differential screw mechanism

This model is an example of a screw kinematic chain. There are two screws of different pitch. Motion of the crank produces a differential motion of the slider. Such mechanisms were used in precision machining and measurement in the late 19th century. A similar mechanism can be found in the Reuleaux-Voigt catalog, Models M07, M08. The University of Karlsruhe models were created by Professor Ferdinand Redtenbacher (1809-1863). Among his students were Karl Benz and Franz Reuleaux. It is now clear that many of the Reuleaux models in Berlin were based on the designs of his former professor in Karlsruhe.
