Trouble with the Evan Leigh Engine. Gear Patterns from the Whitworth Works. First Order for a Governor. Introduction of the Governor into Cotton Mills. Invention of my Condenser. Failure of Ormerod, Grierson & Co. The Evan Leigh engine was not quite ready to be started when I left England. On my return I found an unexpected trouble and quite an excitement. The engine had been started during my absence, and ran all right, but it was found almost impossible to supply the boilers with water. Two injectors were required, and two men feeding the furnaces, and everybody was agreed that the fault lay with the engine. The boilers were a pair of Harrison boilers, from which great results had been expected. These were formed of cast-iron globes, 8 inches internal diameter, with 3-inch necks, held together by bolts running through a string of these globes. They were an American invention, and naturally Mr. Luders (who was introducing them in England) and I fraternized. I felt greatly disappointed. I did not then see Mr. Leigh, but had the pleasure of an interview with his son. This young gentleman denounced me in good Saxon terms as a fraud and an impostor, and assured me that he would see to it that I never sold another engine in England. He knew that the boilers were all right. His friend Mr. Hetherington, an extensive manufacturer of spinning and weaving machinery, and who had taken the agency to sell these boilers, had had one working for a long time in company with a Lancashire boiler, and there was no difference in their performance. He finished by informing me that the engine would be put out as quickly as they could get another. I put an indicator on the engine, and show here the diagrams it took. I could not see that much fault was to be found with those diagrams. Old Mr. Leigh, after looking at them, said nothing, but he did something. He went to an old boiler-yard and bought a second-hand Lancashire boiler, had it carted into his yard and set under an improvised shed alongside his boiler-house, and in two or three days it was supplying the steam for my engine, and all difficulties had vanished. The consumption of steam and coal fell to just what it had been calculated that it should be, and everybody felt happy, except my friend Mr. Luders, who, notwithstanding his grievous disappointment, had never gone back on me, and young Mr. Leigh, who owed me an apology which he was not manly enough to render. Repeated efforts were tried to make the Harrison boilers answer, but the result was always the same, and they were abandoned. [Illustration: Diagrams from Engine of Evan Leigh, Son & Co.
