The document discusses various inversions of mechanical linkage configurations including the four bar chain, single slider crank chain, and double slider crank chain. Specific examples of mechanisms that incorporate inversions of these linkages are provided, such as the beam engine, coupling rod of locomotives, Watt's indicator mechanism, pendulum pump, oscillating cylinder engine, and rotary internal combustion engine. Elliptical trammels, Scotch-yoke mechanisms, and Oldham's coupling are also mentioned as incorporating inversions of the double slider crank chain.
