Here are two views of the 1914 125 HP Miller gas engine No. 1419 as we found her last year after following a lead kindly supplied by Mr. Howard Yoder.

 

She is a side-by-side twin with on flywheel in the center, and one of the few four cycle engines to use crossheads. She runs on natural gas and uses Watts pressure-balanced exhaust valves, Bosch high tension rotary magneto, Massey-Jahns throttling governor head, and White Star oil filter. Power cylinders have a 15-inch bore and 23-inch stroke; the flywheels are 82-inches diameter with a 20-inch face. A 16-inch leather belt ran on its rim.

 

This engine was built in 1914 by the Miller Improved Gas Engine Co. of Springfield, Ohio, and powered the Ziegler Milling Co. in Bucyrus. Everything was five feet below ground level, so it took lots of winching as well as five truck loads to get her home. All major parts have now been moved to the Kinzers show grounds, and we plan to begin erection this summer. Ellis Wellman and I each have a 50 HP single cylinder Miller too.
