This would mean that very little energy was absorbed by the cylinder every time it cycled. This would produce a considerable increase in the availability of energy to perform useful work. James would later meet the British Physician, chemist, and inventor John Roebuck. John was the founder of the Carron Works and it was he that encouraged James to make his own engine. James Watt and John would enter into a partnership together after he had made a small test engine.
His prototype was made possible by some loans from Joseph Black. Roebuck lived at Kinneil House, Bo'ness at the time and Watt would work in perfecting the engine in a small adjacent cottage to the house. The cottages shell and a very large part of one of his experiments still exist today. The engine's progress was stalled because of the difficulty in machining the piston and cylinder for his engine. Ironworkers at the time were more akin to blacksmiths that modern-day machinists.
They were, therefore, unable to produce the components with high enough precision. James Watt had become strapped for cash. This forced him to seek out employment. In Watt had become a land surveyor.
The next eight years of his life was consumed marking out routes for canals in Scotland. This work severely ate his time and his work on his new steam engine was severely set back. His partner Roebuck would sadly go bankrupt in An English manufacturer and engineer Matthew Boulton who was also the manufacturer of the Soho Works in Birmingham took over Roebuck's shares in Watt's patent. After eight years of land surveying, James would become jaded with the task.
Partly owing to his new partnership with Boulton, James moved to Birmingham in His partnership with Boulton would provide James with access to some of the best ironworkers in the world. This helped immensely with producing parts with enough precision needed for his engine. James Watt's patent was extended by the British Parliament in The same year Boulton and Watt would form a more official partnership that would last for more than 25 years. The financial support that Boulton provided allowed for the rapid progress of Watt's engine.
So fast, in fact, that by two engines were installed and fully functional. One engine was delivered and installed to pump water at the Staffordshire colliery. The other was used for blowing air into furnaces at John Wilkinson's forges.
In James would also marry again to his new wife Ann MacGregor. She bore him two more children. Over the next five years, right up to , James Watt would spend long periods of time in Cornwall. Here he installed and supervised numerous pumping engines for the lucrative copper and tin mines of the area. James's engine's had become very sought after as mine managers were looking for ways to reduce costs including fuel costs.
James Watt 's early engines were not manufactured by Boulton and Watt directly. Rather they were licensed out to be made by others following drawings and plans made by Watt. James would often be needed to serve as a consulting engineer for their production. Engine assembly and shakedown was initially supervised by Watt in person. Later by other men in their firm's employment. These early machines were pretty big. One of the first, for example, had a cylinder with a diameter of cm and a height of 7 meters.
They were required to be assembled in a dedicated building to house it. Boulton and Watt would charge an annual payment for the machines. Watt, for all his scientific and engineering acumen was no businessman. He was obliged to endure keen bargaining in order to obtain adequate royalties on his engines. Despite this, by James was doing pretty well financially. His partner, Boulton, however, was finding it hard to raise capital.
The following year Boulton saw a new market open up in the corn, malt, and cotton mill industries. James Watt was urged by Boulton to invent some form of rotary motion for his steam engines. The idea was to replace the reciprocating action of the original.
In he did just that. His so-called sun-and-planet gear provided the motion by means of which a shaft produced two revolutions for each cycle of the engine. In James was on a roll. He invented and patented the double-acting engine. This engine had a piston that pushed as well as pulled. The engine required a new method of rigidly connecting the piston to the beam. His solution was developed in when he invented the parallel motion. Watt would take on his suggestions and apply it successfully in By he also invented and added a pressure gauge.
This virtually completed what we know today as the Watt Engine. Orders quickly flooded in for his engine from paper mills, flour mills, cotton mills, iron mills, distilleries, canals, and waterworks. So many, in fact, that by Watt had become a wealthy man. His later years were not wholly consumed by his steam engines, however. Aged 19 he returned to Glasgow, where he set up his own business.
Before long he was recognised as a high-quality engineer, and employed on the Forth and Clyde Canal and the Caledonian Canal.
He was also involved in the improvement of harbours and in the deepening of Scottish rivers, including the Forth and the Clyde. The men became friends, and Watt provided model engines for Black to use in his lectures on the properties of heat.
Walking in a park near the Clyde, he suddenly he realised how he could make the standard Newcomen steam engine more efficient. He could use a separate chamber to condense steam without cooling the rest of the engine. In , Watt started a business in Birmingham with investor Matthew Boulton to manufacture his improved steam engine.
Watt and Boulton became leading figures in the Industrial Revolution. Watt continued to make improvements to steam engines, and patented other important inventions, such as the rotary engine and a steam locomotive. His achievements were recognised by fellow scientists. Watt's first wife, Margaret, died in childbirth in , leaving him with two young children. With the help of Boulton, he was able to create a steam engine with two separate condensers making it extremely efficient for its time.
In time, Watt and Boulton continued to work together. Watt and Boulton founded their new company known as Boulton and Watt in the year This was an early British engineering and manufacturing firm mainly in the business of designing stationary steam engines. Soon, multiple companies had gotten their hands on the improved steam engine and were eager to test it. Once the steam engine was known as a successful piece of equipment to power other machinery, factories all around soon invested in them and started using them in their factories.
With the steam engine being so efficient, companies started to invest because it made the production of manufactured goods quicker and more efficient. With that, more and more companies started to rise and run with the new industrialized businesses. With the steam engine being so successful more companies and factories started to emerge, leading to more industrial plants producing goods. Once these factories started to emerge, the industrial revolution had taken off.
All over England, factories used the steam engine to power machines, such as the spinning mule and the power loom. Boulton and Watt successfully ran for over one hundred years. Eventually, in , Bolton and Watt was forced to shut down as it could not be run anymore. With the help of multiple inventors, Watt created the most successful and efficient steam engine of its time.
In all honesty, the name of John Watt familiar but i did not know anything about him or his inventions in detail till the article. His invention of the steam engine was the embodiment of the industrial revolution. This creation improved the transition time of technology during that period but also had contributions to modern society. Watts mind and innovation was before his time.
It is always interesting to learn about innovation, but it is also nice to learn what it is being adapted for. This article shows that expanding knowledge to fit a problem can lead to the betterment of society. I also noticed that it seemed easier for him to improve the engine by himself, nowadays it would be extremely difficult to due that on ones own, this is because we are starting to reach a point where it takes more time to get the same amount of improvement.
I learned about John Watts in high school. He was definitely ahead of his time with the steam engine. That was the kickstart to the industrial revolution, and it greatly impacted the 18th century up to todays date.
Technology was not the same after this invention. Since then, we have evolved as a species, and we can thank John Watts. I remember learning about John Watts and the steam engine back in 10th grade.
I always just found him so astonishing, how he was so ahead of his time. Creating the steam engine became the foundation of the industrial revolution, which made a giant contribution in the 18th century and in present time as well.
Thanks to the engine, technology greatly evolved and we are able to mass produce just about everything.
