Locomotive text for engineers and firemen; a complete treatise on the engine, electric head-light and standard code of train rules . ins are operatedrequires, in the interests of safety, the use of a headlightof sufficient illuminating power to throw a shaft of lightfar enough in advance of the locomotive, for the engine-man to observe any obstruction or irregularity of thetrack in time to bring his train to a stop and avoid anaccident. For this reason the qualities essential to thelight are brilliancy and penetration. Electricity fulfills the required conditions better thanany other illuminant and is coming into more generaluse for headlight purposes. At the present time manyhigh speed passenger locomotives are equipped with, elec-tric headlights. A knowledge of their use and operationwill, therefore, be of benefit to every engineman. The electric headlight, complete, consists of an engineand dynamo, and an arc lamp. THE ELECTRIC HEADLIGHT. 291 THE TURBINE ENGINE. The engine, known as the Pyle Compound SteamTurbine, furnishes the mechanical power that operatesthe dynamo, and thus generates the electric current. It. 292 THE ELECTRIC HEADLIGHT. consists of a main casting, having three rows of exhaustor receiving buckets, the turbine wheel with its threerows of buckets, or paddles, the governor and the enginecap or head. Steam Buckets. The buckets of the turbine wheelare all cast solid within the wheel and fit in a recess inthe main casting and just over or above the stationaryexhaust or receiving buckets (Plate 132). The pressureof the steam against the buckets in the wheel is similar tothat of water against the blades or paddles of a waterwheel. Steam Passages. Plate 133 shows a vertical sectioncut through the main casting 101 and wheel 2,y2y fromwhich a good idea of the passage of the steam may beobtained. The steam enters at A, passes through portsf in governor stand 35 (Plate 132), and is directedagainst the first row, a, of buckets, and the wheelmoves forward.
