The lengths of the links comply with the conditions: O͞B=2O͞A, C͞B=1.25O͞A, A͞C=2O͞A, D͞E=6.5O͞A, G͞E=2.8O͞A, O͞D=2.62O͞A, A͞G=3.15O͞A and B͞D=2.5O͞A . Eccentric 1, with its centre at point 0, turns about fixed axis A. Connecting rod 2 has collar b which encircles eccentric 1. Collar b has two lugs d and c which are connected by turning pairs D and B to links 4 and 3. Point D of connecting rod 2 describes a path of which portions x-x and y-y, shown by heavy continuous lines, approximate a circular arc of radius E͞D with the centre at point E. When point D is on these portions, link 5 has dwells.
