  • Patent number: 6941628
    Abstract: The invention comprises tools for forming beads on one or more filaments using a malleable material for the bead. The tools exert bead-forming forces radially inward toward the filament and axially along the filament toward the center of the bead. The tools comprise pliers with jaws which meet flush with each other over at least a portion of the jaw face. Aligned cavities are formed in each jaw face wherein each cavity's dimension across the jaw face is less than the width of the jaw face. Grooves, aligned generally transverse to the width of the jaw face provide a filament-receiving channel between the cavity and the edge of the jaw face. Malleable material encompassing the filament is aligned between the aligned cavities and the jaws are closed. The radial force of the cavity walls on the malleable material deforms the malleable material radially and the walls of the cavity exert a force axially to form a bead.

  • Patent number: 5934342
    Abstract: A hand tool combines jaws for gripping a wire with a spool for winding the wire so as to increase longitudinal tension in the wire prior to completing a splice. A method of the present invention for tensioning and splicing two wires includes the step of winding a wire around a spool while maintaining a grip on the wire between manually operated jaws until sufficient tension is established in the wires being joined. The hand tool and method provide splices with greater tension and lower risk of personal injury than possible with conventional tools and methods and are particularly appropriate for repairing electric and barbed wire fencing as used in ranching operations.

  • Patent number: 4392494
    Abstract: This patent describes a new orthodontic instrument to be used for tying or twisting the ligature wires used to hold the arch wire to the bracket. It also explains the method of use which consists of: twisting the wires, after the ligature wire has been placed on the bracket; tucking the twisted end out of the way; and then breaking the end at the tip of the instrument. The instrument replaces three instruments normally used, by improvements in jaw design to facilitate grasping and centering the wires for spinning, balancing the instrument by general symmetry, and the addition of an extension handle to allow rapid spinning, and tucking of the wire ends as they are broken in a controlled manner, and at a specific place. The instrument thus simplifies, speeds and further improves the application of ligature wires.
