Definitions

  • the invention relates to orchestral trumpets with linear or rotary pistons.
  • the object of the invention is to provide a trumpet, in particular a trumpet in B-flat, C, D or E-flat, not exhibiting the defect observed, while essentially retaining the characteristics of a trumpet classic.
  • the bottom of the trumpet's tuning stem has a conical widening and that the lower tube of the tuning slide slides outside the tube secured to the piston set, instead of slide inside, as has been done so far.
  • the tube integral with the piston set is shortened by compared to its conventional length, that is to say that it is shortened relative to the upstream end of the lower tube of the slide in the stop position.
  • the bore is substantially cylindrical and of the same diameter from the upper tube of the tuning slide to departure from the elbow of the pavilion.
  • the lower tube of the tuning slide slides outside the tube secured to the set of pistons.
  • the traditional trumpet 1 in FIG. 1 further comprises the mouth 2, the mouth branch 3 widening conically until the start 4 of the bore.
  • the latter remains cylindrical all along the tuning slide 5, of the tube 6 secured to the set of pistons 7, until the start 8 of the bell bend.
  • FIGs 2 and 3 compare the tuning slides 5 of a classical C trumpet (Fig. 2) and according to the invention (Fig. 3). Naturally, what is said for the trumpet in C will be transposed for the trumpets of another tone.
  • the upper tube 9 of the tuning slide 5, connected by a ferrule 10 to the tuning bracket 11 slides inside the tube 12 terminating the mouth branch 3, and the lower tube 13 of the tuning slide 5, connected by a ferrule 14 to the tuning bracket 11, slides inside the tube 6 secured to the piston set.
  • the wavelength calculations show that, if the stem 11 is divided into six equal intervals (ab, bc, cd, de, ef, fg) counted on the central axis 15 of the stem, from upstream to downstream, from division a corresponding to the start of curvature of the stem to division g corresponding to the end of the curvature of the stem, the velocity bellies of E 4 and D sharp are substantially in the straight sections corresponding to divisions f and g.
  • the belly of the re 4 is in a cross section corresponding to an additional division h, with the same interval as the previous ones, located beyond the tuning stem.
  • the division f (the belly of mi 4) generally falls on the chimney 16 of water key 17, when it is present (the water key is visible in fig. 1, and the chimney of water key n 'has been shown only in Fig. 3).
  • the bore whose nominal diameter D is defined in 4, is cylindrical and uniform all along the tuning slide.
  • the bottom of the stem 11 is conically widened so as to encompass the speed bellies situated at f, g, and h.
  • Conical enlargement therefore begins from the fifth section or inter valle ef to the end g of the bracket, which is connected by the ferrule 14 to the lower tube 13 of the tuning slide 5, which slides this time outside the tube 6 secured to the piston set , whose internal diameter is taken equal to the nominal diameter D of the bore, always defined in 4.
  • the integral tube 6 is shortened relative to the upstream end of the lower tube 13 of the slide in the stop position ( position of figures 2 or 3).
  • the conical widening of the bore begins approximately in the middle of the interval ef, continues until ⁇ , after which the bore remains cylindrical over the interval gh and over approximately half of the next interval (not shown), before returning to nominal diameter D.
  • the dotted curve is established for a classical trumpet.
  • the curve in solid lines shows the accuracy curve of the same trumpet after modification in accordance with the invention.
  • the notes F sharp 2, G 2, C sharp 3 and D 3 remain too high, but they are corrected, in normal play, by the moving slides of the first and third pistons traditionally provided with rings (such as 18, fig.l) or rocker systems provided for this purpose and the use of which is part of the normal play of the instrument.
  • the invention makes it possible to remedy a general defect in the construction of the trumpets.
