This looks like a Davis engine that was made in Waterloo Iowa.

It is mentioned in the book "Engines of Iowa"It was used in industrial applications and also in some 1906-1914 cars such as the "Economy Motor Buggy" and the "Success" from St.Louis.

I have some pictures of an Davis engine from Brady Mann Peoria Illinois ,who restored a 1909

Economy built in the building that I own in Joliet Illinois.

The engines are not identical but close.

The flywheel with the cooling fan built in is the same and the general layout.

I can email you some of these if you give me your Email address.

I do not know how to attach the to this post.

After a bit of research, it may be a variation of the Maytag Twin-Cylinder Multi-Motor with a missing pedal kick start, but it looks way to large for that.

The keyed output shaft doesn't look very automotive to me, maybe marine?

Doubtful if it's either automotive or marine. More like industrial stationary.

It just hit me we can see spark plugs but nothing going to them. Wonder if there should be a magneto on that shaft with the large wheel on the other side intended to handle a belt. The carburetor on that thing looks much like something one would expect to find on a Briggs-Stratton engine.

Yes it has a Model T carb..Don't think that original... look above the crank shaft there is a timmer...so it was a Batt. and coil ignition...the reason I don't think its a stationary is there is no governor or a place for one...

two valves per cylinder...the intake valves are atmospheric, but in the same chamber as the exh.

yes, the vacuum created by the down stroke of the piston overcomes the small spring holding the intake valve closed. and when the power stroke of combustion happens, the valve is kept closed because of no vacuum then. charles coker, 1953 pontiac tech advisor.

Nah, ya can see the two little spark plug pegs on the timer. It looks a little like a Model T timer but with only two plug nubs. I know what you mean about it looking like an air compressor, though.

Here's a few more photos..The Flywheel is 17"...I can tell you it was never a air compressor.....Thanks for all who have responded...I'm sure we all would like to know what it came from...Ed

Take your word for that, HartParr, but the possiblilty of such an arrangement is real. I have

a tire filling apparatus for a model A Ford which simply screws in a sparkplug hole. It seems

the atmospheric valves would be ideal for such an application. Interesting Post for sure, but I notice it still is not well settled, as many say 1910ish, and others see the technology as closer to 1920s. Could have powered a plethora of industrial devices.

Schucks, more questions! Would this not have been one loud mother with no muffler?

Also, what is the stem for in the middle of the carb? I am not familiar with model T carbs, but

did not know they had that? Bhigdogs right...you should put a couple spark plugs on it and get it running! Wear earplugs, though!

The "stem" is to adjust the main jet. There was a rod that went through the dash on a "T" so you could adjust on the fly.

The carb feeds both cylinders and both cylinders have spark plugs. As already noted, it has a timer with two terminals. The exhaust joins together into one outlet. Ergo, it is not, nor was it ever, a compressor. It is a gasoline engine. Could have come from a Henway or a Rolls Kennardly for all else that I know;-)

Similar to the IHC air Cooled Highwheeler design. I know it is not from an IHC Highwheeler, but I would say it was in a similar type vehicle or light truck. I also agree it is not a stationary engine. Dandy Dave!

It looks to me like an early railroad inspection car engine. Air cooled 2 cylinder. Very utilitarian. Maybe post pictures to the NARCOA website??
