The lengths of the links comply with the conditions: K͞F=M͞G=L͞G=A͞F, F͞G=•A͞L=K͞M, A͞B=E͞D=E͞F=G͞H, B͞E=D͞H=E͞G=A͞F and B͞E=(1+sqrt(2))A͞B. Figures AFGL and KFGM are parallel-crank linkages; figures ABEF and EDHG are crossed-crank linkages. Link 9 turns about fixed axis K and is connected by turning pairs F to links 2 and 5. Link 2 is connected by turning pairs A to links 1 and 3. Link 4 is connected by turning pairs B, D and E to links 3, 6 and 5. Link 7 turns about fixed axis M and is connected by turning pairs G and H to links 5, 8 and 6. Link 8 is connected by turning pair L to link 1. When link 7 turns about axis M, link 1 has rectilinear translation in the direction coinciding with line KM.
