Driver 1 rotates about fixed axis A and is connected by turning pair B to friction wheel 2 which rolls without slipping inside the rim of fixed friction wheel 4. The dimensions of the links comply with the condition: R=2r, where R and r are the radii of the large and small wheels. Pin C of wheel 2, whose axis lies on a circle of radius r, slides along straight guide a, whose axis passes through point A. Wheel 2 is connected by turning pairs E and D to links 5 and 3 which reciprocate in fixed guides F and K. whose axes pass through point A. Points E and D also lie on a circle of radius r. When driver 1 rotates, links 3 and 5 reciprocate.
