US Patent 3,076,482, granted 5 February 1963 to Christian Christiansen and Einar Håøya of Norway, assigned to Mandals Reberbane Christiansen & Co. It describes an improved shuttle arrangement for circular looms that weave hoses and other tubular textiles. Rollers on the shuttle carrier have notched flanges that take up the radial (centrifugal and centripetal) forces on a fast-moving shuttle and keep the warp threads evenly spaced as the shed opens and closes. The patent has two sheets of drawings (Figs. 1-4), a specification, and two claims.
