    Abstract: An animal trap having a pair of elongated rods joined to jaws that are bias to a closed position with a coil spring. The coil spring is concentrically located about a pivot pin that pivotally joins the mid-sections of the rods together. An over-centered toggle trip mechanism is pivotally connected to the rods to hold the jaws in their open position. The trip mechanism has a trigger operable by the animal to be trapped to move the over-center toggle trip mechanism to a position wherein it collapses whereby the spring biases the jaws to their closed positions.
