Abstract
A motion transmitting drive chain (drive chain) is prevented from buckling by applying a relatively small compressive bias force to one side of the pins around which the chain links rotate. The bias force is applied on the locking projection side of the pins axes of rotation such that the links are urged to rotate in the direction required to lock them against each other.
