Saxophone key
FIELD OF THE INVENTION 
     This invention relates to woodwind musical instruments and particularly to a new key for a saxophone which permits the B flat note in the lower register to be played with the thumb of the left hand. 
     BACKGROUND OF THE INVENTION 
     In conventional saxophones, the keys for playing the notes G♯, C♯, B and B flat form a cluster played by the fingers of the left hand. More specifically, the B and B flat notes are played by alternately pressing the respective keys with the little finger of the left hand. When playing musical selections requiring a transition between B and B flat, the little finger must slide rapidly and smoothly between two adjacent keys; otherwise an improper sound results. This transition is particularly difficult for beginning saxophonists and, with some selections, for accomplished saxophonists. 
     Normally the thumb of the saxophone player&#39;s left hand is placed on the thumb rest. When playing the upper register, it is used to depress a key adjacent the rest; however, when playing the lower register, it is not used except for support of the instrument. 
     SUMMARY OF THE INVENTION 
     We have invented a new key which is located on the body of the saxophone adjacent the thumb rest and which is linked to the B flat key. This new key can be depressed by the thumb of the saxophone player&#39;s left hand when playing a selection in the lower register to sound a B flat note, thus avoiding the need to make the difficult transition of the little finger of the left hand from the B to the B flat keys, or vice versa, to sound these notes in succession. However, if desired, the B flat note can be played either with the little finger or the thumb of the left hand.

     BRIEF DESCRIPTION OF A PRESENTLY PREFERRED EMBODIMENT OF THE INVENTION 
     A conventional saxophone having a body portion 1, mouthpiece portion 2 and horn 3 is shown in FIGS. 1 and 2. Since the invention concerns only a part of the saxophone, only that part will be described in detail hereinafter. 
     A thumb rest 4 is provided for supporting the saxophone with the left hand. Above the thumb rest (as viewed in FIG. 1) is a key 5 for playing the upper register. On the opposite side of the thumb rest from the key 5 is a new key 6 for playing the B flat note in accordance with the present invention. The key 6 is connected through linkage 7 to the B flat key 8 in the cluster 9 of G♯, C♯, B and B♭ keys (FIG. 3). 
     Referring to FIG. 4, the new key 6 comprises a thumb portion 10 located adjacent the thumb rest 4 and having a crescent shape for partially encircling the thumb rest so that the thumb of the left hand can be used to depress the key 6 and to support the saxophone. The key 6 is connected to a rod 11 by a curved arm 12 near one end of the rod. 
     The rod 11 is journaled in supports 13 and 14 which are longitudinally spaced from one another in alignment with the axis of the body portion 1 of the saxophone. 
     A short leg 15 is secured to the rod near its other end and near support 14. The leg extends outwardly from the rod in the opposite direction from the arm 12 and includes a toe portion 16. 
     As shown particularly in FIGS. 4 and 5, a crescent-shaped member 17 is journaled between two trunnions 18 mounted on the body 1. One end 19 of member 17 is positioned over toe portion 16 of the leg 15. The opposite end 20 of the member 17 carries an outwardly extending pin 21 which is adapted to engage a hole 22 in leg 23 which is secured to the underside of the B♭ key and extends downwardly therefrom. 
     OPERATION 
     To play the B flat note, the musician depresses key 6 adjacent the thumb rest using the thumb of the left hand. Depressing the key causes the rod 11 to rock, lifting the toe portion 16 of the leg 15 causing member 17 with pin 20 in hole 22 to push against leg 23, thus pulling the B♭ key down. As in conventional saxophones depression of the B flat key causes, through appropriate linkage, closure of valve 24 and its pad against the pad cup over the tone hole on the side of the horn 3 of the saxophone. 
     Having described a preferred embodiment of the invention, it is to be understood that it may be otherwise embodied within the scope of the appended claims.
