Abstract
Abstract A braking system for a rotating spool casting reel comprising a pair of diametrically opposed weights that are driven outward by centrifugal force, opposed by tension springs. At the beginning of the cast, the weights are driven outward into cooperation with an outer braking medium to produce an initial drag. As rotation decelerates, the drag decreases until the springs bring the blocks into engagement with an inner cylindrical surface that produces a substantial frictional drag to bring the spool to a stop to minimize the chance of overrun. Either the weights or adjacent reel housing is provided with magnet means and the other is made with electrically conductive material to augment the braking action.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
133 words
In a rotating spool casting reel including: a body; a shaft rotatable in said body; and a spool fixed on said shaft to rotate therewith; the improvement comprising: a carrier fixed on said shaft to rotate therewith; at least one block radially movable on said carrier; an inner, cylindrical brake surface slidably engagable by each said block; spring means biasing each said block radially inward toward said inner brake surface; said spring means being opposed by centrifugal force when said shaft and carrier are rotating; and interacting braking media on each of said blocks and on said body operative to apply an increased retardation force to movement of said blocks when said carrier is rotated; one of said media comprising a magnet and the other of said media comprising an electrically conductive material.
Claim 2
Dependent Claim
133 words
In a rotating spool casting reel including: a body; a shaft rotatable in said body; and a spool fixed on said shaft to rotate therewith; the improvement comprising: a carrier fixed on said shaft to rotate therewith; at least one block radially movable on said carrier; an inner, cylindrical brake surface slidably engagable by each said block; spring means biasing each said block radially inward toward said inner brake surface; said spring means being opposed by centrifugal force when said shaft and carrier are rotating; and interacting braking media on each of said blocks and on said body operative to apply an increased retardation force to movement of said blocks when said carrier is rotated; one of said media comprising a magnet and the other of said media comprising an electrically conductive material.
Claim 3
Dependent Claim
39 words
The combination defined by claim 1 wherein: said blocks are of an electrically conductive material; and said outer braking medium in an annular magnet fixed to said body and disposed coaxial with, and outward of, said inner brake surface.
Claim 4
Dependent Claim
42 words
The combination defined by claim 1 wherein: said blocks are magnets; and said body is of an electrically conductive material; a wall of said body extending generally radially of said shaft so that magnetic force increases as said blocks move radially outward.
Claim 5
Dependent Claim
34 words
The combination defined by claim 1 wherein: said carrier is a disc; means forming a pair of aligned radial slots in said disc; there being a block slidable in each of said radial slots.
