Sadly some text pages are missing.

Luckily, all schematics are available

Please double click on the front cover as to open it in PDF

 

Let us consider the so-called Anlagen or schematic section, some of which showing the schematic interactions for the various operational mode options

Please remember, that the schematic pages below (Anlage 1 - 11 = Attachment) are also available in PDF in an A3 format; Abode has a printing option which says 'print what you see'. Thus, when the schematic is fully visible on your screen, print it this way and you will get it printed in an A4 format fully!

Some new G-Schreiber schematics and other things being added today.

 

 

 

The Siemens Geheimschreiber concept is based on patents which were applied for in the very early 1930s; most likely, that Siemens might have started working on it in the late 1920s.   

 

Anordnung zur Nachrichtenübermittlung in Geheimschrift über Telegraphenanlagen, date of application 18 July 1930

Extended by:

 

Not yet two months later Eberhard Roßberg on behalf of Siemens & Halske applied for an invention extension, claiming improvements to the original patent (Zusatz zum Patent 615016)* 

* They likely might have encountered obstructions, or, they took their time as the basic invention claims was being covered sufficiently; it was ultimately granted on 29 September 1938! Whereas the original claim was been granted on 29 May 1935.

By the way, in the 1930s Siemens filed the most German patent applications!

In those days the bureaucratic granting process took often quite long. Don't wonder, when a patent was applied for in, say, 1934 and that it was finally granted in the course of the 1950s!    However, a successful patent claim starts legally from the moment onwards when it is handed in; which is noticed in hours and minutes of an application. Sometimes a special courier handed an application in at the patent-office; even up to the bitter end in April 1945! 

The German Patent legislation changed in 1937. Its objective was, among other things, also focussing on the fact that 'blocking' your competitors was rejected when the interest of the Nation (Reich) was at stake. ('Lizenzbereitschaft' forced on behalf of the Reich)

Please consider also:

Das neue Patentgesetz 1936

and

Werner von Siemens und das deutsche Patentwesen

and

VO vom 15.1.44    For its PDF format: Verordnung zur Einschränkung von Veröffentlichungen im Patentwesen

As to get an understanding as to how the Germans handled their patent applications bureaucratically, it is interesting to take notice of the example: DE762245

The existence of these kinds of documents was incidentally discovered by me in early 2006. In those days I did my patent search in the Patent section of the British Library (Intellectual Properties), which I did for more than a decade. In London they were astonished by my findings, which truly was more a matter persistence and having a 'good deal of luck'. These kinds of papers you will hardly find elsewhere (outside the German Patent Office)*. After a patent has been granted the only accessible file possible is the official legal patent paper. In my patent dbase these sorts of files are being marked by means of an extension 'ap'; however, don't add or use it when you enter a patent number on the web or elsewhere!

* The problem is, that these patent are not classified, and likely will never become. How I accessed them? The British and US Government ordered the German Patent Office to make abridgements of all German patent applications between the end of the 1920s up to 1945. The so-called Patent Auszüge were published about the end of 1948. Copies of these 'blue volumes' are available at the British Patent Office. It was, by the way, Tom Going who brought these intriguing volumes to my attention in September 1995. However, say 10 - 20% of them carried also the later legal patent numbers; I wondered why most of these got at the microfilms the message: This Patent is not Available. Staff of the Patent Office told me, that this was due to wartime bombardments. I wondered for a while, how intelligent the Allied bombs must have been that they only destroyed the interesting files!
