"What's the matter dad?" he asked as cheerfully as he could. "Have you been figuring over that gyroscope problem again, against my express orders?" and he laughed a little. "No, Tom, it's not the gyroscope that's worrying me." "What is it then?" "Those scoundrels are around again, Tom!" and Mr. Swift looked apprehensively about him. "You mean the men who stole the turbine model?" "Yes.
He did not reveal anything of this to his dear Princess, and talking to her on the turbine wore the clear brow of the philosopher; but he did feel that he was a much-tried man, and he behaved to the maid Annalise exactly in the way much-tried men do behave when they have found some one they think defenceless. Unfortunately Annalise was only apparently defenceless.
Of course we could not have done it had we not boldly adopted the new-fashioned turbine principle for her engines; but they work to perfection, and even when she is running at full speed one can scarcely feel a tremor in her."
Care should be taken, when the vacuum falls and the turbine slows down, to see that the water is shut off from the glands for fear it may leak out to such an extent as to let the water into the bearings and impair the lubricating qualities of the oil. Inspection At regular intervals thorough inspection should be made of all parts of the turbine.
The great, paved courtyard, flanked by the turbine houses and the wall, on one hand, and on the other by the oxygen tanks' huge bulk that loomed vaguely through the electric-lighted mist, now had begun to swarm with men. Flint saw a few forms lying prone under the hard glare of the arcs and vacuum lights. Others were crawling, writhing, making strange contortions.
The upper part had a dome in the middle, like a turret. The edge of the saucer- shaped object was thick and had vanes spaced about every foot, like buckets on a turbine wheel. Between each vane was a small opening, like a nozzle. The next reaction that the scoutmaster recalled was one of fury. He wanted to harm or destroy whatever it was that he saw.
He had many adventures on it, chief among which was being knocked senseless and robbed of a valuable patent model belonging to his father, which he was taking to Albany. The attack was committed by a gang known as the Happy Harry gang, who were acting at the instigation of a syndicate of rich men, who wanted to secure control of a certain patent turbine engine which Mr. Swift had invented.
After making several differently constructed wheels and testing them a number of times, he selected the best one and obtained a patent for it March 3, 1868, and called it "new turbine," which he still further improved and patented May 9, 1871.
With the turbine, on the other hand, any increase of vacuum, even up to the highest limits, increases the economy to a very considerable extent and, moreover, the higher the vacuum the greater will be the increase in the economy for a given addition to the vacuum. Thus, raising the vacuum from 27 to 28 inches has a greater effect than from 23 to 24 inches.
Because his education has been general in the field, and he now holds a position with a company manufacturing steam-turbines, say, he must "wise up," as the saying goes, on the subject of steam-turbines. It will do him no harm to trace back to its source all progress made in the field of turbine engineering and construction.
