1. Apparatus for engraving a planar workpiece carried by a workpiece support, in which scribing means engraves a miniature representation in a frustro-spherical plane of a two-dimensional pattern in response to two-dimensional planar movement of a stylus following said pattern, the combination comprising:

  • (a) means forming a pivotal support above said stylus, said support being freely rotatable in response to stylus movement;

    (b) means telescopingly connecting said stylus to said pivotal support so said support rotates in response to two-dimensional stylus movement about said pattern;

    (c) said scribing means fixed to said pivotal support above said stylus but below the center of rotation of said pivotal support, extending downwardly from said support and rotatably movable unitarily therewith in response to two-dimensional stylus movement about said pattern;

    (d) said means telescopingly connecting said stylus to said pivotal support including means for moving said workpiece, carried by said workpiece support, and said scribing means into and out of contact with one another independently of two-dimensional stylus movement over said pattern while said stylus maintains contact with said pattern, by rotating said workpiece support about a second pivot displaced from said center of rotation of said pivotal support.
