The creation of linkages to produce straight-line motion was an important engineering as well as a mathematical problem of the 19th century. This eight-link linkage was one of the first to produce exact straight -line motion and was independently invented by a French engineer named Charles Nicolas Peaucellier(1832-1913), and by a Russian mathematician named Lipmann I. Lipkin (1851-1875). It was used in various pressure indicators in steam engines as well as in machine tools. This mechanism is a good example of path generation linkages. The linkage output was obtained for different link lengths (adjustments) or phases.
Adjustable mechanisms have gained more interest from researchers recently. Using the adjustable peaucellier mechanism allows us to get an exact straight line path generated with different slopes (angles).
