Soon there were trains a mile long that on level ground could be pulled at 55 mph. Lonnie Johnson is a former Air Force and NASA engineer who invented the massively popular Super Soaker water gun. Will this bill help? To the world, he was known as the "Black Thomas Edison," and his numerous inventions and improvements to existing technology seem to support that characterization. George Westinghouse patented his first air brake in 1869. Air brakes have been around for almost 150 years, but when they fail the results can be disastrous, as the world saw during the Quebec train derailment. They tried adding the lever system to cars along the length of the train, but this required a “brakeman” to be at each lever. According to Wikipedia, before air brake systems were invented by George Westinghouse in 1869, brakemen had to run from car to car, on top of the train cars, to apply brakes manually in order to stop a train.The new invention had a failsafe built in that if any leaks occurred, the brakes would automatically apply and the train would stop until the leak was repaired. 30, 1910) was a Black inventor so successful that he was sometimes referred to as "The Black Edison." Jet fighters often have a speed brake, which is a large metal plate just behind the cockpit that can be hydraulically raised to increase drag and braking. Then Westinghouse invented the train air brake system. Lineside electronic "hotbox" and dragging-equipment detectors check on today's longer trains more . Early in his career during the summer of 1881, Woods contracted smallpox, which was in its last years as a major health threat in the United States. Railroad Brake Shoes - 30 pages - $10.25 - Paul North. In the 1860s trains were having many wrecks, and there were many reasons, but a major problem was the braking system did not work well. In the train’s cab was a lever, which when pulled pressed a wooden block against one of the drivers (power wheels). There are still many places in the Pittsburgh area carrying Westinghouse's name. Background. Still, Westinghouse had the upper hand and ultimately proved AC was the better technology: He not only bought Nikola Tesla's AC technology patents in 1888 and convinced Tesla to work for him, but he also laid out the case for its safety when, in 1893, he lit up the World's Columbian Exposition in Chicago using his AC generator.
