R.E. Crompton - pioneer of electrical engineering

 The Cromptons were a wealthy Yorkshire family with extensive estates and the young Crompton grew up knowing he was destined for career in the army or diplomatic service. It was a visit to the Great Exhibition of 1851 that gave young Crompton then aged six quite different ideas. He had travelled to London on a railway train pulled by six steam engines. To add to this were Daniel Gooch's broad gauge Lord of the Isles and Thomas Crampton's Liverpool. He had caught the steam bug and set about making his own steam road vehicle the Bluebell. As is the way with invention, this first iteration failed.

Crompton was gazetted as an ensign in the 3rd Battalion of the Rifle Brigade was was sent out to India. Steam followed him for he saw how painfully slow transport was in India, but also how good the roads were. The answer was a vehicle called the Primer with rubber tyres. This simply did not have the power and, if it did, the tyres slipped. So back to the drawing board and Ransome, Sims and Head of Orwell Works in Ipswich. The result was the Chenab pulling an omnibus capable of seating 130 people. In the event the payload was Crompton's new wife and an entourage to provide for the every need of the Chenab. The journey was astonishing for the time, being all the way to Wolverhampton. Apart from the length of the journey, it became known for the first recorded instance of car sickness.

As I write in my blog on Chelmsford, it was this East Anglian town that brought Crompton to electricity for which he is best known. The route, though, was circuitous. Two cousin had bough the Stanton Ironworks in the Erewash Valley and were keen to begin production of iron pipes. They engaged R.E. Crompton to manage the project to bring the works into use. The timescale was such that 24 hour working was required and this needed lighting. Crompton had heard of the work of the French Gamme with rudimentary dynamo and arc lamp. This proved effective and Crompton went on to develop it as I tell in the blog.

So much of invention seems to be about collaboration. Crompton was contacted by Joseph Swan of Newcastle and he visited to be met with a bright display of incandescent comprising a filament suspended in a vacuum within a glass globe. The two men went on to collaborate on lighting installations in a number of great houses. An interesting aside was the birth of the trade of wiring contractors said to have taking up the slack from bell hangers. Another collaboration was with the Swiss engineer Sulzer, whose name also appears when British Railways moved away from steam to diesel electric. With Crompton it was in the context of power transmission where Sulzer had used some of Crompton's dynamos to generate electricity to power electric motors.

Crompton secured his first large scale contract in Vienna which had suffered dreadful fires in its opera house and theatres from defective gas lighting. Electricity was the answer and Crompton installed Crompton-Willans generating sets to provide DC power at 400 volts taken down to 100 volts for the swan incandescent bulbs. From this success he provided power for the new Kensington Court Estate, again using DC. At this time, as I wrote in my blog on Edison, AC was becoming increasingly used including by Ferranti at Deptford. Nonetheless for lighting DC remained more reliable to a few decades to come.

A home laboratory is clearly what everyone needs and Crompton one at his Kensington home where he would explore electricity alongside Faraday and Kelvin.

Crompton was not one to be confined to particular areas of engineering. He was a keen cyclist and turned his attention to the improvement of road surfaces.

In his final years he advocated a national electricity grid to allow the population to spread out across the country reducing overcrowding in industrial areas. Surely we can see the need for this now with the north south divide.

Stafford manufacturing history

 A power house of British electrical engineering, Stafford was of course a shire town but one that was soon outgrown by other towns in its county. One reason was that the man road route following the course of the Trent by-passed it. When the canals came they too passed it by until a passage was created by dredging the river Sow and adding an canalised section.



The tradespeople of Stafford carried on the common trades, but slowly a larger group emerged whose business was making shoes. The wearing of shoes had become more common in London, the growing industrial towns and the colonies and so a strengthening demand developed for Stafford's shoe makers. In his book Stafford Past, Roy Lewis suggests that one name drew ahead of the field, that of William Horton. In many ways like Manchester cotton merchants, he had a network of outworkers for whom his workshop would cut the leather for soles and uppers and the outworkers would stitch them and return them to him for payment and the next batch of leather. At one time he is said to have had one thousand outworkers. Finished shoes would be despatched by canal to the growing urban areas. The Napoleonic wars boosted demand but then competition from the lower paid Northampton shoe makers attracted trade away.

Railways did not pass Stafford by, rather the town became something of a hub for Staffordshire's part in the growing rail network. Workshops were set up and successive stations built. More significantly the town embraced massive marshalling yards where wagons arrived and were despatched right around the country. Not surprisingly locomotive manufacture took hold and W.G. Bagnall emerged as a leader.

As with the other shoe towns, the advent of American sewing machines for shoes led first to strikes as men refused to work on machine stitched leather. In time, as elsewhere, machines became a fixture along with factory production. Stafford's factories found themselves specialising in women's shoes and the firm Lotus became the best known of Stafford's factories. As elsewhere, foreign competition shrank the workforce to one or two specialised factories.

Supporting the shoe making trade, there emerged a cohort of manufacturers of the equipment needed to make shoes but also the packaging, laces and polish the wearer would need. The British United Shoe Machinery Company was set up by its American counterpart and took over the shoe related business of W.H. Dorman. This company would move into motor vehicles with the Redbridge Motor Works and aero engines with Adams. In the First World War they developed the interrupter gear that enabled machines guns to fire between the blades of a spinning propeller. After the war, the company built its first diesel engines. In 1959 it acquired W.G Bagnall and two years later became part of the English Electric. Later still it would join with Perkins diesels of Peterborough.

At the start of the twentieth century, Stafford attracted the British Siemens Brithers whose premises at Woolwich were becoming too small to house both its cable manufacture and its business of dynamos and electric motors. It was these latter two which Siemens moved to Stafford. Siemens Dynamo works later joined the group of companies which in 1919 formed English Electric. I write of this in How Britain Shaped the Manufacturing World.

Roy Lewis writes of the arrival in 1930 of George Nelson as managing director of English Electric and how he encouraged its growth in a very hands on way, his home being through a garden gate in the factory fencing. The Second World War saw the factory produce tanks, bombs and a range of electrical equipment. In 1960 the company opened a new transformer factory and in 1968 merged with GEC. I write of this in Vehicles to Vaccines. In 2015 the Stafford Grid and Power businesses became part of the American General Electric, now GE Vernova, which is working on high voltage transmission for the transition to net zero.

Stafford was also home to British Reinforced Concrete Engineering Company and in the Stafford Salt and Alkali Company.
