- This chronograph was probably made by Fauth & Co., in Washington, D.C. An important firm founded in 1874, Fauth boasted that their drum chronograph was “noiseless in its action, and the governor regulates the speed so perfectly that the second marks form a perfect straight line.” The recording drum was cylindrical, 14 inches long and 7.5 inches in diameter. It was powered by a falling weight and equipped with by a governor, and could run continuously for about 2.5 hours. New it cost $350. The United States Coast & Geodetic Survey recommended the form, and examples were found in many astronomical observatories. This example was bought for the Georgetown College Observatory in 1889.
