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.

East Anglia manufacturing history

 A predominantly agricultural region with historically a heritage of farm equipment manufacture. The presence of one of the world's top universities is of course significant. In much earlier history East Anglia was impacted by invasions from Rome and then Anglo-Saxons, Danes and William the Conqueror. Later it benefitted from successive influxes of Flemish weavers and Huguenots. Each of these invasions left their beneficial mark not least at Sutton Hoo near Ipswich.

Cambridge

The University is a major collaborator with British industry. It was from where ARM came. Read more in this link.

King’s Lynn

A fishing port for many centuries. British Sugar has a large factory at nearby Wissington

Great Yarmouth

Where the American Birds Eye began freezing fish in Britain. It became part of Unilever.

Lowestoft

Home to one of the Pye Radio factories. At nearby Bungay, Clays print books. Birds Eye frozen vegetables factory now owned by Nomad Foods.

Norwich

One of the great early wool towns. Home to Norvic Shoes and a centre of shoe making. The Boulton Aircraft company developed from a woodworking firm. The company was re-established in Wolverhampton in 1936 as Boulton Paul and in 1961 joined Dowty Group. Mackintosh of Halifax bought AJ Caley of Norwich and there developed Quality Street and Rolo. You can find more by following this link.

Thetford

Charles Burrell Ltd were the largest employer in Thetford and at one time were the largest manufacturer of traction engines in the world. In 1919 they joined Agricultural and General Engineers and when that company failed in 1932, Burrells closed with the loss of many jobs. Fisons first set up here.

Ipswich

Ransomes were the biggest employers and Fisons main factory was here having originated in nearby Thetford. I tell more by following this link.

Harwich and Felixstowe

Together with Ipswich, these are known as the three Haven ports on the North Sea thanks to their deep harbours.

Colchester

Thought to be the first English town a century before the Romans. A wool town in the middle ages and in the nineteenth century a centre of mechanical engineering with Paxman engines and Crompton's dynamos. You can read much more by following this link.

Southend on Sea

Ekco built a factory here in 1930 to manufacture radio and plastics. As I observed in the design review of the Festival of Britain, EK Cole was especially good at diversifying. In the Second World War, Ekco’s factory at Southend was considered too vulnerable to air attack and so they relocated in part to Aylesbury, and, in part, to a 19th century mansion near Malmesbury in Wiltshire. They made radio for bombers and airborne radars and walkie-talkies for infantry.

Basildon

The neighbouring village of Fobbing was where the Peasant's Revolt began in 1381 with Wat Tyler leading a march on London. Basildon is a town with a distinctly agricultural heritage and which moved into the twentieth century with brick works producing seven million bricks a year. The works were used by the military during the First World War and thereafter were dismantled. It was designated a new town after the Second World War. New Holland tractors set up in 1964 and Marconi manufactured here. Read more by following this link.

East Midlands manufacturing history

 Textiles and footwear. Engineering built on an agricultural heritage and steel based on ore in Leicestershire and Northamptonshire. The image is of Lincoln Cathedral.

Nottinghamshire

Nottingham

One of the five towns of the Danelaw. Hosiery was centred on the East Midlands and so Nottingham along with Derby and Leicester. This led to framework knitting and then to Nottingham lace. I write about framework knitting in the page on Leicester (below). Nottingham suffered from dreadful overcrowding and this combined with a decline in the hosiery trade after the Napoleonic wars led to the action of the Luddites.

The city was home to Jesse Boot and pharmaceuticals, Raleigh Bicycles (later part of TI plc) and Stanton and Staveley steel and spun pipes (formerly part of British Steel and before that Stewarts & Lloyds). It was also home to John Player cigarettes and a good deal of Courtaulds and other textile manufacturers. Follow this link to read more about Nottingham.

Long Eaton

Long Eaton was home to lace making and furniture. In the late 19th century three large tenement lace mills were built one financed by the notorious financier Ernest Terah Hooley who was born in the town. You can read more about long Eaton manufacturing in this link.

Beeston

Just outside Nottingham, Beeston was home to Plessey Telecommunication following their purchase of Ericcson. Long before then it was home to the Humber Company before their move to Coventry. It was the vacant Humber factory that in 1901 was occupied by the National Telephone Company (later taken over by British Ericcson) to manufacture telephone equipment under licence from the American Bell and Edison. Nearby Chilwell had been home to a massive shell filling factory in the First World War and I wrote of this in Ordnance. In the Second World War it became home to the Army Centre for Mechanisation of which I wrote in War on Wheels.

Sutton in Ashfield

A coal mining town which became home to hosiery manufacturer, Pretty Polly. Parker-Knoll upholstery moved here

Mansfield

William Hollins set up its mill in Pleasley that same year, attracted by the availability of water and a climate kept damp by the number of trees. Labour was provided by a workhouse; many of the workers were children
At the Great Exhibition of 1851 I noted that William Hollins of Mansfield in Nottinghamshire exhibited both cotton and wool which when combined was patented as Viyella.

Worksop

One of the major producers of liquorice. Home also to hat making and furniture. Also Sharwoods, owned by RHM and then Premier Foods, make their famous curry sauces.

Newark

Home to British Sugar, later part of Associated British Food. Home to Worthington Simpson Pumps, later part of a joint venture between Ingersol-Rand and Dresser Pumps. Ransome and Marles Bearing Co became part of Ransome Hoffman Pollard bearings formed at the initiative of the IRC in the sixties. It became a subsidiary of Ingersol-Rand. After a management buy out, the bearings business eventually became part of the Japanese NSK.

Leicestershire

The company began in 1825 as a colliery, but refocused on bricks with annual production of 3 million in 1914, 10 million in 1939 and 18 million in 1946. Ibstock Brick became a punlic company in 1963. By 1990 it had 5,000 employees expanded through acquisition including Redland and Tarmac brick businesses. The business weas bought by CHR but then sold to management in 2015. It was then re-floated. Its Eclipse factory near Leicester was opened in 2018.

Loughborough

Home to Brush Electric Machines . I write of the American Brush Company in my blog on American electricity. The British Brush company operated first in London but grew out of its premises and looked for a suitable place for expansion. The site selected was in Loughborough next to the Midland Railway where the Falcon Engineering Works had been built by Henry Hughes who had begun by building carriages, railways carriage and eventually steam locomotives. Brush Electrical Engineering became a major manufacturer of electric powered locomotives whilst continuing with steam locomotive particularly for export markets. Ladybird produce their children's books in the town. Nearby Mountsorrel became home in 1941 to the Alvis workforce relocated from Coventry after the bombing of 14 November 1940. After the war the factory was bought by Rolls-Royce and only closed in 1994. British Gypsum producing plasterboard is at East Leake, now owned by St Gobain.

Market Harborough

Summingtons made Liberty corsets and the famous Liberty bodice.

Melton Mowbray

Promoted as the food capital of England, this market town is home to Samworth Brothers makers of sandwiches and porkpies and Clawson Dairy makers of Stilton and other cheeses. Until 2000, the neighbouring village of Old Dalby was home to the army depot maintaining our missiles. Mars chose the town for its Pedigree Petfood factory. Stanton & Stavely had an iron works manufacturing fitments and manhole covers at Holwell just outside Melton.

Derbyshire

Derby

One of the five towns of the Danelaw. Home to Rolls-Royce, railway and engineering history. I tell more about the city's manufacturing story with the help of a visit to the Derby museum of making.

Spondon

In 1923 British Cellulose had changed its name to British Celanese and by the 1930s was producing Celanese filament yarn well suited to the fashions of the twenties and thirties. Its acetate drape was being used in competition with silk. British Celanese was later bought by Courtaulds. In the Second World War, British Celanese manufactured parachutes and underclothing. By the end of the war, they employed 20,000 people. In conjunction with Courtaulds, ICI formed British Nylon Spinners to exploit the Du Pont patent of Nylon for the manufacture of parachutes.

Belper

Was home to Glowworm and Parkray boilers, part of TI plc and then Hepworth Ceramic plc.

Langley Mill

The Valley works became a shadow factory producing a variety of armaments. It was then repurposed by Vic Hallam to manufacture prefabricated buildings. Aristoc manufactured silk hosiery and GR Turner manufactured wagons.

John Robinson set up a business here in 1839 making pill boxes. In the fifties the company patented the first disposable nappies and now as Robinson plc make a whole range of packaging material.

Burton on Trent

At one time it was home to thirty breweries. The Branston pickle factory was repurposed as a Central Ordnance Depot for Army clothing in the Second World War. Read more in this link.

Burnaston

Toyota built a plant here in the early 1990s to manufacture motor cars for the UK and European market

Cromford

Richard Arkwright’s water frame massively increased the speed of spinning cotton. Cromford is the site of his first factory and also John Smedley wool knitters.

Alfreton

Home to Thornton's Chocolates founded in Sheffield in 1911. Butterley was an engineering company at nearby Ripley and produced cast iron (for St Pancras Station and the Falkirk Wheel) and bricks, the latter became part of Hanson and then Heidelberg Cement. The engineering business was bought by Slater Walker and merged with Crittall. Read more in this link. Also nearby is the Denby Pottery.

High Peak

Home to Swizzles Matlow.

Northamptonshire

Northampton

New Town designated in 1968. Home to boot-making, becoming busy during the First World War with huge demand from the army. From this came shoe making which now is at the quality end of the market with Churches. The town was home to Express Lifts, Britain's largest manufacturer of lifts, and their test tower built in 1982 is now a listed building. I tell more in this blog.

Corby

A new town designated after the Second World War in 1950. Stewarts and Lloyds in effect relocated their steel making in the interwar years but steel production ceased in the eighties. Tata Steel has a presence in the town manufacturing thin walled tube. I tell more in this blog.
