It will be seen as the valves stand in the figures that the steam passing down H into the valve box E, and down the uncovered aper- tures to communicating pipeC 1, finds the upper aperture stopped up, it consequently makes its way through the lower one and forces up the piston, at the same time the upper valve on the other side of the cylinder is open, and a vacuum being formed in the condenser, it ex- hausts G, under F, the branch to and the communicating pipe C 2, and the portion of the cylinder above the piston. If we wish now to reverse the motion, we have only to push the valve F to the other end of the box, as represented bv dotted lines in fig. 3, the branch pipe, and C 1 is open to the condenser, and the steam passes down the branch into C 2, and presses down the piston. The mode of operation will I think be now understood. Fig. 4 is a view of the valve F, as proposed for a pair of engines, showing the midfeather to separate the exhausts or eductions to the respective condensers. The branch pipes to the other cylinder are shown broken off. There is another use of the valve F, it is a perfect regulator or throttle valve, to stop or regulate the engine by; for it is so constructed tliat supposing the steam to be shut off by it when running either way, still the exhaust apertures remain entirely open. The simplicity of its action, and its doing away with a considerable number of small moving parts consequent on reversing and management in general, by the present methods are its recommendations, not to mention that one man could manage a pair of the largest engines which have yet navi- gated the ocean, better than 4 or (i, or even 1(J men, to jome of our Fig. 2.—Section of Fig. 3.—Elevation of Cylinder and Section of Please note that these images are extracted from scanned page images that may have been digitally enhance
