' Claims. (Cl. 84-385) This invention relates generally to the musical arts, and more particularlyto an improved mechanism for producing the harmonics in wind instruments of the open tube or column type.

Various. wind musical instruments, such as the saxophone, oboe, flute,bassoon, etc., are of the type known as open tube instruments, as opposed to wind musical instruments of the closed tube type such as the clarinet.

In order to play the upper or chalumeau register of one' of these instruments, the saxophone, for example, there is provided a pair of octave or 'chalumeau openings respectively positioned near the upper portion of the body, and on the neck of the instrument.

It is; an object of this invention to provide an improved mechanism for controlling the operation of the chainmeau or octave holes of an open tube instrument such as a saxophone.

It is a further object of this invention to provide such a mechanism insuring'proper closing of the octave or chalumeau holes.

It is another object of this operation to provide mechanism for insuring the alternate operation of the two octave or chalumeau holes.

Other and further objects and advantages of the present invention will be apparent from the following .description when taken in connection with the accompanying drawings wherein FIG. 1 is a partial side view of the upper body and neck of a saxophone with most of the holes and mechanisms thereof removed;

FIG. 2 is plan view of the back or underside of the instrument and the corresponding front portion of the mechanism in a developed view; and

FIG. 3 is a detail view of a portion of the mechanism in FIG. 2.

Referring first to FIG. 2, there will be seen a hinge rod pivoted between a pair of bearing posts 12 and 14. It will be understood that the rod may actually be a tube, but it is conventionally spoken of as a hinge rod. A second hinge rod 16 is pivotally mounted in axial alignment withthe hinge rod 10 on the post 14 and another post 18 spaced upwards on the instrument. The bearing post 12 is provided with a needle spring 20 cooperable with a spur or stud (not shown) on the 3,136,199 Patented June 9, 1964 end of the swivel 32 is relieved at 42 for engagement with a spur 44. The spur 44 is integral with a collar 46 fixed on the upper pivot rod 16. A laterally extending arm 48 is also fixed on the pivot rod 16, projecting in the opposite direction from the arms 22 and 28.

.As will be understood, the tone hole 26 is very nearly at the front of the saxophone, while the hinge rod 10 is substantially at the side thereof. Another hinge rod 50 is disposed relatively toward the back of the instrument, and is pivoted between posts 52 and 54. The hinge rod 50 is parallel to the hinge rods 10 and 16, and a laterally extending arm 56 thereon overlies the end of the arm '48. The spring 20 acts through the pivotrod 10, spur 38, swivel. 32, spur 44 and hinge rod 16 normally to maintain the arm 48 in raised position. This normally maintains the arm 56 also in raised position. A laterally extending arm 58 is secured on the hinge rod extending in substantially the opposite direction from the arm 56, and this arm 58 is normally held down. The parts with which this arm directly cooperates will be set forth hereinafter.

A spatual key 60 is disposed longitudinally of the saxophone along the backside thereof, being fixed on a hinge rod 62 pivoted between a pair of posts 63 and 65. The lower end or tail of the spatula 60 is provided with a finger piece or plateau 64 for engagement with the thumb. A thumb rest or elevator 66 is fixed on the body of the saxophone immediately adjacent the finger piece or plateau 64 of the spatula key 60, often referred to as an octave key. A flat spring 68 is fixed on the underside of the key 60 and bears against the body of the saxophone, normally to maintain the finger piece 64 in raised position away from the body of the instrument and substantially on a level with the thumb elevator 66.

The upper or front end of the spatula key 60 is provided with a portion '70 offset outwardly away from the upper portion of the saxophone body. A split post or clevis 72 is fixed on the tip of the offset end' portion 70, and projects back toward the body, having a pivot pin 74 carried transversely therein on which a rocker 76 is pivoted. The upper end or nose 78 of this rocker is provided with an overlie 80 of cork or the like, and the underside thereof manually abuts the upper body portion or neck piece receiver 82. The opposite or lower end of I the rocker 76-underlies theend of the arm 58, and normally is held down'thereby. A slotted head 84 is pivoted by a cross pin 86 in the lower end of the rocker 76, di-

' rectly underlying the arm 58, and'is formed with a key underside of the pivot rod or hinge rod 10. The spring 20 is shown somewhat schematically in conventional fashion. I, A laterally extending arm 22 on the hinge rod 10 carries a key cup and pad 24 for closing a tone hole 26, specifically the G tone hole.- The spring 20 biases the hinge rod 10 to such position as normally to hold the pad 24 off the tone hole 26. An arm 28 is fixed on the pivot rod '10 upwards of the arm 22, and carries a finger piece 30 at the outer end. The finger piece" 30 is engaged by the'ring finger of the left hand for pivotcup 88. carrying a pad 90 closing on a chalurneau or ocdiately overlyingthe upper end or nose 78 of the rocker ing of the hinge rod 10 against the action of the spring,

whereby to close the pad on the G tone'hole 26.

A swivel 32 is pivotally mounted on a pin 34 extending up from the body of the saxophone beneath the upper hinge rod 16. The lower end of the swivel is hooklike in configuration as shown at 36 to extendaround the post 14 into position for engagement by aspur 38 having a collar 40 integral therewith by means of which it is' fixed on the upper end of the hinge rod 10 extending in toward the body of the saxophone. The upper I 76. The upper end ortip of the arm or key 96 is pro- 'vided, with a; key cup 102 having a pad 104- for closing .the upperoctave orchalumeau hole 106. A blade or leaf spring 108 is fixed on the underside of the key 96 and bears against the upper portion of the'neck 94, whereby normally to hold the key 96 toward the neck with the pad 104 in hole closing position against the hole 106.

'The relationship of the parts described is such that when the finger piece 30 alone is depressed, the cup and pad 24 close against the hole 26, the spur 38 simply moving awayfrom theend of the swivel32. (It will be understood that when reference is made to depressing only the finger piece 30, that this completely ignores whatever may be done with the index and second fingers of the left hand, relative to keys and finger pieces spaced above the finger piece 30, since they do not affect the action of the parts herein described). The remaining parts described remain in their normal position.

n the other hand, when the finger piece 64 of the spatula key 60 is depressed alone, the pivot 74 of the rocker 76 is raised. The effective force of the spring is greater than that of the spring N8, and consequently the lower end of the rocker 76 is held down by the arm 58. The upper end of the rocker raises, carrying with it the bight of the bale ltitl, thereby raising the pad 104 from the upper octave or chalumeau hole 1%. The pivot or swivel mounting of the pad for the lower chalumean or octave hole 92 is most important at this point, as it maintains the pad flat in hole closing position, even though the rocker 76 changes its angular position relative to the body of the saxophone.

If both the finger piece 64 of the spatula key at and the finger piece 39 are depressed at the same time, the pivot '74- of the rocker is raised away from the body, and the arm 58 is freed from restraint by the spring 2%. The spring 108 holds the key 96 down in hole closing position, and the bight of the bale 1% presses against the upper end or nose 7% of the rocker '76. Accordingly, the lower end or tail of the rocker rises, lifting the pad 90 from the lower chalumeau or octave hole 92 The keys and finger pieces played by the first two fingers of the left hand have no etiect on the mechanism described. Hence, when these fingers are utilized, playing in'the upper or chalumeau register, with the finger piece 64 depressed by the thumb, the upper chalumeau or octave hole 106 is open, As soon as the ring finger engages and depresses the finger piece 30, the mechanism described effects automatic shifting from the upper chalumean hole 106 to the lower chalurneau hole 92. Con versely, the octave or chalumeau holes automatically switch or reverse when the ring finger is lifted from the finger piece 39. As will now be apparent, there has been disclosed an improved chalumeau or octave mechanism for saxophones and other open tube and wind musical instruments which is of simple and effective construction, and in particular which automatically shifts between the two chalumeau or octave holes as other notes are played, without requiring any additional manipulation or' conscious effort on the part of the musician.'
