Description

  • The present invention relates to wind musical instruments, the mouth of which communicates with the pavilion, directly or through a tone change circuit, through a barrel. These are in particular brass instruments such as small leathers, such as the trumpet, the bugle, the cornet, the French horn, medium brass instruments such as the viola, the trombone with slide, the trombone with piston, the large brass instruments , such as bass, double bass, tuba, contretuba, helicon, bassophone, bass trombon, double bass trombon, as well as fanfare drum instruments, such as bugle and trumpet-bugle.
  • An instrument of this type is already known, with a cylindrical barrel having an inlet bore communicating with the mouth of the instrument, an outlet bore communicating with the horn of the instrument, a bypass bore and a return bore Document FR-A-424,455 gives an example of such an instrument. The bypass bore communicates with the return bore through a tone change circuit. Means are provided for placing the entry bore in communication with the exit bore which is in its extension or with the bypass bore, the air moving in this case in the barrel by making two 90 ° bends. °. It follows a significant pressure drop very different from that which occurs when air passes in a straight line from the inlet bore to the outlet bore. The instrumentalist must correct this variation by blowing harder. It is very difficult for him to measure exactly the additional force of the breath to compensate for the pressure drop during the change of register.
  • The invention overcomes this drawback with a musical instrument which facilitates the emission, so that the instrumentalist can play more accurately with less effort.
  • The invention therefore relates to a musical instrument, of the type indicated above, in which the inlet bore and the outlet bore are arranged at different levels along the axis of the barrel. Thanks to the distance thus available between the two holes, it is possible to give the light of the rotor putting them in communication, a slightly pronounced curvature which is substantially equivalent for the emission to a passage in a straight line of the entry bore. at the exit hole. This characteristic also makes it possible to arrange the entry bore and the diversion bore at different levels along the axis of the barrel and to use the same light of the rotor to feed as desired from the entry bore the outlet bore or the branch bore, in particular when the outlet bore and the branch bore are arranged symmetrically with respect to the inlet bore. In this case, the emission is exactly the same, whatever the register.
  • According to a preferred embodiment, the entry bore is formed in one of the end faces of the cylindrical barrel and, preferably, is axial. The best results are obtained when the outlet bore and the bypass bore, as well as the case where appropriate, the return bore, are more distant from the front face in which the entry bore is formed than from the opposite front face. Advantageously, the outlet bore, the bypass bore and possibly also the return bore are at the same level along the axis of the barrel, preferably being radial.
  • The invention relates particularly to a wind musical instrument, the mouthpiece (1) of which communicates with the horn (12) directly or by means of a tone change circuit (13) by means of a barrel formed by a cylindrical shell having an inlet bore (3) communicating with the mouth (1), an outlet bore (5) communicating with the horn (12), a bypass bore (6) and a return bore (7) between which is mounted the tone change circuit (13), a cylindrical rotor (8) mounted rotating in the shell with respect to its axis (X, X ') in one of the semi-cylindrical halves of which is formed a first light (9) substantially transverse to the axis (X, X ') of the rotor (8) and in the other semi-cylindrical half, diametrically opposite to the first, of which a second light (10) is formed, one of the ends of which opens onto the lateral face of the rotor (8) in a substantially perpendicular direction e to the axis (X, X '), and a mechanism (15) intended to rotate the rotor (8) around its axis (X, X') relative to the shell so as to put the bore inlet (3) in communication as desired with the outlet bore (5) or with the bypass bore (6) by the second lumen (10), characterized in that the inlet bore is axial and is arranged in one of the front faces of the shell, the other end of the second lumen is axial and opens onto one of the front faces of the rotor (8), and the outlet bore (5) and the bypass bore (6 ) are arranged symmetrically with respect to the inlet bore (3) so that the paths taken by the air to pass from the inlet bore (3) to the outlet bore (5) and from the bore inlet (3) to the branch bore (6) have the same length and the same curvature.
  • In the accompanying drawings, given solely by way of example:
    • FIG. 1 is a partial perspective view of a paper clip according to the invention,
    • FIG. 2 is an exploded view of the barrel of the paper clip of FIG. 1,
    • FIG. 3 is a sectional view along a plane normal to the axis X, X ′ of FIG. 2 and passing through the diameter of a lumen, while the entry bore communicates with the exit bore, and
    • Figure 4 is a view similar to Figure 3, while the inlet bore communicates with the bypass bore.
  • The paper clip shown in Figure 1 has a mouthpiece 1 that the player brings to his mouth and which is extended by a bent pipe 2 called a slide opening into the axial inlet bore 3 of the cylindrical shell 4 of a barrel. The shell of the barrel also includes an outlet bore 5, a bypass bore 6 and a return bore 7. These three holes 5, 6 and 7 are radial and are, in the same transverse plane, more distant from the front face where opens the entry bore 3 only from the opposite front face.
  • In the barrel is mounted rotating a cylindrical rotor 8 comprising in a semi-cylindrical half a lumen 9 substantially transverse to the axis X, X 'of the rotor and a lumen 10 one of the ends of which opens out along an axial orifice in one of the lateral faces of the rotor and the other end of which opens into a radial orifice on the lateral face of the rotor.
  • The outlet bore 5 communicates by a pipe 11 with the roof 12. The bypass bore 6 communicates via a circuit for changing tone 13 with the return bore 7. The pipe 2 and the pipe 1 are connected by a cross-member 14 on which is pivotally mounted a lever or a pallet 15 connected to a crank 16 attacking an axial journal 17 of the rotor and thus allowing the rotate a quarter turn.
  • In FIG. 3, the entry bore 3 communicates by light 10 with the exit bore 5. In FIG. 4, the rotor has rotated 90 °. The inlet bore 3 communicates with the bypass bore 6 by the light 10, while the return bore 7 communicates with the outlet bore 5 by the light 9.
  • The path followed by the air to pass from the inlet bore 3 to the outlet bore 5 or to the bypass bore 6 is exactly the same in length and in curvature. This curvature is all the less pronounced as the holes 5 and 6 are more distant from the front face of the shell, into which the entry bore 3 opens, than from the opposite front face.
