- This model is a compound mechanism consisting of a belt drive transmission and a planetary-ring gear train. Belt drive mechanisms can be seen in models in the V-series and planetary gear sets in models in the G-series. In this model, the ring gear is inside the inner belt pulley. The crank is directly coupled to the outside pulley as well as to the small ‘sun’ gear on the planetary gear set. The planet gear rotates about a separate fixed shaft that reverses the motion of the ring gear. A belt shaft slide similar to Model V-16 is used to move the belt. As one turns the crank with, say, the belt on the outside pulley, one can first shift the belt to the neutral wheel and then to the inner belt wheel that is also the outside of the ring gear that rotates in a direction opposite to the motion of the crank.

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:
