 Offset / asymmetric / ergonomic register keys
Author: rsholmes

A couple of recent threads have dealt with offset, asymmetric, "ergonomic" register keys -- on the Marigaux:

and on the Ridenour Lyrique and TR147:

Here's a photo of the Marigaux key:

A similar key on a Hanson:

I'm curious, have other clarinet makers used a similar design? Does anyone hold a patent on it?

The Buffet Tosca has, as does the Forte clarinet, and I think Ripamonti clarinets have an assymetric speaker key.

The opinions I express are my own.

The Forte clarinet has an ergonomic sculpted register key:

The Rossi has had one as long as there have been Rossis.

It was also on a Leblanc Robert Lowery(sp) model, a fine instrument.

I saw an asymmetric key the other night -- I went to an enjoyable concert by a local clarinet quartet, Highland Winds, and there was an asymmetric register key on the bass clarinet. I forgot to ask him afterwards what make and model it was.

I believe Lowry[sp?] has an older patent on his R K which was available on Leblancs in the ?50s-80's?, may still be obtainable? I'll make a pat search tomorrow, if no one "gets there first". I have seen only a few modifications beside the old wrap-arounds and the doubled touches ETC for the larger cls, with worse R K PLUS Bb problems than the sops have. The fine paper given by Debbi Reeves at the Edinburgh meeting, when available, devoted to the Bb/Register Vent [compromise] solutions, might show other designs also. Don

Thanx, Mark, Don

I have been unsuccesful, RSH, in looking up a Low[e]ry register key touch-shape pat, it may have been un-patented, or via a "design" pat, non-retrievable somehow. If you wish to view some of the many register key modifications "proposed", but only a few actually produced, Search on Google/Patents via "clarinet register key", it is a bit more convenient than retrieving by a USPTO search. Will lok for my Leblanc ad for the "Lowry" key. Luck, Don

Thanx, Mark, Don
