US Patent 3,732,895 (granted 15 May 1973) to Walter Keim, assigned to Firma Grosse Webereimaschinen GmbH, describes a reversing mechanism for a double-stroke open-shed jacquard loom. When the loom is reversed after a weft break, the blades that actuate the heddle-control rods first back up only to the open-shed or closed-shed position and then orbit forward again, so the rods and drop needles are not damaged. The mechanism uses an input shaft, a rotating element carrying spring-centered sliding pins, and two counter-rotating notched disks, and the card reader is reversed along with the drive. The document has the abstract, background, description, 10 claims and four sheets of mechanical drawings.
