The Miller

Manufacturer: Miller Gas Engine Co., Springfield, Ohio
Year: 1919
HP: 50

This 50 HP Miller single-cylinder gas engine was
originally installed at the Roth Milling Co. of Prospect, Pa. in

It is believed that this is the last new engine shipped by the
Miller Gas Engine Co. of Springfield, Ohio.

It is a 4-cycle, throttle-governed gas engine having a 13-inch
bore and 20-inch stroke. Shipping weight is 13,500 pounds.
Curiously, this crosshead-style engine was actually built in 1919
but not sold until 1947.

After a 1956 clutch failure in the flour mill, the engine sat
dormant until Ellis Wellman of Chardon, Ohio, removed and
refurbished it in 1968.

The 50 HP Miller is presently owned by Bill Hazzard of King of
Prussia, Pa., and is on loan to the Coolspring Power Museum.
