The lengths of the links comply with the conditions: H͞C=C͞E=E͞K=K͞H=D͞F, A͞C=A͞K=B͞D, E͞F =C͞D=A͞B and G͞H=G͞A. The mechanism is based on the Peaucellier-Lipkin six-bar inversor consisting of rhombus linkage HCEK and rhomboid linkage ACHK 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 6 is a component of a translator consisting of two parallel-crank linkages, ACDB and CEFD. When link 1 turns about fixed axis G, link 6 has rectilinear translational motion and its axis EF slides along straight line q-q which belongs to the fixed plane and is parallel to line AB. Links 10 and 11 turn about fixed axis A and link 3 about fixed axis B.
