What did John Kay invent?

In 1733, John Kay invented the flying shuttle, a device that allowed weavers to weave faster. The original shuttle required two weavers to throw it, but since the flying shuttle was operated by a lever, it required just one weaver.

Kay called his invention a wheeled shuttle, but users frequently called it a flying shuttle because of its speed. John Kay is frequently confused with another John Kay, a clockmaker, who lived in the same time period. Kay's home was attacked in 1753 by textile workers afraid his inventions might take away some of their work. John Kay died around 1780.
