Description

IMPROVEMENTS TO SAXOPHONES, IN SIGHT

  TO IMPROVE THE SOUNDNESS OF THE DO DIESE NOTES.

  The present invention relates to improvements made to saxophones of all types, with a view to improving the accuracy of the sound of sharp notes. We know that the emission of the note of C sharp medium corresponds, on the saxophones, to a position of the fingering of actuation of the keys for which no key is actuated, which means that all the orifices used for the emission different notes are opened, the sound of the sharp note being then emitted by the hole in the body of

  the instrument closest to the jar.

  For the sharp sharp note, the fingering remains the same and the corresponding sound is always emitted by the same hole of the instrument, but the so-called octave key is manually operated, which, as the name suggests, allows at

  the instrumentalist, with the same skill, to change the octave.

  In practice, we unfortunately encounter, for the emission of the sharp pound, a problem of homogeneity of the sound, because the sound of the medium sharp pound is a little too low, compared to the desired sound, while the sound of the sharp pound acute

is noticeably too high.

  This problem is encountered with all types of saxophones, but it is particularly manifest with the

alto saxophones.

  The present invention aims to remedy this serious drawback and to propose a saxophone in which the sounds of the notes of middle sharp and sharp sharp are much more accurate than with the saxophones of the technique

anterior.

  Indeed, the Applicant has established that the defect in accuracy of the medium sharp pound is due to the fact that the opening section of the emission hole of the sharp pound is too small, while the defect of accuracy of the sharp sharp p comes from too large an opening section of the same emission hole. To make these apparently contradictory structural causes compatible, the Applicant proposes to provide on the saxophone two emitting holes for the C sharp, instead of just one, the two holes being simultaneously open for the emission of the C sharp medium, while only one of the two holes remains open for the emission of the usual sharp, but with an opening section smaller than that of the usual hole, The invention therefore relates to an improved saxophone, comprising, in the usual manner, on the body of the instrument, a hole for the emission of pound notes equipped with a closing plate, which can be actuated manually using a control key to be brought into the closed position against an elastic return member and, on the instrument jar, an octave change orifice equipped with a closing plate which normally closes it, this plate being actuable manually using a key octave to be brought e n open position against an elastic return member, this saxophone being characterized in that: - the emitting hole of the C sharp has a smaller opening section than that of the corresponding hole of the usual saxophones , in order to improve the accuracy of the sound of the sharp sharp, when it is in the open position at the same time as the octave change orifice; - a second hash emission hole, equipped with a closing plate urged in the open position by an elastic return member, is provided on the body of the instrument, at the same level as the usual hole, the section d total opening of the two holes being greater than that of the usual sharp hash hole, so that, when they are simultaneously in the open position, with the octave change orifice in the closed position, the accuracy of the sound of the sharp hash medium they emit is improved; the mechanism for actuating the closing plate of the second emission orifice for the sharp note is such that this plate is driven into the open and closed position at the same time as the closing plate of the usual orifice by the double fa control key, even with the octave key actuated simultaneously, while the closing plate of the second emission hole of the sharp hash is kept in the closed position under the stress of the octave key, when this is actuated, regardless of the position of the closing plate of the usual orifice

of emission of the C sharp.

  It is clear that by providing on the body of the instrument two emitting openings of the C sharp, which are simultaneously open, for the emission of the C sharp medium, with a total opening section greater than that of the orifice of the usual sharp, and only one of which is open, for the emission of the sharp sharp, namely the orifice corresponding to the usual orifice, but with an opening section smaller than that of the latter, it is possible to simultaneously improve the accuracy of the C sound

  medium sharp and that of the acute sharp.

  Various mechanisms for driving the closing plate of the second emission orifice of the sharp number, in response to the request of the control key of the closing plate of the usual orifice and the octave key, can be designed and made by a person skilled in the art, without leaving the

part of the present invention.

  The mechanism which will be described below in more detail therefore has only an exemplary value and is in no way limiting.

  In this description, reference will be made to the drawings

  attached diagrams, in which: FIG. 1 is a side perspective view of an alto saxophone of a usual type; FIG. 2 is a view on a larger scale of a portion of the part A of the saxophone of FIG. 1, improved in accordance with the invention, this view being limited to the two emitting orifices of the C sharp, to their trays closing and synchronization drive mechanism of these plates; FIG. 3 is a view similar to FIG. 2, illustrating the drive in synchronization of the two plates for closing the emission orifices of the C sharp, when the octave key is not stressed, by the usual control spatula of the closing plate of the only usual orifice for emitting the sharp number; Figure 4 is a view similar to Figure 2, illustrating the drive and locking in the closed position of the tray of the second emission orifice of the sharp, under the stress of the octave key, while the key control of the plate of the usual emission orifice for the sharp has not been requested and that this plate is in the open position; FIG. 5 is a view similar to FIG. 4, showing the plates of the two emitting openings of the C sharp in the closed position under the joint stress of the octave key and the control key of the orifice plate usual; Figure 6 is another view of portion A of the saxophone of Figure 1, illustrating the new function

  assigned to the octave key of the instrument.

  We will first refer to Figure 1, which represents a common saxophone, where the jar is designated by the reference 1, the body of the instrument by the reference 2, the flag by the reference 4, and the elbow joining the body 2 and the

pavilion 4 by reference 3.

  The sole purpose of this FIG. 1 is to show the part A targeted by the invention, where there is a plate 5 for controlling the shutter of the usual orifice for emitting the sharp, this plate 5 being normally stressed in open position by an elastic return member which can be driven into the closed position by the spatula

  command 6, requested manually by the instrumentalist.

  There is also a distinction, on the jar 1, the plate 7 for closing the octave change orifice, this plate being normally biased in the closed position by an elastic return member and which can be brought into the open position by the '' instrumentalist, to change octave, in

  manually operating the octave key 8.

  As can be seen in FIGS. 2 to 6, the saxophone according to the invention no longer has one, but two orifices for emitting the C sharp, both naturally arranged at the same level on the body 2 of the instrument. One of these orifices occupies the usual location of the sharp orifice and is provided with the usual shutter plate 5, but it has a smaller opening section than that of the usual orifice, so as to emit a lower sharp, and therefore fairer than the usual sharp pound sound, when open only. The second emitting orifice of the C sharp, provided with a shutter plate 9, which is biased in the open position by an elastic return member, has an opening section such that, when the two orifices are open simultaneously, their total opening section is greater than that of the usual orifice, so as to emit a higher middle sharp sound and, consequently, more

just as usual.

  The plate 5 is secured to a lever 10 (called "tip" in the art), itself secured to a rotation axis 11, which is pivotally mounted on end bearings fixed to the body 2 (not shown ), against a return spring, which normally maintains it in a position such that the plate 5 is in the open position. The control spatula 6, rigidly secured by a lever 13 of the axis 11, allows the player to drive the axis 11 in rotation, by manually pressing the spatula 6, to

  bring the plate 5 into the closed position.

  The plate 9 is, in a similar manner, integral in rotation by a "point" 16 of an axis 17, parallel to the axis 11, mounted pivoting with respect to bearings not shown and biased by a return spring in such a way that the plate 9 is normally in position

opening hours.

  The tip 10 is extended by an arm 14, which urges the end of a lever 15 integral in rotation with an axis 18, perpendicular to the axes 11 and 17 and mounted so as to pivot relative to bearings. A pendulum 19 is also attached to this axis in rotation, disposed on either side of the axis 18 and of which a first end requests a lever 20, integral in rotation with the axis 17, so as to drive this axis in rotation, at the same time as the axis 11, under the stress of the spatula 6. It is thus possible to bring the plates 5 and 9 simultaneously in the closed position (see FIG. 3, where the arrows indicate the movements of the

different organs).

  When the spatula 6 is not stressed, the two plates 5 and 9 normally return both to the open position (see FIG. 2), under the stress of the

  return spring, for the emission of the C sharp medium.

  In order to be able to open only the plate 5, while keeping the plate 9 closed, for the emission of the sharp sharp, it is provided, according to the invention, that, when the octave key 8 is actuated, that - This then opposes the return of the plate 9 to the open position under the stress of its return spring, even when the

  spatula 6 is not requested by the instrumentalist.

  To this end, in accordance with the invention, when the instrumentalist requests the octave key 8, which is also a spatula, this one, in addition to the octave change mechanism, drives in rotation, against d 'a return spring, the axis 21 of which it is integral and which is parallel to the axes 11 and 17. A lever 21, integral with the axis 22 and projecting laterally with respect thereto, thus comes to press on the second end of the pendulum 19. The second end of this pendulum then moves, as previously driving the lever, which rotates as already described the axis 17, to bring the plate 9 in the closed position. In this situation, the plate 5 remains in the open position, but can be actuated normally by the spatula 6, and the arm 14 does not

no longer requests lever 15.

  The invention therefore provides a simple means for remedying the inaccuracies in the accuracy of the middle sharp and sharp sharp notes of the saxophones and for conferring on these instruments an acceptable range of sound accuracy for

the whole range.
