An improved articulate chain (10) including pivotally interconnected sections (12,14,16) of spaced, coacting links (18,20,22) having the chain driving members (54) intermediate the pivot connections (58,60) to reduce the chain loads thereon. The links (18,20,22) are locked together in a common plane

An improved articulate chain (10) including pivotally interconnected sections (12,14,16) of spaced, coacting links (18,20,22) having the chain driving members (54) intermediate the pivot connections (58,60) to reduce the chain loads thereon. The links (18,20,22) are locked together in a common plane (56) by integral externally splined projections (82) extending therefrom into the internally splined drive bushing (96) to resist torque loads and increase the structural integrity of the chain (10). The links (18,20,22) are releasably coupled together to permit expeditious disassembly and reassembly thereof for servicing.
