US Patent No. 840,257, granted Jan. 1, 1907 to Hovcep Sarafian of Yonkers, New York, for a pile-fabric loom. The loom weaves a fabric with a pile warp looped around a lower ground warp and raised between two ground warps to form face loops over pile wires. Shogging combs shift the ground warps sideways, heddles move them up and down, and a vertically moving needle carries the pile warp. The document has five sheets of drawings (Figs. 1-17), a specification describing the operating cycle step by step, and 27 claims.
