Description:
This straight-line model has seven links and eight revolute joints counting the grounded link and without counting the connecting crank and coupler link. Without the sliding joint on the right, this linkage would have two degrees of freedom according to the mobility criterion of linkages. The slide constraint on the right removes one degree of freedom. The resulting mechanism produces the straight-line motion of the cylindrical rod on the left which, perhaps, inspired the stork’s bill name by Reuleaux. This straight-line linkage is one of thirty-nine such mechanisms in the Reuleaux-Voigt series, all inspired by James Watt’s original linkage that was used in his famous steam engines at the end of the 18th century. [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.
