Device for preventing backlash on spool of fishing reel

Claim 2

In a double shaft support fishing reel having provisions for preventing spool backlash: (a) first and second side frame members; (b) strut means securing at opposite ends thereof, said side frame members to define a cage for a spool; (c) first and second side plates detachably secured to the first and second side frame members respectively; (d) a spool having a shaft; (e) first spool shaft support means carried by said first side plate; (f) spool shaft driving means accommodated in said first side plate; (g) a mounting disc having a peripheral rim fitted between and engaging both said second side plate and said second frame member, said mounting disc having means registering said disc with said second frame member, said rim being confined to its fitted relationship by said second side plate; (h) second spool shaft support means fitted to said mounting disc whereby the transverse bearing load of spool shaft is transmitted directly to said second frame member through said registering means, said transverse bearing load thereby bypassing said second side plate, said first and second shaft support means being aligned and together defining an axis of rotation of said spool shaft; (i) magnetic field forming means carried entirely by said mounting disc and detachable therewith, said magnetic field forming means being directly opposed to the corresponding end of said spool; and (j) an electrically conductive annular eddy current member carried by said spool and projecting into the magnetic field formed by said magnetic field forming means whereby a magnetic drag is imposed upon said spool as a function of its rotational speed.

Claim 3

The fishing reel as set forth in claim 1 in which said magnetic field forming means includes an element mounted on said disc for angular movement about said axis to vary the operative strength of said magnetic field and correspondingly, the magnetic drag imposed upon said spool; and a manually movable adjustment member carried with said end plate and engageable with said element selectively to determine the angular position of said element.

Claim 4

The fishing reel as set forth in claim 2 in which said adjustment member includes a pinion gear and said element includes a spur gear with a gear ratio therebetween sufficient to provide a one way drive for stability of said element; said magnetic field forming means comprising permanent magnets mounted on said element and said disc respectively, there being an annular space therebetween, said annular member projecting into said annular space; angular movement of said element changing the alignment of said magnets on opposite sides of said space whereby the strength of the magnetic field is varied.

Claim 5

The fishing reel as set forth in claim 1 in which said spool shaft has an end projecting through said mounting disc and through said second spool shaft support means; a click gear mounted on said projecting spool shaft end; and a click pawl retractably mounted on said second end plate for selective engagement with said click gear.

Claim 8

In a double shaft support fishing reel having provisions for preventing spool backlash: (a) first and second side frame members; (b) strut means securing at opposite ends thereof, said side frame members to define a cage for a spool; (c) first and second side plates detachably secured to the first and second side frame members respectively; (d) a spool having a shaft; (e) first spool shaft support means carried by said first side plate; (f) spool shaft driving means accommodated in said first side plate; (g) a mounting disc having a peripheral rim fitted between said second side plate and said second frame member, said mounting disc having means registering said disc with said second frame member, said rim being confined to its fitted relationship by said second side plate; (h) second spool shaft support means fitted to said mounting disc, said first and second shaft support means being aligned and together defining an axis of rotation of said spool shaft; (i) magnetic field forming means carried entirely by said mounting disc and detachable therewith, said magnetic field forming means being directly opposed to the corresponding end of said spool; and (j) an electrically conductive annular eddy current member carried by said spool and projecting into the magnetic field formed by said magnetic field forming means whereby a magnetic drag is imposed upon said spool as a function of its rotational speed; (k) said spool shaft having an end projecting through said mounting disc; (l) a click gear mounted on said projecting spool shaft end; and (m) a click pawl retractably mounted on said second end plate for selective engagement with said click gear; (n) said second shaft support means being carried on said spool shaft; (o) said mounting disc providing a central aperture larger than the diameter of said click gear for detachment of said mounting disc while said click gear is in place on the projecting end of said spool shaft.

Claim 9

In a double shaft support fishing reel having provisions for preventing spool backlash: (a) first and second side frame members; (b) strut means securing at opposite ends thereof, said side frame members to define a cage for a spool; (c) first and second side plates detachably secured to the first and second side frame members respectively; (d) a spool having a shaft; (e) first spool shaft support means carried by said first side plate; (f) spool shaft driving means accommodated in said first side plate; (g) a mounting disc having a peripheral rim fitted between said second side plate and said second frame member, said mounting disc having means registering said disc with said second frame member, said rim being confined to its fitted relationship by said second side plate; (h) second spool shaft support means fitted to said mounting disc, said first and second shaft support means being aligned and together defining an axis of rotation of said spool shaft; (i) magnetic field forming means carried entirely by said mounting disc and detachable therewith, said magnetic field forming means being directly opposed to the corresponding end of said spool; and (j) an electrically conductive annular eddy current member carried by said spool and projecting into the magnetic field formed by said magnetic field forming means whereby a magnetic drag is imposed upon said spool as a function of its rotational speed; (k) said spool shaft having an end projecting through said mounting disc; (l) a click gear mounted on said projecting spool shaft end; and (m) a click pawl retractably mounted on said second end plate for selective engagement with said click gear; (n) said second shaft support means being carried on said spool shaft; (o) said mounting disc providing a central aperture larger than the diameter of said click gear for detachment of said mounting disc while said click gear is in place on the projecting end of said spool shaft.
