- Application: Pump, Steam engine, water motor. This device was invented by one Behrens, a partner in the firm of Dart and Co. of New York, around 1867. This firm produced at least one in the form of a 12 hp steam engine. It can be used as either a pump or a water motor, because surface contact exists between the mating surfaces and leakage can be kept low. The profile of the surface art the end of the moving members is that of a curtate epitrochoid. When a circle rolls upon the outside of a fixed circle, a point on the radius of the rolling circle (but not on the circumference) describes a curve called the epitrochoid. A curtate epitrochoid is a small section of the whole curve. [H. Roehl 1950-00-00]
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. - Repository:
