Signature
George Westinghouse, Jr (October 6, 1846arch 12, 1914) was an American entrepreneur and engineer who invented the railroad air brake and was a pioneer of the electrical industry. Westinghouse was one of Thomas Edison’s main rivals in the early implementation of the American electricity system. Westinghouse’s system using alternating current ultimately prevailed over Edison’s insistence on direct current. In 1911, he received the AIEE’s Edison Medal ‘For meritorious achievement in connection with the development of the alternating current system light.

Early years
Westinghouse was the son of a machine shop owner and was talented at machinery and business. He was only 19 years old when he created his first invention, the rotary steam engine. At age 21 he invented a “car replacer”, a device to guide derailed railroad cars back onto the tracks, and a reversible frog, a device used with a railroad switch to guide trains onto one of two tracks.
Thomas Edison was one of his main rivals due to the fact that they were both very intelligent inventors. At about this time he witnessed a train wreck where two engineers saw one another, but were unable to stop their trains in time using the existing brakes. Brakemen ran from car to car, on catwalks atop the cars, appling the brakes manually on each car.

Westinghouse Steam and Air Brakes (U.S. Patent 144,006)
In 1869 at age 22 he invented a railroad braking system using compressed air. The Westinghouse system used a compressor on the locomotive, a reservoir and a special valve on each car, and a single pipe running the length of the train (with flexible connections) which both refilled the reservoirs and controlled the brakes, applying and releasing the brakes on all cars simultaneously. It is a failsafe system, in that any rupture or disconnection in the train pipe will apply the brakes throughout the train. It was patented by Westinghouse on March 5, 1872. The Westinghouse Air Brake Company (WABCO) was subsequently organized to manufacture and sell Westinghouse’s invention. It was in time nearly universally adopted. Modern trains use brakes in various forms based on this design.
Westinghouse pursued many improvements in railroad signals (then using oil lamps) and in 1881 he founded the Union Switch and Signal Company to manufacture his signaling and switching inventions.
Electricity and the “War of Currents”
Main article: War of Currents
In 1875, Thomas Edison was still a relative unknown in the United States. He had achieved some success with a “multiplex telegraph” system that allowed multiple telegraph signals to be sent over a single wire, but had not yet obtained the recognition he wanted. He was working on a telephone system but was upstaged by Bell. Edison bounced back quickly from the setback to invent the phonograph, bringing him renown. In 1878 Edison invented an improved incandescent light bulb, and realized the need for an electrical distribution system to provide power for lighting. On September 4 1882, Edison switched on the world’s first electrical power distribution system, providing 110 volts direct current (DC) to 59 customers in lower Manhattan, around his Pearl Street laboratory. Lewis Latimer received a patent for an improved process for manufacturing the carbon filaments in light bulbs. These improvements reduced the manufacturing time and increased quality. During his life he had worked with and for Alexander Bell, Hiram Maxim and Thomas Edison.
Westinghouse’s interests in gas distribution and telephone switching logically led him to become interested in electrical power distribution. He investigated Edison’s scheme, but decided that it was too inefficient to be scaled up to a large size. Edison’s power network was based on low-voltage DC, which meant large currents and serious power losses. Nikola Tesla was working on “alternating current (AC)” power distribution. An AC power system allowed voltages to be “stepped up” by a transformer for distribution, reducing power losses, and then “stepped down” by a transformer for consumer use.
A power transformer developed by Lucien Gaulard of France and John Dixon Gibbs of England was demonstrated in London in 1881, and attracted the interest of Westinghouse. Transformers were not new, but the Gaulard-Gibbs design was one of the first that could handle large amounts of power and was easily manufactured. In 1885 Westinghouse imported a number of…(and so on) To get More information , you can visit some products about , . The melamine fruit plate products should be show more here!
