The last-named are bi-lateral and form a framework with shafts e<1>, e<3>. The bell cranks F are connected with the frame of the machine by pivoted rods f<1>. When the knife A has descended a pre-determined portion of its stroke the cam operates the levers and the guard bars f move aside the arms of the operator if he has not already withdrawn them. The guard is returned to inoperative position by the spring e2.
