1902 Knox Runabout: Our Newest Acquisition

We just acquired a unique automobile for the museum--a 1902 Knox Runabout. We have wanted to add a Knox to our collection for some time, so this news is very exciting. Our collection's theme focuses on early American automobiles with significant or unusual technology and/or design features, and the Knox certainly fits.


Harry Knox chose to make an air-cooled, one-cylinder engine for his first automobiles. Most makers of air-cooled cars at the time used fins cast integral with the cylinder block for cooling. Because this only worked for light-duty engines at the time, Harry Knox covered his cylinder barrel with over 1,000 two-inch pins. Each pin has a spiral-knurled surface, which reportedly increased the surface area for cooling by 100%. The combination of pins and a fan worked well to maintain a normal engine temperature.




You can see from the photos why the Knox earned the nickname of "Old Porcupine," although some thought the engine more closely resembled a hedgehog.





Our Knox is being shipped from its former home in Pennsylvania out to California for some TLC by Allan Schmidt's Horseless Carriage Restoration in Escondido. I'm not sure when it will make it to Fairbanks, but I want to to be the first to ride in that scary front passenger seat!
