Crab pot with positive trigger mechanism

Year	Description
1996	Invention patented by Leonard W. Mattson and Elmer James Mattson on October 22th, 1996. Abstract: A crab pot provided with a plurality of entrance tunnels each having a rectangular opening frame, utilizes the top rod of the opening frame to pivotally support a plurality of wire trigger fingers which extend vertically downward for abutment against the bottom rod of the opening frame. Pairs of such trigger fingers are formed of a single length of wire coiled intermediate its ends about the top rod of the opening frame to form a pair of pivots for the fingers, the intermediate length of wire between the coils forming legs extending downward from the coils and joined together by a span of the wire. The trigger fingers are urged gravitationally toward the position closing the rectangular tunnel opening. A limit rod projects from the top rod of the opening frame to intercept the span of wire and limit opening movement of the trigger fingers to less than 180.degree..
