This is shown in Fig. 5. The Richmond has an automaticstarting and compounding device, con-vertible into simple engine at will bythe operation of an H. P. exhaust (emer-gency) valve only, affecting the pres-sure in an exhaust chamber separated,except by small vents, from the re-ceiver by the extension of a piston onthe stem of the intercepting valve whenin compound position. In changing tosimple, this chamber is exhausted,whereby the intercepting valve be-comes unbalanced, closes, and cuts offthe L. P. steam chest from the receiverbefore or at the moment the exhaustof the latter takes place, and at thesame moment live steam, at reducedpressure, is admitted to the L. P. steamchest. In changing to compound theH. P. exhaust valve is closed, whereby. Complete Booklet on Application L. J. BORDO CO, PHILADELPHIA, PA.

Thus it isseen that in this system there is nodrop in the pressure at the changeeither into simple or into compound work-ing of the engine, and a temporary in-crease in power of 20 per cent, can behad without risk of stalling under thechange, however slow the speed, andhow often it may be required to changeon a grade, as is indicated in Fig. 6. The Schenectady compound of 1896operates in all respects similar to theRichmond, but it is not provided withexhausting balance chamber and must,therefore, in the same manner asRhode Island, empty the receiver be-for the
