Pattin Brothers Oilfield Engine

This odd rig was once common in the oilfields of the eastern US, and there may still be a few in operation out there somewhere. This engine would have been set in a powerhouse on a knob or point, with rod-lines radiating out to oilwells, where a bellcrank would change the horizontal reciprocation to vertical,operating the rods and pump in the oilwell tubing. This is a small engine; I think it is just eight horsepower, and was meant to operate up to six wells of 1000 feet.
