Men at Work - WBD Bischoff Hot air motor
« on: March 21, 2021, 08:05:58 am »
Inspired by Nick I had to run my very old Hot air motor
made bei Wilhelm Bischoff of Dresden maybe 100 Years ago.
It is quite loud but powerful and those workers had to speed up.
The "Arnold" group of workers usually moves by a hand crank.
Enjoy, Arnold ;D

Wow! A beautiful and large hot air engine. Maybe a bit more power than needed for that job, but great video of 2 rare pieces in operation.

I am surprised that the workers are not afraid in the face of the machine. ;D

Arnold,
Thank you for this.

I have a friend who has this engine, and as far as I know he was never able to identify it by manufacture.  I will have to let him know it is a Bischoff.

That is indeed a very nice hot air engine. I was wondering how did you identify it as W. Bischoff? I have never seen it in their catalogs. Thank you for the video. The photo of the second engine appears to have a different maker's plate.

This is exactly the same engine - and it has a name plate that read
Sev. Krieg, Zurich - that is very interesting cause the seller told
me then it was made by Wilh.Bischoff Dresden. Now I believe it could be
Swiss made - who knows more? Could you please ask your friend to let me
have a picture of the name plate - mine is gone - there are only 2 small
holes from the nails. All I have is the serial number 108!
Thanks Arnold

I also asked myself - because I have the old WBD catalogs. The seller probably told me a fairy tale
- it seems to have been made in Switzerland - that would be great. It is very
precisely made and the frame is all made of brass.
Thanks Arnold

Here is a Photo of the name plate on my Friends engine.

I think we had figured out that is a educational supply house that sold mechanisms to schools?

Thank you - I am agree - for physics lessons in high school
it was never a toy. So it's probably not that old - more in the range of
1950. I think I'll have a manufacturer's plate engraved on me.
Thank you for your kind help, Arnold :D

Arnold,
I looked through all of the other pictures I have of this, and found this plate on top of the engine.

[ Guests cannot view attachments ]

Type 2 Nr. 111

So If yours is Number 108 and this one is Number 111  then at least 2 are accounted for.  I do have pictures of another one.  I will have to zoom in and see if I can read the plate on it.

Thank you Jim for your detective work ;D
