  he patented a lighter shuttle, which could be used for weaving woollen or linen broad-goods. It was introduced into the local woollen industry, which enabled Kay to set up in business as a shuttle maker. He incurred heavy legal costs in taking legal action to defend his patent but failed to recoup anything from those who used his invention.
