  • Device for tensioning a chain
    Patent number: 4040305
    Abstract: A tensioning device for a run of a chain comprises a toothed roller, for engagement with the chain, rotatably mounted on a crank-pin which is rotated about an axis by resilient means to bring the roller into tensioning contact with the chain. Angular movement of the crank-pin is limited by means carried by the output member of a freewheel. This output member is urged by further resilient means which are weaker than the first mentioned resilient means in the direction to tension the chain.
