The Second Industrial Revolution • Industrial Innovations: (464-465) • Second Industrial Revolution: From 1865 to 1905 the United States experienced a surge of industrial growth • This new era of industrial transformation began with numerous discoveries and inventions that significantly altered manufacturing, transportation, and the everyday lives of Americans
The Second Industrial Revolution • Industrial Innovations: (464-465) • Coal and steam made possible the original Industrial Revolution in the United States. • Coal-fed steam engines powered factories. These factories in turn produced the goods that generated economic growth. • In the late 1800s an abundance of steel helped spur a second period of industrialization. • Steel was used in the construction of heavy machinery and mass-produced goods
The Second Industrial Revolution • Industrial Innovations: (464-465) • Steel: In the 1850s Henry Bessemer in Great Britain and William Kelly in the United States, both developed a method of steelmaking that burned off the impurities in molten iron with a blast of hot air • CALLED THE BESSEMER PROCESSS: it produced more steel in one day than the older techniques could turn out in one week • The increased availability of steel in the late 1800s resulted in its widespread industrial use. • The Railroad Industry began replacing iron rails with stronger, longer-lasting steel ones • Steel was used for: railroads, bridges, and buildings • Using steel to create a skeletal frame in buildings allowed architects to design larger, multistory buildings. • Steel is resistant to rust
The Second Industrial Revolution • Industrial Innovations: (464-465 • Oil: (465) • The process to refine oil affected industrial practices • Edwin L. Drake: used a steam engine to drill for oil • People thought he was nuts, so they called him “Drake’s Folly.” • Oil boom: prospectors referred to oil as “black gold” • Elijah McCoy: invented a lubricating cup that fed oil to parts of a machine while it was running – your car • McCoy received a patent – guarantee to protect an investors rights to make, use, or sell the invention.
The Second Industrial Revolution • Industrial Innovations: (464-465 • Transportation: 466-468 • Innovations in the steel and oil industries led to a surge of advances in the transportation industry • Brought Americans into closer contact with each other
The Second Industrial Revolution • Industrial Innovations: (464-465 • Railroads: 466-467 • The country’s first transcontinental railroad was completed in 1869. • Project was finished when the Central Pacific and Union Pacific railroads were joined to form a single rail line from Omaha, Nebraska, to the Pacific Ocean • By 1900, almost ½ a dozen trunk lines – or major railroads, crossed the Great Plains to the Pacific Ocean. This huge railroad grid joined every state and linked remote towns to urban centers • George Westinghouse – developed a compressed air brake. It increased railroad safety. • Railroads: increased western settlement; stimulated urban growth and provided many of the Country’s jobs • Network of railroad lines allowed companies to sell their products nationally
The Second Industrial Revolution • Transportation: (466-468) • The Horseless Carriage: (467) • It was a self-propelled vehicle and forerunner to the automobile in 1700 • Nicolas-Joseph Cugnot mounted the steam engine to a 3 wheeled carriage • Nikolaus A. Otto: invented the first internal combustion engine powered by gasoline in 1876 • Only the wealthy could afford these forms of transportation
The Second Industrial Revolution • Transportation: (466-468) • Airplanes: 467-468 • Orville and Wilbur Wright (The Wright Brothers) of Dayton, Ohio, developed one of the first working airplanes • December 17, 1903, in North Carolina, Orville Wright made the first piloted flight – 12seconds and 120 feet – in a powered plane
The Second Industrial Revolution • Communications: (468-470) • Telegraph: (468) • Samuel F. B. Morse developed the telegraph as a means of communication over wires with electricity – the Morse Code
The Second Industrial Revolution • Communications (468-470) • Telephone: 469 • Alexander Graham Bell in 1876 patented the “talking telegraph.”
The Second Industrial Revolution • Communications (468-470) • Typewriter (470) • Christopher Sholes developed the typewriter in 1867. • The typewriter gave more jobs to women who did clerical work and the main task was to type
