The site of Clintsfield Colliery is remarkable today for the ruin of the 19th-century engine house (SD 6297 6978) built to house a steam beam engine for pumping and for the extensive ground works associated with the operation of a late 18th-century/early 19th-century colliery. Fig 2 shows its present state and a sketch of the engine house’s probable original appearance.

Clintsfield engine house is Grade II listed and the whole field in which is situated is a scheduled historical monument.1 It is located on private land and there is no public access. Images in this article were collected during prearranged visits to the site by Tatham History Society in August 2015.

As a colliery, Clintsfield was one of the many small-scale mining operations of the period which worked thin coals in the Lonsdale Fells Basin.2 It is situated on sloping ground to the south of the River Wenning and railway line between Wennington and Bentham. The field in which it was situated was called ‘Pit Field’ on the Tatham Tithe map of 1848.3

Its survival derives from the fact that there has been no development on the site since the 1860s. The site does not have easy access to public roads or other properties. The surrounding field has not been ploughed and there have been no attempts to fill in the earthworks associated with the colliery. The engine house itself was very well built and any damage and modifications to the walls seem to be associated with its subsequent conversion to a short-lived residence. Despite losing its roof all the other walls remain extant and solid, a tribute to Arthur Burrow, the stone mason who erected it.

Geology

The coal here is interbedded with the Accerhill Sandstone and varies from 16 to 24 inches thick. It lies above the coal horizon worked at the nearby larger Tatham Colliery (Ward's Stone Sandstone) but it was also worked at an outlier of the Smeer Hall Colliery at Stauvin, as well as at collieries further east in the Bentham coalfield.4 The map shows the sandstone outcrop and the interpreted position of the coal at the bedrock surface, i.e. beneath the cover of glacial sediments. The beds dip at around 20 degrees to the NE which would put the shaft depth near the engine house at 70 metres. The area available for working the coal was severely limited by the network of large faults plus any minor ones encountered. These would cut out the coal being followed in the workings and make digging new shafts a risky business. Several of the shafts shown would have failed to find coal.

A second thinner coal underlay the Clintsfield coal in the Silver Hills Sandstone and it was mined in shallow working at Blands, Raby Lodge, Perries & Robert Hall. None of these became an established colliery.

The site was accessible from the west (off a track to Clintsfield farm) and south (via tracks to Greenfold farm and on to Robert Hall) but, as the first OS maps clearly show, at one time also had access to the north via a wooden bridge over the Wenning in the 1840s. This would have provided access to the village of Wennington but, more importantly, to the larger industrial settlements at Low and High Bentham which were important for its closing years. (see below) It had disappeared by the time of the second edition OS map in 1890.

At Clintsfield, 20 pits have been located, with five of these indicated as ‘old’ on the 1847-50 OS map and four, described as just pits, were presumably active (larger red dots), including the beam engine shaft. The remainder are taken from the large scale BGS field maps (1991-92) and personal fieldwork. (The area north of the railway has not been covered by BGS). All the pits were described as ‘old’ in 1890.

The coal would be got from levels driven in the coal, with extraction proceeding up-dip from the levels which also functioned as haulage ways to the pit bottom. A new pit would be dug further down the dip when the old levels were worked out, or reached a fault. The scheduled listing identifies a potential horse gin (wheel) site to the north-west of the engine house marked by the circular trackway. However, only hand-powered windlasses are mentioned in the 1856 sale of the colliery's equipment.5 More detailed descriptions of mining are given in the Tatham History Society website article on ‘Tatham Colliery’.6

There is no indication of the number of men and boys who worked there at its peak. Miners are recorded in both the parish registers from the late 18th century and in the 1841 census of the parish at Bridge End, Sod Hall, Outlay, Millhouses, Moor End, Moorside, Perry Moor and School House, but many of these could have been employed elsewhere in the district. Old cottages at nearby Greenfold farm are reputed to have been miners’ residences; these are now used as farm buildings.

Both registers and the 1841 census are likely to have underestimated the numbers employed in the area, since the registers only recorded the occupations of adult males and the census of 1841 did not consistently report the occupations of women and children. The shallowness of the seams, a maximum of 24 inches (60 centimetres), would have made working conditions very difficult and it is likely that, as at nearby Smeer Hall, children and adolescents were employed in many of the menial tasks, such as dragging baskets or sledges from the coal face to the shaft. It is also possible that other members of the family were employed above ground, as in south Lancashire collieries of that period.

Mineral Owners and Colliery Operators

The exercise of mineral rights on the site remain obscure but would appear to have alternated between the Lords of the superior Manor of Hornby and the Gerards who held the ‘manor or reputed manor’ of Robert Hall which includes, amongst others, Clintsfield and Greenfold farms on which the colliery was located. Hornby Castle operated other mines in Tatham, Farleton and Smeer Hall in Roeburndale. The Gerards were absentee landowners, their main estates being at Ince and around Wigan where they were also involved in mining activities. A settlement of their estates in 1826 refers to the ownership of mineral rights in south Lancashire but does not specifically mention Robert Hall, although if does refer to a corn mill here.7 It would seem, however, that they leased mineral rights from Hornby at various times since on 27 July 1857, after the mine had closed, the Gerards paid Pudsey Dawson, Lord of the Manor of Hornby, for the right to get coal under enfranchised land to September 1856.8

The earliest record of mining at Clintsfield is a lease of 1772, which was renewed in 1782. This was between Lord Charteris, Lord of the Manor of Hornby, and John Martin of Arkholme and John Addinson of Littledale, yeomen, and Edward Martin and William Storrs of Tatham, colliers.9 Land Tax records between 1781 and 1832, however, give the owner of ‘Clintsfield Colliery’ as the Gerards. John Martin & Co were recorded as tenants until 1789 but no names are recorded thereafter.10 It is unclear which pits this partnership operated but it is likely that they were the older pits near the top of the hill. George Smith, the agent for Hornby Castle, kept a diary which in 1822 refers to Arthur Cort of Lowgill paying £20 3s rent to Rev. Procter. This is nothing to support Hudson’s speculation that this related to the colliery at Clintsfield. Cort did meet Smith on 19 November 1832 about Clintsfield but the purpose of his visit is not recorded.11 What is clear is that from May 1834 Cort took a fourteen-year lease on the colliery from the Gerards at £70 pa. His name appeared in the rent book until his death in 1843 but in August 1839, just prior to his becoming bankrupt in November of that year and his estate being put in the hands of administrators, the lease had been transferred to Hornby Roughsedge of Bentham, who was owner of Bentham flax mills and a major landowner in the area.12

George Sergeantson, who operated the Ingleton collieries was approached by Roughsedge to operate Clintsfield in 1842. His account, written later that decade, underlines the reason for Roughsedge’s purchase of the colliery lease.

On the 30th June 1842 I had an interview at the Bridge Inn, Ingleton, with Mr Roughsedge to try to take his colliery at Clints Field, my object was to secure the trade of the Bentham Mill, 500 tons a year. Mr Roughsedge wished me to take the colliery as it stood, with a five years lease paying £70 a year for rent to Mr Gerrard and pay him £2500 for his machinery. This required consideration especially under the depression of trade that existed this year which was unexampled, I believe, in almost every branch...

In August 1844 on my visit to Ingleton I was concerned to hear that the Bentham Mill was about to stop work in consequence of a disagreement of the partners, therefore, I imagined that the Clints Field Colliery, which entirely supplied it; would shortly stop also; most fortunate for me in 1843 that I had not taken it from Mr Roughsedge; had I done so and lost the Bentham Mill trade, it would have been a most serious loss to me...

In June 1845 I took the Clints Field Colliery until the expiration of the Mr Roughsedge’s lease which is about 3½ years more, for £200 a year and Mr R. to take 5000 loads of coal at 8d a load and 1d a load deducted upon an increase of quantity. The Clints Field Colliery was stopped working from that time. Sundry railroads were this year projected in the neighbourhood which some said would be beneficial and others injurious to the colliery; the North Western Colliery (railway?) which was to pass through Ingleton obtained their Act of Parliament in the Session of 1846 and during the panic amongst the railway shares that year, they scarcely ever were at discount. The colliery returns of the year 1845 were the best for many years and the leasing of the Clintsfield Colliery had turned out advantageously much above the rent given for it … 13

Despite Sergeantson’s withdrawal, Hornby Roughsedge would appear to have extended his lease beyond 1848, however, since his name appears in the accounts as paying £80 pa to the Gerards until 1853, but the mine would not seem to be operational during this time since it was reported in 1855 to have been closed for several years due to flooding. His interest in the mine presumably waned when access to railway coal provided a more convenient way of obtaining fuel but in 1850 he sold the Bentham mills to Messrs Waithman & Co. and retired to Fox Ghyll, near Ambleside.

In March 1853 the tenancy was advertised with the option of purchasing all the equipment at valuation.14 Roughsedge would subsequently appear to have removed all his equipment, including the engine, boiler and grate. In November James Wearing Sewart and George Handley, who operated mines to the east of Sedbergh around Garsdale, took the lease for £65 pa. Sewart clearly provided the capital.15 He rented out his home at Sedbergh and moved to Wenning Cottage.16 Over the next eighteen months, Gerards paid for repairs to the colliery and the wooden bridge over the Wenning, and paid Messrs Moore for a new over grate and boiler in the engine house. Gerard also received £5 for ‘dilapidations’ to the colliery from Roughsedge. Sewart purchased a new engine and other equipment and the mine reopened in March 1855 after ‘a great outlay of money’.17

It would appear that the bridge was damaged in the winter of 1855-56 since in December George Moss at Clintsfield farm was given a rent abatement because his men and horses had been used during bridge repairs. This may well account for Sewart’s advert the following month informing his customers of the plentiful supply now available and reducing the prices.18 These prices, however, were still considerably higher than those obtained by Sergeantson a decade earlier.

In March, Sewart paid a year’s rental arrears. The following month trustees were appointed to manage his affairs for the benefit of his creditors: his younger brother Allan, Matthew Cooper Burrow of Guy Hill and James Atkinson of the Marshes.19 In July they sought to find a tenant to take on the lease but failed.20 In September they paid half a year’s rent and closed the mill. In September his properties in Sedbergh and Garsdale were advertised to auction.21 The following month all the equipment was put up for auction in Bentham along with other properties which Sewart had acquired in the area.22

The following year Gerards attempted and failed to find a new tenant. By 1861 the engine house had been converted into a house with additional first floor and hearths and was inhabited by a young agricultural labourer from Wennington and his family.23 There were no inhabitants in subsequent censuses. There were clearly attempts to reopen some of the workings in the Clintsfield area in 1863 and an advert in 1873 implies some working of the upper coal seam continued and that there was a ‘ready demand on the spot’, but it also suggests that it was not being fully exploited.24 However, no rental income is shown in Gerard’s accounts.

Pumping engines and the engine house

Yates' map of Lancashire in 1786 shows four coal pits at Clintsfield and a waterwheel. Since the evidence of field names (Mill Mires and Mill Field) indicates that the Robert Hall corn mill lay further east (but not present in 1786) and, unless Yates’ symbol is misplaced, this has to be considered as a waterwheel gin or pumping engine, as suggested by Hudson.25 There is unambiguous evidence that such engines were had been used in the nearby Ingleton coalfield. A letter to the press in 1872 by George Barker, mining engineer, recalls that ‘Long ago there were gins for pumping the water and horse gins for drawing the coal. The principal gins for drawing the water were at Park-foot and the water for turning the wheels was conveyed by means of a cut from the River Greta at Ingleton".26 They were widely used elsewhere in metal mining areas, including Coniston Copper Mines.27

The simplest means of converting the wheel's rotation to horizontal reversing motion was to have a crank arm on the wheel axis. This was transmitted by a combination of rods and chain to a weighted balance bob at the engine shaft which converted it to the vertical reversing motion of the lift pump rods. An overshot wheel would be the most powerful, but a breast or even undershot could be used.

The location of the wheel is uncertain but Yates shows it close to the River Wenning, with either the river or the tributary beck as the source of the water. The field to the west is named ‘Gin Holme’ on the tithe map of 1848 (no 464) and it likely that this extended further to the east before the bridge and railway were built and cut it in two. Hudson, however, marks the sites of two potential water wheels on hill above and below the present engine house on his map of the colliery and considers that are possible remains extant today, but it has not been possible to confirm this from subsequent fieldwork.28 The flow of the beck today (2015) is clearly insufficient to power such a wheel, and, although members of the family who lived at Clintsfield farm until the 1950s remember it as a much more forceful beck with considerable flows of water, is seems unlikely that would have been sufficient to provide a constant source of power.29

The beam engine housed in the engine house was obviously installed to drain the later workings which would lie well below the water table. Sales of equipment at the colliery invariably refer to pumps. There is no indication that it was also used for raising coal, as such engines did elsewhere. The two small ponds created further upstream on the beck (see map) would have supplied clean cold water to the condenser and the boiler would use that source as well as warm water from the condenser over flow. The contaminated water pumped from the shaft could not be used for these purposes and the embanked pond below the engine house may have been for its storage and passive treatment, e.g. oxygenation and iron oxide precipitation, before release to the river.

The construction of the new engine house is referred to by George Smith in October 1839 when he measured the stone supplied by Arthur Burrow of Blands for masonry work which was carted by Richard Fayrer and Thomas Alderson, tenants of Clintsfield and Greenfold farms.30 The obvious source would have been the sandstone quarry in Bland's front yard shown on the OS map. The new engine house, therefore, was built after Roughsedge had taken over the lease of the colliery in August 1839.

The wooden bridge over the Wenning was probably built at the same time. The accounts for the mid-1830s show that Cort had paid his rent up to six months in arrears and did not pay the rent due in December 1838 until June the following year. The £35 due in May 1839, therefore, would have been paid by Roughsedge but the rental records suggest this was waived since no date of payment is recorded. Instead it was ‘allowed at the same time for Bridge’. There are no earlier references to a bridge. A further £15 was allowed in December 1840. Thereafter, unlike Cort, Roughsedge always paid on time.

Steam beam engines had been in use elsewhere since the early 1700s but the earliest local record of an engine locally is at Tatham Colliery in 1826.31 At least two engines are known to have been deployed at the colliery. Cort had a ‘moiety’ in a 5 hp steam engine and boiler, pump and other apparatus on the site which was advertised for sale in December 1839.32 It seem likely unlikely that Roughsedge bought and installed this in his new engine house, but nothing is known about the engine he did use and which he removed with his other apparatus in 1853/4. A new 25 hp engine was installed in the same year by Sewart.33

The principle of the beam engine is that the weight of the pump rods down the shaft forces the mine water into the bottom of a lift pump through a non-returnable clack valve (such as in a hand pump on a well). This is then raised up by a piston attached to the other end of the beam which is pulled down into a cylinder by a partial vacuum created below the piston by condensing steam to water. In the original Newcomen atmospheric engines from 1712 onwards it was the air pressure which pushed the piston down. Then in 1769, Boulton and Watt added pressure from steam introduced above the piston to improve the down-stroke, as well as increasing the vacuum by removing the condensation from the cylinder to a separate condenser, thus maintaining the temperature of the cylinder and reducing fuel costs. This became the standard single-acting engine. A later modification by Watt assisted the up-stroke of the piston caused by the weight of the pump rods, by introducing steam below the piston at the appropriate moment, i.e. creating a double-acting engine. After the expiry of the Boulton and Watt patent in 1800, many varieties of these engines were produced by others.

The small size of Cort’s 5 hp engine at Clintsfield suggests a very early model, perhaps even a Newcomen, as second-hand ones continued in use in northern collieries. The information on the 25 hp engine is more instructive, suggesting it was a double-acting engine using high-pressure steam. Although built by another firm it is likely to have resembled Boulton and Watt engines of the early 1800s such as the 38 hp engine of 1809 still in working order on the Kennet and Avon canal where it supplies water to the summit stretch.34 Comparison with this suggests the Clintsfield engine probably had a cylinder of about 28 ins diameter, a piston stroke of 7 feet and a tempo of 10 power strokes per minute, i.e. a nod every 6 seconds.

At Clintsfield, the piston would have sat in the main building below the beam where it was supplied with steam by a coal-fired boiler in the end of the adjacent open ended building (surprisingly far from the piston), with the flue gas going up the short chimney. The condenser had to be lower than the piston, possibly in a well now filled in. On this basis an attempt has been made to fit such an engine into the Clintsfield engine house. (fig. 13)

The up-stroke and down-stroke of the piston reflect the opposite strokes of the pump rods. The piston down-stroke is the main steam powered stroke although in the double-acting engine the up-stroke is a lesser power stroke. The valve sequence when the engine is running is operated automatically by rods (plug rods) connected to the beam (not shown) which trigger the various levers actuating the valves.

  1. With the piston at the top of the up-stroke, the inlet is open and high pressure steam fills the cylinder and condenser (valve A & C open, B closed).
  2. Turning the cold water jet on initiates condensation, reducing pressure below the piston and starting the down stroke. Expansion of the steam above the piston aids this (valve C open, B closed and A closed at half down-stroke).
  3. At end of down stroke, steam from above the piston is introduced below it by opening the equilibrium valve (B), so equalising the pressures and aiding the up-stroke as the beam is tilted by the weight of the pump rod (valve C & A closed, B open).

It is likely that at this time the beam was cast iron and the correct movement of the piston rod was achieved by the parallel motion linkage invented by Watt, rather than the curved ends and chain linkages of the earlier wooden beams. There was probably also an air (lift) pump driven by the beam which pumped the spent warm water from the condenser and added it to the boiler supply.

The diameter of the shaft lift pump is not known but if it was only 10 inches then it could be pumping 100 litres per stroke or one cubic metre per minute for a coal consumption of about 15 cwt./day.

Associated structures on the site: the railway and railway cottages

The Leeds-Skipton-Morecambe railway crossed the site to the north which opened on 1 June 1850 and clearly affected the colliery in a number of ways.35 Opinion at the time was divided about whether the railway would open up new markets for local coal, or undermine their operations by importing coal from mines elsewhere. The latter proved to be correct. The railway also cut across the track to the wooden bridge to the north, necessitating the provision of a gated level crossing. The North Western Railway constructed two semi-detached cottages adjacent to the crossing. These housed two families of permanent way workers (plate layers) recorded in the censuses of 1861-1911, but not 1901. In 1891 two of their children were silk workers, presumably at Low Bentham Mill.36 These cottages incorporate unusual triangular bay windows, from which it would have been possible to view both the track to railway from both the river and the colliery. Water supply was obtained from a spring and well in the old river bed behind them, although local residents recall that the inhabitants also brought water along the rail track from Wennington. They also used the railway for pedestrian access.

These cottages were inhabited until the 1950s. They even housed an evacuee during the Second World War. Residents of Clintsfield farm recall that the cottage front gardens were well tended and full of flowers. Today they are abandoned and, without any possibility of public access and amenities being made available, nor prospect of renovation. All remnants of the wooden bridge over the Wenning have disappeared.
