It is to be noted in Fig. 6,that the frame crank case 2 is connected with the crosshead frequently has an opening into the sub-base, thus permitting theoil from the crosshead, guides, and crank to drain into a suitablereceptacle in the sub-base, from which it is taken by means of a draincock conveniently located in the side or end. The crank is enclosed.

Cylinders. The cylinder 5, Fig. 5, is one of the most impor-tant parts of the steam engine, for it is in the cylinder that theenergy of the steam is converted into useful work. The cylinder iscircular in section and is attached to the bed by means of a numberof bolts. It is made of close grain, gray cast iron. The castingof the cylinder should be done with great care^ so as to insure acasting free of blow-holes or other defects. Fig. 8 illustrates the cylinder in cross section as well as show-ing its contained parts. The cyUnder barrel 1 is accurately bored STEAM ENGINES 11 and fitted. Inside of this barrel the piston 2 is driven back andforth by the steam, which is admitted alternately on one side andthen on the other through the ports 13. The
