Silencer of anti-reverse fishing reel
BACKGROUND OF THE INVENTION 
     Whenever winding the fishing line of a fishing reel a conventional ratchet R and catch C arrangement performs an anti-reverse function as FIG. 1 shows so as to prevent counter rotation in direction R1. The catch C is formed with a narrow recess C1 for the insertion of a spring plate S therein. While normally rotating the ratchet C in direction R2, the clicking sound produced when the ratchet strikes the catch will be transmitted into the water to scare the fish, adversely affecting the fishing. As some fishermen enjoy the silence of nature during fishing, the clicking sound created by the prior art reel ratchet may possibly bother the fishermen. 
     The present inventors have noted such phenomena and invented the present silencer for an anti-reverse fishing reel. 
     SUMMARY OF THE INVENTION 
     The object of the present invention is to provide a rubbing block adhered on a catch and a widely opened recess on the catch for the substantial disengagement of the ratchet from the catch during normal rotation of the fishing reel so as to silence the clicking of the reel.

     DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS 
     As shown in FIGS. 2, 3 and 4, the present invention comprises a rubbing block 2a adhered onto a catch 2 which performs an anti-reverse function for the ratchet 14. Ratchet 14 is formed beneath a driving gear 13 and rotated by a shaft 12 and a handle 11. The catch 2 comprises a catch shaft 21 pivotedly formed on reel 1, an inner anti-reverse hook 22 and an outer limiting hook 24. Hooks 22 and 24 form a buffer recess (a wide opening 23, therebetween. 
     Rubbing block 2a frictionally contacts a flat surface 13a of driving gear 13 and is formed sharply on inner anti-reverse hook 22 of catch 2. The block 2a may be made from any material having a good frictional surface or from plastic foams such as polyurethane (PU) foam or ethylene vinyl-acetate (EVA) foam. 
     A head portion 25a of a spring plate 25 is freely inserted into buffer. Spring plate 25 is lowerly formed with a hook portion 25b fixed on a sliding clutch 26. The hook portion 25b is movably engaged with either of the three grooves (a first groove 15, a second groove 16 and a third groove 17) formed on the casing wall of the reel. 
     When rotating the fishing reel 1 in direction R1 (as shown in FIG. 4) the inner anti-reverse hook 22 of catch compulsively interferes with ratchet 14 to prevent counter rotation of the reel 1 in direction R1. When normally rotating reel 1 in direction R2 for winding the fishing line, driving gear 13 will move catch 2 by frictionally carrying rubbing block 2a on catch 2 in direction R3 along catch shaft 21 to a dotted-line position (as is shown in FIG. 4) to release the outside the ratchet teeth so as to have a silencing effect (as no clicking will be created between ratchet 14 and catch 2). Buffer recess 23 provides a buffer space for stopping the movement of anti-reverse hook 22 on the head portion 25a of spring plate 25, thus separating from the ratchet teeth. 
     When re-rotating reel in direction R1, catch 2 with rubbing block 2a will be frictionally carried to a locking position (direction R4), depicted as full line in FIG. 4, to have a corresponding anti-reverse effect. 
     Hook portion 25b of spring plate 25 is movably engaged with either of the three grooves formed on the casing wall of reel 1 (a first groove 15, a second groove 16 and a third groove 17). As shown in FIG. 4, hook portion 25b is engaged with second groove 16 so as to allow the head portion 25a of spring plate 25 limiting the position of the outer hook 24 of the catch to cause inner hook 22 to lock with ratchet 14 for preventing the ratchet from rotating in a reverse direction. 
     When the hook portion 25b of spring plate 25 is engaged with third groove 17, as is shown in FIG. 5, the head portion 25a pushes inner hook 22 of catch 2 to lock ratchet 14 for preventing counter rotation R1. When normally rotating ratchet 14 in direction R2, a clicking sound will occur as the ratchet impacts catch 2 which is backed by spring plate 25. The clicking sound is used to indicate the rotation of reel 1 to someone used to the occurrence of the clicking sound during winding of the fishing line. 
     In FIG. 6, hook portion 25b is shown engaged with first groove 15 so that spring plate 25 will retract catch 2 to release rubbing block 2a from the flat surface 13a of driving gear 13 to a position beyond the sloping surface 13b for free silent rotation of the ratchet. 
     Another preferred embodiment of the present invention is shown in FIGS. 7 and 8, wherein the aforementioned sliding clutch 26 is substituted with a swing clutch 26a. The clutch 26a is connected with a clutch arm 26c by a pivot 26b. A spring wire 25c is disposed within recess 23 of catch 2 at its upper end 25d and is fixed on clutch arm 2 by its lower end 25e. When clutch arm 26c is engaged with the second recess 16 (as shown in FIG. 7), ratchet 14 will be silently rotated in direction R2 and will not be counter rotated in direction R1. This is similar to the mode of operation shown in FIG. 4. When clutch arm 26c is engaged with the third groove 17, ratchet 14 will be normally rotated with clicking sound but in an anti-reverse mode as shown in FIG. 9, which is similar to that shown in FIG. 5. If clutch arm 26c is engaged with the first groove 15 (as shown in FIG. 10) ratchet 14 will be rotated free and silently (as similar to that shown in FIG. 6.
