Research notes

Checked against the USPTO document: H. Scholz, "Device for Providing Rugs and the Like with Tufts", No. 4,029,031, patented June 14, 1977; filed Mar. 10, 1976; German priority Mar. 14, 1975 (2511266). What it is: a MANUAL tufting tool with two arms side by side, worked alternately against the backing. One arm carries a fixed needle (with a curved point) that guides the yarn; the other carries a blade that slides along the needle and cuts the yarn after each loop, opened by a guide and closed by a spring. The drawing shows a two-handled tool fed from a yarn cone. Why it matters: it is the same two-part, alternate-stroke principle as Ebenezer Ross's 1891 "Turfing Implement" and the Susan Burr, now with a cutting blade, from the co-founder of the firm that became Hofmann Handtuft-Technik. It cites Roberts (US 739,447, 1903), Doubler (US 1,976,709, 1934), Miller et al. (US 2,226,632, 1940), Hurley (US 2,605,727, 1952; already in this database), German 2,402,811 (1975) and British 473,702 (1937).
