Nothing Special Posted July 26 Share Posted July 26 .... Somebody knows the goal of that spinning device (shaped as a modern anemometer) just behind the chimney?... EDIT: Just an idea... Is it kind of "spring loaded" and it "flattens" as the engine speed increases, kind of visual RPM?... Just a guess, but if it's spring loaded and flattens as engine speed increases I'd guess it's a governor, that opens a valve to release pressure as speed increases. but that's just a guess.

It's called a flyball governor and throttles steam to the cylinder. When running, the lift of the spinning balls will lessen the orifice that steam has to pass into the engine. This is where we get the term "balls to the wall" when flat out. It's also why The Hartford Steam Boiler corporation became The Hartford Insurance corporation. All along the rivers in Connecticut water power gave way to steam I'm the mills and factories. Unscrupulous owners or foremen would lash the balls down to make machinery run faster. But this increased pressure and steam boilers would regularly explode with catastrophic results to life and property. The boiler company had to protect itself from legal actions, this Hartford became the Defacto seat of the insurance industry in the US. Link to comment Share on other sites More sharing options...

The 50 Chevy pickup we have has one in the intake under the carb. The pic on the left shows the inner workings of it, although I don't know how it worked. And the one on the right shows the plate in the intake that the governor closes or opens. Link to comment Share on other sites More sharing options...

This is where we get the term "balls to the wall" when flat out.... I've also heard that "balls to the wall" came from aircraft, circa WWII. In cars we talk about "flooring it" meaning push the throttle pedal to the floor. In aircraft the throttle is a lever that you push forward to open it up. All the way forward would be to the firewall. I've heard the term "firewall it" meaning open the throttle all the way comes from this. And since there was typically a ball-shaped handle on top of the lever, and there'd be multiple levers (and therefore multiple balls) if there were multiple engines, "balls to the wall" was also said to come from that. But that's just what I've heard, I have no way to verify it. Link to comment Share on other sites More sharing options...

BigBrother-84 Posted July 26 Share Posted July 26 Pardon me, the term is "balls out' https://en.m.wikipedia.org/wiki/Centrifugal_governor Aaaahhh... thanks Gentlemen, for this educational pause. I love it, and like the feeling of being a little smarter at the end of the day. Not to mention I'm a bit proud to have noticed that these spinning balls seemed to go up an down in the YouTube video. Centrifugal Governor, yeah, nice engineering. Link to comment Share on other sites More sharing options...

Gary. it's a velocity governor, note the off center throttle plate. When the airflow reaches the set value, it closes most of the airflow off. It has the wrong gasket on top of it, the correct gasket has a hole that allows the power enrichment vacuum source to come from under the governor, otherwise it would run dead rich when the governor came in.

Good to know, Bill. We aren't using any of that as the 235 comes as a complete unit, inc carb, starter, and generator. Link to comment Share on other sites More sharing options...

HEART ATTACK! 💔 I'am preparing to reinstall the C610 connector, and beginning to examine the various wires there... During a second or two, my heart ceased to beat: The exhaust manifold was splitting!!! «Ok Jeff, don't panic, take a closer look and see what's going on. Why didn't you hear Big Bro raging as a sports car ?!?» I told to myself. Hahahaha! I'm stupid! This is just the heatsink! ❤️🩹 Link to comment Share on other sites More sharing options...
