US Patent 3,985,159 (12 Oct 1976), assigned to Barber-Colman Company, describes an improved heddle transfer mechanism for a triaxial weaving machine. Elongate heddles in weftwise rows are moved from the end of one row to the adjacent end of another by stationary guides (cam surfaces, arcuate ribs, plates) and oscillating heddle receptacles driven by rack-and-pinion and lever linkages. The scan includes a USPTO web printout of the full text with abstract and claims, the printed patent with seven sheets of mechanical drawings, the specification, and a certificate of correction.
