2 Chapter 6 – The Second Industrial Revolution Section 1 - The Age of Invention

3 The Age of Invention I.Industrial Innovations 1.Steel a ,000 tons $100/ton b ,000,000 $12/ton c.The Bessemer Process i.Developed by Henry Bessemer in Great Britain and William Kelly in the US ii.Method of steel making that burned off the impurities in molten iron using a blast of hot air from a blast furnace iii.Helps usher in the Ind. Rev. - used in constructing railroads and rail cars, high rise buildings, bridges, nails, wire, and in machinery

4 Blast Furnace

5 Steel Mill 1

6 Steel Mill 2

7 2.Oil a.Development of a process to refine oil was as important to industrialization as advances in steel production. b.Edwin L. Drake – 1 st to use a steam engine to drill for oil (Titusville, Penn.) – Drakes Filly produced 20 barrels of oil per day. c.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

8 II.Transportation A.Railroads 1.Cheap steel/the Bessemer Process – significant impact on RR expansion a.Rapid increase in RR lines led to a more efficient network of rail transportation b.1 st transcontinental RR finished in 1869 Central Pacific and Union Pacific RRs joined in Promontory, Utah 2.George Westinghouse – developed a compressed air break – improved RR safety 3.RRs increased western settlement and stimulated urban growth by making travel affordable and easy. 4.Railroads impact on the economy is immeasurable

9 Promontory Point Celebration

10 How did advancements in steel production effect the railroad industry? Write your response in your notebook.

11 B.The Horseless Carriage 1.Innovations in oil refining led Nikolaus A. Otto to invent the first internal combustion engine powered by gasoline in Charles and J. Frank Duryea used this engine to build the first practical motorcar or horseless carriage C.Airplanes 1.Using the int. comb. engine, Orville and Wilbur Wright developed one of the first working airplanes a.On Dec. 17, 1903, near Kitty Hawk, NC, Orville Wright flew the first powered plain for 12 seconds/ 120 feet


13 III.Communications A.Telegraph 1.Samuel F.B. Morse developed the telegraph as a means of communicating over wires with electricity. 2.Business orders could be sent to distant locations in moments. 3.The telegraph grew in conjunction w/ the railroad. 4.Morse Code – dot-and-dash message code B.Telephone 1.Patented by Alexander Graham Bell in Early phones required operators to connect callers – many women filled these new jobs. C.Typewriter 1.Developed by Christopher Sholes in Revolutionized communications 3.Jobs as typists offered women the opportunity to work a skilled position for the first time

14 Samuel F.B. Morse


16 Alexander Graham Bell



19 IV.Edison and Menlo Park A.Thomas Alva Edison – Americas most influential inventor – his inventions include 1.The electric vote recorder 2.The telegraphic stock ticker 3.The phonograph the light bulb He improved the telephone 6.Developed the first electric power plant (used Direct Current DC) B.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.
