"Cross Depth Gauge Jacques Langlois, Circa 1718/29"
Very rare depth gauge in the shape of a cross and brass by Jean-Jacques Langlois, circa 1700/1710 Very rare and simple measuring instrument bearing the rare French signature of Jean-Jacques Langlois. He was an apprentice of Butterfield. 2300 euros The vertical brass bar carries a ladder divided into inches and lines; the horizontal brass bar is equipped with a sliding friction system. In use, the horizontal arms of the gauge are placed on the ends of the opening of a container or cavity to be measured. The vertical sliding bar is then lowered inside the cavity until it touches the bottom. This gives a precise measurement of the depth. The gauge is divided into 54 lines, evening 4 inches and a half, and measures 122mm in height. Rare and early brass measuring instrument used in physics, chemistry and more generally in engineering. See the model developed later by the Duke of Chaulnes and preserved in Florence at the Galileo Museum:
