Description

1842 Nature Print Steam Engine Another Fine Quality Print from Martin2001 Print specifics & condition at the bottom. Illustrations depicted: ROTARY ENGINE: This is one of that class called the rotatory steam-engine; a class comprehending many varieties, of which we hear much and see but little. The engine is here given as an illustration of this very unsuccessful class of engines, by one of its least exceptionable examples. It has actually been in use for some years, being frequently employed to turn the machinery of a large establishment. We have seen it working smoothly and well. Yet we have not been able to recognize in it any reason for giving it an equality, much less a preference, in comparison with the common engine. It can be reversed in the same way as a common engine. It was invented by Mr Yule of Glasgow, by whom it was patented, and is still in the works of Thomas Edington, Esq., at Glasgow. SSS is a double steam-pipe, either branch of which may be employed according as the engine is to go forward or backward. AA is the cylinder firmly fixed on a stone foundation, and in its centre is an axis XX, upon one side of which and eccentric to the cylinder is an inner cylinder or barrel turned quite true, and fixed to revolve with the axis X, and so to form the piston P, which is to receive and give out the force of the steam. RR furnishes the point d'appui, the surface of reaction, which resists the force of the steam and forms a. fixed obstacle. It is a flat slide or sluice, (see fig. 5,) resting on the barrel piston P, and maintained by guides always in a vertical position. It passes into the cylinder through rectangular stuffing box, and is raised and depressed by a small eccentric pin xx, so as to remain always upon the surface of the piston drum. All the working surfaces are rendered steam-tight by metallic packings. EEE is the eduction passage into the condenser or the open air, DD are slide-valves to be reversed when the engine is to go backwards. On the revolving axis of the piston X are toothed wheels, gg, working other two, gg, which have a common axis zz, carrying a fly-wheel, and driving the machinery to be worked by the engine. Fig 6. shows the ports at DD. Fig. 7 shows the guides of the slide RR.
