Root and Van Dervoort "L" Line "Triumph" 12hp.

Built by Root and Vandervoort Engineering Co. East Moline, Illinois in 1914.

Engine No. GL46667

There are six known surviving 12hp R&V engines. Five are "Triumph Line" engines (four 'L' line and one 'R' line engine) and one sideshaft engine. My engine is now fully restored and will be attending a number of rallies this year. It is a very smooth running engine and is very reliable.

The "L" Line engines were available in 1hp, 2hp, 4hp, 6hp, 8hp, 10hp, and 12hp (of which mine is an example).

Some 12hp 'L' Line specifications: RPM:325; Flywheels: 40 inches diameter, weight 385 pounds (143.6kg) each; Piston rings: 5; total shipping weight: 2300 pounds (858.5kg).

NEWS: GL46667 finally returned to life at 8pm on Thursday 6th September 2001. It started fairly easily (after about 10 turns) picked up speed, and governed perfectly. It ran for about 20 minutes in total (after a couple of stops to check things). There are no unusual knocks or noises and it runs very smoothly.

This 12hp Triumph (GL34036) belongs to David Miller in the USA. This is a straight petrol engine and also has the Wizard magneto mounted on the ignitor. Note it has a square pushrod to allow for the Wizard.

This is an impressive way to carry a 12hp R&V home.
