Build of a small horizontal Steam Engine

Standard internal diameter will easier standard automatic engine piston ring. The ends are threaded lathe, size of standard pipe-thread, while maintaining the two conical hardwood blocks, the threaded mandrel and a healthy lead at the ends of the cylinder with the nuts and washers. Standard mandrels for this purpose, if any, are more convenient. Rectangular plate (A), which supports the rear end of cylinder is also bored and threaded lathe, using independent Chuck four fork to hold it. This plate, rear head and copper cylinder-they are attached together and all similar holes in each hole drilled at one time. To make the stuffing, with a length of 2-inch cast-iron genus is drilled to fit piston rod, then appeared at the front, with a width of 625. contains the packing and threaded to fit the gland nut. Piece then ends on the lathe, and outer threaded to fit in the cylinder. After the break, wrench flats are ground on the shoulder. Gland nut is made of brass bar stock, threaded to fit the stuffing, as well as the hexagon grounds of it. When the parts are assembled with packing the place, piston and Rod must work smoothly, but stiffly in the stuffing and cylinder and almost real when ports are closed. The piston is made of cast iron and undercut to reduce weight, as well as in Fig. Front head tube CAP, the outer part of which is to provide more enjoyable type, turned and drilled and threaded to receive the stuffing, Figure 2. The distance between the end of the codend steam port and the inside of the CAP, when screwed the houses must be much less than tha shown, not over 1/4 contains, for the efficiency and the same at the rear end. When the CAP was permanently screwed to the cylinder, one side is flattened, as shown, the Shaper or mill, and steam ports established and trained. Will be decided advantage to make these ports as much larger than is possible, as the effectiveness with the ½-inch ports is well below what might have been.  here
