After Menzies conceived his idea of breaking off coal with machines in 1761, many inventors subsequently followed his proposals through into the practice of underground working. More than one century later, Garforth became one of the principal pioneers of machine-holing combined with the longwall method of working in order to reduce production costs and increase the yield of coal. Having been appointed agent to Pope \& Pearson's Collieries, West Yorkshire, in 1879, of which company he later became Managing Director and Chairman, he gathered a great deal of experience with different methods of cutting coal. The first disc machine was exhibited in London as early as 1851, and ten years later a pick machine was invented. In 1893 he introduced an improved type of deep undercutting machine, his "diamond" disc coal-cutter, driven by compressed air, which also became popular on the European continent.

Besides the considerable economic advantages it created, the use of machinery for mining coal increased the safety of working in hard and thin seams. The improvement of safety in mining technology was always his primary concern, and as a result of his inventions and his many publications he became the leading figure in the British coal mining industry at the beginning of the twentieth century; safety lamps still carry his name. In 1885 he invented a firedamp detector, and following a severe explosion in 1886 he concentrated on coal-dust experiments. From the information he obtained of the effect of stone-dust on a coal-dust explosion he proposed the stone-dust remedy to prevent explosions of coal-dust. As a result of discussions which lasted for decades and after he had been entrusted with the job of conducting the British coal-dust experiments, in 1921 an Act made it compulsory in all mines which were not naturally wet throughout to treat all roads with incombustible dust so as to ensure that the dust always consisted of a mixture containing not more than 50 per cent combustible matter. In 1901 Garforth erected a surface gallery which represented the damaged roadways of a mine and could be filled with noxious fumes to test self-contained breathing apparata. This gallery formed the model from which all the rescue-stations existing nowadays have been developed.

Porter graduated from Hamilton College, New York, in 1845, read law in his father's office, and in the autumn of 1847 was admitted to the Bar. He practised for six or seven years in Rochester, New York, and then in New York City. He was drawn into engineering when aged about 30, first through a client who claimed to have invented a revolutionary type of engine and offered Porter the rights to it as payment of a debt. Having lent more money, Porter saw neither the man nor the engine again. Porter followed this with a similar experience over a patent for a stone dressing machine, except this time the machine was built. It proved to be a failure, but Porter set about redesigning it and found that it was vastly improved when it ran faster. His improved machine went into production. It was while trying to get the steam engine that drove the stone dressing machine to run more smoothly that he made a discovery that formed the basis for his subsequent work.

Porter took the ordinary Watt centrifugal governor and increased the speed by a factor of about ten; although he had to reduce the size of the weights, he gained a motion that was powerful. To make the device sufficiently responsive at the right speed, he balanced the centrifugal forces by a counterweight. This prevented the weights flying outwards until the optimum speed was reached, so that the steam valves remained fully open until that point and then the weights reacted more quickly to variations in speed. He took out a patent in 1858, and its importance was quickly recognized. At first he manufactured and sold the governors himself in a specially equipped factory, because this was the only way he felt he could get sufficient accuracy to ensure a perfect action. For marine use, the counterweight was replaced by a spring.

Higher speed had brought the advantage of smoother running and so he thought that the same principles could be applied to the steam engine itself, but it was to take extensive design modifications over several years before his vision was realized. In the winter of 1860–1, J.F. Allen met Porter and sketched out his idea of a new type of steam inlet valve. Porter saw the potential of this for his high-speed engine and Allen took out patents for it in 1862. The valves were driven by a new valve gear designed by Pius Fink. Porter decided to display his engine at the International Exhibition in London in 1862, but it had to be assembled on site because the parts were finished in America only just in time to be shipped to meet the deadline. Running at 150 rpm, the engine caused a sensation, but as it was non-condensing there were few orders. Porter added condensing apparatus and, after the failure of Ormerod Grierson \& Co., entered into an agreement with Joseph Whitworth to build the engines. Four were exhibited at the 1867 Paris Exposition Universelle, but Whitworth and Porter fell out and in 1868 Porter returned to America.

Porter established another factory to build his engine in America, but he ran into all sorts of difficulties, both mechanical and financial. Some engines were built, and serious production was started c. 1874, but again there were further problems and Porter had to leave his firm. High-speed engines based on his designs continued to be made until after 1907 by the Southwark Foundry and Machine Company, Philadelphia, so Porter's ideas were proved viable and led to many other high-speed designs.

He was the son of David Bruce, typefounder, who introduced stereotyping into the USA. As a boy, he was employed on various tasks about the typefoundry and printing works of D. \& G. Bruce until 1819, when he was apprenticed to William Fry of Philadelphia, at that time the most eminent printer in America. However, he ran away from Fry and returned to his father, from whom he continued to learn the typefounder's trade. Around 1828 he moved to Albany, where he took charge of a typefoundry. Two years later he was back in New York and joined the firm of George Bruce \& Co. In 1834 he moved to New Jersey, where he set about producing the improved form of typecasting machine for which he is chiefly known. Having achieved success, he set up in business again in New York and remained there until his retirement some twenty-five years before his death. Bruce in fact invented the first effective typecasting machine in New York in 1838 and patented it the same year. His machine incorporated a force pump to drive the molten metal from the pot into the mould. The machine, operated by a wheel turned by hand, could produce forty sorts of various sizes per minute. The machine speeded up the production of type: between 3,000 and 7,000 pieces of type could be cast by hand, whereas these figures were raised to between 12,000 and 20,000 by the casting machine. The Bruce caster was not introduced into Britain until 1853. It was later supplanted by improved machines, notably that invented by Wicks.

Several members of Champion's Quaker family were actively engaged as merchants in Bristol during the late seventeenth and the eighteenth centuries. Port records show Nehemiah in receipt of Cornish copper ore at Bristol's Crews Hole smelting works by 1706, in association with the newly formed brassworks of the city. He later became a leading partner, managing the company some time after Abraham Darby left the Bristol works to pursue his interest at Coalbrookdale. Champion, probably in company with his father, became the largest customer for Darby's Coalbrookdale products and also acted as Agent, at least briefly, for Thomas Newcomen.

A patent in 1723 related to two separate innovations introduced by the brass company.

The first improved the output of brass by granulating the copper constituent and increasing its surface area. A greater proportion of zinc vapour could permeate the granules compared with the previous practice, resulting in the technique being adopted generally in the cementation process used at the time. The latter part of the same patent introduced a new type of coal-fired furnace which facilitated annealing in bulk so replacing the individual processing of pieces. The principle of batch annealing was generally adopted, although the type of furnace was later improved. A further patent, in 1739, in the name of Nehemiah, concerned overshot water-wheels possibly intended for use in conjunction with the Newcomen atmospheric pumping engine employed for recycling water by his son William.

Champion's two sons, John and William, and their two sons, both named John, were all concerned with production of non-ferrous metals and responsible for patented innovations. Nehemiah, shortly before his death, is believed to have partnered William at the Warmley works to exploit his son's new patent for producing metallic zinc.

Robert Kay improved his father John's flying shuttle by inventing the drop box, in which up to four shuttles could be stored one below the other. The weaver's left hand controlled levers and catches to raise or lower the drop box in order to bring the appropriate shuttle into line with the shuttle race on the slay. The shuttle could then be driven across the loom, leaving its particular type or colour of weft. On the earliest power looms of Edmund Cartwright in 1785, and for many years later, it was possible to use only one shuttle. In 1845 Squire Diggle of Bury, Lancashire, took out a patent for mechanizing the drop box so that different types or colours of weft could be woven without the weaver attending to the shuttles. He used an endless chain on which plates of different heights could be fixed to raise the boxes to the required height; later this would be operated by either the dobby or Jacquard pattern-selecting mechanisms. He took out further patents for improvements to looms. One, in 1854, was for taking up the cloth with a positive motion. Two more, in 1858, improved his drop box mechanism: the first was for actually operating the drop box, while the second was for tappet chains which operated the timing for raising the boxes.

John Kay was the youngest of five sons of a yeoman farmer of Walmersley, near Bury, Lancashire, who died before his birth. John was apprenticed to a reedmaker, and just before he was 21 he married a daughter of John Hall of Bury and carried on his trade in that town until 1733. It is possible that his first patent, taken out in 1730, was connected with this business because it was for an engine that made mohair thread for tailors and twisted and dressed thread; such thread could have been used to bind up the reeds used in looms. He also improved the reeds by making them from metal instead of cane strips so they lasted much longer and could be made to be much finer. His next patent in 1733, was a double one. One part of it was for a batting machine to remove dust from wool by beating it with sticks, but the patent is better known for its description of the flying shuttle. Kay placed boxes to receive the shuttle at either end of the reed or sley. Across the open top of these boxes was a metal rod along which a picking peg could slide and drive the shuttle out across the loom. The pegs at each end were connected by strings to a stick that was held in the right hand of the weaver and which jerked the shuttle out of the box. The shuttle had wheels to make it "fly" across the warp more easily, and ran on a shuttle race to support and guide it. Not only was weaving speeded up, but the weaver could produce broader cloth without any aid from a second person. This invention was later adapted for the power loom. Kay moved to Colchester and entered into partnership with a baymaker named Solomon Smith and a year later was joined by William Carter of Ballingdon, Essex. His shuttle was received with considerable hostility in both Lancashire and Essex, but it was probably more his charge of 15 shillings a year for its use that roused the antagonism. From 1737 he was much involved with lawsuits to try and protect his patent, particularly the part that specified the method of winding the thread onto a fixed bobbin in the shuttle. In 1738 Kay patented a windmill for working pumps and an improved chain pump, but neither of these seems to have been successful. In 1745, with Joseph Stell of Keighley, he patented a narrow fabric loom that could be worked by power; this type may have been employed by Gartside in Manchester soon afterwards. It was probably through failure to protect his patent rights that Kay moved to France, where he arrived penniless in 1747. He went to the Dutch firm of Daniel Scalongne, woollen manufacturers, in Abbeville. The company helped him to apply for a French patent for his shuttle, but Kay wanted the exorbitant sum of £10,000. There was much discussion and eventually Kay set up a workshop in Paris, where he received a pension of 2,500 livres. However, he was to face the same problems as in England with weavers copying his shuttle without permission. In 1754 he produced two machines for making card clothing: one pierced holes in the leather, while the other cut and sharpened the wires. These were later improved by his son, Robert Kay. Kay returned to England briefly, but was back in France in 1758. He was involved with machines to card both cotton and wool and tried again to obtain support from the French Government. He was still involved with developing textile machines in 1779, when he was 75, but he must have died soon afterwards. As an inventor Kay was a genius of the first rank, but he was vain, obstinate and suspicious and was destitute of business qualities.

Benton spent his childhood in Milwaukee and La Crosse, where he early showed a talent for mechanical invention. His father was a lawyer with an interest in newspapers and who acquired the Milwaukee Daily News. Benton became familiar with typesetting equipment in his father's newspaper office. He learned the printer's trade at another newspaper office, at La Crosse, and later worked as bookkeeper at a type foundry in Milwaukee. When that failed in 1873, Benton acquired the plant, and when he was joined by R.V.Waldo the firm became Benton, Waldo \& Co. Benton began learning and improving type-cutting practice. He first devised unit-width or "self-spacing" type which became popular with compositors, saving, it was reckoned, 20 per cent of their time. Meanwhile, Benton worked on a punch-cutting machine to speed up the process of cutting letters in the steel punches from which matrices or moulds were formed to enable type to be cast from molten metal. His first mechanical punch-cutter worked successfully in 1884. The third machine, patented in 1885, was the model that revolutionized the typefounding operation. So far, punch-cutting had been done by hand, a rare and expensive skill that was insufficient to meet the demands of the new typesetting machines, the monotype of Lanston and the linotype of Merganthaler. These were threatened with failure until Benton saved the day with his automatic punch-cutter. Mechanizing punch-cutting and the forming of matrices made possible the typesetting revolution brought about by mono-and linotype.

In 1892 Benton's firm merged with others to form the American Type Founders Company. Benton's equipment was moved to New York and he with it, to become a board member and Chief Technical Advisor. In 1894 he became Manager of the company's new plant for type manufacture in Jersey City. Benton steadily improved both machinery and processes, for which he was granted twenty patents. With his son Morris Fuller, he was also notable and prolific in the field of type design. Benton remained in active association with his company until just two weeks before his death.

Brotan, who was Chief Engineer of the main workshops of the Royal Austrian State Railways at Gmund, found that locomotive inner fireboxes of the usual type were both expensive, because the copper from which they were made had to be imported, and short-lived, because of corrosion resulting from the use of coal with high sulphur content. He designed a firebox of which the side and rear walls comprised rows of vertical watertubes, expanded at their lower ends into a tubular foundation ring and at the top into a longitudinal water/steam drum. This projected forward above the boiler barrel (which was of the usual firetube type, though of small diameter), to which it was connected. Copper plates were eliminated, as were firebox stays.

The first boiler to incorporate a Brotan firebox was built at Gmund under the inventor's supervision and replaced the earlier boiler of a 0−6−0 in 1901. The increased radiantly heated surface was found to produce a boiler with very good steaming qualities, while the working pressure too could be increased, with consequent fuel economies. Further locomotives in Austria and, experimentally, elsewhere were equipped with Brotan boilers.

Disadvantages of the boiler were the necessity of keeping the tubes clear of scale, and a degree of structural weakness. The Swiss engineer E. Deffner improved the latter aspect by eliminating the forward extension of the water/steam drum, replacing it with a large-diameter boiler barrel with the rear section of tapered wagon-top type so that the front of the water/steam drum could be joined directly to the rear tubeplate. The first locomotives to be fitted with this Brotan-Deffner boiler were two 4−6−0s for the Swiss Federal Railways in 1908 and showed very favourable results. However, steam locomotive development ceased in Switzerland a few years later in favour of electrification, but boilers of the Brotan-Deffner type and further developments of it were used in many other European countries, notably Hungary, where more than 1,000 were built. They were also used experimentally in the USA: for instance, Samuel Vauclain, as President of Baldwin Locomotive Works, sent his senior design engineer to study Hungarian experience and then had a high-powered 4−8−0 built with a watertube firebox. On stationary test this produced the very high figure of 4,515 ihp (3,370 kW), but further development work was frustrated by the trade depression commencing in 1929. In France, Gaston du Bousquet had obtained good results from experimental installations of Brotan-Deffner-type boilers, and incorporated one into one of his high-powered 4−6−4s of 1910. Experiments were terminated suddenly by his death, followed by the First World War, but thirty-five years later André Chapelon proposed using a watertube firebox to obtain the high pressure needed for a triple-expansion, high-powered, steam locomotive, development of which was overtaken by electrification.
