The lengths of the links comply with the conditions: C͞B=2.68A͞C, O͞B=1.91A͞C, D͞G=A͞C, E͞D=2.32A͞C, A͞O=2.82A͞C, O͞E=2.38A͞C, A͞E=3.64A͞C, B͞G=1.86A͞C and C͞G=4.2A͞C. Sliding member 3 slides along guide a-a of radius O͞B, turning through angle α about axis 0. When point C of crank 1 travels along the portion of the circle indicated by a heavy continuous line, point G of connecting rod 4 describes a path of which a portion approximates a circular arc of radius D͞G (indicated by a heavy continuous line) with its centre at point D. When crank 1 rotates about fixed point A, link 2 oscillates about fixed axis E and has a dwell when point G is on the portion of its path indicated by a heavy continuous line.
