Definitions

  • An auxiliary sprocket 8 having a diameter similar and anaxis of rotation parallel to that of the sprocket 3, is located above the sprocket 3.
  • the sprocket 8 engages the portion of the .chain extending rearwardly from the port 27 and terminating at the anchoringpin 26. Consequently, the sprocket 8 acts as a guiding member which reverses the direction of motion of the engaged portion of the chain.
