Oil Field Stover

| February 2005

Two good friends of mine, Dave and Kent Park of Bluffton, Ind., recently showed me an engine they were able to obtain from the oil well lease it was on near Cambridge, Ohio. Their great engine find is another example of an engine make that was put into service in the oil fields, but is not normally associated with the oil industry.

This 5 HP Stover engine was attached to a single well pump jack. The serial number, TD-273127, on the Stover tag indicates it was built in 1941, according to the serial numbers listed in the back of C.H. Wendel's book, Power of the Past Vol. 3. It is one of the enclosed-style "CT" model engines.

The engine had been converted from magneto to hot-tube ignition, a common practice in the oil fields where operators could utilize the wellhead gas for ignition and engine fuel. The hot-tube and its chimney were attached directly to the spark plug hole.

The lease operator reportedly pumped it only four hours every Saturday during the last years of the well's production. He had provided it its own little "house" for protection from the elements when it was not in operation, which consisted simply of a panel of corrugated steel with a couple of notches cut into it for the pump jack that was laid directly on top of the engine.

In the photos, you can see that three of the bits possibly used to drill the well have been put to use as a counterweight for the pump jack.

Thanks goes to Dave and Kent for sharing their interesting find with us. I would encourage our readers to share with us their discoveries in the oil fields.
