Abstract

There is provided an animal trap construction, in which a coil spring is adapted, upon springing of the trap, to cause a swing arm to pivot upwardly through a vertical arc, and tighten a noose around the leg of an animal. The coil spring is contained between two upstanding brackets, and an end portion of the swing arm, bent at right angles to the latter, passes centrally through the spring, and passes through the two brackets. A first bushing of cylindrical form is fixed within the end of the spring remote from the bend location between the swing arm and its end portion, the first bushing having a smaller-diameter cylindrical extension passing through an aperture in the respective bracket. A second bushing is provided at the other end of the coil spring, the second bushing having a flange which is adapted to be located between the coil spring and the respective bracket. The end portion of the swing arm passes through both bushings. The second bushing has a rib of annular form, extending toward and contacting the respective bracket, in order to reduce friction between the second bushing and its respective bracket.
