Needless to say, the voice of the inventor, however imperfectly reproduced, was hailed with great enthusiasm, which those who witnessed will long remember. In this machine, the barrel was fitted with a crank, and rotated by handle. A heavy flywheel was attached to give it uniformity of motion. A sheet of tinfoil formed the record, and the delivery could be heard by a roomful of people.
Fourteen thousand horsepower would this dam furnish. Cotton mills, factories, and manufacturing plants would rise up as the green corn after a shower. The spindle and the flywheel and turbine would sing the shrewd glory of Okochee. Along the picturesque heights above the lake would rise in beauty the costly villas and the splendid summer residences of capital.
"Not sufficiently wide awake to listen to your talk, damn you!" The American smiled nastily. "Maybe not, but this is a case of having to. Say! ever been in one of those big machine shops and seen a giant flywheel swizzling round at three hundred revs. a minute? Guess you wouldn't be gink enough to put out a hand and try to stop it. Never saw any machine yet that develops more power than I can."
He had a machine in his lab which would begin to turn a flywheel when he blew a chord on a harmonica. He could stop it by blowing a sour note. He claimed that this power was all around, but that it was easiest to get it out of water. He claimed that a pint of his charged water would run a train from Philadelphia to New York and back and only cost a tenth as much as coal."
In its upward stroke the piston was free to move; but in its downward stroke it was connected with a ratchet, and the partial vacuum formed after the explosion beneath the piston, together with its own weight in falling, operated through a rack, and caused rotation of the flywheel. The great objection to it was the noise it produced, and the wear and tear of the ratchet and rack arrangements.
This is why, when once the engine stops in mid-air, it can not be started again. Or at least if it is started it is mostly a matter of chance in getting it to go under compression or by the spark. There is no chance for the aviator to get out and whirl the propellers which are, in a measure, what a flywheel is to an automobile.
I cannot cast you a flywheel for a factory engine; so will try at something smaller, and will reproduce a medallion portrait of Her Majesty, in cast iron, the original of which is silver, commonly valued at half a crown. From the time I light the furnace until I turn you out the finished casting I shall perhaps keep you eight or nine minutes.
The captain looked round with the sickness of deadly fear in his eyes. "Don't make us go up there like this," he begged hoarsely. "For God's sake, don't do that!" Payne paused with a hand on the flywheel. The dread in the captain's eyes was obviously genuine. "Don't make us take you up there, mister," he repeated. "You wouldn't if you knew." "Knew what?" "We can't bring any one up there."
In the rotary design the crankshaft of the engine is stationary, and the cylinders, crank case, and all their adherent parts rotate; the working is thus exactly opposite in principle to that of the radial type of aero engine, and the advantage of the rotary lies in the considerable flywheel effect produced by the revolving cylinders, with consequent evenness of torque.
Nobody had ever even dreamed of motor-cars when that road was made, so you have to travel slowly and manoeuvre whenever you meet anything if you don't want to be killed. Even as it was, we got mixed up with a big automobile loaded with fish-baskets. Our flywheel was on the ground, running helplessly round and round, screaming horribly, while both chauffeurs abused each other.
