Young's speed indicator, with open dial, 1881, on mahogany stand
This form of speed of revolution indicator was patented in 1881 by Mr. D. Young. It consists of a small centrifugal governor, loaded by a helical spring and enclosed in a case. When the spring is compressed owing to the centrifugal tendency of the governor balls, the speed of rotation is indicated in rev. per min. by a finger connected with the spring by levers and toothed gearing, by which it is moved over a suitably graduated dial.
