Harvey Wahl, R.R. 1, Box 61, Dundee, Minnesota 56126 is the proud owner of this 7 HP Lennox engine, which he shows yearly at the Butterfield Steam and Gas Engine Show. Look inside for his story.
I bought this 7 HP Lennox gas engine about 12 years ago at a gas engine auction near Ramona, South Dakota. Although the engine was basically complete, the hot tube ignition system and the carburetor, gas tank and gas lines were missing. After cleaning and painting the engine, I built the engine trucks on which the Lennox is mounted.
I found a picture of a Lennox gas engine in an advertisement in a 1902 edition of The Farmer magazine. Using this picture, I mounted a water tank and a gas tank which closely resemble the configuration shown in my old Farmer magazine. I was also able to fit the engine with a Lunkenheimer carburetor to complete the fuel system.
When I bought the engine, someone had previously drilled, tapped and fitted the intake chest with a spark plug. Realizing that it would be nearly impossible to replace the hot tube ignition system, I decided to fabricate an ignition system using the spark plug tapped into the engine. With the piston turned on the compression stroke to dead center, I mounted a small contact pin on the side of the timing gear. I also mounted an insulated spring contact on the side of the engine which enabled me to time the engine. Using a Model T buzz coil and a battery, I was able to complete the ignition system. After a few turns of the flywheels, the Lennox fired and was running once again. Although the engine shows a lot of wear indicating it was used extensively, it runs very well and is shown annually at the Butterfield Steam and Gas Engine Show.
The Lennox Machine Company was established by David Lennox at Marshalltown, Iowa in 1880. Lennox engines were first marketed around 1894. The engine line grew to include 20 sizes ranging from to 30 HP. These included air, hopper, screen and tank cooled styles, but as with many other makes of engines, very few exist today. Among other items manufactured were grinders, scales, electric light plants, and washing machines.
I only know of one other Lennox engine still in existence today. I would be very interested in hearing from anyone who owns or knows of existing Lennox gas engines, literature or other products built by the Lennox Machine Company.
