Abstract

548,317. Drawing instruments. CRAWLEY, J. A. April 19, 1941, No. 5079. [Class 97 (iii)] The points E of dividers used for measuring lengths of test pieces are bent at right-angles to the plane of the legs so that when they are sharpened the effective lengths of the legs are unchanged. A dial gauge C is pivoted to one leg and its plunger part F pivoted to the other leg, and these parts may be removable to enable them to fit another similar instrument.
