ABSTRACT:
A coupling link for field/factory assembly of chain lengths and/or attachments thereto; and/or for repairing broken chains or to couple lengths of chain together whenever desired; said coupling link comprising two half link units each of which comprises an overlay/underlay assembly of two or more relatively nested complemental-configured half-link shaped members all of which are stamped out from sheet/plate stock and formed into generally U-shaped sectional form, the paired components thereof being complementarily shaped and internested together. Thus, where the coupling link is under tension loadings the bowed portions of contiguous members yield into mutually reinforcing shapes. Said half-link shaped members have apertured terminal ear portions interdigitally mounted upon a common interconnecting pin; thereby spreading the operational shear loads on the pin.
