Abstract
Abstract A fly reel has a line spool rotatably mounted within a housing. A brake means to resist rotation of the spool in at least one direction employs a drum rotatable with the spool in at least that direction in which rotational resistance is desired. A shoe means incorporated on a brake arm supported from the housing frictionally engages the drum and an adjusting means selectively varies the pressure with which the shoe engages the drum. The adjusting means comprises a wedge means that transmits pressure force from a thrust means to a reaction surface on the side of the brake arm opposite the shoe means. A control means varies the span of the wedge means between the thrust means and the reaction surface and thereby the pressure force applied by the shoe means against the drum.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
209 words
A brake adjusting mechanism for a fishing reel having a frame, a line spool rotatably mounted in said frame, a brake means to resist rotation of said line spool in at least one direction with respect to the frame, said brake means being adjustable by selective variation of the pressure applied thereto, the adjusting mechanism by which said pressure is selectively varied comprising, a reaction surface on said brake means to receive a brake actuating pressure force, a thrust means to provide said pressure force, said thrust means mounted in opposition to and spaced from said reaction surface, wedge means of selectively variable span interposed between said thrust means and said reaction surface to transmit pressure force therebetween, an aperture in said frame, said wedge means carried on a shaft means mounted in said aperture, control means operatively connected to said wedge means selectively to vary the span of said wedge means between said thrust means and said reaction surface concomitantly to vary the pressure force applied against said reaction surface, said aperture having an elongate axis along which said shaft is movable to permit adjustment of the location of said shaft as the span of said wedge means is varied between said thrust means and said reaction surface.
Claim 2
Dependent Claim
209 words
A brake adjusting mechanism for a fishing reel having a frame, a line spool rotatably mounted in said frame, a brake means to resist rotation of said line spool in at least one direction with respect to the frame, said brake means being adjustable by selective variation of the pressure applied thereto, the adjusting mechanism by which said pressure is selectively varied comprising, a reaction surface on said brake means to receive a brake actuating pressure force, a thrust means to provide said pressure force, said thrust means mounted in opposition to and spaced from said reaction surface, wedge means of selectively variable span interposed between said thrust means and said reaction surface to transmit pressure force therebetween, an aperture in said frame, said wedge means carried on a shaft means mounted in said aperture, control means operatively connected to said wedge means selectively to vary the span of said wedge means between said thrust means and said reaction surface concomitantly to vary the pressure force applied against said reaction surface, said aperture having an elongate axis along which said shaft is movable to permit adjustment of the location of said shaft as the span of said wedge means is varied between said thrust means and said reaction surface.
Claim 3
Dependent Claim
38 words
A brake adjusting mechanism, as set forth in claim 1, in which the wedge means employs a disc having successively varied diametric spans, and said control means is secured to said shaft means selectively to rotate said disc.
Claim 4
Dependent Claim
32 words
A brake adjusting mechanism, as set forth in claim 2, in which the elongate axis of said journal aperture is oriented to extend generally between said thrust means and said reaction surface.
Claim 5
Dependent Claim
44 words
A brake adjusting mechanism, as set forth in claim 3, in which the thrust means comprises a plunger means reciprocally mounted in the reel frame said plunger means engaging the peripheral wall of said disc and baising means urging said plunger against said disc.
Claim 6
Dependent Claim
53 words
A brake adjusting mechanism, as set forth in claim 4, in which a barrel means is mounted in said frame and said plunger means is reciprocal therein and in which means are provided selectively to position said barrel means axially of said disc to predetermine the range through which the brake is adjustable.
Claim 7
Dependent Claim
23 words
A brake adjusting mechanism, as set forth in claim 5, in which resilient blocking means retain said barrel means in the selected position.
Claim 8
Dependent Claim
21 words
A brake adjusting mechanism, as set forth in claim 5, in which means are provided selectively to vary said biasing means.
Claim 9
Dependent Claim
72 words
A brake adjusting mechanism, as set forth in claim 5, in which said plunger is reciprocally slidable in a cavity within said barrel means, said cavity having a base wall, said plunger having a stem, a guide bore opening through the base wall of said cavity, said stem being slidably received in said guide bore, said biasing means comprising O-rings embracing said stem and compressible between said plunger and said base wall.
