The "François Louis" mechanism

This new revolutionary mechanism is an enourmous step forward in woodwind instrument conception. The results are: reduced weight, reduced friction, increased response, and increased strength. It makes it possible for the repairman to operate on each key one by one without disassembling an entire rack of keys. It also dramatically reduces time needed for repairs, allowing a perfect adjusment of the pads in a few seconds. The mechanism uses standardized elements that favor mass-production efficiency and is adaptable to all woodwind instruments.
