Looking for an old U.K. Patent for Stirling engine

[JimPghPA]

Does anyone know of a site where one can access an old U.K. Patent.

The patent I want to look at is United Kingdom Patent no. 4081 by Reverend Dr. Robert Stirling for the economiser (regenerative heat exchanger) for his invention of the Stirling engine.

I have tried the U.K. Patent site with no success.

I contacted the main Carnegie Library in Oakland PA and after an hour an a half of trying they admit defeat on this one.


Thanks in advance.

I'd contact the UK office directly.

I sent them an e-mail a day ago. No return yet. I obtained a phone number today, and may call them.

It is amazing that such a popular patent is so hard to get a copy of.

They are 5 hours ahead of us now. They have not yet gone to day light savings time. When the do they will be 6 hours ahead of us.

The UK patent filing was not centralized in 1816. The patent was not called a "Stirling Engine".
Stirling patent was for "Economizer" filed at the Chancery in Edinburgh, Scotland.

"A" in the drawing is a chimney heat source as in B-1 of document:

Thank you.

I am aware of the drawing and the articles about how the Stirling works. I also am know about the patent being for an "economiser" and that essentially that was for the regenerative heat exchanger. From web sites about the Stirling engine it appears it was spelled with an s and not a z in the patent, but I am not sure of that.

What I am really looking for is an actual copy of the patent, especially the claims as I am working on a patent application that involves a heat exchanger.

I spoke with the UK Patent office today and they said that there online data base does not yet go back that far. They said I can order a copy for a nominal fee. However the section of their office to order it from was too backed up with calls to get through today. I tried to order an electronic copy via their web site, but there are some fields I do not have the required information for.

Thanks again.

Yeah, the patent was written in English, so it would undoubtedly have been with an "s"...recuperator was also common parlance in the day.

Funnily, with all of the Stirling stuff on line, I spend an hour yesterday and drew an absolute blank.

Would be surprised if this mob don't have it in their Paper Database, but don't see a login...
