Audible fish lure

Claim 2

An audible fish lure comprising: (a) A lure body, with an inlet end and an outlet end, having a bore through which water flows from inlet end to outlet end, as the said lure is pulled through the water; (b) Means attached to the lure body for attaching a fishing line thereto; (c) Means attached to the lure body for attaching a fish hook thereto; (d) A solid ball of diameter slightly less than the diameter of said bore with respect to said bore diameter and yet of sufficient diameter so to permit water to flow only around said ball and to cause Bernoulli's principle to effect the ball in said bore to thereby cause steady oscillatory action of said ball; (e) Means approximately midway of the length of said bore for continuously restraining the ball from moving in the direction of flow of the water through the bore, yet still allowing the ball to oscillate back and forth transverse of the flow of water through the bore, and to noisily strike the surface of the bore for providing a hum audible to fish; and, (f) Means for restraining the ball from moving out the inlet end of the bore from a position approximately midway of the bore length.

Claim 3

An audible fish lure as recited in claim 1 wherein said means for restraining the ball from moving in the direction of flow of the water through the bore includes a pin disposed on the side of the ball nearest the outlet end of the bore, and the said means for restraining the ball from moving out the inlet end of the bore includes a pin disposed on the side of the ball nearest the inlet end of the bore, wherein further the said pins each extend across the bore in parallel and through the axis of the bore, and wherein each of the said pins is attached at each of its ends to the lure body.

Claim 4

An audible fish lure as recited in claim 1 wherein the said means for restraining the ball from moving in the direction of the flow of water through the bore includes a rod disposed along the axis of the bore, the said rod having a first end to which is attached the surface of the ball nearest to the outlet end, and said rod having a second end which terminates approximately at the outlet end of the bore, and wherein the said means for restraining the ball further comprises a pivot pin inserted through the lure body transverse to the bore, through the bore, and through the rod, such that the rod is pivotally positioned on the axis of the bore and free to oscillate about the pivot pin.

Claim 5

An audible fish lure as recited in claim 3 wherein the lure body has narrow slots on opposite sides of the bore, parallel to the axis of the bore, and extending between approximately midway the length of the bore and the outlet end of the bore, the pivot pin being disposed within the slots such that the position of the ball and pivot pin is slidably adjustable along the bore, and wherein the diameter of the bore along the bore surface that is within the adjustable contact range of the ball, from the upstream limit of travel of the ball down to the downstream limit of travel of the ball, is reduced from the diameter of the inlet end of the bore down to the diameter of the ball, and wherein the pivot pin further comprises manual means of reversibly attaching the pivot pin to the lure body.

Claim 6

An audible fish lure as recited in claim 4 further comprising means for preventing movement of water through the slots.

Claim 7

An audible fish lure as recited in claim 1, wherein said means for restraining the ball from moving in the direction of flow of the water through the bore includes a pin disposed on the side of the ball nearest to the outlet end of the bore, wherein the said pin extends across the bore and through the axis of the bore, which pin further comprises manual means of reversibly attaching the pin to the lure body, and wherein the lure body has narrow slots on opposite sides of the bore, parallel to the axis of the bore, and extending between approximately midway the length of the bore and the outlet end of the bore, said slots serving as guide supports for the slidable adjustment of the said pin, and wherein the diameter of the bore along the bore surface that is within the adjustable contact range of the ball, from the upstream limit of travel of the ball down to the downstream limit of travel of the ball, is reduced from the diameter of the inlet end of the bore down to the diameter of the ball; and wherein further the means for restraining the ball from moving out the inlet end of the bore is a pin fixed to the lure body on the side of the ball nearest to the inlet end of the bore and extending across the bore.

Claim 8

An audible fish lure as recited in claim 6 further comprising means for preventing movement of water through the slots.
