[Vol. XXVII. No. 6. A VERTICAL ENGINE USING FORCED LUBRICATION The B. F. Sturtevant Company, of Hyde Park, Mass., hasjust brought out a line of new vertical high-speed automaticengines, known as class VS5. A. system of forced lubricationand the complete enclosure of the moving parts provide forcontinuous operation for weeks at a time without attention,ajid insure perfect reliability even in the hands of the un-skilled. These engines are especially designed for the drivingof direct-connected generators. Lubrication for all bearingsis provided by a submerged oil pump in the base. This pumpis operated by the crankshaft, and acts against a pressure of. VERTICAL ENGINE USING FORCED LUBRICATION from 10 lbs. to 20 lbs. per square inch. Centrifugal oil guardslocated on theshaft just where it passes through the casing,together with the enclosing frame and the watershed partition,insure perfect cleanliness and absolutely prevent the escape ofthe oil, which is continuously repumped tothe bearings. Another important and dis-tinctive feature of this engine is a watershedpartition, which prevents water from the pis-ton-rod stuffing box mixing with the lubricat-ing oil in the case, and at the same time makesimpossible the passage of oil from the enclosingframe to the interior of the cylinder. The pis-ton-rod stuffing box may be readily adjustedwithout opening the case. This watershedpartition forms a part of the enclos-ing frame, which protects the parts fromdirt and accident, insures economy and elimi-nates the necessity of frequent attention;but the removable oil-tight plates or coversmake the parts as accessib
