Simplex

SIMPLEX,  OLD STYLE

No doubt that this is the single valve engine that William J. Innis designed for Oil Well Supply, of Oil City, PA in 1892.  The cam holds the one main valve open for a complete revolution of the crankshaft with check valves performing the intake and exhaust functions.  It has a ported cylinder with hit and miss governor.  It pumped wells north of Marienville, PA.

Western

WESTERN

This 30 hp Western was built in Los Angeles, CA and used by Standard Oil to drive a compressor.  California engines always seem small for their rating and this is no exception.  It was built about 1915 and represents the later Western style.  It features both valves being power operated and a hit and miss governor.  It is magneto and spark plug ignition.

Bruce McBeth

BRUCE–MACBETH

This 90 hp four-cylinder engine was built by Bruce-Macbeth of Cleveland, Ohio about 1906.  There were 14 such engines in the power house of Pierce Glass Co. of Port Allegheny, PA driving low pressure compressors to blow the bottles into the molds.  They operated into the mid-1970s when this one came to the museum.  It features a vertical governor and overhead cam shaft and runs so smoothly. 

General Electric

GENERAL ELECTRIC

This is a four-cylinder, 50 hp GE engine direct coupled to a generator.  These were built in the early 1900s and several survive.  This engine was used on the Erie Barge Canal in New York state to provide direct current to open and close the lock doors.  It is extremely well finished with lots of brass work and powers some lights here.  It came to the museum in the late 1970s.
