BeaverBoy:
A relative newcomer to the forum, my introduction post said that I would put up some pics of this engine - inherited from my late uncle. I have little idea about it, so can someone help?
Some idea of what the brass attachments are for would be a start - some kind of pump?
Also, there is quite a bit of free play when the crank is at both bottom and top dead centre - obvious when you see how the big end connects to the crankpin.
All comments will be greatly appreciated. Hopefully the pics will appear - or will they? YES! they did.

Stuart:
Looks like a rotary boiler feed pump with a type of scotch yoke crank

But I could be wrong

Roger B:
I agree with Stuart that it is a pumping engine with a scotch yoke crank. As the power is transferred from the steam cylinder to the pumping cylinder directly and the crankshaft and flywheel keep it going past the dead centers it might be quite an efficient setup  :headscratch:

BeaverBoy:
Thanks for the answers so far - the fog is beginning to lift a little!

Do those big rods at the sides on the bottom pivot? Not sure what those are, unless they are shutoff valves? Don't look like they are pipes...
