Recently I saw a new idea for a register tube, at least I haven't seen it before. I thought maybe others would be interested to know.
This is made by a German clarinet company which makes a German system clarinet and also have clarinets made for them by Schreiber. The Boehm system clarinet made by Schreiber had the register tube on the side, going in an upward diagonal through the body. Their main idea is that there isn't a tube inside the body at all. Also I think the angle and location help against water. I don't think the Schreiber clarinets have this type of register tube but I'm not sure.

Schreiber Boehm systems come in various different models, some of which have the "wrap around" register key. It is quite common for German system clarinets to have this register key design btw.

Yes I know some of the Schreiber clarinets have the "wrap-around" key, but I think they don't have this type of register tube?

The wraparound register key with no tube projecting into the bore was the standard setup on Albert system clarinets, typically placed on the top ie. 12 o'clock position. Rarely you'll find Alberts with a register key at the bottom as on the modern Boehm. Oehlers typically have a wraparound key that sits at about the 10 o'clock position. again usually no projection into the bore. Some Boehms made around 1890 - 1920ish have a wraparound key as on the Albert horns; I have such an example by Buffet. As to whether or not it is more successful than the bottom-mounted keys at keeping water out - I'd have to say I've never noted much difference between my Oehler, Albert and Boehms in this regard

Water getting into the register tube has nothing to do with the position of the tube. At that size, gravity is not a factor.
I had an old Buffet that had the tube in the front and it filled with water a lot- also, there was not much of the tube in the bore..

My Yamaha Oehler also gets condensation collecting in the speaker tube which is at around 10 o'clock when looking from the barrel end.
Similarly oboes and saxes also have trouble with condensation in the 8ve vents which are mounted on the topside of the bore - on oboes the 8ve well has a 2mm-2.5mm hole going into the bore (the 8ve top itself has around an 0.7-0.8mm hole depending on the make) and these get waterlogged in cold weather. I've played alto sax (an SA80II) outside in June and the upper 8ve vent was like a fountain everytime I went above upper A.

I have an old Pruefer [1910-20?] with the R T at about 9:00, with about 1/4 of its length outised of the body. It seems to be a good compromise between good 12ths and a fairly clean Bb. Newer [1950's] Leblancs and Selmers are similar in bore projection. I know of only a few patents re: R T design, and would suggest some searching if interested further. Don
Thanx, Mark, Don

Hmm... from the other posts it sounds like the register tube I described is not something new. But maybe I wasn't clear. Being on the side etc. is not really anything new. The thing is that the hole is at a sharp angle diagonal inside the body. It doesn't stick at all inside the body and sticks out very little, as a "mouthpiece" for the pad to close against rather than to add length. Does any other clarinet have that type of register hole (regardless of where it is)? From the other posts it sounds like people are familiar with this type of register hole.

Well... which company made it? Do you have a pictures or diagrams?
I think what you are describing is kind of like the way some bassoon and (sometimes) oboe holes are- ie. drilled at an angle with respect to the length of the bore.
Is that right? If that is the case, I have never seen anything like it on a clarinet.

Interesting concept - if a long register tube is a "must" (let's assume it is), then why have it perpendicularly through the wood instead of at an angle, similar to some of a bassoon's holes?
I do see the issue with waterlogging, though - for some reason the thumb hole and the register pipe are "raised" within the bore, probably to prevent water from being pushed out through them. Moving the hole's opening might be tempting, but we all know that water doesn't just flow riverbed-like near the (vertically) deepest path - else the "A" throat hole wouldn't be a very popular source of gurgling.

I guess I wasn't clear in my first post. Yes, that's exactly what I meant. A relatively sharp upward angle when the clarinet is standing (if I remember correct).

As I wrote it was made by Schrieber. I don't remember the company who Schreiber made this clarinet for but it was also German. I accidently lost the brochure I had which showed a diagram.

It's not a must for a register hole, but it can be because it acts as the Bb tone hole too.

Schreiber's description of the WS6025/6026 and the WS6045 Aura say that there are several slanted toneholes supposedly for improved sound and intonation. Looks like the side-mounted speaker key is one of them (with the claim of reduced condensation also). It isn't something I've come across before.

From the Schreiber website about the WS6025/6026 -
"Angled tone hole bores for C1/G2, E1/H2 and G1/ for a purer sound"
Interesting!

Interesting indeed because the opening of the tone hole along the length of the clarinet and also with respect to surrounding tone holes makes for a difficult intonation situation - hope that they have figured it out with this design? Also, standard undercutting of tone holes would be a reverse situation if the opening is not perpendicular to the bore hole?

I don't remember for sure but I think Schreiber's own clarinets i.e. those they make with their name on them, didn't have this type of register hole.
