The mill itself, as regards the roll, is much the same as those of other firms; but instead of an engine with a heavy fly-wheel, always working in one direction, and connected to the rolls by double clutch and gearing, the work is done by a pair of horizontal reversing engines, in connection with which there is a very simple, and at the same time extremely effectual, system of hydraulic reversing.
When it is out of the circuit, the next second, it is not a magnet, and it lets the clapper go. The clapper, oscillating to and fro, imparts a rotatory motion to a fly-wheel, which transmits it to the drivers on the rails. Such are our motors. They are no novelty, for trial has proved them practicable.
Here, too, was raw material organized: a fly-wheel, large enough to keep the knobbiest of asteroids revolving without a wabble; a cross-head, cross-tail, and piston-rod, to help a great sea-going steamer breast the waves; a light walking-beam, to whirl the paddles of a fast boat on the river; and other members of machines, only asking to be put together and vivified by steam and they would go at their work with a will.
A. Multiply the centrifugal force in terms of the weight of the body by the diameter of the circle in feet, and multiply the square root of the product by 4.01; the result will be the velocity of the body in feet per second. Q. Will you illustrate this by finding the velocity at which the cast iron rim of a fly-wheel 10 feet in diameter would burst asunder by its centrifugal force?
Because the Austrian Government, like the German and Italian Governments, know, what our recent Governments have never known, that Great Britain has for two or three centuries been the balance weight or fly-wheel of the European machine, by reason of the prescience with which her Navy was handled.
Let me illustrate this by a comparison between the earth rotating on its axis and the fly-wheel of an engine: The fly wheel is a sort of reservoir, into which the engine pours its power at each stroke of the piston. The various machines in the mill merely draw off the power from the store accumulated in the fly-wheel.
This particular "trusty" could no more understand Cowperwood than could a fly the motions of a fly-wheel; but with the cocky superiority of the underling of the world he did not hesitate to think that he could. A crook was a crook to him Cowperwood no less than the shabbiest pickpocket. His one feeling was that he would like to demean him, to pull him down to his own level.
Sincerity and justice, and resolution that indispensable fly-wheel of virtuous habit are found in his table of virtues; but all his moral precepts seem to be based on observation and experience of life, and to express his convictions concerning what is profitable, prudent, and on the whole satisfactory in the life that now is.
The engine was provided with a single cylinder six inches in diameter, with a fly-wheel working at one side to carry the crank over the dead points. Jonathan Foster described it to the author in 1854, as “a strange machine, with lots of pumps, cog-wheels, and plugs, requiring constant attention while at work.” The weight of the whole was about six tons.
Between the poles of the galvanometer was stretched a slender thread of fused quartz plated with silver. It was the finest thread I could imagine, only a thousandth of a millimeter in diameter, far too tenuous to be seen. Three feet further away was a camera with a moving plate holder which carried a sensitized photographic plate. Its movement was regulated by a big fly-wheel at the extreme right.
