1895 'Wire Fly Wheel.
Among the most recent and novel applications of wire, perhaps none has greater interest to the world than that presented by the new wire fly wheel lately erected at the Mannesmann Tube Company's Works, Germany. Heavy fly wheels driven at high velocities obviously present dangers of breaking asunder from the great centrifugal force developed. The wheel at the factory mentioned consists of a cast iron hub or boss, to which two steel plate discs or checks, about 20 feet in diameter. are bolted. The peripheral space between the disc, is filled in with some 70 tons of No. 5 steel wire, completely wound round the hub, and the tensile resistance thus obtained is far superior to any casting. This huge fly wheel is driven at a speed of 240 revolutions per minute, or a peripheral velocity of about 2.8 miles per minute, which is over twice times the average steed of any express train in the world. The length of wire upon such a constructed fly wheel would be about 250 miles.'
