Patent ID: 7310934

Claim:
A method of making one-way chain for use as a part of an aircraft tie-down having a screw-type binder mechanism including a link receiving receptacle for a one-way link, the method comprising the steps of: providing an unmodified chain having a plurality of welded links; feeding the unmodified chain into an automated shaping machine constructed and arranged to shape welded links in separate shaping events; and shaping welded links to form shaped links in a series of separate shaping events that shape the respective welded links so that a first width of a greatest planar dimension of a forward end of the respective shaped link is narrower than a second width of the greatest planar dimension of a rearward end of the respective shaped link, such that the forward end is sized to fit into the link receiving receptacle of the screw-type binder mechanism and the rearward end will not fit into the link receiving receptacle.
