  • Patent number: 4926581
    Abstract: A T-shaped animal trap having entry ports and sliding doors at opposite ends of its head portion and a platform resting on a dowel in its leg portion. A magnet is on each end of the dowel outside of the trap which can magnetically hold to each magnet a flexible metal wire when the entry ports are open, which wire extends into the head portion and is attached to one sliding door. When the platform is moved over the dowel, the dowel partially rotates and the wires are released from the magnets, thereby permitting the sliding doors to close the entry ports. Atlernatively, the animal trap may be tunned shaped with entry ports and sliding doors at opposite ends and a platform resting on a dowel near the middle of the tunnel.
