Here in eastern Pennsylvania, it has been a lovely spring, and
we are in the season of auctions and swap meets. At this time of
year, our readers move outside with their engines, and often we
notice a drop off in the number of letters we receive for this
column. So, we offer a few words of encouragement here, to send us
your letters and pictures, especially as you are out and about at
the many events that you find in our annual directory!

And now we move right on to our letters:

A frequent and welcome contributor, DR. ROBERT T. RHODE, 4745
Glenway Avenue, Cincinnati, Ohio 45238-4537 writes, ‘I enjoyed
reading Edwin Bredemeier’s letter in the March/April issue of
the Album. I’d like to add a few details to what he ably
presented. According to books published for those who ran farm
steam engines, there is an ideal placement of the threshing
machine. For the sake of an example, say that the grain is
delivered on the thresher’s right side and say that the feeder
end of the thresher is pointed west with the wind stacker toward
the east. It would be good, then, for the wind to move from
southwest to northeast. In fact, it would be even better if the
wind moved from west southwest to east northeast. When the
threshing machine and the wind are in such an arrangement, three
goals are accomplished: (1) the wind does not carry sparks from the
smokestack to the straw stack but delivers sparks off to one side
of the straw stack; (2) dust and chaff from the vicinity of the
thresher’s cylinder do not drift into the grain; and, (3) if
strong enough, the wind improves the draft through the fire in the
firebox.

‘Thresher men also must consider the wind’s effect on
the belt. When wind gusts are powerful, it’s best to cross the
belt in such a way that the wind strikes the slack portion of the
belt first, pushing that section against the taut portion of the
belt where the two sections cross. In this way, the slack section
will not blow sideways and cause the belt to begin to come off the
flywheel or the pulley. It’s true that the crossing of the belt
also permits a bit more of it to come into contact with the
flywheel and the pulley, thus helping to keep the belt in
place.

‘An agricultural engine is said to run ‘over’ when
the top of the flywheel runs away from the engine’s cylinder.
On most engines where the crankshaft is in front of an imaginary
vertical line drawn through the rear axle, the engine runs
‘over’ while the traction wheels are moving the steamer
forward. On most engines where the crankshaft is behind an
imaginary vertical line drawn through the rear axle, the engine
runs ‘over’ while the traction wheels are moving the
steamer in reverse. Engines are said to run ‘under’ when
the top of the flywheel runs toward the engine’s cylinder. Most
farm engines run ‘under’ when belted with a crossed belt to
a threshing machine. Running ‘under’ is said to be easier
on the crosshead and guides because the thrust on the crosshead is
downward and the guides are well supported underneath.

‘Thanks again to Ed!’
