After opening and closing a few small experimental plants, he constructed a plant near Ogdensburg, New Jersey, which gave him access to 19, acres of minerals. Edison managed the plant in Ogdensburg—a change of pace for the inventor. The endeavor presented issues from the very beginning. Edison could never quite get the lab to full capacity. He rejiggered machines a dozen times over at all steps in the process, from crushing to separating and drying.
The work came with a hefty price tag, with which Edison nor his investors could cover. Ore milling was a failed experiment Edison took a decade to let go—an uncharacteristically long time for the quick-stepping innovator.
His and the other major phonograph companies, including Victor and Columbia, manufactured the machines as well as the records they played. Edison believed his records were superior, DeGraaf says, and thought giving buyers access to more of his catalog was the only way to prove it. He rolled out the club in , sending subscribers 20 records in the mail each month. After two days, they selected the records they wanted to order and sent the samples on to the next subscriber.
The service worked well in small clusters of buyers, many of them in New Jersey. Up until this point, most markets were local or regional. After early success with the motion picture camera, Edison introduced a motion picture projector for non-commercial use in , with the idea they could serve as important educational tools for churches, schools and civic organizations, and in the home.
The machines were just too expensive, though, and he struggled to create a catalog of films that appealed to customers. Of the 2, machines shipped out to dealers, only were sold, DeGraaf says. The cylinder player that powered the tinfoil phonograph worked beautifully, for instance, but it was the disc that caused Edison problems; with home theater, the films themselves, not the players, were faulty.
Edison experimented with producing motion pictures, expanding his catalog to include one- and two—reel movies from documentaries to comedies and dramas. But by , people favored long feature films over educational films and shorts. Erica R. Post a Comment. Farber Bernie S. Metcalf Dr. Dean Sluyter Dr. Dolf de Roos Dominic O'Brien.

One day, Edison was sitting in his laboratory absent-mindedly rolling a piece of compressed carbon between his fingers.
He began carbonizing materials to be used for the filament. He tested the carbonized filaments of every plant imaginable, including baywood, boxwood, hickory, cedar, flax, and bamboo.
He even contacted biologists who sent him plant fibers from places in the tropics. Edison acknowledged that the work was tedious and very demanding, especially on his workers helping with the experiments.
He always recognized the importance of hard work and determination. I cannot say the same for all my associates. Edison decided to try a carbonized cotton thread filament.
When voltage was applied to the completed bulb, it began to radiate a soft orange glow. Just about fifteen hours later, the filament finally burned out. Further experimentation produced filaments that could burn longer and longer with each test.
Patent number , was given to Edison's electric lamp. The Edison lamp from our Attic is dated January 27, It is a product of the continued improvements Edison made to the bulb. Even though it is over a hundred years old, this bulb looks very much like the light bulbs lighting your house right now. The base, or socket, on this 19th century lamp is similar to the ones still used today.
It was one of the most important features of Edison's lamp and electrical system. The label on this bulb reads, "New Type Edison Lamp. Patented Jan. In the early s, Edison planned and supervised the construction of the first commercial, central electric power station in New York City. In , Edison began construction of a new laboratory in West Orange, New Jersey, where he lived and worked for the rest of his life. Before he died in , Edison patented 1, of his inventions.
The wonders of his mind include the microphone, telephone receiver, universal stock ticker, phonograph, kinetoscope used to view moving pictures , storage battery, electric pen, and mimeograph. Edison improved many other existing devices as well. From a discovery made by one of his associates, he patented the Edison effect now called thermionic diode , which is the basis for all electron tubes.
