Micro external adjustable spool braking system

1. A device comprising:

a spool rotatable about an axis in a reel;

a braking structure that effects a braking force against rotation of the spool, the braking force being adjustable by changing a proximity of the braking structure relative to the spool;

at least one tap in a fixed relationship with respect to the braking structure; and

a brake dial accessible outside the reel, said brake dial defining an exterior circumference and providing a threaded portion that defines threads that wrap around said exterior circumference greater than once, said threads for accepting the at least one tap, the brake dial being rotatable to change the proximity of the braking structure relative to the spool by movement of the tap.

2. The device of claim 1 , further comprising:

a spool cap providing a bearing on a first side thereof, the bearing carrying a spool shaft proceeding from the spool along the axis;

wherein the spool cap is in a fixed relationship with respect to the reel and rotationally fixed, but not axially fixed, with respect to the braking structure located on the first side of the spool cap;

wherein the spool cap abuts the brake dial on a second, opposite side of the spool cap; and

wherein the spool cap provides at least one opening for the at least one tap to reach the threaded portion of the brake dial, the opening being sized to allow axial longitudinal movement of the tap.

3. The device of claim 2 , further comprising:

an end cap affixed to the reel;

wherein the spool cap is affixed to the end cap with the brake dial interposing the spool cap and end cap; and

wherein the end cap defines an opening to allow user rotation of the brake dial.

4. The device of claim 2 , wherein the braking structure comprises a brake ring element carrying a braking surface that selectively engages with a plurality of radially placed and centrifugally extensible braking elements contained in a braking element structure affixed to the spool.

5. The device of claim 4 , wherein the radially placed braking elements are staggered longitudinally along the axis of rotation of the spool such that a number of braking elements engaging the braking surface depends upon the proximity of the brake ring element to the spool.

6. The device of claim 2 , wherein the braking structure is rotationally fixed with respect to the spool cap by at least one arm providing at least one receptacle in longitudinal sliding engagement with at least one boss extending from the spool cap toward the spool.

7. The device of claim 2 , wherein the braking structure comprises a magnet carrier with a plurality of magnets facing the spool.

8. The device of claim 7 , wherein the magnet carrier is rotationally fixed with respect to the spool cap by at least one post in sliding engagement with at least one receptacle in the spool cap.

9. A device comprising:

a spool rotatable about an axis passing through a reel frame;

a brake element retaining structure affixed to the spool about the axis and providing a plurality of radially arranged and axially longitudinally staggered braking elements that extend radially from the brake element retaining structure under centrifugal force;

a brake ring structure providing a braking surface that selectively engages more or fewer of the plurality of the braking elements when the same are under centrifugal extension depending upon the proximity of the brake ring structure to the spool;

at least one tap provided on an arm extending from the brake ring structure; and

an exteriorly threaded brake dial defining an exterior thread for receiving the at least one tap and operable to adjust the proximity of the brake ring structure to the spool by rotation of the brake dial, said exterior thread wrapping around said brake dial greater than once.

10. The device of claim 9 , further comprising:

a spool cover in a fixed relationship with respect to the reel frame;

wherein the spool cover interposes the brake dial and the brake ring structure; and

wherein the spool cover provides at least one cutout therein allowing the at least one tap provided by the brake ring structure to fit into the threaded brake dial.

11. The device of claim 10 , wherein the spool cover provides at least one boss that receives, in sliding engagement, at least one receptacle defined in at least one receptacle arm extending from the brake ring structure thereby allowing axial longitudinal movement of the brake ring structure but preventing rotational movement.

12. The device of claim 10 , wherein the spool cover provides a bearing that receives a shaft from the spool in rotational engagement.

13. The device of claim 10 , further comprising an external end cover in a fixed relationship with respect to the reel frame and the spool cover.

14. The device of claim 13 , wherein the brake dial interposes the spool cover and the external end cover, the external end cover defining an opening allowing user access to the brake dial.

15. A device comprising:

a spool rotatable about an axis passing through a reel frame;

a magnetic braking structure having a plurality of magnets for retarding the rotation of the spool in varying degrees depending upon the proximity of the magnetic braking structure to the spool;

at least one tap extending from the magnetic braking structure; and

an exteriorly threaded brake dial defining an exterior thread for receiving the at least one tap and operable to adjust the proximity of the magnetic braking structure to the spool by rotation of the brake dial, said exterior thread wrapping around said brake dial greater than once.

16. The device of claim 15 , further comprising a spool cap in a fixed relationship with respect to the reel frame, the spool cap interposing the brake dial and the magnetic braking structure and defining a longitudinal opening allowing the tap to pass to the threaded brake dial.

17. The device of claim 16 , wherein the magnetic braking structure is rotationally fixed with respect to the spool cap by at least one post extending from the magnetic braking structure into sliding engagement with at least one receptacle defined in the spool cap.

18. The device of claim 16 , further comprising a shaft bearing affixed to the spool cap that receives, in a rotational engagement, a shaft proceeding from the spool.

19. The device of claim 16 , further comprising an exterior cover affixed to the frame and to which the spool cap is affixed.

20. The device of claim 19 , wherein the brake dial interposes the exterior cover and the spool cap, the exterior cover defining an opening allowing user access to the brake dial.
