Mystery steam engine

[chris123]

Sorry I didnt got it 3x
Anyway
I shot better pics from the inside before i start so u can see again
If ok i start measure

see in the small one are hohles
The big triangle is round inside
Tegards chris

More pics

can you take a piece of wire and see if the openings at the ends of the round HP valve chest (1) are linked to the ones at the ends of the LP chest. (2)

If they are linked then that is how the exhaust steam from the HP cylinder gets to the LP chest via cored in passages around the side of the LP chest. It's a bit of a long route but would have acted as a bit of a reciever.

I also wonder if the two valve rods are original as they are just plain rods so no means to adjust the valves by nuts. Maybe a previous owner started working on the engihe and only got so far. Or did someone take it apart and start restoring it, making new valve rods but did not finish them.

Hi jason it is
Im happy to measure it
As green twin mentioned with the d valve
Bud there must be soemthing else in the small hohle
I dont think alan got more parts
He used it as doorstopper…
Welll
Regards chris

l also forgot to show this lever properly
Its more a bracket or a guide for a rod

Most of those shots with the wire are as I would have expected. It is what links the round piston valve chamber to the slide valve chamber that would be good to know. You might have to poke it in from either end and just get an idea of where it is going as the wire may not bend all the way round. Then measurements can be taken to sort out what needs to be made.

I thought perhaps the end covers could form the passage between the Piston valve and the slide valve? But not seen any evidence either way.

From the images in the first post there is not much thickness (maybe 1/8") to the end cover so unlikely and would still leave the question of what the slots are for.

Ok thank you jason
I will do that

Ok thank you jason

Start tomorrow with the wire and send pic
After start with the measuring instructions
Of green twin
Best regards chris

Hi jason
On the side i cant get through from the little round one to the triangular slider
Only on tpo and bottom is a slot bud big
I try again if i get through somwhere on the side
Otherwise only top and bottom from this round part in the slider hohle
Regards chris

One guess is that the piston valve has inside admission, and outside exhaust, and so when the piston valve goes down, the exhaust goes straight over into the rectangular steam chest.
Not sure about the event timing.
The rectangular steam chest is pretty generously sized, and so perhaps acts as a receiver.

Hi green twin
I blew smoke inside the round hohle on top
It also came out on front where is no copperpipe

Hi jason and green twin
Its hard to picture

Hi jason and green twin
Its hard to picture

I also blew smoke into copper pipe
Came out in slider area
Blowing into little hohle comes out on other side with no copperpipe

This is a typical single-cylinder non-compound passage arrangement.
The exhaust is connected to the center passage in the port face.
The first image only shows one passage to one end of the cylinder, but there are passages to both ends of the cylinder.
Exhaust is the blue passage.
This should be how your low pressure passages are arranged.

What I am not clear about is the connection(s) between the rectangular low pressure steam chest and the piston (high pressure) valve.
