Abstract: A self-setting fish hook assembly includes an arm biasing spring to spread to hooks placed on first and second extending arms. A latch spring is mounted on one of the extending arms to hold the two extending arms together until a fish bites on both of the hooks and causes the extending arms to move momentarily closer together. This frees the latch spring to spring clear of the second extending arm and allows the arm biasing spring to unload, thereby spreading the two hooked arms. An embodiment which uses a coil arm biasing spring separate from the first and second extending arms allows the extending arms to be moved close together without loading the arm biasing spring.

Abstract: Self setting fish hook assembly. A spring has first and second extending arms, the spring being arranged to force the arms apart. First and second barbed hooks are mounted on the first and second arms. A latch spring is mounted on the first arm, the latch spring has a first extending member with a shallow hook portion at its end and a second extending member longer than the first extending member. The hook portion is arranged to hold the second arm in compressed position and adapted to release the second arm when the first and second arms are compressed by a fish biting on them. The second extending portion is arranged to snap the hook portion away from the arm being held when the first and second arms are compressed.
