An iterative temperature field model of cylinder, in which the non-linear steam temperature distributed along axial direction, was got based on two-dimensional transient heat conduction differential equation. Analytical simulation demonstrates not only a rapid solution convergence but a minor error.

Mr Ewbank says:"A butment BB slides backwards and forward in a stuffing box and is so arranged (by a cam or some other contrivance connected to the axle of the small cylinder on the outside of the case) that it can be pushed into the interior as in the figure, and at the proper time be drawn back to afford passage of the piston" Bramah and Dickenson adopted this configuration in 1790 as steam engine and also a pump.

This engine was safer than Savery's engine because it didn't use high pressure steam--the piston is brought up by the beam and not by steam pressure. And, by making the cylinder larger, the power of the engine could be increased considerably.
