James Watt and Matthew Boulton - steam powered manufactories

 James Watt was a Scot, born in Greenock in January 1736. His father was a skilled carpenter employing quite a number of people working mainly on ships. He was successful and respected; he owned shares in some of the ships he worked on. He married an equally respectable woman. The family story was tragic with three of five children dying in childhood with a further child losing his life on one of his father's ships. This left James as the surviving child.

James was not a strong child and lived his life with extended periods of ill-health. His mother and father taught him at home. When he eventually went to school he did not excel and suffered because of his delicate nature. However he was a wonderful story teller and mastered mathematics. He had played with wood and tools from early childhood and had excellent craft skills.

With this background a career as a mathematical instrument maker beckoned.

I tell of Watt's crucial role in the development of steam power in the context of three places: Glasgow where he started, Falkirk where he nearly succeeded, Birmingham where he found the right partner in Matthew Boulton

Matthew Boulton was born in 1728 son Matthew Boulton (senior) a silver stamper and piercer based in Birmingham. Matthew (junior) was educated in Deritend until he needed to join his father in the business. In spite of a rudimentary education, Matthew developed a passion for classics and through his work an interest in mechanics and science. In reaching the age of majority, his father took him into partnership and its wasn't long before Matthew was running the business.

Birmingham had many craftsmen like Matthew (senior) making 'toys' objects of delight for the middle classes. Over the years these objects had become increasingly gaudy and Matthew set his sights on producing well made objects of good taste. He invented the inlaid buckle. He worked with Huntsman of Sheffield on steel objects. He explored the work being produced by the French and copied it. He borrowed fine objects and had his craftsmen copy them. He went into clock making achieving success with both design and taste. He was selling to royalty and the aristocracy not only in England but across Europe. The death of his father provided a fine inheritance and a good marriage to Ann Robinson added to this. Samuel Smiles suggests he could have retired.

Matthew Boulton had other ideas; his passion was for business and he needed more space and built the iconic Soho Manufactory (page image with thanks to the Wellcome Collection). In this fine building, getting on for 1,000 craftsmen worked on buttons, clasps, watch chains and metal wares; candle sticks, urns and brackets; clocks and silver plate. It was the workshop of the world. He was a good employer keen to offer opportunity to young men of poor backgrounds. As I tell in my blog on London, he opened an outlet in Inner London as did his friend Josiah Wedgwood who produced in ceramics beautiful objects which would sit well alongside the Soho production. We do of course not remember Boulton for any of this. It was his championing of James Watt that transformed manufacturing.

The site of the Soho Manufactory had running water sufficient to power two water mills used largely for polishing. However in summer the water levels dropped and alternative horse power had to be found and was never really satisfactory. Boulton explored the inventions of Savery and Newcomen to pump water up to fill ponds to power the mills. The cost proved prohibitive. He then corresponded with Benjamin Franklin and his friend Erasmus Darwin on the design of steam engines. Good fortune led to Dr Roebuck in Falkirk inviting Boulton to invest in the Carron Iron works and this lead to Boulton eventually meeting Watt. They took an instant liking to one another.

I tell of their developing relationship in my blog on Birmingham but more so St Austell and Camborne where Watt struggled for acceptance of his inventions by the stuck in the mud Cornish. Watt also faced endless legal arguments over patents, but with Matthew's support won through. It wasn't only Watt's inventions, the addition of steam power to manufacturing enabled Matthew to take on the Royal Mint in mechanised coin production. Once again the struggle was not technical but for acceptance. Like so many entrepreneurs Matthew struggled as his demand for capital for ever exceeded its supply. His tenacity time and again won the day.

The original partnership of Boulton and Watt was dissolved in 1800 on the expiration of the reciprocating engine patent. James Watt was sixty four and exhausted; Matthew Boulton was eight years older and with ideas still occupying his brain, not least the Soho Mint which was his pride and joy. James Watt enjoyed nearly twenty years of retirement, dying in 1819. Matthew Boulton had died ten years earlier.

James Watt is commemorated through a statue in Westminster Abbey, a seated figure in Glasgow's George Square, and the Watt Memorial Engineering & Navigational School in Greenock. He is buried at St Mary’s Church, Handsworth, Birmingham.

West Country engine builders- Newcomen and Trevithick

 The West Country, Cornwall in particular, was where deep mines were first sunk, in search of metals rather than coal. The problem with depth was the water table which meant that mines would flood. To begin with, pumps were powered by animals or water and windmills. Something more powerful was needed and in stepped first Savery and then Newcomen.

Thomas Newcomen was born in Dartmouth in 1663. He became an iron monger, the title given to anyone making and selling iron goods. Some of his customers were quite probably Cornish tin miners and he saw at first hand the challenge presented by flooding. He would probably have seen the crude pump produced by Thomas Savery, a fellow Devonian, which had been nicknamed the 'miner's friend'.

In 1712, Thomas Newcomen made the vital breakthrough of the invention of the atmospheric steam powered pump which meant that mines could go even deeper. The Newcomen engine did not rotate in the way we think of steam engines on railways for example; it was static and relied on the production of a vacuum, under a piston sliding in the cylinder, to raise the water using atmospheric pressure. We can visualise this by thinking of some of the massive beam engines that have been preserved. These engines were soon employed in many mines.

Newcomen's engine relied upon atmospheric pressure and the cooling of the piston between strokes. James Watt made the vital step forward by adding a separate condenser meaning that the piston had no need to cool, thereby saving fuel.

Richard Trevithick was born near Camborne in Cornwall in 1771 just two years after Watt's invention of the condenser. His father, also Richard, was a mine 'captain', that is the mine's manager whose responsibilities included pumps which would have comprised some Newcomen and an increasing number of the more efficient Watt versions. Either way they were all beam engines. The young Richard had attended the local school but excelled neither in ability or enthusiasm; Richard loved the mines and their machines. He was an engaging man and physically extremely strong. As I tell in my blog on Camborne, the Cornish mine owners resented the need to pay Watt royalties for his invention and so many sought ways round the use of the condenser. It was Richard who found it in the 'high pressure' engine.

At the age of only nineteen, Richard was working with pumps in Cornish mines and was discovering improvements. These led him to London and the patent office where he met Davies Gilbert, a scientist, who would become a lifelong friend and collaborator. It was to Gilbert he took his invention of the high pressure engine, but it was Gilbert who found that the engine could power a locomotive on land. The issue was whether wheels would slip; Gilbert believed that friction would largely prevent this. Consequently Trevithick built at Camborne a locomotive powered by his high pressure engine in 1801; it was the first such in the world. A successor engine was tried on iron rails at Penydaren in South Wales in 1804 and a further version was on public display in London in 1808.

For Trevithick this was but a part of his prodigious output. He was also boring brass cannon, crushing stone, powering the bellows of blast furnaces, rolling mills and forge hammers. He adapted his engine to power the paddle wheels of a barge. I wrote of the Thames Tunnel in relation to Brunel. Trevithick was one of those first attempted the project. Although he didn't succeed he left the legacy of the idea of tunnelling using iron cylinder sections. In relation to steam engines he invented the Cornish boiler and building on this the Cornish engine. In both cases he continued to pursue the goal of efficiency.

In 1816 Trevithick sailed for Peru where miners were finding that atmospheric engines didn't work at altitude. The time he spent in South America although eventful was not productive and in 1827 he returned to Cornwall a poor man. He was as inventive as ever but the world had moved on. Stephenson's Rocket was soon to set the standard for steam locomotives. Other engineers were becoming more businesslike. Trevithick's final project was the design of a 1,000 ft iron tower to mark the passing of the Reform Bill of 1832. Sadly it was never built. Richard died at Dartford on 22 April 1833. His widow who had supported him through thick and thin survived him by therty years.
