French horn mute

The invention relates to a mute for French horns.

In contrast to other wind instruments, which use a variety of mutes, French horns are usually still stopped by hand. When blowing with the muted sound, the hand is pushed deep into the bell with the fingertips first.
The well-known mutes are usually so small that when blowing with the mutes muted, they are completely sunk into the bell of the French horn, at a great distance from the outer edge of the bell, which has a negative effect on the fullness of the sound.
Equipping the French horn with a special stop valve, as described in patent AT 19378, has also not proven successful. This stop valve makes playing the French horn more difficult and represents an additional effort in the production of the French horn.

In addition, such a valve worsens the tuning of the French horn.

Another stop mute according to DE-OS 26 49 286 has the disadvantage that it, like the other known stop mutes, is made of a material that is foreign to the French horn, such as aluminum, which leads to a distortion of the sound.

Furthermore, the relatively small funnel with the largest clear width of 25 mm to 30 mm does not allow for a great fullness of sound.

The invention presented in the patent claims is based on the task of developing a stuffing damper that is uncomplicated in its manufacture and use and that, due to its design and the

-2-

The material used enables an unadulterated stop sound and a great fullness of sound when blowing the French horn.

This object is achieved according to the invention in particular in that the stop mute is made of the same material as the French horn, namely brass, that the part in which the air is compressed during stopped blowing, namely the cylindrical tube pieces 5 and G ₁ , are arranged so as to be displaceable relative to one another and in this way the optimal and unadulterated stop sound can be achieved and that a great fullness of sound is achieved by the relatively large funnel 7 with the largest clear width of 55 mm to 65 mm.

The invention will be explained in more detail with the aid of a drawing:

In Figure 1, the conical pipe section 3 is placed on the base of the truncated cone-shaped pipe section 2. The truncated cone-shaped pipe section 2 is covered with a layer of cork in order to achieve an airtight connection with the instrument.

At the tip 4 of the conical pipe section 3 there is a circular opening, the diameter of which corresponds to the inner diameter of the cylindrical pipe section 5.

The cylindrical pipe section 5 is firmly connected to the conical pipe section 3 at the tip 4, overlapping. Opposite, the cylindrical pipe section 6 can be seen, which in turn is connected to the conical pipe section 3 at the outer end, overlapping

is firmly connected to the funnel 7. On the side opposite the funnel, the inner end of the pipe section, there is the locking mechanism, which fixes the position of the two cylindrical pipe sections 5 and 6 relative to each other, determined to be optimal, in the assembled state.

Figure 2 shows the stuffing damper in the assembled, closed, i.e. not extended, state.
