  • Pincer-gun for electrically heating metal hinges of thermoplastic eyeglass frames
    Patent number: 4553021
    Abstract: A manually operated pincer-gun utilizing electric current for heating metal hinges of a thermoplastic eyeglass frame during a repair operation includes a pair of electrically insulative hand grips, each operatively connected to an arm having an electrically conductive extremity. The hand grips are pivotally connected together such that the hand grips and the respective arms and extremities are movable toward each other. An electrically conductive heating tip and an electrically conductive picking-up tip are provided on the extremity of each arm and the secondary of a step-down transformer controlled by a pedal switch is connected to the respective extremities to supply heating current to the heating and picking-up tips. The heating tips form a pair of pins extending substantially parallel to each other to be able to be placed on the base of the hinge to apply electric heating current thereto to soften the eyeglass frame around the hinge for insertion or extraction of the hinge.
