Abstract
Abstract A clutch mechanism for a fishing reel wherein the shaft supporting the spool is selectively engaged and disengaged from the drive mechanism through a clutch. The clutch also actuates a spring bias link having an opening therein that includes a stepped and elongated portion. A kick pawl pivotally affixed to the link is disposed to lie between the teeth of a ratchet which is driven by the handle of the fishing reel. Upon turning the handle, the kick pawl moves the link such that the projection moves into the elongated portion of the opening in the link, thereby allowing a spring that biases the clutch to engage the pinion gear with the spool shaft.

Claim 1
Independent Claim
379 words
A clutch mechanism for a fishing reel comprising: frame means for supporting components of said reel in an operative arrangement; a spool for storing and dispensing fishing line therefrom, said spool being rotatable held by said frame means; means for driving said spool; a spool shaft connected to and rotatable with said spool; a pinion gear; control means for selectively engaging said pinion gear to drive said spool, said control means including an actuating lever and cam means connected to said actuating lever, said cam means being rotatably mounted on said frame means for rotating with respect to said pinion gear to engage and disengage said pinion gear and said spool shaft; first spring means urging said cam means to a position where said pinion gear is engaged with said spool shaft; an elongated intermediate link having a first end pivotally connected to said cam means and a second end at an extremity of said link substantially opposite said first end, said link including an opening having a stepped portion and an elongated portion; means for pivotally connecting said first end of said link to said cam means; said frame means including a frame projection extending within said opening and disposed to limit movement of said link when said projection is engaged with said stepped portion of said opening, said stepped portion being engaged with said projection when said pinion gear is disengaged from said spool shaft; second spring means connected between said link and said frame means for biasing said stepped portion of said link into engagement with said projection; a kick pawl pivotally affixed to said second end of said link, said kick pawl having a tip portion spaced from said second end; means for pivotally affixing said kick pawl to said second end of said link; a circular ratchet member connected top said drive means and having a plurality of teeth disposed on an outer peripheral edge thereof; third spring means connected between said kick pawl and said link for biasing said tip portion toward said ratchet member, said tip portion being disposed to lie between said teeth when said pinion gear is disengaged from said spool shaft; and means on said link for limiting the extent of movement of said tip portion toward said ratchet.
Claim 2
Dependent Claim
379 words
A clutch mechanism for a fishing reel comprising: frame means for supporting components of said reel in an operative arrangement; a spool for storing and dispensing fishing line therefrom, said spool being rotatable held by said frame means; means for driving said spool; a spool shaft connected to and rotatable with said spool; a pinion gear; control means for selectively engaging said pinion gear to drive said spool, said control means including an actuating lever and cam means connected to said actuating lever, said cam means being rotatably mounted on said frame means for rotating with respect to said pinion gear to engage and disengage said pinion gear and said spool shaft; first spring means urging said cam means to a position where said pinion gear is engaged with said spool shaft; an elongated intermediate link having a first end pivotally connected to said cam means and a second end at an extremity of said link substantially opposite said first end, said link including an opening having a stepped portion and an elongated portion; means for pivotally connecting said first end of said link to said cam means; said frame means including a frame projection extending within said opening and disposed to limit movement of said link when said projection is engaged with said stepped portion of said opening, said stepped portion being engaged with said projection when said pinion gear is disengaged from said spool shaft; second spring means connected between said link and said frame means for biasing said stepped portion of said link into engagement with said projection; a kick pawl pivotally affixed to said second end of said link, said kick pawl having a tip portion spaced from said second end; means for pivotally affixing said kick pawl to said second end of said link; a circular ratchet member connected top said drive means and having a plurality of teeth disposed on an outer peripheral edge thereof; third spring means connected between said kick pawl and said link for biasing said tip portion toward said ratchet member, said tip portion being disposed to lie between said teeth when said pinion gear is disengaged from said spool shaft; and means on said link for limiting the extent of movement of said tip portion toward said ratchet.
Claim 3
Dependent Claim
68 words
The clutch mechanism as defined in claim 1, wherein said ratchet member is rotated in a first direction by said driving means and wherein rotation of said ratchet member in said first direction, when said stepped portion is engaged with said projection, pivots said tip portion against the bias of said second spring means to urge said elongated portion of said link into engagement with said frame projection.
Claim 4
Dependent Claim
45 words
The clutch mechanism as defined in claim 1, wherein said cam means include a rotatable clutch cam having link means for connecting said clutch cam to said actuating lever, said clutch cam also having pivot means for pivotally connecting said clutch cam to said link.
Claim 5
Dependent Claim
48 words
The clutch mechanism as defined in claim 1, wherein said first spring means includes a first end adapted to be secured on said frame means and a second end attached to said actuating lever enabling said first spring means to apply a unidirectional force to said actuating lever.
Claim 6
Dependent Claim
20 words
The clutch mechanism as defined in claim 1, wherein said limiting means includes a stop member projecting from said link.
