ABSTRACT:
A magnetic brake for braking the line spool of a fishing reel with magnetic braking automatically adjusted in dependence upon the speed of rotation of the line spool. A magnetic support for magnets is rotatable in one direction by the reactive force of the braking torque on the magnet support and in the opposite direction by an adjustable spring load. The reactive force of the braking torque tends to displace the magnet support in a direction to move the magnet poles away from a surface rotating together with the line spool, while the spring load tends to displace the magnet support in the opposite direction to decrease the distance between pole ends and the rotating surface moving with the line spool. Inclined camming grooves in one embodiment move along a guide pin to cause the rotating action of the magnet support to move the support in an axial direction. Another embodiment uses a sector support with magnets radially extending from the support and moving toward and away from a flanged surface while mounted on an eccentrically mounted sector.
