Light Switch Tired of using old your old push-button light switch? As of 1916 William J. Newton and Morris Goldberg have come out with a new and improved patented light switch. Instead of pushing a button, all you have to do is either flick it up or down, and you’re light will automatically turn on. It’s now safer than the old push-button because it won’t control the whole mechanism directly, but instead through a series of springs and levers. Get your own revamped toggle light-switch today!| |

Neon Tube Lighting March 11, 1910
Georges Claude, a French engineer and inventor has created neon tube lighting. These tubes generate light when an electrical current is passed through rarefied gas within the tube. Claude first public demonstration of his large neon light was at the Paris Motor Show on December third through the eighteenth. Georges Claude is making a fortune selling his invention in the form of letters and words, changing the advertisement world forever. Neon lights are quickly becoming a popular fixture in outdoor advertisement and can even be seen in daylight. People are stopping and staring at the liquid signs dubbed “liquid fire”. First Auto Electric Car March 11, 1911

Charles Franklin Kettering from General Motors invents the first auto electric start car. The self-starting ignition was first installed in a Cadillac on February 17. Up to now automobiles were starting by hand cranking; a process requiring strength and reflexes.  His invention eliminates the need for hand cranking to start a car.  The Strength was needed to turn the hand crank connected to the large flywheel to turn the engine parts in motion. Quick reflexes were need to avoid the dangerous “kick back”. Kettering recognized that the electric starter needed high initial energy to turn the flywheel and start the engine’s pistons moving. Their starter uses the existing power from the cars battery. Once the pistons began to move ignition would take place in the cylinders and the car would start.

Traffic Light - 1912
A Police Officer in Detroit, Michigan named William L. Potts watched as more and more automobiles took to the streets. After thinking over ways to solve this traffic problem, he tried to figure out a way to adapt railroad signals for street use. Potts used red and green railroad lights and electrical controls to make a contraption he calls “the Traffic light”. The first of his lights was installed on the corner of Woodward and Michigan Avenues in Detroit. When the light turns red, the people on that side of the road stop while the crossing road gets a green light and continues on their way. Every few minutes, the lights change and the ones who originally had a red light now have a green and can continue driving. This system does not require an officer to be present but keeps traveling into heavy traffic areas bearable and simple. Within the year, Detroit had installed fifteen of these new traffic lights. When asked about his plans for the lights, Potts says he would like them to be all across the east side of the country within the next few years. Stainless Steel -1913
