I have just been given a set of drawings on 13 sheets, probably dye-line prints, for a very impressive horizontal Corliss engine model, probably a mill engine. Despite their susceptibility to fade in daylight, all sheets are in extremely good condition. They were drawn by Arnold Throp using Imperial dimensions and Superscale Ltd has been crossed out and replaced by Fleet Model Services. They were produced in March 1981 and all the drawings were 'approved' by a T.Fleet.
The flywheel is 9.75” in diameter with a face of 2” and to include the condenser the engine is about 28” long. It is drawn with a Hartnell Governor. Interestingly the sheet which shows the crankshaft gives five versions:
-
Shaft for single cylinder engine and all corliss compound.
-
Shaft for tandem compound with S.V. (Slide Valve ?) L.P. (Low Pressure?) cylinder.
-
Shaft for cross compound with S.V. L.P. Cylinder.
-
Shaft for cross compound all Corliss.
-
Shaft for twin tandem and four cylinder triple expansion, this component in model form is 12.75” long!
It seems likely that the drawings may include details for more than one version, e.g. one sheet includes 'tie-bars for tandem cylinders'.
Is there anything known about this model? Have the words and music appeared in the model engineering press? Are there images of a completed model? Are there castings available? It is way beyond my abilities, even at twice full size, the trip gear and dash pot arrangement looks fearsomely complicated. However, I would find it interesting to know a little more about the pedigree of the model. Thank you.
