The Newcomen model arrived at last and was promptly repaired, but was not successful when put in operation. Steam enough could not be obtained, although the boiler seemed of ample capacity. The fire was urged by blowing and more steam generated, and still it would not work; a few strokes of the piston and the engine stopped.
He had often pitted his wits against the most famous detective inspector, the great Benton, who had achieved so much notoriety in the Enfield poisoning case, the Sunbury mystery in which the body of a young girl shop-assistant had been found headless in the Thames, the great Maresfield drug drama of Limehouse and Mayfair, and the disappearance of the Honorable Edna Newcomen from her mother's house in Grosvenor Gardens.
The most interesting person connected with Dartmouth of late years is Newcomen, the inventor of the steam engine. He carried on business in the town as an ironmonger. All honour is due to his memory, although others perfected the work which he commenced.
In the year 1760, James Watt, who was by occupation what is now known as a model-maker, and who lived in Glasgow, was called upon to repair a model of a Newcomen engine belonging to the university. While thus engaged he was impressed with the great waste of steam, or of time and fuel, which is the same thing, involved in the alternate heating and cooling of Newcomen's cylinder.
He published the result of his observations in his 'Century of Inventions, which formed a sort of text-book for inquirers into the powers of steam for a time, until Savary, Newcomen, and others, applying it to practical purposes, brought the steam-engine to the state in which Watt found it when called upon to repair a model of Newcomen's engine, which belonged to the University of Glasgow.
His predecessors, the Marquis of Worcester, Sir S. Morland, Papin, and others, only produced outlines which required to be filled up to make them workable." I must not detain you much longer before I proceed to the great Watt, but I will just name Newcomen, who invented an engine with a cylinder, and introduced a beam, to the other end of which he fixed a pump rod like a common or garden pump.
The primitive steam-engine, as Newcomen conceived it, required the presence of a person exclusively employed to turn on and off the taps, either to let the steam into the cylinder or to throw the cold spray into it in order to condense the steam.
Having a cylinder closed at the top, while the Newcomen cylinder remained open, it was as easy to admit steam at the top to press the piston down as to admit it at the bottom to press the piston up; also as easy to apply his condenser to the steam above as below, at the moment a vacuum was needed. All this was ingeniously provided for by numerous devices and covered by the patent.
"The battle of Newcomen Junction." What of it? In railway circles, not only in Ireland but in England and Scotland too, it caused some talk at the time and no little amusement.
The real introduction of steam as a factor in man's daily work was effected later on, partly by Savery himself and partly by Newcomen, and above all by James Watt.
