Paul Isaacs Jr. Donated this Yeager Cement mixer with 3 Hp Fairbanks Morse Plug Oscillator.
The engine does not have a spark plug but makes a spark from a set of contacts inside the cylinder right as the magneto fires. This was state of the are cement mixer in its day. The engine turns several gears and the drum. There is a clutch that can be engaged to lift the bucket with material into the drum. Water is added from the tank on top of the machine. Once mixed, it could be poured out of the drum.
