Coldharbour Mill Working Wool Museum


Coldharbour Mill, near the village of Uffculme in Devon, England, is one of the oldest woollen textile mills in the world, having been in continuous production since 1797. The mill was one of a number owned by Fox Brothers, and is designated by English Heritage as a Grade II* listed building.

Location

Coldharbour Mill can be found just off junction 27 of the M5 motorway near the village of Uffculme, and near to the border with Somerset. The headquarters for the mill was at Tonedale in Wellington. The water provided by the nearby River Culm was a prime factor in Thomas Fox's decision to purchase the existing grist mill. In 1797 he wrote to his brother "I have purchased the premises at Uffculme for eleven hundred guineas, which I do not think dear as they include about fifteen acres of very fine meadow land. The buildings are but middling, but the stream good."
The roads in the area at the time were very poor, and finished cloth had to be carried by pack horses to the nearby ports of Topsham and Exeter, or by carrier's cart to Bridgwater, Bristol and London.

History

It appears that there has been a mill of some description near the Coldharbour site since Saxon times. The Domesday Book recording two mills in the Uffculme area.
At its peak the company employed approximately 5,000 people and owned and operated nine mills and factories in Somerset, Devon, and Oxfordshire. One of the most notable satellite mills was that of William Bliss & Sons, built in 1872 after a disastrous fire in the original mill. Located in Chipping Norton, the William Bliss site was one of the grandest mills in England, complete with reading room, chapel and workers cottages. Fox Brothers bought it in 1920.
The main Tonedale site in Wellington was the largest integrated mill site in the South West of England, covering 10 acres of land and forming the hub of the Fox Brothers woollen manufacturing 'empire'. It is believed to have been the only 'Twin Vertical Woollen Factory' in the world - that is, making both worsted and woollen products, and controlling the entire process from fleece to finished cloth in-house.

The founders

The ancestors of the mill owners, the Fox family and the Were family, were early Quaker converts. During George Fox's first visit to Devonshire in 1655, he went to the house of Nicholas Tripe and his wife, who became 'convinced'. Their daughter, Anstice, married George Croker of Plymouth, and they were much persecuted for their beliefs. Their daughter Tabitha married Francis Fox of St. Germans, Cornwall, a serge maker. The family remained in Cornwall, becoming merchants and shipping agents, and in 1745 the grandson of Francis and Tabitha, Edward Fox of Eggeshall near Wadebridge, married Anne Were, the daughter of a Wellington sergemaker, Thomas Were.. Thomas Were was a very successful manufacturer, and had inherited the WRE trademark, which certified the quality of his cloth. His great-great grandfather John Were of Pinksmoor was credited with owning a fulling mill. During one of the visits of Edward to his father-in-law, it was suggested that one of Edward and Anne's sons should join the Wellington woollen manufacturing business. After four years study overseas, Edward's son Thomas Fox moved to Wellington, and became a partner of Were and Company in 1772, aged 25. Thomas and his wife Sarah Smith, built in 1801, then lived in, Tone Dale House, Wellington - the house is still lived in by a Fox, five generations later, by Ben and Victoria Fox. In 1826, when his sons were partners, the business was renamed Fox Brothers.
The family were prominent in local affairs, and subscribed £1,044 5s 6d in shares in the Grand Western Canal between 1809 and 1813, Thomas having considered the original proposal of 1792 with considerable reticence: "People hereaway seem now as much too eager to engage in Canals as they have been too backward for many years. The almost incredible sum of £900,000 was lately subscribed at Wells in about two hours for cutting one from Taunton to Bristol. Whilst this delyrium continues the writer is neither disposed to subscribe himself nor to recommend his friends doing it, as he doubts whilst such money pours in on them in such abundance it may be badly husbanded."

Banking

In 1787, Were and Company ran short of ready cash, and decided to print their own bank notes - effectively "promises to pay". On 30 October, Thomas printed 500 notes of five guineas each. The notes were well received by local businesses. In 1797, an invasion scare resulted in a shortage of gold and cash, and Thomas Fox issued 3,000 five guinea notes, and seventy six £20 notes in order to enable his business to continue its expansion.
The Fox, Fowler and Company bank eventually had over fifty branches in the West Country, and was authorised to issue its own bank notes until 1921, the year it was taken over by Lloyd's Bank - itself founded by a Quaker, Sampson Lloyd. One of the original £5 notes is on display at Tone Dale House, the family home which Thomas Fox built, in 1801.

Textile products

Exeter was the centre of the mediaeval woollen trade in England, with cloth being exported to the Continental markets of France, Holland and Germany. Kersey, a sturdy cloth, was superseded by serge, so that by 1681 95% of the Exeter cloth export was serge. As already mentioned, the Were family were major suppliers of serge cloth to the Continent, especially Holland. Whilst using the ports of London and Bristol as well, Topsham was a major port for the Were export trade. We have a contemporary description of the Exeter trade in serge by Celia Fiennes :
However, the French Revolution and the invasion of Flanders in 1793 caused very serious difficulties for Exeter cloth merchants, and in 1794 the Weres were forced to cancel major worsted yarn orders.
Napoleon's Italian campaigns of 1796-7 closed the Italian market for English cloth, and then Spain entered the war as an ally of France, leading to the confiscation of Exeter cloth. Only six vessels cleared from the Exe with cloth in 1797, and two in 1798; a far cry from the 1768 despatch of 330,414 pieces of cloth. Some Exeter merchants, such as Barings, moved to London - the Weres changed production to long ells, a fine white serge, for the East India Company. A letter from Thomas Fox to Green and Walford, factors, is to be found in the Fox Brothers Letter Book archive:
With the termination of the monopoly of the East India Company's charter in 1833 through the Government of India Act 1833, the trade in long ells to China declined, and Thomas Fox developed the production of flannel, which was sold in the home market and to America. Following his Quaker beliefs, Thomas Fox refused to sell flannel to the East India Company when he heard it would be used in the manufacture of cartridges.
In 1881, as a result of losses in the First Boer War, a Parliamentary Commission sought to equip the army with khaki uniform. Fox Brothers decided to bid for the contract, reasoning that the new contract for 5,000 puttees would save lives, as well as create employment. Fox Brothers went on to be the major producer of puttees, manufacturing some 850 miles of the cloth in World War One.
In support of the flannel emphasis, in 1865 Coldharbour Mill moved over to producing worsted yarn rather than woollen yarn. This necessitated the need for more power to drive new combing machines.
Coldharbour Mill classifies itself as "a working wool museum" and as such runs its museum machinery to demonstrate how woollen products were made. The demonstration products are made available for sale. The mill has four registered tartans - Devon Original, Devon Companion, Somerset, and Blackdown Hills.

Architecture

English Heritage wrote a Historic Buildings Report about the mill complex, and described the site as "probably one of the best-preserved textile mill complexes in the country. It retains the full range of buildings and power system features which characterised the development of the 19th century textile mill with much of the machinery that was used at the site in the 20th century."
Coldharbour Mill was primarily always used for the production of wool yarn for the weaving frames of the Wellington mill. The original grist mill was probably a three storey building, and the original sale notice of 1788 states "The Stream divides in two Parts, one at each End of the House, and they are in a Manner two separate Mills, under the same Roof". A legal dispute of 1834 contains a detailed map of the water courses, which are in their existing positions, with a leat to the front and rear of the grist mill.
The foundations of the main mill were mentioned in a letter of 15 April 1799, stating that they were 50 feet from the grist mill - further away than the current building, but at a point where the wall is thicker today. The mill building of 39 feet wide by 123 feet long was very large for its time. Thomas Fox wrote to his machinery supplier describing how the new mill building was to operate:
An inventory of 1802 suggests that spinning was to be carried out on hand-powered spinning jennies, with a waterwheel powering the carding machines. By 1816 the mill contained worsted spinning frames, and in 1822 a new waterwheel costing £1,500 had been installed.
The main mill building was expanded at various times, with a two story extension added to the north; a fireproof stone staircase to the east; a wheelhouse; a fourth floor to the main building; and an adjacent combing shed built over the tail race leat flowing from the waterwheel.
Steam power came to the mill in three major building phases. In 1865 a beam engine house was built, together with a boiler house and the first chimney on the site. In the 1890s a second beam engine arrived, the boiler house was extended and the existing chimney built, and then in 1910 the existing horizontal engine was fitted, the Green's economiser house added and the boiler house extended again.
The mill site contains a wide variety of subsidiary buildings, including stabling, a linhay, a gas retort house, a carpenter's workshop, an air raid shelter from WWII, worker's cottages, and the manager's house. The tail race which takes the water away from the waterwheel is unusual in that it runs under the combing shed in a wide culvert, before briefly reappearing and then running underground again for some 200 metres.

Water power

The English Heritage report states "it is possible that the wheel pit and parts of the wheel itself are the remnants of the new wheel which was recorded in the Stock Book of 1822...and should be considered of considerable historic significance". The cast and wrought iron high breast-shot wheel is 18 feet in diameter by 14 feet wide, with 48 buckets. It is part of a very unusual survival of a combined water and steam powered drive system, as it continued to be used after the 1910 addition of the horizontal steam engine, and the drive mechanism is still in place. The wheel is turning most days.

Steam power

Thomas Fox's brother Edward was part owner of a Cornish mine, and was instrumental in installing an early example of a Boulton and Watt engine. Edward told Thomas about this new technology, with the result that James Watt was invited to Wellington in 1782, just six months after his patent for the sun and planet gear that allowed reciprocating motion. Thomas missed the meeting, but wrote to him afterwards:
However, the visit came to nothing, partly due to the very high cost of coal, and partly due to the discontent about mechanisation, which would culminate in the later Luddite Movement. A letter in 1785 from Thomas states
Thus it was that the first mechanised wool spinning machinery, purchased from Backhouse of Darlington, were powered by horses. These arrived in September 1791, bringing the Industrial Revolution to the West Country. It was evident from a letter of 1786 that Thomas wished he could have had a cheap source of coal, as in those parts of the country fed by canals:
Although the Wellington mill purchased a steam engine for £90 in 1840, Coldharbour Mill did not get a steam engine until 1865, by which time the Bristol and Exeter Railway was supplying cheap coal to Tiverton Junction. The mill has two Lancashire boilers in the boiler house, only one of which is still operational. Initially a 25 hp beam engine was installed, followed by a second beam engine in the 1890s. A Pollit & Wigzell 300 hp, cross compound engine superseded the beam engines in 1910 and continued in use, along with the water wheel, until Fox Brothers closed the mill in April 1981. Today the cross compound steam engine remains fully operational and runs regularly at steam up weekends. It drives the shafting on all five floors of the mill via an operational rope drive. In 1993 a salvaged 1867 Kittoe and Brotherhood beam engine was painstakingly restored and installed at the mill, in one of the disused beam engine sheds.
The mill contains a number of other steam powered exhibits, including a working Ashworth fire pump, already at Coldharbour, but repaired in 1984 with components from Bliss Mill; a very rare example of a low pressure wagon boiler dating from the late 1700s; and a steam powered flue fan.

Electrical power

Coldharbour Mill also had a small water turbine for electricity generation, which used the 14 foot head of water between the upper leat and the tail race. No references have been found to it in any register of Devon hydro-electric schemes, and it was unlikely to have generated any more than 3 kW peak power. The exit is visible today in the tail race leat, but nothing else is believed to exist.
Two generators were installed in the beam engine house after the beam engines were removed and these were driven by the Pollit and Wigzell engine. The flat belt pulley system is still in existence. It is believed that this was used for lighting rather than running the machines.

Gas production

Coldharbour Mill generated its own coal gas on site for lighting the mill. Although the retorts have been removed and disposed of, the Gas Retort house which housed the retort bench is still standing. In fact, the original gas retorts have been discovered in the leat, where they served as weir components. English Heritage classifies the late 19th century Gas Retort House as a very rare survival of gas-making facilities.

Textile machinery

At the time of its closure in April 1981, Coldharbour Mill still had its textile machinery in position. The majority of these machines have been preserved, and have been augmented with weaving machines rescued from the closure of the Tonedale site. The lowest part of the site, the level 1 combing shed, dealt with the initial cleaning and combing of the unwashed wool. The process involved a number of separate stages, each with a specialised machine. The eight opening gill machines opened up the fleeces and prepared the wool for washing in a large back-washer with steam heated rollers. Following the washing, further gill boxes produced successively combed fibres, which were passed to a circular Noble combing machine. This machine separated the fibres into long "Tops" and the short poor quality fibres. Although these machines are preserved on site, they are no longer in use today. British wool tops are purchased in, dyed into standard colours, and then up to ten strands of tops are fed into the Intersecting Gill Box. The gill box starts the process of drawing out the fibres, and also enables new colours to be created by blending together the standard colours. The output of the gill box is termed a sliver. This particular machine has a mechanism to ensure the weight of the sliver is constant, which is important to ensure the final yarn thickness is constant.
The next process is to draw the slivers out further, and to give the fibres a small twist to strengthen the resulting slubbing such that it can be wound onto a bobbin. At Coldharbour Mill, this is demonstrated on a Price Smith and Stells draw box of 1959. The bobbins from this machine are then placed in a further draw box by Prince Smith and Stells, this time an 1898 machine, and the thread from a pair of bobbins is drawn out to a seventh of its diameter, and given a light twist. If this output is to be used for Aran yarn production, it is termed a roving, and is sent on to the spinning frame. However, if the slubbing is for double knitting yarn, the slubbing must go through another reduction on a draw box.

The museum today

The museum is owned and run by a not-for-profit charitable trust, Registered Charity No. 1123386. It has a number of educational programmes for schools including Victorian Drama; Materials & Fibres; and Britain at War.
The mill is home to a number of other exhibits:
