The engine shown is a 1911 International Harvester gasoline engine. It
was most likely used to run a saw mill, but could have run a large
combine, thresher or large grain mill, as in grinding corn or wheat. The
flywheels are 60 inches in diameter and the piston is 9 inches in
diameter and has a stroke of 14 inches. That's 890 cubic inches, folks.
(single cylinder) And it is HAND cranked. I've done it myself. It is
not as hard as you might think, but you gotta get out of the way when it
finally hits and gets going. This bad boy weighs 6800 pounds. Eat your
heart out, Briggs and Stratton. No cheap die cast aluminum here. Good
old American cast iron. Notice the brass drip oiler on the cylinder and
the screen wire water cooler. This is called an evaporative cooler.
Water runs down the screen and some of it evaporates, thus removing heat
(cooling) the engine jacket water. Those old boys were not dumb!! What
a great hobby (and it is photogenic to boot)!!
All the pictures were taken inside a warehouse that has a few skylights and the camera was a Minolta 16 "QT" using the accessory flash unit it came with. Film was FUJI 100 speed Superia (home slit) developed at Wally-World 1 HR lab. The art girl at work scanned them for me.
