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.

The 120 models in the Museum’s collection are displayed in glass cases, each of which houses 16 of the models. KMODDL groups the Clark models by case; they are numbered according to their number designation in the original display cases.
