BACKGROUND OF THE INVENTION 
     Numerous fishing lures have been taught which provide the user with the ability to impart an erratic or vibrant lure path. One such device is disclosed by Barnhart in U.S. Pat. No. 4,492,054. However, in order to control the lateral motion of the lure, fishermen have been required to bend the eye hook to the left or to the right to make the lure swim to the left or to the right, respectively, as it is retrieved. This is commonly referred to as tuning the lure. The process often involves over-bending the eye with pliars and then correcting the bend by trial and error until a desired lure path is achieved. Excessive manipulation of the eye hook weakens the metal material. Peterson in U.S. Pat. No. 3,874,109 teaches an alternative method of tuning a lure. His device includes a forward beak portion which is bent to regulate the path of the lure. However, this method is subject to the shortcomings of the method discussed above. That is, the lure must be tuned by trial and error and excessive bending of the beak portion eventually weakens it. 
     An important object of the invention, therefore, is the provision of a lure which can be set by the user to follow a controlled path upon retrieval. 
     Another object of the present invention is the provision of a lure which is designed to be set by the user to swim to the left or to the right without requiring the deformation of any part of the lure. 
     A further object of the present invention is the provision of a tuning mechanism for a fishing lure which may be set precisely to follow a predictable path, not requiring trial and error to achieve that path. 
     SUMMARY OF THE INVENTION 
     It has been found that a fishing lure may be provided with a tuning mechanism housed in a receptacle formed by a recess in the spoon and a downwardly protruding plate having a screw carried in the plate perpendicular to the spoon, a head carried by the screw on each of the two opposed ends, an eye hook carried by a center portion of the screw extending upwardly from the screw, means for moving the eye hook laterally within the receptacle, means for restraining rotational movement of the eye hook, so that the eye hook may be positioned laterally with respect to the spoon and the lure body.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     A fishing lure having a body, hooks attached to the body, and a forwardly extending horizontal spoon A is provided with a plate B extending vertically downwardly from a central portion of the spoon and a screw C carried in the plate beneath and perpendicular to the spoon. A receptacle D is formed by a transverse recess in the horizontal spoon, extending vertically downwardly into the plate about the screw. A head E may be carried by the screw on each of two opposed ends so that adjustment of the screw at either head causes the screw to move laterally within the plate. An eye hook F, carried by a center portion of the screw, extends upwardly in the receptacle through the plate and the spoon and protrudes upwardly from the screw. The eye hook moves laterally within the receptacle responsive to the lateral movement of the screw but is restrained from fully rotating responsive to the helical movement of the screw. Thus, the path traveled by the lure as it is retrieved may be controlled responsive to the lateral disposition of the eye hook. 
     Referring to the drawings, a fishing lure 10 is illustrated as having a body 12 with hooks 14 attached thereto. A spoon 16 protrudes forwardly from the lure with a plate 18 extending downwardly from the spoon. A transverse receptacle 20 is defined through a middle portion of the spoon down into the plate 18. Screw C is carried by outer walls 22 and 24 of the plate 18 with a center portion 26 of the screw disposed in receptacle 20. FIG. 6 best illustrates opposed heads 27 and 29 of screw C which are substantially disposed in side walls 22 and 24 of the plate 18 as shown in FIG. 4. Center portion 26 includes groove 28 which carries eye hook F as shown in FIGS. 4 and 5. A base portion 30 of eye hook F is anchored in plate 18 as shown at 32. 
     Plate 18 and head 27 include indicia 34 and 36 as shown in FIG. 3. Adjustment of screw C at head 27 in accordance with indicia 34 indicates the direction and degree of lateral movement of the screw. As eye hook F is carried in groove 28 of the screw, adjustments made at head 27 in accordance with indicia 34 also determine the direction and degree of the lateral movement of the eye hook. That is, a sufficiently snug fit of eye hook F in groove 28 insures that the eye hook moves laterally with the screw. However, that fit must be sufficiently loose to prevent eye hook F from rotating responsive to the helical movement of screw C. Such rotational movement of the eye hook about a center axis of screw C is additionally prevented because base portion 30 is anchored in plate 18 as shown at 32 and inner walls 36 and 38 of receptacle 20 as abutments. Preferably, the projection of the eye hook above the center of the screw should be as small as possible to avoid possible accidental bending of the eye hook. 
     Thus, adjustments at either head of screw C allow the user to laterally displace the eye hook from the center of the lure body. Although not illustrated, it is to be understood that such a receptacle and screw combination could be adapted to a lure not having a spoon and plate but having the eye hook attached to the body of the lure. That is, the main object of the invention is the provision of means for easily and predictably moving the eye hook off center. It has been found that the path of the lure is controllable responsive to the lateral disposition of the eye hook. 
     It is thus seen that this invention provides a novel lure structure and particularly provides an improvement by allowing the user to predictably set the lateral disposition of the eye hook relative to the lure without risk of eventual material wear. As many variations will become apparent from a reading of the foregoing descriptions such variations are embodied within the spirit and scope of the following appended claims.
A tuning mechanism is provided for a fishing lure allowing for predictable control of the path traveled by the lure permitting the user to cause the lure to swim to the left or the right as it is retrieved.
