Abstract
Device for attachment to gauging instruments such as optical measuring apparatus, which measure dimensional parameters of articles by scanning the surface or main profile of the article with a light beam as from a laser, the device employing a leaf spring assembly for bearing against and conforming to a portion of the surface of the article; the leaf spring assembly thereby forming a substitute profile over the main profile of the article or of a transparent article, and suppressing any surface anomalies projecting from the article surface, thus providing a reference surface which may be measured by such gauging instruments as representative of the dimensional parameter of the main profile of the article.
Claims7
Device for use with and for enabling gauging instruments, which measure the thickness, diameter, circumference or other dimensional parameter of articles by means impinging or scanning the surface of the article, to make more accurate measurements of transparent articles or of the main profile of an article having surface anomalies projecting from the main profile, said device comprising:
- a support means;
- and
- flexible means connected to said support means for bearing against and conforming to a portion of the surface of the article to be measured and thereby form a substitute profile on the main profile of the article, said substitute profile suppressing any said surface anomalies and providing a reference surface to be measured by said gauging instruments as representative of the article main profile.
