Each model was mounted on a 15 ¼” square panel. “Mechanical Wonderland,” as the collection was known, consisted of ten arrays of 16 panels each (four by four. With the push of a button, visitors could set the models in motion. Of those original 160 models, the 120 that remain now reside in the Boston Museum of Science. The digitized images you see here are from KMODDL (Kinematic Models for Design Digital Library), a resource of Cornell University Library for the scholarship of kinematics – the geometry of pure motion – and the history and theory of machines.
A catalog published by the museum describes Clark’s motivation for creating his “dictionary of mechanical movements.”
From his early youth Mr. Clark has been interested in machines and has always had a great desire to visualize the science of mechanics. His work of twenty years or more in perfecting the exhibit was inspired by a wish to give inventors and to all who deal in machine technique a short cut to their various ends.
