The lengths of the links comply with the conditions: B͞C=4A͞B, D͞C=2.24A͞B, A͞D=3.25A͞B, B͞E=3.34A͞B, E͞C=5.7A͞B, E͞H=3.34A͞B, E͞F=1.63A͞B, G͞F=K͞H=2.67A͞B, A͞K=4.13A͞B, A͞G=5A͞B, G͞K=2.5A͞B and K͞D=1.44A͞B. Eccentric 1, having its centre at point B turns about fixed axis A. Connecting rod 2 has collar a which encircles eccentric 1 and is connected by turning pair C to link 3 which turns about fixed axis D. Collar a has lug b which is connected by turning pairs E to links 4 and 5. Point E of connecting rod 2 describes a path of which portions x-x and y-y approximate circular arcs of radii H͞E and F͞E and are shown by heavy continuous lines. When point E is on these portions, links 7 and 6 have dwells. The dwells of links 7 and 6 follow immediately one after the other.
