Engines

1908 15hp Pattin Bros "Ekonomy" bump start.

This is a 1908 Pattin Bros oilfield engine that was originally from the Pennsylvania oil fields that runs off natural gas and uses hot tube ignition. In the oilfields, natural gas was readily available and provided a cheap source of fuel and ignition. The natural gas allows for ignition by heating a "hot tube" that is threaded into the engine's head and housed inside a larger pipe. In the video below, the hot tube is inside the pipe with flames coming out and is heated red hot to ignite the air/gas mixture inside of the engine cylinder when it reaches a certain compression. 

Pattin Bros Intake Valve Assembly

The natural gas is taken in through the holes in the valve seat. These holes must be sealed when the intake is closed. 

Engine Lineup

This image displays a large part of my engine collection. To the right is my lineup of Fuller and Johnson model Ns. In my lineup, I have the 1 1/2, 2 1/2, 3, 4, 5, 6, 7, and 9 horsepower engines. The 1 1/2 horsepower fuller and johnson shipped at 265 pounds, and the 9 horse shipped at 1530 pounds without a cart. The 6 horsepower engine is a "People's Price" engine which was the precursor to the N series. Less than 1000 of these "People's Price" engines were made. To complete my lineup, I need the 8, 10, and 12 horsepower model N engines. Pictured to the left are some of my other engines - DeLaval horizontal and upright engines, a Fairbanks Morse dishpan, a 4 horsepower Novo upright, a 3 horsepower Hercules, and a 3 horsepower Fuller and Johnson model K. Also pictured to the left is a 3 horsepower Fuller and Johnson model DE engine. This engine was built in 1912 and was a series that came before the model N.
