Arms 1 and 6 turn about fixed axis A and have identical rim segments a and b. Two identical pulleys 3 and 4 rotate about fixed axes B and C. Flexible link 2, shown by a continuous line, is attached with one end at point D to segment a, runs over pulley 4 and is attached with its other end at point E to segment b. Flexible link 5, shown by a dash line, is attached with one end at point F to segment a, runs over pulley 3 and is attached with its other end at point K to segment b. When link 1 oscillates, pulleys 3 and 4 oscillate in opposite directions about axes B and C.
