Abstract

655,766. Gauging surface roughness. SPAHR, E., and MULLER, K. March 24, 1948, No. 8659. Convention date, April 11, 1947. [Class 106 (ii)] In a surface roughness gauge having a housing with abutment faces which bear against the surface to be tested and a movable feeler contacting the test surface and operating a recording device, the feeler is carried by a slide movable along a rectilinear guideway in the housing parallel to the abutment faces. The housing 1, Fig. 1, is formed with plane surfaces 18 (or 19 for use with narrower test-surfaces) by which it rests on the test-surface 7 and with the guideway 2 for the slide 3, which is traversed along the guideway by rotating a threaded shaft 4 by means of a hand wheel 14 or, through gearing, by a reversible spring-operated or electric motor 15. Pivoted on the slide is a lever 5, carrying an adjustable feeler screw 6 which projects through a slot in the casing 1. One arm of a horizontally arranged lever 8 is held against the lever 5 by a spring (not shown). An arm, formed by a longitudinally adjustable screw 10, of a lever 9 is held in contact with the second arm of the lever 8 by a further spring (not shown) and transmits the movement to a counterbalanced stylus 12 which makes an enlarged record of the surface profile on a stationary paper-strip 13. For testing the surface of a cylinder 27, Fig. 5, a head 20, having an under surface of inverted V-shaped cross-section and a longitudinal slot for the feeler 6, is mounted on the faces 19 of the casing 1.
