Essay #27 History Of Inventions
Hello, in today’s lesson I will be talking about the lead chamber process, the spinning jenny, Richard Arkwright, and James Watt. All right let’s get started!
The lead chamber process
John Roebuck went to medical school in Edinburgh Scotland; he graduated medical school and set up a medical practice. He, however, continued to nurture his interest in chemistry, mainly applied chemistry. He knew about the importance of sulfuric acid. Sulfuric acid, is used for fertilizers, pesticides, dyes, and metals. Sulfuric acid is made from sulfur, salt peter, and water. Roebuck invented the led chamber which increased the production capability of sulfuric acid. The led chamber, was a “glass jar” with lead lined rooms. By the way, these rooms were as big as a large bedroom with a 12 foot roof. John Roebuck did not patent his invention; he kept it a secret. He built a huge factory in Edinburgh, the only problem was that wasn’t so secret after all, because you already know how big the chamber was, and by the way, imagine 100 of those, so now you have an idea how big that factory was. Therefore, other people began to use his technology as it became well known. Overall I’d say that John Roebuck was a great inventor and a very smart man.
The spinning jenny
James Hargreaves was born in 1721 in England, he was a poor, uneducated weaver. One day, he had a flash of insight which led to the creation of the spinning jenny, which could spun 11 threads at once. It spun 11 threads in 1764, and over 100 threads by 1784. Thread production finally caught up to the increased cloth production. Hargreaves built several spinning jennies for his own use. One spinner could now do the job of 100 spinners. That’s a lot.
Richard Arkwright was born in 1732 in England, and he apprenticed as a barber. He then turned to wigmaking in the 1750s; he invented a waterproof wig dye. After wigmaking started to become less popular, he then turned to textile manufacturing and hired the one and only, John Kay. He invented the water frame in 1768, he also invented a new carding machine in 1775. He developed the early factory system in the 1770s; this meant, he built little cottages or houses next to his factories and that’s where people lived, they were close to work, and saved them time commuting. He employ children seven and up, wow, and he use steam engines for his mils. Overall John Arkwright was a very good, and smart, inventor. Did you know that he was knighted, that means the king and queen very much appreciated what he did for their village, or town, and decided to give him the title of sir Richard Arkwright.
James Watt was born 1736 in Scotland. He learned to make instruments and open his own business. The University of Glasgow offered him work. A friend introduced him to steam power in 1759. He developed a condenser around 1763. Watt is primarily associated with the development of the steam engine. He improved its efficiency greatly. Overall, Watt was an influential man with other inventors.
