Patent held by Margareth E. Knight
Margaret E. Knight (1838–1914), prolific American inventor of machines and mechanisms for a variety of industrial and everyday purposes. Knight demonstrated a knack for tools and invention from an early age, and she was said to have contrived a safety device for controlling shuttles in powered textile looms when she was 12 years old. In 1868, at which time she was living in Springfield, Massachusetts, she invented an attachment for paper-bag-folding machines that allowed the production of square-bottomed bags. After working to improve her invention in Boston, she patented it in 1870. She later received patents for a dress and skirt shield (1883), a clasp for robes (1884), and a spit (1885). Later still she received six patents over a span of years for machines used in the manufacturing of shoes.
