I learned about two inventions and two inventors this week. The inventions are the lead chamber process and the spinning jenny. The inventor’s names are Richard Akrwright and James Watt. First, I learned about the lead chamber process. The lead chamber process increased production capability. Gay improved the process in the mid 1800s. John Roebuck used his wealth to invest in iron production. Second, I learned about the spinning jenny. It spun threads at once in 1764, then improved to over 100 by 1784. It helped contribute to the foundation of the industrial revolution. Third, I learned about Richard Akrwright. He was born in 1732. He was the father of the industrial revolution. He invented the water frame in 1768 and invented a new carding machine in 1775. Last, I learned about James Watt. He was born in 1736 in Scotland. He learned how to make instruments and opened his own business. He developed his condenser in 1763 and improved the steam engine’s effects. In 1780, he invented a new way of copying documents.
