- The classic slider-crank mechanism (model C02) has four links connected by three revolute joints and one prismatic joint of lower pairs or surface contact. In this inversion, the crank link is replaced by a circular guide, and the revolute joint between the crank and coupler link is replaced by a higher pair joint, i.e. a cylinder sliding in the circular slot. Similarly for the slider a surface-joint pair is replaced by a pin in a slot. The replacement of lower pair or surface contact joints by line contact joints results in kinematic linkage with only two links. Reuleaux called this a reduced kinematic chain. One of Reuleaux’s important contributions to kinematics of mechanisms was the recognition that several different-looking mechanisms in fact belonged to the same class of kinematic chain, in the case of this model the class of slider-crank kinematic circuits.

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:
