The lengths of the links comply with the condition: C͞B:C͞A=B͞Q:A͞P. Points C, P and Q lie on a single straight line. Direction EQ of link 2 should be parallel to direction DP. Link 1 turns about fixed axis D and is connected by turning pairs C and E to links 3. 4 and 2. Link 3 is connected by turning pairs A and B to links 6 and 7 which are connected, in turn, by turning pairs P and Q to sliders 5 and 8. Sliders 5 and 8 move along axis Ca of link 4. Link 2 is connected by turning pair Q to slider 8. When link 1 turns about axis D, link 6 has translational motion and all of its points describe circles of radius D͞E.
