I have a Leblanc Eb clarinet. It is marked with a silver marker with the text Werschnik patent. It is a special version where the clarinet seem to have been drilled out with a different profile inside. I am trying to tune the clarinet and have difficulties with the high c (i e the c with only left thumb and octave key). This is much too high in tuning. Even when I try to compensate for this by lowering the ring mechanism with a thin slice of cork I do not get enough effect. Lower registers are rather ok or at least more ok than the higher registers in tuning.
Does anyone know anything about Werschnik and his patent. And does anyone have any tips for tuning the clarinet.

Perhaps the register key is opening too far.

Lars - Many thanx for posting this question, I have had a copy of Alois Werschnik's earliest US patent, its on upper joint bore configuration, for some time and have wondered about its being used by a maker, now! LeBlanc. I have copied off the related patent art, and will look them over and comment, BUT now we have a TStorm moving in [ NE OK] and I need to get off so as to not lose another modem to a lightning flash. Don
Thanx, Mark, Don

Don!
Alois Werschnik! Interesting. I wonder what he had in mind? I have tried to adjust the different ring keys and what I hear and see at the tuning machine the upper rings should be almost 100% closed. On the other hand this affects the functioning of other parts of the clarinet. The high c tunes ok but then the b is too low! Maybe I have to think a bit more about the possibilities of the mechanics of the keys?
It is also interesting that the lower registers seem to be rather ok tuningwize, but at the same time the upper registers gets off tune.
I have also thought that the clarinet needs a bigger mouthpiece. I have tried pulling out, but still the tuning problems are there.
I will be very interesting to see what Alois did try to achieve! Do you have a date when he lived? There are many questions.
The plaque in silver is very neat and screwed to the clarinet, partly over the brand name Leblanc. From what I see no major changes in the mechanics is made. It is rather mysterious that there is a hole in the bell. I have used a piece of tape on the inside of the bell to see what effect the hole has. Some, but not much! What was the purpose!
Thanks!

Sorry!
There seems to be some problem with the word file. My computer tells me it finds "malicious scrips" in the file. Nothing really bad happends and I can open the file and see the picture. But to be on the safe side, maybe you should not open the file!

It's fine. I checked it out and there's nothing that will harm your computer

Hi Lars- Do I read the se as Sweden? Welcome, no matter wherefrom. You can read and copy-off the pat info that I have, by accessing the US Patent Office site by a Google search for USPTO, go to the Databases, Issued, Quick Search, use Werschnik AND clarinet. Will give 3 pats, the 2 by W and a citation [as prior art] in a cl barrel pat to Smith, also interesting for cited patent info. etc. This will keep you busy for quite a while!. I think this might be W's [Munich, DE] answer to Carree's Fr-Buffet pat & development, of the mid '50's "modified cl bores" for ?better 12ths?. It may be that this German ?improvement? doesnt work well on a FR-US Eb clarinet and you have an "experimental model"! Perhaps the museums in Munich and the Bate in Oxford would like your cl!! I hope that Al Rice, cl expert, may read this and comment! When I have an hour or so, to study the pats and look in some of our "good books" I'll prob. comment further. Luck, Don
Thanx, Mark, Don

Thank you very much for your suggestions. I will check the patent office. Looking forward to further comments if and when you have time.
Yours,

I have studied the patent applications of Alois. They include a lot of detailed discussions that is hard to follow.
A thing I do not understand is how some of the upper note pitches can become too high? When at the same time the clarinet is a rather standard Leblanc clarinet that is adjusted by enlarging the bore in the upper segment of the clarinet? To me logically the pitches should become too low if anything.
