US Patent No. 1,426,641, granted 22 August 1922 to James Hirst of Melrose, Massachusetts, for a circular loom that weaves seamless tubular fabric. The loom uses gear-driven shuttles that travel in a circle around a mandrel, with heddles driven directly by rotating inner and outer cylindrical cams. The specification covers removable heddle frames, warp tension fingers, an adjustable weft packer and spreader on the shuttle, and a modified form with separate heddle bars. It has six sheets of mechanical drawings, the written specification, and ten claims.
