Patent specification, dated March 16, 1793, from John Daniel Belfour of Elsinore, Denmark, for a machine that makes ropes and cordage. Each rope yarn is wound on its own spring-controlled reel mounted on spindles in a large frame, so every yarn stays tight and bears an equal share of the strain when the strand is twisted. The text describes the great frame, reels, grate-work, driving wheel, a separating machine, the "top minor" (a conical guide), and nippers, with dimensions for a 22-inch cable. Three engraved plates (IX-XI) show the machines.
