  • Patent number: 6793208
    Abstract: A tool system for inserting temple screws in eyeglass frames includes first and second scissor arms, with each scissor arm having proximal and distal ends, the arms pivotally connected so that the ends can be moved towards and away from one another when the arms are pivotally moved using finger-receiving devices at the distal ends of the scissor arms. A clamp locking mechanism is an extended ratchet device for providing stepwise engagement of the first and second scissor arms in a position where the finger receiving devices are moved closer together and prevented from moving further apart. Clamping and gripping surfaces at the proximal ends of the arms grip the spring hinge eyeglass frames, with an elongated projection extending away from the clamping surface on one arm to engage the eyeglass temples to temporarily secure the spring hinge in a state of extension.
