White engines have an unusual uni-flow design with a power activated secondary intake valve. They utilize a crosshead slide to guide the piston and transfer power to the crankshaft connecting rod.
This particular engine is one of only five known to have been built. It pumped five oil wells on the high ridge west of the intersection of Oil Creek and the Allegheny River at Oil City, Pa. - just about five miles from where it was built. The wells were located at the headwaters of the Charley Run, which flows into the Allegheny River just south of the old Joseph Reid factory. The engine was removed from service in March 1980.
The photos show the engine as it appeared in its working clothes. This engine looks very close to the way it looked in the oil fields of Western Pennsylvania: well used and very well lubricated.
