Patent ID: 7490433

Claim:
A fly-fishing apparatus for flowing water comprising: a fly-fishing leader having a length; a fly connected to the leader; and a hook-setting and strike-indicating device fastened to the leader, said device comprising: a single cup-shaped flange having a central axis and a radial dimension, the flange being fixed to the leader so that said central axis is parallel to the length of said leader and said radial dimension extends transverse to the length of the leader; wherein the flange has a concave front surface facing the fly and defining a flange interior space, and the flange has a convex rear surface with a recess comprising an axial side wall and a radial bottom wall, wherein a slot extends through said flange at said radial bottom wall and wherein a portion of the slot is located at said central axis; a single float having a front end, a rear end, a float axis extending between said front end and said rear end, a sidewall generally parallel to said float axis, and a slit extending between said front end and rear end from said sidewall to said float axis, wherein said front end of the single float is received inside said recess so that the float axis is coaxial with said central axis of the flange; wherein said slot in said radial bottom wall and said slit of the float receive a portion of said leader so that the leader extends coaxial with the flange central axis and the float axis; and wherein the device further comprises: an elongated elastic grip member having a grip front end and a grip rear end, the elastic grip member fastening said single float to said single flange and also fastening said float and flange to the leader, wherein the elastic grip member extends through said slot in the radial bottom wall and through the float slit and frictionally grips said portion of the leader received in said slot and said slit for said fastening of said float and flange to the leader, wherein said grip front end abuts against a front surface of said radial bottom wall and wherein said grip rear end abuts against the rear end of the float to hold the float in said recess; wherein the entire hook-setting and strike-indicating device is fixed to the leader a set distance from the fly by means of said grip member frictionally gripping the portion of said leader that is received inside the flange slot and the float slit, so that no part of the hook-setting and strike-indicating device slides along the leader during or after casting and so that no part of the hook-setting and strike-indicating device slides along the leader during or after a fish strike.
