Note 84 — PAPER 27
Reading edition
It is perhaps significant that the first paper of the First Conference on Mechanisms at Purdue University was Allen S. Hall's "Mechanisms and Their Classification," which appeared in Machine Design, December 1953, vol. 25, pp. 174-180. The place of classification in kinematic synthesis is suggested in Ferdinand Freudenstein's "Trends in Kinematics of Mechanisms," Applied Mechanics Reviews, September 1959, vol. 12, pp. 587-590.
