Model of Beam and two connecting rods with universal motion at their upper ends and connected to transverse hinged links at their lower ends, possibly by James Watt, c.1785.
In this model the horizontal lever, which probably represents an engine beam, is, by two connecting rods, coupled to two beams working in a vertical plane, at right angles to the main beam; universal joints at each end of the connecting-rods give the requisite freedom. It may date from the period c.1784 when engineers James Watt was establishing the best way to connect a vertical piston-rod on a beam engine to the end of the beam above.
