Here's an accessory intake manifold that heats the gas vapor for cold morning starts.
I'll bet that add on was a big battey drain! There a lot of cast to heat up with the low engery batts of the time. I wonder how warm it made the intake.
Irving and Leonard Aske of Duluth, Minnesota filed and received some
15 patents for fuel vaporizing devices in the 1920 to 1931 time frame.
None of the three patents that I have linked to are an exact match for the
manifold in the photos, but each has some of the features involved.

Of interest is that the Lincoln's had a similar vapor pre-heating arangement on their intakes in the 20's. I remember seeing something about it in old Ford Bulletins.

They still make things like this. Zerostart makes them for big diesel trucks yet.
I agree, what a battery drain! I guess its just trying to heat the incoming air. Wouldn't want to get it too hot though.
Boy Jay, I sure enjoy these, thanks alot.
Art, your patent info always makes me smile.
Yep Jay, I think you need to get this stuff catalogued and put up a website and or make a book. It would a great reference tool and would most likely grow with other people sending their 'must have items'. It would be neat if someone found some accessory and could identify it and mabey get a reprinted copy of the instructions, or have a particular part in mind that they were looking for, but didn't know what it looked like exactly. Just a thought, Dave
My Ford diesel tractor has a preheater in the air intake pipe. It heats the air instead of having glow plugs in the head like the Kubota. There's no waiting like the glow plugs either. You climb aboard and turn the key. It fires up immediately.
