- This model is a beautiful pedagogical device for demonstrating the tendency of a moving belt to move to a larger diameter on the conical cylinder as the circular cylinder in rotated. The use of belt and pulley mechanisms was almost universal in the age of steam engine manufacturing to distribute power throughout the work stations. To prevent the belts from slipping off their pulleys and to avoid the use of pulley wheels with end face plates, the pulley wheels were spherically crowned. Any tendency of the belt to slip off would be self- corrected by the drift of the belt toward the larger diameter of the center of the wheel. This phenomenon was known at the time of Cambridge professor Robert Willis (1841). It also demonstrates the connection between mechanics and geometry because of the role that friction plays in the dynamics between the belt and the wheel surface. [Francis Moon, 2003-07-01]
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. The Reuleaux models are classified according to the alphanumeric schema employed in the catalog of the manufacturer, Gustav Voigt. The letter in a model's ID (e.g., B14 or S35) refers to a class of mechanism; the number is a specific instance of the class. This classification scheme is a simplified version of the taxonomy of machine elements elaborated in Reuleaux's work. - Repository:
