Hi Gilda owners,

Does anyone have the (1938) Achille Gaggia patent application text, that goes with the numbered parts (1 - 37) side view picture of the Gilda? I can have it translated, if in the original Italian. I would to see how he originally described the operation of his machine. I'm into Gaggia history.

If anyone would know this, it's our baristorian, Sebastien, aka pootoogoo!

In search of Moriondo's espresso machine

The only other documentation I have seen is on Francesco Ceccarelli's site, here: ... 18965A.pdf

What I WOULD do for a good cup of coffee!

Hello Steve,

If you are really talking about the Gilda patent, you can check my episode dedicated to it (in French, sorry, it's still not translated) here: ... pisode-30/

... you will realize that it is not a 1938 patent. The real lever patent (from which the Gilda is derived) is rather from 1947. 1938 is the date for the "screw group" patent from Gaggia, that he bought from Cremonese (another episode in French, with the historical documents here): ... pisode-27/

The Gilda was out only 5 years later (in 1952). There is maybe an Italian patent, but good luck fighting with the Italian archives (and only if you are willing to pay for poor photocopies). :wink:
If you are just interested in the legend numbers and if you know bit of Spanish... here you go: ... 209_A1.pdf

You might look at the patents deposited in other countries too. They archives might be up online to different dates than our Italian one. The Italian patent office right now lets you search online only down to october 1989
In Spain it was Pat N. 204209 and Switzerland Pat N. 303990... the one drgary gave the link for is the patent for UK. I think I saw another couple around the internet but never really bothered saving them (sorry :roll: ) and right now I can find only those two.
As you can see listed even in the UK patent, the first patent date was 26 April 1952 which would be your reference for Italy.
And Gaggia, as company, passed so many hands in the last years that Im not sure how helpful they would be, at least through emails.
In any case all I ever seen about those patents doesnt have much more than what you see in the UK patent, like 3 sheets listed and nothing more. (I'm not even sure if there is a difference between documentation for the appication of a patent and the published documentation after the patent is granted, in all the patents I saw I havent always found a detailed description of every single part even if it was marked out in tech drawings)
