  • Patent number: 4196884
    Abstract: The present fishing lure has a molded elastomeric body with a deep, narrow, longitudinal recess in which the curved hook end of a fishhook is concealed. The present apparatus for making this lure includes an insert for forming this recess which is separate from the molding dies and is removable from the elastomeric body after the latter has been molded. The fishhook may be part of this insert, so as to be molded in place in the lure body, or it may be inserted into the lure body after the latter has been molded. In one embodiment the removable insert forms an inclined passageway for passing water up from the bottom of the lure body into its aformentioned recess to impart a wiggling motion to the lure as it moves through the water.

A reciprocable plunger extends into the mold cavity at one end to form an anchoring recess for a metal or plastic head that is to be attached to this end of the elastomeric lure body and also to form a passageway leading to the bottom of the recess formed by the rib for receiving the shank of the fishhook.
