  • Patent number: 4884064
    Abstract: A method of and apparatus for detecting free-ranging pests, for example mice, without providing an attractant material. The presence of a pest is sensed by at least one of a plurality of sensors, a signal is emitted indicating the sensing of a pest by that sensor, and the fact that a signal has been emitted is indicated by an indicating means that is operatively coupled to the sensors.

  • Patent number: 4876821
    Abstract: This invention is a baited animal trap, positioned above a water reservoir and comprising a rotatable walkway held in position by a magnetic release device. Bait positioned beyond the walkway attracts an animal to walk thereon. The magnetic release device releases when an animal proceeds on the walkway causing the walkway to rotate and plunge the animal into the water reservoir. A reset device attached to the walkway causes the walkway to re-rotate to re-engage the magnetic release device and thus automatically resets the trap for the trapping of another animal.

  • Patent number: 4748766
    Abstract: A self-resetting animal trap utilizing a closed-door approach wherein the trap is set or ready when its trap door is closed. The self-resetting animal trap has an enclosure with a top opening and a pivotally mounted trap door for the top opening. A metal plate is attached to the trap door frame beneath the trap door such that the trap door has an upwardly and downwardly pivoting portion. A magnet is slideably mounted to the underside of the upwardly pivoting portion such that the magnet is in contact with the metal plate when the trap door is closed. The magnet and the metal plate form the trigger mechanism for the trap. The weight of the magnet also urges the trap door toward a set-closed position from a tripped-open position, thereby resetting the trap. A bait container is positioned near the end of the downwardly pivoting portion. A chute is also provided allowing approach to the bait container only via the trap door.

  • Patent number: 4706408
    Abstract: A rodent trap comprises a trough connected to an elongated platform forming an obtuse angle therebetween. Mounting means having a traverse groove is affixed at an apex formed by the trough and the platform. A supporting wire of a wire structure fits into the groove to assemble the trap. The wire structure is clamped on the rim of a bucket, partially filled with water. Marbles are placed in the back end of the trough and the trap is set in a tilt-back position. When a rodent approaches the bait set on the platform, the platform tilts forward and down, triggering the marbles to roll forward to the front end of the trough thereby accelerating the rapid tilting of the platform, thus dropping the rodent off the platform.

  • Patent number: 4706407
    Abstract: An animal trap especially suited for trapping rodents such as rats and other small animals, in one embodiment comprising a generally cylindrical or rectangular container having a movable top adapted for limited rotation in one direction about a pair of centrally positioned fulcrum points in response to the animal's weight on one side of the top on which is provided a suitable bait. The top is normally positioned horizonally fully covering the interior of the container. Upon activation of the top in response to the animal's weight on the trigger side of the top, the top rotates to a substantially vertical position causing the animal to fall into the container and permitting the top to reset itself horizontally for trapping another animal. The trap is preferably configured to cause the animal to have all of his weight on the non-trigger side of the top before it goes after the bait on the trigger side of the top.

  • Patent number: 4662101
    Abstract: A mousetrap (10) is made of a pivoting platform (12) suspended over a pitfall (14). The platform (12) is balanced in a manner such that it normally assumes a horizontal position, thus giving a mouse an appearance of a stable bridge over the pitfall. When the mouse (42) steps onto the platform (12) for the purpose of obtaining bait placed thereon, however, the platform (12) spins and dumps the mouse into the pitfall thereby trapping it.

  • Patent number: 4610105
    Abstract: A trap for catching rodents and other pests in permitting the user to selectively trap the same alive or dispose of them at the time of trapping. A container is provided having bottom and side walls and defining an opening at the upper portion thereof. A closure number is pivotally supported by a wall portions of the enclosure and is pivotal, responsive to the weight of a rodent or pest, causing the same to fall into the enclosure. The enclosure may contain water or any other material suitable for eratication. The closure structure defines a bait containing depression in which a protein containing bait such as grain may be placed to lure rodents onto the closure. The closure is urged to its substantially horizontal, closed position by a counterweight or other urging device mounted on the closure.

  • Patent number: 4151673
    Abstract: An animal trap includes a box-like housing having a capture compartment and a storage compartment. An elevated access opening is presented on one side of the housing and is adjacent to a primary platform which is pivotally mounted in the capture compartment and has a normal, level condition and a tilted, capture position. In its normal condition, the primary platform blocks passage to the storage compartment; in its tilted position the elevated access opening is blocked and the storage compartment is accessible. A tilt booster is carried by the primary platform and presents a secondary platform or plank arranged on a fixed fulcrum in a manner to cause sudden tilting of the primary platform under the weight of an animal and blocks its escape.
