1. A contour transfer device comprising first and second elongated main bars;

  • said bars disposed in adjacent parallel relation to each other;

    each of said bars having a facing side and an outer side;

    said facing side being adjacent to each other;

    each of said main bars having a plurality of finger receiving holes extending laterally through each of said bars and said holes in each bar disposed in a substantially straight row;

    the finger receiving holes of said first bar being axially aligned with said holes in said second bar;

    elongated feeler and contour transfer fingers extending through said aligned finger receiving holes of both of said bars;

    each bar, in its facing side, having a frusto-conical recess surrounding each of said finger receiving holes therein;

    said frusto-conical recess diverging toward said facing side;

    resilient O-rings disposed in said frusto-conical recesses;

    each of said rings closely surrounding one of said feeler and contour transfer fingers;

    the cross sectional diameter of each O-ring being sufficient to engage and nest in said frusto-conical recesses and to compressively hold said main bars in slightly spaced apart relation to each other at facing sides;

    each of said fingers having a peripheral portion; and

    clamp bolts disposed adjustably to force said main bars together to thereby reduce the spacing between said facing sides of said bars and to thereby compress said resilient O-rings in said Frusto-conical recesses and to thereby cause compressive frictional engagement of each O-ring about the said peripheral portions of a respective one of said feeler and contour transfer fingers whereby said fingers, when longitudinally adjusted in a direction laterally of said bars, will hold an adjusted position with substantial resistence to change.
