Mystery steam engine

[GreenTwin]

I can't find any compound model marine engines that look like your engine, so I have to guess it was not not a popular design like a Stuart, at least not popular in these parts; perhaps popular on your side of the world.
The key would be to find some member here who says "I have one of those, along with the plans", but nobody is speaking up so far.

Here are some Stephenson's Link drawings, with labels that may or may not be applicable to the parts on your engine.
Gives an idea of what is happening with the mechanisms when the level or wheel controlling the link position is moved, ie: sliding the link forward or back in the case of your engine.

I thought there would be drawings around
To which this engine is made thats what i meant
So i could see how and what bud
As i said before it just came out of the diesel
And i took only the alu clad off and the timber
Because soaked in diesel
And opend the cylinders up so they clean up
Thats all i did
It is pretty stiff to move

Regards chris

I am forgetting all my steam engine valvegear names.
I will try to find a good example with the correct labels.

This engine appears to be similar, but not exactly the same as yours.
.

Dont worry man
I dont know nothing
I getting a little idea how that might works
Thank you
Chris

Yes i found this also thats why i mentioned it
And i couldent find anything like that on it
However
Im in sydney and alan (my mate who gave it to me ) lives in nsw also

I think it will be easy to get your engine running, if you proceed with caution.
I am posting a lot of general information just to be informative about compound marine steam engines with that valvegear type.
Somewhere in one of these drawings is probably the exact connecting arm that you need.

Thank you very much for your time
Im absolultey stunned
Thanks heeps

These two look similar with the wheel that actuates the valve gear horizontal rod via an arm.
One has a gear.

Now that would make sense how that wheel would work

If your two rods rotate only, and there is not a long threaded part on the wheel shaft, then you probably have a worm gear configuration, like these engines.

[chris123]

There the half gear and screw go

Bud it sort of not work with
The other connection
You know what i mean?

 

[GreenTwin]

I suspect it should be similar to this.

Yes exactly i just thought where the radial slider goes

Well its 11. Here
I gonna go to bed
Thank you very much
And high apriciated

There are bosses on both sides of the links, so perhaps a forked lifting rod ?
We can continue tomorrow.
Hopefully we will get more eyes on this in the coming days, and get a 2nd opinion.

Yes very smart idea
Good morning by the way

I am looking at the relative positions of reversing handwheel shaft that runs across on end of the engine and the weighshaft that runs down the side and moves the reversing gear. If there was a lever on the end of the weighshaft then I would expect the revesing shaft to have been threaded. As it is not, I think perhaps it should have a worm and sector arrangement.

It also seems to be missing the 'lifting links' from the weighshaft to the pins on the ends of the curved 'expansion links'.
