1 Chapter 6 – The Second Industrial Revolution Section 1 - The Age of Invention
2 The Age of Invention Industrial Innovations Steel ,000 tons $100/ton,000,000 $12/tonThe Bessemer ProcessDeveloped by Henry Bessemer in Great Britain and William Kelly in the USMethod of steel making that burned off the impurities in molten iron using a blast of hot air from a blast furnaceHelps usher in the Ind. Rev. - used in constructing railroads and rail cars, high rise buildings, bridges, nails, wire, and in machinery
6 OilDevelopment of a process to refine oil was as important to industrialization as advances in steel production.Edwin L. Drake – 1st to use a steam engine to drill for oil (Titusville, Penn.) – “Drakes Filly” produced 20 barrels of oil per day.Elijah McCoy – the son of runaway slaves, invented a lubricating cup that fed oil to parts of a machine while it was running.Received a patent – a guarantee to protect an inventors rights to make, use, and sell an invention
7 Transportation Railroads Cheap steel/the Bessemer Process – significant impact on RR expansionRapid increase in RR lines led to a more efficient network of rail transportation1st transcontinental RR finished in 1869Central Pacific and Union Pacific RR’s joined in Promontory, UtahGeorge Westinghouse – developed a compressed air break – improved RR safetyRR’s increased western settlement and stimulated urban growth by making travel affordable and easy.Railroad’s impact on the economy is immeasurable
9 How did advancements in steel production effect the railroad industry How did advancements in steel production effect the railroad industry? Write your response in your notebook.
10 The Horseless Carriage Innovations in oil refining led Nikolaus A. Otto to invent the first internal combustion engine powered by gasoline in 1876.1893 Charles and J. Frank Duryea used this engine to build the first practical motorcar or “horseless carriage”AirplanesUsing the int. comb. engine, Orville and Wilbur Wright developed one of the first working airplanesOn Dec. 17, 1903, near Kitty Hawk, NC, Orville Wright flew the first powered plain for 12 seconds/ 120 feet
12 Communications Telegraph Telephone Typewriter Samuel F.B. Morse developed the telegraph as a means of communicating over wires with electricity.Business orders could be sent to distant locations in moments.The telegraph grew in conjunction w/ the railroad.Morse Code – dot-and-dash message codeTelephonePatented by Alexander Graham Bell in 1876Early phones required operators to connect callers – many women filled these new jobs.TypewriterDeveloped by Christopher Sholes in 1867Revolutionized communicationsJobs as typists offered women the opportunity to work a skilled position for the first time
18 Edison and Menlo ParkThomas Alva Edison – America’s most influential inventor – his inventions includeThe electric vote recorderThe telegraphic stock tickerThe phonograph 1877the light bulb 1879He improved the telephoneDeveloped the first electric power plant (used Direct Current DC)Opened a workshop in Menlo Park, NJ, where he assembled a team of researchers where he promised to deliver “a minor invention every ten days and a big thing every six months or so.”
