FORE:Standard gauging implements were introduced about the year 1840, by the celebrated Swiss engineer, John G. Bodmer, a [148]man who for many reasons deserves to be considered as the founder of machine tool manufacture. He not only employed gauges in his works to secure duplicate dimensions, but also invented and put in use many other reforms in manipulation; among these may be mentioned the decimal or metrical division of measures, a system of detail drawings classified by symbols, the mode of calculating wheels by diametric pitch, with many other things which characterise the best modern practice.The reciprocating cutting movement being but four inches or less, a crank is obviously the best means to produce this motion, and as the movement is transverse to the rack, which may be long and unwieldy, it is equally obvious that the cutting motion should be performed by the tools instead of the rack.
FORE:VII."Not yet," he said. "I am not going to throw this chance away. I came here to see Mr. Isidore, and I elected to wait. It was one of the best hour's work I ever did. When you leave here it will be for a gaol."
