The Sarrus linkage, invented in 1853 by Pierre Frédéric Sarrus, is a mechanical linkage to convert a limited circular motion to a linear motion without reference guideways. The linkage uses two perpendicular hinged rectangular plates positioned parallel over each other. The Sarrus linkage is of a three-dimensional class sometimes known as a "space crank", unlike the Peaucellier-Lipkin linkage which is a planar mechanism.

Although Charles-Nicolas Peaucellier was recognized for being the first to invent such a straight-line mechanism, the Sarrus linkage was invented earlier, it went however largely unnoticed. [1]
