ES2215444A1 - Tunable chanter for bagpipe, has mobile shank equipped in positioning hole of reed, and three independent parts assembled together to form single object to lengthen or reduce tuning function - Google Patents

Abstract

The chanter has three independent parts assembled together to form a single object to lengthen or reduce a tuning function, where the chanter is made of wood material. A mobile shank is equipped in a positioning hole of a reed.

Description

Punteiro (pointer) tunable.

The present invention relates to a punteiro (pointer) for Galician, Asturian or Scottish bagpipe and other similar construction in which remarkable improvements are achieved, by using a sharpened pointer (pointer), which allows to adjust the tuning without manipulating the pallet or straw every time we need to tune the pointer (pointer).

Background of the invention

They are known punteiros (pointers) in which a mobile tudel is incorporated that is located in the hole of pallet placement, which raises the disadvantage that in tuning adjustment it is necessary to remove the punteiro from the bagpipe to regulate such tuning. In addition, the tudel to which we mention, metal fabrication, has a negative impact in the timbre and brightness of the sound of the punteiro (pointer). East tudel has been successfully tested only in punteiros (pointers) Asturian

However, experience has shown that it is possible to improve the characteristics of the punteiro (pointer) mentioned in this section, and consequently a new punteiro has been devised (pointer) whose characteristics are the object of this invention.

Description of the invention

The punteiro (pointer) tuneable for bagpipes Galician, Asturian or Scottish consists of three independent parts that are assembled to form a single object or pointer (pointer) adjustable in size. These three parts come perfectly defined in the attached drawings. The way it affects positively to tuning this construction is as follows:

\ ding {118}

To the reduce and enlarge the size of the punteiro (pointer) in places which are indicated in the accompanying drawings we get approximately half pitch variation in tuning.

\ ding {118}

The part top of the punteiro that hosts the pallet, allows us to vary the tuning of the entire punteiro (pointer) by shortening or lengthening the distance of the pallet with the middle section that groups the sound holes.

\ ding {118}

It is It is essential that the central part of the punteiro (pointer) groups the set of all sound holes as can be seen in the drawings.

\ ding {118}

The part bottom of the punteiro (pointer) or cup should group to the ears of the instrument. When said ears are independent of the central part where the sound holes are grouped, allows us move the cup away or closer to the sound holes by varying the tuning of the most serious punteiro notes (pointer) and helping to stabilize it in low temperatures where these serious notes They suffer a more pronounced decline than the sharp notes.

\ ding {118}

The conicity of the punteiro (pointer) that has been until now the obstacle that prevented the enlargement or reduction of the size of the same ceases to be an obstacle in this type of construction suffering only a few variations or air chambers in the joints of the three parts of the punteiro (pointer). These air chambers do not affect the loudness or timbre or other characteristics of the punteiro (pointer) classic.

Brief description of the drawings

The section (A-B) corresponds to the copete del punteiro (pointer) of conical interior and spiky in its cylindrically based as seen in drawing number 3. The place where the pallet is received undergoes an inversion of the taper to accommodate the conical tudel of the pallet. There must be a space between the end of the pallet tube and the air chamber that causes the junction of the tuft with the middle section, this space should oscillate around five millimeters depending on the tonality of the punteiro (pointer) and therefore of its size since size differences between punteiros of different shades they are usually centimeters, therefore, what is fundamental is that there is a space between the tudel and the cylindrical opening.

The section (C-D-E) It is of conical construction both inside and outside as appreciate in drawing 2. In drawing 3 we see that part C of some 15 mm long (depending on the punteiro) is construction cylindrical and of the same caliber or diameter as the opening cylindrical of the tuft where it should move away. The E part in appearance exterior is conical and cylindrical inside to house the cup of the punteiro (pointer) (drawing 3).

The section (F-G) called cup, is of conical construction in its outer and inner part. In his part upper (drawing 3), part F is transformed into a cylinder that does not must exceed the last sound hole of the part in length central, when the central part and the cup meet assembled in its entirety (drawing 2 and 4), section F is housed in part E of the punteiro.

Drawings 5 and 6 show us a punteiro (pointer) disassembled viewed from the front and from the back respectively. Drawing 1 presents the three parts that make up the punteiro refinable.

Description of a preferred embodiment

The punteiro (pointer) tunable must be built in wood suitable for instrument construction of wind or a substitute of similar characteristics as, for example, the polypenco. The joint joints of the different parts of the punteiro can be covered with different materials that allow the perfect sealing of the joints and therefore the impossibility of the air outlet through said joints. The Materials that have been successfully tested are natural cork and synthetic, o-rings, metal spikes and a coating Silicone or similar. But also, others could be used materials provided that they allow sufficient mobility of parts of the punteiro (pointer) and a correct seal. An example of This type of joint is the clarinet or the joint transverse flutes.

Claims (1)

1. Punteiro or adjustable pointer characterized by: A division into 3 parts of the instrument that allow to reduce or lengthen it depending on the tuning that, in Every moment is required.
