Default RIDER ERICSSON 6" - Brick - Cuir Piston Gasket

Hello to all.

Today my first hot-air engine arrived ... it's the right time, today in Italy there are 100 ° F.

I do not know these engines.

It's a nice engine:
- all original
- cast iron without breaks
- leverages without wear (worked very little).

Only the furnace grill is missing (not a problem) and refractory bricks.

Do refractory bricks be placed in the upper and lower section of the oven?
How to mount?
I've read that I have to leave a gap with the iron cast iron to prevent oxidation.
Does anyone know how to do?

I have to rebuild the leather piston seal, can someone tell me the outer diameter and the thickness?
Is leather first cooked in oil?

386/5000
Last two questions, my curiosity:
- the serial number is 15957, roughly corresponds to what year?
- the engine was redecorated (years ago) in light brown, but below I see a green paint, this looks original, is very old, there are no more layers.
There are also yellow / white decorations.
Could it be Green? Were not they just Red?

Regards
Davide

Bricks where placed in upper and lower furnace. There is a rectangular spacer that fits between the upper and lower layers of bricks to hold in place. I will try to post some picture of our 5" Ericsson.

Davide,
Congratulations on your fine engine. I am curious--how did it find its way to Italy?

I will try to answer your questions and I'm sure others will respond as well. Regarding dating, the serial no. indicates around 1906 although it is impossible to say exactly.

The refractory bricks were molded so they fit together like pieces of a puzzle inside the firebox. They fit in both upper and lower halves and are partly held in place by rectangular iron rings (these are often missing). But the engine will run fine without them, and if you want to insulate the firebox, just line it on the inside with thick refractory "wool" which is used by iron foundries.

You can buy ready-made leathers for your engine here in the U.S.; they are very nicely made by Don Worley in Pennsylvania. I can send you his email address. Or you can try to make your own using very soft leather. Leather is not cooked in oil, but softened with a leather treatment if needed. But if you make your own, they are first soaked in water before forming using the engine piston and cylinder. After letting it dry inside the cylinder it can be soaked in oil designed for treating and softening leather.

The yellow and white decorations are not original. Most engines were black with red flywheel but some green-painted engines are also known.
Brent

Hi Brian,
I imagine it is difficult to understand the structure from a photo.

A drawing, a sketch, might be sufficient.

Thanks for your help
Davide

Hi Brent,
Then .... I bought the engine in England, and there it came decades ago I do not know where.

Interestingly, your explanation about the leather seal, I'd like to try to rebuild it.
You have no indications on the diameter?
However, please give me the address of the supplier of leather seals.

Thank you

Davide

Davide,
The diameter of the leather should be same as the inside diameter of the cylinder plus a "lip" of about 12 mm on the sides. Thickness varies but maybe around 2-3 mm. I will send you by PM the email of the man who makes these.

Now more or less, I know what to do with refractory bricks.
No I'm passionate about this work: Headbang:, but it should be done!

Hi Brent,
thank you for your help.

I claim that I did not disassemble the piston, at the moment I have other restorations in progress, but I would like to try to rebuild the gasket.

You talk about 12 mm, but Diameter Piston + (12x2)?

Look at my drawing, right?

Davide,
Your drawing is correct piston + (12x2), although I've seen some a little larger or smaller. I sent you Don Worley's email also.
