Now turn over the slate and count up freight I make it upwards of 25,000 pounds a year. If I had you at the desk, I'd shew you a bill of items. Now comes "SUBTRACTION," deduct cost of engines, wear and tear, and expenses, and what not, and reduce it for shortness down to 5,000 pounds a year, the amount of interest.
If there are, the size of the ship would prevent their showing themselves very quickly, and since they can't move the ship, it seems to me that they'll let us know shortly that they're around. Probably, with the engines stopped, their main weapons are useless, but they would doubtless have some sort of guns. I'm highly in favor of using the car.
High pressure engines, it is true, have no air pump to work; but the deduction of a pound and a half of pressure is relatively a much smaller one where the pressure is high, than where it does not much exceed the pressure of the atmosphere.
Wardrop delivered a lecture on repairing compound engines without the aid of the shops, and the men sat about on the cold machinery. The cross-head jammed in the guides leered at them drunkenly, but offered no help. They ran their fingers hopelessly into the cracks of the starboard supporting-column, and picked at the ends of the ropes round the shores, while Mr.
It was the first time that engines of warfare had led the way to an attacking force and the picture of the enemy fleeing before these new engines of terror spouting fire and destruction and rolling over trenches and machine gun emplacements, while cheering Tommies followed in their wake, will never be forgotten.
His wits must help him where his experience fails; and his experience must push him mechanically along the track of habit when successive buffetings have beaten his wits out of his head. In a day he must construct elaborate engines, roads, and implements which old civilization considers the works of leisure.
Up and down the long, long line aviators were scrambling into their machines while the sputter and throb of many engines punctured the night air. Some of these engines had as much as three hundred horse-power. The long continuing roar was nerve grating, yet inspiring. Swarms of small scouting machines were humming, spitting; these were the vipers or wasps of the air service.
I seized the telephone at my elbow, pressing upon the button which would call the chief engineer to the instrument in the bowels of the ship, only to find him already at the receiver attempting to reach me. "Numbers one, two, and five engines have broken down, sir," he called. "Shall we force the remaining three?" "We can do nothing else," I bellowed into the transmitter.
I shall now explain the making of the different kinds of engines which have been invented for raising water, and will first speak of the tympanum. Although it does not lift the water high, it raises a great quantity very quickly. An axle is fashioned on a lathe or with the compasses, its ends are shod with iron hoops, and it carries round its middle a tympanum made of boards joined together.
“I’ll have men on board of you by the time that your engines are running,” promised the lieutenant commander. “Engines?” That word came as a fortunate reminder to the submarine boy. He darted below, almost yanking Williamson from his berth, nearly pulling the machinist into his clothes. By the time that Williamson was really wide awake he found himself standing by the motors forward.
