Reversing Mechanism - Meccano Steam Engine

John · Reversing Mechanism - Meccano Steam Engine

Can anyone provide a photograph, sketch or description of the reversing mechanism on the original Meccano steam engine?

Thanks

Hi John,

If you look on Wallace's website and scoll to the bottom you can see a photo of the mechanisim detatched from a Meccano engine.
Not sure it will provide you with enough detail but it's a start.

Welcome its always good to get another local Perth member.

I can take pics of mine if that didn't help. What is it you want to see?

John

Thanks Tony, Wallace's website images give me a few clues to work with.

Thanks for your offer Nick.
I have built a small 'wobbler' type steam engine that I can 'build in' to Meccano models-as shown below. ( Sorry about the focus) I thought it would be nice to be able to reverse the engine by changing over the steam flow as in the original Meccano engine rather than having to build a gearbox.

Rather than re-invent the wheel I thought I would find out how Meccano did it.

Thanks

John

Hi John

Nice engine

I could get some more pics of the reverse mechanism if you would like. I haven't taken much notice of it on the 1929 Mec engine, but assume it would be much the same as a Mamod.

Ahh John what you want is pictures of an se2a reversing mechanism or a Roadster or any other Mamods that use a similar method.
Has anyone got a good photo of that to put up?

John

Thanks guys.

A drawing or photograph of the operation of the reversing valve from any or all of these engines would be would be great.

I am looking for some thing that is easy to make and compact. From Wallace's images it looks like a rotary valve is used to direct the steam to the proper port to make the engine run forwards or backwards.

Will grab pics or sort something tomorrow for you hopefully
