Peaucellier cell
(pəʊˈsɛljeɪ sɛl)
[From name of the inventor, Lieut. Peaucellier, 1864.]
A plane linkage consisting of a jointed rhombus fixed by three bars to two distinct centres, so that when it oscillates about these, its angle opposite to the centres describes a straight line, thus developing a rectilineal out of a circular motion.
