Copper Alloy Forms. KMODDL--Collection of Models Table of Contents. Reuleaux Collection of Kinematic Mechanisms, Cornell University The 220 models in Cornell University’s Reuleaux Collection were built in the late 19th century to demonstrate the elements of machine motion, as theorized by the German engineer Franz Reuleaux. The University acquired the models in 1882 for use in teaching and research. This is KMODDL’s core collection and at present is the most extensively documented and enhanced with multimedia resources. Clark Collection of Mechanical Movements, Museum of Science, Boston The Clark Collection at Boston’s Museum of Science is a set of working models of mechanical movements and combinations of drive mechanisms built by American engineer William M.

Clark in the early 20th century. Cornell University Library and the Museum of Science are collaborating in 2005-2006 to integrate the entire Clark Collection into KMODDL; for now a sampling is available here.
