US Patent No. 3,117,599 (granted Jan. 14, 1964, filed June 22, 1960) by Lothar Strach of Heidelberg, Germany, describing a mechanism for reverse operation of Jacquard looms. After a weft breakage the loom must be run backwards to remove weft picks, and the correct pattern card must be returned to the reading position for each shed. The invention phases the governing cycle against the lifting cycle and uses a hollow shaft carrying pins and cams that shift axially to engage the card-feeding star wheel. This stores the card sequence for reverse and subsequent forward weaving. The document includes six patent drawings, a description, three claims and a list of cited foreign patents.
