## Background
CROSS REFERENCE TO RELATED APPLICATION
This application claims the benefit of U.S. Application Ser. No. 60/559,706 filed Apr. 6, 2004.


FIELD OF THE INVENTION
The invention relates to fishing jig lures having fish hooks joined to head and methods of making fishing jig lures.
BACKGROUND OF THE INVENTION
A conventional fishing jig head has a fish hook joined to a lead head. The lead head surrounds the shank of the fish hook adjacent the eye. The head is coated with colored paint. Jigs are bottom fish lures which snag on rocks, water plants and roots. They detach from the fish line and settle on the bottom of the lake or river beds. Lead heads that remain in the lake and river beds are not environmentally compatible with wild water birds, such as ducks, geese and loons. A number of states have prohibited use of lead fishing weights and lures.
Examples of fishing lures are disclosed in the following U.S. patents.
Comisky in U.S. Pat. No. 5,245,783 discloses a fishing jig having a glass head connected to the shank of a fish hook. The head has a spherical shape with a longitudinal groove accommodating a section of the shank of the fish hook. A glue-like material including adhesive resins located in the groove secure the fish hook to the head.
Hirahara et al in U.S. Pat. No. 6,145,239 disclose a soft bait fishing lure having glass materials mixed in a lower section of the body of the lure. The glass materials reflect light.
Ellig in U.S. Pat. No. 6,318,016 describes and shows a luminous fishing lure. The lure has elongated fiber optics located in grooves in opposite sides of the body of the lure.
The fiber optics are exposed to receive energy from material or artificial light sources. The forward ends of the fibers form a bulbous lens that focus the light to simulate eyes of a fish.
SUMMARY OF THE INVENTION
The fishing jig lure of the invention has a glass body joined to the shank or shaft of a fish hook with a plastic material having phosphorescent particulates that emit light after being stimulated by radiation. The glass body has a convex curved shape with a longitudinal top groove accommodating the shank of the fish hook. The plastic material is an epoxy adhesive that bonds to the glass and secures the fish hook to the glass body. The phosphorescent particulates are stimulated by light sources including sunlight, moonlight, flashlights, power flashers and ultraviolet light. The convex curved shape of the glass body magnifies the light from the phosphorescent particulates. The fishing jig lure is environmentally compatible as it does not have any lead or paint.

DESCRIPTION OF PREFERRED EMBODIMENTS OF FISHING JIG LURE
The fishing jig lure indicated at 100 in FIG. 1 to 8 has a metal fish hook 101 comprising a linear longitudinal shank or shaft 102 joined at one end to an eye 103 and the opposite end to a forwardly turned hook 104. A round glass body 106 is secured to shank 102 adjacent eye 103. Eye 103 projects forwardly from the front of body 106. As seen in FIG. 3 the end of hook 104 is located in a plane above the horizontal plane of the top of body 106. An insert 107 of plastic material located in a longitudinal groove 108 in the top of body 106 is bonded to the glass of body 106 and retains shank 102 along the base or bottom 109 of groove 108. A semi-hemispherical projection 111 is joined to the bottom of body 106. Projection 111 can be a part of body 106. A color spot or circle is located on the center of projection 111.
Body 106 is a one-piece glass member. The glass is a mixture of silicon dioxide, sodium and calcium carbonate. A boron silicate glass is an example of the material of the glass member. The glass member can be transparent, clear, translucent, or colored. Groove 108 has a generally V-shape with base 109 along the longitudinal center of body 106.
Insert 107 is a two-part epoxy resin that bonds by polymerization to glass body 106 and shank 102 of fish hook 101. Color material can be added to the epoxy resin. Examples of colors are red, orange, blue, pink, gold, green, purple and chartreuse. Other colors can be included in the epoxy resin. The phosphorescent particulates are powder mineral zinc sulfide known as sphalerite or zincblende that are mixed with the epoxy resin. Zinc sulfide gives off light after being stimulated by radiation. The zinc sulfide particulates are phosphorescent as they have molecules that are excited by light to a higher electronic state and then undergo a radiation transition to a state of different multiplicity from which it decays to the ground state. The emitted light is normally of longer wavelength than the exciting light because vibrational energy has been dissipated. The epoxy resin and phosphorescent particulates do not include lead or other environmentally damaging materials.
The fishing jig lure 100 is made by heating the glass, such as a glass rod, to a semi-liquid state. Bodies of hot glass are deposited on a surface. A wedge shaped tool is used to make groove 108 in the top of the glass body 106. The glass body 106 is allowed to cool. The epoxy resin mixture containing the phosphorescent particulates is placed into the groove. The epoxy resin can be clear or colored. The shank 102 of the fish hook 101 is then inserted into the epoxy resin mixture and moved down to locate the shank 102 against the base 109 of groove 108. The epoxy resin is then allowed to cure to a hard state. The hard epoxy resin retains the fish hook 101 in a fixed position on the glass body.
In use the glass body 106 and epoxy resin insert 107 containing phosphorescent particulates is subjected to a light source, such as sunlight, a flash light, or power flasher. The light charges the phosphorescent particulates to a state where they emit light or glow. The effective glow has a time duration between 15 to 60 minutes. The color of the epoxy resin or color of the glass body determines the color of the light and duration of the glow. The fishing jig lure is in condition as a fish lure with or without live bait.
