- In this mechanism two parallel axels are couple by two belts, one of which is crossed. One of the axels has three circular rollers, two of which slip relative to the axel rotation. A central shift lever can move either belt from its idler pulley onto the drive pulley thereby providing a means to change direction of rotation between the two axels. Reuleaux’s attribution of this mechanism to Sellers could refer to one of the two American cousins William Sellers (1824-1905) of Philadelphia or Coleman Sellers (1827-19) of Niagara Falls. The latter was president of the ASME (1886-1887) and designed large dynamics for power plants at Niagara Falls. His cousin William did a lot of work with screw threads. Reuleaux wrote letters to both cousins (in English) and sent a copy of his German translation of Hiawatha to William Sellers’ wife in 1894. [See History links in KMODDL] [Francis Moon, 2004-07-00]
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:
