Abstract

197,534. Keeping, A. C., and Slade, G. H. May 9, 1922. Linear-dimension gauges. -Each arm a, a<1> of a pair of callipers has an extension beyond the pivot pin B and carries an arcuate plate a<2>, a<3> the inside surfaces of these plates having scales D which are covered and protected when the callipers are closed. The scales may be in different units so that simultaneous readings in two units may be taken.
