Description

2610128 -

  Barrel clarinet with a tubular tenon.

  During its development, the clarinet has been perfected in many ways. This is the case for the body of the clarinet, its geometric conformation, the choice of material, as well as for the keying. Unlike the longitudinal bore of the sound tube, which originally had a constant diameter, clarinets are known whose bore has different diameters in sections. In addition, some sections may be tapered. Sound tubes thus constituted must give, in all the registers, a remarkable clarity

  the various sounds, especially the twelfth and the registers

very high.

  It is further known to provide, in the head (barrel, barrel) of the clarinet, interposed between the spout and the body of the top of the clarinet, a hole which can be closed and released by a key that can be

  operated. We seek to obtain a sound of a

  very pure unit and to increase the range of the sound.

  Known measures all require important and risky work, especially on the body

  from the top of the clarinet and on its keying. Modifications

  cations and subsequent adaptations of the intonation and the emission of the clarinet are thus made

extremely difficult.

  The invention overcomes these disadvantages. It is based on the fact that, in the clarinets known so far, the effective proportion of the entire length of the tube of the clarinet which is reserved for the barrel is

  relatively small, while the barrel is of

  decisive factor for intonation and for

of the clarinet.

  The proportion of the tube length of the clarinet barrel should therefore be as large as possible. But this can only be done one way

  limited, simply lengthening the barrel.

  The binding of the barrel with the beak and with the

  the upper body is carried out, so far, by tenons tu-

  bungs rigidly connected to the barrel. The outside diameter

  The thickness of the tubular post is significantly smaller than the outside diameter of the spout and upper body. The barrel that is so far used has, on its front sides, bores (emboftures) adapted to the diameter

  of the tubular post and the length of the tubular post.

  By threading the tubular posts into the bores, sealed connections are obtained by interlocking between the

  beak, barrel and body from the top of the clarinet.

  The invention resides in the fact that the barrel is provided, on one or on both front sides, with a

  tubular post which can itself be threaded with

  cheetah in a corresponding bore of the upper body

or beak.

  Even if it is already by constituting the front side of the barrel, which is turned towards the body of the top, tubular tenon, one multiplies approximately by three its effective tubular length. If both front sides

  of the barrel are made of tubular posts,

  bends the effective tubular length of the barrel by five. The solution according to the invention therefore substantially increases the influence of the barrel on the intonation and on the emission of the clarinet. It allows to answer, in a way 2 (l1O128

  simple, at the wish of clarinettists and avoids changes

  subsequent events full of risks of

  the upper part of the instrument.

  In the attached drawing, given only for

For example:

  FIG. 1 illustrates the known barrel, and

  Figure 2 the barrel according to the invention.

  Figures 1 and 2 show from top to bottom, in the order of their assembly sequence, the barrel 3 and the connecting part of the body of the top 6 of a clarinet.

  To better understand the invention, the

  directly serving the route are represented

  sectional. Keying is not represented. In the

  known rinses, according to Figure 1, the spout 1 is

  mine in a tubular post 2, whose diameter is smaller than that of the spout 1 and the barrel 3. The barrel 3 comprises, on its front side facing the spout 1, a

  bore 4 adapted in diameter and length to the tubular post

  2. In a corresponding manner, there is provided, on the front side facing the upper body, a bore 5 which serves to receive the tubular post 7 of the

  top body 6. The longitudinal bore of the clarinet

  is shown in the exemplary embodiment,

  in the form of a cylindrical bore of constant diameter

  As. But-we could also foresee any other

  forming holes, for example different diameters

  holes and / or tapered holes. Since he

  As shown in Figure 1, the effective proportion of the longitudinal bore is relatively small in the region

from the barrel 3.

  On the other hand, as shown by the solution according to the invention in FIG. 2, the effective proportion of the length of the bore of barrel 3 is substantially greater, being up to three times greater, than in

the known embodiment.

  FIG. 2 represents an exemplary embodiment

  prefer. The spout 1 and the barrel 3 are, as it is

  hitherto, connected to each other by a tubular

  On the other hand, and unlike the previously known solution, the barrel portion 3i is on the front side facing the body of the barrel.

  6, is provided with a tubular post 8 for receiving

  which the upper body 6 has a bore 9 adapted. As we can see, thanks to this arrangement, the

  effective proportion of the length of the bore is

  due significantly larger in the barrel region than

compared to the known solution.

  It is also possible to provide the two front sides of the barrel with tubular studs, which can then be threaded into corresponding bores of the spout 1 and the upper body 6. In this case, the effective proportion of the longitudinal bore in the barrel 3 is multiplied by about five and so the influence of the

  barrel on the intonation and the emission of the clari-

net is even greater.
