Abstract
A line reel includes a spool for line, a drive shaft effecting rotation of the spool through suitable gears and a manually operable crank hinged to the drive shaft. The drive shaft has a clutch part releasably engageable with a cooperating clutch part on one of the gears. A cam surface on the crank causes the crank, when pivoted to a selected locked or cranking position, to be moved to an over-center position at which a spring holds the crank in selected position. In locked position, the clutch parts are disengaged and the spool stops are engaged. In cranking position, the clutch parts are engaged and the stops are disengaged. The crank may be moved to disengage both the stops and the clutch parts so that the wound line may be manually extended from the spool without effecting rotation of the crank.
Claims13
In a line reel including a spool for winding line thereabout, a case in which the spool is rotatably mounted and having an aperture through which the line extends, and gear means in engagement with the spool for driving the spool to wind or unwind line thereon, the improvement comprising:
- a clutch part carried by the gear means;
- a rotatable shaft for driving the gear means having a complementary clutch part at one end adapted to releasably engage the clutch part on the gear means and having its other end external of the case, said shaft being movable between a first position in clutched engagement with the gear means and a second position disengaged from the gear means;
- means for biasing said shaft into clutched engagement with the gear means;
- and
- a crank for turning said shaft having one end pivotally connected to the external end of said shaft for selective pivotal movement between cranking and locked positions, said crank defining cam means at the one end thereof adapted to engage the case, said cam means being eccentric relative to the pivot connection between the crank and shaft so that said crank is maintained by the action of said biasing means at a selected one of said cranking and locked positions, said cam means maintaining said shaft in disengaged position when said crank is at its locked position and permitting said biasing means to move said shaft to engaged position when said crank is at its cranking position.
In a line reel including a spool for winding line thereabout, a case in which the spool is rotatably mounted and having an aperture through which the line extends, and gear means in engagement with the spool for driving the spool to wind or unwind line thereon, the improvement comprising:
- a clutch part carried by the gear means;
- a rotatable shaft for driving the gear means having a complementary clutch part at one end adapted to releasably engage the clutch part on the gear means and having its other end external of the case, said shaft being movable between a first position inward of the case to engaged relation with the gear means clutch part and a second position outward from the case to disengaged relation with the gear means clutch part;
- spring means for biasing said shaft inward of the case to engage the shaft clutch part with the gear means clutch part;
- a crank for turning said shaft having one end pivotally connected to the external end of said shaft for selective pivotal movement between said cranking and locked positions, said crank having a peripheral cam surface at the one end thereof adapted to engage the case, said cam surface being eccentric relative to the pivot connection between the crank and shaft so that said crank is maintained by the action of said spring means at a selected one of said cranking and locked positions, said cam surface maintaining said shaft in disengaged position when said crank is at its locked position and permitting said spring means to move said shaft to engaged position when said crank is at its cranking position;
- exposed stop lugs carried by the gear means;
- a complementary stop member carried by said crank for engaging one of the stop lugs of the gear means when said crank is at its locked position to prevent rotation of the gear means and hence the spool;
- and
- a camming ramp surface carried by the case and adapted to engage said crank when said crank is at its locked position and is turned, turning movement of said crank causing said crank to ride up the ramp surface as it is biased thereagainst by said spring means so as to lift the stop member away from said stop lugs while maintaining disengagement of said clutch parts to permit the spool to rotate independently of said crank, said spring means returning said crank to its locked position when said crank is released.
