Flying Shuttle

The Bottleneck the Flying Shuttle Removed

Weaving is a crossing of two sets of threads: the warp, held lengthwise on the loom, and the weft, carried across it. When weaving on a loom, the shuttle carries the yarn that forms the weft through the fibers of the warp, one crossing at a time, and the speed of weaving is the speed at which that shuttle can be passed and the weft beaten into place. On a handloom worked by throwing the shuttle from hand to hand, the width of cloth that could be woven was restricted by the reach of the weaver, and required the use of both hands, and two weavers were needed to operate larger looms, passing the shuttle between them across a broad warp. Cloth width and weaving speed were therefore limited by human arms, and weaving was the slow stage of textile production, the stage every spinner's yarn waited on.

John Kay's flying shuttle, developed in 1733, mechanized the throw. The shuttle sat in a box at the side of the loom and was driven across, through the shed of raised and lowered warp threads, by a sharp pull on a cord, flying on a track the length of the loom's width. The flying shuttle enabled the weaver to propel the shuttle through a wider strip of cloth with a single hand, and allowed the other hand to perform the combing, the beating-up that compacts the newly laid weft into the cloth. One weaver could now weave broad cloth alone, and could weave any cloth faster, because the throw no longer cost a reach, a catch and a change of hands on every single pass. This speeded the process and thus increased production, at the exact point where the whole industry's output had been capped.

Faster Weaving, Hungrier for Yarn, and Kay's Fate

With increased speed and production, the demand for yarn rose, and thus this early invention spurred the textile industry in Great Britain. The flying shuttle did not merely make the same industry quicker; it unbalanced it, productively. Weavers who could suddenly consume yarn far faster than before pulled demand through the spinning stage, and initially production outstripped supply, and weavers were put into competition for the limited supply of yarn. That pressure, spinners unable to feed the faster looms, is the direct background to the spinning inventions that followed, the spinning jenny, the water frame and the mule, each multiplying what one spinner could produce. The sequence, a weaving improvement creating a spinning crisis, and spinning improvements later creating pressure to mechanize weaving itself with the power loom, is the engine-room story of the Industrial Revolution in textiles, and the flying shuttle is its first turn.

The inventor's own story was the opposite of the industry's. The technology was seen as a threat because of the changes it forced, and Kay's innovation led to machine wreckers attacking his property, weavers who feared, not unreasonably, that faster looms meant fewer livelihoods. Kay also suffered because his invention was used by others without his getting any royalties: the trials that he faced, legal and financial, led him to leave for France, and he died without getting any lasting benefit from his invention. The flying shuttle therefore stands in the textile vocabulary with a double significance. Technically, it is the device that freed the shuttle from the weaver's reach, made wide cloth a one-person job, and freed a hand for the combing that finishes each row. Historically, it is the development that set the tempo of the Industrial Revolution in cloth, and its inventor's ruin is a standing reminder that the people who start such changes are rarely the people they enrich.
