- This model is a compound mechanism combining a belt drive transmission (see the V- series) with a set of gear wheels. The belt drive couples the rotation of two parallel shafts and is similar to the one in Model Y-3, with two driven pulley wheels and a central neutral wheel. The crank is coupled to both the outside pulley wheel as well as a coaxial gear wheel. This gear transfers rotation to another shaft through a mating gear. The outside set of gears uses a smaller intermediate gear to reverse the motion. The resulting gear rotation is opposite in direction to that of the crank and is coupled through a shaft to the inside belt pulley. As one turns the crank with, say, the belt initially on the outside pulley, one can shift the belt first to the neutral pulley wheel, and then to the inside pulley that turns in a direction opposite to the crank motion.

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:
