US Patent No. 1,694,254, granted 4 December 1928 to Otto A. Frederickson of Wethersfield, Connecticut, and assigned to the Wire-Mold Company. It describes a circular loom in which a tilting nose on the shuttle replaces heddles for opening the shed, directing warp threads over or under the shuttle. Fixed pins on the drum wall tilt the nose, and the pins can be repositioned to change the order of thread shifting. The patent has two sheets of drawings (side section, perspective detail, and diagrammatic view of the drum), a specification, and ten claims.
