John Kay (17 June 1704 – c. 1779) was the inventor of the flying shuttle, which was a key contribution to the Industrial Revolution. He is often confused with his namesake:[11][12] fellow Lancastrian textile machinery inventor, the unrelated John Kay who built the first "spinning frame".[13]

Early life[edit]

John Kay was born on 17 June 1704 (in the Julian calendar) in the Lancashire hamlet of Walmersley,[4] just north of Bury. His yeoman farmer father, Robert, owned the "Park" estate in Walmersley, and John was born there.[14] Robert died before John was born, leaving Park to his eldest son. As Robert's fifth son,(out of ten) John was bequeathed forty pounds (at age 21) and an education until the age of 14.[15] His mother was responsible for educating him until she remarried.

Apprenticeship[edit]

He apprenticed with a hand-loom reed maker,but is said to have returned home within a month claiming to have mastered the business.[16] He designed a metal substitute for the natural reed that proved popular enough for him to sell throughout England.[12] After traveling the country, making and fitting wire reeds, he returned to Bury and, on 29 June 1725, both he and his brother, William, married Bury women. John's wife was Anne Holte.[17] His daughter Lettice was born in 1726, and his son Robert in 1728.[18]

In Bury he continued to design improvements to textile machinery; in 1730 he patented a cording and twisting machine for worsted.[19]

The flying shuttle[edit]

In 1733,[20] he received a patent for his most revolutionary device: a "wheeled shuttle" for the hand loom.[21][22] It greatly accelerated weaving,[23] by allowing the shuttle carrying the weft to be passed through the warp threads faster and over a greater width of cloth.[24] It was designed for the broad loom, for which it saved labour over the traditional process, needing only one operator per loom (before Kay's improvements a second worker was needed to catch the shuttle). [25]

Kay always called this invention a "wheeled shuttle", but others used the name "fly-shuttle" (and later, "flying shuttle") because of its continuous speed, especially when a young worker was using it in a narrow loom:

a speed which cannot be imagined, so great that the shuttle can only be seen like a tiny cloud which disappears the same instant.

Opposition[edit]

B: wooden ribs
C: tarred cord

In July 1733, Kay formed a partnership in Colchester to begin fly-shuttle manufacturing.[27] No industrial unrest was anticipated, this being the first device of the modern era to significantly enhance productivity.[28] But by September 1733 the Colchester weavers, were so concerned for their livelihoods that they petitioned the King to stop Kay's inventions.[27]

The flying shuttle was to create a particular imbalance by doubling weaving productivity without changing the rate at which thread could be spun,[29] disrupting spinners, and weavers alike.

Kay tried to promote the fly-shuttle in Bury, but couldn't convince the woollen manufacturers that it was sufficiently robust; he spent the next two years improving the technnology, until it had several advantages over the device specified in the 1733 patent. (Which was to be one of his difficulties in the coming patent disputes.)[30]

In 1738 Kay went to Leeds, where his problem had become royalty collection.[31] (The annual license fee was 15 Shillings per shuttle.)[5] He continued to invent, patenting some machines in the same year, though these were not taken up industrially.[32]

The Shuttle Club[edit]

Kay (and, initially, his partners) launched numerous patent infringement lawsuits, but if any of these cases were successful,[33] compensation was below the cost of prosecution. Rather than capitulate, the manufacturers formed "the Shuttle Club", a syndicate which paid the costs of any member brought to court; their strategy of patent piracy and mutual indeminification nearly bankrupted Kay.[34]

In 1745, he and Joseph Stell patented a machine for cloth ribbon weaving, which they anticipated might be worked by water wheel,[20] but they were unable to advance their plans because of Kay's legal costs.[32] Impoverished and harassed, Kay was compelled to leave Leeds, and he returned to Bury.[35] Also in 1745, John's twelfth (and final) child, William, was born.[10]

Kay remained inventive; in 1746 he was working on an efficient method of salt production,[36] and designing improvements to spinning technology - but that made him unpopular among Bury spinners[35] Also, fly-shuttle use was becoming widespread in weaving,[37] increasing cotton yarn demand and its price - and Kay was blamed.[38]

Life in France[edit]

He had suffered violent treatment in England, but he did not leave the country on that account, but because of his inability to enforce (or profit from) his patent rights.[39] Trudaine's Bureau de Commerce was known to support textile innovations (and would later actively recruit immigrant inventors).[40] Probably encouraged by the prospect of state support,[41] in 1747, Kay left England for France (where he had never been before, and did not speak the language).

State subsidy[edit]

He went to Paris, and throughout 1747 negotiated with the French Government (in English) to sell them his technology.[42]

Denied the huge lump sum he wanted, Kay finally agreed to 3,000 livres plus a pension of 2,500 livre,[5] (annually from 1749) in exchange for his patent, and instruction in its use (to the manufactures of Normandy). He retained the sole rights to shuttle production in France,[43] and brought three of his sons to Paris to make them. Although wary of entering the manufacturing provinces (because of his experiences with rioting weavers in England) he was prevailed upon to do so.

At one time, the French authorities may have discouraged his communication with England,[44] but Kay wrote about the unanticipated use of his technology in England to the French government:

My new shuttles are also used in England to make all sorts of narrow woollen goods, although their use could have been more perfect had the weavers consulted me

—John Kay, Letter in the French Archives nationales[45]

The beginning of mechanization in French textile production is traditionally dated to 1753, with the widespread adoption of the flying shuttle there.[46] Most of these new shuttles were copies, not made by the Kays. John Kay unsuccessfully tried to enforce his manufacturing monopoly, and began to quarrel with the French authorities, briefly returning to England, in 1756.[47] (It is said that he was in his Bury home in 1753 when it was vandalized by a mob - and that he narrowly escaped with his life,[32] [48] but this is probably a 19th-century tale based on earlier Colchester riots. Kay was probably in France throughout the early 1750s.)[49]

William Venn Gough's 1908 Memorial to John Kay (sculpture by John Cassidy) in Bury town centre.[50] Planning began after a 1903 Bury public meeting launched a public subscription. 19th century efforts to acknowledge Kay achieved little, but by 1903 it was felt that Bury "owed John Kay's memory an atonement", and that all Bury should contribute in restitution to "that wonderfully ingenious and martyred man".[51]

He found his prospects in England unimproved; by 1758 he was back in France, which became his adopted country,[5] though he was to visit England at least twice more. In the winter of 1765/66 he appealed to the Royal Society of Arts to reward him for his inventions, and exhibited his card-making machine for them. The Society could find no-one who understood the shuttle,[35] and there was a breakdown in correspondence, so that no award was ever made. He was in England again in 1773, but returned to France in 1774 having lost his pension (at aged 70).

Old age[edit]

His offer to teach pupils if the pension were restored was not taken up, and he spent his remaining years developing and building machines for cotton manufactures in Sens and Troyes. Though he was busy with engineering and letter-writing until 1779, he received only 1,700 livres from the French state over these five years, reaching a state of penury in March 1778 before receiving his final advance (to develop yet more machinery).[52]

His last known letter (1779-06-08) listed his latest achievements for the Intendant de Commerce, and proposed further inventions. But since these were never made, and no more is heard of the 75-year-old Kay, it is believed that he must have died later in 1779.[7]

Legacy[edit]

John Kay's son, Robert, stayed in England,[53] and in 1760 developed the "drop-box",[20][54] which enabled looms to use multiple flying shuttles simultaneously, allowing multicolor wefts.[24]

His son John ("French Kay") had long resided with his father in France. In 1782 he provided an account of his father's troubles to Richard Arkwright, who sought to highlight problems with patent defense in a parliamentary petition.[55]

Ford Madox Brown portrayed Kay and his invention in a mural painting in Manchester Town Hall.

In Bury, Kay has become a local hero: there are still several pubs named after him, as are the Kay Gardens.[56]

Thomas Sutcliffe[edit]

In the 1840s, Thomas Sutcliffe (one of Kay's great-grandsons) campaigned to promote a Colchester heritage for Kay's family. In 1846 he unsuccessfully sought a parliamentary grant for Kay's descendants (in compensation for his ancestor's treatment in England).[32] He was inaccurate in the details of his grandfather's genealogy and story, and his "Fanciful and Erroneous Statements" were discredited by John Lord's detailed examination of primary sources.[57][58][59]

  6. ^ J. B. Thompson's 1964 summary in The achievements of Western civilisation says "date of death unknown". Nobody has yet found exact records or year of his death, though all sources agree it occurred in France between 1764 and 1780. His final year is often given as 1764 (for instance, by the London Science Museum) and often as 1780 (e.g. the BBC's History of the world gives a 1780 death date in the south of France at age 76). Lord (1903) was skeptical that Kay reached 70. And, in the Bury Times (1902-12-27) Lord wrote "The death of John Kay, in Paris, occurred in 1767 or 1768" (see: Bygone Bury p. 108). Lord acknowledges that no Paris death registration exists for John Kay between 1750 and 1770, but says that this is because "documents of all kinds were destroyed during the Commune revolutionary days" —see Lord (1903) p. 169. Mann (1931) reports a July 1779 letter from Kay (largely ruling out earlier dates) but says that he very probably died shortly after the letter was written and that the author of Thoughts on the Use of Machines (1780, probably Dorning Rasbotham) makes a "natural error" in writing that Kay was still alive in 1780.

  37. ^ Mantoux (1928) says that the shuttle appears in some districts much later, and violence against the 'engine weavers' was continuing in 1760s London (pg.208). In Britain, the invention was only acknowledged to be in 'general use' by 1760, and then only for cotton, but it was standard practice much earlier. In 1747, before making any offers to Kay, the French Government inquired in London about the shuttles' uptake, and were assured that "no one uses anything but his shuttles" - Mann (1931) p.467. The impression that the "fly-shuttle" had been very widely adopted by 1746 may have been due to a confusion of this advance with another that Kay had made in 1734-1735: in the method of shuttle bobbin winding to reduce breaks. It was this simpler step that was first widely copied and became known as "Kay's shuttle"; this improved, non-wheeled shuttle was in (dubiously legal) general use throughout Lancashire and Yorkshire by 1737, and also substantially increased productivity - see: Mann (1931) p.467-468.

  59. ^ Whilst Colchester had a long association with weaving and the wool trade, this link seems to rely on an 1848 source (White's History Gazetteer and Directory of the County of Essex) which has been repeated uncritically by later writers. There is an exploration of this in an article by Don Scott in the Essex Journal (Essex Journal: 6–9. Spring 2008. ) which finds no independent evidence of the Colchester connection. (This article also explores the archives of the Royal Society of Arts and their dealings with John Kay.)
