80-632: Penydarren is a community and electoral ward in Merthyr Tydfil County Borough in Wales . The area is most notable for being the site of a 1st-century Roman fort , and during the Industrial Revolution it housed Penydarren Ironworks the third largest of the great Merthyr works. Penydarren was also used by Richard Trevithick as the location for his experiments into steam locomotion. The community and ward has
160-600: A barge powered by paddle wheels and several dredgers . Trevithick saw opportunities in London and persuaded his wife and four children reluctantly to join him in 1808 for two and a half years lodging first in Rotherhithe and then in Limehouse . In 1808 Trevithick entered a partnership with Robert Dickinson (businessman) , a West India merchant. Dickinson supported several of Trevithick's patents. The first of these
240-505: A hammer at the Penydarren Ironworks. With the assistance of works engineer Rees Jones, Trevithick mounted the engine on wheels and turned it into a locomotive. In 1803, Trevithick sold the patents for his locomotives to Homfray. Homfray was so impressed with Trevithick's locomotive that he made another bet with Crawshay, this time for 500 guineas (£525), that Trevithick's steam locomotive could haul 10 tons of iron along
320-502: A reaction turbine . In 1811 draining water from the rich silver mines of Cerro de Pasco in Peru at an altitude of 4,330 metres (14,210 ft) posed serious problems for the man in charge, Francisco Uville . The low-pressure condensing engines by Boulton and Watt developed so little power as to be useless at this altitude, and they could not be dismantled into sufficiently small pieces to be transported there along mule tracks. Uville
400-409: A berm of 2.5 metres (8 ft 2 in). If a well recorded by Treharne-James in 1905 was centrally placed within the principia , and a square outline is assumed, then the fort had dimensions of 152 metres (499 ft) across the rampart crests, covering an area of 2.3 hectares (5.7 acres). Flavian pottery confirms the origin of the fort as a wooden structure, replaced in stone around AD 100, with
480-446: A boiler feeding a hollow axle to route the steam to a catherine wheel with two fine- bore steam jets on its circumference. The first wheel was 15 feet (4.6 m) in diameter and a later attempt was 24 feet (7.3 m) in diameter. To get any usable torque , steam had to issue from the nozzles at a very high velocity and in such large volume that it proved not to operate with adequate efficiency. Today this would be recognised as
560-403: A carriage attached. (Note this did not use the expansion of the steam, so-called "expansive working" came later) Trevithick began building his first models of high-pressure (meaning a few atmospheres ) steam engines – first a stationary one and subsequently one attached to a road carriage. A double-acting cylinder was used, with steam distribution by means of a four-way valve . Exhaust steam
640-471: A condensing engine. He was not the first to think of so-called "strong steam" or steam of about 30 psi (210 kPa). William Murdoch had developed and demonstrated a model steam carriage, initially in 1784, and demonstrated it to Trevithick at his request in 1794. In fact, Trevithick lived next door to Murdoch in Redruth in 1797 and 1798. Oliver Evans in the U.S. had also concerned himself with
720-598: A consultant on mining methods. The government granted him certain mining rights and he found mining areas, but did not have the funds to develop them, with the exception of a copper and silver mine at Caxatambo . After a time serving in the army of Simon Bolivar he returned to Caxatambo but due to the unsettled state of the country and presence of the Spanish army he was forced to leave the area and abandon £5,000 worth of ore ready to ship. Uville died in 1818 and Trevithick soon returned to Cerro de Pasco to continue mining. However,
800-418: A distance of 9.75 miles (15.69 km). On 21 February 1804, amid great interest from the public, it successfully carried 10 tons of iron, five wagons and 70 men the full distance in 4 hours and 5 minutes, at an average speed of approximately 2.4 mph (3.9 km/h). As well as Homfray, Crawshay and the passengers, other witnesses included Mr. Giddy , a respected patron of Trevithick, and an "engineer from
880-588: A key role in the Merthyr Rising . On 2 June 1831, while local employers and magistrates were holding a meeting with the High Sheriff of Glamorgan at the Castle Inn, a group led by Lewsyn yr Heliwr (also known as Lewis Lewis) marched there to demand a reduction in the price of bread and an increase in their wages. The demands were rejected, and after being advised to return to their homes, attacked

In August 1807, he began driving a small pilot tunnel or driftway 5 feet (1.5 m) high tapering from 2 feet 6 inches (0.76 m) at the top to 3 feet (0.91 m) at the bottom. By 23 December, after it had progressed 950 feet (290 m), progress was delayed after a sudden inrush of water; and only one month later on 26 January 1808, at 1,040 feet (320 m),
1040-545: A meal of roast goose and drinks. Meanwhile, the water boiled off, the engine overheated and the machine burned, destroying it. Trevithick did not consider this a serious setback, but rather operator error. In 1802 Trevithick took out a patent for his high-pressure steam engine. To prove his ideas, he built a stationary engine at the Coalbrookdale Company's works in Shropshire in 1802, forcing water to
1120-488: A measured height to measure the work done . The engine ran at forty piston strokes a minute, with an unprecedented boiler pressure of 145 psi (1,000 kPa). In 1802 the Coalbrookdale Company in Shropshire built a rail locomotive for him, but little is known about it, including whether or not it actually ran. The death of a company workman in an accident involving the engine is said to have caused
1200-522: A more serious inrush occurred. The tunnel was flooded; Trevithick, being the last to leave, was nearly drowned. Clay was dumped on the river bed to seal the hole, and the tunnel was drained, but mining was now more difficult. Progress stalled, and a few of the directors attempted to discredit Trevithick, but the quality of his work was eventually upheld by two colliery engineers from the North of England. Despite suggesting various building techniques to complete
1280-461: A new locomotive called Catch Me Who Can , built for him by John Hazledine and John Urpeth Rastrick at Bridgnorth in Shropshire , and named by Davies Giddy 's daughter. The configuration differed from the previous locomotives in that the cylinder was mounted vertically and drove a pair of wheels directly without a flywheel or gearing. This was probably Trevithick's fourth locomotive, after those used at Coalbrookdale, Pen-y-darren ironworks, and
1360-652: A population of 5,253, increasing to 5,419 at the 2011 Census. Penydarren Park , the site of the Roman fort and the football ground, is today outside the community boundary. Being located on a spur of land 700 feet (210 m) above sea level, just southwest of the River Taff , made Pen-y-Darren an ideal location to build an occupation outpost fort for the Romans in AD75, during the governorship of Sextus Julius Frontinus . It
1440-513: A single internal fire tube or flue passing horizontally through the middle. Hot exhaust gases from the fire passed through the flue thus increasing the surface area heating the water and improving efficiency. These types were installed in the Boulton and Watt pumping engines at Dolcoath and more than doubled their efficiency. Again in 1812, he installed a new 'high-pressure' experimental condensing steam engine at Wheal Prosper. This became known as
1520-613: Is a division of land in Wales that forms the lowest tier of local government in Wales . Welsh communities are analogous to civil parishes in England but, unlike English parishes, communities cover the whole of Wales. There are 878 communities in Wales. Until 1974 Wales was divided into civil parishes . These were abolished by section 20 (6) of the Local Government Act 1972 , and replaced by communities by section 27 of
1600-613: The Cornish engine , and was the most efficient in the world at that time. Other Cornish engineers contributed to its development but Trevithick's work was predominant. In the same year he installed another high-pressure engine, though non-condensing, in a threshing machine at the Trewithen Estate, a farm in Probus, Cornwall . It was very successful and proved to be cheaper to run than the horses it replaced. In use for 70 years, it

Richard Trevithick Richard Trevithick (13 April 1771 – 22 April 1833) was a British inventor and mining engineer . The son of a mining captain, and born in the mining heartland of Cornwall , Trevithick was immersed in mining and engineering from an early age. He was an early pioneer of steam-powered road and rail transport, and his most significant contributions were

Amid great interest from the public, on 21 February 1804 it successfully carried 11.24 tons of coal, five wagons and 70 men over
1840-415: The axles were mounted directly on the boiler, with no frame. On the drawing, the piston-rod, guide-bars and cross-head are located directly above the firebox door, thus making the engine extremely dangerous to fire while moving. Furthermore, the first drawing by Daniel Shute indicates that the locomotive ran on a plateway with a track gauge of 3 ft ( 914 mm ). This is the drawing used as

The latest pottery recovered is Trajanic , confirming that the site was abandoned in the Hadrianic period, with its garrison, moved to a new build fort at Gelligaer . After Samuel Homfray came to South Wales, and establishing the Penydarren Ironworks , he won a bet with Richard Crawshay , and with
2000-434: The gradient was sufficiently gentle, it was possible to successfully haul heavy carriages along a smooth iron road using the adhesive weight alone of a suitably heavy and powerful steam locomotive. Trevithick's was probably the first to do so; but some of the short cast iron plates of the tramroad broke under the locomotive, because they were intended only to support the lighter axle load of horse-drawn wagons. Consequently,
2080-479: The Crown . In Wales, all town councils are community councils. There are now three communities with city status: Bangor , St Asaph and St Davids . The chair of a town council or city council will usually have the title mayor (Welsh: maer ). However, not every community has a council. In communities with populations too small to sustain a full community council, community meetings may be established. The communities in
2160-609: The Government". The engineer from the government was probably a safety inspector, who would have been particularly interested in the boiler's ability to withstand high steam pressures. The configuration of the Pen-y-Darren engine differed from the Coalbrookdale engine. The cylinder was moved to the other end of the boiler so that the fire door was out of the way of the moving parts. That obviously also involved putting

The site in Bloomsbury has recently been identified archaeologically as that occupied by the Chadwick Building , part of University College London . Admission to the "steam circus" was one shilling including a ride and it was intended to show that rail travel was faster than by horse. This venture also suffered from weak tracks and public interest

2560-663: The age of 19 at the East Stray Park Mine. He was enthusiastic and quickly gained the status of a consultant , unusual for such a young person. He was popular with the miners because of the respect they had for his father. In 1797 Trevithick married Jane Harvey of Hayle . They raised 6 children: Jane's father, John Harvey , formerly a blacksmith from Carnhell Green , formed the local foundry , Harveys of Hayle . His company became famous worldwide for building huge stationary "beam" engines for pumping water, usually from mines. Up to this time such steam engines were of
2640-557: The basis of all images and replicas of the later "Pen-y-darren" locomotive, as no plans for that locomotive have survived. The Puffing Devil was unable to maintain sufficient steam pressure for long periods, and would have been of little practical use. He built another steam-powered road vehicle in 1803, called the London Steam Carriage , which attracted much attention from the public and press when he drove it that year in London from Holborn to Paddington and back. It

In 1802 Trevithick built one of his high-pressure steam engines to drive a hammer at the Penydarren Ironworks in Merthyr Tydfil , Mid Glamorgan . With the assistance of Rees Jones, an employee of the iron works, and under the supervision of Samuel Homfray,

To date, the only known information about it comes from a drawing preserved at the Science Museum, London , together with a letter written by Trevithick to his friend Davies Giddy . The design incorporated a single horizontal cylinder enclosed in a return-flue boiler . A flywheel drove the wheels on one side through spur gears , and
3040-646: The concept, but there is no indication that his ideas had ever come to Trevithick's attention. Independently of this, Arthur Woolf was experimenting with higher pressures whilst working as the Chief Engineer of the Griffin Brewery (proprietors Meux and Reid). This was an Engine designed by Hornblower and Maberly, and the proprietors were keen to have the best steam engine in London. Around 1796, Woolf believed he could save substantial amounts of coal consumption. According to his son Francis, Trevithick
3120-542: The condensing or atmospheric type, originally invented by Thomas Newcomen in 1712, which also became known as low-pressure engines. James Watt , on behalf of his partnership with Matthew Boulton , held a number of patents for improving the efficiency of Newcomen's engine—including the "separate condenser patent", which proved the most contentious. Trevithick became engineer at the Ding Dong Mine in 1797, and there (in conjunction with Edward Bull ) he pioneered
3200-444: The crankshaft at the chimney end. The locomotive comprised a boiler with a single return flue mounted on a four-wheel frame. At one end, a single cylinder , with very long stroke, was mounted partly in the boiler, and a piston rod crosshead ran out along a slidebar, an arrangement that looked like a giant trombone. There was only one cylinder, which was coupled to a large flywheel mounted on one side. The rotational inertia of

Trevithick's suggestion of a submerged tube approach was successfully implemented for the first time across the Detroit River between Michigan in the United States and Ontario in Canada with the construction of the Michigan Central Railway Tunnel , under the engineering supervision of The New York Central Railway's engineering vice president, William J Wilgus . Construction began in 1903 and

From the combination of these works, it is presently estimated that the fort had a turf and clay rampart 8.2 metres (27 ft) wide, set on a cobble foundation and separated by a narrow berm of 0.6 metres (2 ft 0 in) wide from its double ditch. The inner ditch was 0.4 metres (1 ft 4 in) wide, the outer 0.3 metres (1 ft 0 in) wide, separated by
3440-589: The development of the first high-pressure steam engine and the first working railway steam locomotive . The world's first locomotive-hauled railway journey took place on 21 February 1804, when Trevithick's unnamed steam locomotive hauled a train along the tramway of the Penydarren Ironworks , in Merthyr Tydfil , Wales. Turning his interests abroad Trevithick also worked as a mining consultant in Peru and later explored parts of Costa Rica . Throughout his professional career he went through many ups and downs and at one point faced financial ruin, also suffering from

By 1910, the Edwardian Baroque YMCA and the Masonic Temple had been completed, and post World War I Penydarren had become Merthyr Tydfil's premier middle-class suburb, with the addition of further terraces north and south of Dane Street, and properties along the Grove. Penydarren was an electoral ward to Mid Glamorgan County Council from 1973 to 1996. Penydarren has subsequently become an electoral ward (coterminous with
3600-418: The flywheel would even out the movement that was transmitted to a central cog-wheel that was, in turn connected to the driving wheels. It used a high-pressure cylinder without a condenser. The exhaust steam was sent up the chimney, which assisted the draught through the fire, increasing the efficiency of the engine even more. The bet was won. Despite many people's doubts, it had been shown that, provided that

As well as Homfray, Crawshay, and the passengers, other witnesses included Mr. Giddy, a respected patron of Trevithick, and an 'engineer from the Government'. The latter was probably a safety inspector, who would have been particularly interested in the boiler's ability to withstand high steam pressures. In modern Merthyr, behind

He was very tall for the era at 6 ft 2 in (1.88 m), as well as athletic and concentrated more on sport than schoolwork. Sent to the village school at Camborne, he did not take much advantage of the education provided; one of his school masters described him as "a disobedient, slow, obstinate, spoiled boy, frequently absent and very inattentive". An exception
3840-401: The incident was exploited relentlessly by James Watt and Matthew Boulton ( competitors and promoters of the low-pressure engine) who highlighted the perceived risks of using high-pressure steam. Trevithick's response was to incorporate two safety valves into future designs, only one of which could be adjusted by the operator. The adjustable valve comprised a disc covering a small hole at

After a protracted struggle in which hundreds sustained an injury, some fatal, the Highlanders were compelled to withdraw to Penydarren House and abandon the town to the rioters. For eight days, Penydarren House was the sole refuge of authority in the district. Forman offered

The Penydarren Ironworks had been financed by William Forman of the Tower of London , who provided all the capital, partly on mortgage but also by taking shares himself. Samuel Homfray left the business in 1813, selling both the house and his shares in the Penydarren Ironworks to Foreman. The house played

The first successful tunnel under the Thames was started by Sir Marc Isambard Brunel in 1823, 0.75 miles (1,200 m) upstream, assisted by his son Isambard Kingdom Brunel (who also nearly died in a tunnel collapse). Marc Brunel finally completed it in 1843,

Unlike in England, where unparished areas exist, no part of Wales is outside a community, even in urban areas . Most, but not all, communities are administered by community councils , which are equivalent to English parish councils in terms of their powers and the way they operate. Welsh community councils may call themselves town councils unilaterally and may have city status granted by

On 20 October 1816 Trevithick left Penzance on the whaler ship Asp accompanied by a lawyer named Page and a boilermaker bound for Peru. He was received by Uville with honour initially but relations soon broke down and Trevithick left in disgust at the accusations directed at him. He travelled widely in Peru acting as

By September, he had recovered sufficiently to travel back to Cornwall by ship, and in February 1811 he and Dickinson were declared bankrupt . They were not discharged until 1814, Trevithick having paid off most of the partnership debts from his own funds. In about 1812 Trevithick designed the ‘ Cornish boiler ’. These were horizontal, cylindrical boilers with
4720-421: The strong rivalry of many mining and steam engineers of the day. During the prime of his career he was a well-known and highly respected figure in mining and engineering, but near the end of his life he fell out of the public eye. Trevithick was extremely strong and was a champion Cornish wrestler . Richard Trevithick was born at Tregajorran (in the parish of Illogan ), between Camborne and Redruth , in

These were sent to John Whitfield at Gateshead, Trevithick's agent, who in 1804 built what was probably the first locomotive to have flanged wheels. Blackett was using wooden rails for his tramway and, once again, Trevithick's machine was to prove too heavy for its track. In 1808 Trevithick publicised his steam railway locomotive expertise by building
4880-445: The top of the boiler above the water level in the steam chest. The force exerted by the steam pressure was equalised by an opposite force created by a weight attached to a pivoted lever. The position of the weight on the lever was adjustable thus allowing the operator to set the maximum steam pressure. Trevithick also added a fusible plug of lead, positioned in the boiler just below the minimum safe water level. Under normal operation

As of the 2001 United Kingdom census , there were 869 communities in Wales. 84 percent, or more than 730, have a council. They vary in size from Rhayader with an area of 13,945 hectares (34,460 acres) to Cefn Fforest with an area of 64 hectares (160 acres). They ranged in population from Barry with 45,053 recorded inhabitants to Baglan Bay with no permanent residents. The twenty-two principal area councils are required to review

Boulton & Watt served an injunction on him at Ding Dong, and posted it "on the minestuffs" and "most likely on the door" of the Count (Account) House which, although now a ruin, is the only surviving building from Trevithick's time there. He also experimented with

If the water ran low, it exposed the lead plug, and the cooling effect of the water was lost. The temperature would then rise sufficiently to melt the lead, releasing steam into the fire, reducing the boiler pressure and providing an audible alarm in sufficient time for the operator to damp the fire, and let

While the site of the Ironworks was left to decay, eventually becoming the service depot of the Merthyr tramway, from 1870, parts of the estate were sold off for housing development. For the period 1876 to 1888, the family leased the house out to

Trevithick was the son of mine "captain" Richard Trevithick (1735–1797) and of miner's daughter Ann Teague (died 1810). As a child he would watch steam engines pump water from the deep tin and copper mines in Cornwall. For a time he was a neighbour of William Murdoch , the steam carriage pioneer, and would have been influenced by Murdoch’s experiments with steam-powered road locomotion. Trevithick first went to work at

Trevithick went on to research other projects to exploit his high-pressure steam engines: boring brass for cannon manufacture, stone crushing, rolling mills, forge hammers, blast furnace blowers as well as the traditional mining applications. He also built
5520-519: Was during this period that he subdued the Silures and other hostile tribes of Wales by establishing a new base at Caerleon or Isca Augusta for Legio II Augusta , and this was one of a network of smaller forts fifteen to twenty kilometres apart for his auxiliary units. The only information known about the fort is from the later excavations undertaken during the construction of the football stadium in 1905 by Frank Treharne-James , and in 1957 during
5600-476: Was limited. Trevithick was disappointed by the response and designed no more railway locomotives. It was not until 1812 that twin-cylinder steam locomotives, built by Matthew Murray in Holbeck , successfully started replacing horses for hauling coal wagons on the edge railed , rack and pinion Middleton Railway from Middleton colliery to Leeds , West Yorkshire . Robert Vazie , another Cornish engineer,
5680-531: Was requisitioned by the UK Government at the start of World War II , it was handed over to the Ministry of Works in 1943. The house was demolished in 1957, and after a period of archeological excavation of the Roman fort, the site was redeveloped as the present day housing community. In 1802, Homfray commissioned engineer Richard Trevithick to build built one of his high-pressure steam engines to drive
5760-598: Was selected by the Thames Archway Company in 1805 to drive a tunnel under the River Thames at Rotherhithe . Vazie encountered serious problems with water influx, and had got no further than sinking the end shafts when the directors called in Trevithick for consultation. The directors agreed to pay Trevithick £1000 (the equivalent of £100,528 in 2023 ) if he could successfully complete the tunnel,
5840-464: Was sent to England to investigate using Trevithick's high-pressure steam engine. He bought one for 20 guineas, transported it back and found it to work quite satisfactorily. In 1813 Uville set sail again for England and, having fallen ill on the way, broke his journey via Jamaica . When he had recovered he boarded the Falmouth packet ship 'Fox' coincidentally with one of Trevithick's cousins on board
5920-556: Was set up at Limehouse to manufacture them, employing three men. The tanks were also used to raise sunken wrecks by placing them under the wreck and creating buoyancy by pumping them full of air. In 1810 a wreck near Margate was raised in this way but there was a dispute over payment and Trevithick was driven to cut the lashings loose and let it sink again. In 1809, Trevithick worked on various ideas on improvements for ships: iron floating docks, iron ships, telescopic iron masts, improved ship structures, iron buoys and using heat from
6000-530: Was the Nautical Labourer ; a steam tug with a floating crane propelled by paddle wheels. However, it did not meet the fire regulations for the docks, and the Society of Coal Whippers, worried about losing their livelihood, even threatened the life of Trevithick. Another patent was for the installation of iron tanks in ships for storage of cargo and water instead of in wooden casks . A small works
6080-411: Was the first to make high-pressure steam work in England in 1799, although other sources say he had invented his first high-pressure engine by 1797. Not only would a high-pressure steam engine eliminate the condenser, but it would allow the use of a smaller cylinder, saving space and weight. He reasoned that his engine could now be more compact, lighter, and small enough to carry its own weight even with
6160-444: Was then retired to an exhibit at the Science Museum . In 2023, the owners of the Trewithen Estate planned to redevelop their farm, which will also involve returning the historic Trevithick steam engine to its original location within the farm. In one of Trevithick's more unusual projects, he attempted to build a 'recoil engine' similar to the aeolipile described by Hero of Alexandria in about AD 50. Trevithick's engine comprised
6240-437: Was uncomfortable for passengers and proved more expensive to run than a horse-drawn carriage, and was abandoned. In 1831, Trevithick gave evidence to a Parliamentary select committee on steam carriages. Also in 1803, one of Trevithick's stationary pumping engines in use at Greenwich exploded, killing four men. Although Trevithick considered the explosion to be caused by a case of careless operation rather than design error,
6320-741: Was vented via a vertical pipe or chimney straight into the atmosphere, thus avoiding a condenser and any possible infringements of Watt's patent. The linear motion was directly converted into circular motion via a crank instead of using a more cumbersome beam. Trevithick built a full-size steam road locomotive in 1801, on a site near present-day Fore Street in Camborne. (A steam wagon built in 1770 by Nicolas-Joseph Cugnot may have an earlier claim.) Trevithick named his carriage Puffing Devil and on Christmas Eve that year, he demonstrated it by successfully carrying six passengers up Fore Street and then continuing on up Camborne Hill, from Camborne Cross, to
6400-568: Was waited on by servants who were dressed in a scarlet and buff livery, while he was driven everywhere in a coach and four horses. In 1800, Homfray married Jane Morgan, daughter of Sir Charles Morgan, 1st Baronet of Tredegar House , and thus obtained a favorable lease of mineral land at Tredegar , where he established the Tredegar Ironworks . In 1813 he was appointed High Sheriff of Monmouthshire and in 1818, returned as Member of Parliament for Stafford borough. Penydarren House
