Machines for testing surface smoothness
Practical recording machine that would register surface smoothness over long distances with speed, accuracy and economy; device of this nature called "profilometer"; two other instruments, " vialog" and "roughometer," also have been developed for measuring pavement smoothness; instrument, called " bumpometer."
