Identifying Old Stationary Engine

Morning,

First post here so treat me gently! Looking for some help identifying this barn find down in Kent. The BiL's find actually, he's just a Ludite when it comes to forums. No brass plates or casting marks found so far. Not even sure on the fuel type but guessing 2-stroke? Cheers.

OK, I'm guessing 4-stroke, as it has a cam operated rocker to what appears to be an exhaust valve. Any evidence of an inlet valve ??

A quick skim through the A-Z, suggests two possibilities, in no particular order:

Rogers and Kaye gas engine made in Bradford, from about 1897.
H.W. Davey gas engine made in Lincoln around 1905-1920.

Both engine have the disctinctive long-nosed base, the crankcase with an edge rim, bearing caps facing outwards, cylinder attachement with 4 bolts, and sideshaft on the wrong side of the engine.  The engine has also been modified from the original hot tube ignition by adding a spark plug and magneto. The sideshaft may also have been modified at this time.

The flywheel with the S shaped spokes was used by Davey, but not by Rogers and Kaye, so that might be a pointer to the identity. The Davey should have 2 flywheels, so maybe one was lost.

I can't confirm the identity 100%. The only thing which bothers me for either attribution is that this engine does not appear to have a detatchable cylinder head.

In any case your BiL has found an unusual and quite possibly valuable engine.

Thanks for that. Stripped down and the head is btw removeable. The piston was well stuck in but now out. Con rod is slightly bent. Repairable? Had a suggestion it might be Stuart Turner?

Looking like its from the National Gas Engine Co. Now to find the model and maybe a manual!

Looking in my copy of Stationary Engines for the Enthusiast I tempted to agree, but the flywheel spokes look a bit odd (maybe swapped) and the illustrations show 'National' on the cylinder. I bow to others with more experience.


Edit,

Having leafed a little further to the section Small-Power Engines there are a number of similar looking engines.
Will stop digging now.

Just ordered a copy of Stationary Engines for the Enthusiast thanks!

National Gas Engine Co never built an engine with a rear sideshaft as far as I know, so I don't know who told you that.
Also not a Stuart Turner engine.

Have a look at these pictures (copyright A-Z).

I'm reasonably certain that is is a HW Davey gas engine.

I'm thinking that it is not a Rogers and Kaye engine, but that HW Davey may have copied this engine for the production of his own.

Hi did you ever restore  the engine you found .it was a H W Davey
