Today’s digital caliper substitutes a magnetic scale on the beam. In addition to outside measurements they also measure inside, depth and height. This was the first multiple-measurement caliper. This caliper works with a rack gear on the beam and a pinion gear under the dial. The vernier caliper was in heavy use until around 1960, when the dial caliper was invented by the Germans. Its beefy beam and micro adjuster made this a really great measurement tool. Machinists loved the pocket vernier caliper-which is really just a precise scale. Three years later, Brown took a partner, Lucian Sharpe, to handle the business, which was renamed J. He called his invention “Pocket Vernier Caliper.” He may have based his device on a special-use caliper made by a French artillery factory in 1840. He decided to make a device that used the vernier scale to measure the size of clock parts. In 1850, Joseph Brown was trying to manufacture precision clocks. I’m going to skip over Pierre Vernier, who invented a precise scale. Obviously these measurements were flawed because no two arms or feet are exactly the same length. Noah measured using his arm (cubit) and the Greeks and Romans used their feet to conquer and measure the world. Measurements have been used to define and attempt to control the stuff we make throughout recorded history.
