     DETAILED DESCRIPTION OF THE INVENTION  
       [0040]    [0040]FIG. 1 illustrates a first cross sectional view of a fly fishing reel  50  having a device  17  to engage or release a preset amount of drag (may also be described as “resistance”) from a spool  8  by engaging a taper drag disc  7 , in accordance with embodiments of the present invention. The device  17  may comprise one piece or it may comprise a plurality of pieces. The device  17  may be a trigger (i.e., as shown in FIGS.  1 - 5  and  7 ) or a lever (i.e., as shown in FIG. 6). The device  17  may comprise a metallic alloy or metal including, inter alia, stainless steel or aluminum. The spool  8  may comprise metal including, inter alia, aluminum. The taper drag disc  7  may comprise plastic including, inter alia, Rulon® or Nylon®.  
         [0041]    [0041]FIG. 2 illustrates a second cross sectional view of the fly fishing reel  50  of FIG. 1 having the device  17  to engage or release a preset amount of drag from the spool  8  (shown in FIG. 1 but not shown in FIG. 2) by engaging a drag mechanism comprising a drag preset knob  1 , a spring compressor  2 , a compression spring  4 , and a taper drag disc  7 , in accordance with embodiments of the present invention. The device  17  may be a trigger (i.e., as shown in FIG. 2) or a lever (i.e., as shown in FIG. 6). The device  17  may comprise one piece or it may comprise a plurality of pieces. The device  7  may include a tapered drag surface  95 . The spool  8  is attached to a spool engagement shaft  9  that is attached to a spline hub  15 . A keyed engagement disc  28  locks the spool  8  to the spline hub  15  so that the spool  8 , the keyed engagement disc  28 , and the spline hub  15  may rotate together in a clockwise or counter clockwise direction. The spool  8  may be enclosed within a reel body  3 . The device  17  is engaged so that the preset amount of drag may be applied to the spool  8 , gradually or instantaneously. The aforementioned drag is adjusted to a preset value by turning the drag preset knob  1  clockwise or counter clockwise into a threaded opening in a drag housing  2 , wherein the spring compressor  4  is pushed forward (i.e., in the direction  99 ). The force of the spring compressor  4  moving forward in the direction  99  compresses the compression spring(s)  5 . The compression spring(s)  5  is circular with a clearance hole in the center that fits over (i.e., encloses) the spline hub  15 . The compression spring(s)  5  applies a force in the direction  99  to the back of the surface  81  of the taper drag disc  7 . The front surface  82  of the taper drag disc  7  is used as a braking surface for the device  17  to engage. As the front surface  82  of the taper drag disc  7  is engaged by the device  17 , the taper drag disc  7  is forced backwards (opposite to direction  99 ) towards the compression spring(s)  5 . The friction between the device  17  and the front surface  82  of the taper drag disc  7  thus creates the preset amount of drag. The taper drag disc  7  is a part of the drag mechanism as described supra. The device  17  may be released from the drag mechanism so that the preset amount of drag is disabled and the spool  8  (i.e., as shown in FIG. 3) is free to spin, allowing for the free pulling of line from the fly fishing reel for casting. The device  17  may enable the preset drag after the preset drag is disabled. The device  17  and the drag mechanism may be separate components or as portions of a same component. A torsion spring  23  may be used to return the device  17  to a desired or predetermined position. A locking cap  32  may be used to lock the device  17  in a desired or predetermined position. A washer  36  comprising metal or plastic may be used between the trigger  17  and the reel body  3 . The device  17  may comprise a metallic alloy or metal such as, inter alia, stainless steel or aluminum. The spool  8 , drag housing  2 , and reel body  3  may each comprise a metallic alloy or metal such as, inter alia, aluminum. The taper drag disc  7  may comprise plastic such as, inter alia, Rulon® or Nylon®. The spring compressor  4 , compression spring(s)  5 , spool engagement shaft  9 , spline hub  15 , torsion spring  23 , engagement disc  28 , and locking cap  32  may each comprise a metallic alloy or metal such as, inter alia, stainless steel. The drag preset knob  1  may comprise, inter alia, plastic, metal, or a metallic alloy.

The device  17  is engaged so that the preset amount of drag may be applied to the reel  8 , gradually or instantaneously. The aforementioned drag is adjusted to a preset value by turning the drag preset knob  1  clockwise or counter clockwise into a threaded opening in a drag housing  2 , wherein the spring compressor  4  is pushed forward (i.e., in a direction  99 ). The force of the spring compressor  4  moving forward in the direction  99  compresses the compression spring(s)  5 . The compression spring(s)  5  is circular with a clearance hole in the center that fits over (i.e., encloses) the spline hub  15 . The compression spring(s)  5  applies a force to the taper disc backer  6  that is adhesively coupled to a back surface  81  of the taper drag disc  7 . A front surface  82  of the taper drag disc  7  is used as a braking surface for the device  17  to engage. As the front surface  82  of the taper drag disc  7  is engaged by the device  17 , the taper drag disc  7  is forced backwards (opposite to direction  99 ) towards the compression spring(s)  5 . The friction between the device  17  and the front surface  82  of the taper drag disc  7  thus creates the preset amount of drag. The taper drag disc  7  is part of the drag mechanism as described supra. The device  17  may be released from the drag mechanism so that the preset amount of drag is disabled and the spool  8  is free to spin, allowing for the free pulling of line from the fly fishing reel for casting. The device  17  may enable the preset drag after the preset drag is disabled. The device  17  and the drag mechanism may be separate components or as portions of a same component. The device  17  may comprise a metallic alloy or metal such as, inter alia, stainless steel or aluminum. The spool  8 , drag housing  2 , and reel body  3  may comprise a metallic alloy or metal such as, inter alia, aluminum. The taper drag disc  7  may comprise plastic such as, inter alia, Rulon ® or Nylon®. The bearing  12  may comprise metal such as, inter alia, stainless steel or plastic including, inter alia, Rulan®.
