US Patent 4,365,651 (granted 28 December 1982 to Soichi Torii, Torii Winding Machine Co., Kyoto) describes a shuttle for a circular loom that weaves tubular fabric. The shuttle has a main body, brackets that hold a bobbin, and a pivoting lever with an inside guide wheel. Inclined outside wheels carry the gravity and centrifugal loads while the shuttle runs along annular guides, and an adjustable connecting lever makes mounting and removal easy. The document contains the abstract, claims, description and eight sheets of patent drawings of the loom and shuttle.
