Abstract
An adjustable tuning barrel is disclosed for use with a woodwind instrument that allows the instrument to be easily tuned during play. The tuning barrel includes a fixed element, an adjusting ring coaxial with the fixed element and held in rotatable contacting relationship therewith, and an extending element in rotatable and threaded relationship with the adjusting ring, and in rotatable and motionally resisting relationship with the fixed element. The adjusting ring is wide enough to be comfortably located and manipulated during play. The fixed and extending elements are adapted to facilitate thermal exchange with the ambient environment.
Claims16
An adjustable tuning barrel for use with a woodwind instrument including a mouthpiece and an instrument body, said tuning barrel comprising:
- an adjusting ring, freely rotatable about its axis of symmetry, said ring including:
- first flange means;
- and
- first thread means disposed on an inner surface of said adjusting ring;
- a fixed element fixable with respect to the body of said woodwind instrument, said fixed element including:
- second flange means, cooperative with said first flange means, for retaining said adjusting ring in rotatably contacting relationship with said fixed element;
- and
- first mating means for attaching said tuning barrel to said body of said woodwind instrument;
- and
- an extending element freely rotatable about its axis of symmetry, said extending element including:
- second thread means disposed on an outer surface of said extending element for threadably engaging said first thread means of said adjusting ring so as to cause said extending element to move coaxially toward or away from said instrument body in response to rotation of said adjusting ring;
- second mating means for attaching said tuning barrel to the mouthpiece of a woodwind instrument;
- and
- a rotation impeder for resisting and permitting rotational and coaxial movement of said extending element with respect to said fixed element, being disposed between and in contact with an inner surface of said fixed element and an outer surface of said extending element.
An adjustable tuning barrel for use with a woodwind instrument including a mouthpiece and an instrument body, said tuning barrel comprising:
- a fixed element, connectable to said instrument body at a distal end, and with a flange at a proximal end;
- an adjusting ring coaxial with said fixed element, and held in rotatable contacting relationship with said fixed element;
- an extending element in rotatable and threaded relationship with said adjusting ring, and in rotatable relationship with said fixed element;
- and
- a motion resistance element disposed between and in contact with an inner surface of said fixed element and an outer surface of said extending element, for providing frictional deterrence against rotational motion of the extending element with respect to the fixed element, while permitting such motion.

- a fixed element, connectable to said instrument body at a distal end, and with a flange at a proximal end;
- an adjusting ring coaxial with said fixed element and held in rotatable contacting relationship with said fixed element;
- an extending element in rotatable and longitudinally advancing relationship with said adjusting ring and said fixed element along an axis of symmetry;
- and
- a motion resistance element disposed between and in contact with an inner surface of said fixed element and an outer surface of said extending element, for providing frictional deterrence against rotational motion of the extending element with respect to the fixed element, while permitting such motion.
