US Patent 2,813,547, granted 19 November 1957 to Jean Rabeux and Raymond Jacob of France, for a circular loom. It covers a way of supporting and guiding the shuttles of circular looms with a horizontal shed, using driven and idler wheels, belts and a toothed crown in place of rails that hold the shuttle against the warp threads. The inventors say this reduces strain and breakage of the warp, allows fine, fragile threads and tightly woven cloth, and lets the shuttle be removed easily. The document has three sheets of drawings (Figs. 1-12), a specification and 24 claims.
