Eyelet threading aid
This invention relates to hook threading aids for fly fishing and needle threading aids for sewing. 
     BACKGROUND 
     Fly fishing enthusiasts know that the best time of day for fishing is at dawn or dusk. However, in the dim light conditions during these hours it is difficult to thread the fishing line (leader or tippet) material through the eyelets of small hooks to secure the fly. This is especially true for persons whose eyesight is impaired due to disease or injury. 
     The threading process is also hindered when excess head cement or fly tying materials obstruct the eyelet of the hook. 
     This same device may be used by sewing enthusiasts to thread needles where additional light is needed on the eyelet of the needle. 
     SUMMARY OF THE INVENTION 
     This invention is useful in several ways in solving the problems: clearing the hook eyelet, providing a light at the point of need, and providing a much larger loop to receive the fishing line. 
     The invention is an apparatus for threading an eyelet of any suitable instrument such as a needle, a fish hook and the like. The apparatus has two essential parts which are a lamp or lamp means, for example a pen light or pocket light such as may be purchased from the Industrial Safety and Security Company under the trademark &#34;Mity Light&#34;, Mag Instrument Inc., 1635 T South Sacramento Avenue, Ontario, California, under the trademark &#34;Maglite&#34;; and Flex-Lite Inc. division of Lukens Inc. 3515 East Kilgore Road, Kalamazoo, MI. 49001 under the trademark &#34;Flex-lite&#34;. G.T. Price Products Inc., Eveready Battery Co. Div. of Ralston Purina and Ray-O-Vac Corp. also make suitable hand-held lamp means. 
     The second element is an eyelet threading device carried by the lamp means in the ambit of the light, whereby the source of light illuminates the eyelet threading device and the vicinity of the eyelet of the needle, hook or other instrument to be threaded. In a presently preferred embodiment the lamp has means for directing a focused beam of light and the threading device is in the path of the focused beam. The threading device is a resiliently deformable loop coming toward a point at its leading edge, preferably made of spring steel but which may also be made of plastic. A translucent covering or lens, which may be a clear plastic, and preferably solid, covers the source of light, e.g. an incandescent bulb and the loop has a base for attachment to the lens, preferably being embedded in a solid lens. 
    
    
     BRIEF DESCRIPTION OF THE DRAWINGS 
     Turning now to the drawings in which a presently preferred embodiment of the invention is illustrated: 
     FIG. 1 is a perspective view of the apparatus; 
     FIG. 2 is a partial view of the apparatus of FIG. 1 partially broken away; 
     FIG. 3 is an isolated view of the covering for the light source; and 
     FIGS. 4A-4D show the method of utilizing the invention to thread the eyelet of a small hook or needle. 
    
    
     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     There is a source of light, here a bulb, in a small flashlight (e.g., penlight) energized by a battery in a conventional way. 
     The usually hollow lens of the flashlight 1 is preferred to be made as a solid, molded or machined lens 2 made of clear plastic or acrylic material. The new solid lens 2 will incorporate a spring steel threading loop 4 in casting as part of the lens. The loop 4 lies in the path of the beam. 
     The loop 4 may alternatively be a strong, resilient plastic. 
     The loop comes toward a point at its leading edge 5. It should be of a gauge sized to allow the clearing of the eyelet 6 of the hook 7 of most debris, but not so large that it cannot fit into the eyelet of a small hook (for example, a #22). 
     A means for focusing and directing the beam is parabolic reflector 10, usually a standard part of a pen light. 
     Now referring to FIGS. 4A-4D, in the method of use, the flashlight 1 is turned on, the threading loop is inserted in the eyelet 6 of the hook 7 or needle 8, and the fishing line or sewing thread (not shown) is passed through the loop 4. When the loop 4 is withdrawn, the fishing line or thread will be pulled with it through the eyelet and the eyelet thus threaded. The knot can then be tied in the traditional manner. 
     Whereas a presently preferred embodiment of the invention has been described and illustrated, persons ordinarily skilled in the art will understand that various equivalent embodiments may be employed, all of which are embraced in the appended claims.
