Goldsworthy Gurney

From Wikipedia, the free encyclopedia

Sir Goldsworthy Gurney (1793-1875) was a surgeon, chemist, lecturer, consultant, architect, builder and prototypical British inventor of the Victorian period. Amongst many accomplishments, he discovered the principles underlying limelight; developed a series of the early mechanically powered road vehicles; and laid claim — still discussed and disputed today — to the blastpipe, a key component in the success of steam locomotives, engines, and other coal fired systems.

[edit] Biography

Gurney was born in the village of Treator near Padstow, Cornwall on 14 February 1793. His unusual Christian name was taken from his godmother who was a maid of honour to Queen Charlotte. He was schooled at Truro, where he showed an interest in contemporary sciences; and had the opportunity to see Richard Trevithick's 'Puffing Devil', a full-size steam road carriage, at Camborne.

After his medical education and marriage to Elizabeth Symons, a farmers daughter, in 1814 he settled in Wadebridge, Cornwall practicing as a surgeon, but he also became interested in chemistry and mechanical science.

He moved with his family to London in 1820. There he expanded his scientific knowledge and started giving a series of lectures on the elements of chemical science to the Surrey Institute. He purchased a manufacturing works at Albany Street, near Regent's Park, and proceeded to work on a number of inventions, described below, whilst continuing to practise as a surgeon.

In 1830, Gurney leased a plot of land overlooking Summerleaze Beach in Bude, from his friend Sir Thomas Ackland, and set about the construction of a new house to be built amongst the sand hills. The construction rested on an innovative concrete raft foundation, representing an early worked example of this technique. The original house called "The Castle" still stands but has been extended over the past century. A Bude and Stratton Heritage Trust has been formed and plans are well advanced, under the Limelight Project, to raise funds to interpret the fascinating history and heritage of Bude and the surrounding area, within Bude Castle.

In 1863, Gurney was knighted by Queen Victoria, but later that year suffered a paralytic stroke; he retired back to Cornwall, where he died, apparently penniless, in 1875. He is buried at Launcells near Bude.

[edit] Gurney's steam carriage

In the period 1825–9, Gurney designed and built a number of steam powered road vehicles, amongst the first designed with the intent to commercialise a steam road transport business — the Gurney Steam Carriage Company. His vehicles were built at his Regent's Park Manufactory works, and tested around the park's barrack yard, and on frequent excursions to Hampstead, Highgate, Edgware, Barnet and Stanmore, at speeds of up to 20 miles per hour (32 km/h). Gurney was by no means the only inventor working in this field — Luke Herbert, in his 1837 Practical Treatise on Rail-Roads and Locomotive Engines rebuts in scathing fashion claims made for Gurney in preferece to Trevithick as inventor of the steam carriage:

"…it is a matter of fact, that Gurney's carriages, made in every essential respect after Trevithick's models, did, occasionally, run [on the public roads]; and so did the carriages of many other locomotionalists; some prior, some subsequent to Gurney; some decidedly superior to his, and all those that were inferior, were incapacitated from proceeding beyond preparatory trials, by want of that material with which gentlemen of fortune, then unacquainted with steam locomotion, had so lavishly furnished on Mr. Gurney."

One of his vehicles was sufficiently robust to make a journey in July 1829, two months before the Rainhill Trials, from London to Bath and back, at an average speed for the return journey of 14 miles per hour — including time spend in refuelling and taking on water. His daughter Anna, in a letter to The Times newspaper in December 1875, notes that "I never heard of any accident or injury to anyone with it, except in the fray at Melksham, on the noted journey to Bath, when the fair people set upon it, burnt their fingers, threw stones, and wounded poor Martyn the stoker". The vehicle had to be escorted under guard to Bath to prevent further luddism.

The steam carriage was not a commercial success. There was an understandable apprehension on the part of the public to a conveyance atop a dangerous steam boiler; seeking to overcome this objection, Gurney designed an articulated vehicle, termed the Gurney steam drag, in which a passanger carriage was tethered to and pulled by an engine. At least two of these were built and shipped to Glasgow around 1830. According to the Steam Club of Great Britain:

The first was sent by sea to Leith, but it was damaged in transit. It appears that this carriage was left in Scotland while Gurney returned to London for spares. He gave instructions for it not to be used, but it was transferred to the military barracks where it was steamed and a boiler explosion ensued, severely injuring two people. The second carriage may have run a service for a short time but it remains unclear whether any passengers were carried for money. The local press carried the story of the explosion.

The remains of one of this pair rests in Glasgow Museum of Transport, to which it was presented, having been found in a barn near the Paisley Road. Again, according to the Steam Club of Great Britain, it comprises:

an almost complete chassis with the engine, some pipe work, the valve gear and the steering gear. The wheels, boiler and bodywork are missing. The whole is painted red and this has made photography difficult but appears to have preserved this item, as it is untouched since arriving at the Museum in 1889!

A regular service was established by between Cheltenham and Gloucester by Sir Charles Dance, running four times daily, for a number of months and based on a fleet of three of Gurney's carriages; but the aspirations of Dance and Gurney were effectively dashed, according to Francis Maceroni in his 1836 book A Few Facts Concerning Elementary Locomotion^[1]

The many wealthy horse-coach proprietors, together with the narrow minded country gentlemen and magistrates of the district, who erroneously conceived their interests threatened by the substitution of steam power for horse, formed one of the most disgraceful and mean conspiracies against a national undertaking that can be well remembered. By means of parliamentary intrigue, and false representations, these despicable persons obtained certain local turnpike bills to pass "the Honourable House" establishing tolls on steam carriages, which amounted to a virtual prohibition on their use.

A charge of £2 was levied on each steam carriage journey, whilst the toll for a horsedrawn carriage was 2 shillings. This may be contrasted with a contemporary exchequer loan to the railway developers of £100,000. Maceroni continues:

In addition to this flagrant outrage against justice and utility, the worthy squires and magistrates of the Cheltenham district, suddenly, without any necessity, covered a long tract of the road with a layer of loose gravel, a foot deep, which, adding to the above-mentioned difficulties an impediments, put an entire stop to the undertaking.

At the same time, press coverage of an accident befalling a Glasgow steam drag adversely affected the reputation of the vehicles. Gurney was bankrupted with debts of £232,000.

Sufficient was the concern about Gurney's bankruptcy, and sufficient were his contacts, that a House of Commons select committee was convened from 1831 to 1835 on Mr.Goldsworthy Gurney's Case. Its final report stated:

"Mr Goldsworthy Gurney was the first person to successfully operate steam carriages on common roads, and he took out patents for his invention in 1825 and 1826-27. In 1830 Mr Gurney entered into contracts with various individuals for the commercial exploitation of his invention, carrying passengers at a lower fare than horse carriages. In 1831 more than 50 private bills were passed by Parliament imposing prohibitive tolls on steam carriages (two pounds or more, while horse carriages might pay six shillings or less), and the contractors suspended their operations, pending a petition to Parliament. A select Committee was appointed, and concluded that steam carriages were safe, quick, cheap, and less damaging to roads than horse carriages, that they would be a benefit to the public and the prohibitive tolls should be removed. A bill to this effect was passed by the Commons but rejected by the Lords.

Mr. Gurney, having kept open his factory until this point was forced to close it and sell off his materials and tools at a loss. The contractors withdrew from the business.

The effect of the Acts passed by Parliament have been to make an otherwise profitable business no longer viable. Mr Gurney's losses included the costs of keeping his workshop open for six years, loss of contracts, loss of mileage duty on the various routes and the costs of patents. He also lost the advantage of being the first to develop a working steam carriage, as others used the intervening period to develop their own machines, and lost his advantage over the railways. The total loss can be calculated at over £200,000. This left him unable to either build and operate steam carriages, or to protect his patents.

Sections of those Acts imposing prohibitory tolls on steam carriages should be immediately repealed, and such tolls should be replaced by those for which horse carriages are liable. Mr Gurney's patent should be extended at public expense for a period of fourteen years beyond the date of its expiry, or a sum of not less than £5000 should be offered to Mr Gurney in lieu of such extension. Other parties have an interest in Mr. Gurney's patent, and half of the money or benefits should be kept aside for Mr. Gurney exclusively."

[edit] Other work

• A key development of his time at the Surrey Institute was use of the oxy-hydrogen blowpipe, normally credited to Robert Hare in which an intensely hot flame was created by burning a jet of oxygen and hydrogen together; the blowpipe was the underpinning of limelight; Gurney its first exponent.

• According to A History of The Growth of The Steam-Engine by Robert H Thurston, Gurney was a proponent of the ammonia engine. "In 1822… Mr. Goldsworthy Gurney, who subsequently took an active part in their introduction, stated, in his lectures, that "elementary power is capable of being applied to propel carriages along common roads with great political advantage, and the floating knowledge of the day places the object within reach." He made an ammonia engine — probably the first ever made — and worked it so successfully, that he made use of it in driving a little locomotive."

• the steam-jet or blastpipe, which served to increase the draw of air through pipes, and which was applied to improve mine and sewerage ventilation, to increase the efficiency of steam-powered stationary engines and blast furnaces, and road or rail vehicles. After the Rainhill trials of 1829, there was considerable controversy as to the genesis of this invention since it became associated in the mind of the public with George Stephenson — probably through the agency of Samuel Smiles' biography of that man. In her 1875 letter to The Times, his daughter traces the path of the idea: Gurney communicated it to Timothy Hackworth, who employed it in his Royal George locomotive, from which Stephenson allegedly took his inspiration for its inclusion in the Rocket. More recent letters acquired by the National Railway Museum suggest that, in fact, Hackworth may have discovered the idea first and/or independently; and Herbert — clearly not a fan of Gurney — seeks to debunk claims for Gurney's invention by comparing the output of Gurney's carriages with those of Trevithick. Gurney's daughter appears to have engaged in considerable promotion of her father's clain to the invention; she donated £250 to memorialise "his" Steam Jet, at the stone-laying ceremony for Truro Cathedral, somehow managing to rope the children of the then Prince of Wales to present the money. (The Prince of Wales, HRH Prince Albert Edward was timidly asked whether he minded, and replied "Oh, why not? The boys would stand on their heads if she wished."^[2])

• he extended the use of the steam-jet to the cleaning of sewers, bridging his mechanical and medical knowledge in the service of the eradication of cholera in the metropolis; and in dealing with mine fires — notably bringing under control a fire known as the burning waste of Clackmannan, which in 1851 had raged for more than 30 years over an area of 26 acres, at the South Sauchie Colliery near Alloa. Gurney injected some 8M cubic feet of chokedamp (a mixture of nitrogen and carbon dioxide) into the mine by means of his steam-jet to extinguish the combustion; and after three weeks, drove water into the mine as a spray from the steam-jet to bring the temperature down from 250 °F to 98 °F. It is reckoned that the value of property saved by the extinguishing of this fire was £200,000.

• he further improved the problematical lighting of theatres which used limelight, with his invention of the Bude-Light. Using a standard flame producer such as an oil lamp and by adding oxygen directly into the flame he produced a dramatically increased bright white light. A system of prisms and lenses distributed Bude Light to every room of his Castle house. Bude lights were fitted in the House of Commons — where it is said that he replaced 280 candles with three such lamps, which lit the House for sixty years until the arrival of electricity — as well as along Pall Mall and in Trafalgar Square where recently refurbished replicas of the two styles originally used can be seen.

• He extended his work to lighthouse lamps, innovating in the choice of source; the use of lenses, and the introduction of identifying on-off patterns enabling seafarers to identify which lighthouse it was they saw flashing.

• The Gurney Stove, another invention which he patented in 1856, was extensively used to heat a wide variety of buildings. The stove's most interesting feature is the use of external ribs to increase the surface area of the stove available for heat transfer. A number of these stoves are still in use to this day, in the cathedrals of Ely, Durham and Peterborough.

• Arising from his successes with mine ventilation he was commissioned in 1852 to improve the gas lighting, heating, and especially the ventilation systems for the new Houses of Parliament at Westminster. Although he had some success in moving air around the palace buildings, ridding the legislature of the foul smell of the Thames was beyond his skill.

• Gurney worked on many other projects, with interests and patents extending from improved steam engine design, to electric telegraphy and the design of musical instruments.
