Abstract

The corrector of intonation imperfections in 3 or 4 vlve brass instruments solves the intonation imperfections in all 3 or 4 valve brass instruments (f.e.: trumpet, French horn, ventile trombone, tube, tenor horn, bass tuba, fanfare) in the following way: by means of a compensation slide the adequate adjustments of the pipe length occur. The intonation imperfections in wind instruments are marked by the following: If using the 5th, 6th and 7th pipe length an insufficiency of the instrument’s pipe length occurs. For that reason all three vertical sequences of tones, played at those lengths, are relatively too low. Of the 10 monstly used tones from the harmonics only the following are correct and have an intonation precision: 4 tones (1st, 2nd, 4th and 8th tone). Three tones are too high (3rd, 6th and 9th tone) and three tones are too low (5th, 7th and 10th tone). If, by means of a compensation slide, the basic pipe length is shortened, the intonation of the played tone raises. If, by means of a compensation slide, the basic pipe length is lengthened, the intonation of the played tone is decreased.

DEVICE FOR CORRECTING INTONATIONAL IMPERFECTIONS OF BRASS INSTRUMEN_TS

INVENTION SPECIFICATION

Engineering field

Acoustics, musical instruments, trumpet: G 10 K5/00; 7/00; 9/00.

Technical problem

The intonational imperfection of 3 or 4 valve brass instruments (trumpet, French horn, ventile trombone, tuba, tenor hom, bass tuba, fanfare) are eliminated.

Of the 10 mostly used harmonics

the 1st, 2nd, 4th and 8th tone are exact i.e. achieve an intonational precision, the 3rd, 6th and 9th tone are too high and the 5th, 7th and 10th are too low.

When using the 5th, 6th and 7th pipe length, an insufficiency of the instmment's pipe length arises and for that reason all three of the vertical sequences of tones, played at the aforementioned lengths, are relatively too high.

Present level of technology

So far all produced brass instruments had been intonationally imperfect.

Presentation of the invention's substance

The corrector of intonational imperfection of 3 or 4 valve brass instruments is a compensation slide, built in the instrument's basic pipe length in such a way that the instrument's basic pipe length won't alter if the compensation slide is in the zero position. If one uses the compensation slide to shorten the basic pipe length the intonation of the played tone will increase. If one uses the compensation slide to lengthen the basic pipe length the intonation of the played tone will fall.

The compensation slide's length is 1/15 (in writing: one fifteenth part) of the instrument's basic pipe length. One fifteenth part of the pipe is the pipe length added by actuation of the second instrument's valve.

The zero position of the compensation slide is located at the place representing one third of the distance from the end of the side on which the instmment's basic pipe length is being shortened.

For an easier orientation as regards the zero position, it is possible to fit a spring reaching up to 1/3 (in writing: one third) of the compensation slide's length, measured from that side of the compensation slide in which direction the compensation slide is shortening the total pipe length. By using the described corrector of intonational imperfection of 3 or 4 valve brass instmments, the problem of intonational imperfection of all 3 or 4 valve brass instmments is being solved.

Minute description of the invention's implementation

The building in of the compensation slide has to observe a fine execution of work and given specific conditions in the field of anthropometry.

A fine execution of work includes:

- compliance with the dimensions of the instmment into which the compensation slide is fitted and compliance with the instrument's length;

- use of top-quality materials;

- all solderings and other adjustments have to be precise.

The compliance with given specific conditions in the field of anthropometry includes the following:

- the compensation slide has to be fitted in such a way that a person can use it wihout any obstacle;

- the instmments (subjected to the building in of the compensation slide) should be altered in the following way: change in the way of the pipe deflection, in order to make an easy handling of the compensation slide possible for a person. This enables a use without any obstacle. By removal of the bordering screw the following is achieved: a max. lengthening of the compensation slide and an easy and simple disassembly and assembly of the compensation slide for the purpose of cleaning and lubrication.

Possibilities of an industrial application

Playing 3 or 4 valve brass instruments (f.e. trumpet, French hom, ventile trombone, tuba, flugelhom, tenor hom, bass tuba, fanfare) without a corrector of intonational imperfection of 3 or 4 valve brass instruments causes enormous and unsolvable intonational problems, particulary in extreme dynamics. The inovation corrects the aforementioned imperfection and can be used for solving intonational imperfection in case of the aforementioned 3 or 4 valve brass instmments, in symphony orchestras, military brass bands and other orchestras.

The sales prospect is unsurmisedly great. A great number of instruments is produced in many countries, f.e.: Austria, Argentina, Australia, Belgium, Brazil, Canada, Switzerland, Columbia, The Czech Republic, Slovakia, Germany, Denmark, Spain, France, Greece, Hungary, Hong Kong, Israel, Italy, Japan, Korea, Luxembourg, Malta, Norwegen, The Netherlands, South Afrika, Russia, Sweden, Singapore, Slovenia, America. However, the brass instuments are also used worldwide. The numerousness of instruments, the geography of manufacturers and users reveal the possibility of a huge commercial success: sales prospect and profit.

Claims

PATENT REQUIREMENTS

1. The corrector of intonational imperfection of 3 or 4 valve brass instmments is marked by the following: It solves on the very same principle the intonational imperfection of all 3 or 4 brass instmments (f.e. tmmpet, French hom, ventile trombone, tuba, tenor hom, bass tuba, fanfare). The pipe length is adequately adjusted in the following way: The compensation slide is drawn near to the mouthpiece and the total instrument's pipe length is shortened as required (if the played tone - 5th, 7th and 10th harmonics - is too low) or the compensation slide is moved away from the mouthpiece and thus the total instrument's pipe length is extended as required (if the tone played - 3rd, 6th and 9th harmonics and the tones played at the 5th, 6th and 7th pipe length - are too high).

2. The corrector of intonational imperfection of 3 or 4 valve brass instmments as per 1st requirement is marked by the following: The corrector of intonational imperfection of brass instruments, having a length from 1/3 to 1/30 (optimally 1/15) of the instrument's basic pipe length is built in the instmment's basic pipe length - in such a way that the instrument's basic pipe length won't alter if the slide is in the zero position. If one shortens - by means of the compensation slide - the basic pipe length the intonation of the played tone will increase. If one extends, by means of the compensation slide, the basic pipe length the intonation of the played tone will decrease.

3. The corrector of intonational impelection of 3 or 4 valve brass instruments as per 2nd requirement is marked by the following: The zero position of the compensation slide is located at the place representing 1/3 to 1/30 (optimally 1/3) of the distance, measured from the end of the compensation slide on the side where the instrument's basic pipe length is being shortened.

4. The corrector of intonational imperfection of 3 or 4 valve brass instmments as per 3rd requirement is marked by the following: For an easier orientation as regards the zero position, it is possible to fit a spring reaching from 1/3 to 1/30 (and optimally 1/3) of the compensation slide's length, measured on that side of the compensation slide in which direction the compensation slide is shortening the total pipe length.

5. The corrector of intonational imperfection of 3 or 4 valve brass instmments as per 4th requirement is marked by the following: The building in of the compensation slide must comply with the principle of a fine execution of work and especially with the dimensions of the instrument into which the compensation slide is fitted. The use of adequate materials, precise solderings and other adjustments are essential. A compliance with specific conditions in the field of anthropometry is also absolutely essential. That includes the installation of the compensation slide in such a way that a person can use it without any obstacle. It is necessary to alter the instruments (subjected to the building in of the compensation slide) as regards the pipe deflection. In that way the compensation slide is easy for a person to handle, a person can use it without any obstacle and an easy and simple dissassembly and assembly for clening and lubrication is guaranteed.

SUMMARY

The corrector of intonational imperfection of 3 or 4 valve brass instmments solves the intonational imperfection of all 3 or 4 valve brass instmments (f.e.: trumpet, French hom, ventile trombone, tuba, tenor hom, bass tuba, fanfare) in the following way: The adequate adjustments of the pipe length occur by means of a compensation slide. The intonational imperfection of wind instruments are marked by the following: If one uses the 5th, 6th and 7th pipe length an insufficiency of the instmment's pipe length will arise. For that reason all three vertical sequences of tones, played at those lengths, are relatively too low. Of the 10 mostly used harmonics only the following are correct and have an intonational precision: 4 tones (1st, 2nd, 4th and 8th tone). Three tones are too high (3rd, 6th and 9th tone) and three tones are too low (5th, 7th and 10th tone). If, by means of a compensation slide, one shortens the basic pipe length the intonation of the played tone will increase If, by means of a compensation slide, one lengthens the basic pipe length the intonation of the played tone will fall.
