I became interested in old one-lunger engines when I saw three of them rusting away in a field at a Southern Maryland farmhouse. I received one - a 3 hp McCormack Deering (green) - as payment for making 42 shutter dogs for the farmhouse. I got the other one - a 5 hp Hercules (blue) - by just asking for it. I really don't know what happened to the other one-A 3HP Stover??? |

Getting ready to take the engines to a show. Notice the feed grinder which will be driven by the engines. I borrowed the 49 Studebaker truck from a friend. | ![]() |

This engine generates 3 horsepower at 600 rpm. I have adjusted the governer for a speed of 400 rpm. The engine weights 465 lbs. It is designed to start on gasoline and then run on kerosene after it warms up. The engine's operating temperature is ~ 212 deg F.
Water is poured into the top hopper for cooling. Shown are Henry and the McCormack Deering grinding corn at a Southern Maryland show. Notice the smoky kerosene exhaust. |

This engine generates 5HP at 500 RPM. It weights=1000 lbs. This engine is also designed to start on gasoline and then run on kerosene after it warms up. I converted this engine from throttled governed to "hit and miss" (Exhaust valve governed). Suprisingly, I have very few pictures of it working. The hopper is filled with water for cooling. This was probably the third time that I had it running. |

This is what this engine looked like when I found it. The white is dirt and shows how far it was in the ground when I found it. The green is moss growing in the rust. It had no mixer (carburator) or magneto (used to provide the spark) and the piston and both valves were frozen (rusted) tight. The comment was made "..you'll never get that thing running".
