This mammoth engine is one of the five 175 hp models built and the only one surviving.  Built in Philadelphia in 1925, it weighs 25 tons and has 109 inch flywheels.  It was installed in the Brookville, PA, Water Works and it saw active service until 1946.  Put on standby, it was finally removed in 1969.  It drove a triplex water pump.

Tour the reconstruction of the 175 hp Otto engine and Deane pump.



This is the massive 14 x 12 bore and stroke Deane Triplex water pump that the Otto drove.  The wide flywheel on the engine also drove a centrifugal suction pump in the basement and the Deane delivered the water to the municipal reservoir.  It provided Brookville with 1.5 million gallons of water daily from North Fork Creek.  It was built by Worthington of Holyoke, MA in 1925. 



This engine, built by Etna Machine of Butler, PA, is about 7 hp.  It is a two-cycle, with original paint, and dating about 1910.  It powered Berry’s second machine shop in Petrolia, PA after he returned from Pittsburgh.



This twin-cylinder, vertical, 60 hp engine is direct coupled to a DC generator.  It was built by Westinghouse Machine Co. in East Pittsburgh, PA in 1903 and installed in Blaw-Knox Rolls of Wheeling, WV.  This firm made steel mill rolls and the unit was kept on standby to provide power to empty the ladle of molten metal in case of emergency.  We also have their 90 hp three-cylinder unit from another installation which is under restoration at this time.  Designed by Edwin Ruud.
