A lever is pivotally mounted at its base end to the frame and the leading end of the lever has a roller rotatably mounted thereto. The roller is adapted to move vertically guided by a guide member mounted to the under surface of the sliding member as the lever pivots on its base end. A spring is provided for helping the movements of the transfer bar between the first and second positions.
