Abstract

1,192,513. Measuring scales: Indicating apparatus. FEINMESS DRESDEN VEB. May 2, 1968, No. 20893/68. Headings G1J and G1M. Elements 1 and 2 adapted to make up a scale are provided with interfitting ends each cutting at least one graduation 5 so that as the elements are fitted together to form a complete scale the part graduation 5 on one element may be easily vertically aligned with the part graduation 5 on the other element. The gap 3 between the elements may be joggled instead of straight and cut several graduations, Fig. 1-4 (not shown).
