We now have a list of 23 Comfortractors, none listed in
Canada-we think there are surely some there.
Maybe I ramble on too much, but we even got a letter from a
fellow telling us he had seen a tractor like we advertised for in
Illinois-which we purchased last winter.
In the 35 years we have been married, I don't know if I ever
wrote a letter, but now I have written up to five letters a day
answering people. We think it is very exciting corresponding with
people from all over the country.' (That's part of the
hobby fun, LeRoy, hope you continue many years with it.)
ED F. EDWARDS, P.O. Box 197, Big Bend, California 96011 has sent
us a write-up on his engine and two pictures: 'I recently
acquired this engine and I would like to find out what it is, what
company manufactured it and about what year?
There are no casting numbers on any part of the engine and no
apparent place for a nameplate to go. There are several very odd
things about this engine. The cylinder from the head half way back
is tank-cooled; that is to say a water jacket is cast around the
cylinder, where as the other half of the cylinder is air-cooled
with rather wide, rounded fins that are spaced far apart. The
piston connecting rod is round. The intake valve is inside a
bell-shaped casting, which a 1?' pipe screws into which the
carburetor is down at the end of, so that the gas and air mixture
is drawn up the 1?' pipe and (around) the intake valve (stem
and spring) and into the cylinder. The bell-shaped casting also
serves as a folcrum or pivot point for the exhaust rocker arm.
There is a babbitted, cast iron guide which is bolted to the side
of the cylinder head which supports and guides the exhaust pushrod.
There is a single governor weight in the flywheel which operates
the hit and miss governor.
The flywheels measure 29?' x 3' and it has a 6' bore
and 10' stroke.
Perhaps the oddest feature of this engine is that both of the
main bearing caps are bolted on at approximately a 45° angle away
from the cylinder instead of directly on top or at an angle toward
the cylinder as on all other old engines. Both main bearing caps
are broken, but I have all the pieces.
I hope to hear from some of the experts out there. Maybe the
identity of this engine will prove to be somewhat of a challenge. I
will answer all correspondence.
'I have just acquired a 6 HP open crank Dempster engine,
shop #15711, class 6H. There are many parts missing and I would
like to correspond with anyone having a similar engine. So I can
find out what parts I need.
If you feel you can help this man with his Dempster engine
please write ED PROSS, 931 Delphi, Lafayette, Colorado 80026. (Ed
would also like to see an article on pouring babbitt bearings. And
so would we-anyone out there have the time and ambition to send one
into us would be appreciated.) Babbitt Connecting Rod Bearings.
