  • Patent number: 4353728
    Abstract: A tong supporting carriage is provided with an elongated tong support member having elongated slots with low friction bearing means for supporting in free sliding and rotating relation a vertical rod having a clevis attached to its lower end. A lever arm having tongs suspended freely on tong suspension points on opposite sides of said clevis is attached to the clevis intermediate its ends. When two pairs of tongs are used to grip a glass sheet to be bent about a vertical axis of bending, the tong suspension points move with the tongs gripping localized portions of the upper edge of the glass sheet and pivot the vertical rod, which slides longitudinally toward the other vertical rod as the distance between points subtended by the vertical rods on the glass sheet decreases as the glass sheet bends about a vertical axis. Kinking of the glass in the vicinity of the tong gripping points is thus minimized.
