Description
Mason said in his patent: "it will be readily seen that the machine is simple in design, economical in all its parts and arrangements, and that I cut or thread screws with less machinery and intricate or complicated movements than has been done heretofore; and, furthermore, that the severe strain and resultant wear and tear which other machines for like purposes are incessantly subjected to is avoided, and not experienced by my mechanism, even when run at comparatively high velocity."
