See discussion for model C2. In this model, the link with the sliding pin is fixed. If this were an engine slider crank, the cylinder would oscillate as the piston moved up and down. Such a design for an oscillating steam engine was used by William Murdoch in 1785. Murdoch was employed by Boulton and Watt and made many improvements to Watt's inventions as well as several inventions of his own.
