Hart's inversor is a mechanism that provides a perfect straight line motion without sliding guides.[1]

It was invented and published by Harry Hart in 1874–5.[1][2]

It can be used to convert rotary motion to a perfect straight line by fixing a point on one short link and driving a point on another link in a circular arc.[1][3] (The fixed points and driving arm make it a 6-bar linkage.)
