Abstract
Abstract A clamp is disclosed comprising a frame having two rigid supports spaced mutually apart along an axis and a screw threadedly mounted to one of the supports for axial movement along the axis. A first pressure contact member is pivotably mounted to an end of the screw between the two frame supports. A yoke is pivotably mounted to the other of the two supports for rotary movement about the axis with two yoke arms straddling the axis. A second pressure contact member is mounted to each of the two yoke arms for rotary movement between the two frame supports aside the frame axis.
