TRIPLE COMPOUND ENGINES.

[Footnote: Paper read before the Institution of Naval Architects, March
27, 1885.]

By Mr. A.E. SEATON.


My attention was first called to the modern triple compound engine by the
published reports of the trial trip of the yacht Isa, and in it I plainly
discerned the germs of a successful new type of engine; but it was not
until I had seen the engines of the screw steamer Aberdeen erected in the
workshops of Messrs. Robert Napier & Sons that I became convinced that it
was the engine of the immediate future. It is, however, due to the
farsightedness and enterprise of Mr. C.H. Wilson, M.P., that I was
enabled to try the merits of the new system and compare it with the old.
Mr. Wilson had already viewed the triple compound engine with more than
ordinary interest, and it required little persuasion on my part to allow
the company to which I have the honor to belong to construct a triple
expansion engine in lieu of the ordinary compound for one of four sister
ships which it then had in hand for Messrs. Thomas Wilson, Sons & Co.,
