	No. 256:Reuleaux's Machines
		Reuleaux eventually went aground on the unhappy fact that it is not the last.
		Reuleaux eventually wrote a second book that addressed such issues; but by then he was 71, and he'd lost his audience.
		Reuleaux's wide-ranging mind was more concerned with beauty than it was with the needs of the marketplace.

		Franz Reuleaux was born in Eschweiler, a suburb of Aachen, in 1829.
		Reuleaux was not a major inventor in the mold of James Watt, nor was he an entrepreneur in the style of the Siemens brothers.
		Franz Reuleaux was one of the optimists of the machine age who believed in the power of technology to free mankind from the slavery and prejudices of peasant life, in spite of the terrible toll on the industrial worker.

	Mechanical and Aerospace Engineering : Reuleaux Collection
		Franz Reuleaux's mission was to codify, analyze, and synthesize kinematic mechanisms so that engineers could approach machine design in a ration-al way.
		Reuleaux was also one of the first to use an abstract symbol representation of machines, inventing the idea of a kinematic pair.
		The Reuleaux models were a cornerstone of this effort; in a letter to White in 1886 asking for financial resources to rebuild the program, Thurston comments that the collection was one of the few strong assets of the college.

	ASEE PRISM - Summer 2004 - Pure Motion
		The Reuleaux models were the brainchild of the 19th-century German engineering professor, Franz Reuleaux (1829-1905), who was known for his theories on kinematicsâ”the science of pure motion.
		Reuleaux designed many of his mechanisms so that they could be taken apart and put back together in different ways to see how their changes affected the mechanism.
		Reuleauxâs study of the scientific principles that underlie machines earned him an international reputation and the moniker âthe father of modern kinematics.â Reuleaux was born in 1829, a time when most people regarded machines with awe.

	Ivars Peterson's MathTrek - Rolling with Reuleaux
		The simplest example is the Reuleaux triangle, named after distinguished mechanical engineer Franz Reuleaux (1829–1905), who was a teacher in Berlin more than 100 years ago.
		One way to draw a Reuleaux triangle is to start with an equilateral triangle, which has three sides of equal length.
		Therefore, an unlimited number of curves of constant width are possible, and the Reuleaux triangle happens to be the family member of least area.

		To form a Reuleaux Triangle, take the three points at the corners of an equilateral triangle and connect each pair of points by a circular arc centered at the remaining point.
		The actual drill bit for the square is a Reuleaux triangle made concave in three spots to allow for unobstructed corner-cutting and the discharge of shavings.
		The Reuleaux triangle may also form the shape of the piston in a rotary, or Wankel, engine, in which gasoline burns in crescent-shaped chambers, turning a rotating piston that drives an axle through its center.

		The simplest such curve is known as the Reuleaux triangle, named after engineer Franz Reuleaux, who taught in Berlin during the late nineteenth century.
		One simple way to generate this figure is to start with an equilateral triangle, then draw three arcs of circles, with each arc having as its center one of the triangle's corners and as its endpoints the other two corners.
		Like a circle, a Reuleaux triangle fits snugly inside a square having sides equal to the curve's width no matter which way the triangle is turned.

	Reuleaux Collection of Mechanisms and Machines at Cornell University
		Franz Reuleaux created over 800 models of mechanisms to embody his basic machine elements, and he authorized a German company, Gustav Voigt Mechanische Werkstatt, in Berlin, to manufacture over 300 of these models for technical schools to use in teaching inventors and engineers about machines.
		The Cornell Reuleaux Collection contains numerous kinematic mechanisms for rotary and reciprocating engines for both steam and internal combustion, as well as mechanisms for producing mathematical functions, which are related to the early history of calculation machines and later computer engineering.
		At Cornell today, Reuleaux's models are used in the teaching of design, dynamics, robotics, art, and architecture, as well as in historical research.

		The models in Cornell’s collection were designed for research and teaching by the German engineering professor Franz Reuleaux (1829-1905), the founder of modern kinematics and a forerunner of modern design theory of machines.
		Reuleaux created over eight hundred models of mechanisms to embody his basic machine elements and authorized the manufacture of over three hundred of these for technical schools to use in teaching engineers about machines.[2] Cornell’s collection was acquired in 1882.
		STL files for several of the Reuleaux models will be available at the K-MODDL site, allowing users with access to rapid-prototyping equipment to download, 3D-print, and interact with their own fully functional physical replicas.

	DSpace at Cornell University: Item 1813/2712
		This review surveys late 19th century kinematics and the theory of machines as seen through the contributions of the German engineering scientist, Franz Reuleaux (1829-1905), often called the "father of kinematics".
		Extremely famous in his time and one of the first honorary members of ASME, Reuleaux was largely forgotten in much of modern mechanics literature in English until the recent rediscovery of some of his work.
		A unique aspect of this review has been the use of Reuleaux's kinematic models at Cornell University and in the Deutsches Museum as a tool to rediscover lost engineering and kinematic knowledge of 19th century history of machine.
