On 24-9-2006 I commenced work to build the Triple Expansion Reciprocating Engine of the reheater type, described in the attached note and illustrated with photographs. I finished the project after almost 5 years on the 23-05-2011, with a total of 4,258 hours of work.
This Marine steam engine model illustrates the evolution of the marine engine from the days of the side lever paddle engine onwards. The latest model I have constructed is the one shown in the photos, which represents the latest development of the triple expansion reciprocating engine as exemplified in an engine build by George Clark & North Eastern Marine Engineering Co. 1938 Ltd- South docks Sunderland Wallsend-on- Tiny. I believe it was first installed in a sea-going ship in 1937.
This engine is of the reheater type with balanced poppet valves for inlet and exhaust on HP., and for the IP. Cylinder a balanced flat slide valve.
This engine has cylinder diameters of: HP 28 "- IP47.5" and LP. was a massive 80" with a stroke of 54", and operated at 200 psi-fed with steam from four oil fired scotch fire tube boilers. This type of marine engine as been fitted to the WWII Liberty ships and the SS. Maihare 1 owned by the long established Liverpool ship owners T. & J. Brocklebank. At the photos of this model, at the left is the output end with turning gear and air pump. At rear the reversing mechanism can be seen at far right.
This model although complete in essential working detail, it is not proposed to run this model under steam or compressed air, owing to the difficulty in keeping it clean. It is rotated at a slow speed from an electric motor in the base of the glass case table, with a suitable reduction gearbox.
And it has been produced with modest tools equipment built here at my home.
I worked on this engine from 2006 to 2011 working four hours every day, sometimes much, much more with a total of 4,258 hours.
Dimensions:
Glass Case 30.5 x 34 x 23, Glass case and table 61 x 34 x 23
Total weight: 189 kilograms
