Thomas Edison is best known for his invention of the light bulb. Contrary to popular belief, Edison did not invent the light bulb; it had been around for several years. However, the electric lights of the time were unreliable, expensive and short-lived. More than twenty different projects by other inventors from all over the world were already underway when Edison entered the race for the invention of light bulbs.
Below is a list of Edison patents. Thomas Edison was an inventor who accumulated 512 patents worldwide for his inventions. Edison is credited with contributing to several inventions, such as the phonograph, the kinetoscope, the dictaphone, the electric lamp (in particular the incandescent bulb) and the autograph printer. He also vastly improved the telephone by inventing the carbon microphone.
Most of these inventions were not entirely original, but were improvements to previous inventions. However, one of Edison's major innovations was the first industrial research and development laboratory, which was built in Menlo Park and West Orange. In the second hundred patents, Edison continues his work with the telegraph. It also begins to patent electrical distribution and light.
This series of patents focuses mainly on phonographic, telegraphic, telephone and electrical generation and distribution. This series of patents contains patents for the phonograph, lamps, telephone, dynamo systems, engines and locomotives. In connection with the issuance of these patents, Thomas Armat joined Edison and sold him the patents for the machine known as Vitascope. By the end of this patent series, Ott was Edison's superintendent of experimenters.
This series of patents focuses mainly on the phonograph and other speaking machines. There are several battery patents included in this part of the legal protections. This electric pen, which Edison patented in 1876, used a rod with a steel needle on the tip to pierce paper for printing purposes. Of course, Edison also later invented the entire electrical service system to be able to power all the light bulbs, motors and other appliances that soon followed.
But he invented and commercialized a design that was the first to be durable enough to be practical and widely used. Read on to discover why members of Congress rejected a machine designed to make them more efficient, and how another Edison invention scared little girls and infuriated their parents. But in the early 20th century, the Victor Talking Machine Company phonographs that played records surpassed Edison's cylindrical phonographs in popularity. While the invention of the telegraph by Samuel Morse in the 1830s and 1840s made it possible for the first time to communicate over long distances, the device had its drawbacks.
Edison decided to take on the challenge of inventing a lighter, more reliable and more powerful battery. But while Edison Portland cement was used in many structures in New York City during the construction boom of the early 20th century, concrete houses never succeeded. The inventor, an agnostic who admitted that he had no idea if a spiritual world existed, spoke of his research in several magazines and explained to The New York Times that his machine would measure what he described as the units of life that are dispersed throughout the universe after death. Taking the idea of the telephone and the telegraph a little further, Edison announced in October 1920 that he was working on a machine to open the lines of communication with the spirit world.
However, the Edison storage battery was used in mining lamps, trains and submarines and became the most successful product of Edison's later career. Some people claimed that at a spiritism session in 1941, Edison's spirit told participants that three of his attendees owned the plans. In the late 1870s, Edison designed a vacuum bulb, in which a metal filament could be heated to create light. But Edison's work was not in vain: storage batteries became his most cost-effective invention and were used in miners' headlights, railroad signs and marine buoys.
In late 1877, he had a machinist build the device, using aluminum foil instead of wax, and Edison recorded the children's song “Mary Had a Little Lamb”. . .
