Excerpt from The Mechanics' Magazine, Vol. 64: January 5th-June 28th, 1856 Fig. L is a plan of the improved engine with the two cy inders, the pistons, and the air heating apparatus in section; and fig. 2 is a side elevation, with one of the cylinders, the piston, and the air-heating apparatus in section, to exhibit the internal arrangement. The engines are single actin and two are connected by a crank shaft, the two cranks being placed at an angle of 180 so that, while the piston of one engine is being impelled by the tension of heated air, the piston of the other is making its return stroke, and vice send, and as the two engines are identical in construction, the description of one of them will answer for the two. The manner of connecting the two, and the effects resulting there from, will be subsequently described. The following description is by Captain Ericsson's agent.
