Robert Kay (inventor)

• 1. Introduction

  ›

  Robert Kay was born in 1728. Everything that made him worth remembering happened inside a machine most people rarely look at closely, the weaving loom. His contribution eventually earned a name of its own, the drop box, a piece of equipment still tied permanently to his name. What that box actually did, and why it changed how quickly cloth could be produced, is not obvious from the name alone.

  Nor is the story of the family that raised him, a family already deep in the weaving trade before Robert ever touched a loom himself. Their earlier attempt at solving a different problem in the same industry had ended in upheaval. Whether that upheaval shaped how Robert approached his own, quieter improvement is one of the questions this documentary sets out to answer.

• 2. His Father's Shuttle

  ›

  John Kay and Ann Holt were Robert's parents, raising their son in Bury, Lancashire, where he grew up to work as a shuttlemaker. He married in 1748 and went on to have several children, settling into the same trade his father had already reshaped.

  Around 1733, Robert's father John Kay had invented the flying shuttle, also known as the wheel-shuttle, years before Robert took up shuttlemaking in earnest. The device reshaped weaving. John's gift for engineering outpaced his gift for business, and money troubles may have pushed him to leave England.

  In 1747, John Kay emigrated to France, and Robert followed along with two of his brothers, James and John. Robert eventually made his way back to Bury, most likely in 1759. He came home ready to turn what he had learned into a problem of his own to solve.

• 3. The Drop Box

  ›

  In either 1759 or 1760, Robert devised a way to deploy multiple shuttles at once, ready for a weaver to switch between them. That arrangement let a weaver work with wefts of more than one colour, so cross-striped cloth became far easier to produce.

  Kay housed these extra shuttles at the side of the loom, in a compartment that weavers soon started calling the drop box. He never patented the drop box, choosing instead to move on to other problems inside the loom.

• 4. Checks Ticking And Cards

  ›

  Checked cloth and bed ticking were next on Kay's list, both needing further tweaks to a shuttle mechanism he had already reworked once. He also devised a mechanism for manufacturing the cards used inside carding machines, stretching his fixes beyond the loom into the wider cloth-making process.

  The drop box most likely pushed more weavers toward using the flying shuttle in the first place, since the two devices worked best paired together. Pairing them made the loom's mechanism more complicated to run, but it let weavers turn out even fairly complex cloths at a much faster pace.

  Patterned cloth that once meant slower work could now keep pace with a weaver's usual output, letting more intricate designs reach customers without extra delay.
