What it is
A spatial six-bar linkage that converts limited circular motion into pure linear motion without guideways, invented by French mathematician Pierre Frédéric Sarrus, predating the better-known Peaucellier linkage.
What it led to
- an early precedent for exact straight-line mechanisms
- applied in presses, mechanical jacks and precision mechanisms
- a reference in mechanism theory and kinematics
