The first transcontinental telegraph line is completed, allowing people across the country to communicate with one another almost instantly. Originally developed by Samuel Morse and Alfred Vail in the 1830s, Morse Code let people send telegraph messages easily.

George Pullman creates the first railroad sleeping car, the "Pioneer." Pullman later became president of the Pullman Palace Car Company. This company made and operated sleeping cars on contract with railroad companies. The company became so large that it had its own town for its workers just south of Chicago. Pullman workers held one of the most famous strikes of the 19th century in 1894.

Image: A patent application diagram shows a design for high-pressure steam valve. The cylindrical object is shown in cutaway view with a rod in the middle of the revealed space.
Elijah McCoy patents a steam engine self-lubricator. This device used the high pressure of steam valves to keep moving parts greased and moving smoothly. McCoy received more than 50 patents in his career, mostly for improvements to the steam engine. He founded his own company, the Elijah McCoy Manufacturing Company, in 1920
1876:
Image: A photograph shows a formally dressed, seated Alexander Graham Bell demonstrating his invention in front of a group of men dressed in suits and standing behind him.
Alexander Graham Bell receives the patent for the telephone. The telephone improved on the telegraph by using electricity to transmit sound. Several lawsuits over the true inventor of the device followed, but Bell ultimately won.
1879:
Image: A photograph shows four early incandescent electric light bulbs mounted in a row on a board for display.
Thomas Edison develops an improved incandescent electric light bulb. Among Edison's numerous other inventions were the phonograph, an improved telephone, and a motion picture camera.
1883:
Image: A blueprint drawing from a patent application shows the first machine to successfully attach the tops and bottom of shoes over the last, a mold in the shape of a foot. The individual parts of the machine are noted with letters and numbers.
Jan E. Matzeliger patents the first machine to successfully attach the tops and bottoms of shoes over the last, a mold in the shape of a foot. The machine could finish between 100 and 650 more pairs of shoes per day than a person doing so by hand. Shoe prices plummeted as machine-made shoes flooded the market.
1884:

From left to right: a bulb with filament beginning at the bottom and curving downward; a bulb with filament beginning at the bottom, rotating in a circle, and curving downward; a bulb with filament beginning at the bottom, and curving downward, upward, and downward again; a bulb with filament beginning at thTimeline - Text Versione bottom, rotating three times before curving downward.
Lewis Howard Latimer becomes the only African American member of Thomas Edison's inventing lab. He had already developed improved electric lamps and a light bulb filament. While working for Edison, Latimer wrote an engineering handbook about incandescent lights.
1885:
Image: Blueprint for an object from four different views. The object appears to be a rectangular box with covers that fold over its top and are fastened.
Sarah E. Goode becomes the first African American woman to receive a patent. Her cabinet bed allowed users to transform their beds into desks to save space in small city apartments. The bed had hinged sections that could be folded or unfolded as needed.

actuating the transition between these two states (open or closed) can be either a "toggle" (flip switch for continuous "on" or "off") or "momentary" (push-for "on" or push-for "off") type. An incandescent light bulb, incandescent lamp or incandescent light globe is an electric light which produces light with a filament wire heated to a high…
comparing todays choice of light bulbs by: Donald walker Most people in America has had a light bulb burn out on them. However with the changes in today’s technology there are many types of bulbs to choose from. Most of us would go to the local home supply store and grab a box of cheap bulbs and call it a day. Is that the best choice though? Let’s take a look at the world of incandescent, CFL (compact fluorescent), and LED (light emitting diode) light bulbs, which is the best choice for your wallet…
Display Type Used in… How it works Advantages/Disadvantages Incandescent lights Already done! The incandescent light works by having the highest possible amount of current flowing through the bulb. The more the current the more the heat produced which gets the blub to glow and thus giving of light. Already done! LED Lights Already done! LED’s are semiconductors, as electrons pass via this semiconductor the energy turns into light, Thus lighting up the bulb. Already done! Bell Buzzers Already done…
The first type on the left is Traditional incandescent (TI) which produces light with a wire filament heated by an electric through it until it glows, second bulb beside the (TI) is Halogen incandescent (HI) which has a small amount of a halogen such as iodine inside the bulb prevents wear on the filament allowing it to glow brighter, next to it on the right there is the Compact fluorescent (CFL) which is a fluorescent lamp designed to replace an incandescent lamp excited gas in a CFL tube emits ultraviolet…
The Light and the Electron Ty Wothe HIS/458 August 6, 2013 Gene Mann The Light and the Electron The discovery of the electron and the invention of the incandescent light bulb are among the most exciting and valuable innovations in human history. The incandescent light bulb produces light, and it is a very durable version of the earliest of light sources. Light bulbs and electrons go hand in hand as the electron plays a very important role in producing light. Both came into fruition during the 19th…
Lewis Howard Latimer Lewis Howard Latimer was an African American inventor and draftsman. His work was a critical factor in many things used today. He is also an inductee of the National Inventors Hall of Fame for his work on electric filament manufacturing techniques. Lewis Latimer was born in Chelsea, Massachusetts on September 4, 1848. His parents were George and Rebecca Latimer. They had run away from slavery in Virginia six years prior to the birth of Lewis. Latimer and his four siblings…
facilities. Around the world the household and commercial sector accounts for around a third of electricity usage and lighting is almost a third of that. Majority of lighting is obtained from incandescent bulbs. Based on a 100 year old technology, the incandescent bulbs converts only 5% of the electric energy into light and waste the rest as heat. A huge amount of savings in electricity consumption can come simply from use of efficient lighting by all sections of customers, both BOP and non-BOP. From the…
they even had a professor named Harold Brown who went around talking to audiences... and electrocuting dogs and old horses right on stage, to show how dangerous alternating current was. Meanwhile, a murderer was about to be executed in the first electric chair at New York's Auburn State Prison. Professor Brown had succeeded in illegally purchasing a used Westinghouse generator in order to demonstrate once and for all the extreme danger of alternating current. The guinea pig was William Kemmler, a…
Chapter 29: LIGHT WAVES 03/18/13 Light is a wave – in many ways it behaves just like a wave. Light is also a particle – in many ways it behaves just like a particle. This week we study the wave properties of light. Next week we’ll study the particle nature of light. Cause of refraction Refraction is caused by the change in the speed of light from one transparent medium to another, and the wave nature of light. Consider two cart wheels…
helped strengthen the economy for businesses. More consumer goods were being produced and sold. Electricity got applied to underground trams and railways making transportation easier (Swirk). Railways were good for travel and transporting goods. Electric and gas powered vehicles also replaced the use of horses for transportation. Electrical motors were used in underwater submarines too. During the Civil War, submarines were often used for more secretive attacks (Veit). The invention of electricity…
