MILLER, 80 HP
This engine was found in West Virginia where many
years ago it compressed natural gas. Long abandoned, it was rusted
and broken but a dedicated crew gave it life again. Note that the
side shaft is both above center and on the “off” side of the engine.
It is throttle governed and uses the Watts pressure balanced exhaust
valve.
MILLER, 300 HP
This engine was bought new to power the Spring
Creek Air Plant near Kane, PA in 1911. It ran successfully
until it came to the museum in 1976. It was belted over the
flywheel to a large air compressor that pumped the oil wells. (See
next photo) It is the only four-cylinder “H” configuration known
with two cylinders forward and two aft.
INGERSOLL-RAND IMPERIAL TYPE TEN COMPRESSOR
This is the air compressor the 300 hp Miller drove. It has a 25 inch bore in the low pressure cylinder and a 15 inch bore in the high with a common 20 inch stroke. Using the air produced, Spring Creek could operate the old steam engine and the vertical lift “air heads” up to 11 miles away. What a piping system!
