APRIL, 1899. AMERICAN ENGINEER AND RAILROAD JOURNAL. 138 ECLIPSE REDUCING VALVE. For Locomotives and Marine Service. This reducing valve is simple and Is making a name for It-self on several railroads and steamships. Steam enters thevalve through the pipe shown at the right hand side of the en-graving. The piston is loose for vertical movements, and inthe absence of steam pressure it drops to the bottom of thecasing and leaves the valve passage open. As the steam pres-sure accumulates in the outlet connection, at the left, it actsuj)on the piston, forcing it up into the cylinder on top of thevalve and the pressure of steam in the outlet side is governedby the tension of the spring in the housing above its screwed down this spring holds the piston open untilbalanced by the steam pressure, whereupon the valve The Eclipse Reducing Valve. It is stated that the outlet pressure is not affected by varia-tions in the boiler pressure. One superintendent of motivepower has remarlted that it was so simple that he was almostafraid to trust his men with it. There are but four workingparts, the valve, valve pin, spring and screw. This valve isnow in use on the Chicago Northwestern, the Cincinnati, Ham-ilton & Dayton, the Atchison, Topeka & Santa Fe, the BigFour and several other roads, and also on ships of the Minne-sota Steamship Company. It is manufactured by The JohnDavis Co., 51 Michigan Street, Chicago. STUPAKOPF ON WIRE GAUGES. Mr. S. H. Stupakoff read a paper on wire gauges before theGerman-American Engineers Society at Pittsburg, Pa., onMarch 22, 1S99, on which occasion every known gauge receivedattention from the speaker, who did not fall to hold up as anobject lesson those familiar representations that are parodieson the name of gauge.
