6" Ericsson Hot Air Pumping Engine

this is the engine that was briefly advertised here a few weeks ago.
i disassembled and brought it home this past saturday with help from my son.
the owner bought an old house in Yarmouthport on Cape Cod a year ago and discovered the engine in the basement.
it shouldn't take much to get it running but it will may be a challenge to make it complete again.
these photos show some of the condition and i will describe in more detail in my next post.

Re: 6" Ericsson hot air pumping engine

Nice purchase. Any luck finding the water pump for it? Maybe in a shed or near a workbench? I was thinking it had to be on the property somewhere. I see the linkage and steering wheel of a centaur in pic 2. Is that at cape cod also?

Re: 6" Ericsson hot air pumping engine

the water pump was no where in sight but other than missing air chambers and petcocks every thing else was present and attached.
as i turned the flywheel compressed air escaped from the hole where the petcock belongs.
i may be able to save the leather piston ring as it looks in good shape.
the main beam photo shows an inventive blacksmith repair done with two slabs of hammer forged steel and several through pins, this will be left as is .
the heater jacket photo shows cracks which go all the way through so i will hand this to my welder.
an extra flywheel came along with.

firewood guy;
sharp eyes, yes that steering wheel is attached to a 1938 centaur G2 powered by a wisconsin THD ( would you like to see a photo of it ? )

Re: 6" Ericsson hot air pumping engine

Dan,
If you're going to the trouble to restore the engine, might as well get yourself a new leather--the old one is not likely to seal as well as a new one and so the engine won't run as well as it should. Don Worley makes high quality ones; he may also be able to help you with the cut off leg castings. The cracks in the hot cap no doubt led to its retirement from service. Hope you recorded the history of ownership of the engine. Thanks for posting.

good advise Brent, could you email or pm me with Dons contact info ?
i believe i talked with him a few years ago but no longer have his phone number.
there are two serial numbers for this engine,stamped on the bed-plate is
20518 and on the brass tag is 14744.
this engine either had a busy life a catastrophic event or both.
all the linkages on the engine are bronze but there are a couple of extra very rusty steel linkages and one half of a transfer piston-rod cross-head assembly.
these photos show condition of the fire box.

Re: 6" Ericsson hot air pumping engine

Hi Dan,
your bricks are very good.
Instead, I have to rebuild everything.
Can you tell me the thickness of the bricks?
Thank you
Davide

Re: 6" Ericsson hot air pumping engine

hello Davide :
sorry for the delay, the bricks are 1" thick.
decades ago i had my cookstove firebox relined .
i don't know exactly what was used but it was a cement product mixture that was formed in place.
it has held up through many cords of wood dropped into it.

Re: 6" Ericsson hot air pumping engine

Davide My suggestion would be to take the Brick out and Box it up in case you want to put in in a Museum and want it to be original all the way .... I would use A product called Fiber Frax and it comes in A blanket 1/2 inch thick . Just cut it to fit and glue it in with 3M adhesive . I have been running one like that for 25 years and no Problem . The first one I did was 40 years ago and I used castabale Refractory .It is still in use with no no problems . If the engine has not been run in many years the rust has built up behind Bricks and when you fire it the bricks will swell a little . It will cause the fire box to split down front by door or down one corner . any help Email me Buster

Hi Buster,
thanks for your advice, I also thought of making a refractory cement casting,
I think it's simpler than brick making.

But will I have to put a wire mesh inside?

I read that you are now advising to paste Fiber Frax sheets, I will try to look for it.

Thank you
Davide

Hi Buster,
another thing, I want to run the engine with wood, not with a gas burner.
So maybe it's better the refractory cement casting? Respecting Fiberfrax?

Thank you
Davide

Hi Buster,
the Fiber Fax, is a roll product similar to the picture, or is a slab?

Thank you

Davide

Re: 6" Ericsson hot air pumping engine

We used the fiberfrax on several hot air engine fire boxes at our museum and it works great. We fire with propane but I think you will be fine using wood.

It was a used 1" thick roll that came off of a large muffler on a generator in a building.

Re: 6" Ericsson hot air pumping engine

Davide The Fiber Frax I used was in A roll like in the picture What I used was 1/2 inch thick and no problems ...When these engines were used for Large amounts of water the hot cylinder was hot enough to turn Red . When running at show they never get very hot and 1/2 inch is fine . just cut to fit and use 3M contact cement to glue it in Works good Buster

Thank you all for the information.

Buster, talking 3M adhesive for me is too general, you can send me a link?

Thank you

Another brand of this insulating material is "Kaowool" which I have used. I'm unsure of the effects of ceramic fibers on the lungs, so I use a respirator when handling this stuff.

I think that Kaowool may be same material The Fiber Frax I used I got from southern California May have the box and can get address I used 1/2 inch thick and worked good .It comes in A roll and can be cut with A small pair of shears The Glue to hold it in is 3M Super 77 part number 76098 I got it from wall mart or any of parts houses Hope this helps Buster

Thanks Buster, thanks Brent,
I purchased a fiber similar to FIBERFRAX, used to isolate the furnaces.
I did a test with a very powerful gas burner (I use it for starting hot bulb engine), the result was great, it did not get any damage, and definitely the firewood will have a less hot flame.

Then I bought a Spray Glue (hopefully similar to 3M super77) and finally I bought refractory bricks, I will put them only at the bottom of the furnace where there is wood.

Next week I hope I can post some photos.
