ABSTRACT:
Apparatus is described which may be substituted for the vertical rule on a conventional drafting machine arrangement having a pair of rules set at right angles to one another. The apparatus includes a clamp for a transfer sheet which is movable in steps. Used with a dry transfer sheet with lines of letters on it, the interline spacing of which is an integral multiple of the stepped movement spacing of the apparatus, and fitted to a conventional drafting machine, the apparatus assists in applying accurate baseline legends to drawings using dry transfer rather than hand lettering.
