  • Patent number: 5167088
    Abstract: The activator is cut and shaped from sheet plastic and installed on the leader just in front of the lure attached to the leader. Motion of the lure and activator through water causes the activator to oscillate angularly, generating alternating lateral forces on the leader and thereby activating the lure. In a preferred embodiment the planform of the activator is circular with a hole at its center and the activator is creased radially from the hole to its perimeter so that the portions of the activator adjoining the crease are at a shallow angle to each other. Creasing, as different from bending or forming, stretches the material at the open side of the angle at the crease beyond its elastic limit and allows it to take a set. The stretched material is under compression when the part is finished, the compression holding the adjoining portions at an angle. This technique virtually eliminates the tendency of the plastic to resume its preformed shape and allows manual adjustment of the angle.

  • Patent number: 5098137
    Abstract: The device facilitates tying a variety of knots similar to the commonly termed nail or tube knot. It is flat and generally rectangular with a hole at one end and a fork at the other. The fork is two-tined, narrower than the remainder of the device and centered widthwise on it. The profile change from full width to fork width forms angled shoulders at the base of the tines. The depth of the slot between the tines is greater than the distance from the tips of the tines to the junctures of the shoulders and the tines by an amount at least equal to the width of the slot between the tines. There is a second slot called the side slot, normal to one of the long edges of the device, with a depth in the range of 1/4 to 1/2 the width of the device, 1/3 being preferred. In a preferred embodiment the device is 3/8 of an inch wide, 0.060 of an inch thick and 2 inches long with the fork occupying 1/4 of the length.

  • Patent number: 5020833
    Abstract: The accessory tool for anglers comprises two class 1 levers and a fulcrum between them. The levers are flat and rectangular, approximately twice as long as they are wide. They are pivoted on opposite sides of the fulcrum by stubs extending from the fulcrum through mating holes in the levers and held in place by an elastic band which also serves as a resilient element which biases one set of ends of the levers together. These ends are of uneven length so that one end rests against the other to form a pincer for holding ends of lines, leaders or the like. There are two hooks, one on each of these ends, which form an opening when the apparatus is at rest and the pincer closed. When the other ends are pressed together the tips of the hooks part, forming a gap in the opening and the pincer is opened.
