Abstract

515,221. Magnetic tests. LUMB, C. F. May 26, 1938, No. 15716. [Class 37] In a gauge which measures the thickness of a non-magnetic coating on a magnetic metal, a permanent magnet deflects a vane g pivoted by means of spindle d biassed by spring hand associated with pointer e and scale f. The magnet has pole projections c to establish point contact with the coated surface b. Scale f is rotatable and is graduated in a scale of thickness.
