Dubbing assembly in fly hook production

Abstract

A machine for dubbing assembly in fly hook production includes a base having a vertical dowel mounted to one end of the base, and a housing mounted to the other end. A work platform is pivotally mounted to one side of the base so that the platform may be elevated or lowered. A drive motor is mounted within the housing. The motor drives a drive shaft. The drive shaft terminates in a hook or eye. A second eye is mounted to the vertical dowel. The second eye projects toward, in opposed facing relation with, the drive shaft. The second eye supports a tensioning spring which has a barrel swivel attached to its opposite end. One or more filaments may be attached to a ring on the barrel swivel so as to extend across the work platform and be secured to the hook or eye on the drive shaft. Dubbing material is applied to a single filament or sandwiched between double strand filaments. Double strand filaments are twisted into a helix to flare the dubbing material.

What is claimed is:  
     
         1 . A dubbing brush made by a method including the steps of: 
 (a) providing a base having first and second opposite ends;    (b) providing a motor mounted on said first end of said base and a driveshaft coupled to said motor, said motor being intended for rotating said driveshaft at a selectable constant rotation speed about an axis of rotation;    (c) providing a rigid support mounted at said second end of said base, a resilient biasing means mounted to said rigid support, and a coupling mounted to said resilient biasing means in opposite relation to said rigid support and in opposed facing relation to said driveshaft;    (d) providing said driveshaft and said coupling on said axis of rotation;    (e) securing respective ends of a double strand filament to said driveshaft and said coupling so as to tension said filament therebetween and so as to maintain strands of said double strand filament snugly adjacent and parallel, wherein said strands are of a permanently deformable material which remains flexible when twisted;    (f) spreading an array of hair-like dubbing material fibres generally evenly along, so as to be generally perpendicular to and sandwiched between said strands;    (g) actuating said motor so as to twist said filament about said axis of rotation, thereby permanently twisting said strands around one another, whereby said dubbing material fibres are anchored between said strands and rotated about said axis of rotation to form a hairy three dimensional body of revolution about said axis of rotation;    (h) brushing-out said fibres as they twirl and flare as said filament is twisted; and    (i) removing said filament from said driveshaft and said coupling so as to allow said hairy three dimensional body of revolution to flex and bend along its length for use in fly tying.    
     
     
         2 . A method of making a dubbing brush, comprising the steps of: 
 (a) providing a base having first and second opposite ends;    (b) providing a motor mounted on said first end of said base and a driveshaft coupled to said motor, said motor being intended for rotating said driveshaft at a selectable constant rotation speed about an axis of rotation;    (c) providing a rigid support mounted at said second end of said base, a resilient biasing means mounted to said rigid support, and a coupling mounted to said resilient biasing means in opposite relation to said rigid support and in opposed facing relation to said driveshaft;    (d) providing said driveshaft and said coupling on said axis of rotation;    (e) securing respective ends of a double strand filament to said driveshaft and said coupling so as to tension said filament therebetween and so as to maintain strands of said double strand filament snugly adjacent and parallel, wherein said strands are of a permanently deformable material which remains flexible when twisted;    (f) spreading an array of hair-like dubbing material fibres generally evenly along, so as to be generally perpendicular to, and sandwiched between said strands;    (g) actuating said motor so as to twist said filament about said axis of rotation, thereby permanently twisting said strands around one another, whereby said dubbing material fibres are anchored between said strands and rotated about said axis of rotation to form a hairy three dimensional body of revolution about said axis of rotation;    (h) raking said fibres as they twirl and flare as said filament is twisted; and    (i) removing said filament from said driveshaft and said coupling so as to allow said hairy three dimensional body of revolution to flex and bend along its length for use in fly tying.    
     
     
         3 . A double strand dubbing brush, comprising: 
 (a) a helix core of two permanently twisted flexible elongate members; and    (b) an array of fibres, spread along and sandwiched between said two permanently twisted flexible elongate members, said array being generally bisected by said helix core and said array being flared so as to extend radially and uniformly densely about said helix core and uniformly distributed along said helix core.    
     
     
         4 . The dubbing brush of  claim 3  wherein said flexible elongate members are wire.  
     
     
         5 . The dubbing brush of  claim 3  wherein a majority of said fibres in said array are of uniform thickness and length, and wherein said fibres have been stacked and brushed out during twisting formation of said helix core.  
     
     
         6 . The dubbing brush of  claim 3  wherein a majority of said fibres in said array are of uniform thickness and length, and wherein said fibres have been stacked and raked out during twisting formation of said helix core.  
     
     
         7 . A fly hook made by a method including the steps of: 
 winding a dubbing brush according to either  claim 1  or  claim 2  around a shank of a hook to form a body,    trimming a first portion of said body, and    brushing out said body over a remaining portion of said body.    
     
     
         8 . The fly hook of  claim 7  further comprising a tail mounted to said shank of said hook, wherein said tail is a second said dubbing brush having one end thereof mounted to said shank so as to trail said tail from said shank.  
     
     
         9 . A fly hook made by a method including the steps of: 
 winding a dubbing brush according to either  claim 1  or  claim 2  around a shank of a hook to form a body,    trimming a first portion of said body, and    raking out said body over a remaining portion of said body.    
     
     
         10 . The fly hook of  claim 9  further comprising a tail mounted to said shank of said hook, wherein said tail is a second said dubbing brush having one end thereof mounted to said shank so as to trail said tail from said shank.
