nessman. Whenever he made any money he immediately sunk the l winnings in score of new enter prises. Many of these failed, and | the inventor was always nnOrtgag- l ing a successful invention to dozens | of unsuccessful onese But Edison | cared little for money. He was one of those far too rare characters who believe in living a life of ser vice. He was always the intellec- tual. prodigal. Invention after in- vention poured from his mind. | There were, for instance:
 His electrical pen and duplicat- I ing press, which would reproduce and manifold writing-an inven- ton foreshadowing the modern mimeograph.
 His phonograph-abOut which Edison said: If there is one thing which really did invent, it is the phonograph.
 His feeder and main system for the distribution of electric light and power, which did away with the need for and the tremendous cost of isolated plaets and the substitution of grea. central sta tions.
 His device to control the speed and power of an electric ssotor by compound wiring.
 | His three-wire system, one of the most valuable of electrical in- ventions, by attaching two dyna- mos with neutral wire between l the two mains, a tremendous saw ing in copper used in transmission was effected.
 I His safety fuse, strip of lead and in alloy which volitilized and opened an electric current when a short circuit occurred which other wise would have caused the copper wires to become so hot from ex- cess of electric current as to set fire to inflammable substances in contact with the wires.
 His grasshopper telegraph, for telegraphing fro ma moving train.
 His Ediphone. Back in 1890 Major Hammer used the phono- graph for dictating all his corrc- spondence at his office, and m
 1905, Edison perfected the Edi- phone, now used extensively.
 His kinetoscope. Edison was the original inventor of the motion I picture camera and his kinetoscope was the groundwork for the mod- ern motion picture machine, pr Newton, an Episcopal minister in Newark, invented the first celluloid
 film used in cameras, and the East man Company, of Rochester. later paid his heirs a huge sum for his work. Up to that time glass , plates had been used. but Edison invented the first continuous film used in motion pictures. His belt conveyor. a belt used to convey away materials. widely used today in the ore and other : industries.
 His storage battery, widely In use today. A
 His primary battery, which gen. erated its own electricity by means of the reaction of chemicals while the storage battery stores up the current from dynamos and gives it off.
 His cement kiln, by which the production of cement was increas- ed from 30 barrels a day to 1000.
 His incandescent lamp and elec- tric lighting system. his greatest invention.
 Mis- Jumbo dynamo. which trans- lated the mechanical energy of the steam engine into electrical cur rent. Without 1t the production of electrical current would have been
 insignificant.
 Once Hammer asked Edison:
 What do you consider the out standing achievement of your car eer?" Without a moments hesti- tation he replied: The Jumbo dynamo"
 His ore separator and concen- ] trator. a method for separating magnetic iron ore from encasing rocks. Powerful magnets drew the iron ore out of crushed rocks as they passed in front of them. ' His giant grinding and crushing rolls. These rolls could take huge rocks and pulverize them in almost , the wink of an eye. This inven- ton increased efficiency of the con crete business enormously. Con- crete comes from trap rock, etc, and, but for this device, which quickly ground up the rocks. road , building might have waited long ] time for an adequate supply of l concrete.
