Patent ID: 8402687

Claim:
An artificial fishing-lure head ( 20 ) having an alterable swimming action which is manually adjustable without having to cut the line or else add or remove parts, comprising: an axially-elongated body ( 22 ) extending axially between a leading rim ( 26 ) and a trailing end ( 28 ), the body ( 22 ) formed through the leading rim ( 26 ) with a recessed-in axially-elongated fore chamber ( 58 ) that is formed with coupling formations; an axially-elongated insert therefor not only extending between a non-concave leading end ( 64 ) and a trailing end ( 66 ) but also being formed with counterpart coupling formations as well as with an axial line-threading through hole ( 134 ) so that said insert slides or threads on fishing line ( 34 ) in free sliding fashion except, even while the fishing line ( 34 ) is allowed to trail out the body ( 22 )'s trailing end ( 28 ), the lure head ( 20 ) is adapted to be stopped from sliding off rearwardly after trailing tackle ( 38 ) is rigged in place; said insert coupling the fore chamber ( 58 ) such that said insert axially travels between extended and retracted extremes in the fore chamber ( 58 ); wherein the retracted extreme comprises the insert's leading end ( 64 ) withdrawn rearward of the body ( 22 )'s leading rim ( 26 ), and the extended extreme comprises the insert's leading end ( 64 ) exposed forward of the body ( 22 )'s leading rim ( 26 ); wherein the retracted extreme has insert's leading end ( 64 ) less involved with lure head ( 20 )'s swimming action than the body ( 22 )'s leading rim ( 26 ), which consequently dominates and presents a concave face for the lure head ( 20 ) and as such the lure head ( 20 ) is adapted to produce a porpoising swimming action in a fairly straight line; wherein the extended extreme, in contrast, has the insert's leading end ( 64 ) dominating the influence over the lure head ( 20 )'s swimming action and as such the lure head ( 20 ) is adapted to produce a distinct alternate swimming action for the lure head ( 20 ); said insert being operatively adjustable in the fore chamber ( 58 ) by the coupling formations and counterparts thereto to hold a fixed position among a range of positions between said extremes in order to change the swimming action of the lure head ( 20 ) from not just porpoising in a fairly straight line nor simply else the distinct alternate swimming action for the lure, but also along a gradation of hybrid swimming actions therebetween, and all without having to cut the line ( 34 ) after the trailing tackle ( 38 ) is rigged in place, or else add or remove parts.
