RECIPROCATING STEAM ENGINES the top end usually being forked in large engines and attached to the crosshead with bearings so that the crankpin is free to turn as the crank goes around. In the drawing, the steam enters at the center, and this is known as an inside valve. It is impossible This engine was designed following a number of requests for a simple machining project. There are many other oscillating steam engine designs, and some are much simpler, using plumping fittings and wire links etc However because this engine was designed to be a machining project, bar-stock was used for all the parts. cellent exercise in steam-engine con-struction, and is deservedly popular. sions are given on the drawing. Both engines are intended to be built from castings, though fabrication of The height of the cylinder, cross-head and main bearing centres must all be exactly the same, and careful has played a historic role in steam-power development. The engine is a double-acting drawings are for the finished parts. If pat- terns are made, an alloance of 3/32" must crosshead. With the piece on a mandrel, The figure shows the part drawings of a steam engine crosshead. The crosshead, with the help of slide block 4, reciprocates between two guides provided in the engine frame. The gudgeon pin 3, connects the slide blocks with the crosshead block 1.
