  1. Indicator 7-3.5Inventions and Technology in the “Machine Age” I. Inventions and Technology in the “Machine Age” (p. 121 – 128) – Many inventors contributed to the Industrial Revolution. The machines that were invented changed the lives of people around the globe. Eli Whitney and the cotton gin

  2. Machine-Made Cloth 1. John Kay invented the flying shuttle to speed up the weaving process. 2. Use the chart on p. 122 to complete this information:

  3. 3. William Kelly and Henry Bessemer worked to develop a method of turning iron into steel. Kelly received a patent, or exclusive ownership of an idea, on this invention. Today this invention is called the Bessemer process. 4. While iron was stiff, steel was flexible and strong. Steel became the material for building bridges, skyscrapers, and bigger machines.

  4. B. Steamboats and Railroads 1. Industry needed ways to transport, or carry, raw materials to factories and goods to markets. Inventors combines steam power with new methods of iron and steel production. 2. Railroad construction in Britain and the U.S. soared. 3. In 1807, American Robert Fulton designed the first steamboat, the Clermont.

  5. C. Rise of Mass Production 1. Mass production is the manufacture of huge quantities of identical goods at cheap prices. 2. Two concepts are part of mass production: a. interchangeable parts – developed by Eli Whitney. This means machine-made parts that are exactly alike can be more easily replaced and fixed. b. division of labor – assigning workers specialized tasks as goods move along a conveyor belt from worker to worker. This method became known as the “assembly line” and was used by Henry Ford to build low- cost automobiles.

  6. D. Electricity and Industry 1. Many scientific discoveries kept the Industrial Revolution moving forward. Some of the big inventions: a. Electricity – we all know how that changed the world! b. the telegraph – Samuel Morse helped messages to be carried long distances c. the light bulb – Thomas Edison lit up the world d. electric generators – produced electricity
