Waldron, KJ 1975, 'ELIMINATION OF THE BRANCH PROBLEM IN GRAPHICAL BURMESTER MECHANISM SYNTHESIS FOR FOUR FINITELY SEPARATED POSITIONS.', American Society of Mechanical Engineers (Paper), no. 75 -WA/DE-23.
A graphical construction is presented which, when used for Burmester mechanism synthesis for four finitely separated positions, enables the designer to avoid solutions which will not pass all design positions without being disconnected. The construction is applied to the circle point curve and locates all regions of that curve which give acceptable solutions. The procedure is simple, requiring only construction of circles and straight lines. It is also compatible with Modler's technique for ensuring that the linkage passes the design positions in the desired order.

A modification to Modler's solution to the problem of obtaining a crank to drive the synthesized linkage through the design positions in a specified order is suggested. This permits location of such cranks by inspection of the circle-point curve and the image poles alone. © 1975 by ASME.
