A pair of flanged telescoping covers houses a main spring comprising two opposed Belleville discs, which provide the elastically deformable metal that is squeezed when the gage is placed between the track and an idler wheel. Cam mechanism occupies a central cavity provided by both covers, wherein a pin held against rotation by one cover engages slots in a cup movable in the other cover against a helical spring. The cup carries a pointer which moves across a scale. Author
