Numerous experiments have been made by Edison to find the bees-wax which is best adapted to receive the record, and he has recently discovered a new material or mixture which is stated to yield better results than white wax. The wax is moulded into the form of a tube or hollow cylinder, usually 4 1/4 inches long by 2 inches in diameter, and 1/8 inch thick.
The political sentiments that the Exposition celebrated were not such as to find general sympathy in monarchical Europe, so that the "crowned heads" were conspicuous by their absence. It was not, of course, by way of theatrical antithesis that Edison appeared in Paris at such a time. But the contrast was none the less striking and effective.
The captain of their largest boat had died suddenly, and they wanted a message taken to another captain who lived about fourteen miles from Ridgeway station on the railroad. This captain had retired, taken up some lumber land, and had cleared part of it. Edison was offered $15 by Mr.
Nicola Tesla and John Hays Hammond, Jr., worked out the idea, and Edison was to give the last touches; but as Edison is a German prisoner, they can't wait for him. They are going to try the thing on New Year's night against the German dreadnought Wilhelm II in Boston Harbour." "Blow up the Wilhelm II?" "Yes, but the Germans are warned in advance.
The perforated strips were prepared in thirty minutes by ten persons, and duplicated by nine copyists. But to-day, nearly thirty-five years later, telegraphy in America is still practically on a basis of hand transmission! Of this period and his association with Jay Gould, some very interesting glimpses are given by Edison.
Edison informed me that as a marine engine started before the ship left New York and continued running until it reached its home port, so an engine for his purposes must produce light at all times. That was a poser to me, for a five-hours' run was about all that had been required up to that time. "A day or two later Mr.
The other difficulty above referred to was one that had also occupied considerable thought and attention of many workers in the field, and related to the perforating of the dash in the transmission tape. It involved mechanical complications that seemed to be insurmountable, and up to the time Edison invented his perforating machine no really good method was available.
The first "Jumbo" Edison dynamo had gone to Paris; the second and third went to London, where they were installed in 1881 by Mr. Johnson and his assistant, Mr. W. J. Hammer, in the three-thousand-light central station on Holborn Viaduct, the plant going into operation on January 12, 1882.
Every department of mechanics was stimulated and benefited to an extraordinary degree. Copper for the circuits was more highly refined than ever before to secure the best conductivity, and purity was insisted on in every kind of insulation. Edison was intolerant of sham and shoddy, and nothing would satisfy him that could not stand cross-examination by microscope, test-tube, and galvanometer.
An evidence of the activity in this direction is furnished by the fact that six revenue cutters were launched at this port in these brisk days of its prime. Samuel Edison, versatile, buoyant of temper, and ever optimistic, would thus appear to have pitched his tent with shrewd judgment.
