Présentation de l'éditeur

We devote a few pages to the history of Compound Engines; a history heretofore little known, but which we are able to make complete by means of documents that enter into minute details, and which contain matter instructive and interesting, while they shed light upon subjects heretofore obscure. The idea of employing the expansive power of steam is generally attributed to James Watt. This is shown by the evidence of a patent of Jan. 5, 1769, No. 913. The process consisted in arresting the introduction of steam a little before the termination of the stroke of the piston, thus reducing the pressure at the moment of the reverse stroke ;it was not until sometime after that it was perceived that a certain quantity of steam was thus economized.
