Most of the companies answered that they were too busy with their regular business to undertake the building of such a motor for us; but one company replied that they had motors rated at 8 horse-power, according to the French system of ratings, which weighed only 135 pounds, and that if we thought this motor would develop enough power for our purpose they would be glad to sell us one.
The vessel I had charge of which I had brought out from England, was one of the finest double-screw steamers that had ever been built by D n; of 400 tons burden, 250 horse-power, 180 feet long, and 22 feet beam and was, so far as sea-going qualities, speed, &c., went, as handy a little craft as ever floated.
The feature most noteworthy in connection with the running of this type of engine was its flexibility; the normal output of power was obtained with 1,150 revolutions per minute of the crankshaft, but, by accelerating up to 1,400 revolutions, a maximum of 147 brake horse-power could be obtained.
Electric and magnetic stresses, acting parallel or at right angles to the other, exist in the same space and to indefinite degrees, neither modifying the direction nor amount of either of the others. These various stresses have been computed to represent energy, which if it could be utilized, each cubic inch of space would yield five hundred horse-power.
Siemen, tell us please how the steamer is lighted?" said George. "We have fifty miles of insulated wire in the "Campania" for the electric current generated by our two dynamos, which give us 1350 sixteen-candle power lights, equal to a total of 22,000 candle power, absorbing 135 horse-power. We also use large electric reflectors and search lights to pick up buoys on a dark night.
The engine thus shows as very economical in consumption, as well as very light in weight. The A.B.C. 'Dragon Fly 1A 'is a nine-cylinder radial engine having one overhead inlet and two overhead exhaust valves per cylinder. The cylinder dimensions are 5.5 inches bore by 6.5 inches stroke, and the normal rate of speed, 1,650 revolutions per minute, gives 340 horse-power.
He put it aside with a superb indifference to the opinion which his companions might form of him. "Ah, yes," he said, carelessly. "Since the car is gone, as you say, that is so." And he turned again to Servettaz. "It was a powerful car?" he asked. "Sixty horse-power," said Servettaz. Hanaud turned to the Commissaire. "You have the number and description, I suppose?
Anxious to realise his theories further, he constructed a twenty horse-power engine on the regenerative plan, and exhibited it at the Paris Universal Exhibition of 1855; but, not realising his expectations, he substituted for it another of seven-horse power, made by M. Farcot, of Paris, which was found to work with considerable economy.
At each end of the vessel, near the stem and the stern, is a pair of screws, similar to the propellers of a steam-ship, and worked by a couple of small steam-engines of three horse-power each, one being placed just above and behind each pair of screws.
A man, however, who stands still under a load is exerting no horse-power whatever, and this accounts for the fact that no constant relation could be traced in various kinds of heavy laboring work between the foot-pounds of energy exerted and the tiring effect of the work on the man.
