If the engine is started simple, theregulator being as in Fig. 2, it will con-tinue to work simple; but by changingthe regulator to either the position ofFig. 3 or Fig. 4, it will automatically goto compound, on account of R closingand being held on its seat, and the pres-sure in C accumulating to about 20 percent, of that going to the H. P. cylinderat the time as explained, in the case of theregulator being in the position shown inFig. 4. To prevent, as far as possible, the effects.

P. cylinderat the time, whenever the engine is work-ing simple. When the regulator F is inthe position shown in Fig. 2, the cham-ber in the end of 7, back of R, is in ex-haust through the ^-inch pipe and ports9 and 7 to the atmosphere, and R will re-main as shown (open), consequently theengine in that case will work simple; theexhaust going out through S S lo theL. P. cylinder exhaust passage, Fig. i. If the regulator valve is moved to theposition shown in Fig. 3, steam will thenflow through the pipe 9 9 into T, pushand hold R to its seat, and at the sametime W will be in exhaust, and as R is is then opened, steam will flow in at A,and as both ports 8 and 9 are uncovered,the chambers T and IV will be filled andthe val
