The lengths of the links comply with the conditions: L͞H=N͞E=K͞H=C͞E=D͞F, A͞K=A͞C=A͞L=A͞N=B͞D, H͞G=A͞G and C͞D=E͞F. The mechanism is based on the Perrolatz six-bar inversor consisting of two rhomboid linkages, ALHK and ACEN, with the centre of inversion at point A. Point H describes a circle passing through point A, and point E describes straight line q-q which is perpendicular to line AG. Link 5 is a component of a translator consisting of two parallel-crank linkages ACDB and CEFD. When link 1 turns about fixed axis G, link 5 has rectilinear t ranslational motion and its axis EF slides along straight line q-q which belongs to the fixed plane and is parallel to line AB. Links 7 and 11 turn about fixed axis A and link 3 about fixed axis B.
