I doubt if the muffler of an auto would cut down the sound of an aero engine to any appreciable extent. But, of course, I'll try along those lines." "They have mufflers or silencers for guns and rifles," went on Ned. "Couldn't you make a big one of those contraptions and put it on an aeroplane?" "I doubt it," said Tom, shaking his head.
Then the engine, puffing and blowing, set to work again, and dragged the train away. The children watched the tail-lights of the guard's van disappear into the darkness. This was the first train the children saw on that railway which was in time to become so very dear to them.
"More trouble!" exclaimed the professor. He opened the slide covering the bull's-eye windows and looked out. All about was swirling muddy water. "Can you see anything?" the inventor called to Jack, who was in the conning tower. "We've run into a mud-bank, and are stuck fast," called back the boy. "Reverse the engine!" called the professor. "Maybe we can back the ship out."
Then Rovinski, bounding around like a wild animal in a cage, took out a key he had brought with him, opened the trap-door, lifted it back, and gazed down. He could see a beautifully cut well, but that was all. But no matter how deep it was, he intended to go down to the bottom of it. He started the engine and lowered the car to the ground.
He took in all sail, struck his topmasts, and resolved to rely entirely on his engine. But the peril seemed only to increase. Enormous waves caught the schooner and carried her up to their crests, whence again she was plunged deep into the abysses that they left.
"When we aren't dependent on the wind to fill our canvas, we neglect watching every little weather change. She's going to blow by and by." "Do you think it will be a real storm?" asked Ruth, who sat beside him at the steering wheel and engine, watching how he managed the mechanism. "Maybe. But with good luck we will make Beach Plum Point long before it amounts to anything."
It will not be difficult, however, to introduce the pressure into the rules as an element of the computation, whereby the result will be applicable both to high and low pressure engines. Q. Will you apply this mode of computation to a marine engine, and first find the diameter of the piston rod?
Could a motor-plough work in a fog? Presently, she who knew every inch of the ground and every tree upon it, became aware that she was close to the Chetworth gate. Suddenly the rattle of an engine and some men's voices caught her ear. The plough, sure enough! The sound of it was becoming common in the country-side.
He prepared a model upon his return to Soho, using a crank connected with the working-beam of the engine for that purpose, which worked satisfactorily. There was nothing new in the crank motion; it was used on every spinning-wheel, grind-stone and foot-lathe turned by hand, but its application to the steam-engine was new.
He stepped out from the dozing lime trees and held his hat up like a flag. 'Take your seats, he cried as of old, 'for the Starlight Express. Take your seats! No luggage allowed! Animals free! Passengers with special tickets may drive the engine in their turn! First stop the Milky Way for hot refreshments! Take your seats, or stay at home for ever!
