws. This additional biasing force on the jaws tightens the grip on the ensnared animal, which prevents it from escaping and discourages it from struggling.

The choke ensures that upon passage of a mole through a tunnel, the trap will activate thereby causing the jaws to come together on the mole. The choke may be removably or permanently secured to the free end of a trip-pan which integrally forms a part of the mole trap.

  • Patent number: 6508031
    Abstract: A rodent trap particularly adapted for rats has a plastic base to which a plastic upper jaw is pivotably mounted by a steel pin. A spring is engaged between the base and the upper jaw and urges the jaw to close upon the base. A trigger is pivotably mounted by the pin to ears which project upwardly from the base. A catch mechanism operates to restrain the upper jaw in a set position until the trigger is actuated. A plastic bait container has radially protruding flanges which permit it to be extended through a hole in the base beneath the trigger and secured to the base such that the bait within the container is accessible through another hole in the trigger. In one embodiment, the bait container is generally cylindrical and is twisted into place. The bait container is readily removed for replenishment.

  • Patent number: 6397517
    Abstract: An injection molded plastic body has a lid joined by a living hinge. A rodent passageway extends within the body between two aligned holes. The hinge is perpendicular to the passageway, allowing the lid to be opened when the body is fixed adjacent a building wall. The interior of the body is divided by a raised wall which is broken into two segments by an opening to a blind passageway extending perpendicular to the passageway. Two rodent feeding areas are positioned adjacent the blind passageway. Bait blocks are positioned within each feeding area on protrusions which are received within axially extending central holes. The blocks are clamped between underlying rings and cooperating structure depending downwardly from the lid. Instead of bait, a mechanical trap maybe positioned on two of three protrusions aligned along the blind passageway. The mechanical trap inter-fits with the protrusions to positively position the mechanical trap.

  • Patent number: 5907922
    Abstract: The trap comprises a frame and a pair of jaws pivotally mounted to the frame. Each jaw may be moved between an opened position and a closed position where the jaws are against the leg of the animal to be caught. The jaws are devoid of teeth or acute portions in order not to wound the caught animal. A lace, provided with a one-way loop and having one end anchored to a tree or a root, is positioned underneath the jaws in order to tighten itself around the leg of the animal. When using the trap, the animal that is caught will try to escape, this will have the effect of moving the trap. However, because the lace is anchored, it will tighten itself on the leg of the animal in order to prevent its escape. The animal may move the trap further and extract his leg from the jaws without injury, but it is still caught by the lace. Thus, this device allows one to catch animals without severely wounding them, as it is the case with usual jaws traps with teeth.

  • Patent number: 5307587
    Abstract: An animal trap particularly suited for trapping moles. The trap has a frame formed by two interfitting bails or U-shaped members pivotally joined at their legs so as to form a pair of scissor-like clamps. The distal end of each leg of the U-shaped members has one-half of an animal gripping jaw which cooperates with an opposing one-half of a jaw on the distal end on the adjacent leg of the associated U-shaped member. A shaft extends between the legs of the U-shaped members. The opposite ends of the shaft are welded to the legs of one U-shaped member. The legs of the other U-shaped member are pivoted on the shaft. A pair of coil springs are mounted on the shaft the outer ends of which drivingly engage the legs which are pivoted on the shaft. The inner end of each spring drivingly engages a trigger lever which projects from the shaft. The driving torque exerted by the springs urges the jaw halves into their closed animal gripping condition.
