The notched wheel at the outboard end looks like it might be
a row of magnets for some type of generator, but it doesn't
make sense to power a generator with a single-cylinder steam
piston... unless these things are pre-1915 which they don't
look.

It makes sense when you already have the steam available, and the
cost of electric is high. The one in place powers part of a
mental health care facility. With both engines up and running,
they will power the whole place.
they already had 2 big coal fired boilers and I brought them an
oil fired boiler last year.
Most of the engines are from the 30s - 40s. The oldest I've
transferred was a 1912. Lots of exposed , whirling parts.
Most of the engines are running wood mills where they burn the
free sawdust in the boiler.

Amen!


The flywheel is the giant ring with square holes (it is painted). teh
square holes are for the guys like me to lock a jack in so the engine
can be turned slowly and controlably for any of a number of maintenance
procedures.

Per a resounse above - the unpainted thing is a ring of field poles. It
is called a salient pole mancine as opposed to round rotor. You could
could them and devide by 3600 to figure out what speed it ran (sllooww).

The crank / flywheel / rotor assy. Weighs 9 ton.

This is the sister engine, one serial # apart. We set this one up
about 10 years ago.
It's very dark in the powerhouse, so most pics came out too dark.

Thanks Scott. I haven't seen any like that, looks like the slide valve is
built into the bearing housing. What's all that stuff in the middle of the
flywheel do?

Sure looks heavy!

Matt, thanks for the explanation. This machinery is a bit
outside my experience and I appreciate the chance to learn a
little about it. Is there a particular type of plant that
uses these generators?

You've done that too, eh? I was amazed at how easy they turn the
first time I tried it.

Nope. that's the flywheel. See all those square indents around
the outside, middle? that's to hand crank the engine. Put a big
bar in those holes.

I don't think is is a multi flow because all that I even ran had a big
exhaust chest in the center of the cylinder.

Yes, that is the rotor and field of a large low speed generator.

Oops, I think maybe it's a Uni-flow. Big difference, huh?

I tried, but the room was dark and there's a big window in back
of the engine, so the pics didn't take.
here's the other side of the cylinder.

Thanks for the further pics. I'm guessing the red valve is
the exhaust. The valve operator gear looks simple.

Maybe I should look on E-Bay and see if I can pick up one of
these things... cool toy!

DSK

Doug,

I'd say the "Red Hand Valve" was the inlet Valve. The two reducing
valves are on the exhaust side. Just an idle observation of and "Old
Huff & Puffer"
