Abstract
23,238. White & Poppe, and Buswell, E. Oct. 31. Scales.-A measuring-scale is made cylindrical in shape and is divided longitudinally into fractions of an inch say twentieths, B; these divisions are connected by a helical cut D with a pitch of onetwentieth of an inch. The cylinder is divided circumferentially by a number of lines E, drawn parallel to the axis, which intersect the helix D. If there are fifty of these lines E, then starting from the line F at the zero line C, thousandths of an inch may be marked off with dividers. To facilitate reading, a slide G may be mounted over the scale ; this slide, which is rotated by the milled head J, engages a screw-thread H of the same pitch as the helix D and is divided as shown into lengths of an inch adapted when in the normal position to coincide with similar divisions on the zero line C. The scale may be built up of a number of inch units K adapted to telescope into one another so that the scale may be used with a surface gauge.
