US Patent No. 120,474, granted October 31, 1871 to Henry Williamson of Williamsburg, New York, for an improved lace-knitting (crocheting) machine. The needles work independently of each other and are driven by Jacquard pattern cards or cylinders, while all the thread-guides are mounted on a single guide bar. This replaces the many guide bars of earlier machines and allows wide, non-repeating patterns. The document has two sheets of mechanical drawings and a two-page specification with a single claim.
