Title (EN) PITCH ADJUSTER FOR VALVED BRASS INSTRUMENTS
(FR) DISPOSITIF DE REGLAGE DE LA HAUTEUR DES SONS POUR DES CUIVRES A SOUPAPE
Abstract: front page image
(EN)A pitch adjuster (20) for a valved brass instrument (22) having a tuning slide crook (68) and a third valve slide crook (50) enables play in the just intonation scale and includes a main push rod (38) attached to the tuning slide crook (68), a finger operator (48) attached to the third valve slide crook (50) and slidably mounted on the main push rod (38), a bias spring (54) retaining the finger operator (48) in a normal position, a trigger operator (24) and detent assembly (40, 58) which provides for stopped flat and sharp positions. The trigger operator (24) retracts the main push rod (38) to retract the main tuning slide crook (68) and sharpen the pitch of the note being played. The finger operator (48) extends the main push rod (38) and thereby extends the tuning slide crook (68) and third valve slide crook (50) to flatten the pitch of the note being played. The finger operator (48) may be moved beyond the stopped position, by sliding along the main push rod (38) and compressing the bias spring (54), and further extend the third valve slide crook (50) alone. The dent assembly (40, 58) may be locked to disengage the pitch adjuster (20) and a threaded tuning knob assembly (44) permits adjustment of the relative position of the main push rod (38) with respect to the tuning slide crook (68) to thereby tune the instrument (22) without affecting the pitch adjuster (20).
(FR)Un dispositif de reglage de la hauteur des sons (20) pour un cuivre a soupape (22) ayant un corps de rechange de pompe d"accord (68) et un troisieme corps de rechange de pompe a soupape (50) permet de jouer dans la gamme d"intonation juste et comprend une tige-poussoir principale (38) attachee au corps de rechange de pompe d"accord (68), une touche (48) attachee au troisieme corps de rechange de pompe a soupape (50) et montee en coulissement sur la tige-poussoir principale (38), un ressort de poussee (54) retenant la touche (48) en position normale, un organe de declenchement (24) et un assemblage de detente (40, 58) qui permet les positions arretees sourdes et aigues. L"organe de declenchement (24) retracte la tige-poussoir principale (38) pour retracter le corps de rechange de pompe d"accord (68) et monter le ton de la note jouee. La touche (48) allonge la tige-poussoir principale (38) et par consequent allonge le corps de rechange de pompe d"accord (68) et le corps de rechange de pompe a soupape (50) pour abaisser le ton de la note jouee. La touche (48) peut etre deplacee au-dela de la position arretee, par coulissement le long de la tige-poussoir principale (38) et compression du ressort de poussee (54), et allonge davantage le troisieme corps de rechange de pompe a soupape (50) seulement. L"assemblage de detente (40, 58) peut etre bloque pour degager le dispositif d"ajustement du ton (20) et un assemblage a bouton d"accordage filte (44) permet l"ajustement de la position relative de la tige-poussoir principale (38) par rapport au corps de rechange de pompe d"accord (68) de maniere a accorder l"instrument (22) sans affecter le dispositif d"ajustement du ton (20).
