The lamps were partly of the horseshoe filament paper-carbon type, and partly bamboo-filament lamps, and were of an efficiency of 95 to 100 watts per 16 c.p. I can never forget the impression that this first view of the electric-lighting industry produced on me. Menlo Park must always be looked upon as the birthplace of the electric light and power industry.
The Electric-Lighting Plant is also located in this building. Not only does this Division light the buildings and grounds of the Institute, but it furnishes light to individuals in the town of Tuskegee, which is, at present, without other electric-lighting facilities. In 1895 the school suffered the loss by fire of its well-appointed barn, together with some of its finest milch cows.
It began at a hole inside a hut, and ran underground for quite forty yards, to a point about five yards outside the enclosure. Some of our chaps passed through it. In a large tin shed near the enclosure was a fine electric-lighting plant for lighting this strange prison on the open veldt. This morning the Captain came back, to our great delight.
Supplies were heaped on motor trucks, and the officers in charge of supplies and equipment lived in automobiles which had been fitted up like rooms. The supply and equipment departments had their own electric-lighting system and their separate wireless.
There are a number of modern commodities now practically standardised: the bicycle, the cheap watch, the ordinary tradesman's delivery automobile, the farmer's runabout, the country doctor's car, much electric-lighting material, dynamos, and so forth. And also, in a parallel case, there is shipbuilding.
Under 50 lbs. of steam it develops sufficient power to run a small electric-lighting installation, or to do other useful work on a moderate scale. Piston, 1-1/2 inches diameter; 1/2 inch long. Stroke of piston, 2-1/4 inches. Connecting rod, 5 inches long between centres; 5/16 inch diameter. Piston rod, 5-1/8 inches long; 1/4 inch diameter. Valve rod, 4-1/8 inches long; 3/16 inch diameter.
"Captain Jinks has not studied political economy. It's all a matter of supply and demand." "I'm ashamed to say I haven't," said Sam. "It must be very interesting, and I'm much obliged to you for telling me about it." "I suppose it's too early to do anything definite about concessions for trolleys and gas and electric-lighting plants," said the editor. "Not a bit of it.
It is all very well to threaten; but my impression is that any member of Town Council or any individual of Philadelphia who attempts to do such a thing will be lynched by the first telephone subscriber he meets. This practice of running overhead wires has great disadvantages when the wires are used for electric-lighting purposes as well as for ordinary telephone or telegraph purposes.
The month of May passed with few incidents of importance. Hurley, our handy man, installed our small electric-lighting plant and placed lights for occasional use in the observatory, the meteorological station, and various other points. We could not afford to use the electric lamps freely. Hurley also rigged two powerful lights on poles projecting from the ship to port and starboard.
Consequently, in order to protect its interests at all points, the Edison Company had found it necessary to pursue a vigorous policy of instituting legal proceedings against the infringers of these various patents, and, in addition to the large number of suits on the lamp alone, not less than one hundred and twenty-five other separate actions, involving some fifty or more of Edison's principal electric-lighting patents, were brought against concerns which were wrongfully appropriating his ideas and actively competing with his companies in the market.
