An apparatus for varying the length of the barrel of a woodwind musical instrument by providing adjustability in the length thereof which includes two tubular members which are telescopingly movable with respect to one another and include a primary gear rack mounted on the second tubular member and a rotatably movable adjustment wheel mounted on the first tubular member with a gear fixedly. secured to the adjustment wheel and in engagement with respect to the teeth of the primary gear rack such that movement of the adjustment wheel will cause movement of the primary gear rack and relative movement between the first and second tubular member for adjusting or tuning of the length between the first and second tubular members. Each tubular member defines a bore extending centrally therealong which is coincident on the same longitudinally extending bore axis. A locking device is included for selectively fixedly securing the first and second tubular members with respect to one another as desired. Also a first longitudinal orientation device is positioned on the first tubular member and a second orientation device is positioned on the second tubular member to prevent relative rotational movement thereof to prevent rotational movement therebetween and allow only axial tuning movement therebetween. The longitudinal orientation means will preferably include a key and engaging key slot configuration defined on the two tubular members.
Appareil servant à modifier la longueur du baril d'un instrument de musique à vent. Le dispositif comprend deux éléments tubulaires télescopiques et mobiles l'un par rapport à l'autre de même qu'un support d'engrenage primaire monté sur le deuxième élément tubulaire, une molette de réglage articulée montée sur le premier élément tubulaire ainsi qu'une roue dentée fixée sur la molette de réglage et en prise par rapport aux dents du support primaire d'engrenage, de sorte que le mouvement de la molette de réglage entraîne le mouvement du support primaire d'engrenage et un mouvement relatif entre le premier et le second élément tubulaire. On peut donc ainsi régler ou « accorder » la longueur entre le premier et le second élément tubulaire. Chaque élément tubulaire constitue un logement central dans l'axe longitudinal. Un dispositif de verrouillage sert à fixer sélectivement en place le premier et le second élément tubulaire, l'un par rapport à l'autre. De plus, l'invention comprend un premier dispositif d'orientation longitudinale sur le premier élément tubulaire tandis qu'un second dispositif d'orientation est installé sur le second élément tubulaire pour prévenir tout mouvement relatif de rotation de l'élément et de prévenir tout mouvement rotatif entre les deux éléments et ne permettre que le mouvement de réglage axial. Le dispositif d'orientation longitudinale comprendra de préférence une clé et une rainure de clavetage sur les deux éléments tubulaires.
