Abstract
An elongated transmission chain is formed by roller assemblies and pairs of link plates extending in parallel spaced relationship outwardly of the roller assemblies to provide a pivotable connection therebetween. A master link pivotably connects the ends of the elongated chain and includes a pair of link plates overlapping the side plates of the roller assemblies at the ends of the chain. These master link plates have a pair of spaced apertures therein which are coaxially aligned with the apertures in the adjacent rollers of the roller assemblies at the ends of the chain. A pair of threaded fasteners seat in these apertures and extend between the master link plates and through the side plates and rollers. These fasteners are threadably engaged in assembly with the master link plates and are of length not greater than the spacing between the outer surfaces of the master link plates so that they do not extend outwardly thereof.
