South Caradon Mine-The Webpage is now up and running

wp-1505842564505.jpg

A  South Caradon Home page is born

No new South Caradon Mine information this post; instead I have put together an index of posts so far.

The page will expand as this series of posts continues on its journey into the depths of the old ‘Views of South Caradon’ website. As it expands the listing will be grouped, sorted and arranged into a structure that will provide a useful resource for anyone wishing to know more about this important copper mine in South East Cornwall.

A new Tavistock Canal Book

Meanwhile I have just got my copy of Rob Waterhouse’s amazing book on the Tavistock Canal. A real classic of Industrial Archaeology.  For anyone who is researching John Taylor, the mining genius, this book is a must. Ask your local bookseller to get a copy, I suspect the hardback copies may soon disappear.

If you do not have a local bookseller then here is an Amazon link, but as I write this post none have yet turned up on their site for sale.

1838-William West’s Double beat valve and the scourge of cholera

Cholera was a dark shadow over Victorian British cities. Its cause was not grasped fully until after John Snow’s famous piece of cartography.  A cause that demanded the twin solutions of providing clean fresh water, and removing the sewage that contaminated it. William West, by accident, would play his part in removing the deadly disease from our streets.  This post is the story of that accident.

It was in December 1838 that the former East Cornwall Silver mine engine made her first strokes in London. This was an important event as it marked the first time a Cornish engine had been seen working in London. Boulton and Watt’s engines dominated the grand halls of the water work companies, and now this machine from the mines of Cornwall was to attempt to break into their domain.

The East Cornwall Mine Engine house

W7

It had not been an easy journey to get to this day. The East London Waterworks engineer, the young and gifted Thomas Wicksteed, had worked long and hard to convince his board that the high pressure Cornish Engine concept was the way forward. He had learnt much about the Cornish Engines from his friend John Taylor, and gathered the evidence needed to sway his board by touring Cornwall visiting the mines, many of which had West’s engines.  So on that winter’s day much was at stake.

W12

The impressive hall of the Old Ford engine house was packed with the Company Directors and their grand friends to witness their new purchase glide into life.  They stood in great expectation of that massive beam starting its first graceful strokes as it pumped their fresh Lea River water from the cistern up to a stand pipe, and from their out to their many customers. Under the watching eyes of William West and the foundry Nicholas Harvey, the engine driver started his mesmerising dance with his hands of manually operating the valves to bring life to the engine.

But as the engine gathered speed and the gallons of water stated to flow through the pipes it started to go wrong, horribly wrong. The engine started to shudder, the whole engine house started to shake, and soon, with top hats flying, the grand directors and their guests fled the building. Whist the guests stood outside relieved to have escaped with their lives, West and Holman remained inside in a desperate attempt to save their engine and reputations.

w13

With great speed West’s men set to work with urgent modifications. Soon the guests were ushered in to the now near silent hall to see their new engine effortlessly working away. As they out  headed towards their sumptuous celebratory dinner, none appeared to have noticed that new engine was just a sham. Not a single gallon of water was being moved.

West and Holman had recognised that it the pump, not the engine, that was fault. Despite of the advanced technology of the engine the pump was reliant on old fashioned, simple clack valves. Down a bottom of a mine they worked well, but here so close to the engine, and with so much water being moved they could not cope. On every closure they sent shock waves throughout the system threatening to destroy the engine and all around it. Their solution was simple, disconnect the valves and the vibrations stopped. But so did the pumping of water.

As the guests ate and drank, West and Harvey worked desperately to find an answer to the problem. Harvey rushed back to his foundry in Hayle with their hastily produced drawings, and by March their new invention was successfully running in Old Ford. It was an invention that did not stop their, soon it was installed in waterworks and canals all over Britain. West’s engines now became sought after far from his original market of Cornish Mining. That day in December, the day that almost ruined his engineering reputation, brought both him and Harvey great wealth. It would also play its part in  eradicating the feared cholera epidemics by giving the rapidly expanding cities the pumping power they demanded to bring fresh water to everyone.W4

Their invention was simple, and not really a new invention. It went under the title of a ‘ double beat self acting valve’. ‘Double beat’ refers to it having two faces, and  ‘self acting’ to the lack of valve gear. The trick of its operation lay within its shape, a shape which balanced the pressures on opening and closing.

 

Like many technical advances this was a result of evolution rather than revolution. West had taken the concept of double beat steam valves developed by earlier Cornish Engineers and made it larger, and self acting.

The steam engine went on to play another important role in engineering history. Now a Cornish engine was working in London, easy to visit by the great minds of the scientific establishment. No longer could the impressive performance being claimed by Cornish engines be dismissed as exaggeration, or that they broke the laws of nature. West’s engine became a showcase for Wicksteed to prove to those outside of the Cornish dominated metal mining industry that the high pressure single cylinder non- condensing engine ( the Cornish engine) was superior to Watt’s.

The old Ford engine would play one last part in the Cholera story, and that was a dark and fatal one.  Whilst all those engines pumped their clean healthy water to the urban populations, their impact on Cholera cases was in most cases incidental, because the link between cholera and waterborne infection had not been widely accepted. That link was finally, fatally  confirmed in 1866. In that year, Cholera’s final onslaught came through water provided by the East London waterworks, from water in their Old Ford Reservoir, which was fed by the River Lea, which an infected water closet in nearby Bromley on Bow drained  its waste.  Although many died from the outbreak, the lesson was finally learnt, and no longer would British graveyards become overloaded with bodies of the disease’s victims.

Lean’ s Reporter, John Taylor and some layers of history

History is never simple….the story of John Taylor’s involvement  in the ‘Cornish Duty Race’ is an example of the truth of this statement. I will resist the onion skin comparison, instead I will resort to the pile of stones image; lift up a stone of historical fact only to discover another one beneath. Keep lifting, keep digging and more facinating stories emerge. Here’s the first stone.

image

Steam engine development was accelerated by the duty race in Cornwall.
A simple statement is based on the fact that Cornish engineer’s competed to produce the most efficient engine.  It was the combination of the use of ‘duty’ as a unit of measurement and the public arena of Lean’s engine reporters that drove this desire to compete.

Duty was a measurement of performance against fuel used, its units were a strange mix:Pounds of water  lifted one foot by burning one bushel of coal. Lean’s Reporters were a regular produced publication produced by the Lean family that contained tables of mine engine performance.

In their heyday their was much publicity to be gained from being at the top of Lean’s table, and even more from breaking new records of performance. Taylor played a major part in this duty race;  a race that lifted Cornish engineering from stagnation to world prominence. Here are some significant stages in the battle.

1811 The reporter is started by Joel Lean, and the battle to be top of the tables commences.
The highest duty recorded was 22.3m at Wheal Alfred

1815 Woolf’s compound engine at Wheal Vor is the first engine to achieve 50m.

1827 Grose’s 80″ at Wheal Towan is recorded at 67m.

1827 Taylor’s 90″ was moved from Wheal Alfred to Consol’s, and renamed Woolf’s, where it returned a duty of 67m, a trial is demanded, one is run.

1828 Grose achieved 87m with his Towan engine, trial is demanded, a trial is run.

1832 Eustace’s 80″ at Wheal Darlington achieves 91m. Many of the other top slots in the table is filled with Hocking and Loam engines built for John Taylor.

1835 West’s Austen’s engine s recorded at 90m, a trial is demanded.

1835 in October William West’s Austen’s engine achieves 125m on a 24 hour trial, a record never broken.

1840 Hocking and Loam’s 85″ engine at Taylor’s United mine achieves 107m, the largest figure recorded in Lean’s

1850s onwards-duties decline the battle is over.

1905 last surviving issue is published.

Who won the duty race? This depends on interpretation, Taylor’s Hocking and Loam 85″ was the head of the table for sustainable duty, Austen’s William West’s engine for short term working. History remembers both.

Time to overturn the next stone.-

TaylorsEngine

The Reporter’s were not Lean’s, and Duty was not Duty.

The two foundations of this race are shakey, Duty is far from scientifically sound as a measurement, and the Lean’s did not create the Reporter that bears their name.

Duty had a fundamental flaw, bushels was a far from certain measurement. Its size could vary, and many reports did not define the bushel in use. Even when defined, accurate measurement would be a challenge in many circumstances, let alone the discrepancies introduced by wet coal.

In addition to this flaw their existed many over opportunities for difference between records. Detailed specifications of recording methods, and assumptions made, were not readily available, resulting in a lack of transparency on the derivation of the results. The basics were straight forward, measure the coal, record the stroke length and use a counter to keep tally of the number strokes made. But outside of this existed many variables that could change the final figure.

Even worse was the opportunity for fraud, engine men could perform all sorts of tricks to tweak the duty upwards, such as deliberately short stroking their engines.

These flaws became aired in public disputes, arguments and accusations that eroded the faith in the Reporter’s accuracy. When John Taylor’s engineer, Arthur Woolf, moved his 90″ from Wheal Alfred to Consolidated is increase in duty aroused suspicion. When Hocking and Loam’s engines at Consols did not degrade in performance in time, that aroused suspicions. When West Achieved 125 m that triggered heated arguments. When West withdrew all his engines from Lean’s after being accused of mis-reporting his whim engines’ performance, that definitely dented the confidence in the system.

Whatever the flaws inherent in the derivation of the figures, the concept of Duty created an spectacular improvement in steam engine technology.

Likewise the history of the Reporters is not as simple as their title appears. Although Joel Lean published the first one in 1811, it was Captain William Davey and Captain John Davey who instigated the concept. Joel was chosen to arrange the compiling of the publication, and to put his name to the brand.

On its own,  this fact is not overly significant to the story, but turn over another stone and it becomes murkier.

UnitedShaftPan

The vested interests.

I must thank Bridget Howard for shining a light under this stone, her book is an excellent read, and the Trevithick Society sell it.

Behind the Leans was hidden the Davey’s, but behind their involvement was another influence, Arthur Woolf, John Taylor’s engineer. Bridget Howard suggests that Woolf set up the reporter to promote his own engines, using Leans as a cover for hidden propaganda. After Joel Lean dies the corruption gets worse, with Woolf exerting pressure on his sons to distort the figures. Eventually the dishonesty causes a split between the two brothers, with John accusing his brother of being intimidated by :

” The menaces of self made men.”

John to formed his own reporter in 1827, and none of its mines had Woolf as an engineer.

So throughout his period as engineer for John Taylor Woolf was distorting the system that was supposed to be scientifically driving steam engine development. John’s Lean’s revelations left John Taylor in a precarious position. His reputation for honest openness was at threat, to many it appeared that he had colluded in a Woolf’s underhanded activities.

Is response was a campaign of justifying the accuracy of the reporting system, and proving the efficiency of Cornish engines. It was a campaign that resulted in many papers and talks. Its culmination was a book called ‘Historical statement of the Improvements made in the Duty performed by the steam engines in Cornwall.’ This book was published by the Lean’s, but it was Taylor’s concept, Taylor’s money was behind it, and Taylor arranged for the society to endorse it.

And so the stones of history have overturned, there is much more  to explore. But for now this blog has to move on again, after this wander around John Taylor’s life it will return back for a new look at William Wwp-1460413814023.pngest.

On the Economy of the Mines of Cornwall and Devon 1814

Here it is, the latest of my historic publication transcriptions on Cornish Mining.

image

In 1814, the mining genius, John Taylor, published a definite description of the ‘Cornish Mining System’, and this new publication by re-produces that important paper in a modern format, and includes additional information from a John Manley. 

Cornish mining methods dominated metal mining in the 19th Century. Cornwall’s miner’s and engineers exported their skills worldwide, wherever there was copper and tin underground, there was a Cornishman. Alongside the technical skills often came the financial and management systems of Cornish mining, it is those systems that this book describes. 

John Taylor’s name dominates the history of British metal mining. A key part to his success was the use of the ‘Cornish system’, a system that he describes clearly within this book. His words have been supplemented by additional material from the Editor. 

This short publication is essential reading for anyone wishing to understand the workings of the Victorian mining industry.

John Taylor’s St. Austell Mines-And a constructive rivalry

As this series of posts approaches its closure I finally get to bring William West into the story. He has had some brief appearances, but now the two paths start to intertwine.

Among the many Cornish mine’s that came under the Taylor’s control there was a group that merged to form a Taylor dominated district; that was those around St. Austell.  These coastal mines had been worked for many years, but from 1810 onwards they enjoyed a huge copper boom that made this district one of the most important in Cornwall.

John Taylor was behind this success, the  mines of Poolgooth, Pembroke Crinnis and Charlestown becoming very rich after he commenced working them.

Poolgooth

This was a mine with an ancient history, its workings being active hundreds of years before John Taylor’s arrival. By the 18th century the mine was one of the richest in Britain and its wealth justified the installation of an early 50-inch Newcomen steam engine erected in 1727 by Joseph Hornblower.  As technology moved on the engine was replaced in  1784 by a 58-inch Boulton & Watt engine. Taylor again updated the steam power in 1823 when he installed an n 80-inch William Sims engine.

From 1846 William West built several engines at the mine, some of which were built at his foundry in St. Austell.

 

Pembroke

 Pembroke Mine was started before 1815 by John Taylor and worked until 1877. For a while he was very successful, becoming the second largest mine in the county.

For a while west’s long stroke 80″ engine was installed here. This remarkable 12 foot long stroke engine was built by Harvey’s of Hayle for Fowey Consols. From there it was moved to Par Consols, before being installed at New Pembroke in 1869.  That was not its final resting place for in 1879:

The very last, though not the least, mining work on which he was engaged was the taking down of an 80″ engine at New Pembroke, making good all the repairs, and refixing, with other additional machinery, at the Great Holiday(sic) Mines Flintshire”.

Crinnis

This mine was originally known as Crinnins Cliff Mine which dated from 1811. It rapidly became a large producer of copper, 10,000 in 1812 and 40,000 by 1816, and all at shallow depths. This spectacular performance encouraged an influx of investment into the area, its copper reserves proved that significant amounts of ore could be found in the eastern half of Cornwall.

 Unfortunately it quickly exhausted its reserves , its mining boom was short lived. It  closed temporarily in about 1833, and reopened again in 1854 as Great Crinnis. After another closure it ended its life in the late 1870s as Great Crinnis and Carlyon Consols.

To the East

This John Taylor controlled mining district had a rival to the east. As the coastline turned towards Par Harbour it entered was Jospeh Austen’s ( latet Treffry) domain. Austen was an industrialist whose business empire in many way’s resembled Taylor’s. He also had canals and railway’s built, he also owned many mines, and he also used heavy investment in technology.

wpid-westcover.jpgAusten and Taylor’s rivalry found outlet in the arena of the battle of the duties. This was the drive to produce the best performing steam engine, a battle which Taylor was at the fore with his consolidated engines. Austen was determined to own an engine that would 51tRtgzctrL__SL160_PIsitb-sticker-arrow-dp,TopRight,12,-18_SH30_OU02_AA160_out perform any of Taylor’s. From this desire William West’s famous ‘Austin’s’ engine was born……but that is of course another story.

John Taylor’s Railway- The Redruth and Chacewater

A quick detour now mining history and steam engines into railways. And this post covers a fascinating railway, and one that provides a walking route through some of the most amazing historical  industrial landscapes in Cornwall.

This railway was driven through some of the richest copper  mining ground in the world. As it did it fed the

RandChacewaterRedruth

The Redruth Terminus

mines with the coal their hungry engines demanded, and took away the rich ore bound for the smelting furnaces of South Wales.

 

Taylor saw beyond the shafts and dressing floors of his mine to the supporting infrastructure. Heavy investment in this infrastructure often formed a  part of John Taylor’s mining strategy. At Wheal Friendship it resulted in the Tavistock Canal, and Consolidated instigated  the Redruth and Chacewater Railway.

In June 1824 the act was laid. A company was formed by John Taylor’s London associates with capital £22,500.By 1825 more then nine miles were operating. The line was 4ft gauge, and originally horse drawn.  Steam was introduced in 1854.

Coal and ore was its main traffic main traffic. Its route linked the sheltered inland port of Devoran with the very heart of the Cornish copper mining district.

“The main line of this railway commences at the extensive tin works on the east side of the town of Redruth, whence it takes a south-easterly course round the mountain of Cam Marth; thence north-easterly by Carrarath to Twelve Heads, whence it takes a south-eastward course by Nangiles and Carnon Gate to Point Quay, situate on an estuary branching out of Carreg Road. Its length is nine miles, two furlongs and four chains; in the first mile and seven chains of which, to Wheel Beauchamp, there is a rise of 103 feet; from thence to its termination it is one gradual inclination with a fall of 555 feet to high-water-mark. From Carnon Gate there is a branch to Narrabo of one mile one furlong; another branch from Nangiles to Wheel Fortune of three furlongs and five chains; another from Twelve Heads to Wheel Bissey, two miles, two furlongs and five chains in length; and another from Wheel Beauchamp to Wheel Buller, of two furlongs four chains in length. The total length of main line and branches is thirteen miles, three furlongs and eight chains.”

From  A Historical Account of the Navigable Rivers, Canals, and Railways, of Great Britain by Joseph Priestley 1831

Taylor achieved far more then just securing an export route for his ore with this railway, he had also won another crucial battle with his war against the William’s family. The Scorrier dynasty had secured a strangle hold over the mines in the area with their Portreath Tramway. They had pushed the limits of their near transport  monopoly with their tramway, squeezing the mines has hard as they could, and given preferential treatment for their own traffic. Taylor had smashed that monopoly with this railway, his line not only served a far less weather dependent port but also was a public carrier. This latter feature resulted in fairer rates for its users. Williams profited, the local mines profited and the William’s lost out.

1870SymonsCliffordUtd

1870 Brenton Symons’ map of Clifford Amalgamated Mines

The line was a success, reducing costs for mine and made large profits. John retained control for the rest of his life. After 1850 son Richard took over. This was another of Taylor’s successes.

The fortunes of the Redruth and Chacewater was inevitably tide in with those of the copper mines, as the declined so the railway’s traffic. It’s death was hastened by the arrival of the GWR,  and the final train ran in 1915 down to Devoran Quay. Although the line is silent today it still serves a valuable purpose. Its network of tracks that impregnated into every corner of this once rich copper district now provides cycle paths for those wishing to explore the area’s  amazing industrial heritage.

Cornish Engines, Consolidated, Taylor and Woolf

In the history of technological advances there are many players. Some who invent, some who develop and those who exploit. John Taylor’s importance is beyond all of these, and this post will explore his role.

Beam

Alongside the huge financial success of Consolidated mine was some amazing engineering achievements. Here would be erected some of the most impressive machines of the  industrial revolution.

When John Taylor re-opened Consolidated in 1818 he appointed Arthur Woolf has his engineer.  This alliance of Woolf’s and Taylor resulted in Consolidated becoming  central to high pressure steam engine development.

Woolf introduced many important developments to steam engine design at Consolidated, whilst Taylor used the engines to gather data on Cornish engine performance. One of the most significant developments was the introduction of a design of steam valve to work with high pressure steam. This ‘double beat’ valve was an adaption of a valve invented by another Cornish engineer, Joe Hornblower. Woolf’s new valve played a major role in rapid rise in Cornish engine performance. It also provided the concept for West’s and Harvey’s self acting double beat valve, a valve that would transform the water supply industry.

DoubleBeat

Woolf’s valve enabled him to build some some impressive engines at Consols, engineering marvels of their day. Two of them at  90″ diameter were the largest, and most powerful steam engines in the world at that time.

Despite of his success with single cylinder Cornish engines Woolf still believed that his twin cylinder compound  design was superior.

In 1824 Taylor settled the dispute about which design was more efficient by ordering two engines from Woolf, one of each design. These he installed at Wheal Alfred , and then conducted extended trials on the two engines. The single cylinder 90″ (Taylor’s) proved superior, a result that would secure the dominance of the Cornish Engine concept.

In 1827 Taylor’s engine was moved to Consolidated where it was renamed Woolf’s, in honour of the engineer.

When Woolf retired on 1833 his work was taken up by two engineers that he had trained at TaylorsEngineConsols, John Hocking and Michael Loam. This partnership would go on to build for Taylor and Sons, one of Cornwall’s most famous engines, Taylor’s 85″ at United Mines.

There are many giants of steam engineering:  Newcombe, Watt, Trevithick, Hornblower, Woolf, Grose, West, Sims, Hocking  and Loam. Taylor is not amongst those names, but he was closely associated with many of the most important advances. His role was what Roger Burt called a ‘polinator’, or in more modern terminology an ‘enabler.’

Taylor’s influence went beyond his own engineers however, and later posts will explore those influences.

Some additional notes on the engines
One of the 90″ engines at Consolidated was at Bawden’s Shaft on the Wheal Fortune section. Unfortunately, little remains to be seen.Woolf’s shaft is beside the Redruth to Chacewater railway track-bed.  Only scanty remains exist of the 1826 engine house.
Davey’s 80″ engine was one of the best engines on Consolidated, and a high performer. It was designed by Hocking. Remains of two walls still stand.
The ruins of Consolidated Taylor’ s 85″ engine house are still impressive, but this is not the site of the famous Hocking and Loam Taylor’s engine. That lies to the south on the Ale and Cake section of United mines.
United Mines Taylor’s 85″- This engine was renowned for high performance. In its first few years of operation it was the highest performer of Duty in Cornwall, and its entries are the highest in Leans reporter.



 

If the terms Duty and Leans mean nothing, follow this blog as we head towards the Taylor v West Duty battle. Before that however, its a detour down the railway tracks.

John Taylor’s mines -A quick list

Here is a list of mine’s extracted from Roger Burt’s biography of John Taylor. It’s a ‘quick and dirty’  attempt to summarise Taylor’s mining interests, so I am sure its not complete, and not fully verified. I have posted however, as it is a useful reference and shows the scale of his activity. If you have any more mines to add, please comment to the post .

John Taylor and the Consolidated mine in Cornwall

If you are attempting patch together this blog into a biography of John Taylor then this post re-joins the time line in 1818, five years after his move into Welsh lead Mining at Halkyn. On the subject of time, its rapidly approaching my talk at Liskeard on Taylor, so I can not guarantee that all my random pre-talk preparation notes will reach this blog in time. So keep following to see how far I get along the journey before Monday.

‘Consols’ is a name that litters the lists of Devon and Cornish mine names. It was a suffix that promised size, wealth, and  company stability. It was suffix that rarely delivered, its inclusion often being used to enhance the sales of mine  shares.

One mine created this fashion in mine names, a mine whose size and output dwarfed all others in Cornwall, and whose success can be credited to John Taylor.

In 1818 Taylor launched a company to work several large mines near Gwennap in Cornwall under the name of Consolidated Mine. It was an ambitious project, and one that had already defeated the well established mining family of Williams of Scorrier.

The mine had sat in a near idle state since 1811, but Taylor rapidly changed its fortunes around. The scale of his success was massive, and can be best grasped through some of the headline facts:

  • Formed of 100 shares and £65,000 capital.
  • it was the largest copper producer in Cornwall for 20 years.
  • It had a peak workforce of about 3000.
  • It contained 63 miles of levels and shafts.
  • In 1836 it had 8 large pumping engines.
  • Between 1819 and 1858 it produced 442,493 tons of ore, the largest quantity from any single mine in Cornwall.

With success like this, it was no wonder that Taylor became known as the country’s leading mining expert. It was a success based on a combination of heavy investment in technology and astute financial management. A fundamental part of this management was making material contracts subject to open competition, a big advance that ensured investors had direct interest in dividends, not their own self interests in providing supplies.

The success of Consolidated was brought to an end by a toxic  combination of greed  and spite by the Williams family.  In 1836 they forced Taylor off of the sett by ensuring a massive increase in mineral owners dues were imposed during renewal of the lease. Taylor pulled out of Consolidated, but only after also pulling out all his massive amount of stock of ore held underground.

Taylor moved out, the Williams family moved in, and so shortly after did failure. Consolidated never again achieved a fraction of success it did under John Taylor’s management. To add salt into the wounds Taylor went on to obtain huge profits from Consolidated’s neighbor, United Mines, but that is another story.

Consolidated was a very wet mine, a mine demanding much from its engineers to keep dry, and that will be the topic of the next post.


 

Some assorted notes:
The sett had been extensively mined for a long time prior to Taylor’s arrival.
Consolidated was formed in 1780 by the amalgamation of seven mines.
In 1805 the competition of cheap copper caused the mine to close.
In 1839 Taylor obtained United mines
By 1843 United’s production was larger then consolidated’s.
In 1857 United and Consolidated were amalgamated as Clifford Amalgamated.
It closed in 1869.
