Porter built many engines with certain common characteristics i.e., high piston speed and revolutions, solid engine bed, and babbitt-metal bearings; but there was no electric driving until 1880, when Mr. Porter installed a high-speed engine for Edison at his laboratory in Menlo Park.
The concentrated fuels were not known in those days, and heat-economising appliances were not invented. It was the invention by Gottlieb Daimler of the high-speed gasoline engine, in 1885, that really gave an impetus to the building of efficient automobiles of all powers.
Joe said between mouthfuls: "Funny way for anything to take off, riding on it looked like a truck." "It is a truck," said Talley. "A high-speed truck. Fifty of them specially made to serve as undercarriages so pushpot pilots can practice. The pushpots are really only expected to work once, you know." Joe nodded. "They aren't to take off," Talley explained. "Not in theory.
Even Captain Nemo's personal insights were denied me, because that mystifying individual didn't appear one single time during our high-speed crossing. I estimate that the Nautilus covered a track of some 600 leagues under the waves of this sea, and this voyage was accomplished in just twenty-four hours times two.
Frank J. Sprague spoke on behalf of the American Institute of Electrical Engineers of the debt of electricity to the high-speed steam-engine. He recalled the fact that at the French Exposition of 1867 Mr. Porter installed two Porter-Allen engines to drive electric alternating-current generators for supplying current to primitive lighthouse apparatus.
A perforated drum revolved at high speed within it. The box of spot-remover hit the door. The door dented in, hit the high-speed drum inside, and flew frantically out again, free from its hinges and turning end-for-end as it flew. It slammed into the thrower's companion, spraining three fingers as it knocked his revolver to the floor.
A high-speed frigate, the Abraham Lincoln, was fitted out for putting to sea as soon as possible. The naval arsenals were unlocked for Commander Farragut, who pressed energetically forward with the arming of his frigate. But, as it always happens, just when a decision had been made to chase the monster, the monster put in no further appearances. For two months nobody heard a word about it.
We have already illustrated several forms of these engines, and now publish engravings of another in which the most noticeable feature is the employment of separate expansion valves and very short steam passages. Many high-speed engines labor under the well-grounded suspicion of being heavy steam users, and their want of economy often precludes their employment. Mr.
But the old buck he seemed to be on the high-speed gear himself. First thing I knew he bumped me for fair, and then came back to stick me with his horns. But I didn't just care for knowing him any closer, and I rolled out of the way." "You managed to get your tree after that, didn't you, Steve?"
The experience of modern steam navigation points to the exclusive use and advantage of the screw propeller where great speed of shaft is obtainable, and the electric engine is pre-eminently a high-speed engine, consequently the screw appears to be most suitable to the requirements of electric boats.
