US Patent No. 1,776,759, granted 23 September 1930 to Rudolf Hrdina of Cerveny Kostelec, Czechoslovakia, for a loom for weaving terry fabrics. It describes a beat-up rod fitted with an adjustable pivoted latch that changes the rod's effective length, so the batten makes either an incomplete or a complete stroke to form terry loops. The latch is controlled by a card or jacquard machine. The text covers the background, the mechanism, how it operates, and two claims, with one drawing sheet of four figures.
