Page 56 - Then we started another engine and threw them in parallel. Of all the circuses since Adam was born we had the worst then. One engine would stop and the other would run up to about a thousand revolutions, and then they would see-saw.
Page 56 - gang" that ran., but, in this case, only to the end of the room, afterward said: "At the time it was a terrifying experience, as I didn't know what was going to happen. The engines and dynamos made a horrible racket, from loud and deep groans to a hideous shriek, and the place seemed to be filled with sparks and flames of all colors. It was as if the gates of the infernal regions had been suddenly opened.
Page 57 - About that time I got hold of Gardiner C. Sims, and he undertook to build an engine to run at 350 revolutions and give 175 horse-power. He went back to Providence and set to work and brought the engine back with him. It worked, but only a few minutes, when it busted.
Page 56 - What was the matter ? Why, it was these Porter governors ! When the circus commenced the men who were standing around ran out precipitately, and some of them kept running for a block or two. I grabbed the throttle of one engine and EH Johnson, who was the only one present to keep his wits, caught hold of the other and we shut them off.
Page 57 - When he reached this period, I gave orders for the works to run night and day until we got enough engines, and when all was ready, we started the main engine.
Page 13 - A complete system of distribution for electricity had to be evolved, and as I had to compete with the gas system this must be commercially efficient and economical, and the network of conductors must be capable of being fed from many different points. A commercially sound network of distribution had to permit of being placed under or above ground, and must be accessible at all points and be capable of being tapped anywhere. "I had to devise a system of metering electricity in the same way as gas...
Page 9 - Or take this account which he gives of his work on lighting, and notice his capacity for infinite detailed attention equally to things small as to things great. "Just at that time (1878) I wanted to take up something new, and Professor Barker suggested that I go to work and see if I could subdivide the electric light so it could be got in small units like gas.
Page 59 - We were not very commercial," Edison explained about the electric company's early days. "We put many customers on, but did not make out many bills." During these times, Edison faced constant cash shortages. Outside the Pearl Street service area, however, Edison's fortunes looked brighter. By 1889, at the age of thirty-nine, he was a millionaire and his companies' combined assets totaled almost $10 million.
Page 43 - As I was on all the time, I would take a nap of an hour or so in the day time — any time — and I used to sleep on those tubes in the cellar. I had two Germans who were testing there, and both of them died of diphtheria caught in the cellar, which was cold and damp. It never affected me,
Page 13 - One of the largest problems of all was that I had to build dynamos more efficient and larger than any then made. Many electrical people stated that the internal resistance of the armature should be equal to the external resistance; but I made up my mind that I wanted to sell all the electricity I made and not waste half in the machine, so I made my internal resistance small and got out 90 per cent of saleable energy. "Over and above all these things, many other devices had to be invented and perfected,...
