The steam cylinder has the appearance of the cylinderfamiliar to every one, as seen on ordinary plain slide-valveengines. Its valve chest is placed at the end nearest thecrank, and the ports and passages are carried as in thoseengines. The valve stems have no stuffing boxes, but passinto the chest through unusually long and carefully fittedholes, in a hub, made about five one-thousandths of an inchlarger than the rod inside the Babbitt metal bushing,for a length of six diameters or more. The hub isloose in the hole in the end of the valve chest, and ispacked at the ends by a washer fitted on a flat seat on theinside. The piston-rod is similarly fitted. The crosshead is a very long casting which overruns the.
